-You speak very good chinese.
-Thanks.I _____it for 4 years before i came to China.
-You speak very good English.Have you ever been abroad to learn English
-Thanks.I have never been abroad before but I ____ English in Beijing Foreign Language University for four years.
第一个填had studied 第二个填 studied
为什么有不同?
你的问题很有质量,是我今年碰到的最有质量的问题.我很乐意解答.
1 第一个填had studied ,是因为句子里面有 before i came to China.说明had studied的这个动作发生在came以前.---------came是过去的事情,而had studied是过去的过去.
2 第二个填 studied ,是因为studied这个动作发生在“过去”.与“今天”无关.
请比较这两句:
I have stdied art for two years---------强调:art我现在还在study,所以是现在完成时
I studied art for two years-------- 强调:art我现在已经不study了,所以是一般过去时.
现在,你明白了吗?
