The term “multitasking” originally referred to a computer's ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic exercises (大脑训练) involve engaging the brain in two or more challenging activities at a time. Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that too much multitasking can lead to increased stress, anxiety and memory loss.
In order to multitask, the brain uses an area known as the prefrontal cortex (前额叶脑皮层). Brain scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you've ever dialed (拨电话) a phone number and suddenly forgotten who you called when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to another thought or task, and then took that “moment” to come back. Research has also shown that for many volunteers, job efficiency (效率) declines while multitasking, as compared to when they perform only one task at a time.
Multitasking is easiest when at least one of the tasks is habitual, or requires little thought. Most people don' t find it difficult to eat and read the newspaper at the same time. However, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.
We often don't remember things as well when we're trying to manage several details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget people's names—even sometimes right after they have introduced themselves. Multitasking can also affect our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. It can also cause that person to miss or overlook key information being passed on to them.
1. Why are some mental aerobic exercises designed to engage people in multitasking?
A. To make them more productive.
B. To reduce their stress and anxiety.
C. To develop their communication Skills.
D. To help them perform daily tasks more easily.
2. According to Paragraph 2, why may a person suddenly forget who he has called?
A. He may have his prefrontal cortex temporarily damaged.
B. He is probably interrupted by another task.
C. He is probably not very familiar with the person he has called.
D. He may need a rest between dialing and speaking.
3. People tend to make mistakes when .
A. they perform several challenging tasks at a time
B. new messages are processed one after another
C. their relationships with others are affected
D. the tasks require little thought
4. What is the main idea of the passage?

B. Multitasking often leads to efficiency decline.
C. Multitasking exercises need to be improved.
D. Multitasking enables people to remember things better.

While Nick was on the bus, reading his newspaper, the man sitting next to him suddenly pushed a large envelope into his hands. “Here, take this!” the man said, stood up and got off the bus before Nick could say a word.
Nick sat there, holding the envelope. It felt heavy. There were papers inside, or money perhaps. “I’d better hand it over to the police,” he thought. There was a police station close to his office. But, as he got off the bus, a man came to him. He seemed to be waiting for something. “He wants the envelope,” Nick thought. Nick began to walk quickly, and the man hurried after him. Nick started to run, and the man began to run, too. But then, just before he got to the police station, Nick managed to lose the man in the crowds. When he entered the police station, the man was no longer in sight.
Inside the police station, Nick handed over the envelope to a policeman in charge. The man opened it. The envelope was full of money, false money. “Clearly the man made a mistake,” the policeman said. “He thought you were one of the gang (团伙)!”
Nick felt like a hero. He could already see his name in all the papers. He could imagine an interview on television.
“However,” the policeman went on, “I’m afraid I must ask you to keep quiet about all this. We’re trying to catch some very clever thieves, and we don’t want them to know that we have some of the money. So you mustn’t say a word to anyone – not even your boss!”
1.The man who suddenly gave Nick an envelope was most probably________.
A．Nick’s friend B．a thief C．the bus driver D．a postman
2.Nick decided to give the envelope over to the police probably because_________.
A．the whole thing was strange
B．another man was waiting for it
C．he didn’t want the money inside it
D．the police station was near his office
3.As Nick got off the bus, a man came to him because_________.
A．he wanted to catch Nick
B．he thought Nick was a policeman
C．he wanted to give Nick some money
D．he thought Nick was one of their gang
