　　step3、精读足练
　　1、语言点导学
　　学生自读课文，找出疑难问题，先小组后全班解决。
　　1)every evening my mother looks through magazines at home.每天傍晚，我妈妈在家翻阅杂志。 look through是一个动词短语，表示＂浏览，粗略地翻阅＂。如：i haven’t looked through the book yet.我还没有翻完这本书。would you quickly look through the composition for me and see if there are any mistakes?你能不能帮我快速看一下这篇作文，看看有没有错误？
　　2）but in those days, books could only be produced one at a time by hand..但在那个年代，依靠手工，一次只能制作一本书。
　　at a time表示＂每次，一次＂。如：please come in one at a time,not all together.请一个一个地进来，不要一起来。i’m sorry but i’m too busy to help you now__i can only do one thing at a time.真抱歉，我现在太忙了，无法帮你——我一次只能干一件事情。
　　by hand可以表示＂手工地，亲手地＂。如：
　　all these toys are made by hand, not on a machine.所有这些玩具都是手工制作的，不是机器生产的。you’d better deliver her invitation by hand since she lives so close.既然她住得这么近，你最好亲自将邀请信送给她。
　　3）today information can be received online, downloaded from the internet rather than found in books…如今，信息可以在线接收、从因特网下载，而不必到书中寻找…
　　rather than表示＂而不是，胜于＂。如：i want to wear the black shoes rather than the brown ones.我想穿那双黑色的鞋，而不想穿褐色的。 everybody likes to go to the park rather than stay at home.大家都想去公园，而不愿呆在家里。

　　2)were books produced by hand or by machine at first? what was the paper held against?
　　3)when was printing developed? why did ideas spread more quickly when books became cheaper?
