便笺写作（Note Writing）实际上与书信写作（Letter Writing）大致相似，但有三点主要不同：

1. 便笺较随便，因此语气通常更轻松，格式和语言都是如此。2. 通常便笺较短，应言简意赅，这意味着你必须略去冗余信息。3. 便笺写起来往往更具个性化，通常语言更接近口语，更直接。

Directions:

Dear Jane,

I have a big favor to ask you. I am late for my appointment with Professor Jones, and need to go directly to his office. I also have two books that are due back at the library this evening. As I will not be able to get to the library before it closes, I was wondering if you would possibly have the time to return the books for me.?

I realize this is a big favor to ask of you, as you are also very busy. In return for help, I would like to buy you lunch tomorrow. Thanks in advance!

It has been shown that children who smoke have certain characteristics. Compared with non-smokers they are more rebellious, their work becomes worse as they move up school, they are more likely to leave school early, and are more often delinquent (轻微犯罪) and sexually premature. Many of these features can be summarized as anticipation of adulthood.

There are a number of factors which determine the onset of smoking, and these are largely psychological and social. They include availability of cigarettes, curiosity, rebelliousness, appearing tough, anticipation of adulthood, social confidence, the example of parents and teachers, and smoking by friends and older brothers and sisters.

It should be much easier to prevent children from starting to smoke than to persuade adults to give up the habit once established, but in fact this has proved very difficult. The example set up by people in authority, especially parents, health care workers, and teachers, is of prime importance. School rules should forbid smoking by children on the premises. This rule has been introduced at Summerhill School where I spent my school days.

There is, however, a risk of children smoking just to rebel against the rules, and even in those schools which have tried to enforce no smoking by physical punishment
