Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood. Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear. This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert. Which title best fits the passage? A) Trees and Man B) The Function of Tree Wood C) How do People do with Trees? D) The Usage of Tree Roots

Have you ever noticed someone "talking" to them-selves? What did you think? The word "crazy" probably came to your mind. Wait a minute, though. Maybe they're doing something meaningful. Speaking practice can be effective in many different forms when people learn English or another foreign language. Imitating the speech of others is proven to be highly effective in developing a native speaker's level of fluency in a language. Actually you've already proven that to your-self. How? That's how you learned your first language! Whether it was English, Spanish, French or some other language, you "imitated" your mother, father, other family members, friends, teachers and whoever else was around making "talking" noises at you as you formed your first communicative language skills. So don't think those who are talking to themselves are "crazy". At least don't do so until you've tried it for your-self, in English or in your new foreign language. As you go through your day, in English or your new foreign language, tell yourself what you're doing at the moment and what you're going to do during the day. "Which of these shirts, ties, etc. should I wear today? Not this one, I wore it just last week. Maybe this one, but I don't like this color with the pants. Let's try another one," you might say as you are getting dressed. If you live alone, you can talk aloud whenever you want without disturbing others. If you don't live alone, however, then first explain to your family or roommates what you'll be doing, to avoid a quiet phone call to the local psychiatrist . From the passage we can know that _ . A) people who talk to themselves are crazy B) if you live alone, you should talk to yourself C) you should tell yourself what you're doing D) we learned our native language by imitating

Q: You have probably been told by your high school instructor that writing is an important and practical skill. However, you may not be convinced that the ability to write will be important in your own future. If so, you will be surprised at the results of a recent survey by the National Institute of Education. More than four thousand working men and women who had graduated fifteen years earlier were asked to name the courses they would have taken in college if they had known better. The designer of the survey expected people to name courses in computer science, mathematics, or business. But the course most often mentioned was writing. If you already have a job, you are probably not surprised at their answers. Many jobs require the ability to write. Despite the increasing use of the telephone and the computer, much information must be communicated in writing.Some ten million people--managers, engineers, sales representatives, and many others-- write regularly as part of their jobs. Summaries, reports, reports, letters and speeches are required in today's work world. The ability to write, therefore, is an important skill. The successful individual is almost always the one who can communicate successfully in writing. Writing communicates your thoughts and feelings to others; it also tells you something about yourself. Maybe this is what Eldridge Cleaver had in mind in his autobiography, "I started to write... to save myself...I had to seek out the truth... I had to find out who I am and what I want to be ,what type of man I should be ,and what I could do to become the best of which I was capable." The survey conducted by the National Institute of Education shows that. A) more than 4,000 working people value the course of writing B) many people regard computer science as a useful course C) some people would study business if they had a chance D) most people consider writing to be an important course

Question: Why do men die earlier than women? The latest research shows that the reason could be that men's hearts go into rapid decline when they reach middle age. The largest study of the effects of aging on the heart has found that women's longevity may be linked to the fact that their hearts do not lose their pumping power with age. "We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age," "Within the heart there are millions of cells that enable it to beat. Between the ages of 20 and 70 , one-third of those cells die and are not replaced in men," . What surprises scientists is that the female heart sees very little loss of these cells. "This gender difference might just explain why women live longer than men," said Goldspink. The team has yet to find why aging takes a greater toll on the male heart, said Goldspink.. The good news is that men can improve the health of their heart with regular exercise. The passage mainly talks about _ . A) men's heart cells B) women's ageing process C) the gender difference D) hearts and long life
Answer: D
Q: Germany's mystery English-speaking "forest boy" is said to be having trouble adjusting to conventional life. Source close to the case claim he is having difficulty sleeping in a proper bed and wants to return to the wild. Other creature comforts , such as soap, hot showers, and running water, are also " unsettling" the youngster.

He handed himself into officials on September 5, and was carrying a rucksack ,tent and sleeping bag. He told police his father had recently died after a fall and he had buried him in a shallow grave. He then walked north for a fortnight for help until he got to the German capital. Despite the bizarre nature of the story, police have said it is credible. The source said it was " unsurprising" the teenager found a soft bed so unusual if he had been sleeping rough for so long. "He has indicated that he would be far more comfortable on the forest floor and would prefer to return there to sleep," the source added. The boy claimed that his father had taken him into the woods south of Berlin after his mother, Doreen, died in a car crash. Now detectives have begun a search for the grave, or any other place where Ryan's body might be lying.

In the meantime, they are trying to make Ray a ward of court, so that an official can be appointed to make important decisions on his behalf. DNA, fingerprint and dental records can also then be handed to Interpol so that his records can be checked against those of missing children. A police spokesman confirmed that a search had started for Ryan's grave after the boy said that he was buried under the stones " two weeks south of Berlin". Police are puzzled by the case, but say that everything Ray has told them so far adds up. Officials believe the teenager could be... Which of the following statements about " forest boy" is TRUE?
