Whether the university should accept equal numbers of male and female students in every subject is a commonly discussed topic and is still in debate. Some people claim that it should be the policy; otherwise it will raise a discrimination based on gender. But from the point of my view, the ratio of man and woman students in college ought to be different depending on different areas. First of all, let us talk about the so-called first nature. In general, boys love machines much more than girls do from their early childhood. Boys like playing with cars and games, while girls love Babe Dolls and decorating their bedrooms. It can certainly be expected that more boys are interested in engineering, and more girls intend to choose literature or education when they grow up. Secondly, psychologically speaking, men are more logical and women are more sensitive and careful. That is why you see dominant party of girls in nursing school. At the same time, dealing with mathematics is a piece of cake to boys but a big disaster to most of girls. To choose a subject depends on the individual’s personality, so it will be unreasonable for the university to take equal numbers of males and females in every subject. At last, in today’s society, there are still different social responsibilities to males and females. Even though in more and more fields, for example, biological research or computer science, you can see no big difference between the two genders and boys or girls are doing equally well, there are certain areas preferring one gender but the other one. We are all used to meeting a sweet nurse in white at hospital but may feel weird to see a big guy injecting flu shot to you. From discussed above, we can easily see the truth that males and females have physiological differences and are interested in different fields. So I can not see a convincing reason to urge the university to accept equal numbers on male and female.
