英语导学案
Grammar
学能目标：
1.学生学会列举时间状语从句引导词，归纳总结各类引导词的用法及其特殊句型。
２.理解过去完成时及其用法，能正确判断句子时态。
PartOne:时间状语从句
时间状语从句主要有以下几个类别：
when,while,as(当……)
When引导的时间状语从句可以用延续性动词也可以用短暂性动词而While引导的时间状语从句用延续性动词;as侧重伴随，翻译为“随着……，一边……一边”
（when本身引导时间状语从句还满足主将从现原则）
Fatherwascleaningthecarwhile/whenIwasplayingcomputergames.
IwaswatchingTVwhenhecamein.
Astheywerepickingtea,thegirlsweresinginghappily.
Astimegoesby,wehaveabetterunderstandingofthingsaroundus.
