how to do整体是理解为名词吗?我总是习惯还原句子。比如where are you fron 还原就是you are from where,i do not know how to do 还原就是i do not know to do how对吗?其中to do 做宾语,how做副词修饰do,这样理解对吗?
As pace of life quickens things tend to change fast in the city.1) Pace of life 前需要冠词a或the吗?2) As在此是连词,意思是“随着”还是“因为”?还是两者皆可?3) quicken things 两词之间需要加逗号吗?有无逗号有何区别?
