Hi I am a Chinese student studying in U.S. now.

男女平等是现代社会的成果，几十年前，即使是在最发达的国家,女人的作用也只局限在家里。今天许多国家的法律宣布男女平等，然而很多情况下，女人继续被男人压迫。
翻译: 男人和女人的平等是一个现代(世界)的收获: 到几个年代前, 也在发展的国家, 妇女的作用限于家里. 今天很多国家的法律宣布男女平等, 然而在很多场合女人继续被男人压迫. 他们（who?)不会了解女人和男人身体的区别代表男人和女人智力水平和社会地位的不同。性别的不同给私人生活带来了意义，但不能决定男人和女人的社会地位。

This is what I gathered from the context.  So if I'm wrong, please let me know.

翻译: 男人和女人的平等是一个现代(世界)的收获: What you are saying is sex equality is the reward (what you reap) of today's world. 男女平等是現/世/代/ 的爭取. 剛剛到几十个年代前[What you said here is a few years ago, not decades as you said in English], 甚至最有也在发展的国家, 妇女们仍然的作用限于家庭細务[literally family small chores, i.e. domestic work]里. 虽然今天有很多国家的法律申明宣布[too weak, it just means announce without teeth.]男女平等, 不过, 还是然有而在很多场合女性们还人继续被男人压 視迫 [Unless you are talking about extreme middle eastern countries, 压迫 may be too strong.  Just my opinion since I don't know the original article]. 男女的确有身外性理之别, 但是这些人还他们不会了解女人和男人身体的区别並非会影响各人的智慧[The Chinese language is very sexist. Males must come before female.  It's just like in English, you cannot use "I and she" but the other way round.  (However, there are some exceptions, 陰陽 and 雌雄, remnants of a matriarchial Chinese society before Confucianism took over) You can't fight tradition.  As you delve into the language, even the characters are extremely sexist.  For example, 如 = if because a woman's words are iffy!] , 不表示一个智力或社会的区别. 男女 之的区别给我们的有私生活的趣意思, 但在公 众大场上, 履行职责 应毫无有別 关, 女人或者男人是不要重视的. 我们可能还要等久时间, 直到妇女可以获得一个显达的地位....and then I had no clue how to go on...lol  只怕我们还要等着很久的时间, 才能有一天, 女士们在那些仍存有重男輕女的国家, 能登上其国至高的职位.

Yes, I admit this is difficult but not impossible.  Except for some expressiveness and choice of words, your written Chinese is good.
