B. The speech proposes and expounds on the duties of a scientist in the modern age. Advancing science and technology have brought about drastic changes to our everyday life, but have
also given rise to serious worldwide problems. As a result, modern scientists are burdened with increasingly heavy responsibilities in addressing such big issues as population control, nuclear weapon checks and imbalance between plenty and poverty. In order to undertake research, scientists need a proper environment in which they are guaranteed the freedom to work for public welfare. Therefore, scientists can be of great service to mankind in achieving peace and freedom.
C. (1) The goal for the twenty-f irst century is to create a world of informed and engaged citizens committed to creative public service. (2) Experimentation is the best test.

Reading about the Topic
3. 1) The article mainly tells us that the discovery of penicillin needs a prepared and open mind, and also relevant knowledge is essential for scientific investigation. 2) Only when bacterial colonies are quite young. 3) At least four.

2) Keeping an open mind ready to exploit new possibilities and connect the dots.
3) An open mind would enable one to see something in a new light, therefore connecting it to other phenomena to explain the causes and fully reveal significances.
4) Yes. They may share the same background as the themes of the two articles both revolve around medical research.
9. 1) Accidental connection of dots led to the discovery that vaccination is a general method for preventing infectious diseases. (Para. B)
2) However, the dispute changes neither the significance of the discovery nor its accidental nature. (Para. C)
3) Smallpox vaccination was accepted strictly based on empirical success and as such it did not point to the possibility of vaccines for other diseases. (Para. D)
4) One no longer needs to wait for a lucky observation to suggest a vaccine for a specif ic disease. (Para. E)
5) Experiments are not passive observations; they are actively planned according to some conception to look for something. (Para. F)
10. Connecting the dots or making connections between different phenomena, though entailing more knowledge and insight, will lead to a more significant discovery. Exploring the Topic
4. 1) However, discovering the room that hides more doors leading to even greater treasures involves an open mind ready for new possibilities and connecting the dots.
2) Fleming was totally capable of conducting many animal experiments which required little chemical background. 3) Normally one’s own resources can be supplemented with seeking collaborators or employing assistants.
4) Neither the significance of the discovery nor its accidental nature can be altered by the dispute.
5) Often it is not until someone examines a previous phenomenon from a new perspective and sees its significance that chance discoveries are made. Integrated Exercises

B. David Ellyard believes that discoveries in science originated in Italy in the early 16th
century. From there and then, we can trace a steady and ever-growing stream of discoveries about the workings of the natural world. Certainly there were sources further back, but many remained unknown. Both in China and Arabia, the spirit of free inquiry, the essential nutrient of science, had been crushed by centralized governments. And he thinks the most important discovery of all, the one that supports all the rest, was how to do science.
