person也可以作“人,人们”着重指个人方面,可以说twopersons
human--humans

fivesixths

(2)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

四.语法知识
一.“must,can/could,may/might+动词原形”常用来表示对现在或将来发生情况的推测。
①must只用于肯定句中,表示“一定、肯定”。
其否定mustn’t表“不准、禁止、不可以”等。
如:
Henevertakesataxi.Hemustbeverypoor.
Ithoughtyoumustlikesomethingtoread,soIhavebroughtyousomebooks.
我想你一定喜欢看点东西,所以我带来了些书。
注意:
含有mustbe的反意疑问句,常用“is/are+主语”。
含有mustdo的反意疑问句常用“do/does+主语”。
②can/could多用于否定句或疑问句中,偶尔用于肯定句中表示一种可能性。
如:
Attendingaballcanbeexciting.
michaelcan’tbeapoliceman,forhe’smuchtooshort.
迈克不可能是警察,因为他太矮了。
③may/might通常用于肯定或否定陈述句中。
当表示某事可能发生时,可用could,may,might.如:
—Areyoucomingtojeff’sparty?
你来参加杰夫的晚会吗?
—I’mnotsure.Imay/mightgototheconcertinstead.
不太确定,我有可能去参加音乐会。
二、could/can,may.
might表示“请求、建议、许诺、能力”等。
could/may用于表示委婉地提出请求或允许,“给予请求”的答复用can/may.could/might也可以表示“许可”,语气比can/may委婉,表示的可能性较小。
如
—couldIcallyoubyyourfirstname?
—yes,youmay/can.
二.宾语从句
(1)that:
陈述句充当宾语从句,由that引导,that不在从句中担当成分,只起连接作用,常可省略
if/whether:
一般疑问句充当宾语从句时,用if/wtether引导,宾语从句的语序是陈述句语序,但在ornot之前,不定式之前,介词之后只能用whether
宾语从句中常见的错误
一.连词错误
例1:
Heasked________therewasabookshopinthestreet.
A.that
B.what
c.how
D.whether
错解:
A;正解:
D
剖析:
ask表明了宾语部分含有询问的意思。
而that不能引导疑问语气的句子。
例2:
Tellme______youwillgowithusorstayathome.
A.if
B.whether
c.that
D.how
错解:
A;正解:
B
剖析:
引导宾语从句时,if和whether常可以互换,但有些情况是不能互换的?
穴当从句中提出了两种选择,或从句位于介词后面,只能用whether?
雪。
二.语序错误
例1:
Hewantedtoknow_______.
A.whenwouldtheholidaybegin
B.thathehadcomebackfromBeijing
c.whichonedidIlikebest
D.howhecouldgettothestation
错解:
A/c;正解:
D
剖析:
宾语从句必须用陈述句语序。
例2:
Iwonder____.
A.whobrokethewindow
B.whothewindowbroke
c.whosecoatisthis
D.whatisthepopulationofchina
错解:
B;正解:
A
剖析:
B貌似陈述句语序,但在这里连接词who是从句的主语,而不是thewindow。
三.结构错误
例:
Idon’tknow________.
A.whichroomIcanlive
B.whichroomcanIlive
c.whichroomIcanlivein
D.whichroomcanIlivein
错解:
A;正解:
c
剖析:
如果连接词在宾语从句中充当不及物动词后介词的宾语,并被放到从句句首时,不及物动词后的介词不能少。
四.时态错误
例1:
Long,longago,peopledidn’tknowtheearth___roundthesun.
A.moving
B.moved
c.moves
D.went
错解:
B/D;正解:
c
剖析:
在学习宾语从句时,我们知道主从句的时态要考虑“一致”的原则。
但当从句表示的是科学真理、格言、客观事实或其他不受时间限制、影响而客观存在的事物时,宾语从句的动词时态不受主句时态的限制,仍可用一般现在时。
例2:
couldyoutellme_______?
A.howIcangettothepostoffice
B.howcanIgettothepostoffice
c.howcouldIgettothepostoffice
D.howIcouldgettothepostoffice
错解:
D;正解:
A
剖析:
主句中的could在这里不是表示过去时态,而是表示语气的委婉。
