3道 状语从句题目 Dew is formed ______ the grass is thick.A.when B.w
Dew is formed ______ the grass is thick.
A.when B.where C.which D.as
句子缺少的是状语,可以是时间状语,也可以是地点状语.从语法上来讲,AB都对.但当我们整个句子可以理解,就发现了逻辑上的差别:当草长得厚实的时候,露珠就形成了;和 在草长得厚实的地方,露珠会形成.根据客观事实可以排除when,因为露珠不是草长厚实了的时候就形成.
The motorist looked over the engine carefully ____ on the way.
A.so that it should go wrong.B.lest it should go wrong.
C.in order that should not go wrong.D.for fear that it should not go wrong.
B.先来看看四个项的意思.A这样它就会坏掉,B唯恐它坏掉;C目的是它不坏掉(但in order 后面接不定式,所以这个从语法上讲就是错的),D恐怕它不会坏掉(这个从语义上就可以排除).所以,带入原句,就可以知道答案了.
The lower ___ in a room,the more slowly our eyes focus.
A.the level of lighting B.light level C.leveling of light D.lighting is level.
这个句子套用的格式是the + adj/adv 比较级+ 主语(+be/谓语),the adj/adv 比较级+ 主语+be/谓语,所以空里缺少的只是个主谓结构或者主语+be的结构,四个项里只有D是这样的结构,但是D里的内容是不对的,level的形式不对,所以只能选不加谓语部分的内容,也就是A.
