We are now living in the modern society. Most of the energy we use for heating, lighting, transportation and manufacturing (制造业) comes from fossil (化石) fuels. These are carbon-based fuels from oil, coal and natural gas. When we burn these fuels we release heat which p__1.___ the energy.
There are three main disadvantages to using these fuels. Firstly, they are causing climate problems because of the G_2.___ Effect. When we burn fossil fuels they produce carbon dioxide which causes global warming. Secondly, when we have used up all our coal, oil and natural gas, we will have n__3.__ left to burn. Thirdly, they are not very efficient. The internal combustion engine (内燃机) that we use in most cars, trucks and buses, for example, is only about 14% efficient.
Scientists are working on another fuel—hydrogen. There are a couple of advantages to using hydrogen as a fuel. Firstly, because two-thirds of the e__4.__ surface is water and water is made of hydrogen and oxygen. There is an almost unlimited supply of hydrogen. Secondly, burning hydrogen does not cause global warming. Thirdly, it is much more efficient than carbon-based fuels.
Unfortunately there are problems with hydrogen at the present time: there is the problem of separating (分离) it from water c_5.___, and there is the difficulty of storing it. It can be stored under pressure but high pressure tanks are far from safe. It can also be stored as a liquid but only at extremely low temperatures. It seems likely, therefore, that there will have to be a completely new technology before hydrogen replaces fossil fuels. S__6.___ these problems is an urgent (急迫的) matter. Although China, India and Australia have huge amounts of cheap coal, and there are still l__7.___ oil and gas reserves(储藏量) elsewhere, the effects on the planet’s climate will be bad if they are used.
"Uncle Sam," is usually used to refer to the United States or the US government. It is the nickname of the country.It is hard to believe that this nickname became known quite by accident and there was a man 75 "Uncle Sam."However,not many people have ever heard of such a man.Not even most young Americans.
The man was called Uncle Sam Wilson.He was born in Arlington,Massachusetts, September 13, 1776. At the age of 14 Sam joined the American Revolutionary War(美国革命）, and 76 in the army under George Washington until the end of the war.He then moved to Troy, New York states, and began a meatpacking business. He earned a reputation（赢得了声誉）for being honest and hardworking. He was locally respected and admired, thus greeted as Uncle Sam.
One day in 1812,a group of visitors came to Sam's meatpacking plant(肉类加工厂）.Among them was Government official. He 77 the capitalized letters(大写字母） EAUS on the packages of meat and asked what they stood for. A worker man replied that EA stood for Elbert Anderson,the businessman for whom Sam was working.And he added 78 that US(actually it was the short form for United States) stood for Uncle Sam Wilson. Soon soldiers were saying all army supplies were from "Uncle Sam".
In May 1813,this story appeared in a newspaper published in New York.Since Uncle Sam was an example of a hard-working man and a lover of America, the idea of"Uncle Sam" as the name of this kind of man became well-known rapidly.Uncle Sam was ready to help 79 and place the interest of the nation(国家利益）above all---this is in line with (与……符合）the American spirit. This makes the American consider Uncle Sam 80 the symbol of the USA.In 1961 the US Congress made a decision that "Uncle Sam" is the America's national symbol.

I had to make a big decision. Five years ago, I was working for a small engineering company. However, things were not going very well for the company and it was losing money. One day, the boss told us that the company was 1. business. We were all unemployed.
That lunch time we went to the pub 2. . We were all very sad.Well,of course, we talked about the problem. Then the landlord of the pub heard the news. He said, "Why don't you buy the company?" At first we all laughed,but then we started to discuss it 3. . We knew the problems. The company had lost a lot of customers because it hadn't developed new products, but finally we decided to go for it.
So we bought the company. The first few years were very 4. . But we worked hard and we had a bit of luck. We began to improve three years ago. Since then we have done pretty well. Last year we took on(招聘)four new people. And so far we haste taken on another ten.
