Roland was a worker in Virginia. He and Sheila had three kids—two boys and baby Jessica. The baby had been in and out of the hospital for the last year because of some serious problems. She was very weak and sick. The doctors were not sure if she would live another year.
Taking care of Jessica was expensive. The family needed money very much. Things were bad. Then Roland saw an ad in the newspaper: “Security guards(安全警卫) wanted. $100, 000 a year. ” He called the number. The line was busy, but he kept calling and finally got through. They said they would give him two weeks of training in Texas. Then they would fly him to Iraq.
Roland told Sheila he had to take this job. He knew it was dangerous; he might get injured or killed, but the money was too good. He wanted the baby to get the care she needed. But Sheila was worried and asked, “What if you get killed What are we going to do without you ”
“You can’t think like that, ” he said. “Think about how well off we’ll be in two or three years after I bring back all that money. This is the best thing I could do for this family. ”
Sheila hugged him and cried, “I don’t want you to go. ”

As Internet users become more dependent on the Internet to store information, do people remember less If you know your computer will store information, why do you store it in your own personal memory Experts are wondering if the Internet is changing what we remember. In a recent study, Professor Betsy Sparrow made some experiments(实验). She and her research team wanted to know how the Internet is changing memory.
In the first experiment, they asked two groups of people to put 40 unimportant facts into a computer. The first group of people understood that the computer would store the information The second group understood that the computer would not store it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.
In the second experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in an exact computer folder(文件夹). Surprisingly, people later remember the folder location better than the facts. When people use the Internet, they do not remember the information. However, they remember how to find it. This is called “transactive memory(交互记忆)”
According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize a lot of information so that they are able to get it at a later date. This doesn’t mean we are becoming either more or less clever but there is no doubt that the way we use memory is changing.
6. Why does the writer begin the text with two questions
A. To explain some thoughts. B. To introduce the main topic.
B. To show an opinion. D. To draw the readers' attention.
7.What can we learn from the first experiment
Sparrow put the information into the computer
B. Both groups remembered the information well.
C. Group 1 remembered the information faster
D. Group 2 remembered the information better.
8.What do we know about transactive memory from the second experiment
A. People organize the information like a computer.
B. People remember how to find the information.
C. People remember how to make a folder.
D. People keep the information in mind.
9. What does the underlined word “location” probably mean
A. Space. B. Square. C. Place. D. Memory.
10. What’s the text written for
A. Describing the organizing of computers on people’s memory.
B. Introducing the influence of computers on people’s memory.
C. Telling the harm of computers to people’s memory
D. Showing the development of stronger memories.
