【写作指导】

1. 事理说明文

介绍如何做某事的说明文属于事理说明文，比如说明如何使用某件新产品、如何做某种食物、如何保持身体健康等。写这类说明文应注意以下几点：

（1）说明顺序要合理。因为事理说明文是阐述事理的，所以多采用逻辑顺序。常见的几种逻辑顺序包括：从因到果、从主到次、从整体到部分、从概括到具体、从现象到本质、从具体到一般等。

（2）说明方法要灵活。常用的方法包括下定义、举例子、列数字、引用、比较、分类等。

（3）说明知识要准确。

2. 事物说明文

介绍事物特点的说明文属于事物说明文，其说明对象是具体事物，目的是使读者了解该事物。

（1）介绍产品时，可以从其外形、颜色和功能等方面进行说明。在说明过程中，可【我爱线报网】借助细节描述法使被介绍的内容清晰丰满。

（2）介绍建筑物时，首先要点明它的功用，然后按照空间顺序或参观的顺序来介绍。

A

My Approach to Difficulties in Learning

As high school students, we run into one difficulty after another in the process of learning. Everyone has their own way to deal with them. Here I would like to share mine.

When I am faced with a difficulty, I usually choose to refer to rele【我爱线报网】vant learning materials or Web pages. In this way, I can not only work it out but also improve my ability to overcome problems all by myself.

However, when it is something beyond my competence, I turn to my classmates or teachers for help. Sometimes I also ask my parents for advice. As a result, I ha【我爱线报网】ve made steady progress in my studies.

As for its functions, not only can the technique be used to predict major diseases, but it a【我爱线报网】lso enables people to see the examinees food preferences. With such a technique, examiners are able to provide various suggestions on appropriate exercise for examinees. It is said that the test will enhance the examinees consciousness of health, but on the other hand it will also be likely to cause【我爱线报网】 over-anxiety.

My Magic Shoes

To make our life easier and the environment more beautiful, I have designed a pair of magic shoes. Compared to the traditional ones, they have three new unique functions.

1. The shoes are made from specially produced recycled paper which can stand high pressure and temper【我爱线报网】ature and will never wear out.

2. Theres no need for you to wash them, for they wash themselves.

3. Most magically, they can be used as a means of transportation. When you want to get somewhere quickly, they will speed up by themselves and you will have a sense of flying. Because of these shoes, in th【我爱线报网】e future fewer and fewer people will drive cars. In this way our world will be greener and cleaner.
