9. A 從后 半句中 的 and now 可以看出,“李小姐在公司做了 五 年秘書”這件事情發(fā)生在過(guò)去,現(xiàn)在她已經(jīng)不是秘書了。答句是陳述過(guò)去的一個(gè)事實(shí), 所以 用一般過(guò)去時(shí)。根據(jù)語(yǔ)境可知錯(cuò)誤已經(jīng)造成,即已經(jīng)是過(guò)去的事實(shí)了;而“建議”是在錯(cuò)誤出現(xiàn)之前提出的,所以建議應(yīng)該是“過(guò)去的過(guò)去”。 19.

D 句意:“多么嚴(yán)重的錯(cuò)誤!”“是的。根據(jù)句子的意思, 空格處 表示發(fā)生在過(guò)去的動(dòng)作對(duì)現(xiàn)在所產(chǎn)生的影響,所以 此處應(yīng) 用現(xiàn)在完成時(shí)。上句的時(shí)態(tài)是一般過(guò)去時(shí),所以 本句 要用過(guò)去完成時(shí),表示動(dòng)作發(fā)生在 was very nervous 之前 。 5. B “ 在波士頓生活四年”是純粹發(fā)生在過(guò)去的事情,且由句意知該動(dòng)作并沒有持續(xù)到現(xiàn)在,故選 B。xxamp。福建高考 ) Last month, the Japanese government expressed their thanks for the aid they _______ from China.
