Learn About Noble Gases（惰性气体）

1 Have you ever ridden on a balloon?Many tourist spots offer balloon rides in order for people to see
the beauty of a place from above.A balloon contains a noble gas called helium（氦）.Formerly,balloons con-
tamned hydrogen but hydrogen is very flammable and dangerous when uncontrolled.Therefore,people shifted
to helium,which is safer. Helium is safe because it has the properties of the noble gases.
2 People once believed that noble gases couldn't chemically react at all.For this reason,they were
called inert gases(隋性气体）.They were also listed under Group 0 in the old periodic table because scien-
tists believed that the gases have zero valence（价）electrons in their outer shell.This was later proven to be
untrue when some noble gas compounds were discovered.
3 The gases are elements,which share similar properties.These properties include being monoatomic,
colorless,odorless,being able to conduct electricity,and having low chemical reactivity.Noble gases
include helium,neon,argon,krypton,xenon and radon.These are all found in Group 18,in the right most
column of the periodic table.If you look at the periodic table,you will notice that these elements are the only
ones which do not have a charge. Helium has the lowest molecular（分子的）weight while radon is the
heaviest.
4 Remember that chemical reactions occur because atoms have valence electrons,which are electrons
in their outer shell.When the outer shell is"unfilled"or the required number of electrons is not yet com-
plete,the atom is more reactive.Noble gases have a full outer shell,meaning that they have complete elec-
trons in their outer shell.This complete number varies.For instance,the outer shell of helium has 2 valence
electrons while the outer shell of xenon has 8 electrons.Nowadays,there remains to be a few noble gases
because of the low chemical reactivity of these said gases.
5 because of their properties,noble gases have many important applications.They are widely used in
medicine and industries. For instance , liquid helium is used for superconducting magnets（磁体）.These
magnets are very important in physics and medicine.When a doctor suspects that a person's brain has been
damaged,he might request for Magnetic Resonance Imaging(MRI).MRI allows the doctor to"see"the
brain,without operating on the patient.

The required number of electrons in noble gases' outer shell is __________.
A:reactive
B:lightest
C:important
D:complete
E:flammable
F:unnecessary

4.A group of 30 employees was working in a software company. This was a young and energetic team with keen enthusiasm and desire to learn and grow.One day the team was called to play a game in a hall. As they entered the hail, they found the hall decorated beautifully with colourful decorative papers and balloons. It was more like a kid’s play area than a corporate meeting hall. Everyone was surprised and gazed at each other. Also, there was a huge box of balloons placed at the centre of the hall.The team leader asked everyone to pick a balloon from the box an blow it. Then he asked them to write their names on their balloon carefully so that the balloons didn’t blow up.Those who failed were ruled out of the game. Altogether 25 employees were qualified for the next level. All the balloons were collected and then put into a room.The team leader asked the 25 employees to go to the room and pick the balloon with their own name on it. All 25 employees reached the room. While they were in a rush to find the respective balloons, they tried not to burst the balloons. It was almost 15 minutes and no one was able to find the balloon carrying his own name.The team was told that the second level of the game was over.Now it was the third and final level. The employees were asked to pick any balloon in the room and give it to the person named on the balloon. Within a couple of minutes ail balloons reacted the hands of the respective employee.The team leader announced: This is called real solutions to the problems.21. When the employees were called to play a game, they ____.A.knew what game they were going to playB.laughed at the idea of adults playing a gameC.had no idea what they were asked to doD.looked forward to playing a kid’s gameAt the first level of the game, each employee was asked to ____.A.blow a balloon and write his name on itB.put his name on a balloon and blow itC.pick up a balloon with his name on itD.write his name on a floating balloonWhat does the software company aim to do?A.Encourage its employees to learn from each otherB.Train its employees to face all kinds of challengesC.Select the employees most suitable for their jobsD.Teach its employees the importance of teamworkHow many employees failed the second level of the game?A.30B.25C.15D.5The key to success at the third level of the game lies in ____.A.thinking positivelyB.helping each otherC.believing in oneselfD.increasing efficiency请帮忙给出每个问题的正确答案和分析，谢谢！

    Have you ever stopped to think why many people are complaining about all the pressure in life? (翻译)


    参考答案：你是否认真思考过，为什么那么多人都在抱怨生活中的种种压力?

  • 第2题：

    A

    Societies all over the world name places in similar ways. Quite often there is no official naming ceremony but places tend to be called names as points of reference by people. Then an organized body steps in and gives the place a name. Frequently it happens that a place has two names: One is named by the people and the other by the government. As in many areas, old habits died hard, and the place continues to be called by its unofficial name long after the meaning is lost.

    Many roads and places in Singapore(新加坡) are named in order that the pioneers will be remembered by future generations. Thus we have names such as Stamford Road and Raffles Place. This is in keeping with traditions in many countries ---- in both the West and the East.

    Another way of naming places is naming them after other places. Perhaps they were named to promote friendships between the two places or it could be that the people who used to live there were originally from the places that the roads were named after. The mystery is clearer when we see some of the roads named in former British bases. If you step into Selector Airbase you will see Piccadilly Circus ---- obviously named by some homesick Royal Air Force personnel.

    Some places were named after the activities that used to go on at those places. Bras Basah Road is an interesting example, “Base Basah” means “wet rice” in Malay(马来语). Now why would anyone want to name a road “Wet Rice Road”? The reason is simple. During the pioneering days, wet rice was laid out to dry along this road.

    A few roads in Singapore are named by their shapes. There is “Circular Road” for one. Other roads may have part of their names to describe their shapes, like “Paya Lebar Crescent”. This road is called a crescent(月牙) because it begins on the main road, makes a crescent and comes back to join the main road again.

    36. We learn from Paragraph 1 that _____.

    A. the government is usually the first to name a place

    B. many places tend to have more than one name

    C. a ceremony will be held when a place is named

    D. people prefer the place names given by the government

    Rockets in the Sky
    If someone asked you,"What color is the sky?"I expect that you would answer,"Blue."I am afraid that you would be wrong.The sky has no color.When we see blue,we are looking at blue sunlight.The sunlight is shining on little bits of dust in the air.
    We know that there is air all around the world.We could not breathe without air.Airplanes could not fly without air.They need air to lift their wings.Airplanes cannot fly very high because as they go higher the air gets thinner.If we go far enough away from the earth,we find there is no air.
    What is the sky?The sky is space.In this space there is nothing except the sun,the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space.They have looked at them through telescopes and in this way they have found out a great deal.The moon is about 384 ,000 kilometers away from the earth.An airplane cann't fly to the moon but there is a thing that can fly even when there is no air. This is rocket.
    I am sure that you are asking,"How does a rocket fly?"If you want to know,get a balloon and then blow it up until it is quite big.Do not tie up the neck of the balloon.Let go!The balloon will fly off through the air very quickly.The air inside the balloon tries to get out.It rushes out through the neck of the balloon and this pushes the balloon through the air.It does not need wings like an airplane.
    This is how a rocket works.It is not made of rubber（橡胶）like a balloon,of course.It is made of metal. The metal must not be heavy but it must be very strong.There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket,the rocket is pushed up into the air.
    Rockets can fly far out into space.Rockets with men inside them have already reached the moon.Several rockets,without men inside them,have been sent to other worlds much farther away.One day rockets may be able to go anywhere in the space.

    Which of the following statements about a rocket is NOT true?
    A:It can fly when there is no air.
    B:It can fly without wings.
    C:It is made of strong metal.
    D:It is propelled by burning gas inside it.

    答案：D
    解析：
    根据第一段第四句可知，天空没有颜色。
    根据第二段第五句“Airplanes cannot fly very high because as they go higher the air gets thinner.”可知，由于位置越高，空气越稀薄，飞机飞不了太高。
    根据第五段可知，火箭飞行的原理与没扎口的膨胀的气球相似。
    根据第六段最后一句“When it rushes out of the end of the rocket , the rocket is pushed upinto the air.”可知，火箭是由热气流高速向后喷出所产生的反作用力来推动的，而不是由内部燃烧的气体推动的。
    根据第六段最后一句可知，当热气从火箭尾部冲出时，火箭被送人空中。C项中的“itsbottom”是第六段最后一句中的“the end of the rocket”的同义转换。

    Learn About Noble Gases（惰性气体）

    1 Have you ever ridden on a balloon?Many tourist spots offer balloon rides in order for people to see
    the beauty of a place from above.A balloon contains a noble gas called helium（氦）.Formerly,balloons con-
    tamned hydrogen but hydrogen is very flammable and dangerous when uncontrolled.Therefore,people shifted
    to helium,which is safer. Helium is safe because it has the properties of the noble gases.
    2 People once believed that noble gases couldn't chemically react at all.For this reason,they were
    called inert gases（惰性气体）.They were also listed under Group 0 in the old periodic table because scien-
    tists believed that the gases have zero valence（价）electrons in their outer shell.This was later proven to be
    untrue when some noble gas compounds were discovered.
    3 The gases are elements,which share similar properties.These properties include being monoatomic,
    colorless,odorless,being able to conduct electricity,and having low chemical reactivity.Noble gases
    include helium,neon,argon,krypton,xenon and radon.These are all found in Group 18,in the right most
    column of the periodic table.If you look at the periodic table,you will notice that these elements are the only
    ones which do not have a charge. Helium has the lowest molecular（分子的）weight while radon is the
    heaviest.
    4 Remember that chemical reactions occur because atoms have valence electrons,which are electrons
    in their outer shell.When the outer shell is"unfilled"or the required number of electrons is not yet corn-
    plete,the atom is more reactive.Noble gases have a full outer shell,meaning that they have complete elec-
    trons in their outer shell.This complete number varies.For instance,the outer shell of helium has 2 valence
    electrons while the outer shell of xenon has 8 electrons.Nowadays,there remains to be a few noble gases
    because of the low chemical reactivity of these said gases.
    5 because of their properties,noble gases have many important applications.They are widely used in
    medicine and industries. For instance , liquid helium is used for superconducting magnets（磁体）.These
    magnets are very important in physics and medicine.When a doctor suspects that a person's brain has been
    damaged,he might request for Magnetic Resonance Imaging(MRI).MRI allows the doctor to"see"the
    brain,without operating on the patient.

    Noble gases are not very chemically____________.
    A:complete
    B:reactive
    C:unnecessary
    D:flammable
    E:important
    F: lightest

    答案：B

    Rockets in the Sky
    If someone asked you,"What color is the sky?"I expect that you would answer,"Blue."I am afraid that you would be wrong.The sky has no color.When we see blue,we are looking at blue sunlight.The sunlight is shining on little bits of dust in the air.
    We know that there is air all around the world.We could not breathe without air.Airplanes could not fly without air.They need air to lift their wings.Airplanes cannot fly very high because as they go higher the air gets thinner.If we go far enough away from the earth,we find there is no air.
    What is the sky?The sky is space.In this space there is nothing except the sun,the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space.They have looked at them through telescopes and in this way they have found out a great deal.The moon is about 384 ,000 kilometers away from the earth.An airplane cann't fly to the moon but there is a thing that can fly even when there is no air. This is rocket.
    I am sure that you are asking,"How does a rocket fly?"If you want to know,get a balloon and then blow it up until it is quite big.Do not tie up the neck of the balloon.Let go!The balloon will fly off through the air very quickly.The air inside the balloon tries to get out.It rushes out through the neck of the balloon and this pushes the balloon through the air.It does not need wings like an airplane.
    This is how a rocket works.It is not made of rubber（橡胶）like a balloon,of course.It is made of metal. The metal must not be heavy but it must be very strong.There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket,the rocket is pushed up into the air.
    Rockets can fly far out into space.Rockets with men inside them have already reached the moon.Several rockets,without men inside them,have been sent to other worlds much farther away.One day rockets may be able to go anywhere in the space.

    When an airplane flies too high,______.
    A:the air will be too thin to support its wings
    B:the air will become thicker
    C:the air will exert pressure on it
    D:the air will disappear in no time

    答案：A
    解析：
    根据第一段第四句可知，天空没有颜色。
    根据第二段第五句“Airplanes cannot fly very high because as they go higher the air gets thinner.”可知，由于位置越高，空气越稀薄，飞机飞不了太高。
    根据第五段可知，火箭飞行的原理与没扎口的膨胀的气球相似。
    根据第六段最后一句“When it rushes out of the end of the rocket , the rocket is pushed upinto the air.”可知，火箭是由热气流高速向后喷出所产生的反作用力来推动的，而不是由内部燃烧的气体推动的。
    根据第六段最后一句可知，当热气从火箭尾部冲出时，火箭被送人空中。C项中的“itsbottom”是第六段最后一句中的“the end of the rocket”的同义转换。
