拓展提升1.Thetemperaturecanbeaslowas-15℃.

as...as意為“和……一樣”，表示同級的比較。使用時要注意第一個as為副詞，第二個as為連詞。其基本結(jié)構(gòu)為：as+adj./adv.+as。例如：1)Thisfilmisasinterestingasthatone.2)Yourpenwritesassmoothlyas

mine.其否定式為notas/so+adj./adv.+as。例如：Thisdictionaryisnotas/sousefulasyouthink.這本字典不如你想象的那樣有用。若有修飾成分，如twice,threetimes,half,aquarter等，則須置于第一個as之前。例如：Yourbagistwiceasexpensiveasmine.你的袋子比我的貴一倍。2.Weprobablywon’tseeanyflowersuntilMayorJune!

until“直到”，表示某一種行為一直持續(xù)到某一時間。用在肯定句中，句子的謂語動詞必須是可延續(xù)的。not...until...“直到……才......”表示直到某一時間，某一行為才發(fā)生，之前該行為并沒有發(fā)生。在否定句中，主句中的謂語可延續(xù)也可短暫。1)IstudiedEnglishuntil9o’clocklastnight.

我咋晚學(xué)英語一直學(xué)到9點鐘。(表示9點前一直在學(xué))

2)IdidnotstudyEnglishuntil9o’clocklastnight.

我咋晚直到9點鐘才學(xué)英語。(表示9點才開始學(xué))

3)Iwaitedforfivehoursuntilitwasdark.Ihadtogiveitup.

4)Ididn’tgotosleepuntil11o’clock.notuntil還可以用于強調(diào)句中，也可以放在句首，句子要采用部分倒裝。

5)Itwasnotuntilhecamebackthat

Iwenttosleep

NotuntilhecamebackdidIgotosleep.

3.Wehadtowearourjacketsandboots…

haveto是一個比較特殊的情態(tài)短語，雖然也具有情態(tài)動詞的功能，但卻與其他的情態(tài)動詞不同。它有人稱、數(shù)和時態(tài)的變化，其否定式和疑問式的構(gòu)成方式也與情態(tài)動詞不一樣。同學(xué)們在使用haveto時必須弄清它的真面目，否則容易出錯。

1).haveto與其他情態(tài)動詞一樣也是后接動詞原形，表示外界的強制作用，強調(diào)被迫性。含有不情愿的色彩，常譯為“必須，不得不”。

2).haveto可用于多種時態(tài)，而且不同時態(tài)使用不同的形式：一般現(xiàn)在時中，主語為第三人稱單數(shù)時用hasto;一般過去時中，用hadto,haveto還可以用在其他的情態(tài)動詞之后。例如：

Ihavetodosomewashing.

Shehastolookafterherlittlesister.

Ihadtodomyhomeworklastnight.

IthinkhemayhavetohelphisDadinthegarden.

3).haveto

的否定式和疑問式一般要借用助動詞do的適當(dāng)形式構(gòu)成。haveto的否定式是don’thaveto；hasto的否定式是doesn’thaveto；hadto的否定式是didn’thaveto。haveto的疑問式同樣也借用助動詞do的相應(yīng)形式構(gòu)成。例如：

Hedoesn’thavetodothehomeworknow.

—DoIhavetogotherenow?

—Yes,youdo.(No,youdon’thaveto.)

Wedidn’thavetoanswerthequestionyesterday.

【辨析】haveto,musthaveto與must均有“必須”的意思,但must強調(diào)人主觀認(rèn)為必須做某事,而haveto強調(diào)客觀情況迫使人不得不做某事;且must只用于一般現(xiàn)在時中,沒有人稱和數(shù)的變化,而haveto可用于多種時態(tài)中,并且有人稱和數(shù)的變化。Wemustgotoschoolontime.Shehastolookafterherbabyathome.當(dāng)堂檢測We______listentotheteacherscarefully.(必須)
