可以用“Whatabout/Howabout

…?”来提出建议，about后可接名词或动词-ing形式。如：Whatabout/Howaboutadrink?喝一杯怎样？Whataboutwritingbacktohimaboutit?要不就这件事给他回一封信怎样？D.可以用“Whynot

…?”来提出建议，表示“何不……？”，not后面接动词原形。Whynot…?实际是Whydon'twe/you…?的简略形式。如：Whynotmeetattheschoolgateateight?

何不在八点的时候在校门口集合？Whydon’twestayhereanotherday?

我们为什么不在这儿再待一天呢？E.可以用Wouldyoulike…?来提出建议，意思是“你想要吗?”，wouldlike后可接名词或不定式。如：Wouldyoulikeacupofcoffee?你想来杯咖啡吗？Wouldyouliketoplaywithme?

你愿意和我一起玩吗？如果我们要说“去散散步，好吗？”，英语有几种表达方式?Let’sgoforawalk,shallwe?Whataboutgoingforawalk?Howaboutgoingforawalk?Whynotgoforawalk?Wouldyouliketogoforawalk?Whatdoyouthinkofgoingforawalk?“although/though”although的意思是“尽管，虽然”，用来引导让步状语从句，在一般情况下可以和though互换，但though比较口语化，而although较为正式，另外although的语气比though重。当although/though引导的从句放在句首时，主从句之间要用逗号隔开。AlthoughIgavehimsomeadvice,hedidn’ttakethem.虽然我给了他一些建议，但他没有采纳。Althoughit’sraining,theyarestillworkinginthefield.虽然在下雨，但他们仍在地里干活。Thoughhetriedhard,hewasnotsuccessful.虽然他尽力而为，但他没有成功。Although/Thoughhewastired,hekeptonworking.虽然他已经累了，但仍然继续工作。注意：although和though都不能和but在一个句子里连用。“sothat”﹠“so…

that…”

sothat

用来引导目的状语从句，意思为“以便，为了”，从句中常用can(could)，will(would)，may(might)等情态动词。so...that...用来引导结果状语从句。Hegotupearlythismorningsothathecouldcatchtheearlybus.今天早上他早起，以便能赶上早班车。Hegotupsoearlythismorningthathecaughttheearlybus.今天早上他起得非常早，这样就赶上了早班车。翻译下面的句子。1.他跑得很快，我们跟不上他。2.我们把灯打开，以便看看它是什么。Heransoquicklythatwecouldn’tcatchupwithhim.Weturnedonthelightsothatwemightseewhatitwas.until可用作时间连词，用来谈论事情发生的时间。until表示“直到……为止”。用来引导时间状语从句，在句中可以放在主句之前或之后。“until”Keepstraighton

until

yougettothechurch.一直朝前走就走到教堂了。Thehotweatherlasted

until

September.

炎热的天气持续到九月。Ididn’twakeup

until

Iheardthealarmclock.

直到听到闹钟的铃声我才醒来。A.在引导时间状语从句时，适合“主将从现”原则，

即主句如用一般将来时，

从句一般用一般现在时。同步推之，如果主句用过去将来时，从句一般用一般过去时。[注意]B.until除了可用作连词，还可用作介词，其后可接名词、代词或动名词。如:Wedidnotnoticethismatteruntilyesterday.直到昨天我们才注意到这件事。C.till与until为同义词，

都可表示“直到……为止”，

但如果要表示“直到……才”，

一般用not...until结构，

且till引导的时间状语从句通常只能放在主句之后。直到亲眼所见，她才相信它。2.直到她哭了，他才放弃和她吵。Shewon’tbelieveituntilsheseesitwithherowneyes.Hedidn’tgiveupquarrellingwithheruntilshecried.3.直到他写完一篇800字的文章，他才停下来休息。4.我们一直走到河边为止。5.他到十岁才会游泳。Wewalkeduntilwegottotheriverside.Hecouldn’tswimuntilhewasten.Hedidn’tstoptohavearestuntilhefinishedwritingan800-wordarticle.Fillintheblankswithalthough,so
