[題目] 600題P.152,Error Recognition第7題

[ssiou (像你一樣堅強)]

7. For more than a decade the young woman had systematically experimented
   with ways to generate more power from trash, to solve two problems at once.

   正解是(D):solving  我知道前面3個選項是對的,但為何不能用to solve???
                      而且整句的結構我看不太懂,逗點後面這句的主詞動詞我找不到

→ scju        :應該是這樣啦 有錯還請指證@@"
→ scju        :而且不是已經不考挑錯了嗎= =
→ icelaw      :不能用to solve 因為這樣子就會變成兩個動詞
→ icelaw      :只有Vpp/Ving 才能形成分詞構句
→ ssiou       :感恩各位高手,可能要拿文法書出來看一下了!!!
