考点: 逻辑表达(Logical Predication)、动词形式(Verb Form)、指代一致(Agreement)
1) 分词短语在句首起状语作用,逻辑主语等于句子主语
2) it不能指代介词短语, it可以指代主语从句和不定式结构: It is difficult to do this research. It is important that we finish ontime. 在这两个例子中it分别指代to do this research和that从句
3) 现在完成时的时间状语
for, since, so far, ever, never, just, yet, till / until, up to now, in pastyears…
(A) 正确, after + n.结构避免了逻辑主语问题; less than 35 years after …符合习惯用法
(B) sincereleasing放在句首,逻辑主语等于句子的主语their descendants, 不符合逻辑; since是现在完成时的标志和had migrated矛盾; since的使用不符合习惯用法
(C) since是现在完成时的标志和had migrated矛盾; since的使用不符合习惯用法
(D) it不能指代介词短语from the release…
(E) it不能指代介词短语from the release…
求教A/B/C前半句的选项分析~~~~ABC前面的这个“less than 35 years after……”这个到底是什么成分 confusing啊!!!!谢谢同学们~~
问题补充:
我先说说我对正确句子的看法: Less than 35 years after the release of African honeybees outside Sao Paulo, Brazil, their descendants, popularly known as killer bees, had migrated as far north as southern Texas.
(问题1)我highlight了主谓,我觉得前面after是做had migrated时间状语(就是你说的verb modifer),问题是这个less than 35 years是干什么的呢??修饰after the release of blablah的吗?
在说B/C错误选项里。 (B) In less than 35 years since releasing African honeybees outside Sao Paulo, Brazil, (C) In less thanthe 35 years since African honeybees had been released outside Sao Paulo,Brazil, (问题2) 我按解析的理解是“since……”同样是时间状语,修饰had migrated,这才有了语法笔记里解释的的B的releasing的逻辑主语是their descedants,以及C选项里面的“since……”与had migrated的tense不符的问题。问题是,前面的这个in the less 35 years是干嘛的??修饰谁?
希望我把自己的问题讲清楚了~ |
