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). 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 (拨电话) 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.

Passage Three
No one knows exactly how many disabled (残废的) people there are in the world, but estimates suggest the figure is over 450 million. The number of disabled people in India alone is probably more than double the total population of Canada.
In the United Kingdom, about one in ten people have some disability. Disability is not just something that happens to other people. As we get older, many of us will become less mobile (可动的), hard of hearing or have failing eyesight.
Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many progressive disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form. of a mental illness. All are affected by people's attitude towards them.
Disabled people face many physical barriers. Next time you go shopping or to work or visit friends, imagine how you would manage if you could not get up steps, or on to buses and trains. How would you cope if you could not see where you were going or could not hear the traffic? But there are other barriers: prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through, so it is important to draw attention to these barriers and show that it is the individual person and their ability, not their disability, which counts.
41. The first paragraph points out that ______.
A. it is possible to get an exact figure of the world's disabled people
B. there are many disabled people in the world
C. the number of disabled people in India is the greatest
D. India has not much more disabled people than Canada
