Question

紧急！一道很简单的英语时态题。

Moder medicine________(begin) in 19th century.

空格里是什么？...最好解释一下~
--------------
有些人说用 has began....这个对吗？

Answer 1

都不对啊 ~~应该说begin 是个瞬时性动词~~没有持续性，也就没办法有现在完成时和过去完成时~~只能是一般过去时~~，就是Moder medicine began in 19th century.

Answer 2

Modern medicine began in 19th century.
现代医学始于十九世纪。因为开始的时候早已过去，是过去时，所以用began.

Answer 3

in 19th century很明显是一个过去的时态,所以这个句子应该用过去时

用began

Answer 4

were began 听一个不大明白的小姑娘这么说的,先用着吧....

Answer 5

was begun
