問題詳情：

The boy is only five years old, but he can play golf well.

A. able                                             B. is able

C. be able to                                    D. is able to

【回答】

D。考查固定短語。be able to意為“能夠; 會”, 與can意義相近, can無人稱和數的變化; 而be able to有人稱、數和時態的變化。主語是he, 時態為一般現在時, 因此句中要用is able to。故選D。
