1. We shall appreciate ____ from you soon.

　　A. being heard B. hearing C. to hear D. having been heard

　　【答案】B.appreciate+doing：“感謝，欣賞”。此處hear from sb：從……收到來信，應(yīng)該用主動(dòng)語(yǔ)態(tài)，后面的sb.是hear from的賓語(yǔ)，故A，C和D項(xiàng)不對(duì)。

　　A. losing B. to lose C. lost D. your life to lose

　　【答案】A.risk后面接doing形式，意為：冒險(xiǎn)做某事。

　　3. The scientist didn't mind_____ and went on with his investigation.

　　A. laughing at B. to be laughed at

　　C. being laughed at D. laughed at

　　【答案】C mind doing sth.“介意”是固定搭配;而此處科學(xué)家是被嘲笑的對(duì)象，是“介意被嘲笑”，所以選被動(dòng)式C項(xiàng)being laughed at。

　　4. John suggested ____ anything about it until they found out more facts.
