2．Did you know that there are actually people who have paid for a flight to the moon？In the future，there will be a lot more opportunities to travel to faraway places than now…perhaps even as far as the moon．As people adventure further and further away and as planes，trains，cars，and rocket ships become faster，is it safer to have these vehicles controlled by humans or by computers？
While many flights by plane are controlled automatically by machines，most people today wouldn't let their car drive itself．That's because currently the autopilot function on your car can only keep it on the same course you are travelling on．It won't turn the car right or left．It won't stop if an animal jumps in the way．However，cars today can sense when something is too close and warn the driver with flashing lights and alarms．Many cars also have GPS（global positioning systems） that tell drivers which road to take and when to turn．These systems，unlike human drivers，never get lost．In the future，it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at．
In addition to computers being‘smarter'than people regarding the best way to go or knowing how close another vehicle is，computers don't get sick，tired，or angry．This means they won't make the same mistakes that people make when they are not having a good day．While responding with emotion is a good thing when choosing the best way to deal with a friend's personal problem，it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle．
So what are the disadvantages of autopilot systems？Maybe one disadvantage is that a small computer problem could cause a serious accident．It could also be argued that in unexpected situations，computers might not be able to respond appropriately； some decisions require human emotions．Another problem might be that if everything were controlled by computers or robots，people wouldn't have any jobs．

67．What is the best title for the passage？B
A．The Development of Autopilot
B．Technology of Future Travel
C．A New Driving System
D．Computerized Cars
68．Which of the following is the disadvantage of an autopilot system？C
A．It won't make the same mistakes as people do．
B．It can point out the best route for the driver．
C．It might not respond properly to unexpected situations．
D．It does not have human emotions to influence its function．
69．If some falling rocks roll down toward your car，the autopilot on your car willA．
A．inform you of the danger
B．turn the car right or left
C．do nothing about it
D．stop the car
70．What's the author's attitude towards the autopilot？B
A．Approving． B．Objective． C．Negative． D．Doubtful．

10．A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it．Some children reach eagerly for the treat they see．Some last a few minutes before they give in．But others are determined to wait until the last moment．
By the time the children reach high school，something remarkable has happened．A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular，adventurous，confident and dependable．The children who gave in to temptation（誘惑） early were more likely to be lonely，easily frustrated and inflexible（頑固的）．
Actually，the ability to delay reward is a sign of emotional intelligence which doesn't show up on an IQ test．
The hardware of the brain and the software of the mind have long been scientists'concerns．But brain theory can't explain what we wonder about most，like the question why some people remain upbeat in the face of troubles that would sink a less resistant soul．
Here comes the theory of Daniel Goleman，writer of Emotional Intelligence：when it comes to predicting people's success，brain ability measured by IQ may actually matter less than the qualities of mind once thought of as"character"．
EQ is not the opposite of IQ．What researchers have been trying to understand is how they work together； how one's ability to handle stress，for instance，affects the ability to concentrate and put intelligence to use．Among the ingredients （要素） for success，researchers now generally agree that IQ counts for about 20%； the rest depends on everything from social class to luck．
While many researchers in this relatively new field are glad to see emotional issues finally taken seriously，some few fear EQ causes misuse．

66．The experiment with the four-year-olds makes it clear thatC．
A．the age of 4 is a proper time for scientific experiment
B．emotional intelligence won't show up until adolescence
C．the ability of self-control plays a role in personal success
D．candy can be used to measure a person's emotional intelligence
67．Which of the following is TRUE of EQ and IQ according to the text？D
A．There is no link between EQ and IQ．
B．The higher a person's IQ is，the higher his or her EQ is．
C．Some people can be blessed with lots of both，but some with little of either．
D．Scientists are trying to discover the way in which EQ and IQ work together．
68．The underlined word"upbeat"in Paragraph 4 probably means"D"．
A．kind        
B．floating        
C．excited         
D．optimistic
69．Why does the author mention the experiment at the beginning of the text？C
A．To amuse both the children and readers．
B．To prove the scientist's wisdom．
C．To introduce the topic of the text．
D．To show us how to do an IQ test．
70．What is most likely to be written in the paragraph that follows？B
A．Information about famous people with high EQ．
B．Examples showing the opposite voice about EQ．
C．Some reasons why EQ is relatively new field．
D．Strong demands for basic emotional education．

17．Some colors people see late at night could cause signs of clinical depression．That was the finding of a study that builds on earlier study findings．They show that individuals who live or work in low levels of light overnight can develop clinical depression．Doctors use the word"clinical depression"to describe severe form of depression．Signs may include loss of interest or pleasure in most activities，low energy levels and thoughts of death or suicide．
In the new study，American investigators designed an experiment that exposed hamsters（倉鼠）to different colors．The researchers chose hamsters because they are nocturnal，which means they sleep during the day and are active at night．
The animals were separated into four groups．One group of hamsters was kept in the dark during their night-time period．Another group was placed in front of a blue light，a third group slept in front of a white light，while a fourth was put in front of a red light．
After four weeks，the researchers noted how much sugary water the hamsters drank．They found that the most depressed animals drank the least amount of water．
Randy Nelson heads the Department of Neuroscience at Ohio State University．He says animals that slept in blue and white light appeared to be the most depressed．"What we saw is that these animals didn't show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim（微弱）red light，they did not．"
Randy Nelson notes that photosensitive（感光）cells in the eyes have little to do with eyesight．He says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle．
He says there's a lot of blue in white light．This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness．

25．Researchers use hamsters in the experiment becauseD．
A．they are similar to humans in dealing with colors
B．they are easy to observe and study
C．they are sensitive to colors like human beings
D．they are active at night and sleep during the day
26．What sign shows that the hamsters are being depressed？A
A．They drink less sugary water．
B．They don't sleep well．
C．Their eyesight becomes worse．
D．Their energy level becomes low．
27．Ctends to cause hamsters to be depressed．
A．Dim light 
B．Red light
C．Blue light 
D．Darkness
28．What can help people who work late at night to avoid being depressed？B
A．Not being exposed to dim red light when using computers．
B．Equipping their computer screens to put it more in the reddish light．
C．Living or working in low levels of light overnight．
D．Going to see doctors of clinical depression regularly for help．

7．Running on Empty
For almost a century，scientists have assumed，tiredness-or exhaustion-in athletes originates in the muscles（肌肉）．Precise explanations have varied，but all have been based on the"Limitations Theory"．In other words，muscles tire because they hit a physical limit； they either run out of fuel or oxygen or they drown in harmful by-products （副產(chǎn)品）．
In the past few years，however，Timothy Noakes from the University of Cape Town． South Africa，has examined this standard theory．Tiredness，he argues，is caused not by signals springing from overtaxed muscles，but is an emotional response which begins in the brain．The fundamental nature of his new theory is that the brain paces the muscles to keep them well back from the edge of exhaustion．When the brain decides it's time to quit，it creates unbearable muscle tiredness．This"Central Governor"theory remains controversial，but it does-explain many puzzling aspects of athletic performance．
A recent discovery that Noakes calls the"lactic acid paradox"made him start researching this area seriously．Lactic acid is a by-product of exercise，and the increase of it is often mentioned as a cause of tiredness．But when research subjects exercise in certain conditions created artificially，they become tired even though lactic acid levels remain low．
Nor has the oxygen content of their blood fallen too low for them to keep going．Obviously，something else was making them tire before they hit either of these physiological limits． Noakes conducted an experiment with seven cyclists．It has long been known that during exercise，the body never uses 100% of the available muscle fibres （纖維）．The amount used varies； but in some tasks such as this cycling test the body calls on about 30%．His team found that as tiredness set in，the electrical activity in cyclist's legs declined-even when they were making a great effort to cycle as fast as they could．
To Noakes，this was strong evidence that the old theory was wrong．"The cyclists may have felt completely exhausted，"he says，"but their bodies actually had considerable reserves that they could theoretically tap by using a greater amount of the resting fibres．"
This，he believes； is the proof that the brain is regulating the pace of the workout to hold the well back from the point of extreme tiredness．
67，Which of the following is supported by the"Limitations Theory"？B
A．Tiredness is caused by signals from brain．
B．Athletes feel tired when they use up all their energy．
C．The body uses 100% of the muscle fibres in exercise．
D．Athletes become tired though lactic acid levels remain low．
68．Noakes has found out that．C
A．muscle fibres control athletes'movements
B．lactic acid levels remain high in cycling test
C．mental processes control the symptoms of tiredness
D．different exercises use different amount of muscle fibres
69．It is likely that both theories accept that．A
A．lactic acid is produced in muscles during exercise
B．the oxygen content in blood may rise after sports
C．tiredness is a harmful by-product of exercise
D．the energy in human bodies can be
70．What is Paragraph 3mainly about？C
A．The description of a new test．
B．The explanation of the theory．
C．The puzzling evidence of a study．
D．The whole process of the research．
