Now boys and girls，let’s begin our class．As I know, you are interested in some strange math problems．So today I’m going to tell you one of the strangest ways to multiply numbers of two or more figures．Maybe you don’t know the word “multiply”．The word “multiply” mean s“乘．．．，乘法的乘”in Chinese．For example，8 multiplied by 2 is l6．It means “8乘以2是16” in Chinese．Do you understand now? Of course．there are many ways to multiply numbers．But here is one of the strangest．

Imagine you wish to multiply 23 by 17．In Chinese，it means 23乘以17．Half of 23 is 11．5．Write only 11 under 23 as you see in the paper．Half of 11 is 5．5．Write only 5 under 11．Now think it over, what number will you write under 5? Yes, you are right, just 2．Now please write the number under 5．Continue until you have 1．

Now write numbers under 17．But this time you must multiply each number by two to write the number under it．For example, you should write 34 under 17．As a rule, what number will you write under 34? Yes, you are right, 68．Now please write the number under 34．Continue until you have a number on the same line as 1．Now draw a line through any row that has an even number on the left．Yes, even number means 偶數(shù) in Chinese．In our example there is only one even number．Right? Now please draw a line through the line that has au even number on the left．Now add the rest of the numbers in the right hand row．Believe it or not, you will get the right answer．What is it? OK．Please write the number, I mean the right answer in the right place．

Now class, I'll give you several minutes to discuss how it works．

閱讀下面對(duì)話，從方框中選擇五個(gè)最適當(dāng)?shù)木渥油瓿蓪?duì)話（其中有2個(gè)選項(xiàng)是多余的）。

Li Yang: Good morning, Mathew.

Mathew:  Good morning, Li Yang. 1.

Li Yang: There's still smog（霧霾）today. We'll have to go to school with face masks（口罩）．

Mathew:2.         According to the news, PM2.5 pollution is the main problem  with air pollution.

LiYang:  Yes, and air pollution has done harm to people's health.

Mathew:  So the Chinese government and Chinese people must take action to fight it.

Ji Yang:3.

Mathew:  Since PM2.5 is mainly caused by vehicles（機(jī)動(dòng)車）and factories, cars with large emissions（排放）should not be allowed and factories should be closely watched.

LiYang:4.        We hope that more and more people will join us in making the blue skies return for good.

Mathew:5.
