Question

It’s possible to do many simple tricks with numbers. Here is one trick, if you follow the instructions, you will find it’s really interesting.
First, write down your house number. For example, if your address is 73 Jin Shang Road, you would write down 73. After you write down your house address number, you double it. Then add 5 to this doubled number. For example, if your address is 73 and you double it, you will get 146. Then you add 5, you will get 151.
And then, multiply this number by 50. In our example here, you’ll get 7550. The next step is to add your age to this total. For example, if you’re 16 years old, you should add 16 to this total. In our example here, the result will be 7566.
After that, you have to add the number of days in a year, which is 365. In our example here, 365 added to 7566 is 7931.
The final step is this: Subtract 615 from the number that you have. Take away 615 from the total. In our example, 7931 minus 615 is 7316.
The result here—7316—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 16 is the age that we used.
Isn’t it interesting? Do you want to have a try now?

解析試題分析：短文大意：這篇短文主要講述了一個數(shù)字游戲的步驟，并舉例進行了說明。
【小題1】細節(jié)理解題。根據(jù)短文第二段if your address is 73 Jin Shang Road, you would write down 73. After you write down your house address number, you double it. Then add 5 to this doubled number.及下文And then, ……After that, ……The final step is this:描述，可知這個游戲一共有七步。故選B。
【小題2】細節(jié)理解題。根據(jù)第二段, if your address is 73 Jin Shang Road, you would write down 73. After you write down your house address number, you double it. Then add 5 to this doubled number.描述，可知第三部是＋5，故選A。
【小題3】計算分析題。根據(jù)短文描述，可知我們首先應該將門牌號乘以2，然后加上5，然后再再用他們的結果乘以50，接下來加上自己的年齡和一年的天數(shù)，最后再減去615，據(jù)此解答即可.(89×2+5)×50+38+365－615=8938，故選C。
【小題4】細節(jié)理解題。閱讀短文if your address is 73 Jin Shang Road,可知，73是用來舉例的一個地址。故不是每次都用得到。故選B。
【小題5】標題歸納題。閱讀短文可知，本文主要描述的是一個數(shù)字游戲的游戲步驟。故選A。
