Development and the Environment
It is undeniable that the worsening environment has become the biggest concern of the present-day world. Land resources are dwindling because of water loss and soil erosion. Waste gases poison the air we breathe. The rivers and lakes are polluted by waste dumped in them from factories. It is probably no exaggeration to say that deterioration of the quality of the environment threatens the existence of mankind itself.
Some people are of the opinion that the environmental problem is the price we have to pay for economic development. But I do not think that this argument is valid. After all, what is the point of economic growth if people's lives are adversely alfected by worsening environmental pollution?
If I speak in the tongues of men and of angels, but have not love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing.
There is plenty of evidence to show that sustainable development can be achieved by balancing economic growth with protection of the environment. The key to achieving this is to make people aware of the seriousness of the problem. Both governments and ordinary citizens should join hands to make this world a better place to live in, not only for ourselves, but also for future generations.
now if all this is true, then why are we getting it so wrong? why are we setting up our schools this way and our workplaces? and why are we making these introverts feel so guilty about wanting to just go off by themselves some of the time? one answer lies deep in our cultural history. western societies, and in particular the u.s., have always favored the man of action over the man of contemplation and “man“ of contemplation. but in america's early days, we lived in what historians call a culture of character, where we still, at that point, valued people for their inner selves and their moral rectitude. and if you look at the self-help books from this era, they all had titles with things like “character, the grandest thing in the world.“ and they featured role models like abraham lincoln who was praised for being modest and unassuming. ralph waldo emerson called him “a man who does not offend by superiority.“
but then we hit the 20th century and we entered a new culture that historians call the culture of personality. what happened is we had evolved an agricultural economy to a world of big business. and so suddenly people are moving from small towns to the cities. and instead of working alongside people they've known all their lives, now they are having to prove themselves in a crowd of strangers. so, quite understandably, qualities like magnetism and charisma suddenly come to seem really important. and sure enough, the self-help books change to meet these new needs and they start to have names like “how to win friends and influence people.“ and they feature as their role models really great salesmen. so that's the world we're living in today. that's our cultural inheritance.
now none of this is to say that social skills are unimportant, and i'm also not calling for the abolishing of teamwork at all. the same religions who send their sages off to lonely mountain tops also teach us love and trust. and the problems that we are facing today in fields like science and in economics are so vast and so complex that we are going to need armies of people coming together to solve them working together. but i am saying that the more freedom that we give introverts to be themselves, the more likely that they are to come up with their own unique solutions to these problems.
so now i'd like to share with you what's in my suitcase today. guess what? books. i have a suitcase full of books. here's margaret atwood, “cat's eye.“ here's a novel by milan kundera. and here's “the guide for the perplexed“ by maimonides. but these are not exactly my books. i brought these books with me because they were written by my grandfather's favorite authors.
can money buy happiness?
can money buy happiness? different people have different opinions. somethink yes, while others hold the opposite.
it is true that with enough money one can buy all the things one wants, andlive a life of comfort and security. however, it is equally true that lack ofmoney causes great distress. it is a common view that "money is the root of allevil." the pursuit of money drives many people to cheat and steal. in someplaces there is nothing that cannot be bought with money, resulting in corruptsocieties where everybody is miserable.
so, money does not necessarily mean happiness. it all depends on how it isused. if we make honest and sensible use of money, it can be a stepping-stone tohappiness l although money cannot buy happiness, it can make happiness possibleif it is employed sensibly.
金钱能买来幸福吗?
金钱能买来幸福吗?不同的人有不同的回答。有的人认为能，有的人则持相反的意见。
诚然一个人如果有足够的钱可以买到他想要的所有物品，过上舒适稳定的生活。然而，同样缺钱往往引起巨大的忧伤。人们常常认为“金钱是万恶之源”，对金钱的追求驱使许多人去骗去偷。在某些地方，没有钱买不到的东西，导致社会的腐化堕落。
所以，金钱并不一定就意味着幸福。这取决于怎样使用金钱，如果我们诚信明智地使用金钱，它将是幸福的基石。尽管金钱买不到幸福，但它可以使幸福成为可能。

吸烟与健康
现在，吸烟是一个世界范围的习惯，不仅老年人、青年人吸烟，就连中学生也加入到这个行列中来，他们中的许多人认为吸烟是一种潇洒的象征。
然而，吸烟对人的健康是有害的，它会引起肺癌，在刚刚过去的几年中;许多人因此而丧命，还可能引发其他的疾病。总之，如果你吸烟的话，你就很可能失去拥有健康的机会，更进一步说，科学研究显示，吸烟不仅危害吸烟者本人，而且对公共健康来说，也是一个凶兆，尤其是对妇女和孩子。因此，许多国家都制定了不准在公共场合吸烟的法规，例如：电影院，车站，医院等地。
戒烟吧，如果你还未染上，请不要开始;戒烟吧，为了你的健康，为了你的家庭的健康，为了整个世界的健康。

环境与发展
不可否认的是环境恶化已成为当今世界上人们最担心的事了。因为水资源的浪费和土壤被侵蚀，土地资源逐渐缩小。我们呼吸着有毒的空气，河流和湖泊也被附近的工厂里排放出来的废弃物严重污染了。不夸大其词地说，环境质量的恶化很可能威胁人类的生存。
有些人说环境问题是我们为经济发展所付出的代价。对此，我不敢苟同。如果人类的生活被日益恶化的环境污染所影响的话，那么，经济发展的意义何在?
足够的证据表明：经济发展与环境保护的平衡可以实现可持续发展。关键是使人们意识到问题的严重性。政府和普通市民两方都应该携手使地球成为更适合人类居住的地方，这不仅是为我们自己，也是为我们的后代。
