Question

Some groups still have difficulties ________ access ________ social services.

A ． gain; in  B ． gaining; to

C ． to gain; to  D ． gaining; of

Answer 1

B 　考查非谓语动词和介词搭配。句意：一些群体仍然很难得到享受社会服务的权利。 have difficulty/trouble(in)doing sth.“ 做某事有困难 ” 和 access to sth.“( 使用或见到 …… 的 ) 机会 / 权利 ” 都是固定用法。
