在我们大甩卖之际购买衣服吧！（1）此句是祈使句，没有主语，以动词原形开头。（2）at“在”，是介词，后接名词、代词和数词。（3）sale是sell的名词形式，意为“买卖；销售”。sale还可作“大甩卖、清仓大减价”讲。eg：asaleprice廉价forsale待售（的）onsale出售；特价销售（4）clothes“衣服，服装”，常用复数形式，不用单数。Grammar2.Wesellallourclothesatverygoodprices.

我们以很优惠的价格售卖所有的衣服。（1）price是名词，意为“价格；价钱”。eg：What'sthepriceofthisbook?这本书的价格是多少。（2）atverygoodprice意为“以很低的价格”。与atalowprice意思相同。eg：Wesellthesebooksatverygoodprices.我们以很低的价格卖这些书。

3.Doyouneedtrousers?你需要裤子吗？（1）在这句话中，need是实义动词，意为“需要”。need常用于以下句式：

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

need+todosth.表示“需要做某事”。这时need的主语是人。eg：Youneedtoputonmoreclothes.你需要多穿衣服。（2）need+doingsth.表示“需要做某事”，含有被动意义且need的主语是物。eg：Thebikeneedsmending.这辆自行车需要被修理。4.Forboys,wehaveblacktrousersforonly＄22.

对男孩子，我们有黑色的长裤，只卖22美元。介词for有很多种意思，这句话中就有两个for,但它们的意思却各不相同。（1）forboys意为“对于男孩；适于男孩的”，for在此处意为“适合于”。eg：Theseareclothesforchildren.这些衣服是适合小孩子穿的。（2）foronly＄22意为“只卖22美元”。for在此处意为“以······为代价；以······交换”。eg：Hesoldhiscarfor500dollars.他以500美元买出他的车。Thepriceissohigh.
