There are more species of beetles than any other form of life. About 380 000 species of beetles are known to exist, and more are discovered all the time. There are several theories about why there are so many beetles, but fossils evidence shows that beetle species die out less than other animals, Beetle species exist in such huge number because beetles are true survivors. They refuse to die out.

One of the reasons beetles survive so well is their body design. Most beetle species have two pairs of wings. The front pair of a beetle’s wings are hard and thick. They are not used for flying. These protect the back set of wings and the beetle’s stomach. Instead, some species of beetles have lost the ability to fly, but they are still equipped with front wings. The wings protect the beetle’s soft parts from harm. These features help protect beetles, which makes them less likely to die out if they are faced with new predators (捕食性动物).

Beetles can also eat a wide range of foods. Beetle species live all over the world, and they have many different types of food available to them. Most beetles are omnivores. That means they eat both plants and animals. Their mixed diets help beetles adapt to many different habitats. Over the course of time, food sources, like certain plants and animals, do not exist anymore. Others spring up. The beetle survives because it can find something to eat, no matter what.

Finally, beetles are good at moving quickly over long distance. Any change in an animal’s environment can be dangerous to it. For example, many species died out during the Ice Age, when Earth’s temperature dropped for a long time. However, some species can avoid dangerous environment changes by moving to a new place. Research shows that beetles respond quickly to shifts in temperature. They can move to safer environments.

Beetles’ bodies and habits help give them an edge over other creatures. They are unlikely to die out. As a result, beetles make up nearly one quarter of all animal species. There are more types of beetles on Earth than there are types of plants. Some types of beetles that exist today were around during the Permian period of history, 284 million years ago. Beetles, clearly, are here to stay.

1.What is important about a beetle’s front wings?

A.They are used to catch the prey.

B.They enable the beetle to fly.

C.They help the beetle move quickly.

D.They protect the soft body parts.

2.How do beetles respond to changes of habitats?

A.They are adaptable to the food change.

B.They can change their body temperature.

C.They are adaptable to the freezing cold weather.

D.They can use their wings to fight against the cold.

Is There Life on Earth?

There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20,000 light years ago).

Because of excellent weather conditions and extremely strong signals, Venusian

scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”

“How do you know this?” the science reporter of the Venus Evening Star asked.

“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe the air and survive.”

“What does this mean as far as our flying saucer program is concerned?”

“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”

“Are there any other dangers that you discovered in your studies?”

“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We call this the Consolidated Edison Belt. We don’t know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”

“Over here you will notice what seems to be a river, but the satellite findings indicate it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”

“Sir, what are all those tiny black spots on the photographs?”

“We are not certain. They seem to be metal particles(粒子) that move along certain paths. They emit gases, make noise and keep crashing into each other. There are so many of these paths and so many metal particles that it is impossible to land a flying saucer without its being smashed by one”.

“What are those stalagmite(石笋) projections sticking up?”

“They are some of granite formations that give off light at night. Prof. Glom has named them skyscrapers since they seem to be scraping the skies. ”

“If all you say is true, won’t this set back the flying saucer program several years?”

“Yes, but we shall continue as soon as the Grubstart gives us the added funds.”

Prof. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?

“Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere.”

1.According to Prof. Zog, the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because ________.

A. they need it on their way to the planet of earth

B. the earth’s atmosphere is filled with deadly gases

C. oxygen is far from enough in the area of Manhattan

D. there is no air on the planet of Earth

2.The “dark black cloud” in the 10th paragraph indicates ________.

A. the polluted air hovering over the surface of Earth

B. the mass of tiny drops of water floating above Earth

C. the mass of small things moving through the air

D. the dark clouds gathering before a storm breaks

3.The author wishes to call our attention to the fact that ________.

A. modern man has polluted his environment to such an extent that he may destroy himself if he carries on like this

B. there is no point in spending billions and billions of zilches to land a flying saucer on Earth

C. pollution has become so serious a problem on Earth that even Venusians find life there unbearable

D. it is difficult, if not altogether impossible, to land a manned flying saucer on Earth

4.The tone of this essay is ________.

A. hopeless and objective

B. serious and critical (批评的)

C. humorous and satirical (讽刺的)

The deep sea is one of the most mysterious places on earth. Scientists rarely go there. Those few do discover new species all of the time. Many places of the deepest parts of the ocean, where it's forever dark, can light up. Now, a teen's research has shown new light on how one of these swimming animals behaves in darkness.

The giant flashlight fish lives in the Indian Ocean as well as in tropical parts of the central and western Pacific. It lives at depths of up to 400 meters, (about 1,300 feet). But not always. Sometimes it lives in coral reefs in shallow waters. In those shallow waters, the blackish-blue fish comes out only at night. Reef-dwelling members of this species tend to be smaller than those living in deeper waters. Those biggies can grow to lengths of 35meters (14inches). That may not sound like a giant, but they are the largest of their type of fish.

The giant flashlight fish gets its name from a small glow-in-the-dark patch found in a packet of tissue under each eye, explains Caroline Edmonds. She is a 13- year-old student from Fountain Valley, Calif. There, she attends Talbert Middle School. She said that the eye pockets in these fish contain light-producing bacteria.

These bacteria and their host fish have built a relationship that helps both. The fish use the bacteria as a way to communicate with creatures around them. The bacteria gain nutrients from the fish and a safe place to live. When a fish wants to “ flash” its light, it turns the bacteria-filled pocket toward the outside of its body, Caroline explains. When a fish wants to hide its light, it turns the pocket back toward the inside. According to her data, the fish flash most often when they are being fed. They flash least often late at night, when they are resting.

1.The deep sea is dark and mysterious, but _________

A. a teen's research is going to light it up.

B. in the deepest part, lives a swimming animal.

C. scientists are looking for a new species to light up.

D. a kind of glowing fish has been found there.

A. It doesn't like living in warm places.

B. It can be found in coral reefs at times.

C. It doesn't like moving around at night.

D. It always lives at depths of up to 400 meters.

3.From where does the giant flashlight fish produce light?

A. Between its wings.

B. Inside its body.

C. Inside its back.

D. Near its eyes.

4.We can infer from the passage that Caroline Edmonds _________

A. is probably on a research team.

B. has learned about the fish in the library.

C. has always focused on her studies at school.

D. is one of the most famous American scientists.

5.What is implied in the last paragraph?

A. The light is usually on when the fish is excited.

B. The fish is sometimes troubled by the light.

C. The fish can decide when to “flash” its light.

D. The light is usually on when the fish is resting.

高二英语单项填空困难题查看答案及解析

In modern society there is a great deal of argument about competition. Some hold an optimistic attitude. They value it highly, believing that it is a natural outcome of social progress and prosperity（繁荣）and that anyone who wants to be outstanding has to keep the pace. Others think otherwise. They say that competition is bad; that it sets one person against another; that the unfriendly relationship between people because of competition.

I have taught many children who held the belief that their self-worth depended on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit（追求）of success, the development of many other human qualities is sadly forgotten.

However, while some seem to be lost in the desire to succeed, others have an opposite opinion. In a culture which values only the winner and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. They have no choice. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse: “I may have lost, but it doesn’t matter because I really didn’t try”. What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of the true competitors who try to prove themselves. Both are based on the mistaken belief that one’s self-respect relies on how well one performs compared with others. Both are afraid of not being valued. Only as this basic and often troublesome fear is overcome can discover a new meaning in competition.

1.What does this passage mainly talk about?

A. Competition helps to set up self-respect.

B. Opinions about competition are different among people.

C. Competition is harmful to personal quality development.

D. Failures are necessary experience in competition.

2.Why do some people favor competition according to the passage?

A. It pushes society forward.　　　　　　　　

B. It builds up a sense of duty.

C. It improves personal abilities.　　　　　　

D. It encourages individual efforts.

3.The underlined phrase “the most vocal” in Paragraph 3 means　　　　 .

A. those who try their best to win

B. those who value competition most highly

C. those who are against competition most strongly

D. those who rely on others most for success

4.What is the similar belief of the true competitors and those with a “desire to fail”?

A. One’s worth lies in his performance compared with others.

B. One’s success in competition needs great efforts.

C. One’s achievement is determined by his particular skills.

D. One’s success is based on how hard he has tried.

5.Which point of view may the author agree to?

A. Every effort should be paid back.

B. Competition should be encouraged.

C. Winning should be a life-and-death matter.

D. Fear of failure should be removed in competition.

高二英语单项填空中等难度题查看答案及解析

“Why should I care about the environment?” some people ask. There is a very simple reason: We live on the earth, and it is the only place we can live on right now, as we cannot live in space yet. If we treat the earth like a garbage dump, it will become dirty and unlivable. If we treat it well by being eco-conscious, the earth will stay clean and suitable for living, for ourselves and for our children.

What is “being eco-conscious”?

Being eco-conscious means being aware of your actions, and what you do to the environment. For example, you might think, “Using hairspray is great for fixing my hair.” However, if you are eco-conscious, you would ask, “Does this hairspray have CFCs in it? Could I be destroying the earth by using hairspray?”

How can I be eco-conscious?

You can find many simple ways to help the environment in your everyday life.

When you go shopping, bring a bag or a basket with you. Please try not to use plastic bags as much as you can.

You can go to work by bike or on foot if it is not far from your home.

You can put your rubbish into different bags, which makes it convenient for recycling.

You can eat less chewing gum.

You can use your own chopsticks instead of the disposable ones in your company or in restaurants.

You can put batteries in a special box instead of in garbage bins.

You can use the water which has been used for washing vegetables or fruits to clean the floor and the toilet or to water your garden.

You can turn off the decorative lights in your room when watching TV.

You can turn down your air conditioner by one degree, as this will cause a 10% reduction in energy use.

You can use recycled paper. Every ton of recycled office paper saves 380 gallons of oil. You can also use recycled glass instead of glass made from raw materials. This will reduce the related air pollution by 20%, and the related water pollution by 50%.

Please believe that. If you do a little, it will make a big difference.
