Question: Article: Coral reefs 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 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 the function of reefs.It is in the final stage of testing.Once ready, the researchers hope to build hundreds of _ and use them effectively in the waters off Scotland and then hopefully in the oceans across the world."
Question: Which of the following is a cause of the danger that coral reefs are facing?
Options: (A) The appearance of new creatures. (B) The seriously polluted sea water. (C) The activities of volunteer divers. (D) Human activities like bottom operation.
Asnwer: D

Answer: Yes

Question: Article: You can have your adventure and eat too at Europe's first green restaurant where traditional German food is served in a beautifully lit wooden hilltop restaurant powered by solar energy at a height of 1,025 metres among tall trees in the Black Forest. The Rappenecker Hutte is a 350-year-old farm house in south Germany which has been serving as a hikers' restaurant for several years. It was the starting point of the downhill course of the Mountain Bike World Championship (MBWC) in 1995 and is a well-known station of the Black Forest Ultra Bike Marathon (BFUBM). "People come here for adventure trips, mountain biking or hiking and stop for traditional German food. We produce all our energy from renewable sources as it is very expensive to get a power grid connection at this site," said Dirk Behringer, owner of the Rappenecker Hutte. Like the restaurant, the story of its present owner is equally amazing as Behringer, 57, left his well-paid job in 2003 to stay here with his wife. "I have traveled across the world and as I was growing old I realized I wanted to retire and live in nature. So I rented the restaurant. Since then I, along with my wife, live here in summer and we travel during winter," said the six-foot-tall man dressed in a T-shirt and shorts. Due to heavy snow during winter, the restaurant opens only for six months from April to September when it receives around 500 guests per week. The Behringer couple has employed no helper and does everything from cooking to cleaning at this hilltop restaurant which gives a picturesque view of the Black Forest. There are not many dishes on the menu for unexpected visitors. On a routine basis, there is one vegetarian dish which includes fried potatoes with dense milk cream, boiled vegetables and fresh salad. The non-vegetarian dish includes fried potatoes with pork and salad. There are also options to pick from fresh juices, hard drinks and coffee. All vegetables, fruits, dairy products and meat supplies to the restaurant come from farms in nearby villages.
Question: By mentioning such events as MBWC and BFUBM, the author intends to _ .
Options: (A) prove the restaurant has a long history (B) advise us to do more exercise (C) stress the restaurant's being unusual (D) express his fondness of the restaurant
Asnwer: C

Answer: Yes

Question: Article: A new study has been carried to test the role of story telling in lowering blood pressure. Dr. Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that investigated how pre-recorded videos of hypertension patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months. Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine. They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier. Hypertension is difficult to control, since it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies have been ly ineffective because people find it hard to follow those medical requirements. In the test, his team carefully chose their story-tellers from 230 members of a patients' community with whom they could most easily relate. Next, they divided their study population into two groups. One received three interactive DVDs containing the tellers' stories of their experiences in living with and treating their hypertension. The other were given educational discs on an unrelated health topic. The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure. While the study did not _ how the story-telling influenced the patients' behavior, Houston suspects that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension. They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect.
Question: We can learn from the text that the pre-recorded videos _ .
Options: (A) tell medical histories of hypertension patients (B) introduce some medical treatments of hypertension (C) introduce a good lifestyle for hypertensive patients (D) tell scientific discoveries of the scientist group
Asnwer: C

Answer:
No
