2)over, above, on
over, on和above都可表示“在……上面”,但具體含義不同。Over表示位置高于某物,在某物的正上方,其反義詞是under。 above也表示位置高于某物,但不一定在正上方,其反義詞是below。On指兩個(gè)物體表面接觸,一個(gè)在另一的上面。例如:
There is a bridge over the river.
We flew above the clouds.
They put some flowers on the teacher’s desk.
3) across, through
across和through均可表示“從這一邊到另一邊”,但用法不同。Across的含義與on有關(guān),表示動(dòng)作在某一物體的表面進(jìn)行。Throgh的含義與in有關(guān),表示動(dòng)作是在三維空間進(jìn)行。例如:
The dog ran across the grass.
The boy swam across the river.
They walked through the forest.
I pushed through the crowds.
4) in front of, in the front of
in front of 表示“在某人或某物的前面”,在某個(gè)范圍以外;in the front of 表示“在……的前部”,在某個(gè)范圍以內(nèi)。例如:
There are some tall trees in front of the building.
The teacher is sitting in the front of the classroom.
