①人们常常把人与自然对立起来，宣称要征服自然。殊不知在大自然面前，人类永远只是一个天真幼稚的孩童，只是大自然机体上普通的一部分，正像一株小草只是她的普通一部分一样。如果说自然的智慧是大海，那么，人类的智慧就只是大海中的一个小水滴，虽然这个水滴也能映照大海，但毕竟不是大海，可是，人们竟然甲地宣称要用这滴水来代替大海。

    ②看着人类这种狂妄的表现，大自然一定会窃笑——就像母亲面对无知的孩子那样的笑。人类的作品飞上了太空，打开了一个个微观世界，于是人类乙，以为揭开了大自然的秘密。可是，在自然看来，人类上下翻飞的这片巨大空间，不过是咫尺之间而已，就如同鲲鹏看待斥鹅一般，只是蓬蒿之间罢了。即使从人类自身智慧发展史的角度看，人类也没有理由丙：人类的知识与其祖先相比诚然有了极大的进步，似乎有嘲笑古人的资本；可是，殊不知对于后人而言我们也是古人，一万年以后的人们也同样会嘲笑今天的我们。也许在他们看来，我们的科学观念还幼稚得很，我们的航天器在他们眼中不过是个非常简单的儿童玩具。人类的认识史仿佛是纠错的历史，一代一代地纠正着前人的错误，于是当我们打开科学史的时候，就会发现科学史也是犯错误的历史。那么             ？

    ③人类发明了种种工具，挖掘出大自然用亿万年的时间积累下来的宝藏——一煤炭、石油、天然气以及其他各种矿物，人类为自己取得这些成就而丁，然而，谁能断言那些狼藉斑斑的矿坑不会是人类自掘的陷阱呢？

     ④在宇宙中，一定存在着远比我们的智慧要高得多的生物，因为我们的太阳系只有40多亿年的历史，就演化出了有智慧的生物，而宇宙至少已有200亿年的历史了。可以推想，在那些比太阳系更古老的星系里，一定早就演化出了更高级的生物。这些生物的智慧也许是我们所无法比拟的。他们看我们，也许就像我们看蚂蚁一般，即使我们中间的那些伟大人物，在他们看来也不过尔尔。

    When I was in my twenties, I travelled alone through the UK. In order to 1 locations that the public transportation couldn't get to, I bought a(n)2 car, drove it around for three months and sold it before I returned to Australia. The car cost most of my money, so I lived mainly on3during that trip, it being cheap and filling. In Ireland, my4 was stolen, and it was impossible to get another. So for the rest of the trip I 5out in my car, being too poor to afford bed and breakfast.

    One morning, I 6 in my old Skoda under a twisted tree on a remote lane in the Irish countryside, with no more than a 7 house in sight. I had a terrible desire for a 8 cup of tea and some hot water to make porridge with 9 I would not have to eat the cold leftovers from the previous day.

    My thermos (暖瓶) had gone cold overnight so I knocked on the door of the house. A woman opened it. Hot water? She 10 let me get away with just that! I was invited indoors, seated at the breakfast table with the 11 and given a delicious breakfast, as much as I could eat. I was 12 to eat something more than porridge! I 13 being friends with the whole family.

    That was only one of many acts of 14strangers showed me when I was traveling alone in foreign regions. One London businessman rushing to work, seeing me 15 offered to pull my ridiculously heavy suitcase 16several flights of stairs in the underground. After he'd done so, with a smile and a wave, he 17 into the crowd.

    Kindness gets 18. The other day, I was able to point out a rare parking spot to a young man who had been driving around the railway car park, looking 19 desperate. His grateful smile was all the 20 I needed as I dashed off to catch my train.
