一、选择题 1．C 解析：C 【解析】 【详解】 句意：——我想要去看电影。——太晚了。你最好不要独自一人去。 本题考查非谓语动词。to go是动词不定式，go是动词原形，going是现在分词或动名词，would like to do sth想要做某事，因此第一空用to go。had better (not) do sth最好（不）做

某事，根据It’s too late.可知，太晚了，因此不要独自一人去，用not go，故选C。 2．B 解析：B 【解析】 【详解】 句意：火车来的时候你不能跟它一起跑，这很危险。 考查情态动词。may not可能不；mustn’t不能，表禁止；needn’t不需要。根据“It’s dangerous”及语境可知，此处是表达“你不能跟着火车跑”，在这儿应是不允许，强烈的禁止

的意思，故用mustn’t。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：你已经完成了大部分工作，所以你明天不必这么早就开始工作。你可以9点来。 本题考查情态动词。can't不可能，mustn’t禁止，needn’t不必，couldn’t可能不。根据You have finished most of the work可知，你已经完成了大部分工作，因此明天不必这么早就开

始工作，因此用needn’t，故选C。 5．D 解析：D 【解析】 【分析】 【详解】 句意：-我们现在能过马路了吗？-不，我们不能，我们要等到交通灯变绿。couldn’t不能；needn’t不需要，不必；shouldn’t不应该；mustn’t禁止，不要。根据句意We have to wait until the light turns green可知，在红灯的时候是禁止过马路的，因此这里的语气比较强，

故应选D。 6．A 解析：A
