10、nlessyourteachertellsyoutodo。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) Youcangowithmeifyoudliketo。(2) Youmaystayathomeifyouwantto。(3) Idontwanttogothere，buthesgoingto。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、

13、with表示“具有，带有”(1) Chinaisacountrywithasplendidcultureandalonghistoryo(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) WhydidntyoudoasIasked?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

17、hismoneyismine。(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+enoughenough可指代
