2、达的意思是：离开了你，我们本不可能完成这项工作。故答案为B项。情态动词用法归类与高考试题分析：（一）表示推测的情态动词 (1) must表示推测，意为“一定”，只能用于肯定句中。 must have done意为：一定做过某事或某事肯定发生了。 例如： She looks very happy. She _ have passed the exam.I guess so. Its not difficult after all. A. should B. could C. must D. might【解析】句意为：她看上去很高兴，一定是通过了考试。【答案】C(2) should (not) /
3、 ought (not) to在中表示根据常规或常识推测，表示“某事应该或不应该发生”，语气比must或cant / couldnt稍弱。 (3) can, could表达推测时，一般用于疑问句和否定句中；can用于肯定句中表示一种理论上的可能性，并不牵涉是否真的会发生，在这种用法中can只能与动词原形连用；could用于肯定句中，语气比may/ might更弱。 You _ be hungry already you had lunch only two hours ago!

5、not) / might (not)表达一种不太把握的推测，意为“或许，可能”；might的语气比may较婉转。例如： Liza _ well not want to go on the trip - she hates traveling.
