In the United States alone, over 100 million cell-phones are thrown away each year. Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants. The electronic waste stream is increasing three times faster than traditional garbage as a whole.

Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste, the concentration (含量) of gold and other precious metals was higher in　 So-called e-waste than in naturally occurring minerals.

Electronic wastes also contain many poisonous metals. Even when the machines are recycled and the harmful metals removed, the recycling process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances to escape into the environment.

Creating products out of raw materials creates much more waste material, up to 100 times more, than the material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging(包装) it came in. Many wastes produced in the producing process are harmful as well.

The U.S. Environmental Protection Agency notes that most waste is dangerous in that “the production, distribution, and use of products — as well as management of the resulting waste — all result in greenhouse gas release.” Individuals can reduce their contribution by creating less waste at the start — for instance, buying reusable products and recycling.

In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive (动机) for reducing waste. If producers are required to take back packaging they use to sell their products, would they reduce the packaging in the first place?

Governments’ incentive to require producers to take responsibility for the packaging they produce is usually based on money. Why, they ask, should cities or towns be responsible for paying to deal with the bubble wrap (气泡垫) that encased your television?

From the governments’ point of view, a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.

1.By mentioning the Swiss study, the author intends to tell us that __________.

A. the weight of e-goods is rather small

B. natural minerals contain more precious metals

C. E-waste deserves to be made good use of

D. the percentage of precious metals is heavy in e-waste

2.The responsibility of e-waste treatment should be extended __________.

A. from producers to governments　　 B. from distributors to governments

C. from individuals to distributors　　 D. from governments to producers

3.What does the passage mainly talk about?

A. The increase in e-waste.　　 B. The management of e-waste.

C. The seriousness of e-waste.　　 D. The creation of e-waste.

Sharks have lived in the oceans for over 450 million years. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely.

Sharks range in size from the 0.1 meter long dwarf-dog shark to the 18-metre long whale shark — the world’s biggest fish. The whale shark, like two other large shark species — the basking shark and the megamouth shark — are harmless to people because they feed on plants and small aquatic animals.

Sharks have extremely sensitive sense organs. Some sharks can detect the scent(气味) of decaying fish or blood even when it is diluted(稀释) to only one part per million parts of seawater. They can probably hear underwater sounds that originate as far as 3 kilometers away and can tell the direction from which underwater sounds are coming.

Sharks are key predators(肉食动物) in the world’s oceans, helping control the numbers of many other ocean predators. Without sharks, the oceans would be overcrowded with dead and dying fish.

Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which makes a profit for the sellers. Other sharks are killed for sport and out of fear. Sharks are vulnerable to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring.

Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of sharks injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits.

If you are a typical ocean-goer, your chances of being killed by an unprovoked(无缘无故的) attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than by a shark.

Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.

Sharks are among the few animals in the world that almost never get cancer and eye cataracts. Understanding why can help us improve human health. Chemicals extracted from shark cartilage(软骨) have killed cancerous tumors in laboratory animals, and these chemicals may someday help prolong our life.

Sharks are needed in the world’s ocean ecosystems. Although they don’t need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.

1.Which statement best expresses the main idea of the article?

A. There are many different species of sharks, but only a few of them are dangerous to humans.

B. Sharks are important to the ocean ecosystem and they are a valuable resource for humans.

C. Although some sharks are dangerous to humans, they can help save human lives.

D. Sharks always eat small fishes and they are an essential part of the world’s oceans.

2.Which question is NOT answered in the article?

A. How long does a shark live?

B. How many people are killed by sharks each year?

C. Why are sharks important in medical research?

D. What do humans kill sharks for?

3.It can be inferred from the passage that ______________.

A. movies have given people the wrong impression of sharks

B. most sharks are dangerous to humans

C. sharks will attack anyone who is wearing black

D. it is very likely that ocean-goers will be killed by a shark

All over the world, and for many different reasons, there are millions of people who rarely or never eat meat. These people are called vegetarians. To people who eat meat, being a vegetarian may seem like a very strange thing, diets for several different reasons.

First, vegetarians have an enormous health advantage. One of the major health problems in modern societies is not too much protein but too much fat, especially in the form of animal fats. Medical evidence suggests that animal fats, including butter, contribute to the development of cholesterol in the human body. High amount of cholesterol seem to be part of the cause of heart disease. Most vegetarians have low level of cholesterol.

高二英语单项填空困难题查看答案及解析

Over millions of years， African penguins have developed a keen sense of where to find food． Once they're old enough， they set off from the shores on which they were hatched（孵化） for the first time and swim long distances in search of tasty fish like anchovies and sardines． But they don't search directly for the fish themselves． When African penguins head out to sea， they look for areas with low surface temperatures and high chlorophyll（叶绿素）． Because those conditions signal the presence of algae（藻类）． And lots of algae means lots of plankton（浮游动物）， which in turn means lots of their favorite fish． Well， that's what it used to mean．

Climate change plus overfishing have made the penguin feeding grounds a mirage（海市蜃楼）． The habitat is indeed plankton﹣rich， but now it's fish﹣poor． Researchers call this an "ecological trap．" "It's a situation where you have a signal that previously pointed an animal towards good﹣quality habitat． That habitat has been changed， usually by human pressures． The signal stays， but the quality in the environment gets worse．"

Richard Sherley， a zoologist at the University of Exeter and his team used satellite imaging to track the African penguins from eight sites along southern Africa． Historically， the birds benefited from tons of fish off the coasts of Angola， Namibia and western South Africa， but now they're going hungry．

"I was really hoping we'd see them going east， and finding areas which the fish had moved to but it ends up being quite a sad story for the penguins．" said Richard．

The researchers calculate that by falling into this ecological trap， African penguin populations on South Africa's Western Cape have declined by around 80 percent．

Some research groups are exploring the idea of moving them to a place where they can't get trapped， like the Eastern Cape． But Sherley thinks that a solution in the long run means making and carrying out rules to create more sustainable（可持续的） fishing industry， which needs public support．

1.How do penguins find their food？

A. They discover fish with their keen sense．

B. They swim long distances directly for fish．

C. They make signals to each other when finding fish．

D. They look for warmer and greener areas．

2.What is an ecological trap for the African penguins？

A. A trap set to catch penguins．

B. A good fish habitat with few fish．

C. A habitat rich in plankton．

D. A mirage on the sea．

3.What can be done to help the penguins in the long run？

A. Move the penguins to other places．

B. Create nature reserves for penguins．

C. Keep a balanced fishing industry．

D. Increase the population of penguins．

4.What is the main idea of the passage？

A. African penguins are losing their habitats．

B. African penguins are falling into ecological traps．

C. A sustainable development is needed．

D. African penguin populations have declined．

Boxing games are truly widely supported by a lot of people over the world . The sport involves two people fighting with each other inside a ring with a referee making sure that the fight goes on smoothly. The fighters have to be of the same weight to be able to fight and they make use of their fists according to the rules of competition.

There are three ways in winning the game. First, you have to knock out the challenger. Secondly, there is the technical knockout (击倒). This usually happens when the rival is seriously hurt and unable to carry on and defend himself. Thirdly, each boxer gets on with the fight until the last round is over and done with and the winner is judged according to the scores he gets.

The first boxing champion was James Figg who came from England. It was in 1719 that the word "boxing" was known. The sport then was completely different from what you are used to seeing and observing nowadays. In 1743 Jack Broughton, a boxing title holder, was responsible for coming up with the rules and regulations to make the fight more manageable.

Under these rules, a boxer who falls and does not fight after 30 seconds has elapsed is declared the loser and any fighter is prevented from hitting his opponent when he is already down. Broughton was also the one who created the mufflers -- a kind of gloves with padding which were used during presentations and training.

Today, the sport has a total of 12 rounds with three minutes playing time for each round. Boxers are given a minute for them to rest or for consultation with their respective coaches. A referee has the responsibility of making sure that the boxers carry on with the fight according to the rules of the sport. The judges have the task of evaluating each fighter and give the fighter scores according to their punches(拳法).

a. The boxer is prevented from hitting his opponent.

b. The boxer is unable to carry on and defend himself.

c. The boxer is given the highest scores by the judges.
