问题解答:

我来补答
She went to the beach three days ago.
在句子末尾时,before多用于完成时态,ago多用于一般过去时(注意,如果是since.ago的,还是用完成时态)
再问: 举个例句可以吗?谢谢!
再答: Have we met somewhere before?
我们以前见过面吗?
I started to learn English ten years ago.
10年前我开始学习英语。
I have known her since two years ago.
自两年前我就已经认识她了。
再问: 感谢,不过刚才有个人说
再问: ago是现在完成
再答: 现在完成时的标志性词语有:
for+时间段,since+过去的某个时间,ever,never,already,yet等等。
一般过去时的标志性词语有:
last...,...ago,after...等等
