English words don’t stay the same. People need new words for new ideas and new inventions. Some new words come into use, and some old words are used in a new way.

English can change by borrowing words from other languages. The word “tomato” was borrowed from Mexico, and “tea” came from China, and so on. Now a great many new space and science words are being borrowed from other countries, too. New words can be created in other ways. For example, some can be created by adding two words together. “Weekend” and “cookbook” are made up of two parts. Sometimes new words are shorter forms of older words. The word “photo” was made from “photograph” by cutting off the end of the longer word. “Plane” was made by cutting off the front part of “airplane”. The names of people and products can become new words. Our “sandwich” was named after a man named Sandwich and “sello(透明胶带)” was a name given by the company that first made the product.

A. people use old words in a new way

Hi, everybody. Over the past couple months, most of the political headlines you’ve read have probably been about the government shutdown and the launch of the Affordable Care Act. And I know that many of you have rightly never been more frustrated with Washington.

But if you look beyond those headlines, there are some good things happening in our economy. And that’s been my top priority since the day I walked into the Oval Office.

After decades in which the middle class was working harder and harder just to keep up, and a punishing recession that made it worse, we made the tough choices required not just to recover from crisis, but to rebuild on a new foundation for stronger, more durable economic growth.

Five years later, we have fought our way back. Our businesses have created 7.8 million new jobs in the past 44 months. Another 200,000 Americans went back to work last month.

The American auto industry has come roaring back with more than 350,000 new jobs – jobs churning out and selling the high-tech, fuel-efficient cars the world wants to buy. And they’re leading the charge in a manufacturing sector that has added jobs for the first time since the 1990s – a big reason why our businesses sell more goods and services “Made in America” than ever before.

We decided to reverse our addiction to foreign oil. And today, we generate more renewable energy than ever, more natural gas than anybody, and for the first time in nearly 20 years, America now produces more oil than we buy from other countries.

We decided to fix a broken health care system. And even though the rollout of the marketplace where you can buy affordable plans has been rough, so far, about 500,000 Americans are poised to gain health coverage starting January 1st. And by the way, health care costs are growing at the slowest rate in 50 years.

And one more thing: since I took office, we’ve cut our deficits by more than half. And that makes it easier to invest in the things that create jobs – education, research, and infrastructure.

Imagine how much farther along we could be if both parties were working together. Think about what we could do if a reckless few didn’t hold the economy hostage every few months, or waste time on dozens of votes to repeal the Affordable Care Act rather than try to help us fix it.

In the weeks ahead, I’ll keep talking about my plan to build a better bargain for the middle class. Good jobs. A good education. A chance to buy a home, save, and retire. And yes, the financial security of affordable health care. And I’ll look for any willing partners who want to help.

Because of your hard work and tough sacrifices over the past five years, we’re pointed in the right direction. But we’ve got more work to do to keep moving that way. And as long as I’m President, I’ll keep doing everything I can to create jobs, grow the economy, and make sure that everyone who works hard has a chance to get ahead. Thanks, and have a great weekend.

1.Which of the following is not the reason for people’s frustration with the government?

A. The government shut down

B. Unemployment rate

C. The addiction to foreign oil

D. The launch of the Affordable Care Act

2.Why does the president mention more goods and services “Made in America”?

A. To show that American goods and services are very popular.

B. To indicate that American people should be dependent on themselves.

C. To show that the employment rate has been increased.

D. To show that American auto industry enjoys high technology.

3.What’s the meaning of the underlined word “repeal”?

A. To abolish B. To protect

C. To strengthen D. To weaken

4.According to the speech, which of the following can be implied?

A. American people have every reason to feel frustrated with the government.

B. Health care costs are growing at the slowest rate in 50 years.

C. The president feels sorry that the economy is not moving in the right direction.

D. Some government officials don’t agree with the president on the medical care system.

“When should I begin to acquire good habits?”a young boy asked his teacher.

“How old are you?” asked the teacher.

“Eight years old, sir.”answered the boy.

“Then you have just lost eight years,”the teacher replied.

There is no doubt that habits are formed at a very early age. When one is young, it is easy to acquire good habits.

Good habits are practices that help us in our daily life. The habit of brushing one’s teeth in the morning, for instance, keeps one’s teeth clean and prevents a bad smell which is unpleasant to others. Bad habits such as sticking one’s tongue out, biting one’s fingernails and picking one’s nose, are undesirable ways of behaving in front of others. If we want people to enjoy being with us, we should try to develop habits that are pleasant.

It is said, “We sow an act; we reap a habit. We sow a habit and we reap a character.” The habits we formed at an early age shape our character. Habits are like tributaries(支流) which flow into a river. The river is made up of all its tributaries; a person’s character is made up of all the habits that he or she has acquired over the years.

Food makes us feel good, but some people eat when they aren’t really hungry and eat to simply feel good. This kind of eating habit is called emotional eating, which does not affect adults but also young children. It isn’t a good thing.

A child’s eating habits can develop right from childhood. As we know, a baby cries out if he doesn’t get milk at the usual time of the day. However, sometimes parents immediately stick a bottle in a child’s mouth without trying to find out if the child is really hungry. In fact, children may cry for other reasons. Even as children grow up and start going to school, parents sometimes give them a chocolate bar if they become really unhappy. As the children further grow up, they may become used to having a snack whenever they’re upset or low.

Therefore, they’d like to eat an emotional snack when they have the feeling of unhappiness and boredom. Even when they don’t get high grades, aren’t popular at school or made fun of by others, they will want something to eat. After having the snack, they feel a lot better.

Emotional eating in young children is a thing that needs to be taken seriously. To protect your children from emotional eating, you should satisfy your child’s emotional needs in the best possible way. This includes spending time with your child every day, taking an interest in his school work, helping your child study, providing a health environment without tension at home, etc. Don’t make the child lose face by scolding him. Develop confidence in your child. Make your child eat enough once in a while. Reward him for his achievements.

All this will help your little one develop a healthy eating habit. And always remember love and care is the key to help you child out of trouble and grow up happily.
