1. 你的表几点了？

What time is your watch? ✘

What time is it by your watch? ✔

这句话最容易错，可是问时间主语应该是it，而不是watch，所以要用說What time is it by your watch?

2. 你这一周怎么样？

How are you this week? ✘

How have you been this week? ✔

“This week”这一周，是持续的一段时间，要用现在完成式。

3. 当我上个月去日本的时候，我看见他...

When I went to Japan last month, I saw him… ✘

When I was in Japan last month, I saw him… ✔

这里强调的不是我去日本的这个事件或是动作，强调的是我在日本这个状态。

4. 你几点会到办公室？

When will you come to the office? ✘

When will you be in the office? ✔

用be更准确一点，因为用come会让人不清楚说的是出发的时间，还是到达的时间。

5. 我7天前就已经寄给你了呀！

But I had sent the parcel to you for 7 days. ✘

But I sent the package to you 7 days ago. ✔

中文中带有“已经”，可是英文中没有必要用完成时，应该是强调寄出去这个动作。

6. 我想我不会再遇见他。

I think I won't see him. ✘

I don't think I will see him. ✔

在英文中，I think/I feel/ I believe后面不加表示否定的句子，如果想表示否定，要在主句中表示否定。
