There are three separate sources of danger in supplying energy by nuclear power．

First, the radioactive (有放射性的) material must travel from its place of production to the power station． Although the power stations themselves are strongly built, the containers used for the transport of the materials are not． Normally, only two methods of transport are in use, namely road or rail． Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas．

Second, there is the problem of waste． All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years． It is impossible to make these wastes non-radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented． For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea． However, these methods do not solve the problem, since an earthquake could easily break the containers．

Third, there may occur　 the danger of a leak (泄漏) or an explosion at the power station． As with the other two dangers, this is not very likely, so it does not provide a serious objection (不赞成，反对) to the nuclear program． However, it can happen．

Separately, these three types of dangers are not a great cause for worry． Taken together, though, the probability of disaster is extremely high．

1.Which of the following is not true?

A．It is likely that a leak or an explosion occurs at a power station．

B．It is not usual for radioactive materials to be conveyed across land．

C．The containers are likely to be broken by an earthquake．

D．Nuclear wastes remain risky in most cases for many years．

2.The author thinks that the ways to store nuclear wastes are　 __________．

A．easy　　　　　　　　　　 B．impossible

C．reasonable　　　　　　 D．ineffective

3.What do we learn from the last paragraph?

A．The power station is a place that frees from danger．

B．The dangers of nuclear energy could be prevented．

C．The general public are opposed to the nuclear program．

D．By itself, none of the three dangers is very likely to lead to much worry．

4.What is this passage about?

A．Uses of nuclear power．

B．Dangers from nuclear power．

C．Public anger at nuclear power．

D．Accidents caused by nuclear power．

There are three separate sources of danger in supplying energy by nuclear power.

First, the radioactive material must travel from its form of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even though, heavily populated areas.

Secondly, there is the problem of waste. All nuclear power stations produce waste that in most cases will remain radioactive for thousands of years. It is impossible to make these waste radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.

Third, there may occur the danger of a leak or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.

Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high.

There are about 6，500 languages spoken throughout the world，but about half of them are in danger of disappearing.

One of the primary causes driving language loss is that support for language communities drastically varies.While some languages are recognized by governments and taught in schools，the majority go unrecognized，unsupported，and untaught，leaving communities ill-equipped to pass their languages on to future generations.Tsakonian，a“dialect(方言)”in Greece，has declined to the point that only 100 speakers remain.

When a language disappears，many other things can go away as well.For example，parts of a community’s culture，knowledge and identity can also be lost.

One organization seeking to save world languages is Wikitongues，which was founded as a school project by Daniel Bogre Udell in 2012，when he began recording short oral histories in New York to explore the city’s rich cultural diversity with the simple idea:tell me about yourself or your home in your native language.When he posted the videos online，the channel quickly got wide attention.

There are currently over 400 languages and dialects represented on Wikitongues’channel and more than 1，500 people from 70 different countries have added videos to it.But that’s far from enough.The organization seeks to serve as an Internet resource to keep as many languages as possible alive.Udell believes they can make it happen.“There are many examples of languages that disappeared but later returned to use.Hebrew went extinct in the 4th century BC，and was revived(恢复)in the 1800s.Now once again，it's the mother tongue of half of the world’s Jewish population，”said Udell.

1.What can be inferred about Tsakonian in Greece?

A. It’s hard to speak and understand.

B. It will definitely die out in the future.

C. It’s not allowed to speak in Greece.

D. It lacks recognition and support.

2.What effect may be brought by the extinction of languages?

A. Harming future generations. B. Reducing cultural diversity.

C. Preventing daily communication. D. Changing school projects.

3.What’s the purpose of Wikitongues?

A. To support people in saving their languages.

B. To revive languages that have disappeared.

C. To record enough short oral histories.

D. To explore the world’s rich cultures.

4.What does Udell want to tell us by giving Hebrew as an example in the last paragraph?

A. All extinct languages will be brought back to life.

B. It’s possible to prevent languages from dying out.

C. More languages will be presented on Wikitongues’channel.

D. Hebrew has become one of the most popular languages in the world.

高三英语单项填空简单题查看答案及解析

There are around 6,000 living languages in the world—and at least half of these are in danger. In every part of the world, languages are disappearing. In fact, one scientist has said that languages are in more danger of extinction than birds or animals. Professor Steve Sutherland of the University of East Anglia says that in the past 500 years 4.5 percent of languages have died out—compared with 1.3 percent of birds, and 1.9 percent of mammals.

Languages come and go, and thousands have done exactly that without leaving any trace(痕迹). Only a very few—Basque, Greek and Latin among them—have lasted more than 2000 years. But it seems that the pace of their disappearance is becoming quicker.

The Ethnologue, a database of all the languages spoken in the world, states that 417 languages are spoken by so few people that they are in the final stages of becoming extinct. If very few people speak a language, it will probably die out.

Languages may be lost through migration, as people move from small towns to city centers, or when environments are destroyed by the search for oil or wood. Natural disasters can also devastate populations, and along with them, their language. Governments also play a role in the extinction of languages. The need to establish “official languages”, for a country to educate its children and carry out its business, had a disastrous effect on many small languages.

What is lost if a language is lost? Some people argue that languages die as the human race develops. Obviously there could be great benefits if everyone in the world spoke the same language—some industries already reflect this, with English essential for pilots and air traffic controllers. But there are more important things than convenience. As languages are lost, whole ways of life and knowledge may be lost along with them.

To put it simply, language expresses something about who we are, about where we live in the world. Ani Rauhihi, a Maori teacher in New Zealand’s North Island, sums it up: “If you grow up speaking our language, you won’t know who you are.”

1.What do the figures mentioned in the first paragraph suggest?

A. Most languages have died out completely.

B. Languages are in great danger of extinction.

C. Languages are disappearing slower than before.

D. Animals are disappearing faster than languages.

2.What can best replace the underlined word “devastate” ?

A. raise

B. control

C. improve

D. destroy

3.What if a language is lost according to the passage?

A. There will be great trouble.

B. There is no need to worry about it.

C. Its culture and knowledge will also be lost.

D. People will be able to communicate with others conveniently.

4.What can we infer from the last paragraph?

A. Languages reflect our identity.

B. People will speak the same language one day.

C. Ani Rauhihi cares less about languages dying out.

D. Fewer people will remember their own languages.

Though there are about 400 languages from all over the world that are in danger of disappearing completely, Zoque-Ayapaneco, a native Mexican language is considered the most likely to become extinct, because the only two people in the world that speak it fluently do not talk to each other!

And, it's not because they live in different countries, states or even villages. In fact, Manuel Segovia and Isidro Velazquez, both in their 70s, live within 500 yards of each other, in the village of Ayapa in the Southern Mexican State of Tabasco. They, however, refuse to communicate because they simply don't have much in common. Segovia is apparently a little flank in nature while Velazquez is described as shy.

Segovia was at least able to talk in Zoque-Ayapanece with his brother until he passed away about 12 years ago, and still manages to practice it with his family, especially his son Manuel, who for the last five years has been trying to learn it and hopes to become fluent enough to teach it to the next generation. Velazquez on the other hand, has not been heard speaking in the language with anybody.

The two men say the language used to be widely spoken in the village, but the younger generation shunned it for fear of being laughed at, and it therefore began to die a slow death, as the elders passed away.

Unless the two men get their acts together, the only way to hear the language will be to either listen to Manuel's not-so-fluent statement or see them talk in a documentary entitled “Lengua Muerta” (Dead Language) that is being filmed to capture Zoque Ayapaneco and 364 other native Mexican languages that are in a similar state.

We sure hope Segovia and Velazquez soon find something common to talk about. Maybe the fact is that the language is dying and that they should start encouraging and teaching the next generation together.

1.The reason why Segovia and Velazquez don't talk to each other is that ________.

A. they both are too shy

B. they live in different villages

C. they are too familiar to talk

D. they have no similarity in their character

2.What do we know about Zoque-Ayapaneco?

A. It was widely used twelve years ago.

B. It will be dying out if no effective measures are taken.

C. It will be popular in Mexico in the near future.

D. It is a Southern American language.

3.The underlined word “shunned” in Paragraph 4 probably means “________”.

A. favored                                B. identified

C. were unwilling to learn                D. protected

4.From the passage, we can conclude that ________.

A. altogether 365 languages are becoming extinct in the world

B. Segovia and Velazquez will communicate with each other soon

C. the government cares a lot about the protection of Zoque-Ayapaneco

D. we can hear the language from Manuel or documentary “Lengua Muerta”

5.What's the main idea of the passage?

A. World's endangered languages are being filmed.

B. Villagers are trying to protect their old language.

C. An endangered language is spoken by only two people.

D. There are a lot of languages in Mexico.

高三英语阅读理解中等难度题查看答案及解析

There are two dangers to be guarded against in old age. One of these is undue absorption in the past. It does not do to live in memories, in regrets for the good old days, or in sadness about friends who are dead. One’s thoughts must be directed to the future and to things about which there is something to be done.

It is unwise to be too attached to the youth in the hope of sucking vigor from its vitality. When your children are grown up they want to live their own lives, and if you continue to be as interested in them as you were when they were young, you are likely to become a burden to them, unless they are cold to you.

I think that a successful old age is easiest for those who have strong impersonal interests involving appropriate activities. It is in this sphere that long experience is really fruitful, and it is in this sphere that the wisdom born of experience can be exercised without being oppressive. It is no use telling grown-up children not to make mistakes, both because they will not believe you, and because mistakes are an essential part of education. But if you are one of those who are incapable of impersonal interests, you may find that your life will be empty unless you concern yourself with you children and grandchildren. In that case you must realize that while you can still render them material services, such as making them an allowance or knitting them jumpers, you must not expect that they will enjoy your company.

Some old people are afraid of death. But in fact the best way is to make your interests gradually wider and ore impersonal. An individual human existence should be like a river-small at fist, rushing passionately past rocks and over waterfalls. Gradually the river grows wider and the banks move back and in the end they become mixed in the sea without any visible break.

The old man who can see life in this way will not suffer from the fear of growing old and death.

1.The author suggests that old people should_______.

A. develop impersonal interests with proper activities.

B. tell their children not to make mistakes

C. concern themselves with their children

D. not give their children an allowance

2.The underlined word “render” in Paragraph 3 is close to the meaning of  “_____”.

A. return            B. reward           C. offer               D. demand

3.The author compares an individual human existence to a river because _____.

A. Life is like a river, first small, and then it becomes wide

B. life is like a river finally flowing into the sea

C. old age and death are both natural just like a river

D. old people will be mixed in the crowd like a river mixed in the sea

4.What’s the best title of this passage?

A. Setting Sun Is Beautiful           B. Growing Old Successfully

C. Why Fear Getting Old             D. Caring for Olds More
