Of these, only about half a dozen becomes the strong, circling winds of 75 miles per hour or more that are called hurricanes, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people. The great storms that hit the coast start as soft circling wind hundreds -- even thousands -- of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the southeast winds. When conditions are just right, warm, moist air flows in at the bottom of such a wind, moves upward through it and comes out at the top. In the process , the moisture in this warm air produces rain, and with it the heat is changed to energy in the form of strong winds. As the heat increases, the young hurricane begins to move in a counter-clockwise motion . The life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane's rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months. Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12 inch downpours, causing sudden floods. Worst of all is the powerful movement of the sea -- the mountains of water moving toward the hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore. Question: Here the word "downpour" means _ . Options: A: heavy rainfall B: dangerous waves C: the progress of water to the hurricane center D: the increasing heat

Article: "The price of books for our students is just getting higher and higher and,combined with the rising cost of tuition,it's killing these students,"said Peter Jason,a college professor."Remember,students are one of the poorest groups of people in America.Almost half of them have at least one part-time job.In fact,one of my students has three jobs.And she still manages to have high scores and go to school full-time." Textbook prices are traditionally high.Adding to that problem,many college teachers change textbooks year after year;they either upgrade to a new edition or switch to an entirely different textbook.This further hurts students because if an instructor no longer uses a particular textbook,that book has no resale value. Dr.Jason decided to make lire a little easier and a lot cheaper for his students by writing his own book on public speaking."Many books have an increased price because of CD-ROMs,lots of color photographs and pictures.I talked to my students,and many of them,like me,prefer to keep things simple! So,a few years ago,I wrote my own textbook.Compared to most other public speaking books,mine is half the number of pages,and one-third the price.That is,$30 instead of $90.When I wrote a second edition last year,students only had to buy the 35 new pages, For only $7.00,they had almost a new book. Now my loose-leaf textbook enjoys great popularity among the students.Maybe in the future more writers and publishers will try it." Question: What did Dr. Jason say about students at college? Options: A: They are short of money. B: They need better textbooks C: They should do part-time jobs. D: They are trying to get high scores.

Q: Read the article and select the best answer. Article: American scientists have developed the first material that repairs itself. The material is a form of plastic that has been engineered to fill breaks in its surface. Plastics are used today in everything. Scientists wanted to find a way to make objects made of plastic last longer. The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace. The surface of plastic objects breaks over time. Very small breaks develop every time a plastic object is used. The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it. They found the answer in the chemical structure of plastic itself. The research team found a way to make plastic that contains very small balloons filled with monomer liquid. When the new plastic cracks, the monomer liquid is let out and flows into the crack. Thus the break is repaired. The repaired plastic has seventy-five percent of the strength of undamaged plastic. The new self-repairing plastic is not yet ready for production. But it has several possible uses. One could be in space vehicles where parts cannot be repaired or replaced. Another possible use might be in bridges. And it could be used in people, to replace bone joints that have become broken or damaged. Question: We know from the passage that the repair is done as _ . Options: A: the cracked plastic parts are changed B: the plastic cracks C: the liquid is put into the plastic cracks D: the plastic is made
A: B
