牛津实用英语语法:341 比较从句

　　C 形容词和不定式或动名词连用时的比较：

　　Its sometimes as cheap to buy a new one as(it is)(to)repair the old one.

　　Buying a new one is sometimes as cheap as repairing the old one.

　　有时买一个新的跟修理旧的一样便宜。

　　He found that lying on the beach was just as boring as sitting in his office.

　　He found lying on the beach just as boring as sitting etc.

　　他发现躺在沙滩上和坐在办公室里一样没趣/烦人。

　　He thinks it(is)safer to drive himself than(to)let me drive.

　　He thinks that driving himself is safer than letting me drive.

　　他认为自己开车要比让我开车更安全些。

　　It will soon be more difficult to get a visa than it is now.

　　Getting a visa will soon be more difficult than it is now.

　　不久之后，签证会比现在更难拿到。
