1. With no light outside，it felt like midnight.

此句中介词with表示一种伴随状况，同时还包含着某种因果关系，表示“因某种状况的存在而导致…”，因此可翻译成“由于;由于”等。 e.g. I can’t work with all that noise going on. 由于那噪音响着，我无法工作。

2. Ben’s dad… while his mom was making sure the flashlights and radio were working.

1) 此句中的连词while的意思是“当…的时候;和…同时”，while还可以表示“而;然而;但”之意，用来说明和强调两种事情或情形不同。 e.g. Tom is active and outgoing while his sister Rosa is shy and quiet.

汤姆活跃外向，而他的妹妹罗莎却羞涩害羞。

2) make sure“确认，查明，核实;确保;设法保证”，其后可接句子，或接介词of及宾语，用来引入需要确认的内容。

e.g. Make sure you turn off the TV before you leave the house. 在你离开屋子前确认关闭了电视。

3) 此句中的work表示机器，器官等“运作，运转”，这是动词work的一种基本用法。

3. It was hard to have fun with a serious storm happening outside.

It is adj.+ to do sth. 做…怎么样。

It is adj. for sb. to do sth. 对某人来说做…怎么样。 e.g. It is important for us to learn English. 对我们来说学英语很重要。 活学活用：

Step 1 Greetings

Greet the students as usual. Step 2 A Game

Show a list of chores on the blackboard： do the dishes clean your room take out the trash sweep the floor fold your clothes make your bed Give them a set of blank cards.

T：Let’s play a game. You will work in groups of four. First each group writes the chores on the cards. Put them face down.

The first student turns over a card，and asks the student ne*t to him/her to do this chore. That student says “no” and gives a reason. Each student should give a reason that has not been given before. The one who can’t give a proper reason will be out of the game. Those who can keep coming up with reasons will be the winner. Step 3 Role play

Ask some pairs to role play the dialogue in 2d. Step 4 Presentation

Say：As we all know，Mother does almost all the housework in the house. She is always tired. Should we help Mother? What we can do to help her? Ask some students to report their answers. Step 5 Reading

Please read quickly and answer the questions：1. Why was Nancy’s mom angry with her? 2. Did they solve the problem? How? Then ask some students to report their answers.

Now let’s read the sentences in 3b，try to understand and translate them. Then read the passage again carefully and try to underline the sentences from the reading that mean the same thing. After several minutes， ask some students to report their answers and translate the sentences into Chinese. Step 6 Language points

1. You watch TV all the time and ...

all the time(在该段时间内)一贯;一直，一向;时时刻刻;每时每刻 e.g. I do this all the time. 我一贯是这么做的。 This happens all the time. 这种状况是时时发生的。 2. I’m just as tired as you are!

as ... as 意为 “和…一样”，表示同级的比较。运用时要留意第一个as为副词，第二个as为连词。其基本结构为：as + adj./ adv. + as。

e.g. This film is as interesting as that one. 这部电影和那部电影一样有趣。

Your pen writes as smoothly as mine. 你的钢笔书写起来和我的一样流畅。

留意：as … as 的否定形式为“not as/so + adj./adv. + as”。 e.g. He didn’t act as well as you. 他表现得不如你好。 3. For one week，she did not do any housework， and neither did I.

1) neither 用作副词，作“也不”说明，放在句首，表示前面否定的内容也适用于另一个人或物，句子须采纳部分倒装。此时也可用nor替换 neither 运用。

e.g. --- I don’t like this dress. 我不喜爱这件连衣裙。 --- Neither / Nor do I. 我也不喜爱。

留意：neither 之后的主语要置于助动词或系动词之后。 2) neither 用作代词，表示“两者都不，双方均不”。 He answered neither of the letters. 他两封信都没回。 e.g.--- Which one would you like? 你喜爱哪一个? --- Neither. 两个都不喜爱。 Step 7 Practice

3c, Show the sentences on the screen： 1. Could you take the dog for a walk? 2. I walked home from school. Then ask some students to read and translate them.

words in the sentences are verbs or nouns. Then write another sentence using the underlined word in the other form. Finally ask some students to report their answers. Step 8 Grammar focus

一节课下来，大部分同学都能积极投入到课堂教学中来，并积极举手发言。课堂气氛比较活跃，调动了大部分同学听课的积极性，因此合作教学对提高同学实际的语言沟通技能以及与他人的合作技能有很大的促进作用。但很明显，语言表达技能强的同学参加的机会相对要多，代

表小组汇报的机会也多，而另有一些同学却习惯于当听众，被动地接受别人的观点，很少发表自己的个人看法，也就是说在小组合作学习中同学的参加度不均衡，而这部分同学主要是学习困难生。
