Please help me correct! I would appreciate it if you leave your thought on this topic in your comment:) Topic: Will humans live on other planets someday? I believe that humans will live on other planets someday, and I have two reasons to support this opinion. Firstly, the earth has been being destroyed recently. We have witnessed a lot of unusual natural disasters such as fierce wild fire and big hurricanes caused by global warming. These are bad signs that the earth is on the verge of collapsing. We need a different place to reside and survive in. Secondly, space technologies have been developed dramatically nowadays. Traveling to space was not for a regular citizen before. However, it has become more popular among rich people. In the future, more demands to go to space will increase so the demands will inspire the space industry to develop technologies eventually. For these reasons, I believe that humans will live on other planets someday in the future.

This looks correct. The context would determine if the use of "the" is correct and whether "voice" or "ask" sounds better.

We are preparing special foods We prepare special foods.

Sounds good to me!

Prepositions are so tricky...someone else here pointed out that working "with" computers is slightly different, and working "on" computers is also different (means you are fixing computers).

Yes, this makes sense and sounds better without "the".
