Better think twice before choosing a password for e-mail, online bank or shoppin
题型：不详难度：来源：
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.

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 |
Do you know that each child in school catches six to ten colds every year? Though there is no cure for colds, there are some suggestions for you to avoid getting a cold.
First, you can avoid catching a cold by practicing healthy habits. Begin by eating healthy foods. Eat lots of fruits and vegetables and drink milk and juice. Other healthy habits include getting plenty of sleep at night and lots of exercise.
Next, you should try to avoid contact with the viruses that cause colds. If you can, stay away from large crowds. When people cough(咳嗽) and sneeze(打喷嚏), the cold virus goes into the air. Do not share a drinking cup, fork, or spoon with someone else because that could spread the virus. Washing you hands is also a good way not to catch a cold. The cold virus may be on the things like telephones and money. Shaking another person’s hand could even spread the virus. By washing your hands, you can stop the virus from infecting(传染).
Following the suggestion above until doctors find a way to stop the viruses that cause colds.

小题3:When people cough and sneeze, the cold virus the air.

People in different parts of the world use different ways to count on their fingers. In the United States, people think begin counting with their first fingers, which they extend or stick out. They then extend the rest of their fingers and finally the thumb(拇指）to count to five. Then they repeat this with the other hand to get to ten. In China, people count by using different finger positions. In this way, a Chinese person can easily count to ten on only one hand.
Besides ways of finger counting, scientists have found that cultures and languages are also different when it comes to numbers. Some languages have only a few words for numbers, and others have no words for numbers. A group of scientists studied aboriginal(土著的）people in Australia. These people don’t have hand movements to stand for numbers. They don’t even have word for numbers. However, they are still able to understand different ideas about numbers.
In a similar study, researchers from the Massachusetts Institute of Technology discovered that people of the Piraha tribe(部落） in northwestern Brazil don’t have words for numbers such as “one” or “three.”. They are not able to say “five trees” or “ten trees” but can say “some trees,” “more trees,” or “many trees.” Professor Edward Gibson said that mist people believe that everyone knows how to count, “but here is a group that does not count. They could learn, but it’s not useful in their culture, so they’ve never picked it up.”
Although all humans are able to understand quantities(数量）,not all languages have numbers and not all people use counting. Number words in a certain language are a result of people needing numbers in their daily lives. Now we know that people have different ideas about numbers and math, too.

| A．They have only a few words for numbers |
| B．They have hand movements to stand for numbers |
| C．They can only count to five on their fingers |
| D．They can understand different ideas about numbers |
| A．people all over the world know how to count |
| B．People of the tribe have words for number |
| C．Some groups of people are not smart enough to count |
| D．Counting is not useful in the culture of the tribe |
| A．people from different cultures have different ideas about numbers and math |
| B．Chinese people can count more easily on their fingers than Americans |
| C．In some aboriginal culture,people don’t even know how to count |
