答案：
解析：
【小题1】主语是few students，谓语动词就应该使用复数形式。学生是被要求，因此我们判断，谓语动词应该是be asked，而这个句子是一个反意疑问句，疑问词是are，所以答案为are asked.
【小题2】这是promise后面的宾语从句，主句谓语动词promised 用一般过去时，从句必须使用和过去相关的某种时态，根据句意：警察承诺他们会尽可能快的解决这件事，故答案为would solve。
【小题3】句子缺谓语动词，we look forward to 是定语成分，根据时间状语this Saturday 可以判断，旅行是将要被举行，take place 无被动语态，所以应该是will take .
【小题4】already 常和完成时连用，此题是两个并列的分句，第一个分句用一般过去式，相应的第二个分句就应该使用过去完成时。
【小题5】尽可能跑快的目的是赶上他的朋友，用动词不定式作目的状语，所以是To catch.
【小题6】从时间状语in the last few years“在过去的几年里”可以判断，中国发射宇宙飞船入太空这个动作发生在过去，但和现在相关，所以要使用现在完成时，答案为 has sent.
【小题7】这个句子的理解为：“去年被我同学组织的慈善表演非常的成功。”organize 和show之间形成逻辑上的动宾关系，在句子中作定语。故答案为：organized。
【小题8】because引导的原因状语说明没理解的原因：是因为说话的那一刻正在打字，表示过去某个时间点正在进行的动作，用过去进行时，所以答案为：was typing.
