But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue . To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day. So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired. Some scientists declare that most of our fatigue come from our mental and emotional attitudes. One of England's most outstanding scientists. J. A. Hadfield,says,"The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare." Dr. Brill, a famous American scientist, goes even further. He declares,"One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems." What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body. Question: What surprised the scientists a few years ago? Options: A: Fatigue toxinscould hardly be found in a labour's blood. B: Albert Eistein didn't feel worn out after a day's work. C: The brain could wrk for many hours without fatigue. D: A mental worker's blood was filled with fatigue toxins.

Read the article and select the best answer. Article: Last Sunday I made a visit to some new neighbors down the block. No specific in mind, just an opportunity to sit at the kitchen table, have some tea and chat. As I did so, it occurred to me how rare the Sunday visit has become. When I was a kid in New Jersey of the 1960s, Sunday visits were routine. Most stores were closed, almost nobody worked, and the highways, as a result, were not desperate steeplechases they have become today. My family normally traveled eight city blocks to the home of my grandmother, where adults would sit on the front porch and chat while we children played hide-and-seek. The Sunday visit was something to desire strongly. It was the repetition to church, our reward for an hour of devotion, an opportunity to take advantage of the fact that Dad was not at work, we were not in school, and there was no housework that couldn't wait until Monday. Sunday was, indeed, different from the other days of the week, because everyone seemed to be on the same schedule, which means that there was one day when everyone seemed to have time for everybody else. Sunday as a day of rest is, or was, so deeply rooted in the culture that it's surprising to find that, in a short span of time, it has almost entirely lost this association. In my childhood, it was assumed that everyone would either be home or visiting someone else's home on Sunday. But now the question is, "What do you plan to DO this Sunday?" The answer can range from going to the mall, to participating in a road race, to Montreal for lunch. If one were to respond, "I'm making a Sunday visit to family," such an answer would feel strange, which sounds like an echo from another era. I suppose I should be grateful to live in Maine, a state of small towns, abundant land and tight relationships. Even though folks work as hard here as they do anywhere else, the state's powerfully rural feature still keeps at least remnants of the moral of yesterday's America, where people had to depend on one another in the face of economic vagaries and a... Question: The writer's general impression of the Sunday in the past was a day when _ . Options: A: everyone was paying a visit to some relatives far away B: everyone seemed to be free for others C: Dad was not at work while Mom was busy cleaning the house D: nearly every adult would go to church and children weren't at school

Ques: Read the article and select the best answer. Article: NASA has opened the door to the next generation of space discovery by announcing great plans for a base for humans to live on the surface of the moon forever. The project to build a base on the moon will begin soon after 2020, with astronauts living there within four years. The project comes after several excellent scientists and environmentalists asked humans to look beyond Earth to ensure the survival of the species . Eventually, the moon will be a base for humans to explore the solar system and one day land on Mars. NASA began planning for the first moon landing since 1972 when George Bush, the US president, announced his new plan for space exploration four years ago. NASA has already talked about the design of the Orion spacecraft that will replace the old space shuttle fleet in 2010. The plan for the moon base, however, is the first detailed explanation of how NASA intends to prepare for the first manned exploration of deep space and a possible Mars mission within 30 years. Scientists also believe that the south pole on the moon contain rich natural gases such as the rare helium-3 that could be used as fuel for the generation of nuclear power. Besides, teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel. Question: The passage mainly talks about _ . Options: A: the USA's new plan for space exploration B: how to build a base on the moon C: why to ensure the survival of the species D: where to get new natural resources
Ans: A

Read the article and select the best answer. Article: Speech--the act of uttering sounds to convey meaning--is a kind of human action. Like any other constantly repeated action, speaking has to be learned, but once it is learned, it becomes a generally unconscious and apparently automatic process. As far as we can determine, human beings do not need to be forced to speak; most babies seem to possess a sort of instinctive drive to produce speech like noises. How to speak and what to say are another matter altogetner. There actions are learned from the particular society into which the baby is born; so that, like all conduct that is learned from a society--from the people around us--speech is a patterned activity. The meandering babble and chatter of a young child are eventually channeled by imitation into a few orderly grooves that represent the pattern accepted as meaningful by the people around him. Similarly, a child's indiscriminate practice of putting things into his mouth becomes limited to putting food into his mouth in a certain way. The sounds that a child can make are more varied and numerous than the sounds that any particular language uses. However, a child born into a society with a pattem of language is encouraged to make a small selection of sounds and to make these few sounds over and over until it is natural for him to make these sounds and not others. Question: The sounds that a child is able to make are_. Options: A: not as varied as those used in language B: more varied and numerous than those in any language C: far fewer than those needed to form a language D: completely different from the sounds of language
B
