Question

9. This kind of training seems anything but helpless;it proves,in fact,very         .

   A. worthwhile   B. distinct

   C. straightforward   D. valid

Answer 1

9. A解答此题的关键是理解题干的短语anything but ,"根本不，决不"，加上其后的一个否定形容词helpless ,就构成了双重否定，即为"肯定"。因此，选A项。 worthwhile"有价值的"；distinct"清晰的";straight forward"简单的，直接的"；valid"合法的"。
