Do So / Do It / Do That Exercises
B2 Level
English Exercises is teacher-led by Charlie. About the teacher · How content is made
The form changes with tense and structure: do so, does so, did so, done so, and doing so. Formal phrases such as "failure to do so" and "those wishing to do so" are common in notices and policies. In conversation, do it often feels more natural than do so. Choose the substitute that matches both the repeated action and the register of the sentence.
Quick Rule
subject + do/does/did/done/doing + so/it/that to replace a previous action; use so for formal register, it for informal tasks, and that for a specific action or behaviour
- 1.Applicants may submit the form online, and many do so before the deadline.
- 2.I need to clean the kitchen, but I will not do it until tonight.
- 3.She changed the password without telling us, and nobody knows why she did that.
- 4.The board promised to review the policy, but it has not done so yet.
