Question

【題目】Miss Gao has taught us English ______ two years. She has been here ______. two years ago.

A.for; sinceB.since; forC.for; forD.since; since

Answer 1

【答案】A

【解析】

句意：高老師教我們英語(yǔ)兩年了。她從兩年前到這來(lái)的。

考查現(xiàn)在完成時(shí)。For+一段時(shí)間，表示持續(xù)了一段時(shí)間；since+時(shí)間點(diǎn)，表示自從何時(shí)開(kāi)始。第一個(gè)空后是two years兩年，是一段時(shí)間，所以用for；第二個(gè)空后two years ago兩年前，是時(shí)間點(diǎn)，所以用since，故選A。
