(2)Onceyourealizeit,youwillstudyhard. (3)Onceseen,itcanneverbeforgotten.只要見過一次就難以忘懷。 注意once一般和現(xiàn)在時連用。 4.unless是連詞，相當于ifnot (1)Hewillnoteunlesshishomeworkisfinished.=Hewilleifhishomeworkisfinished. (2)Youwillbeintroubleunlessyoufollowmyinstruction.=Youwillnotintroubleifyoufollowmyinstruction. unless和notuntil的區(qū)別 unless引導從句時多強調條件，而notuntil句型則強調時間。Unless連接的主從句的時態(tài)一般是主句是將來時而從句現(xiàn)在時。notuntil連接的主從句中可以使用多種時態(tài)。 比較： (1)Youwillfailintheexamunlessyoulistentotheteachercarefullyinclass. (2)WewontstartuntilBobes. (3)Hedidntfindoutwhathadhappeneduntilhiswifetoldhimaboutit. 5.Donttouchanythingunlessyourteachertellsyoutodo. 在此句末的to后省略了touch。在英語里，有些動詞像hope,like,want,try,need,助動詞如beableto.,begoingto之后，為了避免前后重復，往往只用一個to代表動詞不定式。 (1)Youcangowithmeifyoudliketo. (2)Youmaystayathomeifyouwantto. (3)Idontwanttogothere,buthesgoingto. 6.Whataboutwhenweleave? Whatabout?與Howabout?可以用來詢問消息、提出建議或征詢意見，其后可接名詞、代詞、動名詞、副詞（如next）和狀語從句等。 (1)Imready.Whataboutyou? (2)Whataboutplayingfootball? (3)Whatabouttodaysmatch? 7.makesure后跟了一個省略了that的從句。當表示“弄確實、使確定”意思時，常用在祈使句中，其后的從句里要用一般現(xiàn)在時。當makesure表示“認為、確信”的意思時，其后的從句時態(tài)可視情況而定。 (1)Makesure(that)youeearlytomorrow. (2)Makesure(that)yourroomisclean. (3)Wemadesureyouwerenotingtoday.我們認為你今天一定不來了。 8.turnoff其反義詞是“turnon turnup(開大)其反義詞是turndown(關小本文,摘自教育資源網(wǎng)WWw.cHINEseJY.Com) 9.attheendof/intheend attheendof意為“在末，在盡頭”，既可以表示時間的概念也可以表示空間的概念。而intheend只能表示時間的概念,其后不能接of短語，相當于finally,atlast.

(2)Noneofusis/areafraidoftheghosts. (3)Noneofthismoneyismine. (4)-Howmanyapplesdoyouhave?-None. none/noone的比較 none既可以指代人也可以指代物，強調數(shù)量，可以用來回答howmany開頭的問句。而用法與意思基本相同的noone(nobody)只能指代人，它們不強調數(shù)量，可以用來回答who開頭的問句。 (1)-Howmanypeoplecanyouseeinthepicture?-None.(一個也沒有) (2)-Whoisintheclassroom?-Noone.(Nobody)（沒有人） 15.enough的用法 enough+noun./adj./adv+enough enough可指代可數(shù)名詞或不可數(shù)名詞，其謂語動詞形式可依據(jù)它指代的名詞的數(shù)來定。 (1)Enoughhasbeensaidonthissubject.在這一點上說的已經(jīng)夠多的了。 (2)Enoughweresenttohim.Henolongerwantedtohavesuchbooks.
