[Language Points] 1. I’m preparing some notes for a report called “Our growing population”. 我正在为一篇名为《我们不断增长的人口》的报告准备笔记。 prepare作及物动词时，意为“准备，使……准备好”等。作不及物动词时，意为“准备，预备”，后可接for sth或to do sth表示目的。如： When we arrived at home, Mum was preparing dinner for us. 我们到家时妈妈正为我们准备晚餐。 The teacher told his students to prepare for the exam. 老师让他的学生们为考试做准备。 2. And there was a lot of noise. noise为名词，意为“噪声；杂音”，指 刺耳、尖锐的声音。其形容词为noisy意为“喧闹的；嘈杂的”。 make noise意为“吵闹，制造噪音”。 I can’t stand that noise. 我受不了那种噪音。 It’s too noisy in the classroom. 教室里太吵了。 The children are making noise in the room all the time. 孩子们一直在房间里吵吵闹闹。 3. That causes a lot of problems, such as too much traffic and noise. 这引起了许多问题，如交通问题和噪音问题。 too much +不可数名词 too many + 可数名词 太多的… They bought too many eggs yesterday. 昨天他们买了太多鸡蛋。 She spent too much money on clothes. 她花太多钱买衣服。 cause为动词，意为“造成；引起”， 后可接名词或代词作宾语，也可接双宾语，即cause sb sth 或cause sth for sb；还可接动词不定式充当补足语的复合宾语，即 cause sb / sth to do sth。 What caused his elder brother’s illness? 他哥哥怎么病的？ You will cause trouble for your family. 你会给你的家庭带来麻烦的。 What caused you to change your mind? 是什么使你改变主意的？ 4. That’s almost one fifth of the world’s population. one fifth 意为“五分之一”，在英语中分数的表达为：分子使用基数词，分母使用序数词，当分子大于一时，分母使用复数形式。 “分数+of +名词”短语做主语时，谓语动词的单复数取决于of后面的名词的数。 Two thirds of the students have passed the exam.  三分之二的学生考试及格了。 Class is over!
