练习册系列答案

18．Ever tried taking smart drugs（药） to perform better in exams？They certainly work．Before last summer's exam，a few of my classmates，only out of curiosity，took a large amount of Modafinil，a drug normally used for narcolepsy（嗜眠发作症）．Guess what？While I was feeling sleepy，bored by homework，my classmates were more focused．
Modafinil is a smart drug that gives a user a feeling of staying awake for hours．It also sharpens the mind，improves memory and helps problem-solving．
But it does more than just keeping you awake．It disturbs your mental（神经的） system，making you do what you are doing with all efforts．You just don't want to do anything else but do homework all the time non-stop．
A recent study discovers that healthy people use smart drugs，like Modafinil，to get down to and complete tasks they have been putting off，because these tasks seem more enjoyable when taking these drugs．This might sound like what a stressed（有压力的） student wants．However，the pills have some side-effects．
"At present no evidence shows that these drugs are safe in healthy people，"as a medical expert puts it，"Ordering online，though easy，is a dangerous way to get drugs．You never know what you're actually buying．"
In my experience，Modafinil changes people's behaviour too．Over those weeks my friends became different people-in turn strange，cold．Even eating became"a waste of time"and so did conversation．
A survey found that of those who had tried smart drugs before，92% would do so again．My friends say they'd happily do so without considering the practice a form of cheating．
I admit I was curious-but not enough to try it．Seeing the strange behaviour of other users，I feel a little bit upset and frightened．Modafinil may promise to change your grades，but it might also change the way you act．Don't say you haven't been warned!
66．According to the author，his classmates took Modafinil for the purpose ofB．
A．escaping from reality
B．getting better exam results
C．staying awake
D．leading an active life
67．Taking the smart drug can lead toD．
A．cheating in the exam
B．dropping out of school
C．behaving better than before
D．getting the habit of taking it
68．What does the author think of his classmates'taking the smart drugs？A
A．Worrying．
B．Inspiring．
C．Acceptable．
D．Reasonable．
69．Which statement about Modafinil is wrong？D
A．Modafinil sharpens the mind and helps problem-solving．
B．Modafinil more than just keeps you awake．
C．Modafinil has some side effects．
D．Modafinil is safe in healthy people．
70．The passage is probably written toD．

15．People's _________of life has been greatly improved since the new government was founded．（　　）

2．Nowadays it is a trend in China to buy things looking nice，especially when people decide to buy something as a gift for their friends．Doing so has automatically triggered a rapid development in packaging industry，but also caused a huge waste in our national resources．
A good example is to buy a bag of Chinese tea．The tea itself may cost more than 500CNY but it includes nearly 200CNY，for the package．Does it mean high quality when you buy goods in an attractive case？The answer is"perhaps"．"Perhaps"here means 50% of a chance to buy something really good and the other 50% of the chance is to buy something crap or fake．One of my friends bought a bottle of Maotai for l800CNY，"and he was absolutely embarrassed to find there to be water in it in front of his invited guests．It is crazy．
Things have become so expensive and so well packed that many companies produce fake products，playing the same trick．We should criticize the manufacturers that produce crap and fake goods，but should those companies that charge their customers a large amount of money just for the package be praised？No．As customers，we need to think about the question：why do we have to chase the superficial things when we buy things？Why do we have to buy friends expensive gifts？Are a notebook computer，an iPhone and electronics really something we have to buy as gifts to someone？Can we not change our ways to show our love to our beloved ones just with an item suitable instead of telling them how much it is worth？If we make statistics in our population，it is easy to find out that 99% of the people would express their hatred for bribery and corrupted officials．However，how many of us have ever asked ourselves a question like"What have I done in the past year that has promoted corruptions in our country？"

62．Through the second example in Paragraph 2，the author wants to indicate thatB．
A．buying things looking nice is a good choice
B．things with good package don't necessarily mean good quality
C．some companies charge customers too much money for the package
D．his f'riends are angry to the fake Maotai．
63．Which of the following word is similar to the underlined word"crap"？A
A．rubbishy B．valuable C expensive D rotten
64．Which may be the best choice when we buy something for our beloved ones？B
A．An electronic product．
B．Something best suitable to show our love．
C．An expensive and good-looking gift．
C．A bag of Chinese tea．
65．Which of the following statements is the author probably in favor of？A
A．A great number of people have done many things related to corruption．
B．To choose presents，we should pay much attention to superficial things．
C．There is a minority of people hating bribery．
D．Many companies play different tricks to promote the sales of their fake products．

12．Being a ______ tennis player，Williams wouldn't let anyone or any difficulty stop her．（　　）

19．Each Indian tribe（部落） had a different language．Many Indians never learned any language except their own．Do you know how Indians from different tribes talked to each other？They had two ways to talk without sound．One way was by sign language；the other way by signals．
Sign language is a way of talking by using signs．Indians used sign language when they met strangers．In this way，they could find out whether the stranger was a friend or an enemy．In the Indian sign language，signs were made with the hands．One sign meant"man"．Another meant"horse"．To tell the time of day when something happened，an Indian pointed to the sky．He showed where the sun had been at the time．
Indians usually used signals when they wanted to send messages to someone far away．To make signals，an Indian might use a pony．He might use a blanket．Or he might use smoke，a mirror or fire arrows．
To signal that he had seen many animals，an Indian rode his pony in a large circle．Sometimes the Indian gave a signal like this and then went away to hide．This meant that there was danger．
The blanket signal was visible from far away．An Indian held the corners of a blanket in his hands．Then he began to swing the blanket from side to side in front of him．An Indian could send many different signals with his blanket．
He could also send many signals with a mirror．He usually used the mirror to warn someone of danger．Or he attempted to get the attention of a person far away．But he also used it to send messages in code．Of course，mirrors could be used only when the sun was shining．At night，Indians used fire arrows for signaling．
An Indian also sent signals with smoke．He made a small fire．Then he put grass or green branches on it．He held a blanket over the fire for a minute．When he removed the blanket from the fire，there was a cloud of smoke．The number of clouds of smoke told his message in code．
Now you can see that Indians didn't need to learn each other's language．They could talk to one another by using signals or sign language．
54．From the passage we can infer thatB．
A．Indian language was difficult to learn，so many Indians never learned it
B．among the Indian tribes there was no common spoken language
C．many Indians couldn't communicate with each other
D．Indians talked with each other only in two ways---sign and signal language
55．Which of the following statements is TRUE according to the passage？A
A．One or two clouds of smoke sent different message．
B．In Indian sign language，"man''meant friend and"horse"meant enemy．
C．If an Indian rode his pony in a large circle，it meant there was danger．
D．Signals with smoke could be used to send messages at night．
56．What is the best title of this passage？D
A．Indians'way of life B．Each Indian tribe had its own language
C．How to use signals and sign language D．Talking without sound．

16．Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since．A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water．He can get on a bicycle after many years and still ride away．He can play，catch and hit a ball as well as his son．A mother who has not thought about the words for years can teach her daughter the poem that begins"Twinkle，twinkle，little star"or remember the story of Cinderella or Goldilocks and the Three Bears．
   One explanation is the law of overlearning，which can be stated as follows：Once we have learned something，additional（额外的） learning trials（尝试）increase the length（长度） of time we will remember it．
   In childhood we usually continue to practice such skills as swimming，bicycle riding，and playing baseball long after we have learned them．We continue to listen to and remind ourselves of words such as"Twinkle，twinkle，little star"and childhood tales such as Cinderella and Goldilocks．We not only learn but overlearn．
The multiplication tables（乘法口诀表）are an exception（例外） to the general rule that we forget rather quickly the things that we learn in school，because they are another of the things we overlearn in childhood．
   The law of overlearning explains why cramming（突击学习）for an examination，though it may result in a passing grade，is not a satisfactory way to learn a college course．By cramming，a student may learn the subject well enough to get by on the examination，but he is likely soon to forget almost everything he learned．A little overlearning，on the other hand，is really necessary for one's future development．
32．What is the main idea of paragraph I？C
A．Poem reading is a good way to learn words．
B．Children have a better memory than grown-ups．
C．People remember well what they learned in childhood．
D．Stories for children arc easy to remember．
33．The author explains the law of overlearning byD．
A．presenting research findings
B．using examples
C．making a comparison
D．setting down general rules
34．What does the word"they"in Paragraph 4 refer to？A
A．The multiplication tables．
B．Commonly accepted rules．
C．Things easily forgotten．
D．School subjects．
35．What is the author's opinion on cramming？C
A．It leads to failure in college exams．
B．It's possible to result in poor memory．
C．It's helpful only in a limited way．
D．It increases students'learning interest．

3．What will people die of 100years from now？If you think that is a simple question，you have not been paying attention to the revolution that is taking place in biotechnology（生物科技）．With the help of new medicine，the human body will last a very long time．Death will come mainly from accidents，murder and war．Today's leading killers，such as heart disease，cancer，and aging itself，will become distant memories．
In discussion of technological changes，the Internet gets most of the attention these days．But the change in medicine can be the real technological event of our times．How long can humans live？Human brains were known to decide the final death．Cells are the basic units of all living things，and until recently，scientists were sure that the life of cells could not go much beyond 120years because the basic materials of cells，such as those of brain cells，would not last forever．But the upper limits will be broken by new medicine．Sometime between 2050and 2100，medicine will have advanced to the point at which every 10years or so，people will be able to take medicine to repair their organs．The medicine，made up of the basic building materials of life，will build new brain cells，heart cells，and so on-in much the same way our bodies make new skin cells to take the place of old ones．
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence，but many technical problems still must be cleared up on the way to this wonderful future．
32．According to the passage，human death is now mainly caused byA
A．diseases and aging            B．accidents and war
