b not……until这里引导的从句,用一般现在时表示将来是,跟if引导的条件状语从句一样
c首先动作在进行,用进行时.主句是过去时,从句时间倒退一步也变为过去时.所以是过去进行时
b as有当的意思,可以引导时间状语从句.后面fell asleep表示他睡着了.这是一个状态,不可能用进行时表示的,不可能说他正在睡着了.
a 忘记也是一种状态,你不可能说正在忘记的.用一般现在时表示这种常态.
学英语要自己理解,不能光看语法,我都是自己进行逻辑分析理解的
1.B until相当于if not 用现在式
2.C 用过去进行式
3.A as引导的句子用过去式[as time went by],主句用过去进行式.
4.D 现在忘记了,所以用现在式
B 句子是一般现在时态
C 看见那个老人正在找东西
B 当她正在看报纸时.她已经睡着了
A 一般现在时态
