--from the job ad.

Then your cover letter must directly address your capacity to perform such tasks.

yes,thank you for your help.

Ok, I know this is not a grammatical tip, but I think this can help you.
This is one of the tricks my business professor told us. Look at job descriptions to what the company is looking for. Pick up key words from it, and put it into your cover letter. Usually companies will receive a huge amount of applications and they will use a computer system to filter the "bad ones" out. They often look for key words. This way will give you a higher chance to get an interview! Good luck!

Very helpful,thanks.I didn't know this before, thanks for sharing with me!
