先解释reach的意思(只打上了这到达的相关意思):

reach:

[Tn] (a) go as far as (sb/sth/a place); get to or arrive at 到达(某人[某物])那里; 到达(某处): reach York by one o'clock 一点钟到约克 * reach the end of the chapter 读到这一章的末尾 * reach a speed of 500 mph 达到每小时500英里的速度 * Not a sound reached our ears. 我们一点声音都听不见. * The rescuers reached him just in time. 救援人员及时赶到他那里. (b) achieve (sth); attain 达成(某事物); 达到; 获得: reach a conclusion, decision, verdict, etc 做出结论、 决定、 判决等 * You'll know better when you reach my age. 你到了我这样的年纪就明白多了. * The appeal fund has reached its target of 10000. 吁请捐助的款项已达到10000英镑这一预定目标. * We can never reach perfection. 我们不可能做到尽善尽美.

现在进行解释:

用got时,一般是got to spc,所以没有相应的答案

用reach时,直接使用reach spc,所以答案选B.

注:这里没有时态的区别,如果是有不同的时态,还应对时态进行分析
