课堂学习
一.讨论课文内容并拓展运用它们
(1) The printing press let more people read more books.


1. let sb. to do sth. 意为“让某人做某事”。Let 后接动词原形、过去分词或副词等做宾语
补足语，但不可用现在分词。例如：
Let me help you .
The Internet lets people find and use information very quickly.
You’d better let the dog out but not let the cold air in.
2. let 的反义疑问句的变化。 Let ‘s do… 后面附加疑问句用shall we?; 而 let us/sb do…
则用will you .例如：
Let’s enter the park to have a look ,shall we?
Let us /him go into the computer center, will you ?
(2) The printing press is a machine that can make lots of books in a short time.
…that can make lots of books in a short time 是定语从句，关系代词that 代替先行词
machine 在定语从句中作主语，所以不能省去。例如：
This is the man who stole my necklace.
The woman likes things that are cheap.
(3) Before the printing press ,books were written by hand .
by hand 意为“靠手，用手”，by 在此意为“通过……的方式”，后常接名词、代词或
动名词做介词的宾语。例如：
My room is heated by electricity .
He is talking to Kate by telephone.
He makes a living by teaching .
(4) Information began to travel much faster and much farther.
1. begin to do sth. 意为“开始做某事”。begin 可以用不定式做宾语，也可用v.-ing 作宾
语。例如：
They began to read the text.
When did you began to learn /learning English?
2. begin 是瞬间动词，不能与表示一段时间的状语连用。例如：
The meeting has been on for half an hour.
上句不可以写为The meeting had begun for half an hour.
但可以写为 The meeting began half an hour ago.
3. much faster and much farther 意为“快的多，远的多”much 修饰比较级，表示“……
得多”。可修饰比较级的词还有 a little ,even ,far ,a bit ,a lot 等。so ,too, very ,quite 不能修饰
比较级，后面接原级。例如：
You can get much more than you want .
The gun sounded even closer.
(5) If you forgot something ,you could look it up.
look up 意为“（在词典中或参考书中）查找（词或资料）”.look up 如果接代词宾格时，
此代词应放于look 与 up 之间。
Please look them up in the dictionary .
I want to look up his telephone number.

二. 根据汉语，补全句子
1. 这台机器在短时间内能制出许多书。
The machine can make ____ ____ books ____ _____ _____ _____.
2. 你最喜欢哪本书？A ,B 还是C?
