Question

Though the horses got off to a good start,it was not long ___ over half of them were out of the race.
a.after b.until c.when d.before

Answer 1

选:d.before
It is/was +时间段+before从句:表示在做某事之前有...时间; 过...时间就...
It is/was not long before ...过不了多久就.
get off to a good start 有一个好的开始 /开头顺利
out of the race退出比赛
句意:虽然那些马开头顺利,但过不了多久,其中超过半数的马就会被淘汰出局.
