either

常用用法

either作代詞時,意為“(二者之中)任何一個”,在句中作主語或賓語,表示單數(shù)概念; 作主語時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,但意義明確時可省略of短語。

這三個詞都表示“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,有強調(diào)意味,位于主謂語之間,即實義動詞之前,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.他是個教師,也是個作家。
