1970 was “World Conservation Year”. The United Nations wanted everyone to know that the world was in danger. They hoped that the governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1300 different plants, trees and flowers in Holland, but now only 860 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and the water, and everything that grows and lives. We can't live without these things. If we continue like this, we shall destroy ourselves.?

What will happen in the future? Perhaps it is more important to ask “What must we do now?” The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are hoping to save our world. They plant trees, build bridges across rivers in forests and so on. In a small town in the United States a large group of girls cleaned the banks of eleven kilometres of their river. Young people may hear about conservation through a record called “No, One's Going to Change our World. ” It was made by Scatles, Cliff Richard and other singers.

科目:高中英语 来源:2013届湖南省望城一中、长沙县实验中学高三10月联考英语试卷(带解析) 题型:填空题

Write NO MORE THAN THREE WORDS for each answer.
Why must we pay taxes(税收)? The answer is that the government needs money for many things, for example, to pay its soldiers, sailors and airmen, to build roads, bridges, offices, schools, etc, and to buy goods from abroad; and only the people of the country can supply the money.
One of the most important taxes is income-tax which a person pays according to the amount of his income, whether he is a merchant, a doctor, a lawyer, a shopkeeper, a miner or anything else. This is called a “direct” tax, because it is paid in money directly to the government.
Another tax is paid on goods such as watches, jewelry, new clothes, tobacco, wine, etc, when they are brought into a country. Such a tax is paid as part of the price of these goods if they are late sold in shops. We call it “indirect” tax, because it is paid indirectly through the shopkeepers.
People usually complain about having to pay taxes, but they forget that the money is spent on things that they and their families need. We need policemen to catch thieves, to see that men obey the laws, to direct traffic, etc, and they must be paid what they earn; children need education and there must be schools and teachers; we want our streets to be kept clean, and the wages of men who do this kind of work have to be paid. Above all, the country must always be ready to defend itself against attacking enemies, and we can’t have an army without paying for it. Besides, if a country wants to develop, there are many other things to do.
Taxes, therefore, cannot be avoided. We buy our food and clothes and pay for our amusements; but, there are several things that the State finds the money for, and that is necessary for us if our society is to continue. We have no real reason to complain, therefore, when we are asked to supply money to be spent for the good of ourselves and for our fellow-citizens.

There is a famous story about British poet Samuel Taylor Coleridge. He was writing a poem when he was interrupted by a knock at the door.

This was an age before telephones. Someone was delivering a message. When Coleridge got back to his poem, he had lost his inspiration. His poetic mood had been broken by the knock on his door. His unfinished poem, which could otherwise have been a masterpiece, would now never be more than a fragment.

This story tells how unexpected communication can destroy an important thought, which bring us to the cellphone.

The most common complaint about cellphones is that people talk on them to the annoyance of people around them. But more damaging may be the cellphone’s interruption of our thoughts.

We have already entered a golden age of little white lies about our cellphones, and this is by and large(大体上)a healthy, protective development. “I didn’t hear it ring” or “I didn’t realize my phone had shut off” are among the lies we tell to give ourselves space where we’re beyond reach.

The notion of being unreachable is not a new concept—we have “Do Not Disturb” sign on the doors of hotel rooms. So why must we feel guilty when it comes to cellphones? Why must we apologize if we decide to shut off the phone for a while?

Now time alone, or a conversation with someone next to us which cannot be interrupted by a phone, is something to be cherished. Even cellphone devotees(信徒), myself usually included, can’t help at times wanting to throw their phone away, or curse the day they were invented.

But we don’t and won’t, and there really is no need. All that’s required to take back our private time is a general social recognition that we have the right to it. In other words, we have to develop a healthy contempt for the rings of our own phones.

A cellphone call deserves no greater priority than a random word from the person next to us,though the call on my cellphone may be the one-in-a-million from Steven Spielberg—who has finally read my novel and wants to make it his next movie. But most likely it is not, and I’m better off thinking about the idea I just had for a new story, or the slice of pizza I’ll eat for lunch.

1.What is the point of the anecdote(轶事)about the poet Coleridge in the first three paragraphs?

A.To direct readers’ attention to the main topic.

B.To show how important inspiration is to a poet.

C.To emphasize the disadvantage of not having a cellphone.

D.To encourage readers to read the works of this poet.

2.What does the writer think about people telling “white lies” about their cellphones?

A.It is a way of signaling that you don’t like the caller.

B.It is natural to tell lies about small things

C.It is basically a good way to protect one’s privacy.

D.We should feel guilty when we can’t tell the truth.

3.According to the author, what is the most annoying problem caused by cellphones?

A.People get so obsessed (着迷) with the cellphone rings that they fail to notice anything else.

B.People feel guilty when they are not able to answer their cellphones.

C.Cellphones interrupt people’s private time.

D.With cellphones it is no longer possible to be unreachable.

4.What does the last paragraph suggest?

A.A person who calls us from afar deserves more of our attention.

B.Steven Spielberg once called the author to talk about the author’s novel.

C.You should always finish your lunch before you answer a call on the cellphone.

D.Never let cellphones disturb your life too much.
