例证指具体说明人或事物特点、本质及其规律的方法。所用例子需有代表性、典型性。例证型段落的写作方式多为先提出主题再列举事例。在事例之前一般有For example或For instance。例证后面，根据情况还可以加上结论句。如：
In order to prevent non-smokers from being affected, measures must be taken to reduce the chances of smoking. A lot of work can be done concerning this. For example, in some public places, such as in the theatres and cinemas, smoking should be forbidden. Even on the train or plane people should not be allowed to smoke. Doctors, teachers and government leaders should take the lead not to smoke. Above all, the harmfulness and dangers caused by smoking should be made known to all through newspapers, broadcast, or TV programs. Also the growing of tobacco and the production of cigarettes should not be encouraged. If these measures can be taken, we can effectively reduce the chances of smoking.

因果是两个事物之间的关系。一些说明文，议论文通过分析因果关系说明一个中心思想。如不能把因果关系解释清楚，文章将无法说明任何主题。
因果型段落的扩展模式有两种，一是分类编法，另一个是连环编排法。如果只讨论成因或只讨论结果，细节比较简单，只需按其重要性或其逻辑顺序进行编排。分类编排法指先讨论原因，然后讨论结果;或先讨论结果，后讨论原因。
1)分类编排法：
Music is my chief hobby. When I listen to music, good things happen to me. If I am lonely or homesick, I listen to pop music. The quick rhythm, the strong beats of drums lift my sprits. If I am familiar with a song, I will sing alone with it and my depression disappears. When I am bored or very tired, I listen to Mozart. His music makes me feel alive. Music also reminds me of home. Before I came to college, my sisters and I would listen to music and sing songs together and cheer us. Now I enjoy listening to music and singing with my roommates because their smiles make me remember the happy times with my family. For me, music is an excellent escape, and without it, I wouldn’t be so happy.
2) 连环编排法是先讨论一组因果，再一组因果，再一组因果，形成一个锁链。当因果紧密相连，前一果为后一果之因时，经常使用这种方式。
Students shouldn’t stay up so late. Because of the pressure of examinations, many students burn night candles. The next day, they have to get enough sleep. As a result, many of them get sleepy in class. They couldn’t catch what the teacher says. Not having studied their lessons well, they find it difficult to make good performance in examinations. So, it is not worthwhile to stay up late if you want to study well.

人物描写包括外部特征、性格特征、思想状态、行为语言等，用于表现人物精神面貌、披露人物内心活动、揭示人物性格变化，借以突出作品主题思想。如：
My sister is a boyish girl. She has short and straight hair like a boy’s. She likes white, black and grey colors, as most boys do. She never cares for shirts, stockings but loves jackets and jeans. Sometimes she wears a men’s suit and leather shores as if she were a gentleman. Basketball and football are her favorite sports. She also enjoys watching boxing. She always shouts and cheers excitedly when she is watching a football match. When she is with her friends, she always says Ladies first” to other girls. The most interesting thing is that she has been mistaken for a boy many times. And she is pleased with that. She always says that she should be a boy.

今天早上，我突然间发现我家的房顶上有一个燕子窝，我高兴极了，想上去把它弄下来，但是呢，我看到里面有许许多多的小燕子。但是呢，燕子妈妈在哪儿呢?哦，原来燕子妈妈去给他们找吃的了。
我津津有味的坐在门檐上看着那些小燕子，终于燕子妈妈回来了。燕子妈妈的嘴里叼着几条小虫子，那些小燕子似乎感受到妈妈回来了就叽叽喳喳的叫个不停。燕子妈妈回到窝里面，那些小燕子一个个张着嘴巴在等燕子妈妈喂食物，燕子妈妈把嘴里的小虫子给他的小燕子一一分开。
看着这暖心的一幕，我不心想到了自己小时候。想着小时候妈妈是不是也是这样给我喂食物呢?于是我就去问妈妈，妈妈说：“是的呀，小时候你可调皮了，让你吃饭你都不吃。”我哈哈大笑说：“原来我小时候是这样的调皮呀。”
俗话说：“父爱如山，母爱如河”这次我才真正的感受到了什么是母爱如河。

比较对照有两种，一是逐点比较，二是整块比较，即AB交错或先A后B：
1)逐点比较：多数人认为这种AB交错的方式可以避免行文的单调沉闷，对比的效果更鲜明突出。如：
There are basic differences between large and small enterprises. In a small enterprise, you operated mainly through personal contacts. In a large enterprise, you have established “policies” , “channels” of organization, and fairly strict procedure. In the small enterprise you have immediate effectiveness in a very small area. You can see the effect of your work and of your decisions ground. In the large organization you are normally taught one thing thoroughly. In the small one the danger is of becoming a Jack-of-all-trades-but-master-of-none. In the large it is of becoming the man who knows more and more about less and less.
2) 整块比较
It is easy to be a winner. A winner can show his joy publicly. He can laugh and sing and dance and celebrate his victory. People love to be with winners. Winners are never lonely. Unlike winners, losers are the lonely ones of the world. It is difficult to face defeat with dignity. Losers can not show their disappointment publicly. They can not cry or grieve about their defeat. They may suffer privately, but they must be composed in public. They have nothing to celebrate and no one to share their sadness.

每年放假，我总会去乡下老家玩。去年寒假，我去的是外婆家。
除夕那天，我醒的很早。我以为年夜饭从早上就开始准备了，想去帮外婆他们的忙，可是一直等到下午，大家才开始忙碌起来。
外婆刚在厨房烧起了火准备做年饭，姨夫、哥哥和姐姐就开始摆桌子和椅子了。我也过去帮忙。我们在院子里摆了三张大圆桌，每张桌子上都有一大瓶饮料和酒。这时，二姨来了。她跟我们打了个招呼就到厨房里帮外婆做年饭了。过了一会儿，像是约好了似的，一群人一个接一个地来了。他们之中有小孩，有大人，也有老人。他们互相乐呵呵地打招呼，嘘寒问暖，仿佛是八辈子的老朋友。
夜幕降临时，菜端上桌来了。人们拉开一把把椅子，在各自的杯子里倒上酒和饮料。当菜全部端上后，人们开始互相敬酒，真诚地祝福对方在新的一年里有个好运气。在那一瞬间，所有人都安静下来了，只剩下碰杯时叮叮当当的声音和把饮料和酒一饮而尽的声音。
终于开始吃年饭了，气氛又热闹起来。人们拿起筷子，夹起一道又一道的菜，津津有味地吃着。小孩子们像几天没吃饭似的，狼吞虎咽地吃着，拼命往嘴里塞东西。不时有人来敬酒，所以经常能看到站起身碰杯的人。
很快，年饭就吃完了。姐姐拿出烟花，用火点燃了导火索。随后，伴着一阵阵巨大的响声，烟花开始燃放了，在人们的赞叹声中点亮了漆黑的夜空，绽放出美丽的花朵。
烟花放完了，人们也回家了，我便开始守岁。我捧着一本书看着，但满脑子里想的都是吃年饭时的情景。不知不觉中过了十二点，除夕悄无声息地溜走了。

The first thing I notice in the bride’s room is the beautiful curtain. This curtain is patchwork in design, and is sewn out of squares of materials of different colors like white, light green, brown and orange. It is made of silk, trimmed with delicate braids. It is about six feet long and hangs from a wooden rail. The curtain matches perfectly with the dark wooden rail and furniture in the room.
