Question

The thing I can't understand is the inversion subject verb in the sentence with "as"
1) The Asiatic lions are in danger of extinction, as are the Asiatic cheetahs. (like the Asiatic cheetahs/ as the Asiatic cheetahs are)
2) They have accepted my proposal of a partnership with your school. The idea of letting our students work on a common theme concerning the EU seems particularly interesting.
3) A similar project called "Citizens without frontiers" will be sponsored by the savings bank of our Province. So I believe we can get some financial backing by them, too

Answer 1

In 1, the subject and verb don't have to be reversed. You can also write this: <i>Asiatic lions are in danger of extinction, as Asiatic cheetahs are.</i>
(I would not use "like" in any construction of the ideas in that sentence; it's too slangy, in my opinion!)

2. OK

3. A similar project called "Citizens without Frontiers" will be sponsored by the savings bank of our province. I believe we can get some financial backing by them, too.
