優(yōu)質(zhì)解答

below
表示在……下面的意思時,指處于比某物低的位置,不一定在某物的正下方.它的反義詞是above.例如：
Write your name below the line．在線下寫上你的名字.
We are below the moon．我們在月下.
under
表示在……下面的意思時,有時可與below通用,但它指處于某物的正下方,其反義詞是over.例如：
He stood under a tree.他站在樹下.
The cat was under the table．貓在桌子下面.
beneath
表示在……的下面的意思時,相當于below,尤其相當于under.但這是舊用法或文學用語,現(xiàn)在很少用.例如：
Children are playing beneath the window．孩子們在窗子下面游戲.
至于第二題,記住好了,關(guān)于...的思考/推測,常說 speculation concerning...或者speculation as to...或者speculation about~
而當speculation后面加of的時候,常常作“投機”講~
