英语中主谓一致关系是个既重要、又复杂且难掌握的问题,在各种入学试题及水平测试题中对此问题常有涉及。在人称和数上谓语动词和主语必须保持一致,决定这一关系的原则总起来说有三,即:A、语法一致;B、概念一致;C、邻近一致。语法一致...英语中主谓一致关系是个既重要、又复杂且难掌握的问题,在各种入学试题及水平测试题中对此问题常有涉及。在人称和数上谓语动词和主语必须保持一致,决定这一关系的原则总起来说有三,即:A、语法一致;B、概念一致;C、邻近一致。语法一致的原则是指谓语动词必须与主语的数保持一致。例如:Children always enjoy their birthday。(句中主语Children是复数,故谓语动词用复数。)展开更多
(一) 贸易的对象就是货物,就是商品。只要我们一打开英语的贸易资料,就有许多表示货物的名词如goods,commodity,……映入眼帘,不一而足。那么,英语中到底有哪些名词常用于表示货物?它们的使用特点又如何?这里谈一点个人的粗浅认识。 (1)...(一) 贸易的对象就是货物,就是商品。只要我们一打开英语的贸易资料,就有许多表示货物的名词如goods,commodity,……映入眼帘,不一而足。那么,英语中到底有哪些名词常用于表示货物?它们的使用特点又如何?这里谈一点个人的粗浅认识。 (1)goods:这是使用最广泛的名词,如:We handle a variety of goods。(我们经营各种商品。)它不使用单数形式,也不可与数词连用。如不能说three goods,但可说three pieces of goods。展开更多
