reaching.现在分词作结果状语.A是谓语、C、D都是不定式的形式.这里等同于一个非限制性定语从句、可作which reaches.此句也可换成:Oil prices have risen by 32 percent since the start of the year and reached a record US$ 57 a barrel on April 4.
不定式表结果,其动作发生在谓语动词之后,往往表示未曾预料到的或令人不快的,不定式前常加only;另外,还用于too…to,enough to,never to,so/such…as to等固定结构中.现在分词表示的结果,是伴随谓语动词的发生而产生的自然结果(同时发生),有时在前面加上thus,谓语动词与现在分词的动作是因果关系.因此、该题B是最佳选项.

选B
句意是
石油价格从年初以来已经上涨了32个百分点,在4月4日达到57美元每桶的记录

B。
前面的句子已有谓语动词have risen.后面只能用连接词
或分词连接。选项中没有连词,只能能选分词。油价上涨到一桶57元是主动的,
无被动。所以选V+ing.
