(I)说明原因型模块 Currently, XX has been the order of the day. This does demonstrate the theory --- nothing is more valuable than XX It is clear that (1). If you (2), as a result, your dreams will come true. On the contrary, if you (3). Failure will be following with you. It turns out that all your plan falls through. No one can deny another fact that (4).You don't have to look very far to find out the truth, in respect that we all know (5).It will exert a profound influence upon (6).With reference to my standpoint, I think (7). 注释: 1:XX的第一个优点 2:支持XX的做法 3:不支持XX的做法 4:XX的第二个优点 5:举例证明优点二 6:说明XX优点三的影响第三天我写的相应作文: The importance of self-confidence Currently, self-confidence has been the order of the day. This does demonstrate the theory --- nothing is more valuable than self-confidence. It is clear that (self-confidence means trust in one's abilities). If you (are full of self-confidence, it will bring your creative power to play, arouse your enthusiasm for work, and help you overcome difficulties), as a result, your dreams will come true. On the contrary, if you (have no confidence in yourself, there is little possibility that you would ever achieve anything ). Failure will be following with you。It turns out that all your plan falls through. No one can deny another fact that (self-confidence gives you light when you are in dark and encouragement when you are dismayed).You don't have to look very far to find out the truth, in respect that we all know (the secret of MMe. Curie lies in perseverance and self-confidence, the latter in particular). It will exert a profound influence upon (the achievement of one's ambitions). With reference to my standpoint, I think (he that can have self-confidence can have what he will). (I)说明原因型模块(2) In recent years, XX has caused a heated debate on (1). The factors for (2).First of all, (3).Then, there comes a case that (4). Moreover, (5). Especially when (6).Indeed, these unique points can be collected the remind people that (7).In this way, we should behave just like (8). The impact of Television In recent years, with the development of science and technology, 80 percent of all homes in China have satellite TV, offering as many as 50 channels. It has caused a heated debate on (the impact of television on children). Many parents are worried about the impact of so much television on children. The factors for (parents' worry is that children are indulge in television and spend too much time on it.).First of all, (with so many programs to choose from, children are not getting as much exercise as they should ).Then, there comes a case that (some studies have show that excessive watching of television by millions of children has lowered their ability to achieve in school ). Moreover, (the effect on children's minds are more serious than the effect on children's bodies). Especially when (the children are too small to judge what programs are suit to them).Indeed, these unique points can be connected to remind parents that (they should pay close attention to and responsibilities for supervising their children's TV viewing).In this way, children will not be influenced too deeply. (I)说明原因型模块(4) For most of us today, (1). From above, we can find that the reasons why (2)are as follows. The primary reason, I think, is (3).Second,(4). The third reason, actually, is (5).The significance for (6)。 Therefore, (7). 注释: (1)人们针对XX的态度和举措 (2)归纳现状 (3)第一个原因 (4)第二个原因 (5)第三个原因 (6)重申造成现状的最重要原因 Pollution Most of us today (recognize that environmental pollution has been a greatly serious problem. lots of plants trees corps are destroyed by bad air. many fish die of poisonous water. thousands of people die from eating poisoned fish or breathing in gas. therefore, environmental pollution should be responsible for these diseases that are disabling, or bringing death not only to human beings, but also to wild life.)From above, we can find that the reasons why (environment are polluted more and more seriously)are as follows. the primary reason, I think, is (the reason of harmful substances into environment. for example, to prevent insects, farmers make use of great amounts of insecticides, so as to have bumper harvests. however, they pollute air, water and land ). Second,(the gas coming from the car engines and factories also make environment polluted badly ). the third reason actually is (the result of a growing population in the world. everyday, so much litter and waste are poured out from houses, also pollute the environment ). The significance for (controlling pollution) noted that it's high time that more effective measures should be taken. Therefore, (new laws should be passed to limit the amount of pollutants from factories. moreover, in the households, there is an obvious need to reduce litter and waste. let's make our good efforts, and the world will be a safer place to live for us). (I)说明原因型模块(5) These days we often hear that (1).It is common that (2). Why does such circumstance occur in spite of social protects? For one thing, (3).For another, (4). What is more, since (5),it is natural that (6 ).To solve the problem is not easy at all, but is worth trying. We should do something such as (7) to improve he present situation, and I do believe everything will be better in the future. [详细信息] (1)提出论题 (2)说明现状 (3)理由一 (4)理由二 (5)理由三 (6)理由三引起的后果 (7)解决方法 Pollution of environment These days we often hear that (our living conditions are getting more and more serious because of the destruction of our environment ).It is common that (many trees and animals are near extinction, and the all-important food chain has been destroyed.). Why does such circumstance occur in spite of social protects? For one thing, (the population of the world is increasing so rapidly that the world has been so crowded. ).For another,(the overuse of natural resources has influenced the balance of natural ecology ). What is more, since (the industrial revolution ),it is natural that (a great number of factories have been springing up like mushrooms. The smoke and harmful chemicals released from factories also pollute the environment). To solve the problem is not easy at all, but is worthing. We should do something such as (planting more trees, equipping cars with pollution-control devices and learning to recycling natural resources )to improve the present situation, and I do believe everything will be better in the future. 写作模板——图表式作文 It is obvious in the graphic/table that the rate/number/amount of Y has undergone dramatic changes.

It's no easy task to find a satisfactory answer to the issue. As for me, there's some truth to both arguments .It's advisable to ______.

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

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

我是一名英语过了大学六级的学生，英语作文只用模板写是不行的，分享一些方法你参考一下吧英语的学习方法如下我们来看看英语是由什么组成的。1 字母，2读音，3单词，4语法一一进行解释。1. 26个字母是组成单词的基本要素之一。2. 48个音标是单词读音的基本要素之二。 3.上面两个搞定后，就剩下单词与语法了。我们来假设一下，看看哪个更是句子的核心。假设1：如果你对语法不理解，单单靠记忆单词学英语。就会有：give you color to see see（给点颜色你看看）完全是中式英语，外国人是看不懂的。假设2：如果你理解语法。就会有：Because you waited too long to make your move, and now you're in the friend zone. (因为你拖太久才行动，现在只能待在”朋友区”)你就会知道，英语是先做完一个动作再接着做一个动作（以动词为依据）。上面句子第一个动作(动词为wait)：you waited too long（你等待得太久）第二个动作(动词为make)：to make your move(去行动) to是用来隔开两个动作。第三个动作(动词为are)： you're in the friend zone（你待在”朋友区”）。4.总结显示，我们中国人学英语是缺少一个语感，我们的生活圈子中没有这样的英语交流环境，只能以语法去理解英语句子中的单词排版规律了（通俗地说就是单词在句子中的位置）还有网上的东西让人眼花缭乱，我觉得“英语年华的空间”里面的日志还是不错的，让我受益非浅。我没有过英语六级之前，天天都泡在他的日志里面学习，获得了很多书本上没有见过的英语知识，确实值得英语学习者借鉴学习。“英语年华的空间”。百度一下就可以看到在页面上的第一条了。5.关于尾声学英语靠的是坚持，不能三天打鱼两天晒网，只要坚持就会看到希望。如果不坚持，一辈子（100年）都学不会，如果坚持，半年后的英语就已经很厉害了。加油，祝你成功！
