忘记带雨伞用英语

" 下雨了,他忘记了带雨伞和忘记关窗户." " It was raining and he had forgotten to bring his umbrella with him and close the window." 用过去完成时 had+ forgotten +to do sth...因为忘记带伞和关窗的动作发生在下雨（过去时）之前。forget doing sth 忘记做过某事。忘记是否带伞和关窗。这个用法不符合原意。 【公益慈善翻译团】真诚为你解答！

Forgot to bring an umbrella.I forgot to bring an umbrella.

Don′t forget to bring your umbrella.这是祈使句

It's raining now,but he forgets to take an umbrella and forgets to close the windowsforget to do,忘记要做某事forget doing,忘记做过某事，显然应该是forget to do

Don't forget to bring your umbrella.
