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.
49. 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.

Maybe it is true that we don't know what we have got until we lose it, but it is also true that we don' t know what we have been missing until it arrives. Giving someone all your love is never an assurance that they will love you back. Don’t expect love in return; but be content that love has grown in your own heart.
It takes an hour to like someone, a day to love someone, but it takes a lifetime to forget someone. Don’t rely on one's appearance; it can deceive. Don’t rely on wealth; even that fades away. Rely on someone who makes you smile, because it takes only a smile to make a dark day seem bright. There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them. Dream what you want to dream; go where you want to go; be what you want to be, because you have only one life and one chance to do all the things you want to do. May you have enough happiness to make you sweet, enough trials to make you strong, enough sorrow to keep you human, enough hope to make you happy.
Always put yourself in others' shoes. If you feel that it hurts you, it probably hurts others, too. The happiest of people don't necessarily have the best of everything; they just make the most of everything that comes along their way. Happiness waits for those who cry, those who have been hurt, those who have searched, and those who have tried, for only they can appreciate the importance of people who have touched their lives.
The brightest future will always be based on a forgotten past. You can't go on well in life until you let your past failures and heartaches go off. When you were born, you were crying and everyone around you was smiling. Live your life so that when you die, you are the one who is smiling and everyone around you is crying.

C
Is there someone you hate? Well, maybe you don’t really hate them. But you get really angry every time you think of them. If you don’t let this anger go, it can turn into bitterness (痛苦).
Bitterness appears when we can’t forgive (原谅) someone who has hurt us or made us angry. Someone might say or do something that hurts us. But instead of controlling the anger, we keep it deep inside. Before long, a bitter feeling begins to grow. We may think we’re hurting that person by criticizing (指责) him or her often, but we’re really only hurting ourselves.
Bitterness can not only lead to serious health problems such as heart disease, but also hurt our relationships with friends and family members. No one enjoys being around an angry person for very long.
If you see bitterness in your life, here are some ways to deal with it.
l Accept it
Instead of trying to deny your anger, make it clear to yourself and accept it. See your anger for what it is and quickly deal with it.
l Stop making excuses for it
You may feel you have a right to be angry. You may think you’re right and the other person is wrong. You may even secretly enjoy making the other person look bad. But in the end, bitterness hurts you much more than the other person. The bitterness will hold you back, and the other person will go on with his or her life.
l Forgive and forget it
You probably can’t completely put the anger out of your mind. But you can decide to forgive the other person. Forget it and move on. You’ll enjoy better health and peace of mind.
66. According to the passage, we might get angry when someone __________.
A. holds us back B. forgets us C. doesn’t like us D. does hurt us
