英文文法是否正確

No. 1. what do you like doing? is not correct. You can say: what do you like? (你喜歡什麼?) But the question is too broad. A better question should be more specific, you can say: what kind of food do you like?

No. 2. what do you like to do? (你喜歡做什麼?) is correct.

Both are correct.

2個都正確

第二個對。
不過你第一句可以變成what are you like doing?都可以解做你喜歡做什麼?
意思同第二句都一樣。
^^希望可以幫到你啦

2個都正確

Both are correct.

"like" is a GERUND as well as a TO-INFINITIVE.

No.2 is right
