A. give B. have f C. learn D. makeIII. 阅读理解A) I have never taken cooking classes. I learned cooking from my mother because she was really interested in teaching me how to cook. The main reason for this was because when my mother got married, she didn’t know how to cook anything, not even an egg. My grandmother never allowed her to stay in the kitchen when she was cooking.My mother did not start to cook until she was 25 years old. In the beginning, it was very hard for her. Therefore, she had to take cooking classes to prepare our meals. After having that experience, she decided to teach me how to cook because she didn’t want me to have the same experience.I remember when I was seven years old, and my other was cooking, I was with her in the kitchen enjoying cooking.I always helped her. Sometimes we prepared meals that my mother already knew how to make, and sometimes we prepared them from recipes. Nowadays, I am really thankful for that experience because I don’t need help to cook a meal.I can cook for me alone or for a group of people; it doesn’t matter.I will do the same with my children because I don’t want them to have the same experience as my mother. If one day I am not with them, I want to be sure that they can carry on their lives without me.41.

The four texts above are most probably ______.A. lettersB. noticesC. invitationsD. advertisementsC) Many years ago when people had no thermometers(温度计), they usually touched a thing to see how hot or cold it was. The following experiment shows easy it was to make a mistake.Take three glasses: the first one with very hot water, the second one with very cold water, and the third one with water at room temperature. Then you put a finger of one hand in the hot water, and a finger of the other hand in the cold water. You hold your fingers in the two glasses for a That is minute. Then you use each finger, one after another, one after another, to see how hot or cold the water in the third glass is. You will find that the water is warm to the finger that was in the cold water before, but the finger which was in the hot water will feel cold in the same glass of water.That is why you must always find the temperature in a scientific way. You must not try to tell the temperature as it seems to you.You will often make a mistake if you take something that seems to you for a real fact. For example, when you are going to an Amusement park by bus and you want to get there very quickly, it seems to you that your bus is going very slowly, slower than the other buses. But if it is Sunday and you have much free time, it seems to you all the buses and cars are going very fast.51. The experiment tells us that sometimes it is ______ to make a mistake.A. interestingB. difficultC. easyD. helpful52. The water in the third glass is ______.A. colder than the water in the first glassB. hotter than the water in the first glassC. colder than the water in the second glassD. as cold as the water in the second glass53. What will you find if you put the finger which was in the first glass into the second glass according to theexperiment?A. The water is hotter than it is in the first glass.B. The water is as hot as it is in the first glass.C. The water is at room temperature.D. The water is colder than it is in the first glass.54. How should we find the temperature according to the passage?A. Try to tell as it seems to us.B. Try to use our fingers.C. Try to tell in a scientific way.D. Try to touch something to see how hot it is.55. We can learn something about ______ from the passage.A. physicsB. chemistryC. psychology(心理学)D. biology(生物学)IV56a meal. Today, fast food is 57 cheap, which makes it even more attractive. And it is everywhere—not only in the United States 58 around the world. Now, 59 , there is a group of people who would like to see us stop 60 so much fast food. These people belong to the Slow Food Movement.The Slow Food Movement started in Italy in 1986. It was 61 by Carlo Petrini, a food critic who 62 owned a restaurant. He and his friends wanted to encourage more people to slow 63 and learn to prepare and enjoy good food again. 64 began by meeting in small 65 to organize dinners and wine tastings. They also began to encourage 66 local farmers to go back to the old ways of growing food and caring for farm animals. They felt that food that was raised carefully tasted 67 .This small Italian group grew, 68 in 1989 the International Slow Food Movement was born in Paris. Today there 69 78,000 members in 100 countries. There is also a 70 magazine, printed in six languages, including Japanese.V. 短文改错Cell phones can be see almost everywhere in 71. ________school now.

说明：多项式乘法的结果一般是按某个字母的降幂或升幂排列．
【公式 2】 (a + b)(a 2 − ab + b2 ) = a3 + b3 (立方和公式)
证明: (a + b)(a 2 − ab + b2 ) = a3 − a 2b + ab2 + a 2b − ab2 + b3 = a3 + b3
2(x + 3)(x − 3)
2(x + 3)(x − 3) 2(x + 3)
说明：(1) 分式的乘除运算一般化为乘法进行，当分子、分母为多项式时，应先因式分解再进行约分化简；(2) 分式的计算结果应是最简分式或整式．
4、…、10 的立方数，是非常有好处的．
【例 4】已知 x 2 − 3x = 1 = 0 ，求 x3 + 1 的值． x3
解： x2 − 3x = 1 = 0 ∴ x ≠ 0 ∴ x + 1 = 3
x
原式= (x + 1 )(x2 −1 + 1 ) = (x + 1 )[(x + 1 )2 − 3] = 3(32 − 3) = 18
a3 + b3 = (a + b)[(a + b)2 − 3ab] = −c(c2 − 3ab) = −c3 + 3abc ∴ a3 + b3 + c3 = 3abc ②，把②代入①得原式= − 3abc = −3
abc
说明：注意字母的整体代换技巧的应用．引申：同学可以探求并证明：
a3 + b3 + c3 − 3abc = (a + b + c)(a 2 + b2 + c 2 − ab − bc − ca)

4．下列关于电解质电离的叙述中正确的是()A．CaCO3在水中溶解度很小，其导电能力很弱，所以CaCO3是弱电解质B．CaCO3在水中溶解度很小，但溶解的CaCO3全部电离，所以CaCO3是强电解质C．氯气和氨气的水溶液导电性都很好，所以它们是强电解质D．水难电离，纯水几乎不导电，水是非电解质【答案】B【解析】CaCO3不是弱电解质，因为溶解的部分全部电离，氯气和氨气在水中均不能电离出离子，它们不是电解质，之所以能够导电是因为生成了电解质HCl、HClO和NH3·H2O。

水是极弱的电解质。

And why couldn’t you see it? When you look into a mirror, you don’t see your face as other people see it. You see a reversed picture. If you close your left eye, your picture closes its right eye. If you touch your right ear with your right hand, your picture touches its left ear with its left hand.If you have two small mirrors, you can see your faces as your friends see it. You hold the two mirrors at right angles(角度) to each other and look into them. After some practice you will be able to see the real picture of your face.Now close your left eye and your picture closes its left eye too. Touch your right ear with your right hand and your picture touches its right ear with its right hand! This happens because each mirror reflected(反射) the picture in the other mirror. So you see a reversed picture of a reversed picture, which, of course, is the same as the real picture.1.
