題目列表(包括答案和解析)

Could a grizzly bear move to your neighborhood? If you live in the U.S. West, the answer may be yes. People and grizzly bears are living closer together now.

The grizzly bear is one of the largest meat-eating land animals in North America. In the early 1800s, about 50,000 grizzly bears lived there. Today there’re far fewer bears. Settlers built cities and roads where bears lived. Many bears were hunted and killed. Now only 1,200 to 1,400 grizzly bears have remained.

In and around Yellowstone National Park, grizzly bears have been making a comeback because of people’s efforts to protect them. Some bears are moving to areas where people live. People are also moving into grizzly countries.

People there have to learn how to live with their new, furry (毛皮的) neighbors peacefully. If someone leaves their barbecue grill(烤肉架)out overnight, or leaves their pet food or rubbish where a bear can get it, the bear will learn to come to their house for food. Grizzly bears that learn to eat people’s food can become dangerous, and they often have to be killed or moved. Also, it’s important not to surprise a grizzly. Besides, if you are hiking in a grizzly country, you should go with others and make a noise to make bears hear your coming and get out of the way. You may not want to invite grizzly bears to your next neighborhood party, but with a little effort, grizzly bears and people can live together peacefully.

Why does the number of grizzly bears get smaller, according to the text?

A. Settlers’ buildings break the balance of their living environment.  

B. Land for them to live on is limited and they are hunted in large numbers.

C. Yellowstone National Park wants to control the number of them.

D. Living closer to humans makes them die from serious diseases.

How many suggestions are made for people to live with bears peacefully?

A. One.          B. Two.       C. Three.          D. Four.

Compared with the early 1800s, the number of grizzly bears has got smaller by ______.

A. exactly 26﹪          B. over 36﹪   C. nearly 64﹪   D. about 96﹪

Which of the following statements is TRUE according to the passage?

B. It is certain that grizzly bears and people can live together peacefully.

C. Grizzly bears are protected only in and around Yellowstone National Park.

Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover(更換)rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.

The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."

Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components(部件)in many electronic products contain harmful chemicals that pollute ground water and the environment.

At present , the U.S. has no federal law for the disposal (處理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (過(guò)濾) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."

What does the underlined word "retrieve" (paragraph 2) probably mean?

A. look into   B. take apart   C. get back   D. throw away

What of the following statements is true according to the passage?

A. The U.S. has strict national laws for dealing with e-waste.

B. Third world countries import e-waste to get valuable parts, which is a safe and easy way to make money.

C. The way uneducated workers deal with old computers does great harm to the environment as well as to their own health.

D. More and more electronic waste is being wasted and thrown away mainly because of people's bad habits.

What is the purpose of writing the passage?

A. To attract more people's attention to e-waste.

B. To call on people not to throw away e-waste anywhere.

C. To tell people what e-waste is and how to deal with it well.

D. To warn people to break away from the electronic industry.

The next paragraph probably concerns ___.

A. how to deal with e-waste properly

B. how to protect ourselves from harm by e-waste

C. How to slow down the development in the electronic industry

D. how to make full use of e-waste
