You (must / can't) be feeling cold with only a shirt on. 2．There are some grey clouds in the sky. It (may not / might) rain later. 3．Everyone is leaving the office. It (couldn't / must) be the end of the day. 4．The lights in their apartment are all off. They're not answering the phone. They (must / can't) be at home. 5．James (may not / can't) come to the party.

They (must / may) be near the sink (洗脸盆), since I washed my hands when I came in from the garden. Or they (could / must) be in the pocket of my gardening pants. 【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 8．Hey, boys! You ________ swim in the river. It’s dangerous. A．must B．mustn’t C．needn’t D．can 【答案】B 【详解】句意：嘿，男孩们！你们禁止在河里游泳。很危险。 考查情态动词辨析。must必须；mustn’t禁止；needn’t不必；can能够。根据“It’s dangerous”可知，河里游泳很危险，所以禁止这种行为，故选B。 9．—Who is playing the piano in the next room? Is it Jane? —It ______ be her. She has gone to Hefei. A．can’t B．mustn’t C．needn’t D．wouldn’t 【答案】A 【详解】句意：——谁在隔壁房间弹钢琴？是简吗？——不可能是她。她去合肥了。 考查情态动词。can’t不可能；mustn’t禁止，不得；needn’t不需要；wouldn’t不会。根据“She has gone to Hefei.”可知，简去合肥了，在隔壁房间里弹钢琴的人不可能是她，用can’t表示否定推测。故选A。 10．Ted __________ go to the party with us tonight, but he hasn’t decided yet. A．must B．might C．ought D．will 【答案】B 【详解】句意：特德今晚可能和我们一起去参加聚会，但他还没有决定。 考查情态动词。must必须；might可能；ought应该；will将。根据“he hasn’t decided yet”可知，还没决定是否去参加聚会，也就是可能会去。故选B。 11．To make more money, he made a ________ to do two part-time jobs. A．mistake B．noise C．difference D．decision 【答案】D 【详解】句意：为了赚更多的钱，他决定做两份兼职。 考查名词辨析。mistake错误；noise噪音；difference差异；decision决定。根据“To make more money, he made a...to do two part-time jobs.”可知他决定做两份兼职来赚更多的钱，故选D。 12．—Why are you so ________? —I stayed up too late last night. A．pleased B．excited C．sleepy D．puzzled 【答案】C 【详解】句意：——你怎么这么困？——我昨晚睡得太晚了。 考查形容词辨析。pleased高兴的；excited兴奋的；sleepy困倦的；puzzled迷惑的。根据“I stayed up too late last night.”可知，昨晚熬夜太晚，现在应该是很困。故选C。 能力提升 三、填写适当的句子补全对话 根据下面对话中的情境，在每个空白处填入一个适当的语句，使对话恢复完整。 A: Anna, you look worried. 13 ?

Let’s go now. 【答案】 13． What’s the matter/What’s wrong 14．Don’t worry 15．What color is it 16．Did you leave it there 17．I think we must find it 【导语】 本文是Anna和Jenny的对话，主要谈论了帮助Anna找笔记本的过程。 【详解】 13．根据前句“Anna, you look worried.”及下文“I can’t find my notebook anywhere.”可知此处应询问Anna“怎么了”。故填What’s the matter/What’s wrong。 14．根据后句“Let’s find it together.”可知此处应表示安慰“别担心”。故填Don’t worry。 15．根据答语“It’s black.”可知此处应询问“它是什么颜色”。故填What color is it。 16．根据答语“No. I went to the reading room just now, but it wasn’t there.”可知此处应用一般疑问句询问“你是不是把它落在那里了”。故填Did you leave it there。 17．根据前句“Then let’s go to the Lost and Found of our school.”及下文“Oh, I hope so.”可知此处应表达“我认为我们一定能找到它”。故填I think we must find it。 拓展训练 阅读单选 Helping others is a great thing to do, You can learn new things and have fun.
