2021年中考英语介词的用法总结(2)


    2)over, above, on
    over, on和above都可表示“在……上面”,但具体含义不同。Over表示位置高于某物,在某物的正上方,其反义词是under。 above也表示位置高于某物,但不一定在正上方,其反义词是below。On指两个物体表面接触,一个在另一的上面。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“从这一边到另一边”,但用法不同。Across的含义与on有关,表示动作在某一物体的表面进行。Throgh的含义与in有关,表示动作是在三维空间进行。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”,在某个范围以外;in the front of 表示“在……的前部”,在某个范围以内。例如:
    There are some tall trees in front of the building.
    The teacher is sitting in the front of the classroom.
    介词的固定搭配
    介词往往同其他词类形成了固定搭配关系。记住这种固定搭配关系,才能正确使用介词。
    (1)介词与动词的搭配
    listen to , laugh at, get to, look for wait for, hear from, turn on, turn off, worry about, think of, look after, spend…on…, 等。
    (2)介词与名词的搭配
    on time, in time, by bus, on foot, with pleasure, on one’s way to, in trouble, at breakfast, at the end of, in the end等。
    (3)介词与形容词的搭配
    be late for, be afraid of, be good at, be interested in, be angry with, be full of, be sorry for等。
