拆散的解释Nothing Succeeds Without a Strong Will
It is known to us all that where there is a will, there is a way. A person can probably accomplish nothing without a strong will. We can"t deny that sometimes people can reach a goal by playing tricks; however, that definitely won"t last long.
People with strong wills cannot be defeated by difficulties easily and they will never give up until they succeed. Take Nobel, the inventor of explosive, as an example, before inventing explosive he took thousands of explosion experiments. We can name quite a lot of famous people like Nobel, but we can also list some people like the "smoking quitters". To them, making a plan is so easy as they don"t have to keep it. Therefore, they will never realize it.
To sum up, a strong will is an important character people should cultivate since it plays a key role in people"s success. The resolute make resolutions once and for all; the irresolute keep making resolutions all for once. To be the winner, try to be the resolute.

四、Passage One(总题数：1，分数：10.00)
Until the invention of the modern washing machine, most people washed their clothes by hand. In the 20th century, however, washing machine became common, and washing clothes became much easier. Washing machines, though, have some rious disadvantages. One is that they need a great deal of clean water. Another is that, in many countries, hot water is ud in the machines. This consumes a lot of energy. In the United Kingdom, for example, about one-third of houhold energy is ud for heating water, including that ud to wash clothes.
Now, a British company has invented a washing machine that solves the problems by using small plastic beads to absorb dirt and clean the clothes. First, a little water is added to the clothes to get them wet. Then, the beads are mixed with the clothes until they have taken away all the dirt and stains. When the process is over, the little beads are removed by the machine, and the clothes are left almost dry. Becau the beads can be ud over
and over, the machine costs very little to operate.
The new machine is bad on the rearch of Stephen Burkinshaw, a chemist at the University of Leeds in the U.K. For a long time, Burkinshaw has been studying ways to make plastic materials a different color. A few years ago, he noticed that many kinds of plastic, especially nylon, attract dirt in warm and wet conditions, the surface of the nylon remains clean. For this reason, beads made of nylon can be ud repeatedly until they are completely full of dirt.
nd it onThe new washing machine can save houholds a great deal of the money they spend on water and energy. At the same time, the machines are very good for the environment. The United States, for example, us 1.25 billion metric tons of water on washing clothes every year. If the new machines were adopted there, 90 percent of this water could be saved. The saving of electricity, meanwhile, would help decrea the amount of carbon dioxide produced by power plants. For the reasons, the company is hoping that its new "waterless" washing machines will be widely ud in the future.（分数：10.00）
