About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred if affected in this matter. Perhaps, after all, it is safer to be driven by a woman.
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can’t tell the differences between blue and green. In rare cases an unlucky man sees everything in shades of green--- a strange world in deed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions very small things called “cones”. These help us see in a bright day and tell the differences between colors. There are also millions of “rods”, but these are used for seeing when it is nearly dark. They show us shapes(形狀) but not color. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects but a blue lamp will. In similar way human being also have favorite colors. Yet we are lucky. With the aid of cones in our eyes we can see many beautiful colors by day and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
【小題1】The passage is mainly about ______.
A.color and its surprising effects on drivers |
B.women being luckier than man in that fewer of them are color blind |
C.danger caused by color blindness |

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.
【小題1】What can we learn from Paragraph l?
A. Driverless vehicles are now legal in the whole USA.
B. Volvo will be the first to sell driverless cars.
C. Driverless cars are pointing us' a faraway future.
D. Google's self-driving cars have covered a long distance.
【小題2】We learn that Governor of California Jerry Brown_________.
A.helped design self-driving cars. |
B.supports self-driving cars on roads. |
C.considers self-driving cars science fiction. |
D.improved the self-driving car systems. |
A.They can help people drive more safely. |

Yawning sends out certain messages -either “Oh ,this movie is so boring” or “I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is overheated?
A new study, led by a research team at Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com.
The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.
When people yawn, their jaw is also stretched ,which increases blood flow and may also help cool the brain
The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.
However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.
According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.
【小題1】The purpose of the experiment is ______.
A. to prove people yawn in winter and in summer equally |
B. to indicate brain can regulate temperature naturally |
C. to find the frequency of people’s yawning |
D. to show the real reason why people yawn |
A. longer outdoor summertime results in more yawns |
B. yawning frequency changes with outdoor time |
C. yawning frequency increases with outdoor time |
D. longer outdoor wintertime leads to fewer yawns |
A. Yawning Is A Sign of Brain Disease |
B. Yawning Carries Some Information |
C. Yawning Benefits Your Body |
D. Yawning Cools Your Brain |

China is going green. In order to reduce air pollution and oil shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽車(chē)) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (勻速行駛). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard (車(chē)載的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油門(mén)), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.
【小題1】The author writes this passage mainly to________.
A.teach people how to drive a hybrid car |
B.introduce a new kind of “green” car |
C.show how to save their gasoline when driving a car |
D.a(chǎn)nnounce plans to develop hybrid vehicles for China |
A.The hybrid cars reduce air pollution and oil shortages. |
B.The car's gasoline engine doesn't work until it reaches about 24 km/h. |
C.This kind of car is completely controlled by an onboard computer. |
D.A specially designed battery motor provides extra power when needed. |
A.They are powered by both a rechargeable battery and gasoline. |
B.They are much quieter than traditional cars. |
C.They only use 99 percent of their power to run up hills. |
D.They have smaller engines than traditional gasoline ones. |
A.The batteries can be recharged at any time you want. |
B.Using the brake suggests that the gasoline engine should work. |
C.The batteries will last for 200, 000 miles without being recharged. |
D.The gasoline engine charges the batteries as well as powers the car. |

Play allows children to use their creativity while developing their imagination and physical, cognitive (認(rèn)知的), and emotional strength. Play is important to healthy brain development. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles. Undirected play allows children to learn how to work in groups, to share, to negotiate, and to resolve conflicts.
Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce (順從) to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem.
Children’s development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children’s vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children’s world learn to communicate more effectively with their children and are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children.
Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional development of children as well as their cognitive development. It has been shown to help children adjust to the school setting and even to strengthen children’s learning willingness. Social-emotional learning is best integrated (融合) with academic learning; it is concerning if some of the forces that enhance children’s ability to learn are improved at the expense of others. Play and unscheduled time that allow for peer interactions are important components of social-emotional learning.
【小題1】Compared with undirected play, play which is controlled by adults ________.
A.doesn’t benefit the children at all |
B.doesn’t help develop leadership and group skills |
C.makes children become more active |
D.helps increase physical activity levels |
A.play offers parents a good chance to establish good relationships with children |
B.children’s development is greatly influenced by relationships with parents |
C.play helps children better express their views |
D.play offers parents a unique opportunity to see the world from a different perspective |
A.play can’t help children become adapted to the school setting |
B.play makes social-emotional learning and academic learning separated |
C.play is beneficial to social-emotional learning as well as academic learning |
D.it is necessary to strengthen children’s academic development at the expense of others |
A.Undirected play can help children develop team spirit. |
B.Play can improve children’s willingness to learn. |
C.Play helps adults gain a better understanding of the children’s thoughts. |
D.Adults shouldn’t be involved in children’s play. |

Everyone has got two personalities-the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control your behavior, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their positions. The important position is the one that you go to sleep in.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to displease people. So you never express your real feelings. You’re quite shy and you aren’t quite sure of yourself.
If you sleep on your stomach, you are a rather secretive person. You worry a lot and you’re always easily upset. You always stick to your own opinions or judgment, but you don’t raise your hopes too much. You usually live for today not tomorrow. This means that you enjoy having a good time.
If you sleep curled up, you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.
If you sleep on your side, you have usually got a well—balanced personality. You know your strengths and weakness. You’re usually careful. You believe in yourself. You sometimes feel anxious, but you don’t often get sad. You always insist on what you think even if it makes people rather angry.

For some people, music is no fun at all. About four percent of the population is what scientists call “amusic.” People who are amusic are born without the ability to recognize or reproduce musical notes (音調(diào)). Amusic people often cannot tell the difference between two songs. Amusics can only hear the difference between two notes if they are very far apart on the musical scale.
As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their inability to enjoy music set them apart from others. It can be difficult for other people to identify with their condition. In fact, most people cannot begin to grasp what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics intentionally stay away from places where there is music. However, this can result in withdrawal and social isolation. “I used to hate parties,” says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition.
Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complex, and it doesn’t involve defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can’t see certain colors.
Many amusics are happy when their condition is finally diagnosed. For years, Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. “When people invite me to a concert, I just say, ‘No thanks, I’m amusic,’” says Margaret. “I just wish I had learned to say that when I was seventeen and not seventy.”
【小題1】Which of the following is true of amusics?
A.Listening to music is far from enjoyable for them. |
B.They love places where they are likely to hear music. |
C.They can easily tell two different songs apart. |
D.Their situation is well understood by musicians. |
A.dislikes listening to speeches | B.can hear anything nonmusical |
C.has a hearing problem | D.lacks a complex hearing system |
A.her problem with music had been diagnosed earlier |
B.she were seventeen years old rather than seventy |
C.her problem could be easily explained |
D.she were able to meet other amusics |
A.Amusics’ strange behaviours. |
B.Some people’s inability to enjoy music. |
C.Musical talent and brain structure. |
D.Identification and treatment of amusics. |

About 35 percent of British adults sleep with teddy bears. Many more share a bed with a partner or spouse. Others still co - sleep, alongside children in a family bed.
But lying with your iPad? A recent survey by marketing agency Rosette found that 68 percent of tablet owners use the device in the bedroom, more than in any other location. The living room took a close second place, at 63 percent, reports AdAge. com, and only 45 percent of respondents said they use their tablets on the go.
But bringing devices into the bedroom is a bad idea, if quality rest is your goal. One of the most important factors of sleepiness is darkness, which signals to the brain that it’s time to start speeding up production of the sleep - inducing hormone melatonin. But as the New York Times points out, in our modern world, we are exposed to light long after the sun sets. While any type of light can disturb your sleep, the blue wavelength light given off by cell phones, laptops, tablets and other gadgets is particularly troublesome. Research shows that this blue light causes alertness so decisively that it can actually be used to fight tiredness.
According to the National Sleep Foundation, 95 percent of Americans use some device, whether it’s a TV, laptop, cell phone or other products, within an hour of killing time. “Artificial light exposure between dusk and the time we go to bed at night push our sleeping sense to a later hour - making it more difficult to fall asleep,” said Charles Czeisler, Ph. D. , M. D. , chief of the division of sleep medicine at Brigham and Women’s Hospital in Boston.
Instead, experts recommend turning off all devices an hour before bedtime and finding another method for relaxation, like reading a book, taking a warm bath or performing a series of calming yoga poses. It’s also a good idea to exercise and lay off the caffeine several hours before bedtime.
【小題1】 According to a recent survey, most tablet owners use their iPad ________.
A.in the living room | B.in the bedroom |
C.in the office | D.on the move |
A.The light from cell phones is harmful |
B.Modern people have trouble falling asleep |
C.Darkness can create a good sleeping environment |
D.Blue light can prevent sleepiness decreasing |
A.dream of it | B.stay awake | C.feel sleepy | D.become tired |
