(要我帮忙吗？) May I help you?(要我帮忙吗？) 后两句比Can I help you? 在语气上更加客气和委婉。 回答可用Yes， please. I want … No, thanks. I need a sweater for school. need 此处做实义动词，“需要”。后面可以跟名词、代词或动词不定式（to do）作宾语。 need sth. 需要某物 need to do sth. 需要做某事 I need an eraser.我需要一块橡皮。 I need to do my homework. 我需要做家庭作业。 need也可作情态动词，意为“需要”。此时need没有人称和数的变化，其后跟动词时要用动词原形，变否定句时，要在need后加not;变疑问句时，要把need提到主语前。 You needn’t do it again. Need he do his homework first? How about this one? 这件怎么样？ one代词，此处用于代指上文提到的sweater。 one: 指代“同名异物”，即指代与前面事物同属一类的事物，并不是指同一个事物。如果指代同类事物中的一些，要用ones。 This apple is small. Please give me a big one.
