Issue 1 Too much emphasis is placed on role models. Instead of copying others, people should learn to think and act independently and thus make the choices that are best for them. Issue 2 In most professions and academic fields, imagination is more important than knowledge. Argument It is known that in recent years, industrial pollution has caused the Earth's ozone layer to thin, allowing an increase in the amount of ultraviolet radiation that reaches the Earth's surface. At the same time, scientists have discovered, the population of a species of salamander that lays its eggs in mountain lakes has declined. Since ultraviolet radiation is known to be damaging to delicate tissues and since salamander eggs have no protective shells, it must be the case that the increase in ultraviolet radiation has damaged many salamander eggs and prevented them from hatching. This process will no doubt cause population declines in other species, just as it has in the salamander species. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.229.168.138
