1. "both" 与 "as well" 的语法功能
"both" 是 并列连词 或 限定词,用于强调 两者都,需搭配 "and" 构成固定结构(如 both...and...)。
"as well" 是 副词短语,意为 “也”,通常置于句末,不连接并列成分(如 I like coffee, and tea as well)。
若需强调 两者兼具,用 "both...and...":
She is both smart and kind.(她既聪明又善良。)
若需补充 “也”,单独用 "as well":
She is smart, and kind as well.(她聪明,人也善良。)
as well as 连接并列成分,侧重前者 *She sings as well as dances.
as well 句末补充“也” *He came, and his brother as well.
关于 "both...as well as..." 的连用问题
"The study defined heat waves as both a period of at least two consecutive days of abnormally high temperatures as well as any time when officials issued heat warnings."
"both...as well as..." 在此句中 通过 "as well as" 替代了 "and",形成 非正式但可接受的并列结构。
外刊中的常见用法,"as well as" 的灵活性:
在学术或新闻英语中,"as well as" 可替代 "and",但需注意 逻辑侧重。
标准结构:Heatwaves are both prolonged heat and official warnings.
外刊变体:Heatwaves are both prolonged heat as well as official warnings.(更口语化)
"both...as well as..." 在外刊中可接受,但属于变体。
正式写作中,建议优先使用 "both...and..." 以确保语法严谨性。
