1. I watch documentaries when I feel down.

Question

(What is the meaning of 'feel down'?)

2. This is a news program.
This is an animation program.
This is a game show program.
This is a soap opera.
This is a comedy program.
(Are the expressions all correct? They are TV programs.)

Answer 1

1. The expression is correct. The phrasing "feel down" means having a feeling of depression or sadness or pessimism.

2. All are correct, and yes, all are types of TV programs. The more common way to say the second one is to replace "an animation program" with "a cartoon."
