12．TV advertisements often tell people to drink more．Drink makers are using some famous sportsmen to support their so-called power and energy drinks，claiming they are all needed．（36）D
Water is essential for human health．However，when you neglect your sense of thirst and manage to take in several glasses of water a day just because you have been told that doing so is good for your health，you actually put unnecessary burdens on your body in two major ways．（37）F Since your blood volume exists within a closed system，increasing your blood volume on a regular basis puts unnecessary burden on your heart and blood vessels．Drowning your system with more water is one of many potential causes of inner damage．Your kidneys will have to work overtime，and they must separate extra water out of your circulatory system．（38）A
The information is particularly important for parents to pass on to their children．So how much water should you drink to best support your health？Some people suggest that you should pay more attention to your diet．It is practicable to get water from liquids or whole foods that are rich in it when you do find yourself in need of water．（39）C If you do not use much or any salt，your need for drinking water goes down even further．
The best guidance I can provide on this issue is to follow your sense of thirst．（40）B They can almost always realize that they are indeed thirsty，if you ask such people if they are thirsty and would like a piece of fruit or a glass of water．Please share this article with family and friends，as many people are regularly misinformed on this topic by mainstream media．

A．If not，your health will be in bad condition．
B．Most people are easy to ignore a dry mouth．
C．By doing so，you may not need to drink much water at all．
D．They then go on to claim these drinks are better for you than water．
E．They help you prevent kidney damage and increase concentration levels．
F．Taking in more water than you need can increase your total blood volume．
G．They will believe that thirst is not a reliable indicator of how much water they need．

16．The defeat of Lee Sedol，the world's strongest Go （圍棋） player，by a Google artificial intelligence （AI） program，looks like another milestone towards a world where computers can do almost anything a human can．It is not．There are uncountable things that only a human can do，and that no computer seems close to．The problem is that the purely human things are not economically useful to anyone．The things that computers can be taught to do are by contrast economically fantastic．But even the most powerful programs are not human，just as a shovel （鏟車）．They have no feelings．What they have is power，but this power is growing at a rate that should frighten us a ll．
It might be less frightening if computers were truly intelligent，but even the most powerful networks are less human than monstrous Martians （火星人）．Their power will be used to make money for the firms that finance their development，and then for others quick and clever enough to take advantage of the new world．It is far more likely that they will increase inequality and still further remove the middle classes as we move towards an hourglass （以金錢來衡量的） society in which everyone is either very rich or very poor and likely indebted．
One of the ill effects of the spread of more intelligent computer networks is，at the same time，the spread of what might be called artificial stupidity．If AI is employed largely to replace unskilled labour，it is most productive when labour is kept unskilled or redefined that way．So much of the work in service industries is now simplified until it might be automated （自動化）．And robots will never need pensions．AI is slowly reducing skilled work，like some forms of medical diagnosis （診斷），at the same time，as older doctors complain that the traditional human skills of diagnosis are falling out of medical training．The belief that everything worthwhile can be measured and then managed is far more damaging to humanity than the threat of artificial intelligence on its own．
But no victory in complicated Go games can bring us closer to truly human-like computers．
62．By mentioning the defeat of Lee Sedol，the author intends to tell us thatC．
A．comput ers can completely replace humans in everything
B．humans are of no practical economic values to the society
C．the power of computers is growing at a frightening rate
D．AI programs can not compare with humans economically  
63．We can learn from Paragraph 2 that the power of computers willD．
A．improve the quality of human life
B．promote equality at work places
C．make contributions to human development
D．widen the gap between the rich and the poor
64．What does"artificial stupidity"in Paragragh 3 mean？B
A．Unskilled workers become stupid．
B．AI discourages skilled work．
C．Computers don't need pensions．
D．AI is ruining medical training．
65．What is the author's attitude towards the future of artificial intelligence？C
A．Optimistic．B．Supportive．C．Sceptical．D．Cautious．

7．Ever since Canadian psychiatrist Michael R．Phillips，who works in China，released his report saying China's suicide rate from 1995to 1999reached 0.023percent，the country has been ranked among those with the highest suicide rates in the world．But Jing Jun，a professor of sociology in Tsinghua University，challenges that view and presents the true picture through his nationwide research．
Jing and his students took one year to set up the first national database on suicide rate to grasp the overall trend of suicides in China．They collected data from the Health Statistics Annuals of the World Health Organization （sample size 10million），and the country's Health Statistics Annuals （which cover 100million people）．The database covers 23years，from 1987to 2009．Jing calculates the suicide rate in China based on these data．Though the suicide rate was comparatively high in the early years，his study shows it has dropped in recent years，as opposed to the ascending trend in the rest of the world．
According to Jing's calculation，China's suicide rate had dropped to about 0.01percent in 2004．In 2009，the figure dropped further to 0.007percent，which is rather low compared with the global rate of 0.016percent．Even if the"missing"suicides were added，China's suicide rate in 2009would still be below 0.008percent．
Jing has found that one of the main reasons why the suicide rate has dropped was the steady and big decline in the number of suicides committed by rural women．In the early years，researchers generally agreed that the suicide rate among Chinese women was higher than among men，which is pretty rare in the rest the world．But the suicide rate among Chinese women，especially in rural areas，has declined remarkably in recent years．In fact，it is almost equal to that of Chinese men．
As a sociologist，Jing regards suicide as a social issue，and believes improvement of social policies will reduce the suicide rate even further．More people's lives can be saved if the authorities adjust to social environment for the better，he concludes．

41．From Jing's search，we can seeC．
A．China has been ranked among those with the highest suicide rates in the world
B．in the rest of the world suicide rate has been rising quickly in the last few years
C．different from Michael R．Philip's idea，the trend of suicides in China is declining
D．the suicide rate among Chinese women is lower than that of men
42．The data in Para.2is mainly to prove thatA．
A．the result from Jing's research is believable
B．Jing's research is more complicated than Michael R．Phillip's
C．Jing has made great efforts to make the research
D．China's suicide rate was comparatively low all the time
43．Why has the suicide rate in China dropped steadily according to Jing Jun？C
A．Because the life level of Chinese people has improved a lot．
B．Because China's government has adopted measures to reduce the suicide rate．
C．Because the number of Chinese women who commit suicide has declined．
D．Because the world environment affects the suicide rate in China．
44．In Jing's opinion，what should be done to reduce the suicide？B
A．Pay more attention to rural women．
B．Continue to improve social environment．
C．Set up more mental health centers．
D．Make policies to prevent suicides．
45．We can infer that the text isB．
A．a(chǎn) news report   
B．a(chǎn) research report
C．a(chǎn) description of suicides  
D．a(chǎn)n introduction to a professor．

14．You want your essay to be the one that is passed around the admissions office-or not．It's a little bit like the difference between being famous and infamous．
We all know that a truthful，well-written essay that shows how the student has matured is sometimes shared among admissions staffers．（36）ESo how do you make your essay famous instead of infamous？
Here are some basic tips to avoid that infamous essay：
●Avoid the generic（概括的）and get specific．Don't write that you're"fully-developed"or that"many people have impacted"you．（37）G
●Don't repeat information that is elsewhere in your application．（38）D It is important for  the student to use every opportunity to show who they are and impress the admissions office．
●（39）C If you have gone through difficult circumstances，you should share your story．But don't blame others．It's important to show perseverance（毅力）．A better essay will talk about how you have dealt with and overcome the obstacles you came across．
●Don't talk about rankings．Many students love focusing on the numbers when they are writing their"why this college"essay．（40）A Obviously schools are aware of their rankings．They want to know why you want to attend．

A．They believe they are praising the college by mentioning the fact that the college is highly ranked．
B．It also shows the reader that you are thinking about his or her appreciation of your writing．
C．Don't complain．
D．For example，it is not necessary to share your participation level in your essay．
E．But I'm guessing that there are a lot more essays that produce laughter and gasps of"not again"．
F．Don't try to cover everything in an essay．
G．Tell the reader what you've done，how you've been influenced，and by whom．
