SAT 语法题
1.Let us now praise famous (men revolutionized the art of documentary photography,it depicts the American South during the Great Depression.)
Men revolutionized the art of documentary photography with its depiction of the American South during the Great Depression
为什么不能选:Men,which depicts the American South during the Great Depressin,revolutionizing the art of documentary photography.
2.(Concerned about possible damage to) the atmosphere's ozone layer,laws in many countries now prohibit the use of fluorocarbons as propellants in aerosol cans.
Because of concern about possible damage to
但是这样主语不就是laws?
为什么答案不能选 People are concernd about possible damage to
1.第一个问题你没注意到 要选Men,which depicts the American .的话 其中的很明显的问题which的先行词是men 这是不可能的,其次原文已给出 是 it depicts,it指代的是 the art of documentary photography,所以即使要用which depicts the American .也应该放到 photography后而不是men后.
2.解释第一个小问题:你注意 because of 后面的concern是个名词:担心,顾虑
就好比 Because of A,B hit C 一样它不是非谓语动词结构 也不是连词省略结构,主语可以不一样.
所以翻译成 出于对.的担心
解释第二个问题:你要问这个问题就说明你没注意到英语文法里的一个最最基本问题:“,”—逗号不能当连词使用,它不能领起一个主谓结构.一句话里不管有多少个逗号只要没有连词且只有一个句号或分号就只能有一个主谓结构.
这一点是很重要的,如 She is a teacher,she likes shopping.这句话是错误的,这里有两个主谓短语代表两句话,要么 She is a teacher,who likes shopping/liking shoping.变成定语从句或非谓语动词
要么 She is a teacher,and she likes shopping.像这样添加连词.
相反 分号和句号都能代表一个句子结束,可另起一个主谓结构:
She is a teacher; she likes shopping.
所以:People are concernd about 一个主谓结构然后逗号再 laws prohibit 在一个主谓结构中间没有连词,这是错误的.在正式语法里这是基本要求.
正因如此才会有这样的句子
Because the weather was good,we went out for a picnic.
The weather being good,we went out for a picnic.
The weather was good,and we went out for a picnic.
The weather was good;we went out for a picnic.
