BEIJING, Feb. 26 (China Daily) -- As the smog orange warning continues, tourist attractions in Beijing are experiencing a significant decline (下降) in visitor number.

A new report launched by Beijing authorities on the morning of February 24 indicates that the concentration of PM 2.5 has risen, with no sign of decreasing, the orange warning will still be in effect, according to Xinhua News Agency.

According to data released by the Beijing Tourism Website, by 2:00 pm, February 24, popular tourist attractions including The Great Wall and Palace Museum had been affected by the smog in terms of tourist numbers.

As for the Palace Museum, the number of visitors was only 11,200 that day, far from the figure of 40,000, which is the daily average number of visitors it normally receives.

There were a few visitors in Beihai Park on the morning of February 24, and two visitors from Hebei province planned to end their morning tour earlier than scheduled because of the smog. One of them said, “The visibility is so poor that we can’t take good photos, or even see clearly. We’d better leave early.”

In response to worsening air conditions, travel agencies have also taken some measures to avoid a further decline in tourist numbers. An employee with China Youth Travel Service, Wang Tao, said the agency will inform tourists of the weather conditions at their destinations. A tour guide with China Travel Service also told the media that it was a tour guide’s duty to inform foreign visitors of the smog conditions in Beijing, and the agency will provide free face masks to those in need. But efforts to do so merely treat the symptom rather than the disease itself, because the root cause is air pollution. China will introduce various emergency responses and long-term measures against air pollution. Officials and experts called for combined efforts by governments, industries and the public to cooperate more efficiently and to jointly solve the problem.

1.In the following statements, which one is NOT TRUE?

B. Both the Great Wall and Palace Museum had been affected by the smog.

C. The concentration of PM 2.5 has risen, but it will decrease soon.

D. According to the data released by the Beijing Tourism Website, we can know the information.

2.According to the passage, if the weather is fine, how many visitors will the Palace Museum receive in a week?

A. About 11,200. B. About 78,400.

C. About 40,000. D. About 280,000.

3.The most effective way to solve the problem of air pollution is to _______.

A. take some measures of treating the symptom merely

B. unite the power of governments, industries and the public

C. provide free face masks to those in need

D. inform tourists of the weather conditions at their destinations

4.What does the author most probably mean by saying “efforts to do so merely treat the

symptom rather than the disease itself” in the last paragraph?

A. These efforts could treat the symptom and the disease.

B. Treating the symptom is more important than the disease.

C. These efforts are not enough to solve the problem thoroughly.

D. These efforts couldn’t treat the disease, so they are unnecessary.

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 Coral bots—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 coral bots 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

Cambridge graduates are the most employable in the world，according to a global league table．The ancient university is the best at producing graduates who are‘ready to work’，a poll of major employers found．

Oxford slipped to fourth place in the rankings having taken top spot last year．Harvard and Yale—part of the US‘Ivy League’of universities—were second and third respectively．

Five British universities were ranked in the top 20—one more than last year—and 12 were in the full list of 150．

But the UK as a country came third—behind the US and Germany—when companies were asked to name the best nation for producing work—ready graduates．

The table—the Global Employability(就業(yè)能力)University Ranking published by the International New York Times—also showed that universities in Asian countries were rapidly gaining ground on their western counterparts (對手)．

Asian universities claimed 20 percent of the top 150 places in 2014 compared with only 10 percent when the tables were first published in 2010．

The other British universities in the top 20 were University College London，in 14th place，Imperial College London，in 15th，and Edinburgh，18th．

The table showed the gap between a small number of top UK universities and less famous institutions．

Laurent Dupasquier，managing partner at Emerging，a French human resources consultancy，said：“The top tier players．global brands (which tend to be all American and British)．continue to lead，while other Anglo—Saxon universities，those that are mainly regional players，tend to develop less well，with an average of five places lost in comparison with last year．”

“Like the Premier League(英超聯(lián)賽)，the champions have an international community of students and think internationally，unlike their more locally oriented counterparts．”

The table was made following a survey of 2,500 major companies in 20 countries．Employers were asked to rank universities against a range of criteria including their production of graduates who are ready to work and their links with business．

The study claimed that‘the days of ivory towers are over’．

1.Which university had the best work-ready graduates last year?

A．Cambridge． B．Oxford． C．Harvard． D．Yale．

2.The underlined phrase“gaining ground”in Paragraph 5 probably refers to ____________．

A．falling behind

B．coming into conflict

C．making room

D．becoming more successful

3.What can we learn about the UK universities from the text?

A．There are many quality gaps between UK universities．

B．The UK produced the most work-ready graduates this year．

C．Universities in the UK make up most of the top 20．

D．Almost all UK university graduates are employable．

4.Why do regional UK universities tend to develop less well this year?

A．They couldn’t raise enough education fund．

B．They have students from all over the world．

C．They lack international students and think locally．

D．The UK government didn’t support them at a11．
