Article: My first experience of modern city life was quite impressive. I was very curious when I arrived in London. First, I noticed so many people were on a trip in a busy way.  When I first saw the machine on the underground where you are expected to feed your ticket in and have to run through moving barriers  , I was completely fascinated   at it. Flashing with the light, the little green man, telling you when to cross the road, was also quite interesting, and so were those street advertisements which kept changing subjects as you look.  In my native place, my life is so different from people's here. I am a market gardener from Makono, a village which is led by a market-managing group. People there usually walk two hours a day to get water from a well. What's more, I am used to going, for many hours, without drinking , so it was strange to be offered cups of tea all the time here in London.  In my native place, on market days, I usually walk for several hours with my basket full of fruits and vegetables on my head, carrying them to the market for sale, to earn PS1per basket. Without the produce from my garden, I could not pay for education or healthcare for my children. Gardening is not a hobby for me - it's  _ . But here people are planting something only to kill their leisure time.  During our visiting-time in Britain, we visited some local government agencies, schools, churches and farms in Sussex, Scotland, Yorshire, Loncolnshire and Cambridgeshire, meeting people who were of the same profession as we are. Children in Burley-in-Wharfedale, Yorkshire, prepared a special get-together to greet us and we were also asked a lot about our life which was quite fascinating to them. For example, how we make our houses out of mud and how we get our water for our daily necessities, as well as for our garden. 
 Question: The most disadvantage in the writer's native place should be that   _   . 
 Options: (A) there are many market-managing groups for gardeners (B) the lack of water makes the life there even harder (C) people there like to travel about on foot for enjoyment (D) people support themselves using the garden produce
answer:
B


question:
Article: In the new book The Education of Millionaires,Michael Ellsberg suggests that although"there are many wonderful things you can learn in college,"few of them are applied to real life .So Ellsberg has written the book to tell"the capabilities and attitudes that will get you improved outside the classroom." I welcome the kind of debate about the value of higher education.It is necessary to remember, however,that Ellsberg also tells how important it is to make money.He mentions a number of college dropoutssuch as Bill Gates and Michael Dellto show how successful they have become without the benefit of a college degree.While Ellsberg stresses the achievements of dropouts,he includes degree holders who have become wealthy and famous.For example,of the current Fortune 500 CEOs,some 99%have a college degree.Similarly,of the Forbes 400 richest people in America,81%hold postseconda.ry degrees. But in the discussion,what is forgotten about the value is that the purpose of education is not simply to enable one to earn a living but to prepare one for living over the course of life .What is also left out of the debate about higher education is that its purpose is not just to provide a pathway covered with gold for the nation's elites .If we have the discussion that way,we may look down upon the people who devote themselves to other ordinary jobs that form the basic structures of our society,Though these individuals may not be reaching for the kind of stars that Michael Ellsberg and others would have them grasp,most are doing something even more important:they are involved in the useful tasks of good citizens and contributing to the common welfare,including providing for their families. 
 Question: In the book The Education of Millionaires,Michael Ellsberg  _  . 
 Options: (A) approves of the value of education (B) explains the reasons for dropping out (C) tells the way of getting out of college (D) discusses the practical value of college degrees
answer:
D

Article: Sheep, like turkeys and ostriches, are not considered the cleverest animals. British scientists said last Wednesday human may have underestimated  the woolly creatures. They could be much smarter than we think. Researchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good at recognizing faces--which they think is a sure sign of intelligence. Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish  25 pairs of sheep faces and used electrodes  to measure their brain activity, which showed they could remember 50 faces for up to two years. "If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else," Kendrick said in an interview. So hours of seemingly mindless eating grass may not be so mindless after all. Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much ind ividuality and are frightened of just about everything. All animals, including humans, once they are frightened don't tend to show signs of intelligent action," he explained. In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar. "The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time," said Kendrick. "It is a very strange system. They are showing similar abilities in many ways to humans. " 
 Question: From what Kendrick said in the interview we learn that   _  . 
 Options: (A) scientists have learned a lot about sheep's intelligence (B) scientists have learned little about sheep's intelligence (C) scientists can't do anything more about sheep's memory (D) scientists don't have to research animals' memory
answer:

B
