A．when

B．after

C．since

D．where

Answer 1

D

試題分析：句意：很有趣的是在一段時間之后許多減肥的人又胖了回來，又回到了原點。首先，整個大句子是一個主語從句。it充當形式主語，句子還原后應為：Many people who lose weight gain it back after some time and end up back where they strated is very funny.
其次，句子的主干部分為Many people is funny. 其中用了一個who引導的定語從句修飾先行詞many people表示 是怎么樣的"許多人"。然后，end up back where they started 實際上是  end up (coming) back where they strated 是一個地點狀語從句。這邊的where是一個抽象意義的地方。故選D.
點評：狀語從句也是高考的�？键c，它可以修飾謂語、非謂語動詞、定語、狀語或整個句子。根據(jù)其作用可分為時間、地點、原因、條件、目的、結果、讓步、方式和比較等從句。狀語從句一般由連詞(從屬連詞)引導，也可以由詞組引起。
