此类词作主语时，谓语动词用复数形式；但与apairof…（一双、一对或一副）连用时，谓语动词用单数形式。如：Myshoes_____underthebed.我的鞋在床下了。Thatpairofshorts____Jack’s.那条短裤子是杰克的。

Thesetwopairsofsocks______Lisa’s.这两双袜子是丽莎的。apairof/twopairsofsocks/shorts(也可以用some,many,these,those等词修饰)scissors

shortstrousersglasseschopsticksareisare错误：athispairof5.Ineedasweaterforschool.我需要一件毛衣上学穿。（P38）

need是实义动词，意为“需要”。常用于以下句式中：1)sb+need+sth.，“需要某物”。如：我需要一些衬衫。

Ineedsomeshirts.2)sb+need+todosth.“需要做某事”，这时need的主语是“人”。如：我需要洗这件衬衫。Ineedtowashthisshirt.3)sthneed+doing.表示“某事需要做”，这时need的主语是“物”。sthneed+tobedone如：这件衬衫需要洗了。Theshirtneedswashing.Theshirtneedstobewashed.howmuchUn.Howmuch+Un+一般疑问句？howmanyCpl.Howmany+cpl+一般疑问句?【语法·强化】(
