快考试了,问几个纠结的SAT语法题,感激不尽~Elizabeth Ellet is best known for her historical accounts that focus on ordinary lives,especially (that of) women,rather than on larger political and socioeconmic events.括号里的是错的,
1. those of (that of 不能代指括号里应有的复数概念,即 the lives of,those of 则可.)
2. A 错,它不符合平行结构.请看： resulting either from a change in the direction or the speed of the wind. 连词 "either... or..." 连接的是不同结构,
符合平行结构：either from a change in the direction or from a change in the speed of the wind
这一来倒是符合了either后是一个 "from ...",or 后也是一个 "from...",但这将非常wordy.
B就对了,符合平行结构,either ... or... 各自后都是一名词：in either the direction or the speed of.
3. Different from 或 contrary to 均可,前者更自然,"opposite to"这么用属于用词错误.不要用汉语去译它,否则你还是会不明白它为啥错.汉语不也有用词不当的现象?“他的英语很好,冰冻三尺非一日之寒.”和“他现在成了阶下囚,冰冻三尺非一日之寒.”很多大报的记者都搞不清楚那句属用词错误.
4. particular about 对.挑剔
(She is very particular about food.)
5. （所给句子主语、谓语都无法准确判断,语义更不谈,照现在这样没法帮你.）
