Question

He put up his hand ____________ his head.
A.above B.over C.on
How to choose,translate and why?All OK?Why?Thanks.

Answer 1

选B over
above 和over都可以表示位置、地位、数量（表示“超出”这意）等.
当表示位置时,
above指笼统的上方,
over指垂直的上方,有“覆盖”的意思.
on含有表面接触的意思.
若不理解,可进一步看下面的例句：
above ,on, over
1. above“在...之上”, 表示位置之高.只是笼统的说“在...之上”,并不一定会有“在...之上”之意.其反义词为below.
eg. His office is above ours.
2. over 和above不同, 表示垂直向上.比较精确,其反义词为under.
eg. The lamp is over the table.
3. on“在...之上”, 物体与物体表面相接触, 一件东西在另一件之上.
eg. There is a book on the desk
Tanks have guns on them.
