Question

when i was a child, i never used to eat meat,but i eeat it now. used to eat 可不可以用ate

Answer 1

When I was a child, I never used to eat meat,but I eat it now. used to eat 可不可以用ate
答：used to eat 可以用ate。但是，used to eat 强调【过去做，而“现在”不做】。如上述题就是【相对but I eat it now的“过去从不”】

Answer 2

既然前面都说when i was a kid，就不必在用used to do 这个句型了，显得多余。你可以说when i was a child, i never ate meat
