There 40 students were selected from almost 2,000 contestants nationwide. They had to present original research to be judged by professional scientists. The students showed their research projects on large posters. The winners were announced on March 15th, 2011.

Wendy Hawkins is executive director of the Intel Foundation, Who says the 40 finalists represented excellence across many areas of science.

Selena Li is from Fair Oaks, California, She wanted to find a more effective treatment for liver cancer. She began her research four years ago. A scientist at the University of California, Davis, taught her how to design and do experimental work in the laboratory. Ms. Li placed 5th in the Intel Science Talent Search and was awarded 30,000 dollars.

Scott Boisvert lives near Phoenix, Arizona. He began using a laboratory at the university of Arizona at the age of 14. Over four years, he completed a project studying a fungus(真菌)linked to the decrease in amphibians(两栖类动物)around the world. He was trying to find out if different chemicals and substances in the water could kill of fungus. He collected and tested water samples across Arizona. He says,“My results were able to identify a list of chemicals that were significant in the growth and in the movement of the fungus.”He placed 10th in the Intel competition and was awarded 20,000 dollars.

Evan O’Dorney of Danville, California, won the top award of 100,000 dollars in this year’s Intel Science Talent Search. For his mathematical project, He compared two ways to estimate the square root of an integer, a number with no fractional parts.

Until today, the Don Milani di Rivoli elementary school in central Turin was like any other. Children turned up, got out their books and pens and began the process of learning. But now, in what's being described as a unique experiment, 60 fifth-grade pupils and a number of third-graders, will start using computers only.

The mini-laptops, which run Windows software, all have a full curriculum programmed into them. The pupils will use the computers to do all their reading and writing. Security systems within the laptops mean the children's access to the Internet is strictly controlled. The machines weigh less than a kilogram, can be dropped from a height of 1.5 metres and are waterproof.

Instead of spending 700 dollars a year on books, the laptops, built by the Italian company Olidata, cost less than 400 dollars. One of the teachers involved in the scheme says that, for the first time, schools will be able to verify in a scientific way how a computer alone can improve the learning process. The experiment, which has the backing of parents, is due to last a year.

In other countries, such a programme is also being carried out. Venezuela is ordering one million low cost laptops for its school children. The machines will be based on the Intel Classmate laptop that has been designed for school children. Many see the deal as a blow for the One Laptop Per Child organization that has also been introducing its child- friendly machine to developing nations.

Which of the following is TRUE about the mini-laptop?

A. It is heavy for pupils to carry. B. It can't be damaged by water.

C. It is one and a half meters high. D. It is easily broken or damaged.

The pupils use the laptop to ____ in class.

A. learn their lessons as an aid

B. have a course named computer studies

C. surf the Internet mainly to find information

D. do what they used to do with books and pens

How much money can a pupil save by using the mini-laptop to replace all the books in a year?

A. Less than 400 dollars. B. More than 400 dollars.

C. More than 300 dollars. D. Less than 300 dollars.

Which of the following about the experiment is TRUE?

A. It has been carried out for over one year.

B. It has already turned out to be a success.

C. The pupils' parents are against it in fact.

D. The pupils' parents are supportive to it.

Children at a school in Italy have today begun an experiment to replace all their books with personal computers. The pupils involved will each be given a special laptop that contains their entire courses.

【小题4】The Wendy Hawkins’s attitude to these 40 finalists is ______.

Erica David lives in Pinedale,Wyoming，USA，where winter can bring temperatures of below 35 degrees Fahrenheit，howling winds，and a lot of snow．So it was just natural that she chose to study snow for her school science fair in the sixth grade．

Now a junior in high school，Erica is in her sixth year of snow experiments，and is well on her way to becoming a snow expert．She started with a basic question：Could snow fences be built to work better?

Snow fences are used to keep snowdrifts（雪堆）from covering areas like roads of train tracks，or to help build up snow where it can help with water shortages in spring when it melts（融化）．“Also，I wanted to protect my animals better from blowing snow，”says Erica，who raises goats，sheep，and pigs．

Before she could test fence designs，Erica had to figure out what would act like real snow in her experiments. “I tested flour, sugar, and salt before I settled on dishwasher powder , ”she explains.

Science fairs offer students the chance to test theories, present findings to judges, and meet other researchers. Erica’s many achievements include competing at the Discovery Channel Young Scientist Challenge for middle school students and the Intel International Science and Engineering Fair, where students from around the world present their science research.

But perhaps the best reward is that her research is already being put to good use. She has come up with an improved snow fence design, and this year she’s helping think out how to provide water supply to native plants, which have been killed off by drilling at nearby natural gasfields.

“Science fairs are an amazing experience,”says Erica. “Just pick your true feeling and go for it. ”

72. What does the passage suggest to us?

A. Science fairs are held for high school students in America.

B. Erica is the youngest show expert well known in America.

C. The environment brought much convenience for Erica to study snow.

D. The hope to contribute to her hometown made Erica experiment on snow.

73. In Erica’s hometown, snow fences may play a part in ________.

a. reducing the harm blowing snow does to animals

b. supplying water resource to the nearby gas fields

c. making up for the lack of water resource.

d. keeping the traffic smooth

A. a,b,c B. a,b,d C. b,c,d D. a,c,d

74. Science fairs are attractive to students because they ________.

A. can have their research put into practical use

B. can have their scientific ideas tested out

C. are allowed to help protect the local wildlife

D. can learn about the most advanced technology

75. Which of the following material can best replace snowing in Erica’s experiment?

A. Flour. B. Sugar. C. Salt. D. Dishwasher powder.

1. Which of the following is TRUE about the mini-laptop?
