本人正在初学英语， 请问下面的英语句子更改后正确吗?请问那句错误呢？谢谢

1.where do you live
2.我认为前后的都对，只是时态不同，含义不一样，你还可以说：He works very hard或者He has been working very had.
3.对的或者 I have never been late for this class.
4.I'm never late for this class.
5.Do the class start on time? 或者 Did the class start on time? 同样是时态不同，含义不同
6.正确

1. where did you live? live这里为动词， 居住
2. 改对了
3. 改对了
4. 改的没有语法错误，若想符合原句意思，可说i have never been late for this class 这里class可以理解为一门课而不是单独一节课
5. did the class start on time? start这里是动词，不可以用are提问
6. 改对了

个人意见。希望有帮助

1. Where do you live?
2. 正确
3. 可以, 但最好用过去时：I was not late for this class.
4. I am never late for this class.
5. Did the class start on time?
6. 正确

1. Where do you live.
2. He has worked very hard.
3. 对。
4. I am never late for this class.
5. Did the class start on time?
6. 对。

1，应改为Where do you live?
2，应改为He worked very hard.
3，应改为I'm not late for this class.
4，应改为I am never late for this class.
5，应改为Did the class start on time?
6，应改为 Did he study English?
共同学习，希望能帮到你。
