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.
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 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.
3.People tend to make mistake 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

The term ''helicopter parents'' refers to ''a style of parents who are over focused on their children''.
Helicopter parents are always making a big effort to provide children with every opportunity to succeed, from baby steps at age I, homework at age 8, college application at age 18, employment issues at age 25 to family problems at age 30, 40 or even older. They constantly (不断地) shadow the child, always directing his behavior, allowing him zero alone time.
Helicopter parenting can develop for a number of reasons. Worries about the economy, the job market, and the world in general can push parents toward taking more control over their children’s life in an attempt to protect them. Adults who felt unloved or ignored as children can overcompensate (对……补偿过多) with their own children. When parents see other over-involved parents, it can cause a similar response. They feel that if they don t involve themselves in their children’s lives, they are bad parents.
The main problem with helicopter parenting is that it can backfire. To give an example, the house where Mary lived with roommates was broken into and things were stolen. Mary called the landlord to install (安装) an alarm system, but before she could finish the negotiations (协商), her mother rushed in and demanded action. ''I felt like my mother ruined my communication with our landlord. We could have gotten it done ourselves. She was well intended but only made me feel annoyed and defeated, '' says Mary.
Obviously, overparenting is motivated with the idea of doing good things but it does the exact opposite. In the long run parents are in fact damaging their child's basic skills to deal with matters independently. It makes the child feel lacking in confidence, less competent in dealing with the stresses of life on their own. They're winning the battle, but in fact losing the war.
1.What's the purpose of helicopter parents’ overparenting?
A.To make their children not ignored.
B.To help their children find a good job.
C.To do something good for their children.
D.To get rid of the pressure from other parents.
2.What does the underlined word ''backfire'' in Paragraph 4 probably mean?
A.Make an unwanted effect. B.Get a lot of support.
C.Set fire in the backyard. D.Help to be independent.
3.What can we learn from the passage?
A.Children who have helicopter parents live a hard life.
B.Helicopter parenting only happens to very young children.
C.Helicopter parents do their children great harm in the long run.
D.Helicopter parents can protect their children against all problems.
4.What will possibly be discussed in the following paragraph?
A.The bad effects of helicopter parenting.
B.How we can avoid being helicopter parents.
C.Different opinions about helicopter parenting.
D.The reasons for the development of helicopter parents.

Composer David Cope is the inventor of a computer program that writes original works of classical music. It took Cope 30 years to develop the software. Now most people can't tell the difference between music by the famous German composer J.S.Bach(1685-1750)and the Bach-like compositions from Cope's computer.
It all started in 1980 in the United States, when Cope was trying to write an opera. He was having trouble thinking of new melodies, so he wrote a computer program to create the melodies. At first this music was not easy to listen to. What did Cope do? He began to rethink how human beings compose music. He realized that composers' brains work like big databases. First, they take in all the music that they have ever heard. Then they take out the music that they dislike. Finally, they make new music from what is left. According to Cope, only the great composers are able to create the database accurately, remember it, and form new musical patterns from it.
Cope built a huge database of existing music. He began with hundreds of works by Bach. The software analyzed the data: it broke it down into smaller pieces and looked for patterns. It then combined the pieces into new patterns; Before long, the program could compose short Bach-like works. They weren't good, but it was a start.
Cope knew he had more work to do---he had a whole opera to write. He continued to improve the software. Soon it could analyze more.complex music. He also added many other composers, including his own work, to the database. A few years later, Cope's computer program, called “Emmy”, was ready to help him with his opera. The process required a lot of collaboration(合作) between the composer and Emmy. Cope listened to the computer's musical ideas and used the ones that he liked. With Emmy, the opera took only two weeks to finish. It was called Cradle Falling, and it was a great success! Cope received some of the best reviews of his career, but no one knew exactly how he had composed the work.
Since that first opera, Emmy has written thousands of compositions. Cope still gives Emmy feedback(反馈) on what he likes and doesn't like of her music, but she is doing most of the hard work of composing these days!
1.What led David Cope to invent software?
A. He had difficulties in writing an opera.
B. He dreamed of developing software.
C. He wanted to help composers.
D. He was fond of classical music.
2.What do we know about David Cope?
A. His Cradle Falling wasn’t popular.
B. He had kept on improving his software.
C. He composed Bach-like works well at the beginning.
D. He has shifted his attention to invent different software.
3.It can be learnt from the text that _______.
A. Cope’s database includes Bach’s works only.
B. Bach’s music helped Cope a lot.
C. Cope is a computer programmer.
D. Emmy did much more work than Cope in composing.
4.What is the best title for the text?
A. The Invention of a Software for Creating Music
B. Ways to Create a Music Database
C. David Cope--a Music Genius
D. How to Start Creating Music
