Proofreading

I took on the job of proofreading.

I got myself a job proofreading.

Tom did a good job proofreading my paper.

Tom did a good job proofreading Mary's rough draft.

Tom spent all night proofreading his thesis.

I'm proofreading my essay.

I do my best proofreading after I hit 'send'.

You should've spent more time proofreading your report.

"These letters still need proofreading." "Tom can do that." "The boss only trusts you with these things, Mary. You know that."

Do you really want to trust Tom with proofreading your essay?
