初一至初三全程英语知识点总结及练习1

  1 a bit/ a little
  这两个词都意为"一点儿"有时可以互换,但有时不能。
  ⅰ.二者作程度副词修饰形容词、副词、动词或比较级时,意义相同,为"一点儿" "有些"。如:
  ①i am a bit / a little hungry. 我有点饿。
  ②he walked a bit / a little slowly. 他走路有点慢。
  ⅱ.二者都可以作名词词组,充当主语或宾语。如:
  ① a little / bit is enough for me. 我有一点儿就够了。
  ② i know only a little / a bit about her. 我对她的情况只了解一点。
  ⅲ。a little可直接修饰名词;a bit后须加of才可以。如:

  [注意] a little of 后的名词通常特指,表"……中的一些",如:
  ①may i have a little of your tea?
  ⅳ. 否定形式 not a little 作状语,相当于very/ quite, "很", "非常";作定语和宾语时,相当于much, 意为 "许多"。而not a bit 作状语时,相当于not at all, 意为"一点也不",作宾语时则相当于not much. eg:
  ①he is not a little (=very) hungry. 他饿极了。
  ②he is not a bit (=not at all) hungry.他一点也不饿。
  ③she ate not a little (=much). 她吃得很多。
  ⅴ. not a bit 中的not 可以分开使用;not a little中的not 则不能分开。eg:
  ①he felt not a bit tired. = he didn’t feel a bit tired. 他觉得一点也不累。
  ②he felt not a little tired. 他觉得非常累。但不能说:he didn’t fell a little tired.
  §2 a few/ few/ a little/ little

  [注]:这几个词按语意的强弱来排,其顺序为:
  because— since— (as)— for
  §50 as/ when/ while

  ②when we were at school, we went to the library every day.我们在求学的时候,每天都到图书馆去。
  ⅲ. while "当(在)……的时候"表主句的动作或事情发生在从句中的动作或事情的进展过程之中。从句通常为进行时态。它有时可与when通用,但它只能指一段时间(a period of time),而不能指一点时间(a point of time)如上面的第一个例子。又如:
  ①please don’t talk so loud while others are working. 别人在工作的时候,请勿大声讲话。
  ②while i am washing the floor, you can be cleaning the windows.我洗地板时,你可以擦窗户。
