        1. 【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

          【答案】A

          【解析】

          句意:高老師教我們英語兩年了。她從兩年前到這來的。

          考查現(xiàn)在完成時。For+一段時間,表示持續(xù)了一段時間;since+時間點,表示自從何時開始。第一個空后是two years兩年,是一段時間,所以用for;第二個空后two years ago兩年前,是時間點,所以用since,故選A
