看了解释，还是不太明白BC二个选项。哪位能再指点一下呢？B项说的是，between and破坏逻辑结构，这不太懂。后面的should begin to be successful, 可直接改成should begin successful?C项说，should be begun错，这是范了什么错误呢？还有，我选的错误答案就是C.本人语法很菜，还请大侠提携！

between and 很少有表示时间的范围的 确实很别扭 within 很好 表示的在某个时间范围以内

shouls begin to be successful 我觉得语法没什么问题只是表达的意思不一样

想想 begin within 4 mins to be successful 和begin to be successful侧重点是不一样的  前者强调再一定时间短里开始才成功，后者说开始就成功，不够准确。

should begin successful 肯定不对啊...至少也是successfully, 而且这么表达还赶不上to be successful 因为successfully 直接修饰begin了 更不强调时间范围了，要注意句子的中心

我也想问 should be done有问题？  I should be killed. U should be awarded   这不很常用么

begin 是可以主动表被动的，印象中没见过 sth be begun 的表达，以下是节选自 LDOCE 的解释
2. start happening[intransitive and transitive]  if something begins, or you begin something, it starts to happen or exist from a particular time:
It was the coldest winter since records began.
