The term “multitasking” was firstly used to describe a computer’s ability to do several tasks at one time. For many people, multitasking has become a way of life and even a key to success. Although checking e-mails while talking on a phone and reading the newspaper may be second nature for some people, multitasking can sometimes make us less productive(富有成效的), rather than more. Studies show that too much multitasking may bring anxiety and memory loss.
In order to multitask, the brain uses an area known as the prefrontal cortex(前额叶脑皮层). A research from volunteers performing multiple tasks shows that as they move 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 happened is that between the dialing and the answering, your mind moved to another thought or task, and then took that “moment” to come back. The research has also shown that for many volunteers, job efficiency(效率) drops while multitasking, compared to when they perform only one task at a time.
Multitasking is easy when at least one of the tasks 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 tried at the same 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. We may not notice new information coming in, so it never makes it into our memory. That is one of the main reasons we forget people’s names – even sometimes right after they have introduced themselves. Multitasking can also affect(影响) our relationships. If someone checks their e-mail while on the phone with a friend, they may appear absent-minded or disinterested. It can also cause that person to miss key information being passed on to them.
1.Which of the following words has the closest meaning to “anxiety”?
A.Stress B.Development C.Death D.Confidence
2.The writing purpose of this passage is to________.
A.describe the problems of multitasking B.discover the secrets of multitasking
C.tell the stories about multitasking D.explain the importance of multitasking
3.What can we learn about multitasking?
A.It is a way of life and the only key to success. B.It can be done easily by smart people.
C.It helps build a better relationship between friends. D.It has a close connection to our brain.
4.What can we infer(推断) from the passage?
A.Multitasking helps people remember things better.
B.More mistakes are made when tasks require little thought.
C.People get low job efficiency while managing several details at the same time.
D.People forgetting who to dial need to have a good rest.

Fashion is a term commonly used to describe a style of clothing worn by most people of a country. A fashion usually keeps popular for 1-3 years and then is replaced by another fashion. Even though there are a lot of changes in fashion, most people do not easily hope for the changes.
Nowadays more and more young people prefer following the fashion. On this phenomenon(现象), different people have different opinions. It is held that one should follow the fashion so as not to be looked down or seem strange. But it is also held that one should have his or her own judgement(判断).
Those who hold the first opinion think that society is progessing and one should get used to the changes. In their opinions, if everyone always follows the old fashion, there won’t be any change and naturally there won’t be much progress. However, those who hold the second view think that one shouldn’t follow the fashion without having his or her own judgement and characters.
As for me, I agree with the second opinion. Of course, it’s good for people to keep up with the fashion, but this is not to say that people should follow the fashion blindly(盲目地). If all the people follow the same fashion, there will be no variety and the whole society will be boring.
1.. The second paragraph mainly tells us ________.
A. what the fashon is about
B. different people have different opinions about the fashion
C. whether one should follow the fashion or not
D. more and more young people prefer following the fashion
2. According to those who hold the first view, why should one follow the fashion?
A. One should follow the fashion so that they won’t be looked down.
B. One should follow the fashion so that society is progressing.
C. One should follow the fashion so that people will have their own judgement.
D. One should follow the fashion so that society will be boring.
3..We can tell from the story that the writer thinks we should _________.
A. keep up with the same fashion
B. be against the fashion
C. say nothing about the fashion
D. follow the fashion by our own judgement
4.What is the best title for the passage?

The word, “photography”, was first used in 1839. It comes from the Greek words that mean “to write with light”. But photography could only give people static pictures. So scientists were trying hard to find ways to make pictures that can move. They made lots of experiments, but failed again and again. It was Eadweard Muybridge who finally succeeded. He was the first photographer to try this successfully. But how did he make it? It was an interesting story.
Back in 1872, people didn’t know exactly whether all four of a horse’s hooves (蹄) left the ground at the same time when it was running. A gentleman called Leland Stanford made a bet with his friend about it. Most people believed that a horse always had one hoof on the ground, or it would fall over. But Stanford didn’t think so.
At that time, it was hard to know who could win the bet, because a horse’s legs move so fast that it is impossible to tell just by looking. So they needed a way to record the movement of a running horse. Then Stanford offered $25,000 to the famous photographer, Muybridge, to help find the answer. In the beginning, Muybridge failed to get clear images, but he didn’t give up. He continued to improve his cameras. In 1878, after many experiments, he managed to get a sequence (连续) of 12 photos. One of them clearly showed that all four of the horse’s hooves were off the ground at the same time. And when the photos moved fast, people could see a horse running.

A. next year. B. at the same year.
C. after six years. D. after seventeen years.
4.Which is TRUE from the passage?
A. The word, “photography” means to make pictures that can move from the Greek words .

The word photography was first used in 1839. However, at that time the subject (被拍对象) had to keep still while a picture of it was taken. Few people had ever tried to take photos of moving subjects. The first man to do so was Eadweard Muybridge, a world-famous photographer. He created the first moving picture.

Most people believed that a horse always had one hoof on the ground, but Stanford didn’t think: so. Because a horse’s legs are moving so fast, it’s impossible to tell just by looking. Stanford needed a way to record the movement of a running horse. In 1872, Leland Stanford offered Eadweard Muybridge $25,000 to find the answer. Muybridge had no idea if he could successfully set up and perform an experiment to settle (解决) the bet, but he thought he should give it a try.
In 1878, after years of experiments, Muybridge got what he wanted. He had a sequence (连续) of 12 images (图像), and one of them clearly showed all four of the horse’s hooves were off the ground at the same time. In the end Muybridge collected his well-earned $25,000 from Stanford.
