D．while

Answer 1

B

試題分析：考查時間狀語從句：做好此題的關鍵是正確理解上下文的語境。在此句中，it是代詞，指代 the bike，句意為：“當你離開去同朋友談話的時候，你的自行車是在這樹下嗎?”“當然，但當我回來時，自行車就不見了�！奔偃� A，為強調句，句子即為 Was it under the tree that you were away talking to a friend? 把強調部分去掉：句子則為 Under the tree while you were talking to a friend，不成立一個句子。選 B。
點評：此題很容易誤選 A，認為這是強調句型。關鍵是要會判斷，平時練習時要有這個意識。it is /was+被強調部分+that/who+…判斷方法是去掉it is /was  that/who句子不缺成分，即為強調句型。這句話卻不是。
