Passage A （A篇）It is hard to think of a world without metals. 很難想象一個沒有金屬的世界。譬如，鋼用于車輛，鐵用于電器。The reaction of metals with these substances can be put in order. （不同的）金屬與這些物質(zhì)的反應(yīng)可以按順序排列起來。Metal金屬Heated in oxygen在有氧狀態(tài)下加熱Reaction with water or steam與水或水蒸氣的反應(yīng)Potassium鉀Burns to form an oxide燃燒后生成氧化物Reacting with cold與冷水反應(yīng)Sodium鈉Calcium鈣Magnesium鎂Reacting with steam與水蒸汽反應(yīng)Aluminium鋁Zinc鋅Iron鐵Reacts slowly反應(yīng)緩慢Partial reaction部分反應(yīng)Copper銅Partial reaction部分反應(yīng)No reaction不反應(yīng)Passage B （B篇）A Simple Scientific Experiment一個簡單的科學(xué)實(shí)驗(yàn)Below is a description of a simple scientific experiment. 下文是對一個簡單科學(xué)實(shí)驗(yàn)的描述。Aim：to find out if iron rusts a) in dry air。 c) in ordinary water. 目標(biāo)：發(fā)現(xiàn)鐵是否在下列狀態(tài)下生銹：a）在干燥的空氣中；b）在不含空氣的水中（無空氣水）c）在普通水中。 test tubes。 cotton wool。 Bunsen burner. 儀器：三支潔凈的鐵釘、試管、試管夾、棉花、油、本生燈（即煤氣燈）Iron in dry air鐵在干燥的空氣中Method方法： some iron nails at the bottom of a test tube.； some cotton wool down the tube.； the tube for one week.。Conclusion結(jié)論：Iron does not rust in dry air. 鐵在干燥的空氣中不生銹Iron in airfree water鐵在不含空氣的水中Method方法： a test tube with ； the water for three minutes.(this makes sure there is no air in the water)（這可以保證水中無空氣）； two or three clean nails in the water. —3枚潔凈的鐵釘； some oil to the water. This will Keep air out of the water.。Result結(jié)果：The nails do not rust in the tube with airfree water. 鐵釘在無空氣水的試管中未見生銹。Iron in ordinary water鐵在普通水中Method方法： a test tube with water and add two or three clean nails，并在水管中放2—3枚潔凈的鐵釘； the for one 。Conclusion結(jié)論：Iron rusts in ordinary water鐵在普通的水中會生銹。s accessible through a puter. 因特網(wǎng)是世界上最大的信息源，借助電腦便能進(jìn)入。In 1969, DARPA, a US defence organization, developed a way for all their puters to talk to each other through the telephone. 1969年，一個名叫DARPA的美國國防組織，研發(fā)出一種使他們所有的電腦通過電話交談的方法。For fifteen years, only the US army could use this system of munication. 在15年的時間里，只有美國軍方才能使用這一交流系統(tǒng)。It then became possible for universities to use the system as well. 各大學(xué)也能使用這一系統(tǒng)。The World Wide Web (the web)is a puter network that allows puter users to access information from millions of websites via the Internet. 萬維網(wǎng)是一種能夠使電腦用戶通過因特網(wǎng)從眾多網(wǎng)站獲取信息的電腦網(wǎng)絡(luò)。 By 2020, much web traffic could be in Chinese. 到2020年時，大量的網(wǎng)絡(luò)交流有可能使用漢語普通話。李于I99i年創(chuàng)建。李利用一臺舊電視制成了他的第一臺電腦! He came up with the idea of the World Wide Web in 1989 while he was working in Switzerland. 1989年，當(dāng)他在瑞士工作時，他提出了(創(chuàng)建) 萬維網(wǎng)的想法。李使任何人，而不僅僅是大學(xué)和軍隊(duì)，使用因特網(wǎng)成為了可能。 From that moment on, the web and the Internet grew. 從那時起，萬維網(wǎng)和因特網(wǎng)蓬勃發(fā)展了。The Internet has created thousands of millionaires, but BernersLee is not one of them. 因特網(wǎng)造就了成千上萬的百萬富翁，但不包括貝爾納斯 Everyone in the world can access the Internet using his World Wide Web system. 任何人部可以利用萬維網(wǎng)系統(tǒng)進(jìn)人因特網(wǎng)。李現(xiàn)任美國波士頓麻省理工學(xué)院講師。2. 若不是心寬似海，哪有人生風(fēng)平浪靜。用一些事情，總會看清一些人。既糾結(jié)了自己，又打擾了別人。4. 歲月是無情的，假如你丟給它的是一片空白，它還給你的也是一片空白。你必須努力，當(dāng)有一天驀然回首時，你的回憶里才會多一些色彩斑斕，少一些蒼白無力。
