Hi Edward, thank you for doing your homework. ^-^

The sport that i like most is soccer.
Correct: The sport that I like the most is soccer.
>> We use " The most " with a noun to mean more/less than all of the others.

I like soccer because i`m not very good at soccer,
but i just like soccer.[I have no reason.]
>> " I " should always be capitalized.

[Is the homework has to be more then three stripes?]
