When we use metal, it is important to know how they react with different substances, for example, water and oxygen. 使用金属时，要了解金属和不同的物质怎样发生反应，例如水和氧气，这一点很重要。react 作不及物动词，“起化学反应”，react with sth. 与某物起化学反应它还有“对某人或某物做出反应”之意，常与介词to连用 react to sth./sb.2. The r

2、eaction of metals with these substances can be put in order.（不同的）金属与这些物质的反应程度可以按顺序排列起来。in order“按顺序、次序”，还有“适当的；能用的”意思，反义词组为out of order例如 He put his business affairs in order before he went to travel.翻译：The lift was out of order and he was trapped.翻译：3数字表达法（1）1,000以上词的表达法: 先从后向前数,每三位数加一个逗号，用这个方法把数目分

3、作若干段，再一段段的念；第一个逗号前的数为thousand, 第二million, 第三billion. 一般用作单数，若用复数形式，要用“复数形式of”。例如：4，007 four thousand and seven54,256,000 fifty-four million two hundred and fifty-six thousand14,800,000,000 hundreds of books 好几百本书thousands of young people （2）分数词构成法：分数词有基数词和序数词构成，基数词代表分子，序数词代表分母。分子是1时，分母用单数，分子不是1时，分母都

4、用复数形式。例如：1/2 one-second 1/4 one-fourth 3/4 three-fourths 2/3 two-thirds 5/9 five-ninths 1/2，1/4，3/4还可表示为 1又1/2 one and half 7又3/4 seven and three quarters3又2/5 three and two-fifths 47又3/8 4. The science facilities are very good，with laboratories that have all the latest equipment. 这些科研设施非常好,实验室配有最新的

5、设备。 （1）facility 常用作复数名词，表示为某种目的提供的设施（如房屋、设备、服务等）。例如：This is a 5-star hotel with good facilities.翻译： 也可用作单数，“设备；天赋；才能。”例：She has an amazing facility for maths.练习：We need to consider what we will be using for language training.A. abilities B. appliance C. facilities D. qualities （2）with在句中意为“带有，具有”，引导

6、短语对句子作附加说明，that have all the latest equipment 是定语从句，修饰先行词laboratories。例：He left for Beijing with a suitcase that contained a lot of money. 翻译： 5. The Nobel Prize is the highest scientific prize there is, so we should be very proud of that.诺贝尔奖是目前最高的科学奖，我们应该为此感到骄傲。be proud of 为而自豪 例如：We are proud of

7、our motherland.翻译： pride 是名词，词组有：have/take （a）pride in，be proud to do sth.例如：He took （a）great pride in being a student of Beijing University.I feel very proud to be a part of the team.二、语法要点 形容词和副词的比较级关于形容词和副词的比较级的用法，应注意以下具体问题：1. 表示比较的表达方式：（1） 表示倍数的三种结构： A: times as + 形容词原级 +as B: times the + 性质名词（s

8、ize, weight, height, length）+ of C: times + 形容词比较级 + than例如：This table is 3 times as big as that one. This table is 3 times the size of that one. This table is 3 times bigger than that one. (2) 同级的比较，用 asas, the same as, suchas构成：例如：She is as tall a girl as Ann. She is such a tall girl as Ann.The si

9、tuation is not so/as good as we hope. She got the same mark as John did.翻译以上各句。2. 比较级的特殊用法 （1） the + 比较级, the + 比较级 越 越.例如: The more you talked, the less attention he paid to you.你说的越多，他越不注意听你讲。The longer you stay, the better (it will be). 译: (2) 比较级 + and + 比较级 越来越例如: The new city is becoming more

10、and more beautiful. (3) the + 比较级 +of the two +名词 两者中较例如: The taller of the two boys is my brother. (4) 否定词+ 比较级 没有 比更例如: There is no greater love than that of a man who lays down his life for his friends. 为朋友而放弃生命的人的爱是最伟大的爱。He has never spent a more worrying day. 他度过了最担心的一天。 （5）no +比较级 + than 的特殊含义

11、no more than 两者都不 no lessthan 两者都很not morethan 不如 not lessthan 并不弱于3. 比较句型应注意以下几点：（1） 用介词by加数字与计量单位表示相差的程度。 例如：She is taller than I by three inches. 翻译： I missed the last train by one minutes. 翻译： （2）修饰比较级的常见修饰语有：rather, much, still, even, far, any（用于否定句或疑问句），a lot, a little, a great deal, by far, a

12、 bit, three times 等。例如：The students study even harder than before. 学生学习比以前努力得多。A car runs a great faster than a bike. 翻译： （3）比较的对象不能相互包容的有：any other + 单数名词，all (the) other +复数名词，比较级 +than +anyone else, any of the other +复数名词。例如：The Mississippi River is longer than any other river in the United State

13、s.密西西比河比美国任何其他一条河都长。China is larger than any other country in Asia. 中国比亚洲的任何其他国家都大。 （4）比较的对象应该相同。例如：The weather here is warmer than that of Shanghai.这里的天气比上海的暖和。（天气和天气相比）China has a larger population than any other county in the world.中国的人口比世界上任何其他国家的都多。（国家与国家相比较） （5）比较状语从句中代动词的使用。两个比较对象应在同一层面上比较，但从

14、句中除助动词、情态动词和系动词be外，其他动词不能重复使用，须用动词do 的适当形式代替。不同的人或物相比，时态应相同。例如：Bob looks younger than he is. 鲍勃看上去比实际年轻。I know you better than he does. 我比他更了解你。I know you better than him. 我了解你比了解他更清楚。 （6）比较结构中的省略现象，在日常交际中，彼此都明白，比较对象往往省略。例如：A: What do you think of the film? 你认为这部电影如何？B: I have never seen a better on

15、e. 我从来没看过比这部更好的了。（后边省略了than this film）Toms composition, if not better（后边省略了than Jacks ），is at least as good as Jacks. 汤姆的作文，如果不比杰克好的话，至少和他的一样好。4. 常用的比较级词组：no more than 只是；不多于not more than 至多no less than 至少；起码 not less than 不少于反馈检测I. 根据所给词首字母或汉语释义写出各单词的正确形式。 1.
