B
China is going green.In order to reduce air pollution and oil shortages, carmakers have announced their plans to develop hybrid vehicles (混合燃料汽车) 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 run on a rechargeable battery and gas.Hybrid cars have special engines, which are smaller than traditional gas engines.The gasoline engine provides 99 percent of the power when the car is going at a steady speed. A specially designed battery motor provides extra power for running up hills or when it needs to speed up.
Step into a Prius, and turn on the engine.The first thing you notice is that it is quieter than a traditional car.At this point, the car’s gas engine is at rest.The electric motor will provide power until the car reaches about 24km/h.If you stay at a low speed, you are effectively driving an electric car, with no gas being used, and no waste gas given off.
The computer decides when to use the gas engine, when to go electric, and when to use a combination of the two.If you go over 24km/h, when you step on the gas pedal (油门), you are telling the computer how fast you want to go.
The electric motor recharges automatically using a set of batteries.And when driving at a high speed, the gas engine not only powers the car but also recharges the batteries.When you use the brake, the electric motor in the wheels will work like a generator (发电机) to produce electricity to recharge the batteries.As a result, the car’s batteries will last for around 200,000 miles.
66.The underlined sentence probably means ________.
A.there will be more and more green land in China
B.China’s new cars are combinations of different green models
C.China is still young and lacking in experience
D.the environment is getting better in China
67. What is the most important feature of hybrid cars?
A. They are powered by both a rechargeable battery and gas.
B. They have smaller engines than traditional gas ones.
C. They only use 99 percent of their power to run up hill.
D. They are much quieter than traditional cars.
68. We can know from the story that ________.
A. the gas engine recharges the batteries as well as powering the car
B. using the brake suggests that the gas engine should work
C. the car’s batteries will last for around 200,000 miles without being recharged
D. the batteries can be recharged at any time you want
69. The author writes the passage mainly to________.
A. announce plans to develop hybrid vehicles for the Chinese market
B. let people know how to save their gas when driving a car
C. teach people how to drive a hybrid car
D. introduce a new kind of “green” car
70.Which of the following statements is TRUE according to the text?
A.The hybrid car is environmentally friendly.
B.The hybrid car is unable to get itself recharged.
C.The hybrid car has been made in mass.

Jerry Springer could easily be considered the king of “rubbish talk”. The contents on his show are as surprising as they can be. For example, the show takes the ever-mon talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark sid

Like Jerry Springer, Oprah Winfrey takes TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.
pared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a “final word”. He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. The sho

A.more interesting | B.more formal |
C.more detailed | D.unusually popular |
A.Family ine planning. | B.Nation hatred. |

One father, for example, says, “When I was young, we were always thinking up things to do, projects and games.We certainly never complained in an angry way to our parents, ‘I have nothing to do”.He compares this with his own children today: “They are simply lazy.If someone doesn’t play with them, they’ll happily sit there watching TV all day.”
There is one word for this father’s disappointment: unfair.It is as if he were disappointed in them for not reading Greek though they have never studied the language.He feels his children’s lack of inventiveness a great pity, as if the ability to play were something born that his children are missing.In fact, the tendency(倾向) to play is built into the human species, but the actual ability to play—to imagine, to invent in a playful way, and the ability to gain satisfaction after successful effort from it—these are skills that have to be learned and developed.
Such disappointment, however, is not only unjust, it is also destructive(毁灭性的).Sensing their parents’ disappointment, children come to believe that they are, indeed, lacking something, and that this makes them less worthy of admiration and respect.Giving children the chance to develop new things to enjoy themselves, to enrich their knowledge and experience and discover the pleasure of doing things on their own is, on the other hand, a way to help children develop a confident(自信)feeling about themselves as able and interesting people.
小题1:Many people think that, instead of watching a lot of TV, their children should_______.
A.think up things to enjoy themselves | B.find chances to talk with parents |
C.enjoy themselves outdoors | D.sit silently studying Greek |
A.they do not lack the ability to play |
B.they have not been given the opportunities to learn and develop their ability |
C.the children are too young to do that |
D.the children are not really lazy, but there’s nothing for them to do |

A.Parents should give children more help on how to be inventive. |
B.Turning off the TV will help us solve a lot of family problems. |
C.It’s not right for parents and children to blame(抱怨) each other. |
D.Today’s children are becoming less able and independent than before. |
A new study that looks at a different set of sensory cues adds to a growing body of evidence that suggests such combination is natural. In a paper, Bryan Gick and Donald Derrick report that people can hear with their skin.
The researchers had volunteers listen to spoken syllables. Meanwhile, they connected the volunteers to a device that would blow a tiny puff (气流) of air onto the skin of their hands or necks. The syllables included “ba” and “pa”, which produce brief puffs from the mouth when spoken, and “da” and “ta,” which do not produce puffs. They found that when listeners heard “da” or “ta” while a puff of air was blown onto their skin, they considered the sounds as “ba” or “pa”.
Dr. Gick said the findings were similar to those from the 1976 study, in which visual cues defeated auditory ones — volunteers listened to one syllable but thought it another because they were watching a video of mouth movements corresponding to the second syllable. In his study,he said,cues from sens

![](http://img.shitiku.com.cn/uploads/allimg/20191212/20191212014803-47037.gif)
Dr. Gick noted that it would normally be rare that someone actually sensed a puff of air produced by another, although people might occasionally sense their own puffs. “What’s so persuasive about this particular effect,” he added. “is that people are picking up on this information that they don’t know they are using.” That supports the idea that combining different sensory cues is natural.
Dr. Gick said the finding also suggested that other sensory cues might be at work in speech perception(知觉) — that, as he put it, “we are these fantastic perception machines that take in all the information available to us and combine it faultlessly.”

A.Humans combine different sensory cues through experience. |
B.Dr. Gick’s new study is more important than the one in 1976. |
C.People sometimes can sense their own puffs when speaking |
D.Only auditory and visual cues are at work in speech perception. |

We learn so much just living from day to day. So why is school important? Of course you can learn some things better at home than at school, like how to do the shopping, and how to help old or disabled people who can’t do everything for themselves. At school, teachers help us to read and write. With their guidance, we begin to see things in different ways.

Scientists first thought the taste of bubbles came from the bubbles bursting on the tongue, but now ate starting to think differently. Charles Zuker, of Columbia University, and his team studied the nervous system of mice to understand how the tongue tastes carbon dioxide, which is the gas that makes up the bubbles.
Animals, including human beings, are able to detect different tastes by using taste buds(味蕾) which pick up tastes in the mouth, and then send them to the brain. In the experiment, different groups of mice were genetically engineered to be missing one of the senses involved in taste. “Genetically engineered” means the researchers were able to turn off the switches for certain senses by changing the genes responsible for taste. The mice in one group could not taste sweet; another, sour; the third, bitter, and the fourth, salt. When the scientists gave carbon dioxide to the mice, the nervous systems of all the mice responded to the gas, except those of the mice that could not taste sour.
This shows that the taste of the bubbles must be sour, and that by turning off the ability of the mice to taste sour, the scientists also turned off their ability to taste carbon dioxide. When they studied the cells that detect sourness, the researchers found a protein attached to the cells that is important to the process of tasting carbon dioxide. When carbon dioxide comes into contact with this protein, the protein knocks off particles called protons. These protons(质子), in turn, travel to the brain, which says ,” Hey! That’s a taste!”
It may seem like a lot of work to get from a can of soda to a taste, but the science of the senses is anything but simple, “ Taste is a challenging system to study,” one researcher says.
小题1: What is the most important function of the bubbles?
A.To look interesting . | B.To make drinks taste good. |
C.To make drinks funny. | D.To produce a lot of fizz. |
A.sourness has nothing to do with the taste of bubbles. |
B.there is a connection between sourness and bubbles. |
C.the taste of bubbles is better if it’s less sour. |
D.most mice cannot taste carbon dioxide. |
A.the taste of bubbles is produced by the bubbles bursting on the tongue. |
B.the nervous systems of mice show how the tongue tastes carbon dioxide. |
C.taste seems simple but is very complex to research. |
D.nerve cells sending signals to the brain is the first step in tasting something. |
A.Nervous Systems Understand How the Tongue Tastes. |
B.The Process of Taste |
C.The taste![]() |
D.Different Animals Detect Different Tastes. |
