To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount．That is according to a study published this Monday in the Public Library of Science Medicine Journal．
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't．
“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ” said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”
Study participants（參與者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．
“We can't say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what's theoretically（理論上地）possible．”
“Most people know that things like a good diet matter and that smoking isn't good for them, ” Susan Jebb said．“We need to work on providing people with much more practical support to help them change．”

T-shirts out; uniforms in
School uniforms（制服） are becoming more and more popular across the U.S.A. That’s no surprise, because they offer many benefits. They immediately end the powerful social sorting and labeling (標(biāo)記) that come from clothing. If all students are dressed in the same way, they will not pay too much attention to their clothing, and some of them will not be laughed at for wearing the “wrong” clothes.
Some people are against the strict rule of school uniforms, but they do not realize that students already accept a kind of rule — wanting to look just like their friends. The difference is that the clothing students choose for themselves creates social barriers(障礙); school uniforms tear those barriers down.
As in other places, uniforms remind the wearers of their purposes and duties. For example, when a man or woman puts on a police uniform, he or she becomes, for a time, the symbol (象征) of law and order. The uniform means to the wearer his or her special duties and sends the same message to everyone the wearer meets. People with different jobs wear uniforms of one kind or another. For students, the school uniform reminds them that their task for the six or seven hours they are in school is to get an education.
Some parents are unhappy about uniforms, saying that school uniforms will affect their children’s “creativity.” First, the clothes students choose to wear do not necessarily express their individuality (個性). They just copy their classmates. Second, students have the rest of the day to be as creative as they like. While they’re in school, their job is to master reading, writing, and maths; this should take up all the creativity they have. Mastery of those skills will be good for the students to build up their creativity in every way.
【小題1】From the passage we learn that uniforms in general       .

A．prevent the wearers from being laughed at
B．help the wearers keep their duties in mind
C．a(chǎn)re seen as a symbol of power
D．help to create social barriers
【小題2】Some people are against school uniforms because       .
A．they fail to realize that students have accepted the uniforms
B．they believe that uniforms will make students less creative
C．they don’t agree that uniforms can remove social barriers
D．they think that school uniforms are too popular
【小題3】The author would probably agree that       .
A．it makes no difference whether to wear school uniforms or not
B．students’ individuality may not come from school education
C．students’ creativity is related to the clothes they choose
D．school uniforms help to create equality among students
【小題4】School uniforms are becoming more and more popular and important because _____
A．they can stop the powerful social sorting and labeling.
B．if all students are dressed in the same way, they will not pay too much attention to their clothing.
C．uniforms can remind the wearers of their purposes and duties
D．school uniforms will affect their children’s creativity.

Online Communication

In an age when technology moves faster than most can keep up with, a small group of people still remain in the time of old-fashioned letter. Frankly speaking, I was once certain that traditional letters could never be replaced by other means of communication.

But a story about online communication changed my mind.

An old man, who suffered a lot from Parkinson’s disease, was not able to talk clearly and could hardly write his name. Living totally alone, he managed to keep in touch with nearly all the members of his family. How did he achieve this? He clicked out words on his computer keyboard.

I, therefore, managed to get an E-mail box as soon as the opportunity came. My life changed. E-mail, and all online communication, is something truly different. It has capabilities（能力） that few other products can match.

E-mail is convenient. It takes less time with its fast speed and 24-hour connection. The slow postal service is no match. If you wouldn’t want to have a face-to-face talk with your manager, you might talk with him through E-mail even if you are in the same office.

Naming all the good things about online communication is not easy. But wait. E-mail can be inconvenient. It can waste time and energy. Just think what may happen when you take a short vacation and return to find your e-mail box filled with 200 unread messages. You could easily spend half a day clearing junk ads.

Then, online communication will keep us staying at our computer while it connects us to distant strangers. Once we throw ourselves into the machine, we may forget the human touches we once held so dear. I’m sure there is and always will be a place for the old-fashioned letter, phone call, and face-to-face meeting… even in the world of modern communication.

As I listen to the sound of the modem(調(diào)制解調(diào)器), I was excited at stepping out to the outside world but, at the same time, I sensed a loss of control over something valuable in my personal life.

1.What is the most probable meaning of the underlined word “junk” in paragraph6?

A. old and useless   B. New and useful   C. Short but valuable     D. Long but clear

2.What does the writer think of online communication?

A. It should replace old-fashioned letters completely.

B. It is perfect and always does good to you.

C. It is extremely useful and convenient, but it may be inconvenient or even harmful.

D. It does more harm than good.

3.What caused the writer to become interested in E-mail and online communication?

A. The sound of the modem.           B. His own illness.

C. The changing of his life.            D. A sick old man’s experience.

4.According to the writer, traditional means of communication will never disappear because ________.

A. they are convenient and popular though they are slow

B. they help to keep the friendly relationship between people

C. most people cannot keep up with the development of technology

D. modern means of communication does too much harm

5.How did the sick old man keep in touch with his family members?

A. With the help of his computer.        B. By writing letters with his pen.

C. By making telephone calls.          D. By visiting them regularly.

Whether they’re project documents, trade journals, blogs, business books or ebooks, most of us read regularly as part of our jobs, and to develop our skills and knowledge.

But do you ever read what should be a useful document, yet fail to gain any helpful information from it? Or, re-read something several times to get a full understanding of the content? If so, look at the following strategies (策略) that will help you read more effectively.

●Think About What You Want to Know

Before you start reading anything, ask yourself why you’re reading it. Are you reading with a purpose, or just for pleasure? What do you want to know after you’ve read it? Once you know your purpose, you can examine the resource (資源) to see whether it’s going to help you.

Ask yourself whether the resource meets your needs, and try to work out if it will give you the right amount of knowledge. If you think that the resource isn’t consummate, don’t waste time reading it.

●Know How Deeply to Study the Material

Where you only need the shallowest knowledge of a subject, you can skim material. Here you read only chapter headings, introductions, and summaries.

If you need a moderate (中等的) level of information on a subject, then you can scan the text. This is when you read the chapter introductions and summaries in detail. You can then speed read the contents of the chapters, picking out and understanding key words and concepts.

Only when you need full knowledge of a subject is it worth studying the text in detail (細節(jié)). Here it’s best to skim the material first to get an overview of the subject. This gives you an understanding of its structure, into which you can then fit the detail gained from a full reading of the material.

1.Why should we know our purpose before reading?

A．Because we can develop our skills and knowledge.

B．Because we can get a full understanding of the content.

C．Because we can avoid re-reading something several times.

D．Because we can check it out whether the material will be helpful.

2.What does the underlined word “consummate” in the 5th paragraph mean?

A．Legal.

B．Natural.

C．Perfect.

D．Formal.

3. According to the depth to study the material, how many reading strategies are mentioned?

A．2.

B．3.

C．4.

D．5.

4.The best title for this passage should be ______.

A．Reading Strategies

B．Think About What You Want to Know

C．Know How Deeply to Study the Material

D．How to Develop our Skills and Knowledge
