As far as I know, he is seldom, ______, absent from school. A．if any B．if so C．if ever D．if not

Answer 1

C

试题分析：考查状语从句的省略。A如果有一些；B如果这样；C如果曾经有过；D如果不；句意：据我所知，如果从句有过，他也很少会缺席。If ever="If" he has ever been absent from school。如果他参加缺席上学。 点评：当状语从句的主语与主句的主语一致，且状语从句中有系动词be的时候，可以把状语从句的主语和be动词一起省略。如果状语从句中有it is的时候，it is 也可以省略。
