单选题 ______, he swore that he was not asleep.
  • [A] Although I had difficulty in waking him
  • [B] Since I had difficulty in waking him
  • [C] Being difficulty in waking him
  • [D] Even if I had difficulty in waking him


【正确答案】 A
【答案解析】[题意]尽管我叫醒他有困难,但他仍保证说他睡得不熟。
[解析] 四个选项中的difficulty in waking him与题干中he was not asleep存在着意思上的转折关系,故所填的从句应当表示转折关系,答案为[A]。
