    Henry Ford was born on a farm on July 30th, 1863. The farm was near the city of Detroit.

    Henry was always interested in machines. He enjoyed fixing clocks.And he helped repair farm equipment. When Henry was sixteen years old, he left the family farm and went to Detroit to learn more about machines. Henry used what he learned from work to develop engines. In 1903, he was ready to start building cars for the public. On July 15th, 1903, a man named Doctor Pfenning bought the first car from the Ford Motor Company.

    The sale to Doctor Pfenning was the beginning of a huge number of requests for Ford cars.By the end of March, 1904, almost 600 Ford cars had been sold. At the start of 1905, the Ford Motor Company was producing 25 cars each day.

    Henry Ford was sure the future of the automobile industry was in a low-priced car for the general public. He said then, and many times after,“I want to make a car that anybody can buy.”

    In 1907, Henry Ford said: "I will build a motor car for the great mass of people. 1t will be large enough for the family, but small enough for one person to operate and care for. It will be built of the best materials. It will be built by the best men to be employed. And it will be built with the simplest plans that modern engineering can produce. It will be so low in price that no man making good money will be unable to own one.”

细菌也有益

    ①人们都喜欢用美妙的词句、动人的诗篇去赞美那些湖光山色、花香鸟语，却很少有人赞美过细菌。一提起细菌，人们总会预感到一种不祥之意，因为它能传染疾病，给人们带来痛苦。可是，谁又能想到细菌也有有益的一面呢？

    ②在日常生活中，我们每时每刻都在跟细菌打交道。细菌非常微小，只有在显微镜下才能看见。可是有些细菌对人类却起了重大作用。譬如，在工业上，可以利用细菌勘探石油；在日常生活中，像我们食用的醋泡菜和我们饮用的红茶菌，都是用细菌制成的；还有农作物生长也离不开细菌。大家知道农作物要想长好，土壤必须肥沃，而土壤的肥沃就是靠有些细菌来发挥作用的。

    ③关于土壤中细菌的作用，科学家曾经做过这样的观察：在1克重的土壤中有1亿到几十亿个生物，其中大部分是细菌。土壤细菌能把土壤中不能被植物直接吸收的养料分解成植物所需的物质。另外，土壤细菌还能制造各种抗生素和微生素，帮助植物抵抗病菌，促进植物生长。但是也有些细菌对植物有害，它们能吞食养料分解成异物，使土壤板结。

    ④因此，我们要消灭有害细菌，确保有益细菌的生长和繁殖，充分发挥它对人类的作用。不久的将来，一定会有更多的细菌被人们开发和利用。
