Tom didn't watch TV ____ half past nine p.m A after B until 我知道选B但谁能详细的告诉我为什么A不能选?not until 我也知道.但老师问我们为什么after不能选 TOM在9点半以后不看电视 意思不行么,o(︶︿︶)o 唉

改错：1 Tom wasn't watch TV last night 2 I didn't my homework yesterday Tom wasn't watch tv last night这句话错在哪!是将wasn't改成didn't wasn't 和didn't怎么用例如：Tom wasn't watch TV last night .为什么要把wasn't改为didn't呢? Tom didn't watch tv that evening.He listened to music.(保持句意不变)Tom listened to music ( ) watching tv that evening Because I didn't watch TV这句子可以吗? “Tom wasn't watch TV last night.”是否有错? Tom wasn't watch TV last night.错在哪儿? Tom doesn't watch TV in the evening(肯定句) Tom didn't watch TV ____ half past nine p.m A after B until 到底应该选哪个?after 为什么不行? We didn't watch TV.We played football instead.We played football _____ _____ _____ TV. When we didn't watch TV,we turns off the TV.句子有错误吗 Don't watch TV. Mother didn't watch TV last night. She was ill（改为同义句）Mother didn't watch TV last night_____ _______ illness.请说明一下理由 一般过去时练习题4．I can fly kites seven years ago. ______________________________ 5Did you saw him just now. ____________________________________ Tom wasn’t watch Tv last night.________________________________ 7 I didn’t my homework yes Linda didn't watch TV last night.Her sister didn't.either________of the two sisters_______TV last night. Linda didn't watch TV last night.She was ill.合为一句 He didn't watch TV last night.是错的,还是对的 He didn't watch TV yesterday改成一般疑问句怎么改?
