The examples are good. Thank you. But I think there is a mistake in the explanation of the 1st example for ‘as long as’. It is written: (= If you don’t promise to give the book back next week, I will not lend you it.) It should be: (= If you don’t promise to give the book back next week, I will not lend it lớn you.)
