Question

i clean the room and washed the clothes改为否定句？

Answer 1

原句时态不一致，应改为I cleaned the room and washed the clothes. 或者 I clean the room and wash the clothes. 变为否定句时过去时加didn’t, 现在时加don’t, 谓语动词还原成原形，and 换成or 。即：I didn’t clean the room or wash the clothes.

I don’t clean the room or wash the clothes.

Answer 2

这句话有两个不同时态clean和washed在这个情况下不可以放在一个句子里，如果是cleaned的话否定句就是，I did not clean the room nor wash the clothes.

Answer 3

I cleaned the room and washed the clothes.
改为否定句
I didn’t clean the room or wash the clothes.

Answer 4

i clean the room and washed the clothes改为否定句是i didn’t clean the room and wash the clothes

Answer 5
