Do you know why people living in particular areas usually have a certain color? Biology and history are the two reasons for this. Skin contains something called melanin, which determines a persons skin color. The more melanin a person has, the darker his or her skin will be. The amount of and the production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with less sunlight, a persons body will produce less melanin, making the skin lighter.,Skin color is also affected by another source - vitamin D. humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a darkskinned person will produce less vitamin D than a lightskinned person when they received the same amount of sunlight. The connection between vitamin D production and skin color is clear when we look at evolution. The earliest humans lived in Africa, their dark skin produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. their skin gradually got lighter and they lost hair. Now, people living in areas with strong sunlight like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D. Evolution has given us a rainbow of skin colors. Humans have always had melanin to determine our skin color. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin color.,A World of Skin Color,高考任务型阅读解题的有效性- 表格式： 一、审题： 1、审题目要求。 、是否可用文中的词填写。 、弄清字数限制。 此任务阅读限定每个空格只填一个单词；对是否用文中的词填写没有限制即可用文中的词。 2、审任务设置类型。 、 表格式。（结构常为对比陈述；通常分左右栏，左栏为文章提纲右栏文章细节。） 此短文设置表格任务型。左栏为文章提纲：brief introduction、reasons、biology reasons、 historical reasons、conclusion；右栏为支撑每一topic的细节。 、 树状式。（结构常为先总后分；通常分上下框，上框为topic sentences,下框为supporting sentences。）,二、阅读： 读图表。（快速浏览，了解短文的写作提纲。） 浏览图表，了解：topic sentence 1 details topic sentence 2 details topic sentence 3 details topic sentence 4 details topic sentence 5 details 2. 读短文。 、快读：快速浏览全文，抓住文章主题，同时结合图表，洞悉文章结构。 Paragraph 1 Topic sentence 1 Paragraph 1 Topic sentence 1 Paragraph 1 Topic sentence 1 Paragraph 1 Topic sentence 1 Paragraph 1 Topic sentence 1,、细读：仔细阅读，获取充分信息，查出答题的对应信息点。 第一空paragraph 1归纳结构类词； 第二空对应信息点为why people living in particular areas usually have; 第三空对应信息点为biology and history are the two reasons for this,要求学同义转换; 第四空对应信息点为which determines a persons skin color; 第五空对应信息点为by producing more melanin, making the skin darker; 第六空对应信息点为skin color is also affected by another sourcevitamin D; 第七空对应信息点为 a darkskinned person will produce less;,第八空对应信息点为 having darker skin, while people ; 第九空对应信息点为paragraph 5 归纳结构类词； 第十空对应信息点为 had melanin determine our skin color.,三、答题。 结构类的词： 、 熟记常见结构类词汇。归纳掌握常见的表达文章结构的概括性词汇：introduction(导入)、cause/reason(原因)、advantage(优点)、disadvantage(不足)、attitude(态度)、result/effect/consequence(结果)、suggestion/advice/tip(建议)、及dos和donts等。 、 确定答案。 、联系图表左栏的上下栏，确定用词及词的形式。（大小写、单复数、动词+ing等） 、联系图表左栏与之相对应的右栏的细节，归纳结构类用词和词的形式。 （大小写、单复数、动词+ing等,2. 细节类的词： 、明确信息点。细读文章，明确答题的相应信息点在文中的具体位置，确定用词后归纳用词。 、上下前后。 、对照短文中的信息点，联系图表右栏的上下栏目，确定词（文中原词或归纳的词的形式。 （大小写、单复数、动词+ing等） 、对照短文中的信息点，联系所填词的前后，确定用词（文中原词或归纳的词）的形式。 敲定答案。根据短文信息点，联系填空上下前后，敲定答案。,第一空 introduction；第九空conclusion，联系图表上下前后开头字母大写、单数。 第二空信息点为areas, 联系前后搭配 a 故用area; 第三空同义转换 are lie; 第四空信息点为 which determines, 联系前后搭配 color is 转换为determined; 第五空信息点为 making the skin darker,故用darker; 第六空信息点为 is also affected by,联系前后句子结构故用affecting做后置定语。 第七空信息点为 will produce less vitamin联系前后 to, 故用原型produce。 第八空信息点为 skin, while people living in other , 故用while。 第十空信息点为 had melanin determine our 联系前后搭配故用plays。,四、检查。 检查单词的拼写、大小写、单复数、时态、语态等。 introduction area lie determined darker affecting produce while Conclusion plays,Thank you!,更多高考英语应试技巧及试题尽在 原上草教育资源网 http:/www.ysc365.com,
