英语常用短语的用法与练习（3）
11. as for至于，关于；
用法：
as to 和as for表示“就……而论”“有关”或“至于”。但二者用法不尽相同。
as to 的功能类似于with regard to，regarding，on the matter of，concerning 等，常用于相当正式的语境中，尤其用于争论和做出决定时。可放于句首或与wh- 疑问词引导的动词不定式和名词性从句连用（有时可省略），而as for 无此种用法。例如：As to the journey，we must decide about that later.至于旅行，我们必须以后再作决定。as to 有时用于表示according to 的含义。例如：They sorted the eggs as to size and color.
as for 和as to 都可用于句首，引出一个与前一个话题稍微有些不同的话题，但as for 在语体上不如as to 正式，并且着重话题的转换，也就是说，它所引导的是前面尚未提到过的新的事情，因此它不能用于文章的开头。另外，as for 有时表达轻蔑的语气。例如：We had a delightful weekend in the country. As for the traffic，we had no difficulty.在乡下我们度过了一个愉快的周末。至于交通，我们没有遇到任何困难。
例句：
①As for you, you ought to be ashamed of yourself.至于你, 你应该感到
惭愧。
②You can have a bed；as for him，he'll have to sleep on the floor.
有一张床给你，至于他，就只能睡在地板上了。

as短语：
as to 至于，关于；提到；就……而论(至于，说到)；

12. pay attention to 注意；
用法：
pay attention to 后面可以直接加名词、代词或者动名词，但是值得我们注意的是，这里的to是一个介词，并不是能构成动词不定式的，这和look forward to是一样的。所以呢，这个词组后面要接动词的话，那麽就要在动词后加ing了。
例句：
①You should pay attention to your spelling.你要注意自己的拼写。
②We had paid attention to him. 我们已经注意到他了。
③They paid attention to watching the scene. 他们注意到了观察现场。attention短语：
bring sth. to one’s attention 使某事引起某人注意；call/draw one’s attention to sth. 使某人注意某事；draw/catch/attract one’s attention 引起某人的注意；fix/focus/concentrate one’s attention on sth. 集中注意力于某事物；
