本单元重点难点分析

1. David and Joy, come on, were having a family meeting.

大卫、乔伊，快点，我们要开家庭会。

come on在此表示鼓励、挑战、恳求、要求等感叹语，可译作赶快;来吧;快点。例如：

(3)Come on. The film has begun.赶快，电影开始了。

2. Could you please tell me where we show our tickets?

你能告诉我们在哪里检票吗?

Could you...?句型中，Could不是过去形式，在此表示语气婉转、有礼貌。在希望得到肯定答复的疑问句中，以及在含有表示建议、请求和征求意见语气的疑问句中，常用some和something，而不用any和anything。

(1)Could you lend me your bike, please?

3.Could you tell us how long were going to be away?

你能告诉我们要去多久吗?

此句是由连接副词how long引导的宾语从句。要注意的是在以连接代词或连接副词引导的宾语从句中，从句的语序要用陈述句的语序。从句的时态要随主句的时态而变化。例如：

(1)Do you know what time the train leaves? 你知道火车几点离开吗?

(2)No one knows why he was late last night.

没人知道他昨天晚上为什么迟到了。

(3)I want to know how many English words you have learned.

4. Whats the number of the Smiths flight out of Beijing?

史密斯全家离开北京的飞机航班号是什么?

(1)flight是fly的名词形式，表示飞行;航班等。

例：Flight Number 6141 to Beijing is ready to leave.

去北京的6141次航班马上就要起飞了。

(2)out of从……出来(去)，相对的词为into。

如：come out of the room 从房间里出来。

go into the room 到房间里去。

5. take, spend, pay, cost

四个单词意思均为花费，使用。

take常用于It takes(took，will take)sb sometime to do sth;spend构成的句式中，一般以人做主语，句型为：spend…on sth或者spend… (in)doing sth;pay构成的句式中，一般以人作主语，常用句型为 pay sb for sth 为……付款给……，pay off…付完，偿清……;cost一般以物做主语，可以解释为花费;价值，它还可做名词，意思是价值，价格。

It took my uncle less than two weeks to plant the trees. But its worthwhile. You see, we paid nothing for all these trees, though they cost us more time and more energy. We spent almost 10 days last month searching everywhere, hunting for a farmer who is willing to offer us free supplies of young trees.

6.Then there are long white beaches to walk along.

along在这里是个副词，表示向前的意思。along作副词时，其前面的动词经常用的有：come, go, crawl, walk, drive, float, fly, move, hurry, pass, roll, run, swim等。例如：

Move along, please.请向前走!

Now, go along. 请直走!

Pass the note along.把条子传过去。

She walked along by himself.她一个人向前走。

The days glide swiftly along.岁月如梭。

Come along! 跟我来!

along 除表示上述意义之外，还可以作沿着。例如：

Look at the trees along by the river.看那边沿河的树。

另外，along还可以作介词用。along作介词时，常常的意思是沿着。例如：

We went for a walk along the road after supper.

晚饭后我们沿着公路散步。

Pass along the car, please! said the conductor.

售票员说：请往里走!

7.Lets see if we can find some information about that city.

咱们看一下是否能找到有关那个城市的一些信息。

Could you tell me whether thats a fast train or not?

请告诉我这是不是快车好吗?

这两句是由连词if和whether引导的宾语从句，意思是是否。如果将一般疑问句改为宾语从句时要用if或whether连词引导，宾语从句要用陈述句语序。从句的时态也应随主句的时态变化而变化。if和whether在通常情况下可以互换使用。

例如：

(1)Did you know if / whether he would come tomorrow?

你曾知道他明天是否回来吗?

(2)Mother asked if / whether we needed some more tea.

妈妈问过我们是否再要一些茶。

在下面几种情况下不能用if代替whether：

(1)当 whether与 or not连成一个词组时。例如：

I cant say whether it is going to rain or not.我不知道明天是否下雨。

(2)whether用在不定式前面时。例如：

He cant decide whether to go.他不能决定是否去。

(3)whether引导的从句放在句首时。例如：

Whether this is true, I cant say.不管是不是真的，我说不准。

(4)whether用在介词后面时。例如：

She is worrying about whether she can finish the work on time.

她正担心，她是否能准时完成工作。

8.Id like to book four tickets, please. 我想定四张票。

book在此是动词，意思是预定;买票。例如：

(2)Have you booked your passage to Shanghai? 你到上海去的舱位定好了吗?

(3)Could I book a ticket through to Hainan Island?

我能买一张直达海南岛的票吗?

9.That sounds really cool! 这听起来确实很酷!

sound是系动词后跟形容词作表语。类似用法的动词还有：get, turn, smell, taste, feel, look等。例如：

(1)It looks more beautiful in the sun. 在阳光下，它看起来更漂亮。

(2)The dish smells delicious.菜闻起来很香。
