( ), I must do another experiment in the laboratory. A. Be it ever so late B. It is ever so late C. It be ever so late D. So late it be ever 答案選A請告訴我理由吧，謝謝

熱心網友

選A,用ever在句首時需要倒裝，將謂語助動詞Be提前,相當于Though it is ever so late.

熱心網友

1、前后主語必須一致，B，C均排除2、省略though的倒裝句

熱心網友

有ever時需要倒裝，倒裝時需將謂語助動詞提前倒裝

熱心網友

這是個倒裝句=though it is ever so late
