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.

But we think and learn that it was made about during the Han dynasty (BC206-AD220). The Silk Road covered the distance of about 7,000 kilometers. The Silk Road wasn’t actually one road. It was actually many roads that ran through different countries. The roads linked(连接) China to Rome. They ran through high mountains and the harsh(严酷的) deserts.
How many different towns, cities or countries do you think there were along the Silk Road? Nobody knows exactly how many towns, cities or countries there were. But some of the countries were China, Turkey, Iraq, Iran, Afghanistan, Pakistan and Syria. There were three main routes, and they were very dangerous. The northern route was from China to the Black Sea. The central route was from China to Persia, the Mediterranean Sea(地中海) and Rome. The last route, the southern route, was from China to Iran and India. It was very necessary for merchants(商人) to trade their goods from China to the west.What does the Silk Road mean in Chinese?

April will bring a new product - the Apple Watch - into the market. Last week, the watch was firstly introduced by Tun Cook, Apple's CEO. The price of the watch will differ from $349 to $1,099, depending on its size, strap and whether it is a sports or regular style.
Apple engineers and designers have put in a lot of thought and hard work into creating this "small screen" on your wrist(手腕). The "sensor" on the screen not only detects your finger, but knows the difference between when you are tapping, and when you are pressing harder.
The watch also has "hal)tic feedback(触觉反馈)". You can send personal messages to your friend - such as drawing a star or a special sign with your fingers, or tapping the watch, say 3 times, and your friend will receive those taps on their wrist. Besides telling the time, the watch will use bluetooth' to connect with your iPhone and show calls or text messages that come in.
According to Tim Cook, the watch may open up a whole new area of applications that we had never thought of. Some car factories like BMW have developed an app that allows its car owners to open their cars with the watch. A Hotels' app may allow you to open the door to your hotel room without worrying about losing the smart-card. And finally, even airlines are jumping in - passengers may be able to simply wave their wrist to check into their flight.
The biggest use of the watch, however, is as your personal fitness coach. The watch can measure your pulse (heartbeat) using a sensor at the bottom of the watch. It also has the same "accelerometer" as your iPhone, so it knows when you are moving, and also how much you are walking or running, It will remind you if you have been sitting for too long without much activity.
