一、目地与要求：
掌握本单元所出现的单词和词组，如：
at present common until recently year by year one day similar deer increase one after another等…
二、知识要点
(一)现在进行时的被动语态：
构成形式：be +being +done (过去分词)
如：The life of the milu deer is being studied at present.
More milu deer are being moved to a new large nature park.
(二) It作形式主语的句型：
It is hoped that…
重点与难点分析：
1. Where are you traveling to?
你打算去哪儿旅行？
本课中有几个句子的谓语动词是用现在进行时态，而表示将来的动作。如：
How are you getting there? =(How will you get there? )你打算怎样去那儿？
How many of you are making the trip? =(Why will you make this journey? )你们为什么要
做这样的旅行呢？
可以这样用的动词有：go, come, leave, arrive, stay, start等。
2. make/ take a trip/ journey 意思是“去旅行”。
go/ be on a trip/ journey也是“去旅行”。
We will make a trip abroad next month. 我们下个月要到国外去旅行。
She will take a long journey to London next year. 明年她将去伦敦做一次长途旅行。
They are planning to go on a journey around the world. 他们计划做一次球球旅行。
在以上各句中“trip”和“journey”都是名词，另外travel也作“旅行”解。既可以作名词，也可以作动词。例如：
Travel in the mountains can be slow and dangerous. 在山区旅行有时又慢又危险。
Travel broadens the mind. 旅行能使人见多识广。
We traveled all over the country. 我们游遍了全国各地。
It is much faster to travel by plane. 乘飞机旅行速度更快。
I love (to go) traveling. 我喜欢旅行。
3. …so that the number of these deer in China can be increased.
句中的“deer”是单复数同形的名词，单复数相同的名词还有“sheep, fish.”.例如：
How many deer are there in the Zoo? 动物园里有多少只鹿？
“How many sheep can you see in this picture?” “Only one (Sheep).”
“这张画里你看到多少只羊？”──“只有一只。”
“How many fish have you caught?”
“I’ve caught three fish.”
“你捉住几条鱼？”
“我捉了三条。”
但fish也有复数形式。用复数形式时，特指不同种类的鱼。如：
There are many kinds of fishes in the sea.
4. That sounds a great idea.
那听起来真是个好主意。
句中“sound”意思是“听起来”，是行为动词，但在此句中的用法，主它已失去行为动词的意义，实际上起联系动词的作用。学过的类似动词还有look看上去，feel摸起来，smell闻起来，taste尝起来，seem好像，等等。例如：
He looks very happy. 他看上去很快乐。
This kind of cloth feels very soft. 这种布料摸起来非常柔软。
The dinner smells good. 这饭菜闻起来很好。
His explanation sounds all right. 他的解释听起来似乎有理。
This soup tastes too much of garlic. 这汤尝起来大蒜的味道太重。
5. Good luck with your trip. 祝你们旅途顺利。
“Good luck”是表示祝愿的交际用语，有“走远”，“交好运”的意思。常用在分手道别时。在“Good luck”后可跟介词短语“to sb”或 “with sth”，表示“祝某人走运”或“祝某事顺利”的意思。例如：
Good luck to you. 祝你走运。
Good-bye: Good luck with your performance. 再见！祝你演出成功。
6. The milu deer is a Kind of deer that used to be common in China long ago.
麋鹿在很久以前是中国一种常见的鹿。
“used to ”是表示“过去”的意思。例如：
I used to smoke but not now. 我过去抽烟，但现在不抽了。
He used to get up at seven, but now he gets up at six. 他过去七点起床，但现在他六点就
起床了。
There used to be a bus-stop at the corner of the street, but now there isn’t.
过去在这条街的拐角处有一个公共汽车站，但现在没有了。
He used to be very strong when he was young. 他年青时，身体非常健壮。
另外，“be used to do”意思是“被用来做某事。”“be used to sth/ doing sth”是“习惯于某事”或“习惯做某事”的意思。注意分辨它们之间的差别。例如：
Wood can be used to make desks and Chairs. 木头可以被用来制做书桌和椅子。
He is used to hard work. 他已习惯于艰苦的工作。
I’m not used to being spoken to in that rude way. 我不习惯于别人那么粗鲁地对我说活。
I’m not used to the weather here in Beijing now, but I think I’ll get used to it soon.
我现在还不习惯北京这儿的天气，但我想我很快就会习惯的。
Until recently, the only milu deer alive in the world belong to the Duke of Bedford in England.
直到不久以前，世界上仅有的活着的麋鹿属英国贝德福公爵所有。
A: until可作介词或连词。作介词时，后面常跟名词或副词，构成介词短语。作连词用时，引导一个时间状语短语。作连词用时，引导一个时间状语从句。例如：
He studied in the library until 12 o’clock. 他在图书馆一直学习到12点。
Please wait for me here until I come back. 请在这儿等我，一直等到我回来。
Let’s wait until the rain stops. 咱们等到雨停吧！
Until then, no one but me knew anything about it. 直到那时，除了我还没有人了解此事。
They talked about the project until very late. 关于这项工程，他们一直谈到很晚。
B: the only milu deer alive =the only milu deer that were alive (仅有的活着的麋鹿)，句中的alive是形容词，作“活着的”解。通常用作表语。当作定语时，则要放在所修饰的名词后。例如：
He was badly wounded but was still alive. 他受了重伤，但还活着。
Who’s the greatest man alive? 谁是当今最伟大的人物？
There are not many pandas alive in the world today. 现在世界上活着的熊猫并不多。
类似的表语形容词还有：awake (醒着的), asleep (睡着的), afraid (害怕的), alike (相似的),等等。
8. at present =at the present time目前，现在例如：
We do not need any help at present. 目前，我们不需要任何帮助。
They are preparing for the examination at the present time. 现在他们正在为考试做准备。
9. Since then the number of milu deer there has greatly increased.
从那以后，那儿的麋鹿的数量已经大大增加了。
1) the number of …意思是“……的数目”，a number of …意思是“一些”，例如：
The number of students in their class is fifty. 他们班的学生人数是50人。
A number of students are playing football on the playground now.
现在有一些学生正在操场踢足球呢。
2) increase在句中是被用作不及物动词，作“增加”解，它也可用作及物动词，词意相同，例如：
Because of the wildlife project, the number of milu deer has increased.
由于这项野生动物保护工程，麋鹿的数量已经增加了。
Travel increases one’s Knowledge of the world. 旅行使人增加对世界的了解。
He increased his speed to overtake the lorry. 他加大速度以超过前面的卡车。
At all these centres it is hoped that one day they will have enough animals to set them free
and let them live in the wild again. 在这些研究中心，人们希望有一天他们会有足够多的麋鹿可以放出去，让它们重新回到野外去生活。
1) It is hoped that …本句中it是形式主语，真正的主语是that引导的从句。意思是“人们希望…”相当于（people hope that…）。例如：
It is hoped that the number of milu deer will greatly increase very soon.
人们希望麋鹿的数量将会很快增加。
It was hoped that the helicopters would land on the roof of the building. But the smoke was
too thick. 原本希望直升飞机能在大楼楼顶着陆，但是烟太浓了。
类似的句型还有：
It is said that …(Somebody says that…)据说…
It is believed that …(People believe that …)人们相信…
It is supposed that …(People suppose that …)人们认为…
It is reported that …(Somebody reports that …)据报导…
例如：
It is said that our new school-house will be built here. 据说我们的新校舍将建在这里。
It is reported that seven people lost their lives in the traffic accident yesterday.
据报导，在昨天发生的交通事故中有7人丧生。
2) one day既可指“将来的某一天”，也可指“过去的某一天”。例如：
It is hoped that one day the milu deer will be set free to the wild.
人们希望这些麋鹿总有一天会被放回到野外去的。
I’m sure you’ll be able to come to visit our country one day.
我相信，将来有一天你会到我们国家参观访问的。
One day on my way home, I met professor wang.
有一天，在回家的路上，我遇到了王教授。
11. So once more there will be milu deer living in the wild in China.
因此，中国将会再有生活在野外的麋鹿了。
1) once more =once again作“再一次”，“重新”解，例如：
Don’t be so disappointed. You may try once again.”
不要这么灰心丧气的，你可以再试一次。
Will you please explain it to me once more?
请你再给我解释一下好吗？
2) 句中的living in the wild in China是分词短语作定语，修饰前面的名词deer，相当于一个定语从名（…that live in the wild in China）。例如：
The girl standing by the window is my classmate. =The girl who is standing by the window is
my classmate. 站在窗户旁边的那个女孩是我的同班同学。
