　　ISSUE:

　　TOPIC 1: 167. "It is impossible for an fective political leader to tell the truth all the time. Complete honesty is not a usul virtue for a politician."

　　对于一个英明的政治领导者来说，总是坦白是不可能的。彻底的诚实对于一个政治家来说是无用的美德。

　　TOPIC2: 69. "Government should place few, if any, restrictions on scientific research and development"

　　政府应该少限制科学研究和发展。

　　ARGUMENT: 207.It is knownthat in recent years, industrial pollution has caused the Earth&aposs ozone layerto thin, allowing an increase in the amount of ultraviolet radiation thatreaches the Earth&aposs surface. At the same time, scientists have discovered, thepopulation of a species of salamander that lays its eggs in mountain lakes hasdeclined. Since ultraviolet radiation is known to be damaging to delicatetissues and since salamander eggs have no protective shells, it must be thecase that the increase in ultraviolet radiation has damaged many salamandereggs and prevented them from hatching. This process will no doubt causepopulation declines in other species, just as it has in the salamander species.
