“Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. “There is certainly a lot of energy in waves,” he said. Scientists are working to use that energy to make electricity. Most waves are created when winds blow across the ocean. “The wind starts out by making little ripples(涟漪), but if they keep on blowing, those ripples get bigger and bigger and turn into waves,” Taylor said. “Waves are one of nature’s ways of picking up energy and then sending it off on a journey.” When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine(涡轮机). The turbine can then power an electrical generator to produce electricity.
“The resource is huge,” said Janet Swain of the World Watch Institute. “We will never run out of wave power.” Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three quarters of the Earth’s surface—that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.
Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic. Traditional sources of energy like oil and gas may someday run out. “Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world,” Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!

生活感悟类阅读解题指导:
一、文章特点:
生活感悟类的文章就是指能给人心灵以启迪,使人从中受到教育的文章。这类文章的体裁可以是记叙文,如生活中一些感人故事或情感故事,有点类似心灵鸡汤一样的短文。有时故事的结尾会有一句“点睛之笔”,点出全文的中心思想,就像《伊索寓言》里的寓言一样。还可能是夹叙夹议的哲理散文或生活随笔。散文随笔通常会阐述一种朴素易懂,耳熟能详的人生道理或宝贵品质。文章的结构和议论文类似,一般是总分总或总分结构。每段首句或尾句为主题句(论点),其它句子围绕主题展开论述(论据),论证方法多种多样,或举例,或引用名言,或正反对照等。
二、解题技巧:
针对生活感悟类文章的特点,做这类文章的完形填空时,要特别注意以下几点:
1、重点理解全文的首句。如果是记叙文,找出when,where,who,what等基本要素。如果是散文随笔,充分理解文章的中心句—全文的主题。
2、阅读全文的结尾段或结尾句,有助于理解文章所阐述或蕴含的哲理、感悟或忠告等。
3、调动自己的背景知识和情感。这类文章不会讲大道理也不会涉及到一些很专业的知识技术领域,而是谈一些小事和简单的道理,所以如果读者能和作者产生感情上的共鸣,读者会更好地把握作者的意图态度,从而提高做题的准确度。因此,考生在平时要做一个有心人,即用心去感悟生活中发生的小事,思考人生的一些基本道理,多阅读一些短小精悍的美文,多写写自己的心情故事和对生活学习的感悟。只有平时多用心,做题时才能调动自己的背景知识和情感。

You need to change in order to grow. Changing your life is a continuous process. It never ends. The moment you stop changing, you stop growing. Here are some tips that may help to change your life:

To change your life, you need time to think and reflect. If you are always busy, you won’t have the time to think about your life, let alone taking action to change it. It’s not only the scenery you miss by going too fast ― you also miss the sense of where you are going and why.

It’s your life; nobody can change it but you. If you aren’t willing to change, then nothing in this world can make you do so. To build the willingness to change, first you should realize that your life can be better than it is now. No matter how good your life is, it can always be improved. On the other hand, don’t feel hopeless if your life doesn’t seem good right now. You can always change your life for the better.
Don’t blame other people for the bad things that happen in your life. Don’t blame your family, friends, boss, or the economy. Whether your life goes up or down depends on you and you alone. Stephen Covey once said, “We immediately become more effective when we decide to change ourselves rather than asking things to change for us.”
