重点讲解
一.above:prep.超过, 在 ... 上面, 高于 adj.上面的, 以上的 adv.在上面, 超过, 更重要地, 上文地 n.上面的东西
【语法用法】
作为形容词时，意为“上面的”，如the above list，the above statement；
也可做名词，如the above。above当单数或者复数均可，根据所指对象为单数或复数而定。
The above is a true story.
以上是个真实的故事。
The above are the essentials.
以上是概要。
同over在意思上略不同。above不一定有“垂直在上的”含意，over却有。如你在第一层楼，第二层楼是above你，但只有第二层楼的一小部分是over你。
【词义辨析】
above, on, over
这些前置词均含“在……上”之意。
above一般指位置高于某物，但不一定在正上方，也不接触另一物，其反义词是below。
on指与另一物表面相接触。
over指一物在另一物的垂直上方，多暗示悬空，但也含“覆盖于……之上”之意。其反义词是under。
【例句用法】
His conduct has always been above suspicion.
他的行为一直无可质疑。
This book is above me.
这本书对我来说是太难了。
二.against:prep.反对, 逆, 违背, 倚靠, 映衬, 防御, 相比,相对
【语法用法】
against用在fight，strive，struggle等词后面，同with意思相同，不过against更强调一种困难中的反抗。
We fight for the weak against the strong.
作为介词，against后接的宾语有时可省略。
He had intended to come but somehow decided against(it).
【例句用法】
We sailed against the wind.
我们逆风航行。
We have saved some money against our old age.
我们存了一些钱，以备老年之用。
