英语阅读理解--科普知识与现代技术(6)

 谷哥说英语 2022-04-01

学生在处理相关的科技类语篇时,尽管对很多科技信息也都有所耳闻,甚至熟知,但是在处理阅读理解过程和解题过程中总会出现或多或少的误解和误判。究其深层次原因,除了生词短语因素,还与学生专业领域知识匮乏、具体语境识别、整体篇章结构不无关系。那么针对科普类别的短文,教师在课堂教学中如何处理才能高效培养学生的阅读速度和理解力呢?

       通常我会要求学生在老师处理文本前,从七个方面着手:

阅读理解文本“七步走”

  1. 划出专业词汇和短语;

  2. 划出高级词汇和短语;

  3. 划出重点句式、句型;

  4. 划出长句、难句;

  5. 标注重点、疑问;

  6. 划出篇章结构;

  7. 归纳整理笔记

Task 6: 请搜索自己做过的科普类阅读练习题,按照上述方式和步骤进行阅读理解、深度学习、设置问题和相关干扰项。

Imagine a cat that does not need someone to clean up after it keeps an older person company and helps them remember to take their medicine. That is the shared dream of the toy maker Hasbro and scientists at Brown University in Providence, Rhode Island. The researchers received a 3-million-dollar award from the National Science Foundation for a special project. They want to find ways to add artificial intelligence, or A. I., to Hasbro's "Joy for All" robotic cat. 

The cat has already been for sale for two years. Though priced over 1,000 dollars, it sold quite wellIt was meant to act as a "companion" for older people. Now the project is aimed at developing additional abilities for the cat. Researchers at Brown's Humanity-Centered Robotics. Initiative are working to decide which activities older adults may need the most. They hope to make the cat perform a small number of activities very well. Such activities include finding lost objects and reminding the person to take medicine or visit their doctor. They also want to keep the cost down to just a few hundred dollars.

It is an idea that has appealed to Jeanne Elliott. Her 93-year-old mother Mary Derr lives with her in South Kingstown. Derr has dementia(痴呆). The Joy for All cat that Elliott bought this year has become a true companion for Derr. The cat stays with Derr and keeps her calm while Elliott is at work. Elliott said a robotic cat that helps her mother to remember to take her medicine and be careful when she walks would be greater.

The researchers are trying to learn how the improved cats will complete helpful activities and how they will communicate . They say that they do not want a talking cat , however. Instead they are trying to design a cat that can move its head in a special way to successfully communicate its message. In the end, they hope to create an exchange between the human and the cat in which the human feels the cat needs them. By doing so, the researchers hope they can even help prevent feelings of loneliness and sadness among elderly people.

1. What's the purpose of the project?

2. Compared with the old model , the new robotic cat will be _ .

3. What does Paragraph 3 intend to tell us?

4. What can we infer from the last paragraph?

Electric cars are dirty. In fact, not only are they dirty, they might even be dirtier than their gasoline-powered cousins. 

People in California love to talk about "zero-emissions(排放)vehicles", but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators(发电机). Generators are fueled by something--usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal(地热)plants as well, but by far we get electricity mainly by burning something.

In other words, those "zero-emissions" cars are likely coal-burning cars. It's just because the coal is burned somewhere else, it looks clean. It is not. It's as if the California Greens are covering their eyes -- " If I can't see it , it's not happening . " Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat--at the generator, through the transmission lines, etc. 

A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far-- so electric cars burn more fuel than gasoline-powered ones . If our electricity came mostly from nukes or geothermal , or hydro or wind or solar , then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources. 

In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads . When it's a power plant , though , all the junk is in one place . Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.

1. What is the main idea of the text?

2. The electricity we get from a gallon of gas may make our car run___

3. According to the text,electric cars_____

4. It can be inferred from the text that______

我的思考:

1. 请比照“七步走”,深度学习两篇文本;

2. 请思考两篇文本的主旨并画出篇章结构;

3. 请思考针对两篇文本的问题设置角度并设计相关干扰效项;

4. 请比对两篇文本的专业词汇、短语与上述三篇文章有否异同;

5. 请另外再寻找两篇或多篇科普类文本进行阅读并思考:英语的阅读训练或学习过程,能否使用或借鉴语文阅读中的“群文阅读”?
