我以为今年最后一个星期的工作不忙，可是我错了！

因为同事都已经回来家了，我以为这个星期我的工作就会比较闲没有很多工作。可是恰恰相反我做的工作反而做得很多更忙！我的天啊！所以本来上个周末我是休息的，因为太忙，所以我没上网在iTalki。但是这个星期我终于有时间了！

(I have a feeling the word order in my title in wrong, I've been trying to learn to get it right. I am trying to say "I thought the last week of work this year would not be busy, but I was wrong!")

Merry Christmas!

Hello!

I didn't understand the connection between the certain contexts. (A good chinese writing not only contain no mistakes in one sentence,but the clarity in the contexts is also very important.)

I don't know if my correction express what you really want to say.

(因为)同事已经回来(了)家，(所以)我以为我没有很多工作，可事实上，我要做很多做工作！我的天啊！所以(因为)上个周末我休息的，(所以)我没上iTalki，但是这个星期我有时间！ 

We may use many different ways to express the same meaning,but we should choose the way which is the most fluent to say.

Well Done!
