lk thrugh浏览;快速阅读
Every evening,my mther lks thrugh magazines at hme.每天晚上,我妈妈都在家浏览杂志。
lk thrugh是一个动词短语,意为“浏览;快速阅读”。
与lk 有关的常用短语:
1.Here is the bk.First　　　it and then tell me what yu think f it.  A.lk int B.lk thrugh  C.lk up D.lk after2.We shuld learn t 　　　 urselves in life.  A.lk at B.lk fr C.lk after D.lk up
at a time每次,一次
In thse days,bks were nly prduced ne at a time by hand.在那个年代,书籍是靠手工制作的,一次只能制作一本。
at a time意为“每次,一次”,它常与表示数量的词语连用,表示频率。
at times意为“有时,不时”。例如:She calls n me at times.她有时来看我。
Pay attentin:nly ne persn can enter the rm 　　　.　 A.at ne timeB.n timeC.at a timeD.in time
result v.(因……而)产生;发生
A trade in bks resulted,and mre peple learnt t read.书籍买卖产生了,并且更多的人学着阅读。
result在此句中作动词,意为“(因……而)产生;发生”。
result还可以作名词,常见短语as a result“结果;因此”,相当于副词,在句中作状语。As a result,there were nt many bks,and they were expensive.结果,书籍数量不多,价格又昂贵。注意:as a result f意为“由于”,表示原因,相当于because f。As a result f his father’s illness,he left schl.由于他父亲生病,他辍学了。
We were all late 　　　 the heavy snw. A.as a result B.as a result fC.because D.s that
Later,develpments in printing made it pssible t prduce bks mre quickly and cheaply.随后,印刷术不断发展让制作书更快捷、更低廉成为可能。
本句中it作形式宾语,真正的宾语是动词不定式短语t prduce bks mre quickly and cheaply。
it作形式宾语时,需具备两个条件:一是真正的宾语是不定式或从句;二是有宾语补足语。1.it代替不定式短语。例如: I dn’t think it difficult t learn English well. 我认为学好英语并不困难。2.it代替宾语从句。例如: We all thught it a pity that the sprts meeting was cancelled. 运动会取消了,我们都觉得很遗憾。
