I recently went to a tennis tournament that was held in the school opposite to oursa neighboring school.

Our form teacher took our class there during our form time so we could cheer up for our friend Tom who. Tom was one of the competitors, and who was supposed to be the best tennis player in our school.

This is a run-on sentence. Native speakers struggle with run-on sentences too. However, I have found it useful to try and limit your sentences to one or two ideas. For instance, you are introducing three ideas here: your form teacher taking the class to cheer for Tom, Tom being a competitor in the tournament, and Tom being the best tennis player. I fixed this sentence by introducing the first idea in one sentence, and the other two ideas in a different sentence. It is easier to follow what you are saying if you avoid run-on sentences.

After the opponent’s tossed a coin, Tom got to serve first.

When he took a big bite of a banana, he seemed to have recovered from fatigue.

To me, the organisers of the event are worthy of praise for shadowing the court, and not exposing us to sunburn or heat exhaustion.

Using the word shadowing in this context is not common, but correct. I would prefer the word shading. Shadowing is usually used when describing someone who follows around a worker at their work place (e.g. someone who shadows a doctor, would spend a work day with the doctor to learn what a typical day looks like for them).

Personally, I recommend watching sports competitions live - i. It's a good revision ofway of learning the game rules, and a good way to bond a group of fans into a closely knit teamwith a fan group.

Revision is typically only used in an academic context (e.g. revising for an exam).
