71.Our first reaction to the suggestions was one of utter astonishment. Nonetheless，simply discussing related issues suggests a starting point for finding solutions.
72.What does the future hold if mankind persists in wasting natural resources? While no one knows for sure，scientists do exhibit a degree of certainty when predicting that future generations will face a dramatically different world.
73.Reversing undesirable social trends will be far from an easy task and will require a dramatic change in attitudes. A keen awareness of right from wrong is essential for determining appropriate social behavior.
74.Achieving the impossible is quite obviously an oxymoron(figure of speech that uses seeming contradictions).Therefore，succeeding at a difficult task requires great effort.
75.We owe a debt of gratitude to the many individuals who dedicated their lives to making the world a better place. However，we must not rest on their accomplishments，but must instead work assiduously to record even greater achievements.
76.There are indeed many problems requiring urgent attention，but concerted efforts on our part will eventually lead to final solutions.
77.The two major challenges facing China today center on maintaining sustained economic growth and feeding its growing population of over1.2 billion people with only seven percent of the world s cultivable land. Despite the monumental difficulties involved，Chinese people will undoubtedly exhibit their indefatigable resilience and achieve great success in both regards.
78.We do，in fact，have a long way to go to reach our final goal
，but achieving some remains well within the realm of possibility.
79.The time is right for us to take full advantage of ample existing opportunities.
80.While it remains to be seen whether or not environmental deterioration can be controlled，the current prospects are far from encouraging. People around the world must act immediately to prevent the situation from deteriorating even further.
81.The methodology suggested may not guarantee ultimate success，but the eventual pay-off could well be worth the effort. Achieving even partial success will benefit mankind and contribute to creating a better world.
82.Admittedly，ensuring sustainable development will require a certain level of sacrifice and arduous efforts on the part of all people. Nonetheless，the accrued returns will both strengthen the nation and ensure a better life for all Chinese citizens.
83.The importance of physical exercise cannot be overemphasized. Exercise can and will improve one s sense of well-being，enhance mental capacity and improve stamina.
84.The rapid emergence of homes for senior citizens represents a s
harp divergence from the traditional Chinese practice of maintaining the nuclear family at all costs.
85.Participating in interactive experiences beneficial to all is something that no one should miss. The valuable lessons learned there-from
should not be arbitrarily dismissed，but should instead be treasured.
86.We are entering a new era which requires continuing personal sacrifices which will yield eventual rewards.
87.Abortion advocates may be correct in their assertion that the practice is a necessary tool of population control，but they seem to neglect the preciousness of human life in its earliest stages.
88.“Self-indulgence is the root of all evil!” Individuals must totally abandon the concept of personal gain for the benefit of mankind.
89.How often have we heard the admonition that “All men are created equal!” It s high time to achieve，rather than simply talk about the lofty goal.
90.“Today is the first day of the rest of your life!” People must gain a true understanding of the statement and proceed to abandon old habits in order to embark on the road to new achievements.
91.P.T.Barnums assertion—“There s a sucker born every day!”—is undeniably true. The proof s in the pudding when one considers the gullibility of modern-day consumers.
92.A great thinker in times past postulated that the World was flat. Some people(i.e. The Flat Earth Society)persist in the belief in spite of indisputable evidence to the contrary.
93.Some people assert that nothing is impossible. Such people should g
et a grip on reality and understand it s impossible to create another Universe. In more down-to-earth terms，it s impossible to know with any certainty whether you will live or die tomorrow.94.Can anyone doubt that full consideration of the facts readily proves the impossibility of achieving a global Utopia?
95.Two major factors contributed to devastating summer flooding along the Yangtze River and its tributaries. First，erosion resulting from excessive deforestation in the upper reaches of the river and， second，
heavy silting which raised the riverbed in the main channel.
96.Greed and a total lack of social consciousness have been cited a
s major reasons for the dramatic rise in corruption.
97.There are several reasons for the marked increase in China s crime rate-the dramatic influx of itinerant workers in urban areas; declining social values; and widening disparities between the haves and have-nots.
98.Why are an increasing number of elderly Chinese parents living apart from their children? One reason is the increasing upward mobility of the younger generation. Another is expanding social opportunities for the elderly. Perhaps the main reason，however，centers on dramatic changes in traditional concepts.
99.What has sparked the increasing interest in exercise? For one thing，people have gained a greater awareness of the need for physical fitness. For another，the constantly improving standard of living enables Chinese people to patronize the increasing number of recreational venues. The main thing perhaps centers on the healthcare and psychological benefits exercise provides.
100.Identifying the reasons for an emerging phenomenon which involves several complicated factors is far from an easy task. For example，some scientists attribute environmental deterioration to a series of natural factors，while others place the blame solely on inappropriate human behavior.
