2.allow的用法
allow+noun.
allowsb.todo/nottodosth../sb.isallowedtodo
allow+doing
(1)Heallowednonoisehere.
(2)Heallowedhisboytospendtheweekendwithhisfriends.
(3)Whydidyouallowhertosmokehere?
(4)Wedon'tallowdrinkingatschool.
3.once是连词,作“一旦……就……”讲。
(1)Onceshearrives,wecanstart.
(2)Onceyourealizeit,youwillstudyhard.
(3)Onceseen,itcanneverbeforgotten.只要见过一次就难以忘怀。
注意once一般和现在时连用。
4.unless是连词,相当于if……not……
(1)Hewillnotcomeunlesshishomeworkisfinished.==Hewillcomeifhishomeworkisfinished.
(2)Youwillbeintroubleunlessyoufollowmyinstruction.==Youwillnotintroubleifyoufollowmyinstruction.
unless和not…until的区别
unless引导从句时多强调条件,而not……until句型则强调时间。
Unless连接的主从句的时态一般是主句是将来时而从句现在时。
not……until连接的主从句中可以使用多种时态。
比较:
(1)Youwillfailintheexamunlessyoulistentotheteachercarefullyinclass.
(2)Wewon'tstartuntilBobcomes.
(3)Hedidn'tfindoutwhathadhappeneduntilhiswifetoldhimaboutit.
5.Don'ttouchanythingunlessyourteachertellsyoutodo.
在此句末的to后省略了touch。
在英语里,有些动词像hope,like,want,try,need,助动词如beableto.,begoingto之后,为了避免前后重复,往往只用一个to代表动词不定式。
(1)Youcangowithmeifyou'dliketo.
(2)Youmaystayathomeifyouwantto.
(3)Idon'twanttogothere,buthe'sgoingto.
6.Whataboutwhenweleave?
Whatabout……?
与Howabout……?
可以用来询问消息、提出建议或征询意见,其后可接名词、代词、动名词、副词(如next)和状语从句等。
(1)I'mready.Whataboutyou?
(2)Whataboutplayingfootball?
(3)Whatabouttoday'smatch?
7.makesure后跟了一个省略了that的从句。
当表示“弄确实、使确定”意思时,常用在祈使句中,其后的从句里要用一般现在时。
当makesure表示“认为、确信”的意思时,其后的从句时态可视情况而定。
(1)Makesure(that)youcomeearlytomorrow.
(2)Makesure(that)yourroomisclean.
(3)Wemadesureyouwerenotcomingtoday.我们认为你今天一定不来了。
8.turnoff其反义词是“turnon"
turnup(开大)其反义词是turndown(关小)
9.attheendof/intheend
attheendof意为“在……末,在……尽头”,既可以表示时间的概念也可以表示空间的概念。
而intheend只能表示时间的概念,其后不能接of短语,相当于finally,atlast.
(1)Attheendofthistermwewillhaveafinalexamination.
(2)Hediedintheendthoughthedoctorstriedtheirbest.
(3)Thereisahospitalattheendofthisroad.
10.with表示“具有,带有”
(1)Chinaisacountrywithasplendidcultureandalonghistory.
(2)Mr.Smithisamanwithtwosons.
(3)Iliveinahousewithtwowindows.
11.YoumustdoeverythingasIdo.
as为连词,表示方式,意思是“按照、如同”
(1)Statethefactsastheyare.要如实地陈述事实。
(2)Whydidn'tyoudoasIasked?
like/as的区别
like表示“像、如同”的意思是介词,其后不能跟从句。
而as是连词,要接一个从句。
as当作介词时表示“作为”。
(1)Hedoesn'tspeakasothersdo.(如、像)
(2)Hehasabignoselikehisfather.像)
(3)HeworksintheschoolasateacherofChinese.(作为)
12.insteadof/instead
insteadof是介词短语。
意思是“代替、而不是”。
其后可以接动名词、不定式、介词短语和名词、代词。
可放在句首或句尾使用。
(1)Ifyouarebusy,letmegoinsteadofyou.
(2)Theywentthereonfootinsteadofbybus.
(3)ThissummerIwenttoQingdaoinsteadofgoingtoBeijing.
instead是副词。
试比较。
(1)Parentsshouldgivetheirchildrenmoreadviceinsteadofmoney.
(2)Heneverstudies.Instead,heplaysalldaylong.
(3)Thestudentsdidn'tsmile.Instead,eachofthemmadeaface.
13.taste/smell/sound/look/feel等感官动词的用法。
其后必须加形容词。
(1)Theflowerssmellverynice.
(2)Theoldwomanlookedveryworried.
(3)Theclothfeelsverysoft.
(4)ThefoodtastessodeliciousthatIcantwaitanylonger.
14.Noneofyouwatchedcarefullyenough.
none为不定代词,意思是“没有一个人或物”。
none做主语指代可数名词时,其谓语动词单复数形式都可以,但是当它指代不可数名词时,其谓语动词为单数第三人称形式。
none常与表示范围的of介词短语连用并表示全部否定。
(1)Noneofthemhas/havegotabike.
(2)Noneofusis/areafraidoftheghosts.
(3)Noneofthismoneyismine.
(4)---Howmanyapplesdoyouhave?
---None.
none/noone的比较
none既可以指代人也可以指代物,强调数量,可以用来回答howmany开头的问句。
而用法与意思基本相同的noone(nobody)只能指代人,它们不强调数量,可以用来回答who开头的问句。
(1)----Howmanypeoplecanyouseeinthepicture?
-----None.(一个也没有)
(2)---Whoisintheclassroom?
----Noone.(Nobody)(没有人)
15.enough的用法
enough+noun./adj./adv+enough
enough可指代可数名词或不可数名词,其谓语动词形式可依据它指代的名词的数来定。
(1)Enoughhasbeensaidonthissubject.在这一点上说的已经够多的了。
(2)Enoughweresenttohim.Henolongerwantedtohavesuchbooks.
(3)----Wouldyoupleasehavesomemore?
----No,thanks.I'vehadenough.
(4)Iamafraidwehaven'tgotenoughtimetodothework.
(5)You'reoldenoughtolearntodressyourself.
