9．One day newly wedded Nancy lost her ring while helping to plant potatoes．Friends were called and the field was searched long but in vain（徒劳）．Later，when the potatoes were harvested，everyone looked out for the ring but it remained lost．Another year came round and all the farmers working in the field kept their eyes open．The following year was the same．And year after year，whoever had business in the field always had Nancy's ring in his mind．
Then the farm changed hands but it went no farther than to cousins．So the memory of the lost ring remained alive until thirty-eight years had passed．Then came a spring day when a man was ploughing the field behind a pair of horses．Even after thirty-eight years he still looked out for the ring，and knew just which part of the field Nancy had lost it in．At this time，when he came there，he found it．He picked it up，put it carefully into his pocket，left his horse，and ran all the way down to the village and placed it into Nancy's hand．

8．Here is an astonishing and significant fact：Mental work alone can't make us tired．It sounds absurd．But a few years ago，scientists tried to find out how long the human brain could labor without reaching a stage of fatigue （疲劳）．To the amazement of these scientists，they discovered that blood passing through the brain，when it is active，shows no fatigue at all!If we took a drop of blood from a day laborer，we would find it full of fatigue toxins（毒素） and fatigue products．But if we took blood from the brain of an Albert Einstein，it would show no fatigue toxins at the end of the day．
So far as the brain is concerned，it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning．The brain is totally tireless．So what makes us tired？
Some scientists declare that most of our fatigue comes from our mental and emotional（情绪的） attitudes．One of England's most outstanding scientists，J．A．Hadfield，says，"The greater part of the fatigue from which we suffer is of mental origin．In fact，fatigue of purely physical origin is rare．"Dr．Brill，a famous American scientist，goes even further．He declares，"One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems．"
What kinds of emotions make sitting workers tired？Joy？Satisfaction？No!A feeling of being bored，anger，anxiety，tenseness，worry，a feeling of not being appreciated---those are the emotions that tire sitting workers．Hard work by itself seldom causes fatigue．We get tired because our emotions produce nervousness in the body．
32．What surprised the scientists a few years ago？C
A．Fatigue toxins could hardly be found in a laborer's blood．
B．Albert Einstein didn't feel worn out after a day's work．
C．The brain could work for many hours without fatigue．

B．Unpleasant emotions．
C．Endless tasks．
D．Physical labor．
34．What's the author's attitude towards the scientists'idea？A
A．He agrees with them．
B．He doubts them．
C．He argues against them．
D．He hesitates to accept them．
35．We can infer from the passage that in order to stay energetic，sitting workers need toB．
A．have some good food．
B．enjoy their work
C．exercise regularly
D．discover fatigue toxins．

7．Satellites play big roles in modern life．Some look downward to monitor environmental conditions on Earth．Others look outward in search of major solar flares（耀斑） that can trouble the transmission（传送） of electrical power to homes and businesses．Some spy on our enemies．Others relay communications around the globe．But all of these million-dollar wonders of technology can be knocked out by a collision with space junk---debris （碎片）from satellites and other earthly technology orbiting high above the planet．Now，a teen from Jordan has designed a satellite to chase down space junk，collect it and then deal with it．
Even bits of space junk as small as dots of paint pose a threat，says Dana．That's because this debris orbits our planet at speeds up to some 28，200kilometers per hour．Such high speed explains why tiny paint dots have damaged the windshields of space shuttles so badly that they needed to be replaced．
Researchers have come up with many ideas for getting rid of space junk．Some have suggested vaporizing（蒸发） small bits with lasers．Others have proposed launching satellites to collect the debris．Dana's design falls into this category．
Here's how hers would work：A radar system aboard the satellite would scan and find a piece of space junk．Then，thrusters（推进器）would change the satellite's orbit so that it could chase down the errant object．As the satellite closed in on its prey，cameras would keep it on target．
At the last minute，a door that leads to a container would open．This container needs to be strong so that it doesn't break apart when the satellite swallows the space junk，Dana explains．Finally，when the trash container was full，it would be lowered toward the earth on a kilometer-long cable and its contents released into the upper atmosphere．There，the space junk would harmlessly burn up just like a meteor （流星） does．Meanwhile，her satellite would roll the container back up so that it could collect more trash．
24．What is focused on in the first paragraph？D
A．The types of satellites being categorized into．
B．The tracks of satellites orbiting above the planet．
C．The sources of space junk coming from．
D．The danger that satellites face in space．
25．Why can small pieces of space junk threaten satellites？A
A．They travel at a very high speed．
B．They are difficult to track by satellites．
C．They can blow up into millions of pieces．
D．They are as soft as a ball in the air．
26．The underlined words"the errant object"refer toB．
A．the radar system that scans space junk
B．the space junk that travels in disorder
C．the satellite that doesn't keep its track
D．the camera that can't keep space junk on target
27．According to the Dana's design，space junk in her satelliteC．
A．will be swallowed and stored in its trash bin
B．will be broken apart in the trash container
C．will be destroyed by heat in the upper atmosphere
D．will be transported to the earth through a cable．

6．Praise can change a person．It is true that （61）encouraging（encourage） words can turn our lives around．Praise is really （62）magical（magic）．Perhaps many of us have such experiences．Take myself （63）asan example．I was very naughty in the primary school．Most of the teachers and even my parents were （64）disappointed（disappoint） in me．But it （65）happened（happen） that I once got a very high mark in （66）an examination and the head teacher（67）reported（report） this to my parents．My parents praised me and told neighbors about it．I felt really happy （68）andbecame polite to others．Every time I heard others talk to me about my excellent examination result，I thought to （69）myself（I） that I would work even （70）harder（hard） and make greater progress．Just as Shakespeare said，"Our praises are our wages．"

5．Keeping a diary in English is one of the effective ways to improve our English writing abilities．
（61）Compared（compare） with other forms of writing，it is shorter and takes （62）less time．It can help us to develop the habit of thinking in English．（63）If we persist in this practice，gradually we'll learn how to express ourselves in English．In keeping a diary in English，we certainly run up against many difficulties．In the first place，it often happens （64）that we have trouble finding appropriate words and phrases to give expression to our mind．（65）Secondly （second），there are many idiomatic ways of saying things in Chinese，but it is （66）extremely（extreme）hard for us to put them int o English properly．
As far as I am concerned，my （67）suggestion（suggest） is that we should always have a notebook and a Chinese-English dictionary within easy reach．Whenever something （68）beats （beat） us，we can first put it down in our notebook and then consult our dictionary．We can also turn to our English teacher for help，if necessary．In short，I believe that it is （69）ofgreat use to keep a diary in English for （70）thedevelopment of our writing skills．

4．Many people travel during the holiday season but do not make sure that their houses and homes（61）are protected（protect）．Crimes go up（62）rapidly（rapid） during the winter and summer holiday seasons．Here are some things that you should keep in mind when you go on holiday．
Always give（63）strangers（strange） the feeling that you are at home．Have the snow（64）cleaned（ clean ） off your stairs or out of your driveway during the winter season．You might ask someone to park his/her car in（65）your（you） driveway．
Tell your newspaper deliverer that you are not at home．（66）Having（have） a pile of newspapers and other mail on your doorsteps tells people that you are not at home，so you could also have a neighbor（67）ora relative get your mail every day．
Fix a timer（定时器） in some of your rooms（68）that/whichturns lights on and （69）offduring different time of the day．Some TVs also come with a timer that you could set to be turned on during certain time．Have motion（运动） sensitive lights outside your house that keep thieves away （70）when/whileyou are not at home．

3．Dear Amy，
My computer was broken so I couldn't read your two e-mails until today．I'm so sorry to hear about your problems，61．but I'm glad you're feeling better and are recovering．I'm amazed that in China someone's liver matched yours!62．这真是件令人感动的事 a stranger who donated part of his liver to a girl he doesn't even know!You are right．We shouldn't be embarrassed about our weight．63．I think you look great as you are，and you're a wonderful person．I know that the pressure to stay slim is a problem，especially for an actress．However，your mother knows best：64．没有什么比健康更重要．
65．It's the same in China---many people，some of whom are not overweight at all，are always going on diets or taking weight-loss bills．I hope they can learn from your story．
Love，
Zhou Line
61．但令我高兴的是，你现在感觉好多了
62．This is really a touching/moving story．
63．我觉得你目前的这个样子看上去就很好
64．nothing is more important than health
65．中国的情况也是如此．

20．Most people around the world are right-handed．This also seems to be true in history．In 1799，scientists studied works of art made at different times from 1，500B．C．to the 1950s．Most of the people shown in these works are right-handed，so the scientists guessed that right-handedness has always been common through history．Today，only about 10% to 15% of the world's population is left-handed．
Why are there more right-handed people than left-handed ones？Scientists now know that a person's two hands each have their own jobs．For most people，the left hand is used to find things or hold things．The right hand is used to work with things．This is because of the different work of the two sides of the brain．The right side of the brain，which makes a person's hands and eyes work together，controls the left hand．The left-side of the brain，which controls the right hand，is the centre for thinking and doing problems．These findings show that more artists should be left-handed，and studies have found that left-handedness is twice as common among artists as among people in other jobs．
No one really knows what makes a person become right-handed instead of left-handed．Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born．However，this doesn't happen to everyone，so scientists guess there must be another reason why people become left-handed．One idea is that people usually get right-handed from their parents．If a person does not receive the gene（基因） for right-handedness，he/she may become either right-handed or left-handed according to the chance and the people they work or live with．
Though right-handedness is more common than left-handedness，people no longer think left-handed people are strange or unusual．A long time ago，left-handed children were made to use their right hands like other children，but today they don't have to．
