2.We've already sent out the invitation cards, but we don't know how many people_________.A.comeB.are comingC.cameD.have come

3.Passage TwoWhen we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object outof the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.40. We should take good care of our eyes ______.A. only when we cannot see perfectlyB. only when we can see wellC. even if we can see wellD. only when we realize how important our eyes are

    Clinical Trials

    1 Many clinical trials are done to see if a new drug or device is safe and effective for people
    to use .Sometimes clinical trials are used to study different ways to use the standard
    treatments so they will be more effective,easier to use,and/or decrease side effects.
    Sometimes,studies are done to learn how to best use the treatment in a different group,
    such as children,in whom the treatment was not previously tested.
    2 It is important to test drugs and medical products in the people they are meant to help,It
    is also important to conduct research in a variety of people because different people may
    respond differently to treatments.Some people participate in clinical trials because they
    have exhausted standard treatment options.Other people participate in trials because they
    want to contribute to the advancement of medical knowledge.
    3 The FDA（食品及药物管理局）works to protect participants in clinical trials and to
    ensure that people have reliable information as they decide whether to join a clinical trial.
    Although efforts are made to control the risks to clinical trial participants,some risks may be
    unavoidable because of the uncertainty inherent（内在的）in medical research studies
    involving new medical treatments.
    4 People should learn as much as possible about the clinical trials that interest them.They
    should also feel comfortable discussing their questions and concerns with members of the
    health care team. Prospective（预期的）participants should understand what happens
    during the trial,the type of health care they will receive,and any costs to them.Anyone
    considering a clinical trial should also know that there are benefits and risks associated with
    participating.

    Reliable information should be available to_________.
    A: for some patients
    B: before participation
    C: in humans
    D:medical knowledge

    Stomach Ulcer
    Stomach ulcers are the cause of severe pain for many people.Doctors have been able to help lessen the pain of ulcers.They could not cure them.Now doctors have discovered a cause of ulcers.This means they may have found a way to cure people who suffer from the stomach pain.Studies show that ten percent of the population will develop an ulcer at some time in their life.So a possible cure is good news for many people.
    Ulcers are wounds in the stomach that are similar to small cuts or tears.These wounds can harm the tissue in the stomach,the pipe that carries the food to the stomach or parts of the small intestines.Fluids in the stomach then increase the pain of an ulcer.How does a person know he or she has an ulcer?Doctors say most people with ulcers feel a burning pain in their chest or stomach.This pain often is called heart burn.It usually happens before eating or during the night.It causes some people to lose their desire to eat,or they are unable to keep food in their stomachs.Doctors believed that ulcers were caused by unusually strong stomach fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H.Pillorie.H.Pillorie bacteria are what make stomach produce extra stomach fluid.Doctors found that they can kill the bacteria with medicines called antibiotics.Health experts say the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs.They also believe curing ui- cers will reduce the number of people who develop stomach cancer.The number of people with stomach cancer is very high in Japan,Southeast Asia and parts of Africa.
    Doctors say a person is more likely to get an ulcer if his or her family has had one.In fact a person with the family history of ulcers is three times more likely to get one than other peo-ple.There are ways people can protect themselves from developing an ulcer.Doctors say it is more important to reduce the amount of strong fluids in the stomach.To do this,doctors say,people should not smoke cigarettes or drink alcohol.And they say people should reduce tension in their lives.

    Some people are likely to suffer from the stomach pain at some time in their life.
    A:Right
    B:Wrong
    C:Not mentioned

    答案：A
    解析：
    阅读下面这篇短文，短文后列出了七个句子，请根据短文的内容对每个句子作出判断。如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文章中没有提及，请选择C。
    【解析】
    题干意为“过去医生对于胃溃疡是无能为力”。利用题干中的细节信息词/短 语in the past, doctors作为定位线索，在第一段找到相关句：Doctors have been able to help lessen the pain of ulcers.They could not cure them．相关句意为“医生一直能够帮助减少溃疡造成的痛苦。但是他们不能治愈胃溃疡这种疾病”，由此可见在过去医生虽然不能治愈胃溃疡，但也能对这种疾病进行治疗，因此题干陈述的意义与短文内容不一致。该题主要考查对时态意义的理解：相关句使用了现在完成时态，这表明“减少胃溃疡造成的疼痛（即治疗胃溃疡）”是从过去持续到现在的动作，这也就说明在过去就能对胃溃疡进行治疗。
    题干意为“现在医生能成功地治愈胃溃疡” 该句在句意上与上题有关：一个说过去的情况，一个说现在的情况，因此从上一题的相关句的位置往下找该题相关句，同时关注题干中的细节信息词now , doctors，题干中出现的修饰词successfully在查找相关句的过程中也 需要关注，这样在第一段找到相关句：Now doctors have discovered a cause of ulcers.This means they may have found a way to cure people who suffer from the stomach pain．该句意为“现在医生们已经发现了溃疡的一种致病原因。这就意味着他们可能已经找到一种方法来治疗那些遭受到胃痛困扰的人”，由此不难看出题干与该句的内容不一致：题干在肯定地陈述一个事实：能成功治愈胃溃疡；短文说只是可能：“可能找到治疗方法”，即现在治愈胃溃疡只是一种可能（提示：混淆 “可能性”和“事实”是阅读判断题中“错误”这个答案选项常见的出题形式）。
    题干意为“有些人可能在一生中的某个时候遭受胃溃疡这种疾病的困扰”。利用题干中的细节信息词/短语some people, at some time in their life作为定位线索，这样在 第一段中找到该题相关句：Studies show that ten percent of the population（与some people 呼应）will develop an ulcer at some time in their life．该句意为“研究显示10%的人在他们一生中的某个时候可能遭受胃溃疡的困扰”。很明显，这与题干意义一致。
    题干意为“经过多年的实验后医生已经发现了溃疡的一种致病原因”。利用 题干中的细节信息词/短语doctors, a cause of ulcers,after many years of experiments作为定 位线索，在第一段找到涉及到doctor和a cause of ulcers相关的句子：Now doctors have dis-covered a cause of ulcers．该句没有提到many years of experiments“许多年的试验”，而短文中的其他部分也没有出现many years of experiments，由此可见“是否医生们是经过许多年的试验后才发现溃疡的一种致病原因”是无法从短文中了解到的信息，因此题干陈述的信息是短文中未提及的信息（提示：题干中只要有一部分信息是短文中未提及的信息，就可以由此判断题干陈述的信息是短文中未提及的信息）。
    题干意为“医生对胃溃疡的致病原因的理解已经有了变化”。利用题干中的 细节信息词/短语change, doctors's understanding, the cause of stomach ulcer作为定位线 索，这样找到相关句：Doctors believed（与 doctors' understanding呼应）that ulcers were caused（与the cause of stomach ulcer)by unusually strong stomach fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused（与the cause of stom- ach ulcer)by a bacterial organism called Hillico Bactor Pilorie or H.Pillorie．这两个句子提到“医生过去认为溃疡是由胃里超强的液体流动造成的。现在他们发现大多数的胃溃疡是由细菌造成的……”，这两个句子通过陈述医生们过去对溃疡的理解和现在对溃疡的理解来说明医生对溃疡的理解已经有了变化，很明显，题干意义就是对这两个相关句意义的概括（提示：有的题干是对短文中相关句子意义的概括总结）。
    题干意为“胃溃疡会导致胃癌”。利用题干中的细节信息短语stomach cancer 作为定位线索词，这样在第二段的结尾部分找到相关句：They also believe curing ulcers will re- duce the number of people who develop stomach cancer．该句意为“他们认为治愈溃疡能够减少患胃癌的人数”，由此可知胃溃疡是造成胃癌的一个原因，题干陈述的信息与短文内容一致。
    题干意为“喜欢吃辛辣食物的人容易患胃溃疡”。利用题干中的细节信息短语a lot of spicy food作为定位线索，结果发现短文中根本没有谈到spicy food，由此可知短文中根本没有涉及到辛辣食物和胃溃疡之间的关系，因此无法依据短文判断出是否喜欢吃辛辣食物的人容易患胃溃疡，由此判断题干陈述的信息为短文中未提及的信息。

  • 第7题：

    根据下列内容，回答211-215题。
    A house is the most expensive thing most people will ever buy．Very few people have enough money of their own to buy a house，so they have to borrow money from a bank．Borrowing moneyfrom a bank to buy a house is called“take a mortgage”．The bank usually lends money or gives a me．gage for twenty—five years．Houses are so expensive that many people nowadays have to borrow as much as$50，000．In other words，they will have a$50，000 mortgage．
    How can you get a mortgage? When you find a house you like．you go to a bank．The bank will research you financial history and decide if they think you are a good risk．They will want to know what kind of job you have，what kind of salary you make and how long you have had the job．
    They will a]so want to know how much money you have．In addition．the banks will require a down payment．Depending Oil which state you live in，the bank may require as much as 30%of the price of the house as a down payment．The bank will then lend you the rest of the money to buy the house.Many people are never able to buy a house because they can not save enough money for the
    down payment．
    What does a house mean in the United States．? __________

    A.It is a dream which many people can hardly realize
    B.It is so expensive that many people can not really buy them
    C.It is the most important property that many people try to buy
    D.It doesn’t belong to people if they can not borrow morley from the bank

    答案：C
    解析：
    从第一句“A house is the most expensive thing most people will ever buy”可知，房子是人们所要购置的最重要的财产。故C项正确。A、B项都提到买房子的不可能性，与文章中的抵押贷款从而购房相悖。D项过于绝对化，并不是所有的人都必须通过银行贷款才买得起房子。

    Stomach Ulcer

    Stomach ulcers are the cause of severe pain for many people.Doctors have been able to help lessen the
    pain of ulcers.They could not cure them.Now doctors have discovered a cause of ulcers.This means they
    may have found a way to cure people who suffer from the stomach pain.Studies show that ten percent of the
    population will develop an ulcer at some time in their lives.So a possible cure is good news for many people.
    Ulcers are wounds in the stomach that are similar to small cuts or tears.These wounds can harm the
    tissue in the stomach,the pipe that carries the food to the stomach or parts of the small intestines.Fluids in
    the stomach then increase the pain of an ulcer. How does a person know he or she has an ulcer? Doctors say
    most people with ulcers feel a burning pain in their chests or stomachs.This pain is often called heartburn.It
    usually happens before eating or during the night. It causes some people to lose their desire to eat,or they are
    unable to keep food in their stomachs.Doctors believed that ulcers were caused by unusually strong stomach
    fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused by a bacterial

    believe curing ulcers will reduce the number of people who develop stomach cancer. The number of people
    with stomach cancer is very high in Japan,Southeast Asia and parts of Africa.
    Doctors say a person is more likely to get an ulcer if someone in his or her family has had one.In fact a
    person with the family history of ulcers is three times more likely to get one than other people.There are ways
    people can protect themselves from developing an ulcer. Doctors say it is more important to reduce the amount
    of strong fluids in the stomach.To do this,doctors say,people should not smoke cigarettes or drink alcohol.
    And they say people should reduce tension in their lives.

    Doctors have discovered a cause of ulcers after many years of experiments.
    A:Right
    B:Wrong
    C:Not mentioned

    答案：C
    解析：
    由文章第一段的第二、三句“Doctors have been able to help lessen the pain of ulcers.They could not cure them.”可知，过去，医生们虽然不能治愈胃溃疡，但可以减轻胃溃疡造成的疼痛。 故B为正确答案。
    由文章第一段的内容可知，医生们发现了一种能引起胃溃疡的病因，这有可能使医生 们找到治愈此病的方法，但这只是一种可能性。故B为正确答案。
    由文章第一段倒数第二句“Studies show that ten percent of the population will develop an ulcer at some time in their lives.”可知，全世界百分之十的人口在其一生中会得胃溃疡。故A 为正确答案。
    文章前两段只是说医生们找到了一种引发胃溃疡的病因，但并没有提及发现这种病因 耗费的时间或者过程。故C为正确答案。
    由文章第二段的倒数第六句“Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H Pilorie.”可知，现在医生们发现胃溃疡是一种 细菌导致的，这是医生对胃溃疡病因理解的改变。故A为正确答案。
    借助常识和背景知识判断该句的说法正确，所以答案可能为“正确”或“没提到”。借助 题干中的特征词stomach cancer作为答案线索词，这样在第2段的结尾部分找到答案相关句 (They also believe curing ulcers will reduce the number of people who develop stomach cancer．他们 相信治愈溃疡能够减少胃癌的认输），确认题干句的说法正确。
    借助题干中的spicy food作为答案线索词，发现文章中根本没有谈到spicy food，所以判 断该题的说法为“没提到”。

    资料：When we see well，we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
    People who are near-sighted can only see things that are very close to their eyes，Everything else seems blurry（=unclear）.Many people who do a lot of work，such as writing，reading and sewing become near-sighted.
    People who are far-sighted suffer from just the opposite problem. They can see things that are far away，but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading，they must get glasses，too.
    Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism. This，too，can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now，however，it is possible to operate on the cataracts and remove them.

Many clinical trials are done to see if a new drug or device is safe and effective for people to use.Sometimes clinical trials are used to study different ways to use the standard treatments so they will be more effective,easier to use,and/or decrease side effects.Sometimes,studies are done to learn how to best use the treatment in a different population,such as children,in whom the treatment was not previously tested.
    2. It is important to test drugs and medical products in the people they are meant to help.It is also important to conduct research in a variety of people because different people may respond differently to treatments.Some people participate in clinical trials because they have exhausted standard treatment options .Other people participate in trials because they want to contribute to the ad-vancement of medical knowledge.
    3. The FDA（食品及药物管理局）works to protect participants in clinical trials and to ensure that people have reliable information as they decide whether to join a clinical trial.Although efforts are made to control the risks to clinical trial participants,some risks may be unavoidable because of the uncertainty inherent（内在的）in medical research studies involving new medical treatments.

    Ulcers are wounds in the stomach that are similar to small cuts or tears.These wounds can harm the tissue in the stomach,the pipe that carries the food to the stomach or parts of the small intestines.Fluids in the stomach then increase the pain of an ulcer.How does a person know he or she has an ulcer?Doctors say most people with ulcers feel a burning pain in their chest or stomach.This pain often is called heart burn.It usually happens before eating or during the night.It causes some people to lose their desire to eat,or they are unable to keep food in their stomachs.Doctors believed that ulcers were caused by unusually strong stomach fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H.Pillorie.H.Pillorie bacteria are what make stomach produce extra stomach fluid.Doctors found that they can kill the bacteria with medicines called antibiotics.Health experts say the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs.They also believe curing ui- cers will reduce the number of people who develop stomach cancer.The number of people with stomach cancer is very high in Japan,Southeast Asia and parts of Africa.
    Doctors say a person is more likely to get an ulcer if his or her family has had one.In fact a person with the family history of ulcers is three times more likely to get one than other peo-ple.There are ways people can protect themselves from developing an ulcer.Doctors say it is more important to reduce the amount of strong fluids in the stomach.To do this,doctors say,people should not smoke cigarettes or drink alcohol.And they say people should reduce tension in their lives.

    Doctors have discovered a cause of ulcers after many years of experiments.
    A:Right
    B:Wrong
    C:Not mentioned

    答案：C
    解析：
    阅读下面这篇短文，短文后列出了七个句子，请根据短文的内容对每个句子作出判断。如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文章中没有提及，请选择C。
    【解析】
    题干意为“过去医生对于胃溃疡是无能为力”。利用题干中的细节信息词/短 语in the past, doctors作为定位线索，在第一段找到相关句：Doctors have been able to help lessen the pain of ulcers.They could not cure them．相关句意为“医生一直能够帮助减少溃疡造成的痛苦。但是他们不能治愈胃溃疡这种疾病”，由此可见在过去医生虽然不能治愈胃溃疡，但也能对这种疾病进行治疗，因此题干陈述的意义与短文内容不一致。该题主要考查对时态意义的理解：相关句使用了现在完成时态，这表明“减少胃溃疡造成的疼痛（即治疗胃溃疡）”是从过去持续到现在的动作，这也就说明在过去就能对胃溃疡进行治疗。
    题干意为“现在医生能成功地治愈胃溃疡” 该句在句意上与上题有关：一个说过去的情况，一个说现在的情况，因此从上一题的相关句的位置往下找该题相关句，同时关注题干中的细节信息词now , doctors，题干中出现的修饰词successfully在查找相关句的过程中也 需要关注，这样在第一段找到相关句：Now doctors have discovered a cause of ulcers.This means they may have found a way to cure people who suffer from the stomach pain．该句意为“现在医生们已经发现了溃疡的一种致病原因。这就意味着他们可能已经找到一种方法来治疗那些遭受到胃痛困扰的人”，由此不难看出题干与该句的内容不一致：题干在肯定地陈述一个事实：能成功治愈胃溃疡；短文说只是可能：“可能找到治疗方法”，即现在治愈胃溃疡只是一种可能（提示：混淆 “可能性”和“事实”是阅读判断题中“错误”这个答案选项常见的出题形式）。
    题干意为“有些人可能在一生中的某个时候遭受胃溃疡这种疾病的困扰”。利用题干中的细节信息词/短语some people, at some time in their life作为定位线索，这样在 第一段中找到该题相关句：Studies show that ten percent of the population（与some people 呼应）will develop an ulcer at some time in their life．该句意为“研究显示10%的人在他们一生中的某个时候可能遭受胃溃疡的困扰”。很明显，这与题干意义一致。
    题干意为“经过多年的实验后医生已经发现了溃疡的一种致病原因”。利用 题干中的细节信息词/短语doctors, a cause of ulcers,after many years of experiments作为定 位线索，在第一段找到涉及到doctor和a cause of ulcers相关的句子：Now doctors have dis-covered a cause of ulcers．该句没有提到many years of experiments“许多年的试验”，而短文中的其他部分也没有出现many years of experiments，由此可见“是否医生们是经过许多年的试验后才发现溃疡的一种致病原因”是无法从短文中了解到的信息，因此题干陈述的信息是短文中未提及的信息（提示：题干中只要有一部分信息是短文中未提及的信息，就可以由此判断题干陈述的信息是短文中未提及的信息）。
    题干意为“医生对胃溃疡的致病原因的理解已经有了变化”。利用题干中的 细节信息词/短语change, doctors's understanding, the cause of stomach ulcer作为定位线 索，这样找到相关句：Doctors believed（与 doctors' understanding呼应）that ulcers were caused（与the cause of stomach ulcer)by unusually strong stomach fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused（与the cause of stom- ach ulcer)by a bacterial organism called Hillico Bactor Pilorie or H.Pillorie．这两个句子提到“医生过去认为溃疡是由胃里超强的液体流动造成的。现在他们发现大多数的胃溃疡是由细菌造成的……”，这两个句子通过陈述医生们过去对溃疡的理解和现在对溃疡的理解来说明医生对溃疡的理解已经有了变化，很明显，题干意义就是对这两个相关句意义的概括（提示：有的题干是对短文中相关句子意义的概括总结）。
    题干意为“胃溃疡会导致胃癌”。利用题干中的细节信息短语stomach cancer 作为定位线索词，这样在第二段的结尾部分找到相关句：They also believe curing ulcers will re- duce the number of people who develop stomach cancer．该句意为“他们认为治愈溃疡能够减少患胃癌的人数”，由此可知胃溃疡是造成胃癌的一个原因，题干陈述的信息与短文内容一致。
    题干意为“喜欢吃辛辣食物的人容易患胃溃疡”。利用题干中的细节信息短语a lot of spicy food作为定位线索，结果发现短文中根本没有谈到spicy food，由此可知短文中根本没有涉及到辛辣食物和胃溃疡之间的关系，因此无法依据短文判断出是否喜欢吃辛辣食物的人容易患胃溃疡，由此判断题干陈述的信息为短文中未提及的信息。

  • 第21题：

    资料：When we see well，we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
    People who are near-sighted can only see things that are very close to their eyes，Everything else seems blurry（=unclear）.Many people who do a lot of work，such as writing，reading and sewing become near-sighted.
    People who are far-sighted suffer from just the opposite problem. They can see things that are far away，but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading，they must get glasses，too.
    Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism. This，too，can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now，however，it is possible to operate on the cataracts and remove them.
    Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself，look at an object out of one eye；Then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.

    The underlined word suffer in the third paragraph probably means______.

    A.feel pain
    B.imagine
    C.are affected with
    D.experience

    答案：A
    解析：
    本题考查的是推理判断。
    【关键词】suffer；in the third paragraph；mean
    【主题句】第3自然段People who are far-sighted suffer from just the opposite problem. They can see things that are far away，but they have difficulty in reading a book unless they hold it at arm’s length. 远视的人遭遇了相反的问题。他们可以看到很远的东西，但是他们看书有困难，除非保持一定的距离，否则很难阅读。
    【解析】本题的问题是“第三段中带下划线的词suffer可能意味着_______”A选项“感到痛苦”；B选项“想象”；C选项“受到影响”；D选项“经历，经验”。根据主题句，远视的人遭遇着相反的问题，故A选项正确。
