Do you know who invented it? 2 Guess their names and how they were invented Around the World zip eraser pressure-sensitive adhesive 3 Guess their names and how they were invented Around the World The zip has become so common that we almost take it for granted. Whitcomb L. Judson from Chicago is believed to be the “Inventor of the Zip”, but it was actually Gideon Sundback who designed the modern zip. Today the zips produced each year are long enough to stretch around the Earth many times! 文本翻译 4 Guess their names and how they were invented Around the World 拉链如此普遍以至于我们几乎习以为常。来自芝加哥的惠特科姆·L·贾德森被认为是拉链的发明者，但事实上是吉迪恩·桑德巴克设计了现代拉链。现今，每年生产的拉链总长足以绕地球好多圈。 5 Guess their names and how they were invented Around the World Invented in 1770, the eraser is used to erase pencil marks. Before its invention, believe it or not, bread was used to erase pencil marks. Even better, in 1858, Hymen Lipman invented the all-in-one pencil with an eraser. In 1968, a US scientist, Dr Spencer Silver, attempted to develop a super-strong adhesive. However, he accidentally created a reusable, pressure-sensitive adhesive. In 1974, one of his colleagues came up with the idea of using the adhesive to anchor his bookmark. The original notes’ yellow colour was chosen by accident, as the lab next door to the Post-it team had only yellow scrap paper to use. 文本翻译 6 Guess their names and how they were invented Around the World 橡皮发明于1770年，用于擦掉铅笔字迹。不管你信不信，在发明橡皮之前，面包曾被用于擦除铅笔痕迹。更好的是，在1858年，海门·李普曼发明了带橡皮的多功能铅笔。 1968年，美国一位科学家斯潘塞·西尔弗博士试图开发一种超强力的粘合剂。然而，他意外地创造了一种可重复使用的压敏胶。1974年，他的一个同事想到了用这种胶来固定书签。最初便利贴选中黄色也非常偶然，因为便利贴小组隔壁的实验室只有黄色小纸片可以用。 7 Read the text and fill in the form.
