14、ed in electrical equipment. 句式分析在该句中for example为插入语，后面接的是由并列连词and连接的两个简单句，其中两个简单句中“主语is used .”是被动语态。尝试翻译不同的金属有不同的用途，比如，钢材被用于汽车中，铁被用于电器设备中。2When we use metals, it is important to know how they react with different substances, for example, water and oxygen.句式分析When we use metals是时间状语从句，it为形式主语，真正的主语是

15、后边的动词不定式to know how .。尝试翻译当我们使用金属时，了解它们与不同的物质如何反应很重要，比如，水和氧气。3Here is a table with the metals that react most at the top, and the metals that react least at the bottom.句式分析此句为倒装句。here置于句首，主语为名词，此时要将谓语动词放在主语前构成倒装。两个that从句都是定语从句，修饰前面的先行词metals。at the top和at the bottom在句中作宾补。尝试翻译这里有一个表格， 反应最强的金属在上面， 反应

17、ew substance is formed. A change is not a chemical change if it doesnt form a new substance.Physical changes are very common, too. There are many examples. You can make a physical change by tearing a piece of paper into two, or by cutting a piece of iron with lathe (机床). Here paper is still paper, a

18、nd the iron is still iron.Another way of making physical change is dissolving something in water. When you dissolve salt in water, the salt disappears. You may think that a new substance has been formed. But really there is no new substance. The salt is still salt. You can still taste it. So the dis

19、solving of anything is a physical change.When water freezes, the change is also a physical one. The water changes from liquid to solid, but it is still the same substance. That is why the freezing of anything is a physical change.语篇解读：本文主要讲了两种变化化学变化和物理变化。1The dissolving of salt in water is _Aa physi

20、cal changeBa chemical changeChydrogen and oxygenDbreaking up解析：选A细节理解题。根据文章第四段，尤其是最后一句可知：溶解任何东西都是物理变化。2The change of the three states of water is _Aa chemical changeBdifferent substancesCa physical changeDthe same state解析：选C细节理解题。从文章最后一段得知水从液体变为固体或变为气体，并没有生成一种新的物质，仍是同一种物质，因此水的三种形态变化属于物理变化。3We can se

21、parate a chemical change from a physical one by _Athe change of shapeBthe change of colorCnewlyproduced smokeDnewlyformed substances解析：选D推理判断题。由第二段可知在化学变化中有新物质产生，只要没有新物质产生就不是化学变化。由此得知：判断是化学变化还是物理变化的依据是看是否有新物质产生。4If you change water into hydrogen, it is _Aa physical changeBa chemical changeCa physica

22、l and chemical changeDnot a change解析：选B细节理解题。根据第二段可知：把水分解成氢气和氧气，是一个化学变化。BThere are many interesting science experiments out there for young kids. You can wow your friends and teachers with them.

23、eresting science experiment. One such experiment is to show your friends and teachers that you can make mothballs (樟脑丸) dance !

25、fairly rough, they should begin to bounce up and down in the glass. You can also do a similar experiment with raisins (葡萄干) and clear pop,_such as Sprite.

26、own in the glass of Sprite. You can also replace the raisins with mothballs and you should get the same effect in the Sprite. This project works because the irregular surfaces of the mothballs and the raisins hold some CO2 bubbles (气泡), causing them to bounce up and down in a dancing motion.语篇解读：文章向

29、s are needed in the experiment?abaking soda bwatercmothballsdsalt evinegar fsugarAbcef BacdeCabcd Dabce解析：选D细节理解题。根据第三段的“a glass filled half full with water. Add a little bit of vinegar (醋) to your glass of water, about 1/3 or 1/4 of a cup (60 ml), and one teaspoon (10 ml) of baking soda”可知应选D。8The

30、underlined word “pop” in Paragraph 4 probably refers to “ _”Aa mothball Ba kind of vinegarCa drink with bubbles Da special kind of raisin解析：选C词义猜测题。根据画线词后“such as Sprite”以及“hold some CO2 bubbles”可知pop在这里是指含有二氧化碳的饮料。CMonthly Talks at London Canal MuseumOur monthly talks start at 19：30 on the first Th
