Please correct my words, thank you for your kindness! In recent years, there is always a controversial issue that between having broad knowledge of many academic subjects and specializing in one specific subject,which one should be chosen. From my perspective, it can not to say which one is better, I suggest to discuss it for the situations. For secondary-level or primary-level students, they are still in their formative years, they have no definitely cognition about what they will do in the future, or which area of subject really stimulates them. At this stage, cultivating a personal interest is primary, thus students are supposed to contact with varied areas of knowledge as more as possibly. Since when they don't like one kind of the subjects, they can shift their attention to another until finding one that the most suitable. Take my cousin as an excellent example, he was absolutely tired of what has been taught, like math or science. He squandered his valuable time by taking a nap when attending a class or even truancy. Everything had changed, however, when there were more kinds of courses offered in school, he eventually knew about what is his "true love" - that means my cousin had found what really want to do after all. For tertiary-level students, when graduated from high school, they have to make the choices what they will develop in the universities. " Universities are the place where to train talents for society.", my major professor often said. Therefore, we have to make further efforts on our majors, and by having a good command of one specific subject, definitely, we will get more employable skills which are exactly helpful for jobs.
