特别注意Exceptions:quite a few people,to a certain extent/degree
六、标点符号（主要是逗号）的使用Use of Commas
在雅思写作中，我们经常会用“语段连接词”来使文章的逻辑更清晰~In the IELTS writing test,we often use phrases called‘liking phrases’to link our ideas together，比如on the one hand,on the other hand,however,for example,nevertheless,firstly,secondly,in conclusion,in summary.
如果连接词后面接句子，常需加上逗号We normally use a comma after a discourse marker that introduces a sentence:
Firstly,xxx
On the one hand,xxx
However,xxx
To sum up,xxx
如果连接词在句子中间，前后都要加逗号We also use commas on either side of discourse markers in the middle of sentences:
Fossil fuels are mostly to blame for global warming,however,some people believe this is a natural process.
Fossil fuels are mostly to blame for global warming,for example,from cars and factories.
