Я пишу исключительно на английском профессионально 20 лет и имею некоторое представление о разнице между языками. Спасибо. Дайте, пожалуйста, ссылку на ваш источник информации, чтобы я, если вдруг что-то упустил, мог бы восполнить свой пробел.
Imperative sentences are independent clauses, so when one is joined to another independent clause with a coordinating conjunction, a comma is required before the conjunction.
When one or both verbs are in the imperative and the subject is not expressed, treate the sentence as a compound sentence and use a comma between the clauses. For example, • "Please look at the brochure I have enclosed, and then get back to me if you have additional questions." • "Call Ellen Chen sometime next week, and ask her whether she will speak at our conference next fall."
