both and用法
both…and…,其意为“…和…都”、“不但…而且…”、“既…又…”。
1、意为“…和…都”
作为关联并列连词,它通常应连接两个相同性质的句子成分,但有时后一成分可能省略与前一成分相同的词。另外,若连接两个成分作主语时,谓语要用复数:
举例:Both she and Sophia were pleased with the girl。她和索菲娅都喜欢这姑娘
2、意为“不但…而且…”
举例:She both speaks and writes Japanese。 她不仅会说日语,而且还会写。
3、意为“既……又……,和……”
连接的两个成分必须在形式、时态、词性等方面完全一致,可以是形容词、名词、动词和句子等,一般语法结构是:
both+形容词+and+形容词
both+名词+and+名词
both+句子+and+句子
举例:She's both ptetty and clever。她既漂亮又聪明。
