如果對單項選擇題的選項感到困惑,而又難以突破時,我們可以換一個角度,從“假設(shè)某項成立”出發(fā),結(jié)合題意,進行分析推理,從而打開解題思路,變難為易。
4. It was 3 o’clock _____ they arrived at the station.
A. that B. when C. after D. before
該題正確答案為B. 但很多學(xué)生認為這是強調(diào)句而選A. 現(xiàn)在假設(shè)A選項成立,即:It was 3 o’clock that they arrived at the station. 根據(jù)強調(diào)句的驗證方法,去掉it was…that… 即變?yōu)椋? o’clock they arrived at the station. 這顯然是錯的。因為3 o’clock前缺少介詞at 故假設(shè)不成立。it在此不屬于強調(diào)結(jié)構(gòu),而是指代時間的無人稱代詞。而選B則是由when引導(dǎo)的時間狀語從句。意思為“當他們到達車站時,時間是3點鐘。”
5. Is this the factory ____ you visited the other day?
A. the one B. that C. where D. why
對于此題,有些學(xué)生選C. 理由是這個定語從句的先行詞表示地點。現(xiàn)在假設(shè)C是正確的,即Is this the factory where you visited the other day?而在定語從句中的謂語動詞visited為及物動詞,一定要帶賓語,但where是副詞,不可能充當賓語,所以假設(shè)不成立。由此分析,而得出正確答案應(yīng)為B.
6. _____ he really means is that he disagrees with us.
A. What B. That C. Why D. If
對于此題,考生不知選A還是選B. 其實答案為A. 現(xiàn)在假設(shè)B是正確的,即That he really means is that he disagrees with us. 這樣That he really means為一個主語從句,mean為及物動詞,缺少賓語,因為that只是起到連接作用,而不能充當賓語,所以假設(shè)不成立。
當解題感到困惑時,可以假設(shè)某選項為正確答案,將此答案填入句中,對全句結(jié)構(gòu)進行分析。這對解題可以起到良好的啟迪和導(dǎo)向作用。
