unless,assoonas和so...that...unless是连词,意为“除非；如果不”,相当于“if...not...”,用来引导条件状语从句。如：Youwon’tcatchthebusunlessyourun.UnlessDadagrees,Ican’tgotothemovies.assoonas是连词,意为“一……就……”,用来引导时间状语从句。如：Mybrotherwilllookforajobassoonasheleavesschool.Youmaydrinkwaterassoonasyoureachhome.注意：通常情况下,在含有unless和assoonas的复合句中,如果主句用一般将来时、主句为祈使句或主句的谓语部分含有情态动词,那么unless和assoonas引导的从句常用一般现在时。so...that...是连词,意为“如此……以至于……”,用来引导结果状语从句,so修饰形容词或副词。常见结构有“so+形容词/副词+that从句”和“so+形容词+a(n)+可数名词的单数形式+that从句”等。如：Themanspokesofastthatwecouldhardlyfollowhim.Andyissohonestamanthatweallbelievehim.1.so...that...结构常常可与too...to...结构,...enoughto...结构进行转换，但是如果that引导的从句中的主语和主句中的主语不同，转化为too...to...结构或...enoughto...结构时要用for引出不定式的逻辑主语。如：Mycousinissoyoungthathecan’tgotoschool.→Mycousinistooyoungtogotoschool.→Mycousinisnotoldenoughtogotoschool.Shewalkedsoquicklythatwecouldn’tcatchupwithher.→Shewalkedtooquicklyforustocatchupwith.→Shedidn’twalkslowlyenoughforustocatchupwith.2.such...that...也表示“如此……以至于……”，用来引导结果状语从句，可与so...that...结构进行转换。常见结构有“such+a(n)+形容词+可数名词的单数形式+that从句”和“such+形容词+可数名词的复数形式/不可数名词+that从句”等。如：ItwassuchaninterestingfilmthatIwenttoseeitseveraltimes.→ItwassointerestinganfilmthatIwenttoseeitseveraltimes.Theyaresuchcleverboysthateveryonelikesthem.→Theboysaresocleverthateveryonelikesthem.单项选择。1.—Howlongwillyoustayhere?—______Ifinishmyhomework,I’llgobackhome.A.AssoonasB.WhileC.UnlessA2.We’llhaveapicnicneartherivertomorrow______itrainsheavily.A.untilB.ifC.unlessD.when3.TherearefewerandfewertigersinIndia.Thesituationwillcontinue______humansstophuntingthemfortheirfurandbones.A.ifB.unlessC.becauseD.sinceCB4.Ithinkyoushouldcomplain,______,ofcourse,youarehappywiththesituation.A.unlessB.howeverC.untilD.thoughA5.—YourgrandfatheroftendoesTaiChiinthepark.—Yeah,______badweatherstopshim.A.whenB.sinceC.unlessD.becauseC6.Iwillbeveryhappy______youcometomyparty.A.ifB.thoughC.or7.Itis______abeautifulgarden______weliketoplayinit.A.so;thatB.such;thatC.too;toD.very;thatAB8.Bobisalwayspolitetoeveryone,andheis______lovely______allofuslikehimverymuch.A.too...toB.neither...norC.so...thatD.such...thatC9.Lilywas______hungry______sheatethreehamburgersinonego.A.too;toB.so;thatC.enough;thatB10.China’sGotTalentis______interesting______manypeoplelikewatchingit.A.too;toB.enough;toC.so;thatD.such;thatC11.—Didyouwatchthesoccergamelastnight?Ourschoolteamwonthegameinthelastminute!—Yes.Iwas______excited______Icouldnotfallasleep.A.as;asB.so;asC.too;toD.so;thatDI.根据句意及括号内所给单词的提示填空。1.Themusiccangivemeafeelingof__________(excite)whenIfeelsad.2.BeforeHenrygot________(marry),healwayswenttothemoviesonweekends.3.Inmyopinion,________(wife)andhusbandsmustbelieveineachother.marriedexcitementwives4.Iwouldliketobeazoo_______(keep)whenIgrowup.Ilikelookingafteranimals.5.Wearingsunglassesprovides__________(protect)foroureyes.6.Amanhadaheart________(ill)andwassenttoahospitalthismorning.7.Theparkisbeautifulandattractsmany________(tour)everyyear.8.Itwasverycold,soTimworeoneofthe________(thick)coatstokeepwarm.thickestkeeperprotectionillnesstouristsII.根据括号内的要求完成下列各题，每空一词(含缩略形式)。1.Thewallisabout600kilometerslong.(对划线部分提问)____________isthewall?2.Thatmountainisabout456.5metershigh.(对划线部分提问)_____________isthatmountain?HowlongHowhigh3.Sandyrantooslowlytocatchthebus.(改为同义句)Sandyran_____slowly_______shecouldn’tcatchthebus.4.Iwon’tgofishingunlessitisfinetomorrow.(改为同义句)Iwon’tgofishing____it______finetomorrow.ifisn'tsothat5.Danielisthetallestinhisclass.(改为同义句)Danielis___________________________studentinhisclass.6.Eventhoughhamburgersareunhealthy,manychildrenlikeeatingthem.(改为同义句)____________hamburgersareunhealthy,manychildrenlikeeatingthem.EveniftallerthananyotherIII.根据汉语意思完成英语句子,每空一词。1.约翰出生时是一个残疾的男孩。真可怜！Johnwasadisabledboy____________.Whatapoorboy!2.请慢点跑，否则你会绊倒。Pleaserunslowly,oryouwill____________.fallatbirthover3.据我所知，他到镇上去了。_____________________,hehasgonetothetown.4.戴尔邀请了大约20个人参加他的生日聚会。Daleinvitedtwentypeople________tohisbirthdayparty.5.有点儿冷，明妮，请关上窗户。It’s_______________cold,sopleaseclosethewindow,Minnie.alittlebitAsfarasIknoworso6.到休息的时间了，你可以随便做你喜欢的事情了。It’stimetohavearestandyoucan____________todowhateveryoulike.7.因为房间里有很多人，所以我很难吸入新鲜空气。It’shardformeto_________freshairbecausetherearetoomanypeopleintheroom.takeinfreefeel8.这是如此漂亮的一座花园，以至于我认为大家会喜欢上它的。It’ssuchabeautifulgardenthatIthinkeveryonewill_____________________it.fallinlovewith
