  1.huan/people/person

  huan主要指“人类,人”;

people意为“人们”,着重指全体,是单数形式,但表达复数概念,等于enandoen;

person也可以作“人,人们”着重指个人方面,可以说topersonshuan--huans

  certainadbecertainofsth,/doingsth.

  sureadcertain与sure的含义和用法大致相同,但certain侧重于表示有确定依据或事实,语气比sure强,多作表语,主语可以是物也可以是人;

sure多指主观上相信某人或确定某事,主语一般是人.

  Itiscertainthatnobodyliesaiting.

  eg.ecarefullyparethefirstreportiththesecond.

  Itisinterestingtoparetheirheightandoureight/

  crodedad可以作定语也可以作表语,意为“挤满的,拥挤的”常用结构是becrodedithsth.

  ThisistheostcrodedstreetinShanghai.

  Thebusiscrodedithpeoplehogotoor.

  anuberof,thenuberof的区别

  anuberof=nubersof+可数名词的复数+动词形式为复数

  AnuberofvisitorsetoSuzhoueveryday.

  thenuberof+名词的复数+动词的三单意思是“……的总和数量

  Thenuberofthestudentsinourclassis65.

  athalfthespeedoflight以光速的一半,at

  Eg:

Thecarisrunningat80iloetresanhour.

  Iboughtitataloprice.

  three-eighths八分之三,在分数词的表述中,记住口诀“分子基数词分母序数词,分子大于1,分母加s”。

  如:

1/3onethird5/6fivesixths

  Eg:

Tothirdsofthestudentsinourclassareboys.

  every和each的共同点和不同点

  every和each后加单数名词,动词用第三人称单数形式。

Eachoftheboysinclass2hasboughttheboo.

Everystudentislisteningtotheteachercarefully.

  each是一定数目中的每一个,强调“个别”“各有不同”,each是代词,可以和of连用。

  every只数目不确定中许多人或物中间的“每一个”,强调“总和”更强调“大家一致”。

every后不可以跟of
