Question

I usually shopping and my sister on Sundays改为否定句？

Answer 1

题目正确表达应该是：
I usually go shopping with my sister on Sunday.
否定句：I don’t usually go shopping with my sister on Sunday.
解析：
1. 陈述句中没有be动词和情态动词时，需借助助动词do, 在实义动词前加don’t. do需对应原句时态和三单形式，动词则用原形。
这里是第一人称，时态分析是一般现在时，所以用do, don’t 即可。
2.如果陈述句中有频度副词，变否定句，否定词一般放于主语和频度副词之间。
即： don’t usually, 而不是usually don’t.
翻译：星期天我通常不和我姐（妹）一起逛街。

Answer 2

我认为shopping应该换成go shopping或者shop，原句差谓语动词。
and 换成with会更好一点。
Sunday的话不用加s。
变为否定的话就是
I don't go shopping with my sister on Sunday.

Answer 3

I usually shopping and my sister on Sundays改为否定句是

I don't usually shopping and my sister on Sundays.

Answer 4

这句话本身就错了，应该为I usually go shopping with my sister on Sundays.否定句为：I don't usually go shopping with my sister on Sundays.

Answer 5

I usually don't go shopping and my sister...
