have / has + 过去分词

Have you ever …? / never：有没有……过

问一个人有没有做过某事，就说 Have you ever + 过去分词？回答没有，就说 No, I haven't 或 I've never + 过去分词。

• Have you ever played tennis?

• No, I haven't.
• 试一试: Man: Do you know the Neshom Note? Woman: No. I've ___ been there. 选出那位女士会说的话。 (always / never / ever) 答案: never — 她不知道那个地方，所以她从没去过：never。

been 还是 gone？

人去了又回来了，用 has been to 某地；人还在那里，用 has gone to。

• I've been to Ghafwick. It's a nice place.
• They've gone to Senville Park for the day.
• Not "Mom has been to Farris Supermarket. She isn't home." — say "Mom has gone to Farris Supermarket. She isn't home.". 她还在那儿，所以用 gone。
• 试一试: Man: I need to talk to the teacher. Woman: She's ___ to the office. She's coming back soon. 选出那位女士会说的话。 (been / gone / was) 答案: gone — 她现在在办公室，所以是 gone there。

不和已经结束的时间一起用

have / has 不能和已经结束的时间一起用，比如 yesterday、last week 或 in 2019。要用过去式：I went there last week。

• She called me yesterday.
• They left at six this morning.
• Not "I have seen him yesterday." — say "I saw him yesterday.". 有 yesterday 的时候，用过去式。
• 试一试: Woman: Is your homework done? Man: Yes. I ___ it last night. 选出那个男人会说的话。 (have finished / finished / lost) 答案: finished — Last night 是已经结束的时间，所以他说 I finished it。
