解题思路: 孩子 这题 结果了 怎么又出现了 是不是系统出问题了
解题过程:
1.The book was written in 1946,____the education system has witnessed great changes.
A.when B.during which C.since then D.since when
C 句意:这本书是1946年写的,从那时起教育体制见证了重大的变革。 孩子 the education system has witnessed great changes.是一个定语从句,先行词是1946,根据 has witnessed(现在完成时)可知,先行词 应该用 since when.(since 的主句是 现在完成时)
如:He has lived here for 5 years since he came.
孩子 since when 可以换为 and since then
若选A ,定从的时态 要用 一般过去时
B.during which 不正确,因为只能说 in 1946,而不能用 during 1946.
2.if you are traveling____the customs are really foreign to your own,please do as the Romans do.
A.in which B.what C.when D.where
D 句意; 如果你正在风俗习惯跟你自己国家的风俗习惯打不相同的地方旅行,请入乡随俗。
孩子 这是一个 Where 引导的状语从句,这类句子很好理解,相当于:if you are traveling there. there就是地点状语,本题中的状语只不过由句子来充当。
此句也可以变为 定语从句
if you are traveling in the place where the customs 如:
Put the book (in the place )where it was. 把书放在原地。
孩子 注意 本题 不能选A ,因为 若选A 就是定从 ,但定从又缺少先行词。
孩子 明白了吗?
最终答案:略
