7. key n. 钥匙
eg. He put the key in the lock and turned it. 他把钥匙插入锁里，然后转动钥匙。

【拓展】key是一个多义词，作名词时还有如下含义：

(2)答案：Do you know the key to the problem? 你知道这道题的答案吗？

二、重要短语
1. quite a few相当多；不少
I have been in Shanghai for quite a few years. 我在上海已经待了很多年了。

quite a few是“相当多，不少”，与many意思相近，用于修饰可数名词的复数形式。

Quite a few people came to the lecture. 有相当多的人来听演讲。

He has quite a few friends. 他有不少朋友。

修饰不可数名词时，应用quite a little(相当多；不少)。

eg. There is quite a little rice left in the bag. 米袋里还剩下不少大米。

quite a little与much意思相近。

2. in charge of负责掌管
eg. The chief engineer was in charge of directing the building of the underground.总工程师负责指挥地铁的建造。

I am in charge of my sister. 我在照看妹妹。

【拓展】
in charge of 意为“负责掌管”，
=take charge of负责；照管；监理；担任
= be responsible for 负责
eg. He took charge of the farm after his father’s death. 父亲去世后，他接管了农场。

3. have a good time过得愉快
have a good time与enjoy oneself(greatly)“过得愉快，玩得高兴”意思相近。

eg. Did you have a good time at the party last night?昨晚的聚会你玩得开心吗？
=Did you enjoy yourself at the party last night?
批注：也常用have a great/nice time等表示“玩得很高兴，过得很愉快”的意思。

二、重要句型
1. Kitty's cousins, Lucy and Simon, have come to Garden City to visit the Li family.
基蒂的堂妹露西和堂弟西蒙到花园城市去拜访李先生一家人。

在这个句子中，现在完成时用于表示动作已经发生（但并不追究动作发生的具体时间），并对现在产生一定的影响（即目前露西和西蒙已经在Garden City了）。

eg. I’ve lost my passport. 我把护照丢了。

（其含义是：I can't find my passport now.）
-Where's Linda?琳达在哪儿呢？
-She’s gone to bed. 她去睡觉了。

（其含义是：She is in bed now.）
We've bought a new car. 我们买了一辆新车。

（其含义是：We have a new car and can use it now.）
2. How long has she been a teacher?她当老师多久了？
eg. She has been a teacher since 1997. 她从1997年开始当老师的。

上述两个句子也使用了现在完成时。

本例中的现在完成时用于表示某个动作发生的起点在过去，这个动作一直持续到现在，并还有可能持续下去。

这样的句子通常会加上for或since引导的时间状语。

如：
eg. He has been a teacher here since 1981. 他自1981年起就在这儿当老师了。

（可能还要继续在这儿教很多年）
I have't seen her for four years. 我有四年没见到她了。

【友情提示】如果句子中的谓语表示持续的动作含义，现在完成时结构中的动词需使用持续性动词，而不可使用短暂性动词。

试比较：
【正】I have been in the club for three years. 我加入这个俱乐部已经有三年了。

【误】I have joined the club for three years. (join是短暂性动词)
for和since是现在完成时中常见的两个引导时间状语的词。

表示时间的for不能用于以all开头的短语前。

They've worked all day. 他们已干了整整一天。

总之，我们应当记住：for+时间段，since+时间点。

批注：有关于现在完成时的用法可以在C专题部分给学生详细拓展讲解，包括其结构，标志词，常见短暂性动词变为延续性动词用法。

3. He catches thieves and helps keep the city safe. 他抓捕小偷、保卫城市的安全。

"keep+名词+形容词”的结构常用来表示‘使……保持某种状态”的意思。

eg. We should try to keep the environment clean. 我们应当尽力保持环境卫生。

Would you please keep your room tidy, Ben?本，你能不能让自己的房间保持整洁？
【拓展】
keep doing sth.一直做某事
keep fit =keep healthy 保持健康
keep ….from 阻止;使......免于
keep in touch (with)sb. 与某人保持联系
keep off 阻挡；不让......接近
keep sb busy 是某人忙个不停
批注：拓展部分是考纲中要求需要掌握的有关keep 的用法，对于成绩较好的学生可以引导学生学生记忆并给与一定的强化练习。

4. Aunt Betty works in a company in Beijing, doesn't she?贝蒂婶婶在北京的一家公司工作，不是吗？
这是一个反意疑问句。

反意疑问句是英语四大问句之一，它是由一个陈述句加上一个短问句构成。

反意疑问句的基本构成形式是：陈述句+逗号+助动词/be动词/情态动词（肯定或否定形式）+主语。

eg. She often has lunch at school, doesn't she?她经常在学校吃午饭，不是吗？
You don't like sports, do you?你不喜欢体育运动，是吗？
批注：讲解反义疑问句时可以让学生记住简单的口诀：前肯后否，前否后肯。

另外常用的否定词如：little,few,neve等可以用口诀让学生记住：上海男人疯了(SHNRFL)-- seldom, hardly,never, rarely, few,little.
5. A watch is used for telling the time. 手表是用来报时的。

eg.We use a watch for telling the time. 我们用手表来报时。

①
A watch is used for telling the time. 手表是用来报时的。

②
(1)我们把句子①的结构称为“主动语态”，把句子②的结构称为“被动语态”。

主动语态句的主语是动作的执行者，而被动语态句的主语是动作的承受者。

被动语态的基本结构是“be+动词的过去分词”。

be used for的结构表达“被用来……”的意思，后接动词的-ing形式。

eg.Chopsticks are used for eating food. 筷子是用来吃饭的。

A knife is used for cutting things. 刀是用来切东西的。

The building was used as a shelter for homeless people.那座楼房用来收容无家可归的人。

(2) tell the time意为“报时”。

eg.Little Mary can now tell the time. 小玛丽现在会认时间了。

【拓展】
used to do 过去常常做某事
be used to doing习惯于做某事
be used by被……使用
be used as被……用作
批注：拓展部分是中考中常考的辨析题，对于基础较好的学生可以详细讲解一下。

讲解方法：如，used to do 过去常常（used是过去时），be used to doing sth.习惯于做某事(be doing 表一直在做的事情)
6. A key ring is used for holding the keys. 钥匙圈是用来挂钥匙的。

hold有“拿着；抓住；夹着”的意思。

hold在句中作及物动词时，有以下意义和用法：
(1) 握；抓住；拿住。

如：She is holding up an umbrella. 她正打着伞。

He held me by the sleeve. 他抓着我的袖子。

Hold the line. （打电话用语）稍等／别挂断。

(2)容纳；装着。

eg. The hall can hold 1,000 people. 这个大厅能容纳1000人。

(3)拥有；占有。

eg.I held the job for two years. 这工作我干了两年。

(4)举行（会议等）。

eg.The Olympic Games are held every four years. 奥运会每四年举办一次。

【拓展】hold back意为“阻碍，阻止”。

hold on意为“等待，不要挂断电话”等。

hold up意为“举起；抬起，耽搁”。

7. Yesterday, we took the cable car to the top of a hill. 昨天，我们乘缆车去了山顶。

the top of意为“……的顶部”，常用于at the top of(在……的顶部)等短语中。

eg.We can have a nice view from the top of the mountain. 从山顶上往下看，我们可以欣赏到不错的景色。

She is screaming at the top of her voice. 她正在声嘶力竭地尖叫。

给学生1-2分钟时间回顾一下上面讲到的词汇，并让学生讲解存在疑惑的词汇和教材中其他词汇。
