探究新知
1a Read the statements below.
“A”（for agree）or“D”（for disagree）.读下面这些叙述，同意的圈上A，不同意的圈上B。
知识点1 I think teenagers should be allowed to go out with their friends every night
我认为应该允许青少年每天晚上和朋友出去。
【讲解】allow动词，“允许，准许”之意。allow sb.to do sth.“允许某人做某事”是主动语态。
be allowed to do sth.“被允许做某事”，是被动语态。
should be allowed to do sth.表示“应当被允许做某事”。如：
Smoking is not allowed here.此地禁止吸烟。
My parents won’t allow me to stay out late.我的父母不允许我深夜不回家。
You should allow your son to spend time with his friends on weekends.你应该准许你的儿子周末时同他的朋友们在一起。
We should be allowed to sing popular songs in school.学校应该允许我们唱流行歌曲。
Teenagers should not be allowed to drive.不应允许青少年驾车。
【例1】同义句转换。
①They allow us to have part—time jobs.
We ________ ________ to have part—time jobs.
②We should allow children to spend time with their friends.
Children______ ______ ______to spend time with their friends.
【解答】①are allowed②should be allowed
提示
“be＋动词过去分词”是被动语态的基本结构。如：be allowed 被允许。
知识点2 I don’t think twelve—year—olds should be allowed to get their ears pierced.
我认为不应该允许十二的孩子将耳朵穿孔。
【讲解】（1）twelve—year—old复合形容词，“十二岁的”。其中year不能用复数形式。
twelve—year—olds表示“十二岁的孩子”
（2）get their ears pierced“将他们的耳朵穿孔”，pierced是过去分词。如：
A five—year—old boy was lost.一位五岁的男孩走失了。
Eighteen—year—olds are allowed to have jobs.准许十八岁的青年从事工作。
When are you going to get your hair cut? 你打算什么时候去剪头发？
【例2】单项选择
① My new friend is a______boy.
A．sixteen—years—old
B．sixteen—years—olds
C．sixteen—year—old
D．sixteen—year—olds
②My dad took me to______ in the hospital.
A．get my eyes examine
B．get my eyes examined
C．get my eyes to examine
D．get my eyes examing
警示
get sth.done 使某事……，请人做某事
get sb. to do sth.让某人做某事
【解答】①boy前应是作定语的修饰词，因此用复合形容词，答案C正确。②题意表示“请医生检查我的眼睛”可使用get sth.done，故B正确。
拓展归纳：
含有数字和名词构成的复合词中，名词用单数。如：
400—metre四百米的
800—word八百字的
ten—year—old十岁的
fifty—metre—long五十米长的
1b Listen and “T”（for true）or“F”（for false）.听录音，并将对的圈出“T”，错的圈出“F”。
听力材料：
Woman:So, what are you doing this afternoon, Anna?
Girl:I’m going to the mall with John. He just got his driver’s license.
Woman:I’m sorry. You can’t go with John. I don’t think sixteen—year—olds should be allowed to drive. They aren’t serious enough at that age.
Girl: But I have to go to the mall. Gaby’s getting her ears pierced and I want to watch.
Woman:I don’t think sixteen—year—olds should be allowed to get their ears pierced. They might be sorry later.
Girl :I agree, but it’s fun to watch. Is it OK if we take the bus?Woman:Well, I guess so.
Girl: Great! I want to buy a new blouse at the mall, too.Woman: What kind are you going to buy? Maybe I should go with you.
Girl: Aw, Mom. I’m not a child. I think teenagers should be allowed to choose their own clothes.
Woman: Well, I just want to be sure you get something nice.

Kathy: You know what worries me—Larry doesn’t seem to have many friends.
Molly: Really? I didn’t know that.
Kathy: Yes, Molly. He needs to spend time with friends.
Molly: Like you and me?
Kathy: Maybe.
参考答案

Molly 1．Disagrees 2．Agrees 3．Doesn’t know 4．Disagrees 5．doesn’t know
知识点4 He should stop wearing that silly earring.他应该停止戴那只可笑的耳环。
【讲解】stop doing sth.“停止做某事”，表示将所做的事停下来。
stop to do sth.“停下来去做某事”表示停止原来做的事，而开始做另一件事。
The girl soon stopped crying.那女孩很快就停止了哭泣。
It stopped raining.雨停了。

C．stop to have
D．stop having
②When Miss Green began to ______ something, the two boys stopped ______ and became quiet.
A．speak; telling
B．talk; speaking
C．say; talking
D．tell; saying
【解答】①根据题意，建议对方休息，应为stop to have a rest，并且why not后接动词原形，因此C项正确。②从句表示“开始说事情”，用动词say；主句表示“停止交谈，不说话”，应为stop talking。故正确答案是C项。
2b Listen again.What are Kathy’s and Molly’s reasons? Number their reasons in the correct order.重新听录音，凯西和莫利的理由是什么？请将她们的理由按正确顺序排列。
参考答案:
4 1 5 2 3

【讲解】need此处是实义动词，有人称、数和时态的变化，后面可接名词、代词、动词不定式作宾语。如：
Our school needs English teachers.我们学校需要英语老师。
You need to take some food.你需要带上一些食物。
【例5】用所给动词正确形式填空。
①You needn’t _______（finish） the work today.
② He needs ________ （finish） the work today.
【解答】①need此处是情态动词，后面跟动词原形finish。②needs此处是实义动词，后接不定式to finish。
警示
sb.need to do sth.某人需要做某事
sth.need doing 某事需要做
拓展归纳:
need作情态动词时，无人称、数和时态的变化，后接动词原形，多用于疑问句和否定句。must开头的疑问句否定回答可用needn’t，表示“不必，没必要”，相当于don’t have to。如：
Need I wait here? 我需要在这里等着吗？
You needn’t tell him about it.你不必把那件事告诉他。
—Must I pay for it? 我必须为此付款吗？
—No，you needn’t.不，没有必要。
2c PAIRWORK

3a Read the conversation.Then write Sun Fei’s and Wu Yu’s rules in the chart.Use “Don’t”and“You can”.读对话，然后把孙菲和吴玉的准则填写在表格里，使用“Don’t”和“You can”。
参考答案:
Sun Fei: You can go to the movies with friends on Friday nights, but you have to be home by 10:00 pm.
Wu Yu:You can go to the movies with friends on Friday nights. You can go shopping with friends on Saturday afternoon. You can choose your own clothes. Don’t get your ears pierced.
知识点6
—We have a lot of rules at my house.在我的家里有很多的规矩。
—So do we.我的家也是如此。
【讲解】so置于句首，表示“另外的人或事也是如此”时，需要用倒装句，即为“So＋助动词/连系动词/情态动词十主语”。其中助动词，连系动词，情态动词在时态上与上文一致，在人称和数方面与倒装句中的主语一致。如：
【例6】单项选择
①They went there by bus, so______I.
A．do
B．does
C．did
D．am
②—I have seen the film on TV. What about you? —_____.
A．So did I
B．So I did
C．So I did
D．So have I
【解答】这两题均是承上文表示另一个人也是如此，需要用倒装句，因此①答案是C，②答案是D。
拓展归纳:
So do I属于倒装句，意思是承上文的肯定陈述表示“我也一样”。
So I do表示说话人对前面或对方所说情况的赞同或证实，意思是“我确实如此”。
