2、在比较状语从句中，如果主语不是人称代词，常常可以在主语前添加助动词do(be)代替前面出现过的动词。这时，比较对象放在这个do(be)后面，形成一种部分倒装的形式;在the more引导的比较状语从句中，其所修饰的名词应随之移至主谓语之前，而形成部分倒装。例如：
1)He always spends more time on that useless matter than do the others.
2)The living standard of the people is higher than was the case ten years ago.
3)Many people take it for granted that the more children one has，the more secure one's late years will be.
3、在由no matter how，however和how引导的方式状语从句中，其后的形容词、副词应随其移至主谓语之前，而形成部分倒装。例如：
1)However hard he tried，he still failed in the entrance exam.
2)No matter how badly they had slept she was always up early.
