1、游戏类(1)It is possible to do many simple tricks with numbers. Here is one trick. It has seven steps. First, write down your house number. For example, if your address is 73 Lemon Street, you would write down 73. Next, double(翻一倍) it. In other words, multiply(乘) it by two. Then, add five to this double
2、d number. For example, if your address was 73and you doubled it, you would get 146. Then, if you added five, youd get 151. So, to repeat the first three steps, write down your house number, double it, and add five. Fourth, multiply this number by 50. In our example here, if you multiply 151 by 50, y
3、oull get 7550. The fifth step is to add your age to this total. For example, if youre 26years old, you should add 26 to this total. In our example here, the result would be 7550 plus 26, youll get 7576. Sixth, you have to add the number of days in a year, which is 365. In our example here, 365 added
4、 to 7576 is 7941. The seventh and final step is this: subtract(减) 615 from the number that you have. In our example, 7941 minus 615 is 7326. The result here, 7-3-2-6, is the trick. The first part of the number is the address and the last part of the number is the age of the person. That is, 73is the
5、 address that we started with, and 26is the age that we used. If you follow these seven steps with any address and the age of any person. You will get the same result. 1. According to the trick, what number can you get if you are 16 years old and your house number is 85？A. 1685B. 8516C. 8165D. 16582
6、. How can your age number appear at the last part of the result?A. Its really a trick. B. By taking all the steps except Step1 and Step 2. C. By taking Step 6and Step 7. D. By taking all the steps. 3. Whats the secret of the trick?A. Its impossible to know. B. By taking Step 2 and Step 4, we get the
7、 formula(公式)：your address number 250. C. By taking all the steps except 1 and 2, we get the formula: 550+your age number+365615=your age number. D. Both B and C. 4. Is it possible for us to design another program of getting the same result？A. No, its impossible to find out another way. B. No problem
8、. C. Im not sure. D. Its nothing but a trick. 【答案与解析】 本文主要介绍一个数学的小把戏。1. B。推断题。由文章的倒数第2段，“The first part”我们可以得出这条算术的答案：共有四位数字，前两位是地址的号码，后两位是年龄的数字，所以答案是B。2. D。推断题。只有将步骤全部算完才可以得出答案，因此选D。3. D。推断题。通过选项B的公式可以算出地址号码的100倍，即答案的前两位数字；通过选项C可以算出年龄的数字，也是答案的后两位。将B，C两项加起来就揭开了把戏的秘密，据此可推出答案为D。4. B。推理题。根据常理，我们知道数学的奥妙
9、是无穷的，所以设计另外一条程序是完全没有问题的，所以选B。 (2) “Youre just in time, Joe.

Careful timing is needed to turn a rope. 【答案与解析】本文是介绍怎样有技巧地玩跳绳这种游戏。1. A。全文的每一个段落都在讨论rope jumping，即跳绳这种Game。2
23、. C。由文章的第1段You can jump alone or with your classmate，既然是alone或with classmate，我们可以得知跳绳是一人或一人以上玩的游戏。3. B。第1段的最后一句讲到Try ropes of different lengths until you find a right one for your size(试试各种不同长度的绳子，直到你找到适合你的身材的一个 right on)，据此显然可推出其中的one指的是“绳子”。4. B。文章的第1段最后两句告诉我们If you jump alone, you，所以玩跳绳以前，必须找到适合自己的绳子。5. D。我们可以在第2段找到Turning the rope freely and safely needs careful timing，这是与D项完全对应的；另外，文中说的是slowing enough，而不是像A、B项所说的as slowly as possible和as high as possible，故排除A和B。根据文章最后一段中的You must learn when to stop for a rest before you jump again可将C项排除。.精品资料。欢迎使用。高考资源网w。w-w*k&s%5￥u高考资源网w。w-w*k&s%5￥u
