4、-inRead 2d quickly and answer:When were the zipper invented?Who was it invented by?When were zippers popular?The zipper was invented in 1893.It was invented by Whitcomb Judson .Zippers were popular around 1917.The history of zippers拉鏈的出現(xiàn)是一個世紀(jì)之前的事。當(dāng)時(shí)，在歐洲中部的一些地方，人們企圖通過帶、鉤和環(huán)的辦法取代鈕扣和蝴蝶結(jié)，于是開始進(jìn)行研制拉鏈的試驗(yàn)。 1

5、893年，一個叫賈德森的美國工程師，研制了一個“滑動氏沒緊裝置”，并獲得了專利，這是拉鏈最初的雛形。這項(xiàng)裝置的出現(xiàn)，曾對在高統(tǒng)靴上使用的扣鈕扣鉤造成了影響。但這一發(fā)明并沒有很快流行起來，主要原因是這種早期的鎖緊裝置質(zhì)量不過關(guān)，容易在不恰當(dāng)?shù)臅r(shí)間和地點(diǎn)松開，使人難堪。 1913年，瑞典人桑巴克把金屬鎖齒附在一個靈活的軸上。其工作原理是：每一個齒都是一個小型的鉤，能與挨著而相對的另一條帶子上的一個小齒下面的孔眼匹配。 拉鏈最先用于軍裝。第一次世界大戰(zhàn)中，美國軍隊(duì)首次訂購了大批的拉鏈給士兵做服裝。但拉鏈在民間的推廣則比較晚，直到1930年才被婦女們接受，用來代替服裝的鈕扣。 拉鏈?zhǔn)窃?926年獲得現(xiàn)

6、在的名稱的。據(jù)報(bào)道，一位叫弗朗科的小說家，在推廣一種拉鏈樣品的一次工商界的午餐會上說：“一拉，它就開了！再一拉，它就關(guān)了！”十分簡明地說明了拉鏈的特點(diǎn)。拉鏈這個詞是這樣來的。2dRead the conversation quickly.Paul: Hey Roy, the subject for my school project is “Small inventions that changed the world.” Can you help me think of an invention?
