考向1need用作实义动词，意为“需要”，其后可接名词、代词或动词不定式作宾语，此时need有人称、数和时态的变化，句型变化时需借助助动词。e.g.Weneedmuchmoneynow.我们现在需要很多钱。-Doesheneedanyhelp?他需要帮助吗？-Yes,hedoes./No,hedoesn’t.是的，他需要。/不，他不需要。拓展:need也可用作情态动词，意为“需要”，其用法:(1)后接动词原形;(2)多用于疑问句或否定句中，否定形式为needn’t;(3)疑问形式需将need提至句首:(4)回答由need,must引导的一般疑问句时，肯定回答用must,否定回答用needn’t或don’thaveto。e.g.-MustIcleantheroomnow?我现在必须打扫房间吗?-No,youneedn’t.Youcandoitlater.不，你不必。你可以稍后打扫。<考题11>Wehaveonlyoneapple,soyouneedto__________(share)itwithyourbrother.3.l’lltake

it.考点12I'll的用法考向I’ll是Iwill的缩写形式。“will+动词原形”表示“将要..”，常用来表示将要发生的动作。e.g.I'llplayfootball.我将要踢足球。考点13,take/terk/v.买下;拿;取考向1take意为“买下”,相当于buy或get。在口语中,当顾客选定了物品要买时，通常说“I'lltakeit/them.”,而不说“I'llbuyit/them.”。点拨:考查交际用语。Itlooksbad它看起来很糟糕;It’stooexpensive它太贵了;Idon'tlikeit我不喜欢它;I’lltakeit我买下了。根据“Great.”可知顾客很满意，即买下了。4.Twodollarsforonepairandthreedollarsfortwopairs.考点14,for的用法考向介词for用来表示物品的价格，用法为:价格+for+具体物品e.g.It’s30yuanforthisbook.这本书30元。Howmuchisitfortwo?(买)两个多少钱?考点15(高频)pair/pea(r)/,/per/n.一双;一对考向相当于汉语中的量词,常构成apairof短语。其后的名词通常是由两个相同部分组成的物品，只用复数形式。e.g.Mysisterhasanewpairofshoes.我姐姐有一双新鞋。拓展:(1)a/thepairof短语在句子中作主语时，句子的谓语动词用单数形式，即与pair的数保持一致。e.g.Thepairofshoesisverynice.(2)...pairsof+复数名词”作主语时，谓语动词要与pairs的数保持一致，谓语动词用复数形式。e.g.Therearethreepairsofglovesinthebox,盒子里有三双手套。<考题17>Thispairofsocks___________soft.I’lltake_________.A.feel;itB.feels;it

C.feels;them

点拨:用语法判定法解题。"Thispairof+复数名词“作主语时，谓语动词与pair保持一致，故第一个空处应用第三人称单数形式feels;
