很多人都不知道怎么写作文的主题句，下面是小编分享的一些关于雅思写作如何写主题句的文章，欢迎阅读!
一、雅思写作如何写主题句
雅思大作文四个评分标准的第一个就是Task Response(任务回应情况，以下简称TR)，即，切题。众所周知，雅思大作文题目都是由题干和写作要求(疑问句或者陈述句)组成的，比如：题目1
Some people think that governments should invest more in teaching science.
Do you think the advantages outweigh its disadvantages?
显然，为了切题，题干和写作要求都应该在文章主题句中体现出来。否则，写出的主体段就会出现放在哪个题目下都合适的尴尬局面：轻者考官认为偏题，重者考官则可能判为模版，分数可想而知。
二、关键词
“关键词”是题干中能体现出题意图的词或短语，一个核心焦点，即单边，就有一组“关键词”，如果题干是双边，则用两组“关键词”表示题干。那么如何准确定位关键词呢?毫无疑问，找关键词的前提是读懂题干意思，既然能够代表题干主旨、出题意图，那么在确定关键词之后，假设关键词是“A”，就可以问自己：“这个题目问的是A的原因吗”、“这个题目问的是A的优缺点吗?”等。比如：
Because of traffic and housing problems in the cities, the government encourages business to move to the rural areas.
Do you think the advantages outweigh the disadvantages?
关键词如果是“traffic and housing problems”的话，那就可以问：“这个题目问的是：原因是交通和住房问题还是其它的吗”，显然不是，同样方法找出关键词是“business move to the rural areas”。
三、最终原因/结果
综合所有题目中的“写作要求”，雅思大作文本质是写出“关键词”的“原因”、“影响”或“解决措施”。不难理解，在找出题干“关键词”后，如果问原因，那么以“关键词”为起点，需要往前推理，得出“最终原因”;如果问“影响”，那么以“关键词”为起始点往后推理得出“最终结果”;如果问“措施”，则在推出原因后，提出相对应的解决措施即可。
invest in teaching science(理科)——>理科科目(subjects)就会增加/学习理科科目的人数就会增加——>理科相关科目从业者(practitioners)就会增加——>促进国家相关行业发展
那么，以“关键词”为起点的思路就写出来了，那么这个题目中的“最终结果”就是：“促进国家相关行业发展”。另外，需要注意的是此过程中箭头右边务必是箭头左边的最直接结果，否则，在论证过程中会出现逻辑漏洞。
然后，要确保“关键词”和“最终结果”都出现在文章中，该论点的主题句就可以写成：
If government funding is invested heavily in science, the corresponding sectors of a country would be improved a lot.
Many people these days work in other countries, taking their family with them.
Do you think the advantages outweigh its disadvantages?
take family with them——>工作时分心(be distracted)——>工作表现不好(poor performance of their duties)——>令老板失望(be disappointed)
根据“关键词”+“最终结果”，该题目的主题句是：带家人出国工作令其老板失望(The decision to move to another country with their family can make the bosses be disappointed)。不难看出，这样的主题句仍然会使读者困惑，达不到段落主题句应有的效果，因为从关键词直接跨到最终结果跨度太大。
这时可以将中间步骤放在“关键词”+“最终结果”之间，改成：“关键词”+某个“中间步骤”+“最终结果”，那么该题目的主题句可以写成：
The decision to move to another country with their family may be highly likely to distract those managers from work, which would make the bosses be disappointed.
主题句关系到主体段落的论证过程是否切题，更关系到考官对于整篇文章内容的定位，相信读者也已经意识到了段落开头句的重要性。希望考生勤加练习，最终可以写出准确恰当的主题句。
四、雅思写作主题句写作方法详细讲解
众所周知，雅思大作文题目都是由题干和写作要求(疑问句或者陈述句)组成的，比如：
题目1
Some people think that governments should invest more in teaching science.
Do you think the advantages outweigh its disadvantages?
题目2
Some people prefer to do a stable job, while others suppose that changing jobs is good for young people.
Discuss both views and give your own opinion.
显然，为了切题，题干和写作要求都应该在文章主题句中体现出来。否则，写出的主体段就会出现放在哪个题目下都合适的尴尬局面：轻者考官认为偏题，重者考官则可能判为模版，分数可想而知。那么，如何使题目关键信息都集中在主题句中呢?这就需要两个概念：“关键词”和“最终结果/原因”。
关键词
比如题目1，很明显，该题目“关键词”就是“invest in teaching science”，然而有的题目则没有这么明显，这时就可以通过以上方法找出关键词。
比如
Because of traffic and housing problems in the cities, the government encourages business to move to the rural areas.
Do you think the advantages outweigh the disadvantages?
关键词如果是“traffic and housing problems”的话，那就可以问：“这个题目问的是：原因是交通和住房问题还是其它的吗”，显然不是，同样方法找出关键词是“business move to the rural areas”。
最终原因/结果
invest in teaching science(理科)——>理科科目(subjects)就会增加/学习理科科目的人数就会增加——>理科相关科目从业者(practitioners)就会增加——>促进国家相关行业发展
那么，以“关键词”为起点的思路就写出来了，那么这个题目中的“最终结果”就是：“促进国家相关行业发展”。另外，需要注意的是此过程中箭头右边务必是箭头左边的最直接结果，否则，在论证过程中会出现逻辑漏洞。
然后，要确保“关键词”和“最终结果”都出现在文章中，该论点的主题句就可以写成：
If government funding is invested heavily in science, the corresponding sectors of a country would be improved a lot.
Many people these days work in other countries, taking their family with them.
Do you think the advantages outweigh its disadvantages?
take family with them——>工作时分心(be distracted)——>工作表现不好(poor performance of their duties)——>令老板失望(be disappointed)
根据“关键词”+“最终结果”，该题目的主题句是：带家人出国工作令其老板失望(The decision to move to another country with their family can make the bosses be disappointed)。不难看出，这样的主题句仍然会使读者困惑，达不到段落主题句应有的效果，因为从关键词直接跨到最终结果跨度太大。
The decision to move to another country with their family may be highly likely to distract those managers from work, which would make the bosses be disappointed.
除此之外，段落与段落之间如果存在逻辑关系，还可以加上相应的表示转折关系、递进关系、并列关系等的连接词，以加强段落之间的逻辑关系。
二、雅思写作如何写主题句
1、通过比较和对比方式来论证，这样两个事物、行为或者观点的利弊就非常明显。
Those who believe in the measure say that students benefit a lot fromtraveling or working for a year before their formal university education. First,they can more broadly acquainted themselves with the society, deepen theirunderstanding of the outside world, and thus better coordinate their objectivesof learning with the needs of the society.
In contrast, by immediate entrance to university they can not steer thedirection of their study well and may display a poor combination of the theorywith practice. Second, study at high school is really exhausting, especiallywhen to win college admission. So it is necessary to grant these children arelatively long period of relaxation or buffer, say, traveling or working for ayear, to loosen the chords of their brain, so that when they go back to schoollater again, they can become completely refreshed and rejuvenated.
这篇雅思大作文写作的内容是关于上大学前是否应该用一年的时间来旅游或者工作进行论证。此段的主题是学生在进入大学学习之前花一年时间进行旅游或工作的话，会让他们受益匪浅。
对比点是：进入大学之前一年进行旅游或工作有利于让学生广泛了解社会，加深他们对外界的理解，因此能让他们更好地协调好学习目标和社会的需要。应用这样的雅思大作文写作方法，相对比之下，直接进入大学学习的话，他们不能够把握学习的方向，而且有可能会产生理论和实践相脱节。通过此番对比，旅游或工作一年对于即将步入大学的学生们的好处是显而易见，段落的主题句得到有力的论证。
2、通过假设进行正反论述
Then, since the transportation system is the lifeline of a country’seconomic activities, its paralysis would lead to the disintegration of theeconomy, either industry of farming or daylife. Suppose all the means oftransportation were halted for lack of oil, factories with insufficient rawmaterials would have to close, workers would be out of work, and ripe farm cropswould have to stay in the fields at the mercy of rain and storms. People wouldtry to store food and the price of all commodities would go up. If we take thosepower stations run by oil into account, situations would become even worse. Inthis sense, oil decides the fate of the whole economy and that of thegovernment.
通过假设得出了一系列的可怕的后果，最后再得出结论，这样的结论是发人深省，当然也是最能引起人们广泛重视的，这样的雅思大作文写作方法是最容易给人留下深刻印象的。
