09年中科院考博英语作文题目
非常惭愧,没有完全明白作文题目的意思：
Should there be two focuses available in Chinese high-school education(humanity focus and science focus)?
1.请翻译这句话。
2.在这句话中，available怎么理解？humanity focus,science focus怎么理解？个人理解是文科、理科，也有人认为是以道德教育为中心、以素质教育为中心。
3.字典中，复数humanities才是人文社科。单数是否也可以是人文社科？请给出依据。

Open Mind
Open mind generally means positive and creative thoughts. Sometimes we might come into such case that a tough problem difficult to solve in a certain method can be easily setteled in another, but all too often, we do almost everything in our traditional ways rather than serch for any alternatives and at last only to find we have missed many opportunities. From the above case we can have a visible idea of what and how important open mind is.
Open mind can bring us a lot benefits. In the first place, open mind keeps our thoughts positive. As we have now entered information age, we can help ourselves keeping up with the times with an open mind by updating our knowledge structure with the aid of various data sources from books to newspapers and from television to internet. In the second place, open mind keeps our thoughts creative. When our mind keeps open, the traditonal ideals,behaviours as well as rules are likely to be questioned for their reasonableness and therefore we can dispose of those that restrain our development, and furthermore, explore more unknown fields and make more innovations.
Of course, recognizing the importance of open mind is only the first step to success and we have to put it into practice in our daliy activities as well. Take an example, for students ,they should learn more and think for themselves instead of merely holding what their teachers tell them, while for scientists, it is necessary for them to try new models and techniques rather than just follow the convention they are familiar with.
In short, remember to keep your mind open, catch as many opportunities as possible if you want to achieve greater success.
