2、I think two hours of TV is enough for you!我觉得你看两个小时的电视已经足够了。
1）、two hours of TV 表示时间、距离、金额、度量等词语作主语时,通常被视作整体,谓语动词用单数形式。
例如：How time flies! Three years is really a short time.时间飞逝!三年真是很短。
3、Last month,our dog welcomed me when I came home from school. 上个月,当我放学回到家时，我们的狗迎接我。
【解析】1）、welcome vt.欢迎:welcome sb.欢迎某人 welcome sb. to a place
欢迎某人到某地
例如：Let's welcome Tom.让我们欢迎汤姆。
2）、welcome adj. 受欢迎的，注意:要表达“欢迎某人做某事”时,应用:Sb.be welcome to do sth.
3）、welcome n. 欢迎。
【试一试】
1.They gave me warm .他们热烈欢迎我。
2.You welcome my pen,欢迎使用我的笔。
3.Welcome you China.欢迎你到中国来。
4.Thank you.谢谢。
-You .不用谢。
4、The minute I sat down in front of the TV,my mom came over.我一坐在电视机前,我妈妈就过来了。
【解析】英语中两个句子之间要用一个词连接起来，这个词就叫连接词。如果连接的句子是作状语，这个句子就叫状语从句。学过的状语从句的连接词有: when,while,before,after,till,until,as soon as,as(so) long as,as(so) far as, if, unless, because, as(随着;由于),so that。除了这些词外，还可用名词短语充当连接词。前面学过 every time, 这里出现了 the minute。

6、Could I borrow that book 我能借那本书吗 Could you lend me some money 你能借我些钱吗
【重点辨析】borrow vt.借:指借入。borrow sth（ from sb）（从某人那里）借入某物；lend vt. 借出，lend sth. to sb.把某物借给某人=lend sb sth；borrow,lend 都是瞬间动词,要表达借多久应用 keep。
【试一试】

I a book Tom.我从汤姆处借了本书。

4.Could you some money me 你能借些钱给我吗

11、he had no idea how to take care of himself.他不知道怎样去照顾自己。
【解析】have no(some)idea不了解/有些了解:后面可接 how to do sth. 或句子，因为是不确定不知道怎么做所以后面跟的是疑问句，而不是要去做某事（to do）已经确定目标目的的结构。
【试一试】
1)I have no idea to next.我不知道下一步要干什么。
2)I have idea that you are still here.我不知道你还在这里。

六、阅读理解。
Many kids do housework such as doing the dishes , making the bed, and folding the clothes. In exchange, they get some money or other computer time.
Paying kids for housework is one of the most popular topics(话题),especially at a time when everyone is more careful about money. Some parents think since adults are paid to do their jobs, we should pay kids for everyday housework
But some people don't think kids should get rewards(报酬)for doing housework. Susie Walton. an expert, believes that by rewarding kids, parents are sending a message that work isn't worth(值得) doing unless you get something in return.“Running any kind of housework is a team effort," Walton said.“A home is a living place for everyone in the family. It's important for kids to see that we're all a part of the family, and families decide how they want their home to look, and how they are going to keep it looking like what they want."
Other people believe that getting a reward encourages kids to do housework, and it also teaches them real world lessons about how we need to work to get money. There are also apps that give kids points and gifts that can be redeemed(兑现)either online or in the real world. Chris Bergman says," Kids need rewards to help encourage them."
( )1. The underlined phrase “ in return” in Paragraph 3 has the same meaning as“ ”
A. as a reward B.as a gift C.on sale D.under control
( )2. What is Walton's idea in the passage
A. Running exercise is a kind of team work.
B. People work to get some rewards.
C. Kids should do chores without rewards.
D.Doing housework is only parents’job.
( )3. According to Chris Bergman, kids should be encouraged to .
A. do housework without rewards
B.do more housework
C.stay away from housework
D.do housework by getting rewards
( )4. Which is the best title for the passage
A. Kids Should Study as Well as Doing Housework.
B. Let Children Do Some Housework.
C.Should Kids Be Rewarded for Doing Housework
D.Doing Housework Is Good for Children's Study.
