*****
I always wanted to travel to other countries, but I didn't have the opportunity to travel extensively since I married into the purple. I went to England six years ago, but I didn't go anywhere since then.

Hey, Elinor, you are the first winner!! How can you say, "Grammar is my weakness in learning English!" You have done a great job. I hope you are satisfied with Tim's pix as a reward. I didn't know that was Tim's original idea! Umm.......You are so lucky!!

I always have wanted to travel to other countries, but I havent had the opportunity to travel extensively since I have married into the purple. I went to England six years ago, but I didn't go anywhere since then.

-------------------------------------------------

Don't shy , just try it.

I got a question why "then" is used in the end of a sentense?

Rachel,

Let us give others a chance to win the gift from Tim.

Hey Kathy,

You did it better this time! Looks like you have understood how to use "tense" more! What you have done is almost perfect. Would you please think and try it again?
ps in this case, then = at that time



Elinor

Ok! I am sure there must over hundreds of members want to get the prize from Tim!! Let's see who the next lucky guy is! hehe.....

QQQ:

Thank you for telling me about"then". I have tried my best to think about the grammar question again. But I still don't know which part I need to revise.

Kathy,

Please refer to Teacher Big's explanation:

雖然Elinor所引據的B用法是存在的, 也可以接受, 但就較廣泛通俗的用法而言, since在作「自從」之意思時其從屬子句動詞仍是以過去簡單式為多, 尤其在考試時通常以過去簡單式為標準答案, 同學們請加以注意.

因此我認為這樣寫較為妥當:
There have been more than forty presidents of the United States since it became a country.

Rachel加註 : 由since所連接的主要子句通常用現在完成(進行)時式或過去完成(進行)時式

I have always wanted to travel to other countries, but I havent had the opportunity to travel extensively since I married into the purple. I went to England six years ago, but I havent gone anywhere since then

What a smart Kathy!! You got it!! Congratulation~~~~~

But why only you tried it this time? Huh?? Tim'x pix as a prize neh??
