Can you tell me what is the function of the world "ce" in this sentence ? " on va demander aux gens CE qu'ils aiment manger ? " As I know, "ce" means this or that, so does it mean this or that in this case ?

What are the differences between "既。。。也“ and ”又。。。又“ and ”一边。。。一边" ?

Can you explain for me how to use this word: “着” ?

How to use "would" and "used to" correctly ? This is my example: "When I was young, I used to go to the beach" So, in this example, rather than "used to", can I use "would" ? and why ?

How can I use past perfect and past perfect continuous properly ? I have an example like this one "When I looked out of the window, It had been raining" So, in this example, instead of using "had been raining", can I use "had rained" ? Because I'd say that they have the same meaning that when I looked out of the window, it was no longer raining anymore.

Could you show me which is the difference between "adapt" and "adjust" ?

A conversation with my friend I have a friend whose name is Viet. He is a tall, kind of a handsome guy and a good friend too. I was talking to him this afternoon and our conversation was mainly about his job. He was very open-hearted when he told me about his job as well as what he actually acknowledged about finding a job. It’s typical of me to think that we all should spent our time on learning in order to gain more knowledge rather than looking for a job, because I’m just a sophomore, I assume that’s a right thing to do. But with everything that he informed me about how hard to get a job and how important hands-on experience could be, he totally changed my way of thinking. I’m not afraid of applying for a job anymore and I know what I should make the best of every opportunities that I have. “Now it’s time to leave your capsule if you dare” And I think I do, now.
