你怎么样?

你们好，你怎么样？。[Chinese don't express this way. 你们好 = "you are good" is equivalent to "How are you?" 你怎啦 means "what's wrong with you?"! Very different in meaning] 我有二位哥哥和一妹妹。他们也住在 美国U.S。我和哥哥去吃飯 ["eat rice" means to have a meal]。我不太喜欢吃鱼[You need to have a verb here.  Translating from "I don't quite like fish" is wrong in Chinese.  It literally means you don't like the creature itself. ]，我喜欢吃咕嚕古老[What you just said that you like "ancient old meat" and not sweet and sour pork! LOL ]肉, 和抄炒饭和有蔬菜汤。周末的时的我喜欢在哥哥那边里休息。[What you wrote was literally, I like to rest INSIDE my elder brother!]

As you can see, translating literally from one language to another has plenty of pitfalls.  One figurative sense in one language does not have the same sense in the other :)

你怎么样?

你们好，最近过得都好吗？。我有两个哥哥和一个妹妹。他们也住在美国。我和哥哥去吃饭。因为我不太喜欢吃鱼，所以就吃了古老肉和炒饭，还有蔬菜汤。周末的时候我喜欢在哥哥家里休息。

1# “你怎么样?”could be replaced by "最近過得怎樣“ 

almost same meaning but more fluency than 你怎么样

2# If something is countable, you need the " unit "

3# you could say 吃飯 吃東西, it is better than saying 吃

    and if you "had" eat something you could put "了" after “吃” 

     I ate the president lest night = 我昨天晚上吃了總統．

4# 周末我喜欢在哥哥里休息。 means : I like to stay in my "brother" at the weekend.

     週末我喜歡在哥哥家裡休息． means : I like to stay in my "brother's home" at the weekend.

     家 = home

Your Chinese is way better than my english, its my pleasure to help any foreign people to study chinese.
