題組24(介詞+when/where) 1. The book was written in 1946, __ the education system has witnessed great changes. (2007,山東) A.when B.during which C. since then D. since when 句意:這本書寫于1946年,從那時起,教育系統見證了巨大的變化。分析:①不選since then,因為,兩句中間有逗號,所以,前后兩句是主從復合句,后句是從句,從句要用引導詞開頭。②since when=since in 1946,選D。 2. I have no idea ____ the journalist could have got his information from. (2011,上海春) A. that B. why C. when D. where 分析:where…from=from where,選D。 3. Jane is back in May, by____ the new house should be finished.(2008,非延考區) A. which B. that C. whom D. when 句意:簡五月份回來,屆時新房子應該完工。分析:因為前邊有May,因此容易誤選A。其實,此時的先行詞應是前面的整個句子,強調的是“回來這一時間”。選D。 4.—____ when has the country been open to international trade? (2007,陜西) —1978, I suppose. A. Since B. In C. From D. After 句意:這個國家從什么時候起進行國際貿易的?分析:since 意為“自從”,常與現在完成時連用,表示動作從某個時候開始,一直延續到現在。選A。
