They __ shares in a new stock market.A Bought B have bought C was buying 应该选哪个?
不好意思，C选项是were buying
不好意思，C选项是were buying
C肯定不行的,they was buying这个是语法上的错误,they were buying 才对的.
B跟A的话,have bought shares 语境上是不对的,他们已经买了股份,一般会有already,或者时间段的,但是没有.
所以答案是A.过去时,They _bought_ shares in a new stock market.
按照楼主修改的话,我们假设给个语境,what were they doing?they were buying shares...这句话是行得通的.
they bought shares是过去时,他们在新的股票市场买了股份,这句话也行的通,A/C感觉都行得通啊.
但是个人感觉偏向C.
