[语法精析]
◆[基本用法]
一、动名词用作表语
动名词作表语，表示抽象概念。动名词作表语一般用来表示“身份、职业”等，大部分时侯主语与表语可以互换。此外，还要注意主语与表语的一致性。
Her job is checking letter of credit and terms of contract.
她的工作是核对信用证和合同条款。
That is not playing the game.
那样做就不公平了。
This was really carrying matters a little too far.
这做得真有点太过分了。
二、不定式作表语
不定式作表语，表示主语的具体内容，如职业、职责或性质等，也可以表示目的、愿望等。不定式作表语通常可以和主语位置互换。
My dream is to be a doctor.＝To be a doctor is my dream.
我的梦想是成为一名医生。
注意：如果作表语的不定式是解释主语中 do 的具体内容，不定式中的 to 可以省略。
All I did was(to)turn off the gas.
我所做的就是把煤气关掉。
