     Weather changes when the temperature and the amount of water in the atmosphere change. We can
see and feel water coming from the atmosphere when we have rain. But the water must somehow get
back to the atmosphere. Meteorologists call this the water cycle.
     There are many stages in the water cycle. Rain falls when water vapour in clouds condenses(冷却成
液体). Drops of water form and fall to the ground. The water soaks into the ground and feeds streams
and rivers. A lot of rain falls into the sea. The heat of the sun evaporates some of the water in the ground
and in the rivers, lakes and the sea. It changes the liquid water into water vapour. The vapour rises onto
the air. Water vapour is normally invisible. On a very damp or humid day, however, you can sometimes
see water vapour rising from a puddle or pond in a mist above the water. Water vapour also gets into the
air from living things. Trees and other plants take in water through their roots and give off water vapour
from their leaves.  People and land animals drink water and breathe out water vapour. In all these ways
the water returns to the air. There it gathers to form clouds and condenses to form rain. The rain falls to
earth, and the cycle starts again. It contains even if snow or hail fall instead because both eventually melt
and form water. The amount of water vapour is more in the air tropics than in the cold polar regions.

1. What is the main idea of the passage?

A. Water cycle.                    
B. Water vapour.
C. How rain forms.                  
D. Water, vapour, rain.

2. How many ways of the water returning to the air are discussed in the text?

A. Three    
B. Four    
C. Five      
D. Six

3. Whether water vapour can be seen or not depends on_____.

A. how much water is evaporated
B. how good your eyes are
C. in which way water is evaporated
D. climate or weather

4. From the passage, we get to know_____.

A. there is more water vapour in the air tropics than in cold polar regions
B. there is more water vapour in the air in cold polar region than in the tropics
C. it gets more rain in the tropics than in cold polar regions because there is less vapor
D. the amount of water vapour in the air depends on how often it rains

       It’s true that teens don’t get enough sleep，but changing the school starting time would have a chaoticeffect and throw everyone off balance.
       Scientists have shown that teens are more active later at night than children and adults，so most
teens areprobably staying up later for whatever reasons.“The researchers measured the presence of the
sleeppromoting hormone (荷尔蒙) in teenagers’ saliva (唾液) at different time of the day.They learned
that the hormone levels rise later at night than they do in children and adults-and remain at a higher level
later in the morning.Measuring the hormone in the saliva is a good way to show that most teens have
sleep problems，but changing school schedules isn’t the best way to fix this.Most people arguing against
changing school schedules would say that it would only cause teens to stay up and wake up later，thus
leaving them with the same problem.
      The biggest problem schools would come across from changing their schedules would be the after
school and job conflicts students and teachers would meet.“Teachers reported that students were more
alert，and research showed that afterschool sports and jobs would suffer.Students in that area might have been able to deal with less time for jobs and sports somehow，but some of them have practice and earlier plans that would become conflicted if this change were to occur.Most students rarely have time to play a
sport and do homework before 9 or 10 o’clock.Opening schools later may have worked for some areas，but the reality is often very different.

1．The meaning of the underlined word “chaotic”in the 1st paragraph is close to________.

A．positive 
B．apparent
C．negative 
D．ambiguous

2．Most teens have sleep problems because________.

A．they are more active than children and adults
B．school work takes up most of their time
C．their hormone levels are higher later at night
D．they probably like staying up for no reason

3．Which of the following is TRUE according to the passage?

A．There are many conflicts between students and teachers.
B．Some of the teachers have practice and earlier plans.
C．Most students are able to do sport and homework before 9?00.
D．Ways to solve students’ sleep problem vary from area to area.

4．The passage mainly develops by________.

A．giving reasons  
B．showing examples
C．comparing facts 
D．offering solutions

     Compared to adults, children seem to be moving constantly. So it's no surprise that most parents
who are quizzed about their child's physical activity level describe their children as fairly active. But a
new study of nearly 2000 British school children suggests that many parents overestimate the amount
of physical activity their children are really getting.
     The researchers equipped 1892 British school children, ages 9 and 10, with accelerometers that
measure all physical  activity  during  a  given  time  period.  The research, known as the Speedy study
collected the exercise data from children at  92  schools  in  Norfolk, England, between April and July
2007.
     A child was regarded inactive if he or she recorded less than an hour a day of physical activity.
Although the majority of children studied were getting enough physical activity, a_sizable_minority_of
_children_were_not. Overall,39 percent of girls and 18 percent of boys studied were getting less than
an hour of physical activity each day.
     But if you asked the parents of the inactive children to describe their child's activity level, the vast
majority-80 percent-described their children as fairly or very physically active, according to the findings
published in the American Journal of Preventive Medicine. Interestingly, the children themselves had
more awareness about their lack of physical activity. Overall, 40 percent of children overestimated their
physical activity.
     But it wasn't the parents of overweight children who were most likely to guess wrong about physical
activity levels. The parents who were most out of touch about their child's physical fitness were more
likely to  have children who were slim. Parents of girls were also more  likely  to  overestimate  physical
  activity.  The  researchers noted that parents should be educated about the importance of physical
activity for children even if the child is not overweight.
    “Parents of slim children appear to assume that  their children are adequately active.”the study
authors  reported. “Increasing awareness regarding health benefits of physical activity beyond weight
control might  help have a correct idea of physical activity levels and encourage behavior change.”

1. According to the Speedy study, what kind of children   can be judged physically inactive?

A. Slim children.
B. Children with less than an hour a day of physical activity.
C. Overweight children.
D. Children out of touch with their parents for a long time.

2. What does the writer probably mean by saying “a sizable minority of children were not”in Paragraph 3?

A. The amount of children's physical activity is far from the writer's satisfaction.
B. Only a small number of children were not getting enough physical activity.
C. A small number of children didn't overestimate their physical activity.
D. The minority of children were not studied at all.

4. The passage is intended to________.

A. encourage parents to fairly judge their children's physical activity levels
B. persuade parents to keep an eye on their children's weight
C. urge children to wear accelerometers during exercise
D. advise parents to keep in touch with their children

     It is difficult to imagine what life will be like without memory．The meanings of thousands of
everyday perceptions(感觉、知觉), the bases for the decisions we make, and the roots of our
habits and skills are to be found in our past experiences, which are brought into the present by
memory．
     Memory can be defined as the capacity to keep information available for later use．It includes
not only "remembering" things like arithmetic or historical facts, but also involves any change in
the way an animal typically behaves．Memory is involved when a rat gives up eating grain
because he has sniffed something suspicious in the grain pile．Memory is also involved when
a six-year-old child learns to swing a baseball bat．
     Memory exists not only in humans and animals but also in some physical objects and
machines．Computers, for example, contain devices from storing data for later use．It is
interesting to compare the memory-storage capacity of a computer with that of a human being．
The instant-access memory of a large computer may hold up to 100,000 "words"-ready for
instant use．An average U．S．teenager probably recognizes the meaning of about 100,000
words of English．However, this is but a fraction(部分、片断) of the total amount of
information which the teenager has stored．Consider, for example, the number of faces and
places that the teenager can recognize on sight．
     The use of words is the advanced problem-solving intelligence of human beings．A large
part of a person's memory is in terms of words and combinations of words．
1．According to the passage, memory is considered to be ________．
A．the basis for decision making and problem solving
B．an ability to store experiences of future use
C．an intelligence typically possessed by human beings
D．the data mainly consisting of words and combinations of words
2．The comparison made between the memory capacity of a large computer and that of a human being shows that ________．
A．the computer's memory has a little bigger capacity than a teenager's
B．the computer's memory capacity is much smaller than an adult human being's
C．the computer's memory's capacity is much smaller even than a teenager's
D．both A and B
3．The whole passage implies that _______．
A．only human beings have problem-solving intelligence
B．a person's memory is different from a computer's in every aspect
C．animals are able to solve only very simple problems
D．animals solve problems by instincts rather than intelligence
4．The topic of the passage is __________．
A．What would life be like without memory?
B．Memory is of vital importance to life．
C．How is a person's memory different from an animal's or a computer's?
D．What is contained in memory?

     The common cold is the world’s most widespread illness, which is plagues(疫病) that flesh receives.
     The most widespread fallacy(谬误) of all is that colds are caused by cold. They are not. They are
caused by viruses passing on from person to person. You catch a cold by coming into contact, directly
or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect
the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have
reported being free from colds until coming into contact again with infected people from the outside
world by way of packages and mail dropped from airplanes.
     During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet,
showed no increased tendency to catch colds.
     In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集
中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold
Research Unit in England, volunteers took part in Experiments in which they gave themselves to the
discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing
suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room.
Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the
volunteers came down with a cold unless a cold virus was actually dropped in his nose.
      If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the
winter？Despite the most pains-taking research, no one has yet found the answer. One explanation
offered by scientists is that people tend to stay together indoors more in cold weather than at other times,
and this makes it easier for cold viruses to be passed on.
     No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as
aspirin, but all they do is relieve the symptoms.

1. The writer offered _______ examples to support his argument.

A. 4
B. 5
C. 6
D. 3

2. Which of the following does not agree with the chosen passage?

A. The Eskimos do not suffer from colds all the time.
B. Colds are not caused by cold.
C. People suffer from colds just because they like to stay indoors.
D. A person may catch a cold by touching someone who already has one.

3. Arctic explorers may catch colds when _______.

A. they are working in the isolated arctic regions
B. they are writing reports in terribly cold weather
C. they are free from work in the isolated arctic regions
D. they are coming into touch again with the outside world

4. Volunteers taking part in the experiments in the Common Cold Research Unit _______.

A. suffered a lot  
B. never caught colds
C. often caught colds
D. became very strong

5. The passage mainly discusses _______.

A. the experiments on the common cold
B. the fallacy about the common cold
C. the reason and the way people catch colds
D. the continued spread of common colds

     In a few years, you might be able to speak Chinese,Korean,Japanese,French,and English-andall at the
same time. This sounds incredible,but Alex Waibel,a computer science professor at US's Car-negie
Mellon University (CMU) and Germany's University of Karlsruhe,announced last week that it may soon
be reality. He and his team have invented software and hardware that could make it far easier forpeople
who speak different languages to understand each other.
     One application,called Lecture Translation,can easily translate a speech from one language into
an-other. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Us-ers also have to be trained how to use the programme.
     Another machine can send translations of a speech to different listeners depending on what
languagethey speak. "It is like having a simultaneous translator right next to you but without disturbing the
person next to you,"Waibel said
     Prefer to read? So- called Translation Glasses transcribe(转录) the translations on a tiny
liquid-crystal display(LCD) screen.
     Then there's the Muscle Translator. Electrodes capture the electrical signals from facial muscle
movements made naturally when a person is mouthing words. The signals are then translated into speech.
The electrodes could be replaced with wireless chips implanted in a person's face,according to
research-ers.
     During a demonstration held last Thursday in CMU's Pittsburgh campus,a Chinese student named
Sang Jun had 11 tiny electrodes attached to the muscles of his cheeks,neck and throat. Then he
mouthed-without speaking aloud- a few words in Mandarin (普通话) to the audience. A few seconds
later,the phrase was displayed on a computer screen and spoken out by the computer in English and
Spanish: "Let me introduce our new prototype."
     This particular instrument,when fully developed,might allow anyone to speak in any number of
lan-guages or,as Waibel put it,"to switch your mouth to a foreign language". "The idea behind the
universi-ty's prototypes is to create'good enough' bridges for cross- cultural exchanges that are
becoming more common in the world,"Waibel said.
     With spontaneous(自发的) translators, foreign drivers in Germany could listen to traffic warnings on
the radio; tourists in China could read all the signs and talk with local people;leaders of different
coun-tries could have secret talks without any interpreters there.
1.What can't be learned from the text?
A.The spontaneous translators will help us a lot.
B. There is no Muscle Translator in the world now.
C. Muscle Translators can translate what you think into speech if you just move your mouth.
D. A lecture translation can translate what you said into other languages easily.
2. What does the underlined word mean?
A. happening at at the same time.          
B. happening by itself.
C. similar in size.                     
D. Similar in quality.
3.What's the final destination of inventing the language translators?
A. To make cultural exchanges between different countries easier.
B. To help students learn foreign languages more easily.
C. To make people live in foreign countries more comfortably.
D. To help people learn more foreign languages in the future.
4. What can be inferred from the seventh paragraph?
A. The translator is so good that it can translate any language into the very language you need.
B. The translator is becoming more and more common in the world as a bridge.
C. With the help of the translator,you only need to open your mouth when you want to say
     something without saying the exact words at all.
D.The translator needs to be improved before being put into market.
5. Where can we probably find this passage?
A. A newspaper.                          
B. A magazine on science.
C. A fairy tale.                            
D. A scientific fantasy book.
     What are you doing right now? Yes, you are reading this page. That also means you're moving your
eyes. You're thinking. You're breathing. You're listening. Possibly you're shifting(变换) positions. You're
also feeling things—this book, your chair, emotions. What lets you do all these things at the same time?
Your brain.
     Your brain is the control center of your body and mind. Without your brainyou can't do anything. Your brain has more than 100 billion nerve(神经) cells. Each nerve cell makes from 1,000 to 10,000
connections with other nerve cells. The nerve cells send impulses back and forth in your brain and to and
from every part of your body. After you reach the age of 20, though, your brain cells start to die. This is
common. However, if you suffer an illness, or injury, even more nerve cells die in your brain. When a
nerve cell dies, the thousands of connections it made with other nerve cells are lost.
     Until recently, scientists believed that the brain did not replace its dead cells. New studies, however,
prove not. Scientists have found new nerve cells in a part of the brain called the hippocampus(海马区).
The hippocampus helps the brain form memories from new experiences.
     The discovery of these new nerve cells is not a cure for anything yet. It gives hope, however, of a cure
for brain damage from such things as epilepsy(癫痫病), Lou Gehrig's disease, car accidents, and strokes. Someday scientists might be able to use the new cells to replace damaged brain cells. Such a cure,
however, may take about ten years to develop. So at the same time, use your head—protect it!
2. Nerve cells in the brain______.
A. send massages to every part of the body
B. make connections only to other cells in the brain
C. can cure Lou Gehrig's disease
D. are a person's memory
2. The last sentence of the passage suggests that people______.
A. should use their head by carefully thinking through situations
B. should be careful not to injure their brains
C. have a skull (头盖骨) that provides all the protection needed by the brain
D. would see a quick cure for brain disease
3. The author explains what the hippocampus is by ______.
A. telling its history
B. comparing it to other parts of the brain
C. telling how it got its name
D. explaining what it does
