C、 The U.S. economic growth is expected to continue.

【正确答案】 B

【答案解析】解析：题目问新闻主旨。新闻开篇便说“美国央行将一项重要利率提高了0．25个百分点”。之后解释了加息原因。B“美国央行提高了利率”将首句加以提炼，去掉具体的数据，表明了全文主旨。

A、 It is expected to grow.
B、 It is set below 1 percent.
C、 It would affect interest rates.
D、 It would be good for price stability.

【正确答案】 D

【答案解析】解析：题目询问由美国央行设定的target infla-tion rate“目标通胀率”的相关信息。新闻提到央行将target inflation rate设定在2％，央行表示该通胀率有助于支持就业(help support employment)和保持物价稳定(keep prices stable)，D中的price stability与后者对应，其中的stability是stable的名词形式。
