在四六级考试中，好的作文无异于锦上添花，那么怎样才能写好作文呢，下面给大家分享几个不同题型的英语四级作文万能模板：

一、英语四级作文万能模板

解决方法型

1. 问题现状

2. 怎样解决(解决方案的优缺点)

In recent days, we have to face I problem-----A, which is becoming more and more serious. First, ------------(说明A的现状).Second, ---------------(举例进一步说明现状)

Confronted with A, we should take a series of effective measures to cope with the situation. For one thing, ---------------(解决方法一). For another -------------(解决方法二). Finally, --------------(解决方法三).

Personally, I believe that -------------(我的解决方法). Consequently, I’m confident that a bright future is awaiting us because --------------(带来的好处).

对比选择型

When it comes to ____ ,different people hold different views .

Some contend that____. For one thing,____ .For another,___ . In spite of all these claims, others maintain that ____，They point out that____ .Another instance often cited is that____ .

说明利弊题型

说明利弊这种题型往往要求先说明一下现状，再对比事物本身的利弊，有时也会单从一个角度(利或弊)出发，最后往往要求考生表明自己的态度(或对事物前景提出预测)

1. 说明事物现状

2. 事物本身的优缺点(或一方面)

3. 你对现状(或前景)的看法

Nowadays many people prefer A because it has a significant role in our daily life. Generally, its advantages can be seen as follows. First ----------------(A的优点之一). Besides -------------------(A的优点之二).

But every coin has two sides. The negative aspects are also apparent. One of the important disadvantages is that ----------------(A的第一个缺点).To make matters worse,------------------(A的第二个缺点).

Through the above analysis, I believe that the positive aspects overweigh the negative ones. Therefore, I would like to ---------------(我的看法).

(From the comparison between these positive and negative effects of A, we should take it reasonably and do it according to the circumstances we are in. Only by this way, ---------------(对前景的预测).)

阐述主题题型

1.阐述名言或主题所蕴涵的意义。

2.分析并举例使其更充实。

The good old proverb ----------------(名言或谚语)reminds us that ----------------(释义). Indeed, we can learn many things form it.

In my opinion, ----------------(我的观点). In short, whatever you do, please remember the say------A. If you understand it and apply it to your study or work, you”ll necessarily benefit a lot from it. From .

二、使用方法

1.看到一个作文题，先思考一下你会怎么写，从哪些角度，用什么句式。2.然后再在草稿纸上列个简单的提纲。3.再根据模板，按照自己的提纲，把模板往提纲里套。4.写完修改后，完善这篇作文，提取出适合你的思考逻辑的模板5.先记住中文译文的行文思路，再背诵英文模板。

平时一定要注重积累，写作文的时候套用上面的万能模板多练习，作文的逻辑和句式都是通用的，同时也要多背诵一些例句，不至于考试的时候想不起来！

排放冷却是对流冷却的另一种。与再生冷却不同，用于排放冷却的冷却剂对推力室冷却吸热后不进入燃烧室参与燃烧，而是排放出去。直接排放冷却剂会降低推力室比冲，因此需要尽可能减少用于排放冷却的冷却剂流量，同时只在受热相对不严重的喷管出口段采用排放冷却。还有一种是辐射冷却，其热流由燃烧产物传给推力室，再由推力室室壁想周围空间辐射散热。辐射冷却的特点是简单、结构质量小。主要应用于大喷管的延伸段和采用耐高温材料的小推力发动机推力室。在组织推力室内冷却时，是通过在推力室内壁表面建立温度相对较低的液体或气体保护层，以减少传给推力室室壁的热流，降低壁面温度，实现冷却。内冷却主要分为头部组织的内冷却（屏蔽冷却）、膜冷却和发汗冷却三种方法。推力室采用内冷却措施后，由于需要降低保护层的温度，所以燃烧室壁面附近的混合比不同于中心区域的最佳混合比（多数情况下采用富燃料的近壁层），造成混合比沿燃烧室横截面分布不均匀，使燃烧效率有一定程度的降低。膜冷却与屏蔽冷却类似，是通过在内壁面附近建立均匀、稳定的冷却液膜或气膜保护层，对推力室内壁进行冷却，只是用于建立保护层的冷却剂不是喷注器喷入的，而是通过专门的冷却带供入。冷却带一般布置在燃烧室或喷管收敛段的一个横截面上。沿燃烧室长度方向上可以有若干条冷却带。为提高膜的稳定性，冷却剂常常经各冷却带上的缝隙或小孔流入采用发汗冷却时，推力室内壁或部分内壁由多孔材料制成，其孔径为数十微米。多孔材料通常用金属粉末烧结而成，或用金属网压制而成。此情况下，尽可能使材料中的微孔分布均匀，是单位面积上的孔数增多。液体冷却剂渗入内壁，建立起保护膜，使传给壁的热流密度下降。当用于发汗冷却的液体冷却剂流量高于某一临界值，在推力室内壁附近形成的是液膜。当冷却剂流量低于临界值流量时，内壁温度会高于当前压力下的冷却剂沸点，部分或全部冷却剂蒸发，形成气膜。除了以上热防护外，还有其他热防护方法如：烧蚀冷却、隔热冷却、热熔式冷却以及室壁的复合防护等。3 高焓气体发生器热防护方案综合上述方法结合实际情况，便得到高焓气体发生器的热防护方法。高焓气体发生器的燃烧室与液体火箭发动机的不同，省去前面的推力室部分，使得其结构更简单而有效。那么，所涉及到的热防护即为对燃烧室室壁的热防护部分。由于燃料进入燃烧室内迅速分解并放出大量
