MP5 可以用来听音乐和看电影。 In many countries, English is used as the second language. 在许多国家，英语被用着第二语言。 I used to go shopping on Saturdays, but now I no longer do so. 过去我常常星期六去购物，但现在我不那样了。 The foreigners has been used to eating with chopsticks. 外国人已经习惯于用筷子吃东西。 We use the lift to go up and down. 我们用电梯来上下楼。 4. spread over意为“传遍；遍布在……；覆盖在……”。如 The news has spread over our school. 这个消息已经传遍了我们学校。 5.makes sb./sth.+形容词，意为“使某人/某物处于某种状态”，make是使役动词，该结构为“动词+宾语+宾补”，除了形容词外，动词原形也可以作宾补。如： The good news made him very happy. 这个好消息使得他很高兴。 What he said made me laugh for a few minutes. 他说的话让我笑了好几分钟。 6.be a danger to sb. / sth.意为“对某人/物有危害；对某人/物是一种威胁；有伤害”，相当于be dangerous to。与danger有关的常用搭配：be in danger处于危险中；out of danger脱离危险。如： Smoking is a serious danger to health. 吸烟对健康有严重的危害。 7. It’s no use doing sth. 是固定句式，意为“做某事是没有用的”，是固定句式，其中it是形式主语，真正的主语是后面的动名词短语。use用作名词时，意为“用途/处”。如： It’s no use crying. 哭是没有用的。 8. Though pollution is heavy now, I don’t think it’s hopeless. 尽管现在污染很严重，我认为还是有希望的。 本句为主从复合句，其中though引导让步状语从句，I don’t think是主句，it’s hopeless作think的宾语从句，省略了引导词that。 另外，I don’t think it’s hopeless是一种否定转移。这句话的双重否定，表示强烈的肯定语气。 hopeless是形容词，意为“没有希望的；无望的”，由“hope+后缀-less”构成。其反义词为hopeful，意为“抱有希望的”。-less是常见的形容词后缀，可加在一些名词之后，表示“无……，没有……”。常见的加后缀-less构成的形容词：careless粗心的；马虎的；useless无用的。如： It’s hopeless trying to convince her. 想说服她简直是徒劳。 9. 构词法：英语中的构词法主要有三种，即转化法、合成法和派生法。 1. 转化法 在英语中，一个单词由一种词性转化为另一种或几种词性而词形不变的方法叫做转化法。如： 1）动词转化为名词 Let me have a try. 2）. 名词转化为动词 Please water the small tree. 3）. 形容词转化为副词 How long have you lived there? 2. 合成法 由两个或两个以上的单词连在一起合成一个新词，这种构词法叫做合成法，合成的词叫做合成词。合成词一般看其词，知其意。如： sportsman，however 等。 3. 派生法 由一个词加上前缀或后缀构成一个与原单词意义相近或截然相反的新词叫做派生法。 1. 前缀 除少数前缀外，前缀一般改变单词的意义，但不改变单词的词性。 2.后缀 加后缀后词性容易发生变化。 常用前缀，后缀详见课本141页。 【习题巩固】 1.
