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.

A password is like a key to your home. If someone steals it, he’ll get chances to steal something else. We use passwords everywhere in our life. We are so used to passwords that we don’t pay any attention to them until we lose or forget one.
A study of 28,000 passwords recently stolen from a popular website showed that people often do the easy thing. It found that 16 percent took a first name as a password. Another 14 percent used the easiest keyboard combinations such as “12345678” or QWERTY. Five percent of the stolen passwords were names of television shows or stars popular with young people. Three percent of the passwords expressed feelings like “I don’t care,” “Whatever,” “I love you,” or their opposite, “I hate you.”
Robert Graham, who did the study, advises people to choose a password that is longer than eight characters with one capital letter(大写字母) and one symbol.
Of course, safe passwords don’t mean those hard to remember. Forgetting your password is sometimes a big headache for you. Maybe, the perfect password is easy for you and hard for others.
小题1: The underlined word “password” in Paragraph 1 means __________.
| A．标志 | B．护照 | C．密码 | D．口诀 |

Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. “This is long enough for other planets to have intelligent life,” say Shostak and Barnett. The second reason is size—the universe is huge. “Tools like the Hubble Telescope(哈勃望远镜) have shown that there are at least 100 billion galaxies,” says Shostak. “And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth.”
In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes(高倍望远镜) allow scientists to discover smaller planets—the size of Mars or Earth—in other solar systems. These planets might have intelligent life.
Have beings from space already visited Earth? “Probably not,” says Shostak. “It’s a long way away. However, intelligent beings may contact us in other way, such as radio signals(信号). In fact, they may be trying to communicate with us now, but we don’t have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other.”
小题1:Seth Shostak and Alexandra Barnett are _____.
| A．astronomers | B．farmers | C．singers | D．drivers |
| A．The Age and Size of Earth |
| B．Our Galaxy: The Milky Way |
| C．Why Intelligent Life Might Exist |
| D．Earth: The Only Planet with Intelligent Life |
| A．There were not any smaller planets. |
| B．There were not any powerful telescopes. |
| C．The astronomers were not interested in them. |
| D．The Milky Way didn’t exist at that time, |
| A．They’re afraid of us. |
| B．It’s a long way away. |
| C．They don’t want to see us. |
| D．They don’t know how to use radio signals. |
| A．Messages | B．Tools | C．Intelligent beings | D．Radio signals |
