高考臨近，以下是一篇高考英語閱讀理解模擬題，希望對(duì)大家有所幫助！
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 it. In other words, multiply(乘) it by two. Then, add five to this doubled number. For example, if your address was 73 and you doubled it, you would get 146. Then, if you added five, you’d get 151.
Now 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, you’ll get 7550.
The fifth step is to add your age to this total. For example, if you’re 26 years old, you should add 26 to this total. In our example here, the result would be 7550 plus 26, you’ll get 7576.
Sixth, you have to add the number of days in a year, which is 365. In our example here, 365 added to 7576 is 7941.
The seventh and final step is this: subtract(減) 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, 73 is the address that we started with, and 26 is 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.

C. By taking all the steps except 1 and 2, we get the formula: 5×50+your age number+365-615=your age number.
D. Both B and C.

【答案與解析】
1. B。根據(jù)文章倒數(shù)第3段的The first part of the number is the address and the last part of the number is the age of the person可以得出答案：共有四位數(shù)字，前兩位是地址的號(hào)碼，后兩位是年齡的數(shù)字，所以答案是B。
2. D。只有將步驟全部算完才可以得出答案，因此選D。
3. D。通過選項(xiàng)B的公式可以算出地址號(hào)碼的100倍，即答案的前兩位數(shù)字;通過選項(xiàng)C可以算出年齡的數(shù)字，也是答案的后兩位。將B，C兩項(xiàng)加起來就揭開了把戲的秘密，據(jù)此可推出答案為D。
4. B。假設(shè)某人的address號(hào)碼為m，其年齡為n，那么根據(jù)上面游戲規(guī)則，我們可以得出以下公式：(m×2+5) ×50+n+365-615。把該公式展開即可得到：(m×2×50+5×50+n+365-615。通過簡單計(jì)算我們可以得以下結(jié)果：m×100+n。顯然，這個(gè)數(shù)的千位和百位為address號(hào)碼，十位和個(gè)位為年齡。據(jù)此原理，我們可以設(shè)計(jì)出無數(shù)個(gè)可以得到同樣結(jié)果的方案，比如我們可以將游戲中第三步中的加5改為加6，將第七步中減615改為減665，其結(jié)果也完全一樣的;或者將游戲中第三步中的加5改為加7，將第七步中減615改為減715，其結(jié)果也完全一樣的;或?qū)⒂螒蛑械谌街械募?改為加8，將第七步中減615改為減765，其結(jié)果也完全一樣的;等等。
