In general people talk about to groups of colors: warm colors and cool colors. Scientists think that there are also two groups of people: people who prefer warm colors and people who prefer cool colors.

The warm colors are red, orange and yellow. Where there are warm colors and a lot of light, people usually want to be active. People think that the people who prefer red are exciting social(善交际的) people, and like to be with others who like red. The cool colors are green, blue and purple. These colors, unlike warm colors, are exciting. Where there are cool colors, people are usually quiet. People who like to spend time alone often prefer blue.

Red maybe makes people exciting, but one scientist says that time seems to pass more slow in a room with warm colors than in a room with cool colors. He suggested that a warm color such as red or orange is a good color for a living room or a restaurant.

People who are relaxing or eating don?t want time to pass quickly Cool colors are better for offices of factories as the people who work there want time to pass quickly . Scientists don?t know why people think some colors are warm and other colors are cool.

However, almost everyone agrees that warm colors remind people of warm days and cool colors remind them of cool days. Because the sun is higher during summer, the hot summer sunlight appears yellow.

41. When people talk about two groups of people, they mean two kinds of people who ___ respectively. A.are warm colors and cool colors B. are green, blue and purple C.like warm colors and cool colors D. are yellow, red and orange 42.The people who like warm colors_____.

A. don?t like to be with others B. like to stay at home by themselves C. are very hard to get on with D. are very easy to get on with others

43. Which of the following statements is NOT true?

A. Maybe warm colors make people think of warm days. B. The writer thinks cool colors are good for offices of factories.

C. Time seems to pass more slowly in a room with warm colors than in a room with cool colors. D. The persons who are relaxing don?t want time to pass slowly.

44. Why do some people who like warm colors and others like cool colors? A. Because the people who like warm colors are active. B．The writer doesn?t tell us the reason, so we don?t know why. C. Because warm colors are nice and cool colors are not nice.

D. Because the people who like cool colors prefer staying at home alone. 45. Which of the following may be the best title for this passage?

A. Cool Colors. B. Two Groups of Colors. C. Colors and People. D. Warm Colors.

(B)

What will man be like in the future-in 5000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time.

Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively short period of time, so we may assume（假定） that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain?s capacity. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger.

Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over very long period of time it is likely that man?s eyes will grow stronger.

On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.

But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald（光秃）.

Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. 46.. The passage mainly tells us that____. A. man?s life will be different in the future

B. future man will look quite different from us

C. man is growing taller and uglier as time passes D. man?s organs? functions will be one the wane

47. The reason for believing that future man will be different is that he ____. A. is always growing B. never stops changing C. hopes for a change D. will live a different life 48. Man?s forehead will grow larger because____ A. he makes use only 20 % of the brain?s capacity. B. his brain has grown larger over the past centuries. C. the other 80% of his brain will grow in due time.

D. he will use his brain more and more as time goes on. 49. What will be true about a human being in the future? A. He will be hairless because hair is no longer useful. B. He will have smaller eyes and wears better glasses.

C. His fingers will grow weaker because he doesn?t have to make use of them. D. He will think and feel in different way. 50.It is implied that ____.

A. human beings will become less attractive in the future.

B. less use of a bodily organ may lead to its degeneration（退化、衰退） C. human beings hope for a change in the future life D. future life is always predictable.

(C)

How should one invest a sum of money in these days of inflation（通货膨胀）? Left in a bank it will hardly keep its value, however high the interest rate．Only a brave man, or a very rich one, dares to buy and sell on the Stock Market．Today it seems that one of the best ways to protect your savings and even increase your wealth is to buy beautiful objects from the past．Here I am going to offer some advice on collecting antique （古董） clocks, which I personally consider are among the most interesting of antiques．

I sometimes wonder what a being from another planet might report back about our way of life．“ The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound．It has a face with twelve black marks and two hands．Men can do nothing without its permission, and it fastens its young round people?s wrists so that everywhere men go they are still under its control．This creature is the real master of Earth and men are its slaves.”

Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time．Certain men were very clever at measuring the time of day according to the beating of their own hearts．They were made to stand in a fixed place and every hour or so would shout the time．So it seems that the first clocks were human

beings.

However, men quickly found more convenient and reliable ways of telling the time．They learned to use the shadows cast by the sun．They marked the hours on candles, used sand in hour-glasses, and invented water-clocks．Indeed, any serious student of antique should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.

Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home．After all, if you are going to be ruled by time, why not invest in an antique clock and perhaps make a future profit? 51．According to the passage, collecting antique clocks___________.

A．can hardly keep the value of your savings B．will cost much of your savings C．may increase your wealth D．needs your bravery

52．By quoting （引用） the remark （话） of a being from another planet, the author intends to ________________.

A．suggest human beings are controlled by a clock B．describes why clocks can rule the planet Earth C．tell readers what clocks look like D．compare clocks to human beings 53．Which of the following is NOT mentioned as a way to measure the time?

A．Counting the beating of one?s own heart. B．Making use of candles, sand and water. C．Observing shadows cast by the sun. D．Keeping all the slaves busy day and night. 54．The underlined phrase stately homes in paragraph 4 means ____. A．state-owned houses B．houses in very good condition

C．grand houses open to the public D．houses where statesmen meet regularly 55．The purpose of the passage is ________________. A．to introduce the culture of antique clocks B．to offer some advice on collecting antique clocks C．to compare different ways to make a future profit

D．to explain convenient and reliable ways of telling time 五、词义搭配（10）

56. familiar A. cover a large area of period of time 57. personal B. brave, fearless 58. courageous C. know; identify again. 59. perform D. knowing sth. very well

60. establish E. fasten or bind with rope, wire, etc. 61. spread F. belong to a particular person. 62. capable G. act a play 63. recognize H. set up

64. affect I. having the ability

65. tie J. have an influence on 六、补全对话。

Phyllis: What?s the matter, Anne? Anne: Yes. I have a chance to get another job and don?t know what to do. Phyllis: If it is a better job than you have now, take it. That?s my idea.

Anne: . I like the job I have now very much. The people in my office are very nice and

my work is interesting.

Phyllis: What about the salary? That would influence me if I were me.

Anne: If I accept the job, I?ll get more money right away. What should I do? I have

to let them know my decision today.

Phyllis: . I?ll be anxious to know what you do. I?d like to try to get that new job, if you

decide not to take it. A: It isn?t as easy as that, Phyllis. B: Do you have a problem? C: Would you get more money?

D: You?ll just have to decide for yourself, Anne. E: Yes, the salary is better. 七、单词拼写。

第三篇：高一上学期数学教学工作总结

20xx—20xx学年古浪五中高一学期

数学教学工作总结

古浪五中 张子杰

时间过得真快，转眼间高一上学期的工作就结束了。

回想起这学期的工作，我感受颇多。这学期，我担任了高一（7）班班主任及高一（4）、（7）班的数学教学工作。首先，我想就数学教学工作谈谈我及我们备课组的一些做法：

一、对学生严格要求，培养良好的学习习惯和学习方法

学生在从初中到高中的过渡阶段，往往会有些不能适应新的学习环境。例如新的竞争压力，以往的学习方法不能适应高中的学习，不良的学习习惯和学习态度等一些问题困扰和制约着学生的学习。为了解决这些问题，我确实下了一翻功夫。

1、改变学生学习数学的一些思想观念，树立学好数学的信心

在开学初，我就给他们指出高中数学学习较初中的要难度大，内容多，知识面广，让他们有一个心理准备。我们班是一个重点班，全班大多数同学初中升高中成绩比较差，这造成一些成绩相对较差学生有自卑感，害怕自己不能学好数学；相反有些成绩较好学生骄傲自大，放松对数学的学习。对此，我给他们讲清楚，大家其实处在同一起跑线上，谁先跑，谁跑得有力，谁就会成功。对较差的学生，给予多的关心和指导，并帮助他们树立信心；对骄傲的学生批评教育，让他们不要放松学习。

第一次月考，全班很多同学考得不好，甚至有个别同学只有三、四十分。有个以前成绩较好女生哭着对我说，她从来没有考过这么低的分，对学好数学没有信心。我耐心给她分析没考好的原因，一是试卷的难度大，二是考查的知识点上课时没能重点掌握，三是没有做好复习工作，教给她要注意的地方。全班基本上树立了能学好数学的信心。

2、改变学生不良的学习习惯，建立良好的学习方法和学习态度

开始，有些学生有不好的学习习惯，例如作业字迹潦草，不写解答过程；不喜欢课前预习和课后复习；不会总结消化知识；对学习马虎大意，过分自信等。我要求统一作业格式，表扬优秀作业，指导他们预习和复习，强调总结的重要性，并有一些具体的做法，如写章节小结，做错题档案，总结做题规律等。对做得好的同学全班表扬并推广，不做或做得差的同学要批评。在我的严格要求下，大多数同学能很快接受，慢慢的建立起好的学习方法和认真的学习态度。当然，要改变根深蒂固的问题并不容易，这学期还要坚持下去。

二、刻苦钻研教材，不断提高自身的教学教研能力

高一虽然已经教过了几轮，但是每一年的感觉都不一样。从不敢因为教过而有所懈怠。我还是像一位新老师一样认真阅读新课标，钻研新教材，熟悉教材内容，查阅教学资料，适当增减教学内容， 认真细致的备好每一节课，真正做到重点明确，难点分解。遇到难以解决的问题，就向老教师讨教或在备课组内讨论。另外，我还积极阅读教学教参书籍及教学论文，如《中学数学教学参考》等，认真学习各种教学方法，并尝试运用到实践教学中去，当然，还有很多是不成熟。

积极参加各种教研活动，如集体备课，校内外听课，教学教研会议。努力提高课堂教学的操作调控能力，语言表达能力，运用多种教学器材，为了节省时间和增加课堂容量，我坚持用多媒体课件上课。课下，根据自己的理解，选题、出检测试卷，这样也提高了我对教材重难点的理解。

积极安排时间做好学生的辅导工作，学生有问题及时解决。

坚持了一个学期，我感觉收获颇多。

三、备课组的精诚合作是取得成绩的关键

如果说高一数学取得了一点成绩的话，那也是我们备课组在教学能力强、经验丰富的何艳文组长的带领下，团结合作的结果。我们的备课组做事非常齐心。我们坚持集体备课。集体备课使我们对教材的认识达到统一，理解更深刻，时间安排一致。除了规定的时间集体备课外，我们还经常在一起讨论，解决问题。其次，统一测试、统一复习资料。平时，备课组安排老师出单元资料、检测题，然后统一使用。在期末复习阶段，组长安排每个老师负责出各章节的复习资料、复习题，资料共享。所以，最后的成绩是我们备课组全体老师共同努力的结果。

四、存在的困惑： 1．书本习题都较简单和基础，而我们的教辅题目偏难，加重了学生的学习负担，而且学生完成情况很不好。课时又不足，教学时间紧，没时间讲评这些练习题。

2．在教学中，经常出现一节课的教学任务完不成的现象，更少巩固练习的时间。勉强按规定时间讲完，一些学生听得似懂非懂，造成差生越来越多。而且知识内容需要补充的内容有：因式分解的十字相乘法；一元二次方程及根与系数的关系；解不等式等知识。

3．虽然经常要求学生课后要去完成教辅上的精选的题目，但是，相当部分的同学还是没办法完成。学生的课业负担太重，有的学生则是学习意识淡薄。

五、今后要注意的几点

1．要处理好课时紧张与教学内容多的矛盾，加强对教材的研究；

2．注意对教辅材料题目的精选；

3．要加强对数学后进生的思想教育
