Careful and Careless　　Careful and careless are as different as fire and water. But strangely, many scientists have both these qualities, that is, they are both careful and careless. Newton, the well known English scientist, is such a person.　　Once Newton invited a friend to dinner at home. When they were ready to eat, Newton left to get a bottle of wine. But after his friend had waited for a long time, Newton still didnt come back. Finally his friend found Newton in his lab. The reason was that when Newton was going to get the bottle of wine, he suddenly had a new idea for the experiment he was doing, so he completely forgot his friend and the dinner. There was another time when Newton was leading a horse up a mountain holding the rein in his hand. While he was walking, he kept thinking of problems he had met in his studies. When he got to the top of the mountain, he found that the rein was not in his hand and the horse was gone.　　Many scientists are careless about how they live. This is because they are too careful in their studies.　　細心和粗心是我們經常要談到的話題。一般人一想到這個話題，就會從細心的好處，粗心的壞處開始議論，而本文作者卻別具匠心，用大科學家牛頓的例子來說明這兩種水火不容的品格是如何集于一人之身。其實現實生活中也不乏這樣的例子。讀者從此文中應學的東西是作者不同尋常的構思。　　細心與粗心　　細心與粗心，就像火與水一樣的不同。然而奇怪的是，許多科學家都有這方面的特點。換句話說，他們既粗心，也細心。英國著名的科學家牛頓，就是這樣一個人。　　曾經有一次，牛頓邀請一位朋友到家吃飯。當他們準備好吃飯時，牛頓離開飯桌去拿一瓶酒。可是他朋友等了好久，也沒有見牛頓出來。最后他朋友發現牛頓在實驗室里。原來牛頓去拿酒時，突然對他正在做的實驗產生了新的想法，因此，他把他朋友和飯全忘了。還有一次，牛頓趕著一匹馬上山，手里抓著韁繩。他邊走，邊想著他在研究中所遇到的問題。當到山頂時，他發現韁繩已不在手里，馬也不見了。　　許多科學家在生活中都很粗心。那是因為他們在工作中太細心了。
