主 题
9BU1 Asia(上) 及it用法
教学内容




亚洲（字源古希腊语：Ασία；拉丁语：Asia），曾译作“亚细亚洲”和“亚西亚洲”，是七大洲中面积最大，人口最多的一个洲。其覆盖地球总面积的8.7%（或言总陆地面积的29.4%）。人口总数约为40亿，占世界总人口的约60.5%（2010年）。
亚洲是全世界人口最多的一个洲，同时也是人口密度最大的洲。它的名字也最古老。全称是亚细亚洲，意思是“太阳升起的地方”。其英文名为Asia。相传亚细亚的名称是由古代腓尼基人所起。频繁的海上活动，要求腓尼基人必须确定方位。所以，他们把爱琴海以东的地区泛称为“Asu”，意即“日出地”；而把爱琴海以西的地方则泛称为“Ereb”，意为“日没地”。Asia一词是由腓尼基语Asu演化来的，其所指的地域是不很明确的，范围是有限的。到公元前一世纪Asia已成为罗马帝国的一个行政省的名称，以后才逐渐扩大，包括现今整个亚洲地区，成为一个世界最大的洲名。
亚洲的历史和文化都非常悠久。世界四大文明古国中的中国、印度和古巴比伦都位于亚洲大陆。亚洲的经济和文化水平曾经在世界上长期居于领先地位，中国的四大发明、印度人发现“0”、发明阿拉伯数字等等，许多科学上的发明创造，都为世界做出了巨大贡献。
批注:通过对亚洲的介绍，让学生对亚洲有基本的认识，导入本次课的主题——Asia。

知识点1. Wow, the Great Wall is amazing, isn’t it?
一、反意疑问句：
1)反意疑问句表示说话人对所陈述的事情有所怀疑或不肯定，想通过对方的回答来加以肯定或否定。
陈述部分肯定句+疑问部分否定句（可记为前肯后否）
陈述部分否定句+疑问部分肯定句（可记为前否后肯）
① —You are a teacher, aren’t you? 你是个教师，是不是？
—Yes, I am. /No, I’m not. 是的。/不，我不是。
②—She was here yesterday, wasn’t she? 她昨天在这里，是不是？
—Yes, she was. /No, she wasn’t. 是的。/不，没在。
2)对于这种形式的反意疑问句作回答的时候，不要过分注重问句中的否定词not在前还是在后，只要事实是肯定的，就用Yes，如事实是否定的，就用No。用Yes回答，后面就不能再用not，用No回答，后面就必须有not，这种情况与中文的表达习惯很不一样。请注意下面例句中中英文在表达上的差异。
① —Your sister isn’t coming back today, is she? 你姐姐今天不会回来，是吗？
—Yes, she is. /No, she isn’t. 不，她今天会回来。/是的，她今天不会回来。
② —You can’t do it well, can you这事你做不好，是吗？?
—Yes, I can. /No, I can’t.”不，我能做好。/是的，我做不好。
③—There wasn’t a football game on TV last night, was there? 昨晚电视里没有足球赛，是吗？
—Yes, there was. /No, there wasn’t.不，有足球赛。/是的，没有。
3)陈述句中含有never, few, little, hardly, nothing, nobody等具有否定含意的词，后面疑问部分应用肯定形式。如：
① You never saw Mr King before, did you? 你以前从未见过金先生，是吗？
② There are few apples left on the tree, are there? 树上没剩几个苹果了，是吗？
③ He has little money for food, does he? 他几乎没钱买吃的，是吗？
④ Little Mary can hardly walk by herself, can she? 小玛丽还不太会自己走路，是吗？
⑤ There’s nothing in that box, is there? 盒子里什么也没有，是吗？
⑥ Nobody saw you do it, did they？ 没人看到你干这事吧，是吗？
批注：提醒学生，当陈述部分含有否定意思的词是unhappy, dislike, unfriendly等含有否定词缀的派生词，也就是有un, dis, no-前缀、-less后缀等含有词缀而意思否定的词，当做肯定句处理，疑问部分要用否定形式。

2）amazed用作形容词时，意为“感到惊异或者吃惊”，是人对事物所产生的感受，它的意思接近surprised。在句中常作表语，其主语往往是人。如：

② I was amazed at her knowledge of space. 她丰富的太空知识令人大为惊讶。

it 的用法
知识点1：It 用作形式主语
当不定式（短语）、动名词（短语）或从句在某个句子中作主语时，为保持句子结构前后平衡，避免头重脚轻，因此常用it作形式主语置于句首，而将真正的主语放在句尾。此时it只起先行引导作用，本身无词义。
e.g. It is wrong to tell a lie.
It is no use arguing about it.
(争吵是没用的。) 〔It为arguing about it的形式主语〕
It is uncertain who will come.
(谁要来还不确定。) 〔It为who will come的形式主语〕
It 作形式主语的常见句型：
① It + be + 形容词 + to do sth. / doing / that ….
e.g. It is very important to learn a foreign language.
It is useless crying over the spilt milk.
It was really surprising that she married a man like that.
② It + be +名词词组 + doing / that ….
e.g. It is no good telling lies.
It is a pity that you didn’t go to see the film yesterday.
It is a truth that there would be no new China without the Communist Party.
③ It + be + 过去分词 + that ….
该句型常见动词有：say, hope, think, suppose, expect, report, know, believe, decide, etc.
e.g. It is said that they have invented a new type of computer.
It is believed that China will become one of the strongest countries in the world.
It was reported that more than 170 thousand people died in the 2004 tsunami.
④ It + seems / appears / happens等不及物动词 + that ….
e.g. It seems that he enjoys pop songs very much.
It appears that Tom might change his mind.
⑤ 若句子是疑问形式，就只能用it作形式主语。
e.g. Does it matter much that they won’t come tomorrow?
Is it true that he will go abroad next week?
⑥ It + takes + (sb.) + some time + to do sth.
这是一个表示“（某人）花多少时间干某事”的句型，其中it是形式主语，代替后面的不定式（to do sth.），句型中的sb.也可以省略。
e.g. It took me some time to read the reading materials.
It took him fourteen hours to go to New Zealand from Shanghai by plane.
How long does it take you to go to Beijing from Qingdao by train?
I am not sure, but I think it takes at least nine hours to get there.

知识点2：It 用作形式宾语
当不定式（短语）、动名词（短语）或从句在某个句子中作宾语时，为保持句子结构平衡，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾。此时it仍只起先行引导作用，本身无词义。
下列四种情况须用it 作形式宾语：
① 当不定式（短语）、动名词（短语）或从句在复合宾语结构中作某些动词的宾语时（如think, make, find, consider, feel, suppose等）；
e.g. They found it pleasant that they worked with us Chinese.
I don’t feel it difficult to understand the Special English.
He makes it a rule never to borrow money.
I think it no need talking about it with them.
② 某些表示“喜、怒、哀、乐”的动词，如like, enjoy, love, hate等，往往不能直接接宾语从句；
e.g. I don’t like it that he’s so lazy.
I hate it when my mother asks me to eat eggs.
③ that引导的宾语从句不能直接作介词的宾语；
e.g. You may depend on it that we shall always help you.
Would you see to it that she gets home early?
He insisted on it that he was innocent.
④ 由及物动词与介词组成的固定搭配中，宾语从句若作该动词的宾语时，须借用it。
e.g. I leave it to your own judgement whether you should do it.
We owe it to you that there wasn’t a serious accident.

A young waitress named Mary watched him move towards a table by the window.  She ran over to him,and said with a smile, “Here,sir.  Let me give you a hand. ” Without saying a word,he gave her a smile.  She pulled the chair away from the table and helped him sit down.  Then she put his cane against the table so that he could reach it. In a soft, clear voice, he said, “Thank you,miss. ”
“You're welcome,sir, ” she replied.  “I’ll be back in a moment, and if you need anything, just wave at me! ”

There's much to see under the sea, but you need to remember that light behaves differently in water than in air. The objects appear closer to you than they exactly are. You might find yourself reaching out to touch something and completely missing it.
Objects under water will appear larger than they would on the surface, too. Be careful not to tell any stories about the big fish that got away. That fish might not be so big after all! It's just because sometimes things can seem to be as much as about 33 percent bigger in water!
What's more, in deeper water, colors just don't seem as bright. In fact, it looks as if some colors are missing. Remember the color of an object results from the wavelengths（波长）of light that are reflected（反射）from its surface. And light is taken in as it moves down through the water.
Swimmers wear wet suits to keep warm underwater. Let's take a bright red, yellow, and blue wet suit as an example. These colors are hard to miss on the surface of water. Watch carefully the changes in color as you descend in the water. The red part now looks almost black because the red light wavelengths, the longest among these three colors, are missing. As you go down deeper, the same thing will happen to the yellow part and in the end to the blue part. Even at a place of about 6 to 9 meters underwater, you will look terrible, like a ghost（鬼怪）! And you have to wait for your return to the surface to enjoy the bright colors again!
