transform societies with unprecedented knowledge resources.

However, there are many barriers to knowledge transfer. For example, lack of trust and resistance to change undermine the transfer of knowledge. People are less likely to acquire knowledge from those whom they don’t trust or to adopt new theories and practices they are not familiar with. Cultural and language barriers also hamper the transfer of knowledge between nations or ethnic groups. It would be almost impossible for people who speak different languages or dialects with different cultural backgrounds to communicate effecitvely, not to mention exchanging knowledge.

An underdeveloped economy is another barrier to knowledge transfer. The lack of socio-economic and techno-environmental cooperation, as well as poor communications infrastructure, can greatly hinder the flow of knowledge within and between nations.

To remove these barriers, people should change their attitude towards knowledge transfer and the learning of foreign languages and cultures. At the same time, efforts should be made to develop a better world economy. (190 words) The Answers to Book4---Unit4 Enhance Your Language Awareness

Some people think that they’ve fulfilled their tasks as long as they go on duty and come off duty on time. They never think about what is meant by “work” and why they should work at all. In fact, “work” involves such qualities as wisdom, enthusiam, imagination and creativity.

To do his work well, a worker must have a spirit of dedication, and be

capable of bearing hardships and standing hard work. In addition, he should have initiative and creativity. Having initiative means the worker should be ready to grasp every opportunity to display his outstanding ability.

In addition, a worker should make clear the nature and significance of the work he does, be responsible for whatever he is doing and plunge himself into the work with vigorous enthusiasm. If he can do so, he willl find a job no longer a burden but an indispensable part of his life. Whatever he does, he can always find values and pleasure in the work and achieve extraordinary results in otherwise ordinary work. The Answers to Book4---Unit5 Enhance Your Language Awareness
