所谓三段式就是将一篇书面表达按三段的写作模式谋篇布局。三段式的模式写法通常为：
1．第一段开门见山，提出要解决的问题或观点，或者把时间、地点、人物和主要事情及时点出。
2．第二段要摆出事实或提出论据，或者把事情发展的经过详细写出来。
3．最后一段，得出结论或理由。
注意：要学会使用过渡词。过渡词犹如“桥梁”和“粘合剂”。恰当地使用过渡词可避免结构松散，层次不明，表意不清等弊端，使文章条理清楚，文字连贯流畅。常用的过渡词有：
递进型：besides，what’s more，let alone，worse still，moreover，even，furthermore等；
解释型：that is (to say)，in other words，or等；
转折型：however，but，yet，although，otherwise，instead，on the contrary等；
列举型：firstly...secondly...finally，on the one hand，on the other hand等；
举例型：for example，for instance，such as，that is，like，take...for example等；
因果型：because (of)，since，therefore，as a result，thanks to，thus，due to等；
让步型：though，although，in spite of，despite等；
顺序型：first...next...and then...finally，first...then...after that...finally等；
并列型：and，or，also，as well as等；
时间型：afterwards，soon，later，the moment，hardly...when...，no sooner...than...等；
总结型：in conclusion，in a word，to sum up，in short，on the whole等；
见解型：in my opinion，personally speaking，as far as I am concerned等。
以上写作模式可时常运用于实际的写作过程中，只要我们把握好写作技巧和模式，书面表达能力的提高也就指日可待了。

I’m so pleased to learn that you and your classmates are learning Chinese.
I’d like to recommend the following two dictionaries.The English－Chinese Dictionary is really a good one for beginners.It has 18,000 English words and 20,000 Chinese words.Besides plenty of examples，it has many notes telling you how to use a word.Xinhua Dictionary is the most popular Chinese dictionary，and it has a vocabulary of 10,000 words.It may also be useful to some advanced learners of Chinese.Of the two，ECD is more expensive.It costs 52 yuan，and XD costs 11 yuan.
Please let me know if you want me to buy one for you.

【参考答案】
Is a Training Class or Family Teacher Necessary?
More and more middle school students are going to all kinds of training classes or having family teachers at weekends.There are two different viewpoints about it.
Some think it necessary.First of all，it’s more effective to study with a teacher than by themselves.Secondly，it can strengthen what they have learnt in class.Besides，they can learn a lot more.Others think it unnecessary.For one thing，students can easily form the habit of dependence.For another，students need time to relax from time to time.What’s more，the purpose of many training classes and family teachers is to make money.
In my opinion，whether a training class or family teacher is needed just depends.Do be sure to choose a good and suitable class or teacher，otherwise it would be a waste of time and money.
