4．I was traveling in a small place in New York．That place had no taxi for a short（71）distance（distant）．I needn't （72）have worried（worry） before I got there，for one could take a rickshaw（人力车）．
I called out for an old man in the waiting line．Before I got on the rickshaw，I asked how much he would charge to take me across to the Mall．I （73）was told（tell）"10 dollars"．Then I started bargaining．He just gave a hard smile and said，"whatever you feel like，please give me．It is not necessary（74）to bargain（bargain） on this small amount．"
I was a bit ashamed of （75）whatI did and kept quiet when he continued，"（76）Unlike（like） those taxis，my vehicle does not run on petrol or diesel （柴油） or even gas；（77）itruns on my sweat．"So please give it to me（78）witha smile，for the money has to feed so many（79）hungry（hunger） mouths at home．
When we reached the Mall，I gave him boththe money and the smile．He smiled back and I would preserve his smile for（80）along time．

19．The earth is the only planet that scientists think has life．Why does the earth have life while the other planets （行星） don't？For one thing，the earth is just the right temperature．As the third planet from the sun，the earth seems to be just the right distance away．The planets which are closer to the sun are hot that their surfaces bake （烘烤） in the sun．The farthest planets are cold balls．
When the earth developed，which scientists believe may have happened about 4billion years ago，many gases covered the earth．The gases caused the earth to be hot．But something wonderful happened．The temperature was just right for thick clouds to form．It rained very hard for a very long time．This gave the earth its oceans．Water made it possible for plants to grow．The plants created oxygen in the atmosphere．Oxygen is the gas that humans and animals breathe．
Only one other planet in the solar system seems to be something like the earth．That planet is Mars （火星）．Mars is smaller than the earth，and it is quite a bit cooler．But it is not too cold for humans．On some days，the temperatures are as low as a winter day in the northern United States．If you wore a special space suit，you could walk around on Mars．You would have to bring your own air to breathe，the air on Mars is too thin to breathe．
Mars has the largest volcano （火山） in the solar system．It is sixteen miles high．The highest volcano on the earth is five miles high．The most unexpected （未预测到的） sight on Mars is dried up river beds．Scientists believe that Mars was once much better than it is now．Does this mean there could have been living things on Mars？Scientists are not sure，but there has been no sign so far．

18．The food we eat seems to have profound effects on our health．Although science has made big steps in making food more fit to eat，it has，at the same time，made many foods unfit to eat．Some research has shown that 80percent of all human illness are connected with diet and 40percent of cancer is connected with the diet as well．That food is connected with illness is not a new discovery．In the 1940s scientists realized that nitrates（硝酸盐），which are often used to keep color of meat，and other additives（添加剂）caused cancer．However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful．Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices．For example farmers try hard to make animals grow big so that they can sell the big animals for more money．Although the Food and Drug Administration has tried again and again to control farmers to do so，farmers go on doing this．
