  值得英語進(jìn)修者注重的是

 ?、疟M管be+介詞短語能暗示"正在進(jìn)行"這一意義,但它和be+此刻分詞所暗示的語僧衣義是有分歧的。前者著重事物所處的狀況,著重于靜態(tài);后者著重事物的動(dòng)態(tài),集中暗示事物的動(dòng)感。

 ?、?絕大部門這類結(jié)構(gòu),其名詞前都沒有冠詞,假如加一冠詞,意義將迥然不同。如:The Conservative Party is in office.保守黨在執(zhí)政。The principal is now in the office.校長(zhǎng)此刻在辦公室。英語進(jìn)修者對(duì)上述分歧決不成失蹤以輕心。
