The TV? The printer? The telephone? Or the computer? A report shows that these are not the only important inventions. Here are four other important ones. Paper is one of the most important inventions. You can’t have printing without paper. In 105 AD, Cai Lun invented paper in China. Long before the printer and Internet, Cai Lun’s invention allowed us to write down information, stories and history. One of the simplest inventions to save life is the toilet. Before toilet, waste ran into the rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water. Animal food is another invention. Before the invention, most animals were killed every autumn because there was not enough food for them in the winter. After hay (牧草) became a kind of common animal food, animals could live through the long winter. Reading glasses is the fourth invention. People start getting farsighted from the age of 45. Glasses mean that anyone can read, write, and do “close work” after that age. Without glasses, the world would be difficult for people above 45. 21．Cai Lun’s invention of paper makes it possible to ________. A．have printing B．feed animals C．drink clean water D．do “close work” 22．The invention of the toilet can stop people from ________ so easily. A．saving water B．getting ill C．living in big cities D．finding clean water 23．Why couldn’t the animals live through the winter? A．It was very cold in winter. B．They didn’t have enough food to eat. C．They had no drinking water. D．They died of illness. 24．What does the underlined word “farsighted” mean according to your understanding?

A．all people need reading glasses B．anyone must do “close work” after 45 C．reading glasses are useful D．life is more difficult for the people under 45 【答案】21．A 22．B 23．B 24．A 25．C 【导语】这是一篇说明文。文章主要介绍了2000年以来人类最重要的几项发明，即蔡伦的造纸术、厕所、动物食物和老花镜的发明。 21．推理判断题。根据第二段中“You can’t have printing without paper. (没有纸就没有印刷。) ”可推知，蔡伦发明了纸，使印刷成为了可能。故选A。 22．细节理解题。根据第三段中“Before toilet, waste ran into the rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water. (在使用厕所之前，人们家中的排泄物会流入河流。在大城市，疾病十分常见，而且往往很难找到干净的饮用水。)” 可知，厕所的发明使人们不再那么容易生病。故选B。 23．细节理解题。根据第四段中“Before the invention, most animals were killed every autumn because there was not enough food for them in the winter. (在发明这项技术之前，大多数动物每年秋天都会被宰杀，因为冬季时它们没有足够的食物可吃。)”可知，这些动物无法熬过冬天是因为它们冬天没有足够的食物吃。故选B。 24．词句猜测题。根据最后一段中“People start getting (人们开始变得) ”和“from the age of 45 (从45岁)”以及“Glasses mean that anyone can read, write, and do “close work” after that age (眼镜意味着在那个年龄之后，任何人都能够阅读、书写并进行近距离工作了。)”可知，戴老花镜意味着过了这个年龄，任何人都能读、写、做“近距离工作”，可推测出，“farsighted”指看不清近物，即“远视”。故选A。 25．推理判断题。通读最后一段和“Glasses mean that anyone can read, write, and do “close work” after that age. (眼镜意味着在那个年龄之后，任何人都能够阅读、书写并进行近距离工作了。)”可推知，老花镜很有用。故选C。 三、补全对话（共5小题，每小题3分，共15分） 根据对话内容，从文后选择恰当的选项补全对话，其中有两项多余。 Mary: What’s up? You look really sad. Kate: 26 Mary: What’s wrong? Tell me about it.
