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 (大腦訓練) 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 (前額葉腦皮層). Brian 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 (撥電話) a phone number and suddenly forgotten who you dialed when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to anther 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.

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.    

According to Paragraph 2, why may a person suddenly forget who has called?

A. He may leave 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.

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

What is the main idea of the passage?

A. Multitasking has become a way of life.

B. Multitasking often leads to efficiency decline.

C. Multitasking exercises need to be improved.

D. Multitasking enables people to remember things better.

On a cold evening I was waiting for a taxi in New York. About 5 minutes later, I was picked up by a driver, and he said how horrible some people were. I knew there was a part of me that wanted to be silent, but I had to listen out of kindness.

The man told me that he had just come from JFK Airport without a customer. Over the course of that taxi ride, what started as anger changed slowly and he mentioned that he had read an article which said that the happiest people are the ones that give, so he hoped he’d have more chance to give in his life. I was really starting to enjoy being with this man.

As we arrived at the place where I wanted to go, I paid my money by credit card. I pulled out an extra $20 and said, “Sir, since we’ve been talking about giving this whole time, I want to share that feeling with you. I’ve already paid my money, but here’s an extra little bit. You can tell the next passenger in this taxi that their ride is a gift from another.”

I thought I was pretty cool at this point. But he turned toward me, tears in his eyes, and he said, “Sir, I have a better idea. You give that $20 to a homeless person around here and I will give the next passenger a free ride myself.”

It was a great honor meeting that man and learning the lesson of how everyone gives and adds joy to another with their generosity.

According to the text, when the author got in the taxi, the taxi driver was________.

A. angry            B. nervous      C. worried      D. regretful

The author gave the driver an extra $20 in order to_________.

A. help him to get out of trouble       B. know what he was really like

C. experience the joy of giving     D. learn how to get along with others

What can be inferred from the taxi driver’s words in Paragraph 4?

A. A driver should be willing to help. 

B. People should understand each other.

C. The driver was deeply moved.    

D. One needs to keep an optimistic attitude (樂觀態度).

What would be the best title for the text?

A. A cold evening in New York       B. Learning from a taxi driver

C. A gift to a generous stranger        D. Always being a happy person

科目:高中英語 來源:2011-2012學年天津市高三年級第一次月考英語題 題型:閱讀理解

When women sit together to watch a movie on TV, they usually talk simultaneously(同時的)about a variety of subjects, including children, men, careers and what' s happening in their lives. When groups of men and women watch a movie together, the men usually end up telling the women to shut up. Men can either talk or watch the screen -- they can' t do both -- and they don' t understand that women can. Besides, women consider that the point of all getting together is to have a good time and develop relationships -- not just to sit there like couch potatoes staring at the screen.

During the ad breaks, a man often asks a woman to explain the plot and tell him where the relationship between the characters is going. He is unable, unlike women, to read the subtle body language signals that reveal how the characters are feeling emotionally. Since women originally spent their days with the other women and children in the group,  they developed the ability to communicate successfully in order to maintain relationships. For a woman, speech continues to have such a clear purpose: to build relationships and make friends. For men, to talk is to relate the facts.

Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a means of bonding. A woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours.

There is no convincing evidence that social conditioning, the fact that girls' mothers talked them more, is the reason why girls talk more than boys. Psychiatrist Dr Michael Lewis, author Social Behaviour and Language Acquisition, conducted experiments that found mothers talked to and looked at, baby girls more often than baby boys. Scientific evidence shows parents respond the brain bias of their children. Since a girl' s brain is better organized to send and receive speech, we therefore talk to them more. Consequently, mothers who try to talk to their sons are usually pointed to receive only short grunts in reply.

1.While watching TV with others, women usually talk a lot because they       

A.are afraid of awkward silence with their families and friends

B.can both talk and watch the screen at the same time

C.think they can have a good time and develop relationships

D.have to explain the plot and body language to their husbands

2. After a vacation with her girlfriend, a woman would talk to her again on the phone for hours in order to              .

A.experience the happy time again

B.keep a close tie with her

C.recommend her a new scenic spot

D.remind her of something forgotten

3.What does the author want to tell us most?

A.Women' s brains are better organized for language and communication

B.Women love to talk because they are more sociable than men.

C.Men do not like talking because they rely more on facts.

D.Social conditioning is not the reason why women love talking.

4.Which of the following would be the best title for the passage?

A.Women Are Socially Trained to Talk

B.Talking Maintains Relationships

C.Women Love to Talk

D.Men Talk Differently from Women.
