Step IV Language points
1. we waited for weeks to hear from our pen friends abroad.收到国外笔友的来信需要好几周的时间。
hear from 收到…的来信；从…听到
I shall defer replying till you hear from home.我将收到家信以后再给你回复。
I never saw him again, nor did I hear from him.我再也没有见过他，也没有收到过他的信。
2. Some were huge ones with thousands of pages.我们从大量的书籍中成千上万页中获取信息。
thousands of成千上万的
He donated thousands of pounds to charity. 他向慈善事业数千英镑。
拓展：
hundred，thousand 及 million的具体用法
1) 用单数的场合
当这些词与具体数字连用时, 习惯上用单数，而且其后也不接介词of 。
He was prepared to pay two million.他愿意支付200万。
More than a hundred people were injured.有一百多人受了伤 。
但是，当这些词后面的名词有了the，these, those等特指限定词修饰时，或其后接的是us, them这样的人称代词时，此时必须用介词of。
About three hundred of them have left there.他们当中约有300人离开了那儿。
2) 用复数的场合
当这些词不与具体数字连用，而是表示不确定的泛指概数时，则不仅要用复数，而且要 接介词of, 然后才能接名词。
The sun was shining. Thousands of people were lying on the beach.阳光灿烂，数以千计的人躺在海滩上。
A careless mistake cost the company millions of pounds. 一个粗心的错误使公司蒙受数百万镑的损失。
3. OK. That can be fixed. 好的，我来修理它。
fix 修补，修理。
My watch has stopped. It needs fixing.我的表停了，需要修理 了。
辨析：repair, mend与fix
这三个动词都可以用来表示“修理”某一事物，使其能恢复到原来的形状或形态的意思。
1) repair的对象范围很广，从房屋、道路、机器到日常生活必需品，是使受到一定损失或失灵的东西恢复其形状或功能。
Who has repaired the broken leg of the table? 谁把桌子的断腿修好了？
2) fix用于需要重新“调整”物体的结构，把松散的部件固定结实，将分离的物体各部分装配起来。在美国口语中，它与repair无太大区别。
Can you fix the broken chair?你能修理那把坏了的椅子吗？
fix指“修理”时，是个非正式的用语，它的基本含义是将某物“固定”在某一地方。 fix可用来指“修补”或“整理”任何出了毛病的东西，使用范围较repair广。
I am going to fix my bicycle tomorrow.我准备明天修理自付车。
4. I’ve got an empty memory card. 我有一个空储存卡。
1) 现在结构have got在口语中相当于一般现在时have的意义，表示“有”。不过，在美国英语中常用have,而在英国英语中则常用have got。
He has got a brother. = He has a brother.他有 一个兄弟。
2) 这两种表达结构在问句方式上略有不同，现在完成时结构只有一种疑问方式.
即： Have / Has…got…？而一般现在时结构有两种疑问方式，即：Do/Does... have...?或 Have / Has...?
你有一把雨伞吗？
Have you got an umbrella?
Do you have an umbrella?
Have you an umbrella?
这两种结构疑问句的冋答略有不同。
—Have you got a dictionary?
—Yes, I have. / No, I haven’t.
—Do you have a dictionary?
—Yes. I do. / No, I don t.
