►Alice got up and ran across the field after it.艾丽丝站起来并跟着那只兔子跑过田野。
①after it与动词run连用,意为“跟着它跑,追赶着它”。run after也是一个固定词组,意为“追求,追捕,追赶”。
eg:The police are running after the man named John Smith.警察正在追捕那个叫约翰·史密斯的人。
②【辨析】cross,across与crossing
cross作动词,意为“穿过”,指从物体表面穿过;across作介词,意为“横过,穿过”,从一边到另一边;crossing作名词,意为“路口”。
【注意】若动词go,run,swim等后接上across,就相当于cross。
►nothing strange 没什么奇怪的
nothing是不定代词,strange是形容词,形容词修饰不定代词时,要放在不定代词之后。
►go down下去,下沉,消逝
eg:The sun goes down in the west.太阳在西方落下。
►while表示“当……时候”,主要用于引导时间状语从句。while引导的从句中的谓语动词必须是延续性或表示状态的词。
►【辨析】think of与think about
①两者表示“考虑,对……有某种看法”时,可互换使用。
eg:They are thinking about/of buying a new car.他们正在考虑买一辆新车。
What do you think of/about the film?你认为那部影片怎么样?
②think of表示“想到,想起”等意义时,不能与think about互换。
eg:Who thought of the idea?谁想到的那个主意?
I can't think of his name.我想不起他的名字。
