Step 1: Let the Ss read 1a again t find the new wrds and attributive clauses.
T: Nw, let’s read 1a again. Yu shuld circle the new wrds and underline the attributive clauses this time. When yu finish, put up yur hand.
T: There are five attributive clauses in this passage. See hw many yu have fund. Wh wants t have a try?
T: Marvelus! Yu have fund fur f them. Where is the last ne?
T: It’s here! Turn t page 102. Lk at the sentence “Besides, nt everything we read n the Internet is true r gd fr us”. In fact, there is a “that” after “everything”. In this clause, the relative prnun “that” acts as the bject f the verb “read”. In this case, the relative prnun is usually mitted.
Step 2: Let the Ss learn the new wrds by wrd frmatin r synnyms: in+side=inside, nrmal(adj.)+ly=nrmally(adv.), wrk+place=wrk-place, prper(adj.)+ly=prperly (adv.), tiny=very small, cnnect=jin… tgether, fr instance=fr example, besides=what’s mre=mrever =in additin.

Step 3: Let the Ss read 1a again and discuss in grups t find the difficult and key pints.
T: We have read the passage twice. Maybe sme f yu still have sme prblems. Nw, read 1a again and discuss in grups t find the difficult and key pints as well. When yu finish, put up yur hand.
T: First, let’s slve the difficult pints. Which grup first?
T: “There is n dubt that…”is a useful pattern. It means “It’s certain that…”. Wh can put it int Chinese?
T: Brilliant! That’s it.
T: Any ther questins?
T: They are nt exactly the same. Lk at the example “What ther sprts d yu like besides ftball?” and “I like all sprts except ftball”. The first example means “He likes ftball, t”, but the secnd example means “He desn’t like ftball at all.” Have yu gt it?
T: Yu are right.
T: There are many useful expressins in this passage. Grup 1, please speak ut what yu have fund.
Read 1a again t find the new wrds and attributive clauses.
S1: Fr example, tiny cmputers which are inside patients’ bdies can keep their hearts beating nrmally.
S2: In factries, rbts are cntrlled by cmputers that are like human brains.
S3: ..
S4: …
Ss: Srry, we dn’t knw.
Learn the new wrds by wrd frmatin r synnyms.
Read 1a again and discuss in grups t find the difficult and key pints.
S1: Hw t understand “There is n dubt that…in business?
S2: 毫无疑问……
S3: besides 是“除了”，except 也是“除了”，它们两个一样吗？
S4: 我的理解是“besides”是包括在内，“except”是不包括在内。
S5: in many areas f .., with the help f…, fr example, fr instance, …
S6: keep sth/sb. ding sth, place rders, cme int being,…
S7: thanks t, instead f ding sth., at wrk,…
对于文章末尾出现的新形式的定语从句，老师可以提一下。并指出关系代词“that”被省略了，因为它在从句中作宾语。
当学生找出新词后，老师要按照构词法、近义词或反义词来归类让学生学习。
对于本课内的词组辨析，不一定都要在本次课内解决，也可以放一点在讲解作业时处理。如：fr example和fr instance, besides 和except。
