If you want to write three parallel imperative sentences, you have to solve two problems.

One is to understand what an imperative sentence is. Imperative sentence is to ask the other party to do or not to do something, with imperative mood. Imperative sentences are divided into four categories. (1) said the imperative sentence of the command. Such as "you stand up!" (2) Imperative sentences expressing requests. For example, "Please sit down." (3) Imperative sentences indicating prohibition. Such as: "Don't talk nonsense!" (4) Imperative sentences expressing dissuasion. Such as "not a few words!" .

The second is to understand what is the juxtaposition of sentences. The coordinate relationship means that all clauses are equal and coordinate, regardless of primary or secondary. Say several related situations or aspects of a thing in each clause. She sang as she walked.

Make these two questions clear, and you can write the answer better.
