在我們大甩賣之際購買衣服吧?。?）此句是祈使句，沒有主語，以動詞原形開頭。（2）at“在”，是介詞，后接名詞、代詞和數(shù)詞。（3）sale是sell的名詞形式，意為“買賣；銷售”。sale還可作“大甩賣、清倉大減價”講。eg：asaleprice廉價forsale待售（的）onsale出售；特價銷售（4）clothes“衣服，服裝”，常用復數(shù)形式，不用單數(shù)。Grammar2.Wesellallourclothesatverygoodprices.

我們以很優(yōu)惠的價格售賣所有的衣服。（1）price是名詞，意為“價格；價錢”。eg：What'sthepriceofthisbook?這本書的價格是多少。（2）atverygoodprice意為“以很低的價格”。與atalowprice意思相同。eg：Wesellthesebooksatverygoodprices.我們以很低的價格賣這些書。

3.Doyouneedtrousers?你需要褲子嗎？（1）在這句話中，need是實義動詞，意為“需要”。need常用于以下句式：

need+物，表示“需要某物”。eg：IneedalotofEnglishbooks.我需要很多英語書。

need+todosth.表示“需要做某事”。這時need的主語是人。eg：Youneedtoputonmoreclothes.你需要多穿衣服。（2）need+doingsth.表示“需要做某事”，含有被動意義且need的主語是物。eg：Thebikeneedsmending.這輛自行車需要被修理。4.Forboys,wehaveblacktrousersforonly＄22.

對男孩子，我們有黑色的長褲，只賣22美元。介詞for有很多種意思，這句話中就有兩個for,但它們的意思卻各不相同。（1）forboys意為“對于男孩；適于男孩的”，for在此處意為“適合于”。eg：Theseareclothesforchildren.這些衣服是適合小孩子穿的。（2）foronly＄22意為“只賣22美元”。for在此處意為“以······為代價；以······交換”。eg：Hesoldhiscarfor500dollars.他以500美元買出他的車。Thepriceissohigh.
