How do people traditionally manufacture (制造) things? They usually start with a sheet of metal, wood or other material and cut, drill (鉆) and shave it to create a desired shape. Sometimes, they use a mold (模具) made of metal or sand, pour liquid plastic or metal into it and let it cool to create a solid part.

Now, a completely different method is gaining popularity.

On Oct. 9, 2013, London Science Museum kicked off its new exhibition, 3-D: Printing the Future, with over 600 3-D printed objects on display, including space probes (探測器), toy dolls and even human organs – basically any product you can think of, reported Live Science.

You might find it hard to believe that an object can actually be “printed out” like a picture. But it is not that hard to understand how it works. Just as a traditional printer sprays (噴灑) ink onto paper line by line, modern 3-D 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 3-D printer uses are mainly plastic, resin (樹脂) and certain metals. The thinner each layer is – from a millimeter to less than the width of a hair – the smoother and finer the object will be. And objects always come out in one piece, sparing you the trouble of putting different parts together afterward.

For example, 10 years ago a desktop 3-D printer might have cost ￡20,000 (200,000 yuan), while now it costs only about ￡1,000, according to the BBC. In fact, 3-D printers have been around for some time, but until recently they hadn’t been very popular since few people could afford them. Last year, though, saw a big decrease in the price of 3-D printers.

However, as 3-D printing technology becomes more commonplace, it may trigger certain problems. One of them is piracy (盜版). “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?” an expert on 3-D printing told Forbes News.

Even more frightening, the world’s first 3-D printed gun was successfully fired in the US in May of this year, which means that 3-D printing could potentially give more people access to weapons.

1.According to the article, in the future, 3-D printing technology will probably ______.

A. change the way people make products

B. be applied as widely in our daily lives as computers

C. forbid many countries to make purchases of weapons

D. take the place of normal printers and save lots of energy

B. 3-D printing technology came to be used in various fields.

C. The world’s first 3-D printed gun was successfully made.

D. The 3-D printer became more affordable for consumers.

3.What is the author’s attitude toward 3-D printing technology?

A. Amused. B. Objective.

C. Supportive. D. Negative.

One day my 13-year-old daughter told me that she was going to spend the afternoon at her friend Jesse’s house. I didn’t doubt it until I called Jesse’s number to remind Liz that it was her turn to walk the dog, and Jesse’s mom picked up the phone and said, “I thought she and Jesse were planning to be at your house.” It turned out that the two of them had decided to hang out at a coffee shop instead. When I questioned my daughter, she replied coldly, “What’s the big deal? You’re such a psycho(精神變態(tài)者).”

Can you say it is right or wrong for them to behave like that? Their changeable personalities leave you feeling angry and guilty at the same time. In fact, if your kids don’t annoy you from time to time, you’re not doing your job.

“There’s nothing wrong about being angry with your child,” Says Laurence Steinberg, Ph.D., author of The 10 Basic Principles of Good Parenting. “Conflict is natural when your innocent, lovely child turns into an adolescent who can hardly tolerate (忍受) you. It’s part of the process of separation.” Kids insisted on their individuality with behavior to purposely drive you crazy. It’s their way of saying, “I am my own person” -- but doing it in a context that’s safe and that has clear limits.

So when your little darling changes into a silent person who still expects meals, clothing, and transportation, don’t panic. Here’s how to handle some common problems without losing your temper or your self-respect.

1.It can be learned from the first paragraph that ________.

A. Jesse’s mother told a lie

B. the writer was too sensitive

C. Liz told a lie to her mother

D. the writer’s daughter stayed at Jesse’s house

2.By saying “In fact, if your kids don’t annoy you from time to time, you’re not doing your job”, the writer probably means that _________.

A. when you are doing a job, your kids shouldn’t annoy you

B. parents should be responsible for children’s bad behavior

C. parents shouldn’t tolerate their children’s bad behavior

D. it’s understandable for kids to annoy their parents

3.What’s the main idea of the third paragraph?

A. It’s right for parents to be angry with their children.

B. It’s allowed for children to do anything as they like.

C. It’s bad behavior for children to drive their parents angry.

D. It’s normal for adolescents to go against the wishes of their parents sometimes.

4.What would the writer state in the following paragraphs?

A.How to be good parents.

B.How to be good children.

C.Rules for children to follow.

D.How to deal with adolescents’ common problems properly.

It was Saturday when the entire summer world was bright and fresh. Tom looked at the fence, which was long and high, feeling all enthusiasm leaving him. He dipped his brush into the whitewash before moving it along the top board of the fence. He knew other boys would arrive soon with all minds of interesting plans for this day. As walking past him, they would tease him for having to work on a beautiful Saturday—which burnt him like fire.

He, putting his hands into his pockets and taking out all he owned with the expectation of letting someone paint, found nothing that could buy half an hour of freedom. At this dark and hopeless moment, a wonderful idea occurred to him, pouring a great bright light into his mind. He took up his brush and continued to work pleasantly with calm and quietness.

Presently, Ben Rogers came in sight—munching an apple and making joyful noises like the sound of a riverboat as he walked along. Tom went on whitewashing, paying no attention to the steamboat. “Hello!” Ben said, “I’m going swimming, but you can’t go, can you?”

No answer. Tom moved his brush gently along the fence and surveyed the result. Ben came nearer. Tom’s mouth watered for Ben’s apple while he kept painting the fence.

Ben said, “That’s a lot of work, isn’t it?”

Tom turned suddenly saying “Here you are! Ben! I didn’t notice you.”

“I’m going swimming,” Ben said. “Don’t you wish you could go? Or would you rather work?” Tom said, “Work? What do you mean ‘work’?”

“Isn’t that work?” Tom continued painting and answered carelessly, “Maybe it is, and maybe it isn’t. All I know is it suits Tom Sawyer.”

“Do you mean that you enjoy it?”

“I don’t see why I oughtn’t to enjoy it.”

“Does a boy have a chance to paint a fence frequently” said Tom.

Ben stopped munching his apple.

Tom moved his brush back and forth—stepped back to note the effect—added a little paint here and there. Ben watched every move, getting more and more interested, more and more absorbed. After a short time, he said, “Tom, let me whitewash a little.”

Tom seemed to be thinking for a moment before he said, “No, Aunt Polly wants this fence to be perfect. If it was the back fence, maybe you could do it. But this fence beside the street is where everybody can see it. It has to be done right.”

“Oh, come on, let me try. I’ll be careful. Listen, Tom. I’ll give you part of my apple if you let me paint.” “No, Ben, I’m afraid—” “I’ll give you all the apple!”

Tom handed the brush to Ben with unwillingness on his face but alacrity in his heart. While the riverboat worked and sweated in the hot sun, Tom, an artist sat in the shade close by, munching his apple, and planning how he could trick more of the boys.

Before long there were enough boys each of whom came along the street; stopped to laugh but soon begged to be allowed to paint. By the middle of the afternoon, Tom had got many treasures while the fence had had three layers of whitewash on it. If he hadn’t run out of whitewash, he would have owned everything belonging to the boys in the village.

Tom said to himself that the world was not so depressing after all. He had discovered a great law of human action: in order to make a man cover a thing, it is only necessary to make the thing difficult to attain.

Many people often lose their chance to live life to the fullest because of procrastination, which means that they always delay doing something that must be done at once. Moreover, because they often put off their plans till “tomorrow”, they are less likely to achieve their goals and will give up their dreams and goals finally. As a result, we can say that procrastination is the enemy of a progressive lifestyle.

Now that we know procrastination is something bad, why do some people not take immediate action? Well, there are some things that result in procrastination. Depending on someone else rather than doing by oneself is one of the things. Whenever you wait for something to happen before you act, you make it easier to delay your goals and dreams until “someday”. Another cause of procrastination is that people do not value each moment in their day. Actually, it’s surprising how much you can do if you just decide to do little things with the little time you have. Also those who often procrastinate can always find a good reason for something they refuse to do at once.If you are one of those who often delay, then it’s time for you to make a decision to act now because things happen only when we decide to act. Get down to doing something like losing weight, saving money or spending more time with family. Don’t let these things continue to be a desire for you to do “someday”, but make a decision to do it now.

Once you have made your decision, write down the plan and take action immediately. Making plans can help you think carefully about how you are going to do what you need to do. After understanding how to do what you want to do, get doing with the plan. It doesn’t matter how small the move you make is as the little things you do accumulate（累積）over time and move you to be closer to your goals. So, don’t wait until tomorrow; instead, start now! Just make use of every moment you have to do something that is helpful in realizing your dreams and goals.

Here is a challenge that will also move you to be closer to your dreams and goals if taken seriously. Make a list of ten things you have been putting off. It could be anything from getting a health examination, calling a friend or family member, to getting the car fixed and cleaning up the garbage, etc. And then try to develop the habit of doing them immediately!
