雅思写作逻辑训练之常见的句子结构问题

雅思写作想要拿高分，句子机构这种小错误是不能犯的。例如英文两个独立的句子(independent sentence)，是不能使用逗号链接的，有时候可能我们会把中文的习惯带到雅思写作中去，逗号不是连词，可以用分号或者句号连接。下边新航道老师给大家总结一些常见的问题。

副词(therefore, thus, however )或者是连接的表达(as a consequence, as a result, because of this, in addition, for example, in contrast)等都不是连词

Children from poor families cannot receive education, therefore, they are more likely to violate the law.

错误的原因：therefore 是副词，不是连词，需要前面加上句号或者是分号，或者改成连词so

正确的句子：Children from poor families cannot receive education; therefore, they are more likely to violate the law.

正确的句子：Children from poor families cannot receive education, so they are more likely to violate the law.

从属连词while, because, as,一定要连接两个完整的句子，不能够只是连接一个句子。

Young people are more willing to adopt advanced technology. Because they want to find jobs in the hi-tech industry.

错误的原因：because 是连词，一定要连接两个句子。

正确的句子：Young people are more willing to adopt advanced technology, because they want to find jobs in the hi-tech industry.

介词 (because of， due to, despite, in spite of, of 等)不是连词

The proportion of people who went to the cinema decreased.

The proportion of people decreased.

The proportion of people going to the cinema decreased.

句子一般不可能连续出现两个动词，在没有连词或者是从句的情况下

There was a river crossed the area from north to south.

错误的原因：一个句子两个动词was, crossed。要么“which crossed”，要么就是“crossing”

正确的句子：There was a river which crossed the area from north to south.

This causes global temperatures rise.

错误的原因：一个句子两个动词cause 和rise. 要说“to rise ”不定式充当补语

正确的句子：This causes global temperatures to rise.

除了句号和分号外，用连词and 或者是从属连词because, if 等去连接也是正常的方法。

有时候，会用定语从句联系两个句子。

This is particulary the case for younger generation, they may lose confidence in the future life.

错误的原因：两个独立的句子没有连词，They 改成who，变成定语从句

正确的句子：This is particulary the case for younger generation, who may lose confidence in the future life.

状语从句主句和从句都必须是独立的句子

When come to school age, most children spend most of the day in their school with their teachers and classmates.

错误的原因：when 后面要跟完整的句子，when they start school

正确的句子：When they start school, most children spend most of the day at school with their teachers and classmates.
