答案

below
表示在……下面的意思时,指处于比某物低的位置,不一定在某物的正下方.它的反义词是above.例如：
Write your name below the line．在线下写上你的名字.
We are below the moon．我们在月下.
under
表示在……下面的意思时,有时可与below通用,但它指处于某物的正下方,其反义词是over.例如：
He stood under a tree.他站在树下.
The cat was under the table．猫在桌子下面.
beneath
表示在……的下面的意思时,相当于below,尤其相当于under.但这是旧用法或文学用语,现在很少用.例如：
Children are playing beneath the window．孩子们在窗子下面游戏.
至于第二题,记住好了,关于...的思考/推测,常说 speculation concerning...或者speculation as to...或者speculation about~
而当speculation后面加of的时候,常常作“投机”讲~
