1. doing的形式：doing; being done
2. doing做主語，表語和賓語。
3. doing與to do在動詞后面做賓語的區別
知識總結歸納：
（一）動詞ing形式起名詞作用，在語法中也稱做動名詞．在句中做主語，賓語，表語和定語。它的基本形式有doing; being done。
例句：
1. Parking is difficult in the shopping center of the city.
2. My favorite job is teaching English.
3. His main hobby is collecting stamps.
4. Denying this will be shutting one’s eyes to fact.
5. I suggest you should practise speaking English whenever you can.
6. Hearing what I said, he couldn’t help laughing.
7. Did you see that car being repaired ?
注：to do形式也可以做主語或表語。一般情況下，這兩種形式做主語或表語，差別不是很大。但是如果刻意強調某個具體的動作，就用to do 形式， 而要表示一般性或泛指的動作則用doing形式。
例如：
1. It is difficult to park in the shopping center at the weekend.
2. My duty is to take care of the baby while she is out.
（二）在一些動詞后面只能接動名詞做賓語。后面跟doing做賓語的常見動詞有：admit; advise; appreciate; avoid; complete; consider; deny; mention; mind; miss; prevent; delay; enjoy; escape; imagine; postpone; practise; risk; suggest;常見的動名詞短語，如：be worth doing; can’t help doing; look forward to doing; go on doing; insist on doing; prefer doing to doing; be busy doing; keep on doing; devote…to doing; spend…in doing; have difficulty in doing; have a good time doing; prevent…from doing
1. I am looking forward to hearing from you soon.
2. He has devoted himself to protecting the wildlife.
3. He is trying to avoid answering my question.
4. The accused man denied ever having met her.
5. He insisted on sending for doctor at once.
6. The film is well worth seeing.
7. You can’t imagine the difficulty we had making a little money.
（三）doing形式的邏輯主語：當強調doing所表達的動作的執行者（邏輯主語）時，需要在doing前面加上物主代詞，人稱代詞賓格，名詞所有格或不定代詞
例句：
1. I’m surprised at your/you doing it.
2. She insisted on their both accepting the invitation.
3. Do you mind my opening the window ?
4. Your being right doesn’t necessarily mean my being wrong.
5. The children are looking forward to spring coming.
6. He disapproved of that being said about Jane.
7. Mr. Carson complained about Tom and Mary coming to class late.
（四）doing與to do在動詞后面做賓語的區別:
remember/forget to do：記住/忘記了去做某事
Don’t forget to do sth.=remember to do sth.
regret to do: 遺憾地去做/說 regret doing: 后悔做了某事
mean to do= want to do mean doing 意味著做
stop to do: 停下來去做 stop doing 停止/不去做
try to do: 試圖/努力/企圖去做 try doing: 嘗試用一種方法做
go on to do 接著去做另一件事 go on doing: 繼續把事情做下去
例句：

2. I don’t remember having said anything of the sort.
3. I regret to say that you have failed in the exam.
4. He tried to walk without a crutch.

三. 閱讀理解：
We are all familiar with domestic trade. When I buy Florida oranges or California shirts, I naturally want to pay in dollars. Luckily. the orange grower and the shirt manufacturer are willing to accept U.S. dollars for their expenses. Trade can be carried on in dollars. Economic transactions within a country are relatively simple.
If I want to buy a British bicycle, however, matters become more complicated. I must ultimately pay in British money, or "British pounds,” rather than in dollars. Similarly, if the British want to buy U.S. merchandise, they must obtain U. S. dollars. And the requirement to obtain foreign currencies bolds for other countries as well.
We see, then, that international trade introduces a new element: the foreign exchange rate, which denotes the price of a foreign country's currency in terms of our own.
Here are some examples: The U. S. dollar price of a British pound was recently $ I. 80; for a British resident wanting to buy U. S. goods, the price of a dollar was 1/$1.80= 0.56. There is also a foreign exchange rate between U. S. dollars and the currency of each and every country, In mid-1988, the foreign exchange rate was 60 cents for a German mark, 18 cents for a French franc, 80 cents for a Canadian dollar, and 0. 8 cent for a Japanese yen. For foreigners desiring to buy dollars, the reciprocal prices were 1. 67 German marks. 5. 56 French francs, 1.25 Canadian dollars, or 125 Japanese yen for each U.S. dollar.
Given the foreign exchange rate, it is now possible for me to buy my English bicycle. Suppose its quoted price is , 100（i.e. , 100 British pounds）. All I have to do is look in the newspaper for the foreign exchange rate for pounds. If this is $1.80 per pound, I simply go to a bank with $180 and ask that the money be used to pay the English bicycle exporter. Pay with what? The bank pays with pounds, of course, the kind of money the exporter needs.
You should be able to show what British importers of American grain have to do if they want to buy, say a $ 36,000 shipment from an American exporter. Here pounds must be converted into dollars. You will see that, when the foreign exchange rate is $1.80 per pound, the grain shipment costs them 20,000.
Businesses and tourists do not have to know anything more than this for their import or export transactions. But the true economics of foreign exchange rates cannot be grasped until we find out why the foreign exchange rate is at a given level.

D. The foreign exchange rate is an element introduced to denote the price of a foreign currency in terms of the price of another foreign currency.
3. In mid-1988, how much dollars did one have to have in order to exchange for 10,000,000 Japanese yen?
A. 8,000,000 B. 80,000 C. 800,000 D. 80,000,000
4. What do British importers have to do if they want to buy $ 36,000 worth of grain from an American exporter?
A. They have to pay British pounds directly.
B. They have to pay French francs.
C. They have to convert 36,000 U.S. dollars into 20,000 British pounds.

B. do not have to know more the true economics of foreign exchange rates.
C. have to know nothing more than economics of foreign exchange rates.
