See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting “print” on your computer. You might find it hard to believe that you could actually “print” an object like you would draw a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.

Instead of ink, the materials the 3D printer uses are mainly plastic, resin(樹脂) and certain metals. The thinner each layer is—from a millimetre to less than the width of a hair—the smoother and finer the object will be. This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.

Last year, though, saw a big change in the 3D printing industry—printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost ￡20,000, while now they cost only about ￡1,000, according to the BBC. Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of—flutes, bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.

However, as 3D printing becomes more common, it may bring about certain problems—such as piracy. “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3D printer, who will visit a retail store again？” an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun?

1.According to the article, in the future, the 3D printing technology will _______.

A. enable people to make better purchases online

B. change the way we make many products

C. be applied as widely in our daily life as computers

D. shorten the time it takes for people to get what they buy online

2.What happened in the 3D printing industry last year?

A. The 3D printing technology was taken out of the factory.

B. The 3D printing technology began to be used in various fields.

C. The 3D printer was used for medical treatment for the first time.

D. The 3D printer became more affordable for consumers(消費者).

3.What is the best title of the passage?

A. Great Demand for 3D Printers

B. Technology in the Future

C. Online Shopping Disappearing

D. Printing out Everything

4.How is the last paragraph developed?

A. By giving examples.

B. By making comparisons.

C. By analyzing the cause and effect.

D. By using figures.

What would it take to persuade you to exercise? A desire to lose weight or improve your figure? To keep you away from diseases? To live to a healthy old age? You'd think any of those reasons would be enough to get Americans exercising. Yet a vast majority of Americans have thus far failed to swallow the "exercise pill".

Now a research by psychologists strongly suggests it's time to think of current well-being（幸福）and happiness as motivators for exercise instead of future health, weight loss and body image.

Dr. Segar, one of the researchers, believes that immediate rewards are more motivating than distant ones. "People who say they exercise for the quality of life exercise more over the course of a year than those who say they value exercise for its health benefits." He said. '

Other studies have shown that what keeps people moving depends on age, sex and life circumstances. For those of college age, physical attractiveness typically heads the list of reasons to begin exercising, although what keeps them going seems to be the stress relief that a regular exercise program provides. The elderly, on the other hand, may get started because of health concerns. But often what keeps them exercising are the friendships and sense of community that may otherwise be missing from their lives. Improving daily well-being is the most influential factor for the women. Men indicate they are motivated by more distant health benefits, but this may be because men feel less comfortable discussing their mental health needs.

"Exercise should be encouraged but the emphasis on weight loss, disease prevention and healthy aging should be reduced." Dr. Segar concluded. "Exercise can make people feel more energetic, less stressed and, yes, happier."

1.What does the underlined part in Paragraph 1 mean?

A. Be free from diseases.

B. Take some diet pills.

C. Improve their figure.

D. Keep physically active.

2. According to the passage, which of the following persons may exercise more in a year?

A. Jane, who decides to lose weight.

B. David, who exercises for future health.

C. Mary, who enjoys exercising with her son..

D. Mark, who is suffering from a serious illness.

3.According to Paragraph 4, which group of people tends to exercise for friendship?

A. Men. B. Women. C. The elderly. D. College students.

4.What is the author mainly arguing in the passage?

A. Immediate rewards of exercise should be emphasized.

B. Distant benefits should be the motivators for exercise.

C. Feeling relaxed is more important than future health.

D. Men and women take exercise for different purposes.

閱讀短文內容，從短文后的選項中選出能填入空白處的最佳選項，選項中有兩項為多余選項。

Many kids and teenagers have cell phones in their hands. However, is it really necessary for them to have phones at school? Here are the pros and cons.

Pros

They can get in touch when necessary. The main benefit of having a phone is that your children can get in touch with you whenever they need to. 1. They can call the emergency services if necessary. If your children are in immediate danger, they can use their phones to call not only you but the emergency services. This is of great benefit and could potentially save your children’s lives.

2. As long as your children remember to do this , their phones won’t cause distraction(分心) in class. Giving them a standard instead of a smart-phone will also reduce the risk of distraction.

Cons

The latest smart-phones can almost double as a computer. It means they offer far more of a distraction to kids than they used to. 3. All these characteristics could disturb your children’s concentration (注意力) if they play with them in class.

Cellphones could interrupt lessons. Many children, even though they are asked to do so, forget to turn off their phones during lessons and their phones may make sounds. 4. Besides the distraction problem, cellphones can also be used to look up answers on the Internet. 5. The possibility of children having access to these during exams could be too attractive for them not to take advantage of.

A. Cellphones can be turned off or put on mute.

B. Children use ordinary phones instead of smart-phones.

C. This allows you to feel they are safe and easy to reach.

D. Without cellphones, campus life would be less colorful.

E. They have some other functions — a calculator and the ability to save notes.

F. This not only annoys other pupils, but also prevents them from learning well.

G. Nowadays, children can not only text and make calls with their phones, but also play games, surf the Internet and listen to music.
