Would you please ________ in class?

[　　]

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 偶数 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．

How to talk to a foreigner? Students often want to practice their English outside class．One of the best ways to practice your English is to speak to a foreigner．This week's question comes from a student who is eager to start a conversation with the foreigners he sees every day．He asks, “Is it okay to talk to foreigners I see in the street? The answer is yes and no, but probably no．If you see a foreigner who looks lost，it is polite to ask him。”May I help you? But，otherwise（除此之外），you should probably let him get on with his business．Situations，however, do exist where it is quite all right to talk to foreigners．If a foreigner enters year school，classroom，office，shop or restaurant，for instance，feel free to ask them  （for example）：

--May I know your name，please?

--Where do you come from?

--What do you think of Beijing?

--How long will you stay in Beijing?

There are also situations where it's okay to talk to foreigners in public places．If you see a foreigner alone in a restaurant，bar or care, it may be appropriate（恰当的）to ask him or her：

--Is this seat free?

--Do you mind if I talk to you in English?

--You pan probably help them if they are new to China and if they are alone，you may be able to make them feel more welcome．After a few such questions, you should know whether this person wants to talk to you or not．If they ask you similar questions, or if they give long, informative（提供有用信息的）answers, you're in luck．If not，then give them their privacy（独处）．Talking to strangers is fun if you choose the right time and place．
