4.Nowadays,people have many ways to read books.如今,人们有很多方式来读书。

4.1Nowadays

①用作副词,表示“现在”;“如今”,由于词义的原因,通常与一般现在时连用,且多用于句首或句末作状语。如:

Nowadays children are much healthier.现今孩子们比过去健康。

It's difficult to get into a university nowadays.如今进大学读书是难事。

从含义上看,该词往往具有与过去相比较的意味。

②有时放在名词后作定语。比较:

Nowadays children have more pocket money.如今,孩子们有更多的零用钱。

Children nowadays have more pocket money.现在的孩子有更多的零用钱。

③由于是作副词,而不是名词,所以不要在其前误加in,at等介词。

4.3“ No matter +疑问词”意为“无论……”、“不论……”,用来引导让步状语从句。

①no matter意为“不管;无论”,是从属连词。其后常接疑问词what,which,who,whom,where,whos e,when,how等,用来引导让步状语从句。从句既可放在主句之前,也可放在主句之后。no mater what"无论什么”;no matter which“无论哪一个”。what、which在从句中可作主语、宾语、表语或定语。

②no matter what/whose/which修饰名词时,该名词必须紧跟其后;no matter how修饰形容词或副词时,该形容词或副词也必须紧跟其后。

No matter how hard he works,he find it difficult to make ends meet.无论他多么努力工作,却总是入不敷出。

③词组no matter可独立成句,也可在句中担当成分。如:

No matter! 不要紧!

No matter,I'll go myself. 不碍事,我自个儿去。

词组no matter在it作形式主语、真正主语位于句末的句子中作表语。如:It is no matter that he didn't phone.他没打电话没关系。

no matter与疑问词who,what,where,when,how,if,whether等连用,意为“无论,不管”。

4.4keep on doing sth.“继续做某事,坚持做某事”,表示动作的反复,强调动作与动作之间有间隔。而keep doing sth.表示“一直做某事”,强调动作的连续性。

5.This is a modern printing press.

Which invention do you think is more important - the printing press or the Internet?你认为哪种发明更加重要?印刷机还是网络?

6.3the four great inventions of ancient China. 中国古代四大发明

6.4one of用法

①one of +代词宾格或名词复数

如:one of them

one of the students

②one of 短语做主语,谓语动词用单数

One of them is good at math.

④one of +the+形容词最高级+名词复数

one of the longest rivers

但是要注意下面的定语从句:

定语从句修饰the boys。

He is the only one of the boys who enjoys playing basketball.

one前面有定词the的时候,定语从句是修饰one的,所以动词要用单三形式。

6.5记住这四个词:paper,the compass,printing press and gunpowder.
