SAT语法题2道 1.The Pacific Northewest (averaging 4000 wildfires a year,caused mostly) by lighting.A.原句B.averages 4000 wildfires a year; most are caused D.with an average of 4000 wildfires a year,caused mostly PS：括号内是A选项问：为
第一个句子,A和D选项把句子主干挑出来都是：The Pacific Northwest caused mostly by lighting.显然是不对的,无法构成逻辑关系.而且从句意上看,不是The Pacific Northwest由于雷电引起,而是指wildfires由于雷电引起.因此,用most (of the wildfires) are caused by ...就是正确的.再者,两个完整句子之间用分号“；”来连接是可以的,因此B是正确答案.
第二题,such as 后面应加上名词或V-ing.如果把finding看成名词的话,至少要说成the finding of ...,因此这儿的finding只能是v-ing形式,故C是正确的.

1. 把正确答案带入：
The Pacific Northewest averages 4000 wildfires a year; most are caused by lighting.
这样构成了两个句子。其谓语分别是：averages和are caused 。符合语境，符合于法要求。
太平洋西北平均每年发生4000起（森林）野火。他们大部分是由闪电引起的。

如果填入D：
The Pacific Northewest （with an average of 4000 wildfires a year）, caused mostly by lighting.
这样的话：The Pacific Northewest是主语。caused是谓语。
不知所云。


2. such as finding of the shortest path to a food source ，应该理解为：诸如对食物来源捷径的发现。
such as finding the shortest path to a food source，应该理解为：诸如发现了食物来源的捷径。
这两句话的侧重点是不一样的。
finding of 是个of名词词组，强调状态，表示一种静止的结果。
finging 是个动名词结构，强调动作，表示动态的结果。
