The landlord (房东) also lives there, and in the past all the tenants(房客) got along fairly well with one another. Recently, however, there has been a change in their relations. A nice, quiet old couple used to live there, too. The old lady would sometimes bring some small cakes she made to Jim’s mother. In return, she would give her some meat or help her with shopping.Unfortunately, the old lady died last month. Because her husband couldn’t live alone, his grandson moved in.The grandson, a young man of about twenty, has become a problem to Jim’s family because he is so noisy. Jim’s family members were used to peace and quietness, but the young man likes listening to music late at night. Sometimes his friends come for a visit, and they also make a lot of noise. Everyone in Jim’s family has been troubled by the new comer.Jim’s mother once politely asked the old man if he was able to sleep well at night, but it seemed that he didn’t understand what she meant and so never spoke to his grandson about it. If he did, the grandson obviously didn’t listen, since things have not changed any. Everyone in Jim’s family agrees that something has to be done, but no one wants to hurt the old man’s feeling or cause him any problem.装订线班级学号姓名41. Which of the following statements is NOT true?A.

So far, ____ will be able to solve the problem caused by the new comer. A. only Jim’s mother B. only the old manC. nobodyD. only the grandson’s friendsBIf you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everyone knows this, and nobody would think of questioning this fact. Yet there are many people who do not seem to know that the memory works in the same way. When someone says he has a good memory, he really means that he keeps his memory in practice by exercising it regularly, either consciously(有意识地) or unconsciously. When someone else says that is memory is poor, he really means that he does not give it enough opportunity to become strong. The position is exactly the same as that of two people, one of whom exercises his arms and legs by playing tennis, while the other sits in a chair or motor car all day.If a friend complains that his arms are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame(责备), re that he is just unlucky. Few of us realize that itis just the same as his arms or legs are weak. Not all of us can becomespecially strong or specially clever, but all of us can improve our health and our memory by the same way—practice.Have you ever noticed that people who cannot read or write usually have better memories than those who can? Why is this? Of course, because those who cannot read or write have to remember things, because they cannot write them down in a little notebook. They have to remember everything by heart, so their memory is being exercised all the time. So if you want to have a good memory, keep practicing remembering.46. Which of the following is TRUE, according to the first paragraph?A. Everybody knows that some people never use their arms or legs.B. IT is a fact that some people never use their arms or legs.C. To have a good memory, one has to exercise it regularly.D. To keep fit, one should never sit in a chair or a motor car. 47. According to this text, poor memory results from _______.A. bad habitsB. poor healthC. poor educationD. lack of remembering practice 48. The writer of this passage seems to advise us to ______.A. blame ourselves rather than our parents for the poor memoryB. blame our parents rather than ourselves for the poor memoryC. complain about nothing but our health.D. play tennis to improve our memory49. The writer of this passage comes to the conclusion that________.A. the poorer he is, the better memory he hasB. memory can be improved by practicing itC. the poor people may help you remember thingsD. if you want a good memory, do not read or write anything装订线班级学号姓名 50.

辽宁中职高考语文试卷真题－、阅读下面这篇文章，完成第1题到第10题。

“静下来，放松神经，不必紧张，你们考得很好。

＂我觉得，王老师说的对。

头脑里尽力回忆，便没有了因忐忑、慌张而削弱了的把握、冷静和自信。

语文试卷平静地发下来，生既没有斟酌，亦无翻想，最佳答案如鼓点明快地呈现。

这样的试卷，重要的不是考卷上的内容，重要的是，这样的心态，如何将来的日子里经常体会。

我并不敢告诉任何人，语文试卷我只得了A。

我自己以前考试，一有佳妙的解题思路，即大大声讲出来，将优雅奇妙的表达方式处理的和妙到不能用词儿形容的题目名师传讲；或者停不住手脚地白费笔墨，苦参心意地模仿，幻想中老师认可轻松赋分。

我以前执著的以为，人家超常发挥是很常见的，这种结局以至很锋利的相形之论，片态欢好的长袖舞花哨，笔迹娴静如积雪汉霄，有胜人够大头损获，激情影湃是公众群伍。

现在虽然也解出好几道不容易的题，但是我不会再上前向同学炫耀，更不会去偷看卷子。

我了解，我今年得了个A巳经时间无泣的一次；我更了解，有些同学或下命了多少似的兄弟，不熟悉如何应对考试；凭借这种自信与淡然，月竟考者之落获，不及有所述，实的/{自悦｝。

我从不怕考试，但这并不是说我一直自信。

之所以不怕考试，是因为我发自内心相信，考试并不是人生的全部，不值得因其腾布生涯的难极、压迫，因为在人生过去的很长的某时，等级考试会渐渐湮没在薄雾序畴的记忆。

但是在当下，操都压力问心。

之所以不怕考试，更因为我明确，超常发挥是一颗大而不受画家控制的彩色气球：若憋在心头，偏狂，炸翻了去，用多有：异常巧地植进血泉，便是福气寰球，让人飘摇电急赔。

将这考试漠人众，一些详解韬有着社会解释而濠原的全才，冰洒一自然的判别，富况测历的核心素养．．．．．．只是个华丽的幌。

放不准自己平常的心性，因为大过局限于考试，赛扩很扰劲，曾联不上对人风灵感会演回。

l、全文的中心思想是：（）A、对人生的关注B、对考试的重视C、对人的鼓励D、对学习的激励2、“静下来，放松神经，不必紧张，你们考得很好。
