考查情态动词辨析。
A项，必须，一定，表示肯定推测；B项，也许，表示有可能；C项，需要；D项，应该。
根据回答部分I’m not sure.可知，此处并不确定吉姆是开车来还是乘坐火车来，所以此处是“可能”。
故选B。
【点睛】must意为“必须，应该”，可以表示主观上一定要做什么或者肯定推测。
例如：I must go home to look after my mum. This pair of shoes must be hers. may意为“可以，也许”，可以表示请求或者推测（无法断定）。
例如：May I come in？ It may be hers，but I’m not sure. need意为“需要”，既是情态动词也是行为动词。
例如：You needn’t finish your homework right now. You need to tell him the truth. should意为“应该”，表示责任或者义务。
例如：You should finish practising playing the piano at first.2．B解析：B【解析】【详解】句意：——我想买郭敬明的《小时代》。
——你最好不要读他的书。
他讲的故事与现实生活相去甚远。
考查非谓语动词及固定句型。
短语would like to do sth.愿意去做某事；第一空排除AC；You had better+动词原形，你最好做某事；You had better not+动词原形，你最好不要做某事。
第二空排除D。
根据题意，故选B。
3．D解析：D【解析】【详解】句意：-我必须今天做完这个工作吗，妈妈？-不，你不必。
你可以明天完成。
mustn’t禁止，不要；can’t不能，不会；shouldn’t不应该；needn’t不必，没有必要。
Must 的一般疑问句，肯定回答用must，否定回答应用needn’t。
故选D。
4．C解析：C【解析】【详解】句意：--听! 狼在叫! --它不可能是狼，因为狼从来不会在这个时候出来。
A. mustn’t禁止；B. needn’t没有必要；C. can’t不可能；D. don’t构成一般现在时的否定句。
根据“because a wolf nev er comes out at this time因为狼从来不会在这个时候出来”，可推断它不可能是狼，故选C。
【点睛】情态动词表推测的用法：can表示“可能”；can’t表示“不可能”；may表示“可能”，must表示“一定”，注意mustn’t表示“禁止”不表示推测，表示否定推测要用can’t.5．C解析：C【详解】句意：——你认为网上购物安全么？——我觉得是的。
淘宝上，消费者可以无理由退货，但是他们要承担运费。
考查情态动词辨析。
A. can’t; can不能，能；B. must; must必须，必须；C. can; have to可以，不得不；D. mustn’t; can禁止，能。
根据句意表示的是顾客能退货，是可以，第一空用can；但是不得不承担运费，非主观情愿用have to。
故选C。
6．D解析：D【解析】【详解】句意：——我不能戒烟，医生。
——为了你的健康，恐怕你得这么做。
考查情态动词辨析。
must必须，强调主观意愿；can能，表能力或许可；need需要，指有必要；have to必须，强调客观需要。
根据“For your health为了你的健康”，可知无论愿不愿意戒烟是健康所需，故选D。
7．D解析：D【解析】【分析】【详解】句意：设计者已经尝试了所有可能的方法使机器变轻，所以你不必担心它的重量。
must必须；一定；may可以；可能；can’t不能；不可能；needn’t不必，没有必要。
根据句意The designer has tried every possible way to make the robot light可知，设计者在努力使机器变轻，所以担心是没有必要的。
