ALBANY，New York—Students who rely on working at night to improve their

grades might want to sleep on that strategy: A new survey in the US says those who never study all night have slightly higher grades than those who do.

A survey of 120 students at St.Lawrence University found that students who had never pulled an all??nighter on average had higher grades than those who had. The survey found those who did not study through the night had a grade point average of 3.2 compared to 2.95 for those who did.

The study, by assistant professor of psychology Pamela Thacher, is to be included in the January issue of Behavioral Sleep Medicine.

“It's not a big difference，but it's pretty striking, ” Thacher said, “I am primarily a sleep researcher and I know nobody thinks clearly at 4∶00 in the morning. You think you can do，but you can't.”

Many college students, of course, have inadequate or irregular sleep, for reasons ranging from excessive caffeine to poor time management.

“A lot of students were under the impression that all??nighters were a very useful tool for accomplishing work, and that caffeine intake was very useful in meeting deadlines and stuff like that, ”said Mr Chatani, who had a 3.4 grade point average last term.

Dr Howard Weiss, a physician at St.Peter's Sleep Center in Albany, said the study results made sense.

“Certainly that data is out there showing that short sleep duration absolutely interferes with concentration and performance on objective testing, ”he said.

“Some night owls do get good grades, of course，which may be explained by circadian (昼夜节律的，生理节奏的) rhythms, ”Weiss said, “Some people have different 24??hour body clocks from others, and may do better depending on classes and testing time.”

The purpose of the passage is to tell us 　　　　

  A. the bad effects of pulling an all??nighter

  B. pulling an all??nighter leads to sleep problems

  C. Thacher's doubt about all??nighters

  A. one can think more clearly

  B. one has his/her best memory

  C. one can't learn efficiently

  D. one's brain falls into a period of deep sleep

What can we know from Dr Howard Weiss' words？

  B. He believes in Thacher's study.

  C. Thacher's study makes no sense.

  D. Thacher should take exceptions into consideration.

In America, when people say “man’s best friend”, they don’t mean another person. Instead, they are talking about a lovely animal：A dog! These words show the friendship between people and animals. Dogs and other pets can give happiness to people’s lives. Some people think of their pets as their children. A few even leave all their money to their pets when they die!

   Animals can help people, too. Dogs can be taught to become the “eyes” for a blind person or “ears” for a deaf people. Scientists have found that pets help people live longer! They make people happier, too. Because of that, animals are brought into hospitals for “visit”.

   Americans hold “Be-Kind-to-Animals Week” in the first week of May.

   Pets shows are held during the week. Even if you don’t live in America, you, too, can do this. How? First, think about how animals make your life richer. If you have a pet, take more time this week to play with it. Remember to give it delicious food. Also, be sure to keep your pet from those unwanted babies.

   If you don’t have a pet, be kind to animals around you. For example, if you see a street dog, don’t kick it or throw things at it. Instead, just leave it alone, or better yet, make friends with it. If others around you do bad things to an animal, try to stop them. As people, we must protect animals who can’t speak for themselves.

“A few even leave all their money to their pets when they die!” means that__________

Recently the World Health Organization announced that the disease of

smallpox（天花）had almost been wiped out in most parts of the world, thanks to widespread vaccination（种牛痘）. Most people are vaccinated at least once in their lives and if they wish to travel from one country to another they must be able to prove that they have had a recent vaccination. In this way the disease has been prevented from spreading and today one seldom hears of it at all.

This is mainly because of the great discovery made by a village doctor, Edward

Jenner, in about 1798 when he published his report of his new experiment called vaccination (from the word ‘vacca’ meaning a cow). Jenner discovered that people who worked with cattle often suffered from a harmless disease which they caught from the cattle, but these people never seemed to get smallpox. So he experimented by putting the disease into a small opening on the arms of healthy people, and though their arms became painful for a day or two, they soon recovered and none of these people ever got smallpox.

So the news of the wonderful discovery spread to other countries and people

rushed to their doctors to be vaccinated. In many countries the simple way to deal with the arm was done on thousands of people, and the terrible smallpox began to disappear.

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．

D．The hybrid car can decide what power to use
