通过锦囊三：三招攻克动词难点
1.结合语境，推敲状语，确定动词时态
语法填空常需要结合语境来确定答案。如果文章的整体时态为过去时，动词的时态应是与过去相关的时态：一般过去时， 过去进行时，过去完成时等。此外，熟记各种时态的常用时间状语，对于确定时态有极大的帮助。如：since, so far, up till now, in the past years等是现在完成时的标志；years ago, yesterday, last night是一般过去时态的标志词；by the end of last (next) month, when he got/gets to the station, before he did sth。常用于过去(将来)完成时态；always 常用于一般现在时和带有感情色彩的进行时等。但是，做题时仍需结合语境，切忌教条主义。如：
I was in Hangzhou on business for a week last month.There I was greatly struck by the beauty of the West Lake.
2.熟记句型提高速度
(1)It’s time sb. did/should do sth.
(2)sb. would rather did/had done sth.
(3)was/were doing sth....when...
(4)no sooner ...than... hardly...when... scarcely...when.。。句型中主句用过去完成时，从句用一般过去时。如：No sooner had he arrived than it began to rain.
(5)had wanted/hoped to do sth.
(6)It won’t be long before...
(7)It’s/has been+some time+ since sb. did sth.
(8)Would you mind if I did sth.?
(9)be (was/were) about to do sth....when...
