either

常用用法

either作代詞時(shí),意為“(二者之中)任何一個(gè)”,在句中作主語或賓語,表示單數(shù)概念; 作主語時(shí)謂語動詞一般用單數(shù)形式,但在否定句中常用復(fù)數(shù)形式。either可單獨(dú)用,也可和of連用, of后跟復(fù)數(shù)名詞或復(fù)數(shù)代詞,但意義明確時(shí)可省略of短語。

這三個(gè)詞都表示“兩者…”。neither表示“兩者都不…”,常與單數(shù)謂語動詞搭配; both表示“兩者都…”,常與復(fù)數(shù)謂語動詞搭配; either表示“兩者之一”,常與單數(shù)謂語動詞搭配。

這組詞(組)都有“也,此外,還有”的意思。其區(qū)別是：
also一般用于肯定句,有強(qiáng)調(diào)意味,位于主謂語之間,即實(shí)義動詞之前,助動詞之后; too只用于肯定句中,一般位于句末,比also更口語化; either一般只用于否定句,多位于句末; as well和too一樣多用于口語,放在句末; besides與moreover詞義基本相同,但moreover后面所敘述的,通常比前面所敘述更為重要或更深入一步,在詞序方面, moreover往往用于句首,另外, moreover是較為正式的用語。例如:
He also asked to go.他也要去。
I can also do it.我也能干那個(gè)活。
English is not easy, and French is not easy either.英語不容易,法語也不容易。
He is a teacher, and a writer as well.他是個(gè)教師,也是個(gè)作家。
I don't like those shoes; besides, they're too expensive.那雙鞋我不喜歡,而且也太貴。
I don't like skating; moreover, the ice is too thin.我不想去溜冰,再說冰層也太薄。
The Opposition have consistently accused the Government of corruption.Moreover, they have named names.反對黨一直在指責(zé)政府腐敗,而且是指名道姓的。
