Coral reefs(珊瑚礁) are not just beautiful to look at,but also very useful.They shelter nearly 25% of ocean life and provide food for billions of people.However, like many other species,this amazing ecosystem(生態(tài)系統(tǒng)) is in danger of dying out!

There are two main reasons for the destruction—the rising carbon dioxide levels caused by global warming as well as human influences like bottom operation.While not much can be done about the former,the loss caused by the latter can be reduced.

Bottom operation involves dropping nets to the ocean bed and then dragging them up when filled with fish.This action damaged the ocean floor,causing the coral branches to separate from the reefs.While that is very discouraging,the good news is that if these branches are found quickly,they can be saved.At present,that work is being performed by volunteer divers. But the method has only limited success because they cannot stay long underwater, nor reach depths of over 200 meters where some of the deep-sea coral grows.

However,this is not the case for Coralbots—the robots that can constantly seek out broken branches.A team of ‘coral bots’,each individually working to simple rules will piece together damaged bits of coral, allowing them to regrow. They are programmed to be able to distinguish between other things and the coral.The robots work together in groups,similar to bees.If one coralbot is damaged, then the others will still be able to complete the task.

Dr Lea-Anne Henry said:“The project of using coralbots offers us the possibility to restore(修復(fù)) the function of reefs.It is in the final stage of testing.Once ready, the researchers hope to build hundreds of them and use them effectively in the waters off Scotland and then hopefully in the oceans across the world.”

1.Which of the following is a cause of the danger that coral reefs are facing?

A.The appearance of new creatures.

B.The seriously polluted sea water.

C.The activities of volunteer divers.

D.Human activities like bottom operation.

2.Compared with volunteer divers,coralbots ________.

A.can stay longer underwater

B.must work as bees do

C.can distinguish what is coral

D.can never be damaged

3.What does the underlined word“them”in the last paragraph refer to?

A.Coralbots.B.Broken branches.

C.working bees.D.Bits of coral.

4.We can infer from the passage that ________.

A.bottom operation has affected most underwater creatures

B.broken branches of coral can regrow if saved in time

C.hundreds of the coralbots have worked well in the oceans

D.with the coralbots all damaged coral reefs can be restored

The kindly “Chinese Fortune Grandpa” wearing Han Chinese clothing and holding a fortune bag debuted (亮相) at the Imperial Ancestral Shrine in Beijing on the day after Christmas. The final image of the Chinese gift-giver was selected through a global design competition against “Santa Claus”, according to a report by Guangming Daily.

Many Chinese cities have been filled with Christmas neon lights, Christmas songs, Christmas trees, and the images of “Santa Claus”in recent days. As a matter of fact, foreign festivals are becoming more popular than certain traditional Chinese festivals among the Chinese people, particularly the youth. “Certain traditional festivals have died out because people have forgotten their spiritual meanings, ”said noted writer Feng Jicai. More and more Chinese people are beginning to exchange gifts on Valentine's Day and Christmas. However, many of them know nothing about Chinese New Year pictures or sugarcoated figurines(小糖人), and have never heard suona music. Certain folk customs on the Dragon Boat Festival, Tomb Sweeping Day, and other traditional festivals have gradually disappeared. Under such circumstances, even the “Chinese Fortune Grandpa” is unlikely to defeat “Santa Claus”.

However, it is not a bad thing to some extent. It constantly reminds people to restore the “true face” of traditional festivals. China has listed traditional Tomb Sweeping Day, Dragon Boat Festival and Mid-Autumn Festival as legal holidays, which brings more paid leaves to the public, and helps to awake the public awareness of traditional festivals.

In modern society, festival is a carrier of culture and its meaning largely depends on their understandings and usages by people. Compared with foreign festivals, traditional Chinese festivals are not inferior (次于) in cultural meanings, but lack of fashion sought by modern people. If people do not appreciate the historical culture contained by traditional festivals, and only take pleasure-seeking as the most important, the significance of traditional festivals will fade away and the inheritance (繼承) of fine traditional culture will be cut off.

1.The second paragraph implies that ________.

A. traditional festivals should co-exist with foreign festivals

B. all the Chinese festivals are disappearing in the near future

C. western festivals are constantly impacting on our festivals

D. the Chinese people have the public awareness of traditional festivals

2.We can learn from the passage that ________.

A. an image designed by the Chinese people will be displayed

B. the Chinese gift-giver was intended to symbolize traditional culture

C. many foreigners know nothing about Chinese festivals

D. the Chinese are beginning to exchange gifts on the Mid-Autumn Festival

3.Many Chinese youth dislike traditional festivals because they think ________.

A. traditional festivals are out of fashion now

B. the historical culture is more difficult to understand

C. western festivals contain more cultural meanings

D. the inheritance will cut off their contact with western festivals

4.What would be the best title of the passage?

A. Gone are Chinese Traditional Festivals

B. True Face of Chinese Traditional Culture

C. Foreign Festivals Popular with Chinese

D. Chinese Fortune Grandpa VS. Santa Claus

Freshmen anywhere may be nervous about university life.Here, three pieces of advice are for them.

Listen but don't be silent

The world is held in students’ hand via smart phones. Thus, they may consider lecture listening less important. 1. It forces students to face the difficulties of training a deep attentiveness. Unsurprisingly, students find it hard to speak out, ask questions or for points of clarification. They don't want to appear foolish or incapable. However, there is no such thing as a foolish question. Teachers are there to help you understand. This also goes for seminars and workshops. 2.

Read and buy books

3. There're so many useful online sources today, but the habit of reading books, especially whole books, is something being lost. Buy your own books.There are many bargains to be found on used-book websites or through Amazon. Being a book lover and buyer will help any student get the most out of their education.

4.

As a student, you don't just have to learn to listen and become an active reader: you also have to become an academic writer. Written work at college level cannot be done at the last minute or in a rush. It takes time. Turn to your teachers. If they will read draft essays then make sure you can get feedback(反饋) ahead of the final submission. 5.

Students who get feedback on their work always do better than those who do not. It is one of the few educational laws that holds true in all cases.

A. Don't try to do it all the night before.

B. However, a lecture is a listening workout.

C. Thinking clearly cannot be done in a rush.

D. So train your ear, listen carefully, but don't be silent.

E. Reading is the most important thing that any student does.

F. Re-writing has proved to be the turning point in one's degree.

G. If they won't read drafts, then see them to run through your ideas.

科目:高中英語 來源:2017屆甘肅民樂縣一中高三10月考英語試卷(解析版) 題型:閱讀理解

If you have a chance to go to Finland, you will probably be surprised to find how “foolish” the Finnish people are.

Take the taxi drivers for example. Taxis in Finland are mostly high-class Benz with a fare of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to(料理), and then walk off without paying your fare. The driver would not show the least sign of anxiety.

The dining rooms in all big hotels not only serve their guests, but also serve outside diners. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals. The most they would do to show their good faith is to wave their registration card(住宿登記卡) to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends to dine free of charge.

The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed with the boss on the rate(價(jià)錢). From then on, they just say how many hours they have worked and they will be paid accordingly(相應(yīng)地).

With so many loopholes(漏洞) in everyday life, surely Finland must be a heaven to those who love to take “petty advantages”. But the strange thing is, all the taxi passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. And workers always give an honest account of the exact hours they put in. As the Finns always act on good faith in everything they do, living in such a society has turned everyone into a real “gentleman”.

In a society of such high moral practice, what need is there for people to be on guard against others?

1.While taking a taxi in Finland, ________.

A. a passenger can go anywhere without having to pay the driver

B. a passenger pays two US dollars for a taxi ride

C. a passenger can never be refused by the taxi driver wherever he wants to go

D. a passenger needs to provide good faith demonstration (證明) before leaving without paying

2.We know from the passage that big hotels in Finland ________.

A. are mostly poorly managed

B. provide meals for any diners

C. provide free wine and charge for food

D. provide meal for only those who live in the hotels

3.Which of the following is NOT true according to the passage?

A. The workers in Finland are paid by the hour.

B. The workers are always honest with their working hours.

C. The workers and their bosses will make an agreement in advance about the pay.

D. The bosses in Finland are too busy to check the working hours of their employees.

4.The word “those” in the last but one paragraph probably refers to ________.

A. people who are dishonest

B. people who often have meals in big hotels

C. people who often take taxis

D. people who are worthy of trust
