New Comet Found
There's a newfound comet closing in on the sun,and when it gets here in 2013,you may be able to see it with your naked eye.
Astronomers stumbled upon the icy interloper on June 5 while searching for potentially hazardous asteroids（小行星）.Equipped with the world's largest digital camera , the University of Hawaii's Pan-STARRS team snagged a faint image of the odd object while it was more than 700 million miles away , between the orbits of Jupiter（木星）and Saturn（土星）.
"Almost everything we find is an asteroid,but this object was suspicious,"said Richard Wainscoat,co-discoverer of the comet and an astronomer at the University of Hawaii."Unlike asteroids, which appear point-like in images,the telltale sign that gave it away was its fuzzy appearance."
By March 2013 the comet,named C/2011 L4(PANSTARRS),is expected to come within 30 million miles of the sun一closer even than the innermost（最深处）planet, Mercury（水星）.
When the comet makes its closest approach to the sun,most of its ices will vaporize,adding to its hazy envelope of gas and dust and producing the familiar tail. This denser envelope,or coma, should boost the comet to peak brightness,making it potentially visible to the naked eye low in the western horizon just after sunset.
While there is no danger of collision with Earth,preliminary calculations of the comet's orbit show that this may be its first and final trip through the solar system."It may be coming around the sun for the first and only time,only to be ejected from the solar system,never to return,"Wainscoat said."Since we don't have a lot of data on it,we really don't know the orbit well enough right now, and it will take up to two months of observations to find out."
Astronomers believe C/2011 L4 may be a runaway from the Oort cloud（奥尔特云）,a reservoir of billions of hibernating（蛰伏）comets that orbits about 100,000 times farther than the distance between Earth and the sun.
The fact that it's going around the back of the sun from our point of view may ultimately affect the comet's visibility,but a lot will depend on how close the body actually gets to the sun.Also, whether the comet is north or south of the sun when it reaches peak brightness will determine which hemisphere on Earth gets the better view.

Friendly Relations with the People Around
1. You depend on all the people closely around to give you the warm feeling of belongingness（归属）that you must have to feel secure.But, in fact,the members of all the groups to which youbelong also depend on you to give that feeling to them .A person who shows that he wants everything for himself is bound（一定的）to be a lonely wolf.
2. The need for companionship is closely related to the need for a sense of belongingness.How sad and lonely your life would be if you had no one to share your feelings and experiences.You may take it for granted that there will always be people around to talk to and to do things with you and for you .The important point,however,is that keeping emotionally healthy does not depend so much upon having people around you as upon your ability to establish relationships that are satisfying both to you and to them.
3. Suppose you are in a crowd watching a football game.You don't know them.When the game is over,you will all go your separate ways.But just for a while you had a feeling of companionship,of sharing the feelings of others who were cheering for the team you wanted to win.
4. An experience of this kind gives the clue（线索）to what companionship really is. It depends upon emotional ties of sympathy,understanding,trust,and affection.Companions become friends when these ties are formed.
5. When you are thrown in a new circle of acquaintances（熟人）,you may not know with whom you will make friends,but you can be sure that you will be able to establish friendships if you show that you really like people.Paragraph 5______
A: Making friends with new acquaintances
B: Close link between companionship and belongingness
C: How to satisfy other people's needs
D: An example of a satisfying relationship
E: Difficulties in establishing friendships
F: What companionship, really is答案：A解析：第二段第一句点明了本段的中心意思：需要陪伴和需要归属感是密切相关的。后面时此做了一些说明。而选项B正是第一句的意思。
第三段以看一场足球赛为例，说明了在看足球赛的过程中所得到的陪伴感，故它是一种令大家都满意的相互关系的好例子。
第四段第一句是主题句，也就是选项F。后面两句给予具体补充、说明。
最后一段说在新认识的人群里，只要你真正喜欢别人，你肯定能与他们建立友谊，故选项A是本题大意。
根据第二段第二句，选择选项B是最恰当的，因为它们之间从内容到文字都完全一样。如果选择选项F则修辞上不通，我们不能说“你的生活将是一匹孤独的狼”。形容为“孤独的狼”应该是人（如第一段最后一句），而不应该是生活。
根据文章第一句选择选项E。该句说，“你依靠你周围亲密的人给你温暖的归属感，有了它你才能感到安全”，本题则说“温暖的归属感可以给你安全感”，两句意思完，全一样。
第二段最后一句说，“保持情感健康，与其说依靠你周围的人，还不如说依靠你与他们建立彼此满意关系的能力”（注意：本句中“not so much... as...”的意思是“与其说是……还不如说是……”）。而选择C项以后本题则说，“与他人建立良好关系的能力可以使你保持情感健康”，两句意思完全一样。
根据最后一段后半部分所说，“如果你表现出真正喜欢别人，你就可以肯定你能与之建立友谊”，可见选择选项D以后就可以与它的意思一致，只是换了一个说法而已， “如果你并不真正喜欢别人，你就会发现很难与他们交朋友”。 -

How We Form First Impression
We all have first impression of someone、just met.But why? Why do we form an opinion about someone without really knowing anything about him or her aside perhaps from a few remarks or readily observable traits?
The answer is related to how your brain allows you to be~of the world.Your brain is so sensitive in picking up facial traits,Even very minor difference in how a person'5 eyes,ears,nose,or mouth are placed in relation to each other makes you see him or her as different.In fact,your brain continuously processes incoming sensory information-the sights and sounds of your world.These incoming signals are compared against a host of "memories"stored in the brain areas called the cortex(皮质）system to determine what these new signals"mean".
If you see someone you know and like at school,your brain says"familiar and safe".If you see someone new it says,"new and potentially threatening".Then your brain starts to match features of this stranger with other"known"memories.The height,weight,dress,ethnicity,gestures,and tone of voice are all matched up.The more unfamiliar the characteristics are,the more your brain may say,"This is new.I don ' t like this person ".Or else , " I'm intrigued（好奇的）".Or your brain may perceive a new face but familiar clothes,ethnicity,gestures-like your other friends;so your brain says,"I like this person".But these preliminary"impressions"can be dead wrong.
When we stereotype people,we use a less mature form of thinking(not unlike the immature thinking of a very young child)that makes simplistic and categorical impressions of others.Rather than learn about the depth and breadth of people-their history,interest
values,strengths,and true character-we categorize them as jocks（骗子）,peeks（反常的人）,or freaks（怪人）.
However,if we resist initial stereotypical impressions,we have a chance to be aware of what a person is truly like.If we spend time with a person,hear about his or her life,hopes,dreams,and become aware of the person's character,we use a different,more mature style of thinking-and the most complex areas of our cortex,which allow us to be humane。If you meet a stranger with familiar gestures,your brain is most likely to say________.
A:"He is familiar and safe."
B:"He is new and potentially threatening."
C:"I like this person."
D:"This is new.I don't like this person."答案：C解析：本文主要讲述了人们对陌生人的第一印象是如何形成的。
由文章第二段第二句和第三句话“Your brain is so sensitive in picking up facial traits.Even very minor difference in...makes you see him or her as different.”可知，大脑对面部特征十分敏感，即使是每个人在眼睛、、耳朵或嘴部的细小差异也会使大脑察觉到其不同之处。由此可步测出，面部特征是我们对陌生人第一印象的重要影响因素。故选C。
由文章第三段倒数第二句话“Or your brain may perceive a new face but familiar clothes.so your brain says , 'I like this person'.”可知，当我们见到-个陌生人，但是他/她的服饰、毛势、民族特征等和我们的朋友相似时，我们的大脑就会产生一种“我喜欢他/她”的信号：故选C。
由文章第三段最后-句话“But these preliminary 'impressions' can be dead wrong.”可知，我们对别人的最初印象可能是完全错误的。"preliminary”意思为“初步的，开始的”，与initial（最初的开始的）意思相近。故选C。simplistic过分简单的；stereotypical模式化的；categorical明确的，至对的。
由文章第四段中“When we stereotype people...Rather than learn about the depth an breadth of people”可知，当我们对-个人形成模式化的印象之后，我们会用-种不成熟的思维方式来看待他，却没有去了解他思想上和人格上的深度和广度。故选A。
文章第-段提出了“为什么我们在还没有真正了解-个人时就已经形成了对他的第－印象？”这个问题；文章第二段前两句说这与大脑如何感知世界是息息相关的，大脑对面部特至十分敏感；文章第二、三和四段进一步论述了这-问题；文章最后一段讲如果我们拒绝模式不的第-印象，那么我们就会用更成熟的思维来了解-个人。由此可看出本文主要讲的是大脑对面部特征的敏锐感知使我们形成了对别人的第一印象。故选B。 -

New Comet Found
There's a newfound comet closing in on the sun,and when it gets here in 2013,you may be able to see it with your naked eye.
Astronomers stumbled upon the icy interloper on June 5 while searching for potentially hazardous asteroids（小行星）.Equipped with the world's largest digital camera , the University of Hawaii's Pan-STARRS team snagged a faint image of the odd object while it was more than 700 million miles away , between the orbits of Jupiter（木星）and Saturn（土星）.
"Almost everything we find is an asteroid,but this object was suspicious,"said Richard Wainscoat,co-discoverer of the comet and an astronomer at the University of Hawaii."Unlike asteroids, which appear point-like in images,the telltale sign that gave it away was its fuzzy appearance."
By March 2013 the comet,named C/2011 L4(PANSTARRS),is expected to come within 30 million miles of the sun一closer even than the innermost（最深处）planet, Mercury（水星）.
When the comet makes its closest approach to the sun,most of its ices will vaporize,adding to its hazy envelope of gas and dust and producing the familiar tail. This denser envelope,or coma, should boost the comet to peak brightness,making it potentially visible to the naked eye low in the western horizon just after sunset.
While there is no danger of collision with Earth,preliminary calculations of the comet's orbit show that this may be its first and final trip through the solar system."It may be coming around the sun for the first and only time,only to be ejected from the solar system,never to return,"Wainscoat said."Since we don't have a lot of data on it,we really don't know the orbit well enough right now, and it will take up to two months of observations to find out."
Astronomers believe C/2011 L4 may be a runaway from the Oort cloud（奥尔特云）,a reservoir of billions of hibernating（蛰伏）comets that orbits about 100,000 times farther than the distance between Earth and the sun.
The fact that it's going around the back of the sun from our point of view may ultimately affect the comet's visibility,but a lot will depend on how close the body actually gets to the sun.Also, whether the comet is north or south of the sun when it reaches peak brightness will determine which hemisphere on Earth gets the better view.The newfound comet is made from mercury.

题干意思为：在不断接近太阳的过程中，彗星的冰会融化。第五段第一句中：When the comet makes its closest approach to the sun , most of its ices will vaporize…当彗星靠近太阳时，大部分冰会融化……可以推断出题干与原文意思一致。
题干意思为：天文学家掌握了太阳系的很多信息。通读全文，提到太阳系的只有第六段：Since we don't have a lot of data on it…由于我们并未掌握太多的信息……由此可知，题干意思与该句表达冲突，所以选择B。
题干意思为：北半球能更好地观测彗星。文中最后一段最后一句：Also, whether the comet is north or south of the sun when it reaches peak brightness will determine which hemisphere on Earth gets the better view．当彗星达到最亮值时，它在太阳的南面还是北面将决定在地球哪个半球能够更好地观测彗星。可以推知，哪一个半球观测效果好取决于彗星的位置，所以题干表述错误。
题干意思为：理查德·文斯考特是彗星的发现者之一。文中第三段第一句后半句：…co-discoverer of the comet and an astronomer at the University of Hawaii.……是彗星的共同发现者之一，也是夏威夷大学的天文学家。可以推知，题干与该句意思一致。
题干意思为：C/2011 L4彗星将在2013年撞上地球。文中第六段第一句指出：While there is no danger of collision with Earth…虽然不存在撞击地球的危险性……可以推知，题干意思与原文意思相悖。 -

How We Form First Impression
1 We all have first impression of someone we just met.But why?Why do we form an opinion about someone without really knowing anything about him or her-aside perhaps from a few remarks or readily observable traits.
2 The answer is related to how your brain allows you to be aware of the world.Your brain is so sensitive in picking up facial traits,even very minor difference in how a person's eyes,ears,nose,or mouth are placed in relation to each other makes you see him or her as different.In fact,your brain continuously processes incoming sensory information-the sights and sounds of your world.These incoming"signals"are compared against a host of"memories"stored in the brain areas called the cortex system to determine what these new signals"mean".
3 if you see someone you know and like at school,your brain says"familiar and safe".If you see someone new,it says,"new-potentially threatening".Then your brain starts to match features of this stranger with other "known" memories.The height,weight,dress,ethnicity,gestures,and tone of voice are all matched up.The more unfamiliar the characteristics are,the more your brain may say,"This is new.I don't like this person".Or else, "I'm intrigued".Or your brain may perceive a new face but familiar clothes,ethnicity,gestures-like your other Friends;so your brain says,"I like this person".But these preliminary"impressions"can be dead wrong.
4 When we stereotype people,we use a less mature form of thinking(not unlike the immature thinking of a very young child)that makes simplistic and categorical impressions of others.Rather than learn about the depth and breadth of people-their history,interest,values,strengths,and true character-we categorize them as jocks,geeks,or freaks.
5 However,if we resist initial stereotypical impressions,we have a chance to be aware of what a person is truly like.If we spend time with a person,hear about his or her life,hopes,dreams,and become aware of the person's character,we use a different,more mature style of thinking-and the most complex areas of our cortex,which allow us to be humane.You interpret______by comparing it against the memories already stored in your brain.
A:a stranger's less mature type of thinking
B:the most complex areas of our cortex
C:the immature form of,thinking of a very young child
D:the meaning of incoming sensory information
E:the sights and sounds of the world
F:an opportunity to analyze different forms of thinking答案：D解析：本段讲述的是人脑是如何进行认知的。人脑解读感官信息的过程是大脑将这些信号与储存在大脑皮层系统的大量记忆相比较，以确定这些新收到的信号的意思。故选D。
本段举例说明人脑对第一印象的解读过程，是将第二段叙述的内容具体化。故选C。
本段主要说我们用一种欠成熟的思维方式去对别人做出简单并且绝对化的判断，而没有从深度和广度上了解他们。所以本段主要对第一印象进行了评价。故选B。
本段讲到如果我们与某个人多接触，我们对这个人的认识就不会停留在第一印象的阶段，而是进入一个更深的层次。这是摆脱不成熟的第一印象的方法。故选A。
由第二段第三句话“…your brain continuously processes incoming sensory information-thesights and sounds of your world.”可知，大脑一直不断地对收到的感官信息进行处理―包括影像和声音。故选E。
由第二段第四句话“These incoming ‘ signals ' are compared against a host of host of ‘memories' stored in the brain… to determine what these new signals‘mean’.”可知，大脑将这些信号与储存在大脑皮层系统的大量记忆相比较，以确定这些新收到的信号的意思。故选D。
由第四段第一句话“When we stereotype people … ( not unlike the immature thinking of a very young child )…”可知，当我们对别人形成模式化的看法时，我们会用一种不成熟的思维方式（与小孩子不成熟的想法一样）去做出判断。故选C。
由第五段第二句话“…we use a different , more mature style of thinking and the most complex areas of our cortex …”可知，我们用更成熟的方式去思考，即用大脑皮层中最复杂的区域进行思考，而这使我们变得更有大清味。故选B。 -

Friendly Relations with the People Around
1. You depend on all the people closely around to give you the warm feeling of belongingness（归属）that you must have to feel secure.But, in fact,the members of all the groups to which youbelong also depend on you to give that feeling to them .A person who shows that he wants everything for himself is bound（一定的）to be a lonely wolf.
2. The need for companionship is closely related to the need for a sense of belongingness.How sad and lonely your life would be if you had no one to share your feelings and experiences.You may take it for granted that there will always be people around to talk to and to do things with you and for you .The important point,however,is that keeping emotionally healthy does not depend so much upon having people around you as upon your ability to establish relationships that are satisfying both to you and to them.
3. Suppose you are in a crowd watching a football game.You don't know them.When the game is over,you will all go your separate ways.But just for a while you had a feeling of companionship,of sharing the feelings of others who were cheering for the team you wanted to win.
4. An experience of this kind gives the clue（线索）to what companionship really is. It depends upon emotional ties of sympathy,understanding,trust,and affection.Companions become friends when these ties are formed.
5. When you are thrown in a new circle of acquaintances（熟人）,you may not know with whom you will make friends,but you can be sure that you will be able to establish friendships if you show that you really like people.If you had no one to share your feelings,your life would be______.
A: without pity
B: sad and lonely
C: emotionally healthy
D: without real love for them
E: a sense of security
F: a lonely wolf答案：B解析：第二段第一句点明了本段的中心意思：需要陪伴和需要归属感是密切相关的。后面时此做了一些说明。而选项B正是第一句的意思。
第三段以看一场足球赛为例，说明了在看足球赛的过程中所得到的陪伴感，故它是一种令大家都满意的相互关系的好例子。
第四段第一句是主题句，也就是选项F。后面两句给予具体补充、说明。
最后一段说在新认识的人群里，只要你真正喜欢别人，你肯定能与他们建立友谊，故选项A是本题大意。
根据第二段第二句，选择选项B是最恰当的，因为它们之间从内容到文字都完全一样。如果选择选项F则修辞上不通，我们不能说“你的生活将是一匹孤独的狼”。形容为“孤独的狼”应该是人（如第一段最后一句），而不应该是生活。
根据文章第一句选择选项E。该句说，“你依靠你周围亲密的人给你温暖的归属感，有了它你才能感到安全”，本题则说“温暖的归属感可以给你安全感”，两句意思完，全一样。
第二段最后一句说，“保持情感健康，与其说依靠你周围的人，还不如说依靠你与他们建立彼此满意关系的能力”（注意：本句中“not so much... as...”的意思是“与其说是……还不如说是……”）。而选择C项以后本题则说，“与他人建立良好关系的能力可以使你保持情感健康”，两句意思完全一样。
根据最后一段后半部分所说，“如果你表现出真正喜欢别人，你就可以肯定你能与之建立友谊”，可见选择选项D以后就可以与它的意思一致，只是换了一个说法而已， “如果你并不真正喜欢别人，你就会发现很难与他们交朋友”。 -

How We Form First Impression
We all have first impression of someone、just met.But why? Why do we form an opinion about someone without really knowing anything about him or her aside perhaps from a few remarks or readily observable traits?
The answer is related to how your brain allows you to be~of the world.Your brain is so sensitive in picking up facial traits,Even very minor difference in how a person'5 eyes,ears,nose,or mouth are placed in relation to each other makes you see him or her as different.In fact,your brain continuously processes incoming sensory information-the sights and sounds of your world.These incoming signals are compared against a host of "memories"stored in the brain areas called the cortex(皮质）system to determine what these new signals"mean".
If you see someone you know and like at school,your brain says"familiar and safe".If you see someone new it says,"new and potentially threatening".Then your brain starts to match features of this stranger with other"known"memories.The height,weight,dress,ethnicity,gestures,and tone of voice are all matched up.The more unfamiliar the characteristics are,the more your brain may say,"This is new.I don ' t like this person ".Or else , " I'm intrigued（好奇的）".Or your brain may perceive a new face but familiar clothes,ethnicity,gestures-like your other friends;so your brain says,"I like this person".But these preliminary"impressions"can be dead wrong.
When we stereotype people,we use a less mature form of thinking(not unlike the immature thinking of a very young child)that makes simplistic and categorical impressions of others.Rather than learn about the depth and breadth of people-their history,interest
values,strengths,and true character-we categorize them as jocks（骗子）,peeks（反常的人）,or freaks（怪人）.
However,if we resist initial stereotypical impressions,we have a chance to be aware of what a person is truly like.If we spend time with a person,hear about his or her life,hopes,dreams,and become aware of the person's character,we use a different,more mature style of thinking-and the most complex areas of our cortex,which allow us to be humane。Which of the following statements best expresses the main idea of the passage?
A:One's physical appearance can influence our first impression.
B:Our first impression is influenced by the sensitivity of our brain.
C:Stereotypical impressions can be dead wrong.
D:We should adopt mature thinking when getting to know people.答案：B解析：本文主要讲述了人们对陌生人的第一印象是如何形成的。
由文章第二段第二句和第三句话“Your brain is so sensitive in picking up facial traits.Even very minor difference in...makes you see him or her as different.”可知，大脑对面部特征十分敏感，即使是每个人在眼睛、、耳朵或嘴部的细小差异也会使大脑察觉到其不同之处。由此可步测出，面部特征是我们对陌生人第一印象的重要影响因素。故选C。
由文章第三段倒数第二句话“Or your brain may perceive a new face but familiar clothes.so your brain says , 'I like this person'.”可知，当我们见到-个陌生人，但是他/她的服饰、毛势、民族特征等和我们的朋友相似时，我们的大脑就会产生一种“我喜欢他/她”的信号：故选C。
由文章第三段最后-句话“But these preliminary 'impressions' can be dead wrong.”可知，我们对别人的最初印象可能是完全错误的。"preliminary”意思为“初步的，开始的”，与initial（最初的开始的）意思相近。故选C。simplistic过分简单的；stereotypical模式化的；categorical明确的，至对的。
由文章第四段中“When we stereotype people...Rather than learn about the depth an breadth of people”可知，当我们对-个人形成模式化的印象之后，我们会用-种不成熟的思维方式来看待他，却没有去了解他思想上和人格上的深度和广度。故选A。
文章第-段提出了“为什么我们在还没有真正了解-个人时就已经形成了对他的第－印象？”这个问题；文章第二段前两句说这与大脑如何感知世界是息息相关的，大脑对面部特至十分敏感；文章第二、三和四段进一步论述了这-问题；文章最后一段讲如果我们拒绝模式不的第-印象，那么我们就会用更成熟的思维来了解-个人。由此可看出本文主要讲的是大脑对面部特征的敏锐感知使我们形成了对别人的第一印象。故选B。 -

New Comet Found
There's a newfound comet closing in on the sun,and when it gets here in 2013,you may be able to see it with your naked eye.
Astronomers stumbled upon the icy interloper on June 5 while searching for potentially hazardous asteroids（小行星）.Equipped with the world's largest digital camera , the University of Hawaii's Pan-STARRS team snagged a faint image of the odd object while it was more than 700 million miles away , between the orbits of Jupiter（木星）and Saturn（土星）.
"Almost everything we find is an asteroid,but this object was suspicious,"said Richard Wainscoat,co-discoverer of the comet and an astronomer at the University of Hawaii."Unlike asteroids, which appear point-like in images,the telltale sign that gave it away was its fuzzy appearance."
By March 2013 the comet,named C/2011 L4(PANSTARRS),is expected to come within 30 million miles of the sun一closer even than the innermost（最深处）planet, Mercury（水星）.
When the comet makes its closest approach to the sun,most of its ices will vaporize,adding to its hazy envelope of gas and dust and producing the familiar tail. This denser envelope,or coma, should boost the comet to peak brightness,making it potentially visible to the naked eye low in the western horizon just after sunset.
While there is no danger of collision with Earth,preliminary calculations of the comet's orbit show that this may be its first and final trip through the solar system."It may be coming around the sun for the first and only time,only to be ejected from the solar system,never to return,"Wainscoat said."Since we don't have a lot of data on it,we really don't know the orbit well enough right now, and it will take up to two months of observations to find out."
Astronomers believe C/2011 L4 may be a runaway from the Oort cloud（奥尔特云）,a reservoir of billions of hibernating（蛰伏）comets that orbits about 100,000 times farther than the distance between Earth and the sun.
The fact that it's going around the back of the sun from our point of view may ultimately affect the comet's visibility,but a lot will depend on how close the body actually gets to the sun.Also, whether the comet is north or south of the sun when it reaches peak brightness will determine which hemisphere on Earth gets the better view.Astronomers found a new comet by naked eye.

题干意思为：北半球能更好地观测彗星。文中最后一段最后一句：Also, whether the comet is north or south of the sun when it reaches peak brightness will determine which hemisphere on Earth gets the better view．当彗星达到最亮值时，它在太阳的南面还是北面将决定在地球哪个半球能够更好地观测彗星。可以推知，哪一个半球观测效果好取决于彗星的位置，所以题干表述错误。
题干意思为：理查德·文斯考特是彗星的发现者之一。文中第三段第一句后半句：…co-discoverer of the comet and an astronomer at the University of Hawaii.……是彗星的共同发现者之一，也是夏威夷大学的天文学家。可以推知，题干与该句意思一致。
题干意思为：C/2011 L4彗星将在2013年撞上地球。文中第六段第一句指出：While there is no danger of collision with Earth…虽然不存在撞击地球的危险性……可以推知，题干意思与原文意思相悖。 -
