Donot sit on the desk错了吗,错在哪

Donot sit on the desk错了吗,错在哪 翻译sit on the floor 请问sit on the committee 是sit in the sofa 还是sit on the sofa? 是sit on the chair还是sit in the chair Sit on the grass.还是 Sit in the grass? on the Avenue des Champs Elysees还是in the Avenue des Champs Elysees sit on the grass sitting on the grassland 哪一个对?sit on the grassland Sit down on the chair.是什么意思 Sit on the desk变为否定句 Jane is sit quietiy on the sit on the bed什么意思? I sit on the football是什么意思! Why donot you go to the park on foot?同义句 sit it on sit on it sit on the chair sit the chair on 以上哪种说法是错误的,快 Pam is on the ship.She sit on the chair. 做在椅子上是 还sit on the chair 还是sit on the chair Let’s （）（sit）on the bench.Don’t （）（sit）on the grass.
