It would be nice to see you try this exercise first, EnglishGirl. Post your effort here and we'll check it for you. (Hint: perhaps you mean two sentences which will be put into one sentence containing a relative clause?)
Yes, I meant that. I do not have any examples that I do not understand from my books, but tomorrow I am taking test and the teacher will give hard examples. So I would like if anyone could give me a few examples or a link. I am looking for advanced and complex sentences.
*** helps those who help themselves. We would like to see you make an effort at constructing the kind of sentence you require. Then we will check your effort.
The point is that I understand all the examples I have in my books. I do not have anything to ask about them. I would like to get advanced practice but I can't find it anywhere. That's that...
