Help me do 5 high school English questions

1.pace Small coal mines are closing at a rate of three a year.

Speed ??and rate refer to specific speed. If they only refer to speed, they are interchangeable. For example, at a speed/rate of 80 yards. step refers to steps. Pace refers to the speed of business development. In this question, only three coal mines are closed a year, which must be a long process, so pace is used here.

2.message Nowadays, many people greet each other through text messages.

SMS. Fixed matching, just remember it.

3.scene As soon as I see the students busy preparing for their homework, I can't help but hope that they will be admitted to the university.

Scenery generally refers to the stage scene. sight scenery also refers to eyesight. View refers to point of view, field of view, scenery. Scene refers to a scene in a drama, but also refers to a shot or scene in life, so it is suitable to be used here.
