Band-Aids（创可贴） The first Band-Aid was made by American Earle Dickson in 1921. The idea came to him by chance. Dickson’s wife Josephine often cut her fingers in the kitchen. At that time gauze（纱布） and adhesive tape（胶带）didn’t come together. People had to cut them to the right size. Dickson found they were always too big and soon fell off. So he put a piece of gauze on the center of a piece of tape. This is how he made the first Band-Aid. Later Dickson’s new inventions became very popular all around the world Bubblegum（泡泡糖） Bubblegum was invented by accident. In 1928, American gum company worker Walter E. Diemer played around with new chewing gum recipes. Chewing gum had already been invented more than half a century before then. But Diemer found that the gum he made was easy to blow. He blew a bubble and then saw the possibilities. He took some of his new gum to a shop and it sold out in a single afternoon. Since then, Dubble Bubble—the first brand of bubblegum—has made kids happy all around the world. 51．Josephine often _________ in the kitchen. A．hurt her fingers B．made bubblegum C．played with new recipes D．cut gauze to the right size 52．Before the Band-Aid was invented, _________. A．the gauze and adhesive tape were always small B．people had to cover the cut with a piece of cloth C．people had to be careful to cut the gauze quite big D．people had to cut the gauze and adhesive tape to the right size 53．Bubblegum was invented by an _________. A．American doctor B．American gum company worker C．American housewife D．American gum shopkeeper 54．Bubblegum was invented around _________ years after chewing gum was invented. A．30 B．50 C．80 D．100 55．Diemer’s bubblegum sold out during _________. A．a day B．a morning C．an afternoon D．two days 【答案】51．A 52．D 53．B 54．B 55．C 【分析】文章大意：本文介绍了日常生活中的两项发明——创可贴和泡泡糖。第一个创可贴是在1921年由美国的Earle Dickson发明的。泡泡糖是于1928年由美国的一家口香糖公司的工人Walter E. Diemer 发明的。 51．细节理解题。根据文中的信息Dickson’s wife Josephine often cut her fingers in the kitchen.可知，Dickson的妻子Josephine经常在厨房里弄伤手指，故答案选A。 52．细节理解题。根据文中的信息At that time gauze（纱布） and adhesive tape（胶带）didn’t come together. People had to cut them to the right size.可知在创可贴被发明前，人们必须把纱布和胶带剪成合适的尺寸，故答案选D。 53．细节理解题。根据文中的信息Bubblegum was invented by accident. In 1928, American gum company worker Walter E. Diemer played around with new chewing gum recipes.可知泡泡糖是由一个口香糖公司的工人发明的，故答案选B。 54．推理判断题。根据文中的信息Chewing gum had already been invented more than half a century before then.可知，口香糖在半个多世纪之前就发明了，所以泡泡糖应是在口香糖发明50年后发明的；故答案选B。 55．细节理解题。根据文中的信息He took some of his new gum to a shop and it sold out in a single afternoon.可知，Diemer的泡泡糖在一个下午就卖完了，故答案选C。 B Nobody knows who invented the pencil or when it was invented. A Swiss described a pencil in a book in 1565. He said it was a piece of wood with lead（铅）inside it. In 1795，someone started making pencils from graphite（石墨）and they became very popular. Today，people make pencils in the same way. They put it inside a piece of wood. One pencil can make a line as long as 55 kilometers. When people wrote with pens，they had to put the pen point into the ink after writing every few letters. Later someone invented a fountain pen（自来水笔）and this kind of pen could hold ink inside it. A fountain pen can write several pages before you have to fill it again. Two brothers，Ladislao and Georg Biro，invented the ballpoint pen that we all use today. They left their country Hungary and started producing ballpoint pens in England in 1943 during the World War Ⅱ. Later，a French company called Bic bought the Biro brothers' company. Someone calls ballpoint pens bics. Australians call them biros. Whatever they are called，we use them every day. 56．When was the pencil invented according to the passage？ A．In 1565. B．In 1795. C．In1943. D．Before1565. 57．What do people use to make pencils today？ A．Graphite. B．Steel. C．Ink. D．Stone. 58．What does the underlined word “pen point” mean in Chinese？ A．笔杆 B．笔帽 C．笔尖 D．笔筒 59．Where were Ladislao and Georg Biro from？ A．America. B．Australia. C．Hungary. D．England. 60．What is the passage mainly about？ A．Some famous inventors. B．The invention of pencils and some kinds of pens. C．Who invented the pencil. D．Which kind of pen is the most useful. 【答案】56．D 57．A 58．C 59．C 60．B 【分析】本文讲述了“笔”的发展，首先是铅笔，然后是钢笔，后来又发明了自来水笔，最后是我们每天都在使用的圆珠笔。 56．细节理解题。题意：根据文章，铅笔是什么时候被发明的？根据A Swiss described a pencil in a book in 1565. He said it was a piece of wood with lead（铅）inside it.可知，有人在1565年的一本书里描述了铅笔，说明在此之前铅笔已经问世，故本题选D。 57．细节理解题。题意：现在人们用什么来制作铅笔？A. Graphite.石墨；B. Steel.钢；C. Ink.墨水；D. Stone.石头。根据In 1795，someone started making pencils from graphite（石墨）and they became very popular. Today，people make pencils in the same way.故选A。 58．词意猜测题。题意：下划线“pen point”的中文意思是什么？根据When people wrote with pens，they had to put the pen point into the ink after writing every few letters. 当人们用钢笔写字时，他们每写几个字就得把笔尖放进墨水里。我们知道，一支笔是笔尖部分写出字，故选C。 59．细节理解题。题意：Ladislao和Georg Biro来自哪里？A. America.美国；B. Australia.澳大利亚；C. Hungary.匈牙利；D. England.英国。根据Two brothers，Ladislao and Georg Biro，invented the ballpoint pen that we all use today. They left their country Hungary可知，这两人来自匈牙利，故选C。 60．主旨大意题。题意：文章主要关于什么？A. Some famous inventors.一些著名的发明家。B. The invention of pencils and some kinds of pens.铅笔和一些笔的发明。C. Who invented the pencil. 谁发明了铅笔。D. Which kind of pen is the most useful. 哪种笔最有用。本文主要讲了铅笔和其他的笔的发明，故选B。 C 配对阅读：左栏是五个人的情况简介，右栏是七种发明，请将这五个人与他们所使用的发明配对。 61 Rocky keeps a dog that has long hair.

Band-Aids（创可贴） The first Band-Aid was made by American Earle Dickson in 1921. The idea came to him by chance. Dickson’s wife Josephine often cut her fingers in the kitchen. At that time gauze（纱布） and adhesive tape（胶带）didn’t come together. People had to cut them to the right size. Dickson found they were always too big and soon fell off. So he put a piece of gauze on the center of a piece of tape. This is how he made the first Band-Aid. Later Dickson’s new inventions became very popular all around the world Bubblegum（泡泡糖） Bubblegum was invented by accident. In 1928, American gum company worker Walter E. Diemer played around with new chewing gum recipes. Chewing gum had already been invented more than half a century before then. But Diemer found that the gum he made was easy to blow. He blew a bubble and then saw the possibilities. He took some of his new gum to a shop and it sold out in a single afternoon. Since then, Dubble Bubble—the first brand of bubblegum—has made kids happy all around the world. 51．Josephine often _________ in the kitchen. A．hurt her fingers B．made bubblegum C．played with new recipes D．cut gauze to the right size 52．Before the Band-Aid was invented, _________. A．the gauze and adhesive tape were always small B．people had to cover the cut with a piece of cloth C．people had to be careful to cut the gauze quite big D．people had to cut the gauze and adhesive tape to the right size 53．Bubblegum was invented by an _________. A．American doctor B．American gum company worker C．American housewife D．American gum shopkeeper 54．Bubblegum was invented around _________ years after chewing gum was invented. A．30 B．50 C．80 D．100 55．Diemer’s bubblegum sold out during _________. A．a day B．a morning C．an afternoon D．two days B Nobody knows who invented the pencil or when it was invented. A Swiss described a pencil in a book in 1565. He said it was a piece of wood with lead（铅）inside it. In 1795，someone started making pencils from graphite（石墨）and they became very popular. Today，people make pencils in the same way. They put it inside a piece of wood. One pencil can make a line as long as 55 kilometers. When people wrote with pens，they had to put the pen point into the ink after writing every few letters. Later someone invented a fountain pen（自来水笔）and this kind of pen could hold ink inside it. A fountain pen can write several pages before you have to fill it again. Two brothers，Ladislao and Georg Biro，invented the ballpoint pen that we all use today. They left their country Hungary and started producing ballpoint pens in England in 1943 during the World War Ⅱ. Later，a French company called Bic bought the Biro brothers' company. Someone calls ballpoint pens bics. Australians call them biros. Whatever they are called，we use them every day. 56．When was the pencil invented according to the passage？ A．In 1565. B．In 1795. C．In1943. D．Before1565. 57．What do people use to make pencils today？ A．Graphite. B．Steel. C．Ink. D．Stone. 58．What does the underlined word “pen point” mean in Chinese？ A．笔杆 B．笔帽 C．笔尖 D．笔筒 59．Where were Ladislao and Georg Biro from？ A．America. B．Australia. C．Hungary. D．England. 60．What is the passage mainly about？ A．Some famous inventors. B．The invention of pencils and some kinds of pens. C．Who invented the pencil. D．Which kind of pen is the most useful. C 配对阅读：左栏是五个人的情况简介，右栏是七种发明，请将这五个人与他们所使用的发明配对。 61 Rocky keeps a dog that has long hair. He loves it very much and washes its hair twice a week. After washing it, he will use a kind of equipment to dry its hair. 62 Tina watches TV every night, so do her parents. But there is only one television in her home and she and her parents watch different programs. Most of the time, she watches TV shows online. 63 John is a shop worker. He is always busy, and he hardly has time to cook. Usually, he buys some instant (即食的) food after work and heats it at home. 64 Edward is a little overweight. He hates hot summer days. On these days, he will use a kind of equipment to keep himself cool. What’s more, he can also use it on cold winter days. 65 Judy has a big family, and she has to cook a lot of food for her husband and children every day. However, on summer days, food easily goes bad, so she uses a kind of equipment to keep it fresh. A．FridgeIt is a kind of cooling equipment and a modern invention used in kitchens.
