A 15-year-old student who invented a flashlight(手电筒) getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research.
Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition.
Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future."
Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors(晶体管).
Ann's prize includes $ 25,000 and a "once in a-lifetime expericnce" from Google for her Hollow Flashlight, which has no moving parts or batteries.
The idea for the invention came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight.
In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5℃ temperature difference between the holder's body and the environment around to produce light."
A video of Ann explaining how she creatcd the flashlight has been watched more than 1.4 million times on the Internet.
Though Ann was successful, she has not made a decision about her career path. Ann hopes that she can find a way to join her love of film and science together.
The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.

Students who get tired of looking at the four walls of a classroom might like to take the nature course being offered by Carvel College again this summer. Groups of about a dozen students each, led by an experienced guide, will go on ten-day camping trips to the mountains to study the plants and animals that grow and live there.
Students carry their own things which include sleeping bags, warm clothing, food and water, and other useful tools. And what do the students do all day? Well, as soon as the sun comes up, they eat breakfast and start climbing up the mountain trail(小路)to the next campground, which is five to ten miles away. The students take notes when the guide points out different plants and animals alongside the trail. The climb is usually over by early afternoon, so the group spends the rest of the day resting or swimming in a mountain lake. Before dinner each night, they all come together and discuss the day’s activities.
At the end of the course, the students write reports using the information they have collected. But they don’t mind at all. What they do mind is leaving the beauty of the wilderness(荒地)and the good friends they’ve made to return to their normal lives in the city.
1.What can the course offer to the students?
A.Better grades in school tests. B.Free vacations in mountains.
C.A different learning experience. D.A chance to study in Carvel College.
2.How far does a student have to walk every day?
A.About five to ten miles. B.About fifty to one hundred miles.
C.About two hundred miles. D.About one hundred and twenty miles.
3.What do the students have to do before dinner?
A.Wash themselves up in a mountain lake. B.Attend classes by the experienced guide.
C.Write about what they see along the trail. D.Review what they learn through discussion.
4.What can we infer from the course?
A.They will change campgrounds every day. B.The students have to learn all by themselves.
C.Pens and books will be useless in the course. D.Carvel College will offer the students everything.

Chinese students in the UK now can get a “taste of home” in their school canteens (餐厅).
The UK has 150 000 Chinese students and more than 89 000 of them are in higher education. Now college kitchens are adapting (修改) menus to provide Chinese food for these students.
In the last week of January, Scot Girvan, a cook at the University of Glasgow, introduced some new dishes more suitable for the Chinese taste.

During the trip, fourteen TUCO members visited Beijing, Guangzhou, Shenzhen and Hong Kong. They learned that Chinese food was different in every place, and offering menu choices from both the north and the south of China was important. At Beijing University’s Nong Yuan canteen, for example, over 350 different dishes are prepared daily and 4700 lunches served.
Inspired (启发) by the Chinese food, Girvan and other TUCO members returned home to carry out the lessons they had learned.
Girvan said he was confident that this would be the case.
