1、Passage AIt is hard to think of a world without metals have different uses，for example，steel is used in cars，and iron is used in electrical we use metals，it is important to know how they react with different substances，for example，water and reaction of metals with these substances can be put in is a

4、ter.Apparatus: 3 clean iron nails；test tubes；test tube holder；cotton wool；oil；Bunsen burner.Iron in dry airMethod(1) Put some iron nails at the bottom of a test tube.(2) Push some cotton wool down the tube.(3) Leave the tube for one week.ResultAfter one week，the nails have not rusted.ConclusionIron

5、does not rust in dry air.Iron in airfree waterMethod(1) Halffill a test tube with water.(2) Boil the water for three minutes.(This makes sure there is no air in the water.)(3) Put two or three clean nails in the water.(4) Add some oil to the will keep air out of the water.(5) Leave the tube for one

6、week.ResultThe nails do not rust in the tube with airfree water.ConclusionIron does not rust in airfree water.Iron in ordinary waterMethod(1) Halffill a test tube with water and add two or three clean nails.(2) Leave the tube for one week.ResultThe nails rust in the tube with ordinary water.Conclusi

7、onIron rusts in ordinary water.文章A很難想象一個(gè)沒有金屬的世界。不同的金屬有不同的用途，比如，鋼材用于汽車中，鐵用于電氣設(shè)備(electrical equipment)中。當(dāng)我們使用金屬時(shí)，了解它們與不同的物質(zhì)如何反應(yīng)(react)很重要，比如，水和氧氣。(不同的)金屬與這些物質(zhì)的反應(yīng)(reaction)程度可以按順序排列。表中金屬反應(yīng)最強(qiáng)的排在上面，反應(yīng)最弱的排在下面。 金屬在氧氣中加熱跟水或蒸汽反應(yīng)鉀(potassium)燃燒生成(form) 氧化物(oxide)跟冷水反應(yīng)鈉 (sodium)鈣 (calcium)鎂 (magnesium)跟蒸汽反應(yīng)鋁 (a

9、沒有空氣的水中方法(1)在試管中注入一半水。(2)把水煮 (boil) 3分鐘。(這樣可以確保水中沒有空氣。)(3)把2到3枚干凈的鐵釘放入水中。(4)在水中加入(add.to.) 一些油。這將防止空氣進(jìn)入水中。(5)將試管放置一周。結(jié)果鐵釘在沒有空氣的水中沒有生銹。結(jié)論鐵在沒有空氣的水中不生銹。鐵在普通的水中方法(1)在試管中注入一半水，加入2到3枚干凈的鐵釘。(2)將試管放置一周。結(jié)果鐵釘在盛有普通的水的試管中生銹了。結(jié)論鐵在普通的水中生銹。My feelings about science have really never used to enjoy science，but last

10、year I changed schools，and the science teachers at my new school are science facilities are very good，with laboratories that have all the latest chemistry teacher，Mr Longford，takes us to public science lectures about four times a term，and these are always very interesting，as the lecturers are people

11、 who have made real discoveries in their area of fact is，Canada has many firstclass the last twenty years，seven Canadian scientists have won the Nobel Prize！The Nobel Prize is the highest scientific prize there is，so we should be very proud of that.Im becoming more and more interested in physics，and

12、 have decided that I want to study it at m going to try to go to either Montreal or Ottawa University，as both are supposed to have good Physics parents are always thought I would become an English teacher！我對理科的感受真的改變了。過去(used to)我從不喜歡理科，但是去年我轉(zhuǎn)學(xué)了，我的新學(xué)校的理科老師很棒?？蒲性O(shè)備(facility)很好，有配備了最新設(shè)備的實(shí)驗(yàn)室。我們的化學(xué)老師朗福德先生大約每學(xué)期帶我們?nèi)ヂ犓拇喂部茖W(xué)講座(lecture)，這些講座總是非常有趣，因?yàn)檠葜v者都是一些在各自的科學(xué)領(lǐng)域(in the area of)真正有所發(fā)現(xiàn)的人。事實(shí)是，加拿大有很多一流
