4. There may be, somewhere outside the solar system, intelligent life____ messages to us.

A. sends B. sent C. sending D. has sent

【答案】C 兩個(gè)逗號(hào)中間為插入語(yǔ)，在分析句子結(jié)構(gòu)時(shí)，可以省略;略去后得There may be intelligent life ___messages to us.因此后面的部分應(yīng)該是intelligent life 的定語(yǔ)，選sending，相當(dāng)于(that is )sending…; 全句意為“在太陽(yáng)西外的某處，可能有某種正在項(xiàng)我們發(fā)送信息的有智慧的生命�！�
