注意 “特殊疑问词+ever”构成的单词还有whoever（无论谁），wherever（无论在哪里），whatever（无论什么），however（无论怎样）等，引导让步状语从句时，都可以和“no matter+疑问词”进行替换。
Whatever you do, you must do it well.=No matter what you do, you must do it well.无论你做什么，必须做好它。

Unit8 Section A Grammar focus-4c 分层作业答案与详解
一、根据语境从括号内选择正确的情态动词填空。
【答案】
1．must 2．might 3．must 4．can't 5．may not 6.could might can't 7．. can't may could
【详解】
1．句意：多穿点衣服。只穿一件衬衫你一定会感觉很冷。
must一定，准是，表示推测，只用于肯定句中；can’t不可能，表示否定的推测。根据句意Put on more clothes可知，这里应表示肯定的意思，故填must。
2．句意：天空中有一些灰色的云，一会儿可能会下雨。
may not可能不；might可能。两个词都可以表示推测，语气比较弱。根据句意There are some grey clouds in the sky可知，这里应该是肯定的推测，故填might。
3．句意：大家都在离开办公室，这一天一定是结束了。
couldn’t不可能；must一定，表示推测，用于肯定句中。根据句意Everyone is leaving the office可知，大家都在离开，说明下班了，故这里是肯定的推测，填must。
4．句意：他们公寓里的等都灭了，他们没有接电话，他们一定没有在家。
can’t不可能，一定不；must一定，肯定。根据句意The lights in their apartment are all off. They're not answering the phone可知，这里表示否定的推测，故应填can’t。
5．句意：James可能不来参加聚会，他说他不确定他的计划。
may not可能不，语气较弱；can’t不可能，语气非常强。根据句意He said he wasn't certain what his plans were.可知，这里表示的推测语气较弱，故应填may not。
6．句意：我想我听到了敲门声，可能是我的弟弟，他通常这个时候回家。或者可能是我的妈妈，不可能是我的爸爸，他从不敲门。
第一个空must肯定；could可能。根据句意可知，这里没有十足的把握说一定是…，故应填could；第二个空用might也表示语气弱，“可能”；第三个空用can’t表示“不可能”，语气较强，因为后面说了He never knocks，他的爸爸从来不敲门，所以一定不是他。
7．句意：我把钥匙放在哪儿了？他们不可能走开了。他们可能在洗脸盆附近，因为我从花园进来的时候洗手了。或者他们可能在我园艺裤的口袋里。
根据句意可知，钥匙不会走路，故第一个空表示非常肯定的推测，应填can’t不可能；第二个空和第三个空都表示猜测，没有确切的依据，只是有可能，故第二个空填may“可能”；第三个空填could，也表示“可能”；must是一定，语气非常肯定，不符合句意。
二、单项选择

A．must B．mustn’t C．needn’t D．can

A．must B．might C．ought D．will
【答案】B
