Mistakes Corrected

Things may be different as you thought.
--Should be, "Things may be different from what you thought" (or "from what you expected")

My brother has married and they have two children so far.
--"My brother" is the subject; you can't change the subject to "my brother and his wife," so to be correct, "they have" should be replaced with "he has". You can make it into two sentences, too: "My brother is married. So far, he and his wife have two children." (Notice we use "to be" for "married," not "to have".)

To my expect,...
--Should be, "According to my expectations..." or (and better), "As I would expect..."

--Note the difference between brave/bravery

personality of humor
--should be, "humorous personality"

Most of them are abuse.
--Should be, "Most of them are abused," or you could write, "Most of them have been abused." The latter is probably better.

--Note the difference between universal/universality

The article elicits three studies...
--This should be, "The article mentions" or "The article delineates...."


--Note the difference between stressful/stressed

It is Lisa who takes over the housework when Margie is hospitalized. However, Homer and Bart do nothing but lying on the couch watching television.
--"However" is not needed here because there's no conflict. Compare: "He studied hard. However, he still failed the test." <--In this example, there's conflict between expectation and result.

to be "American born Chinese" is inevitable to face the problem of racial discrimination
--The quote marks are fine because the author is quoting the idea of a Chinese person born in America; he isn't talking about the book title (which should be underlined). However, it should be, "if one is 'American born Chinese,' one inevitably has to face the problem of racial discrimination".
