一道SAT语法题,
When light from a distant source,（such as the sun,it strikes） a collection of water drops,such as rain,spray,or fog,a rainbow may appear.
(A) such as the sun,it strikes
(B) like the sun's,striking
(C) such as the sun,and striking
(D) such as the sun,strikes
(E) like the sun's,strikes
我选的是E,
句意是“当光线（就如阳光）从远处射来，当它照射到水珠（就像雨，浪花，或雾）时，彩虹就会形成”这里such as the sun是对前面的light的举例，就像后面such as rain, spray, or fog是对water drops的举例
注意前面是light from，那后面必须用地名
只能是light from the sun,不可能是light from the sun's
首先判断是插入语.插入语在句子中即使删掉也不影响句子结构.所以含有it strikes的都不对.因为如果这样的话,这句子就有两个主语（it 和 a collection of water drops）然后考虑：such as指代的到底是什么.是a distant...
such as the sun,做a distant source的同位语，由such as 引导
因为有逗号，所以strikes前要有IT作主语，指代前边的light
