短文/对话题型特点有提示词无提示词动词名词形容词、副词代词冠词连词介词连接词/情态动词/助动词/代词等

1.提示词为动词时：动词谓语非谓语词性转换时态语态语气主谓一致v-ingv-edtodov.→n.v.→adj.

如何判断该词是作谓语还是非谓语呢？谓语非谓语VS？

找主语Step1检查空格前后还有无其他动词Step2看句子中有无连词and,or,which等Step3Tip1

【确定时态的3条依据】(1)依据上下文时态一致。空格要填的动词时态一般应与上下文的时态一致。但需注意：客观事实或真理可能时态不一致.(2)依据并列谓语动词的时态一致。(3)依据时间状语。如recently,sofar,uptonow,uptothepresent,inthepastfewyears，for+一段时间since,常与现在完成时连用等。谓语动词：时态、语态、语气、主谓一致

当句中已有谓语动词，横线前又没有并列连词与括号中的动词并列时，所给动词就是非谓语动词（无连则非）。此时，就要根据非谓语动词的用法确定用具体的某种形式(doing,done,todo)。非谓语动词：v-ing,v-ed,动词不定式v-ing形式表主动、进行；v-ed形式表被动、完成；todo表目的、将来。逻辑主语
