题文


In summer, millions of people will head for the beach. And while the ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland.“There is certainly a lot of energy in waves.”
Scientists are working on using that energy to make electricity.
Most waves are created when winds blow across the ocean.“The winds start out by making little ripples (波纹) in the water, 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 towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (涡轮) .The turbine can then power an electrical generator (发电机) .
The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland.
The resource is huge.We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal.
Oceans cover three quarters of the earth’s surface.That would make wave power seem perfect for creating energy around the world.There are some drawbacks, however.
Jamie Taylor said that wave power still cost too much money.He said that its effects on animals in the sea were still unknown.Plus, wave power would get in the way of fishing and boat traffic.
With more research, however, “many of these problems might be overcome,” Taylor said.“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world.Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day.”
In the future, when you turn on a light switch, an ocean wave could be providing the electricity!
68.Which of the following is NOT true?
A.Wave power costs too much money.
B.Wave energy creates the same amount of pollution as other energy sources.
C.Wave power affects fishing and boat traffic.
D.Wave power may affect marine animals.
69.We can infer from the passage that ______.
A.finding more new energy sources is not necessary because of wave energy
B.wave energy is a resource that will never run out and is used all over the world
C.wave power is perfect for creating energy around the world
D.wave power doesn’t create any pollution
70.The underlined word “drawbacks” probably means ______.
A.regrets  B.adventures   C.disadvantages  D.difficulties
71.What can be the best title for the passage? 
A.How to Get Electricity by Waves.   B.The Advantages of Wave Energy.
C.Can Waves Make Electricity?  D.The Disadvantages of Wave Energy. 题型:未知难度:其他题型

解析

考点

据考高分专家说,试题“In summer, millions .....”主要考查你对 [日常生活类阅读 ]考点的理解。

日常生活类阅读

日常生活类阅读的概念:

日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作,生活以及学习情况。做这一类题时,最主要的是要把握好人物的活动内容,时间和地点。

日常生活类阅读题答题技巧:

【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小,追根溯源,探索各项风俗的历史渊源,内容有趣。命题也以送分题为主,如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松,试题做起来比较顺手,但绝不能掉以轻心。因为稍不留神,就会丢分。
【备考提醒】
为了保证较高准确率,建议同学们做好以下几点:
1、保持正常的考试心态。笔者在教学中发现,越是容易的试题,同学们越是容易失分。为什么呢?因为在这种情况下,同学们极易产生麻痹思想,认为题目好做,就不引起高度重视,于是思维不发散、不周密。而命题人就是利用同学们的这一弱点,设计陷阱题。所以,无论试题难易与否,我们都要保持正常的考试心态。试题容易,不欣喜;试题难,不悲观。
2、根据前面讲到的方法,认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义,确定多义词或短语在文中的意思,确认文中的某个代词所指代的对象,或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子,切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提,以具体事实为依据进行推理,做出判断。这种推理方式比较直接,只要弄清事实,即可结合常识推断出合理的结论。
