A. 通常星期天你们做什么这个星期天我们去购物好吗用英语怎么说

B. 我今晚要去购物。用英文怎么说
I will go shopping tonight
C. 咱们今天下午去购物吧用英语怎么说

D. 我妈妈上周去购物用英语怎么说一句话
My mother went shopping last week
E. 去购物用英文翻译
go shopping
F. 我打算去购物。 英文翻译应该是I am going to shopping.还是 I am going shopping.
如果用你句子，那么应该用第二个。虽然两个词都是分词形式，但是第一个构内成一个时态，第二个容又与动词构成一个词组。
当然其他的说法也有。比如：
I‘m planning to go shoping.
I'll go shopping.
希望对你有帮助。
G. 今天谁想去购物 用英语怎么写
Who want to go shopping today?
H. "我想要你今天和我一起去购物"的英文翻译
I would like/want you to go shopping with me today.
