漫画《谁先到终点》大船用船上的鼓风机吹帆做为动力,小船上的人用力划桨做为动力,假设无风且水面静止,关于两船的运动说法正确的是(  )

A.由于大船大,受到的阻力大,所以后到达终点

B.大船上的帆与鼓风机连成一个整体,没有施力物体,所以不能前进

C.小船上的人虽然用桨划,但由于船小,所以后到达终点

D.由于不知道两船的速度,所以不能判断

答案

对于大船来说,船上的帆与鼓风机是船上的一部分,它们之间的作用力是整体内部的力,对船来说不起任何作用,所以大船在水平方向上没有受到任何外力,只能处于静止,无法前进;

对于小船来说,当人划桨时,桨对水有一个向后的作用力,由于物体间力的作用是相互的,水对桨也有一个向前的作用力,在这个力的作用下,小船可以前进,并且能到达终点.

综合分析可知选项B是正确的,A、C、D都是错误的.

故选B.

I once had my Chinese MBA students brainstorming on “two-hour business plans”. I separated them into six groups and gave them an example: a restaurant chain. The more original their idea, the better, I said. Finally, five of the six groups presented plans for restaurant chains. The sixth proposed a catering(餐饮) service. Though I admitted the time limit had been difficult, I expressed my disappointment.

My students were middle managers, financial analysts and financiers from state-owned enterprises and global companies. They were not without talent or opinions, but they had been shaped by an educational system that rarely stressed or rewarded critical thinking or inventiveness. The scene I just described came in different forms during my two years’ teaching at the school. Papers were often copied from the Web and the Harvard Business Review. Case study debates were written up and just memorized. Students frequently said that copying is a superior business strategy, better than inventing and creating.

In China, every product you can imagine has been made and sold. But so few well-developed marketing and management minds have been raised that it will be a long time before most people in the world can name a Chinese brand.

With this problem in mind, partnerships with institutions like Yale and MIT have been established. And then there’s the “thousand-talent scheme”: this new government program is intended to improve technological modernization by attracting top foreign-trained scientists to the mainland with big money. But there are worries about China’s research environment. It's hardly known for producing independent thinking and openness, and even big salary offers may not be attractive enough to overcome this.

At last, for China, becoming a major world creator is not just about setting up partnerships with top Western universities. Nor is it about gathering a group of well-educated people and telling them to think creatively. It’s about establishing a rich learning environment for young minds. It’s not that simple.
