改正错误英语l'm do my homework

l'm doing my homework.(be后面动词用现在进行时态)固定用法
They need to work hard.(to后面动词一律用原型）固定用法
What colour do you like?有动词like了，不能再用系动词，又是特殊疑问句，所以用do。
The cat is beside the ball.（between，两个物体者之间，猫不能在墙之间，只能在旁边
Can I have some cakes? 第一人称用动词原形，第三人单数才用has

l'm doing my homework.(be+现在进行时
They need to work hard.(to+动词原型
What colour do you like?
The cat is beside the ball.（between，两者之间0
Can L have some cakes?

I'm doing my homework. ( 正在进行时态加 ing ）
They need to work hard. ( need to do sth )
What color do you like? ( 动词前加 do ）
The cat is between the two balls. （ between是在两者之间，又是复数，故为 two balls ）
Can L have any cakes? （ 问句用any+复数形式 )

I'm doing my homework.
现在进行时结构：be + doing

they need to work hard.
需要做某事 need to do （4楼说的不对，to 做介词时后面就加动名词doing，如期望做某事 look forward to doing sth.）

what colour do you like？
like为实义动词又名行为动词，提问用助动词do

the cat is beside the bal
