题目内容

A new study has found the amount of antibiotics（抗生素）given to farm animals is expected to increase by two-thirds over the next 15 years.Researchers are linking the growing dependence on the drugs to the increasing need for meat,milk and eggs.However,the drugs could quicken the development of antibiotic-resistant infections（感染）.Such infections are already a major public,health concern in the United States.

The World Health Organization notes when people stop living in poverty（贫困）,the first thing they want to do is eat better,rather than earn more money.For most people,that means their diet should contain more meat.With the rapid development of Asia,people there are eating nearly four times as much meat,milk and other milk products as they did 50 year ago.

To meet the need,farmers have put many animals into smaller spaces.As the animals are crowded together,the easiest way to deal with some of the problems d crowding is to give them antibiotics.It's clear that antibiotics help animals stay healthy in a crowded environment and grow faster.But bacteria can develop resistance to the drugs gradually.

Nowadays,doctors find antibiotics that once worked against the infections no longer work.The bacteria have learned ways to fight against the drugs.The heavy use of antibiotics in animals is responsible for the growth of antibiotic resistance worldwide.In the United States,at least two million people get drug-resistant infections each year and at least 23,000 die from an infection.

Europe has banned the use of antibiotics to increase animal growth.And the United States is hoping to persuade farmers to stop using antibiotics for that purpose.

1.What accounts for the increasing amount of antibiotics given to farm animals?

2.What do most people want to do first when they get rid of poverty according to the WHO?

A. Making a lot of money. B. Focusing more on health.

Habits, whether good or bad, are gradually formed. When a person does a certain thing again, he is driven by some unseen force to do the same thing repeatedly, then a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible, to get rid of. It is therefore very important that we should pay great attention to the formation of habits. Children often form bad habits, some of which remain with them as long as they live. Older persons also form bad habits lasting as long as they live, and sometimes become ruined by them.

There are other habits which, when formed in early life, are of great help. Many successful men say that much of their success has something to do with certain habits in early life, such as early rising, honesty and so on.

Among the habits which children should not form are laziness, lying, stealing and so on. These are all easily formed habits. Unfortunately older persons often form habits which could have been avoided.

We should keep away from(远离) all these bad habits, and try to form such habits as will be good for ourselves and others.

A. Good habits

B. Bad habits

C. Both good habits and bad habits

D. Either good habits or bad habits

C. to form such habits as will be good; to get rid of good habits

D. to get rid of bad habits; to form good habits

4.Why should we pay much attention to the formation of habits?

A. Because habits are of great help to every one of us.

B. Because a man can never get rid of a habit.

C. Because it's hard and sometimes even impossible to throw away bad habits.

D. Because we are forced to do them again and again.

We are all called upon to make a speech at some point in life, but most of us don’t do a very good job.1..

So, you have to give a speech—and you are terrified. You get nervous, you forget what you want to say, you stumble over words, you talk too long, and you bore your audience. Later you think, “Thank Goodness, it’s over. I’m just not good at public speaking. I hope I never have to do that again.”

Cheer up! 2.. Here are some simple steps to take the pain out of speech making. Ask yourself the purpose of your speech. What is the occasion? Why are you speaking? Then, gather as many facts as you can on your subject. Spend plenty of your time doing your research. Then spend plenty of your time organizing your material so that your speech is clear and easy to follow. Use as many examples as possible, and use pictures, charts, and graphs if they help you make your points more clearly. 3.. Don’t talk down to them. Treat your audience with respect. They will appreciate your thoughtfulness.

Just remember: Be prepared. Know your subject, your audience, and the occasion. Be brief.

4. . And be yourself. Let your personality come through so that you make person-to-person contact with your audience. If you follow these simple steps, you will see that you don’t have to be afraid of public speaking. In fact, you may find the experience so enjoyable that you volunteer to make more speeches! You’re not convinced yet? 5..

A. It doesn’t have to be that bad.

B. Take several deep breaths before your speech.
