There was once a professor of medicine, who was very strict with his students. Whenever he took the chair on the exam committee, the students would be in fear, because he was seldom pleased with the answers they gave. A student would be lucky enough if he or she could receive a good mark from him. At the end of the term, the students of medicine would take their exam again. Now a student entered the exam room and got seated before the committee. This student was a little nervous as he knew it would not be so easy to get through the exam at all. The professor began to ask. The student was required to describe a certain illness, his description of which turned out to be OK. Then the professor asked about the cure for the illness, and the student, too, answered just as right. "Good," said the professor, "and how much will you give the patient?" "A full spoon," answered the student. "Now you go out and wait for what you can get," said the professor. At the same time the committee discussed carefully the answers the student had given. Suddenly the student noticed there was something wrong with his last answer. "A full spoon is too much," he thought to himself. Anxiously he entered the room and cried, "Mr. Professor, I've made a mistake! A full spoon is too much for the patient. He can take only five drops. " "I'm sorry, sir," said the professor coldly, "but it's too late. Your patient has died." Before he left the room, the student probably _ . A) believed that he had passed the exam B) thought five drops of medicine would cure the patient C) knew he had made a mistake D) felt he had not done well in the exam

More and more people take part in marathons these days - over 30,000 people will run the London Marathon this weekend, for instance. But it's not just the 26 miles and 385 yards that could be a daunting prospect. "I have to admit to being completely frustrated by the blocking and for 18-19 miles was just keeping away from people and being held up," one participant grumbled after the 2012 London Marathon. "I had to overtake a lot of people and ended up with bruised forearms from all the elbows," said another. How do such crowding problems arise, and could they be reduced? Some researchers believe that we can find the answers through a more familiar system in which jams appear - road traffic flow. Martin Treiber, of the Technical University of Dresden in Germany, has previously developed models for traffic flow. One of the first attempts to model traffic flow was made in the 1950s by James Lighthill and his collaborator Gerard Whitham of Manchester University. They considered the traffic as a kind of liquid flowing down a pipe, and looked at how the flow changes as the fluid gets denser . At first the flow rate increases as the density increases, since you simply get more stuff through in the same period of time. But if the density becomes too high, there's a risk of jams, and the flow rate drops sharply. Treiber's model of a marathon uses this same principle that the flow rate first increases and then decreases as the density of runners increases, thanks to an sudden switch from free to crowded flow. He assumes that there is a range of different preferred speeds for different runners, which each maintains throughout the race. With just these factors, Treiber can calculate the flow rate of runners, knowing the "carrying capacity" at each point on the route. This allows Treiber to figure out how blocking might depend on the race conditions - for example, for different starting procedures. Some marathons start by letting all the runners set off at once (which means those at the back have to wait until those in... What is the worst thing while running a marathon? A) The long distance. B) Too many participants. C) The dangerous blocking. D) Serious injuries in forearms.

Ques: In many European countries it is normal to have a long break in the middle of the day when all members of the family return to their houses to eat together. This is not very common in Britain because normally it is a long way from the place of work or school to the home. Consequently the British people tend to have a big breakfast before they go to work and the meal at midday is not spent with the members of the family but with workmates or schoolmates. Lunch is normally eaten between 12: 30 p.m. and 1: 30 p.m. Most people finish work at five thirty. It often takes at least an hour to get home from the school or workplace so people tend to eat their evening meal or "dinner" between 6: 30 p.m. and 8 p.m. On Sundays people don't have to work, so they take the opportunity to eat together with their family. Sunday lunch is usually the best meal of the week and many of the meals which are considered typically British are eaten for Sunday lunch. For example roast beef and Yorkshire pudding. This is a typical British family eating together on Sunday. After lunch the father will smoke his pipe and read the newspaper sitting on his favorite armchair while his wife washes the dishes. The children will play traditional English games such as hopscotch, skipping or doctors and nurses. Although everyone in Britain understands that "breakfast" is the first meal of the day, there is a lot of confusion about the words for other meals such as "dinner, lunch, tea, high tea, brunch and supper" and if you ask a British person what these words mean, most of them will give you a different answer according to what part of the country they are from or what social class they are from. Another example of this is the pronunciation of the word "scones" (a type of cake eaten with Devonshire clotted cream, strawberry jam and cups of tea, known as a "cream tea") The passage is mainly about _ . A) the eating habits in Britain B) British family eating together C) the eating habits in Europe D) British people give you a different answer about meals

Question: At thirteen, I was diagnosed with kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not. In my first literature class, Mrs.Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said,"Mrs.Smith, you see, the doctor said I have attention problems. I might not be able to do it." She glanced down at me through her glasses, "you are no different from your classmates, young man." I tried, but I didn't finish the reading when the bell rang. I had to take it home. In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system of raised dots , which opened up a whole new world of knowledge to the blind. Wasn't I the "blind" in my class, being made to learn like the "sighted" students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up? I didn't expect anything when I handed in my paper to Mrs.Smith, so it was quite a surprise when it came back to me the next day- with an"A" on it. At the bottom of the paper were these words:" See what you can do when you keep trying?" What is the main idea of the passage? A) The disabled should be treated with respect. B) A teacher can open up a new world to students. C) One can find his way out of difficulties with efforts. D) Everyone needs a hand when faced with challenges.
