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

Article: Joke l: A man was sitting reading his papers when his wife hit him round the head with a frying pan. "What was that for?" the man asked. The wife replied, "That was for the piece of paper with the name Jenny on it I found in your pocket." The man then said, "When l was at the races last week Jenny was the name of the horse I bet on." The wife apologized and went on with the housework. Three days later the man was watching TV when his wife hit him on the head with an even bigger frying pan, knocking him unconscious. Upon regaining consciousness the man asked why she had hit again. Wife replied, "Your horse phoned." Joke 2: "Do you believe in life after death?" the boss asked one of his employees. "Yes, sir, " the new employee replied. "Well, then, that makes everything just fine, " the boss went on. "After you left early yesterday to go to your grandmother's funeral. she stopped in to see you!" Joke 3: "Oh, I am happy to see you, " the little boy said to his grandmother on his mother's side. "Now maybe daddy will do the trick he has been promising us. " The grandmother was curious. "What trick is that?" she asked. "I heard him tell mommy that he would climb the walls if you came to visit, " the little boy answered. Joke 4: A woman's husband had been slipping in and out of a coma for several months, yet she had stayed by his bedside every single day. One day, he signaled for her to come nearer. As she sat by him, he whispered, eyes full of tears, "You know what? You have been with me all through the bad times. When I got fired, you were there to support me. When my business failed, you were there. When I got shot, you were by my side. When we lost the house, you stayed right here. When my health started failing, you were still by my side... You know what Martha?" "What dear?" she gently asked, smiling as her heart began to fill with warmth. "I'm beginning to think you're bad luck..."

question:
Article: Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents. Instead, they have to search hard for information from dinosaurs' fossils because dinosaurs died out millions of years ago. It's very difficult for the scientists to reach an agreement because different results can be got from the same fossils. Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck all at once, or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone. Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. "That's pretty much settled at this point," says Paul Sereno. A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together. As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaurs-birds and crocodiles-for possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same. There is still a long way to go before the above questions could be answered. Dinosaur scientists, will have to find more proof to reach an agreement.
Question: Dinosaur scientists can get information directly by _ .
Options: (A) studying dinosaur fossils (B) examining modern animals (C) watching dinosaurs (D) using telescopes
Asnwer: D
answer:
No
