補(bǔ)全短文

Pain is the most common reason we go to a doctor. It is the most common reason we take medicines. Until recently, however, most doctors knew of only a few drugs that stopped some pains. ________. But new knowledge about the process of pain is helping them to control pain better.

A、Yet we need pain.

B、They knew little about the process of pain itself.

C、And others have painful attacks all the time.

D、It is our body's Warning system.

【正確答案】 B

【答案解析】 空句所在的段落主要講的是治療疼痛的發(fā)展，許多醫(yī)生只知道少量可以治療一些疼痛的藥物，這是由于缺乏對(duì)疼痛過程的認(rèn)識(shí)。此處前后process也是對(duì)應(yīng)詞。
