☆教材解读☆
1.With the Internet,we can learn about almost anything.?
◆with作介词,意思是“用……”,表示使用某种手段或者工具等。

她用小刀削铅笔。
【辨析】 with,in,by
(1)with通常指的是使用某种手段或者工具等。

(2)in 通常表示用某种语言、原材料或者方法去做某事。
Can you say it in English?
你能用英语说一下它吗?
(3)by通常表示通过某种方式或者手法来完成某事。
She goes to school by bike.她骑车去上学。
【拓展】 (1)with 可以表示“具有”,通常用来表示事物附带的属性。

我想买一个带花园的房子。
(2)with可以表示“和……一起”。
You can play with others.
你可以和其他人一起玩。
(3)with可以表示“与……有关”,涉及一件事对另一件事的牵连。
There is something wrong with my watch.
我的手表有一些毛病。
◆句中learn about 意思是“掌握,获得”,与learn of 意思相同。
You can learn about more knowledge from the Internet.你可以从网上学到更多知识。
【拓展】 (1)learn from从……学到。
She can learn from her classmates.
她可以向她的同学学习。
(2)learn by oneself自学。

她自学的汉语。
2.It has no keyboard or mouse,so it is easy to carry.?
句中or是连词,意思是“也不,没有”,常用于否定句中,引出两种或者多种事物,表示并列关系。常见用法:
(1)用于否定句中,表示“也不,没有”,和and意思相同,但是and只用于肯定句。
She doesn’t like basketball or baseball.
她不喜欢篮球,也不喜欢棒球。
(2)用于选择疑问句中,意思是“或者,还是”。常常构成句式:一般疑问句+or+其他?其回答不用Yes 或者No,而要用选择疑问句中提及的一项来回答。
—Does she like soccer or basketball?
她喜欢足球还是篮球?
—Basketball.篮球。
3.I use the Internet to blog about donuts.?
句中 blog作动词,意思是“写博客,写日志”。blog是不及物动词,后面一般接about,构成blog about sth 结构,表示“写关于……的博客或者网络日志”。blog的过去式和过去分词都是blogged,现在分词是blogging。
He sometimes blogs.有时他写写博客。
【拓展】 blog还可以作名词,意思是“博客,网络日志”,是一个可数名词。构成短语keep a blog,表示“写博客”。
She wants to learn how to keep a blog.

begin to do sth意思是“开始去做某事”,有时也可以用作begin doing sth。

【拓展】 有些情况只能用begin to do sth结构:
(1)用进行时态表示将来的时候。
She is beginning to swim.她将要开始游泳。
(2)当主语是事物的时候。
It began to snow yesterday.昨天开始下雪了。
(3)当begin 后面接带有感情或者心理活动的动词,如:understand,realize,know,think等的时候。
I began to understand what he said.
我开始理解他说的话了。
5.I will send my research to him by e-mail.?
句中send作动词,意思是“发送”,后面可以接双宾语,也就是send sb sth结构,表示“发送某物给某人”,相当于send sth to sb。
He can send you an e-mail tomorrow.
=He can send an e-mail to you tomorrow.
他可以明天给你发邮件。
【拓展】 (1)send还可以表示“送往,发射,派遣”,构成send sb to do sth 结构,表示“派某人去做某事”。
They sent him to learn new technology in America.他们派他去美国学习新技术。
(2)send sb to sp表示“送某人去某地”。
His father sometimes sends him to school.
有时他爸爸送他去上学。
[设计意图] 学生通过阅读课文,掌握重点内容,并且通过判断正误来巩固对课文的理解和懂的;朗读课文并填空,掌握课文重点句式。
StepⅥ.Complete Let’s Do It!
Ask the students to read the lesson again and answer the questions in No.1,then fill in the blanks in No.2,and pay attention to the new words and phrases.
[设计意图] Let’s Do It! 中No.1重点是阅读教学,回忆了课文的内容,使学生又一次巩固了文中知识,培养了阅读的能力。No.2强调的是文中的重点单词的用法,还有if引导的条件状语从句的用法。
StepⅦ.Task
GROUP WORK:Let’s Do It! No. 3
Ask students to come to the front of the classroom,and some start walking towards others as the teacher says “go”.They must stop as the teacher says “stop”.Then they can make a new group with the student who is standing in front of him/her.
[设计意图] No.3的重点是掌握网络的更多作用,同学们通过随机组合来完成小组合作。以“网络信息”为话题,提供了一个语境完整、内容丰富的对话,自然呈现本单元的核心句型,为学生进一步输出语言提供了口语示范。
StepⅧ.Exercises
