高中英语 Unit 5 t he power of nature 语法现代分词做状语导学案新人教版选修6t he power of nature 语法现代分词做状语导学案新人教版选修6【学习目标】现在分词做状语【课前预习】一、基本用法:现在分词的形式是“动词原形+ing”;分词的否定式在分词前加not (例如:not knowing, not having received); 现在分词做状语时表示的动作与谓语表示的动作(或状态)是同时或几乎同时发生,有时先于谓语的动作发生;它的逻辑主语与句子的主语一致;分词做状语一般与其他成分用逗号分开;分词可以做时间,原因,方式,条件,结果,目的,让步等状语。
二、现在分词的基本形式:动词形式与句子主语关系及含义以do为例一般式[来源:学、科、网][来源:学科网][来源:Z*xx*k、Com]主动式doing主动,进行[来源:Z*xx*k、Com]被动式being done被动,进行完成式主动式:having done主动,完成被动式:having been done被动,完成三、题型结构:_______________________,S+V+O、(多把表时间,原因,条件,目的状语等放句前)S+V+O,_________________________、(表结果,伴随的状语等放句后)逗号前后没有连词连接(and, but, when, as, where, however,等),就构成了非谓语做状语的基本前提,现在分词的主动式主要是与句中主语逻辑上的一种主谓关系,现在分词的被动式主要是与句中主语逻辑上的一种动宾关系;现在分词的进行式是指分词所表示的动作(或状态)与句中动作同时或几乎同时发生,现在分词的完成式是指分词所表示的动作(或状态)一定先于句中谓语动作发生。
Eg、1、Seeing from the hilltop, he was delighted to see a wonderful view、此句中,逗号前后无连词连接,故不能同时出现两个简单句,see 逻辑主语是 he,他们之间是一种主谓关系(主动),see 动作与be delighted to see几乎是同时发生,因此seeing(主动,进行)符合要求,相当于一个时间状语从句:when_______________________, he was delighted to see a wonderful view、2、 Having written an important letter, I listened to the music for a while、此句中write与I是逻辑上的主谓关系(主动),write动作先于句中listen to the music的动作,故用having written(主动,完成)作状语。

Life in the ClearTransparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between the surfaceof the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless they’re eating it, or unless something is eating them.”And they are as clear as glass. How does an animal become see-through? It’s trickier than you might think.The objects around you are visible becau se they interact with light. Light typically travels in a straight line. But some materials slow and scatter(散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.But a transparent object doesn’t absorb or scatter light, at least not very much, Light can pass through it without bending o r stopping. That means a transparent object doesn’t look very different from the surrounding air or water. You don’t see it ----you see the things behind it.To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments(色素) that absorb specific colors of light. But a transparent animal doesn’t have pigments, so its tissues won’t absorb light. Ac cording to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.Animals are built of many different materials----skin, fat, and more----and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extre mely flat. Without much tissue to scatter light, it is easier to be see—through. Others build a large, clear ma ss of non-living jelly-lie(果冻状的)material and spread themselves over it .Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exa ctly as much as water does. They need to look uniform. But how the y’re doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.63. According to Paragraph 1, transparent animals_______.A. stay in groupsB. can be easily damagedC. appear only in deep oceanD. are beautiful creatures64. The underlined word “dead” in Paragraph 3 means__________.A. silentlyB. graduallyC. regularlyD. completely65. One way for an animal to become transparent is to ________.A. change the direction of light travelB. gather materials to scatter light.C. avoid the absorption of lightD. grow bigger to stop light.66. The last paragraph tells us that larger transparent animals________.A. move more slowly in deep waterB. stay see-through even after deathC. produce more tissues for their survivalD. take effective action to reduce light spreading【解析】文章解释了生活在海洋的透明生物的特点,透明原理,以及形成机制.63.B细节理解题.文章第一段第三行:Most of them are extremely delicate and can be damaged by a simple touch.得知B选项:透明动物是很容易受伤的.故选B. 64D词义猜测题.该词出现在文章第三段第三行.前文提到了:你能看到的物体一种是对光线进行了散射,而另外一种是对光线的吸收.既然吸收了,那在光的传播过程中就完全阻止了,因此这里dead是完全的意思.故选D.65.C推理判断题.根据第五段第一句To become transparent an animal needs to keep its body from absorbing“sca ttering light.可知,想变透明就要避免散射或吸收光线,因此其中的一个方法是C选项,避免光线吸收.故选C.66.D,推理判断题.根据最后一段第一句中的make all the different tissues in their bodies slow down light exactly as much as water does可以推断出D为正确答案.其中slowdown对应reduce.故选D.【考点定位】科技类说明文【名师点睛】做科技类说明文时,考生应能:理解语篇主旨要义,理解文中具体信息,根据上下文提供的线索推测生词的词义,根据文中事实和线索作出简单的判断和推理。

Give them a limited time to read the whole passagein order to encourage them to practice reading for general ideas and todiscourage them from reading word by wordmain idea: This passage is a first-person account of a volcanologist’s experiences. The volcanologist described his exciting job and wrote down his first sight of an eruption.What does a volcanologist do ?( answer in the text )Then let students do the multiple-choices (见课件)2)Set Exercise 1 in “comprehending” either as a group or whole-class activity. Explain to students that the purpose of questions like these is to help them develop skills of evaluating a text.2.Second reading (intensive reading)Before reading, glance through Exercise 2 on Page35.Choose some to ask them and check their answers:1). Why is a volcanologist’s job import ant ?V olcanologists study volcanoes so that they can warn people when the volcano is going to erupt and so save many lives.2). Why is the lava that flows on Mount Kilauea more dangerous than the actualeruption ?The lava flows down the mountain and can cover up or burn villages in its path. the rocks that erupt from the volcano usually don’t damage anything because no one lives the crater.3). Why was it difficult for the writer to walk towards the edge of the crater ?The author was wearing special protective clothing that made it difficultto walk4). What does the writer find impressive about volcanoes even after studying them for 20 years ? The author is impressed by the beauty of the eruption and also by its potential to cause great destruction.3.Third reading (Read again to find more details)1).what made the author realize that an eruption occurred ?answer: my bed began shakinga strange soundmy bedroom became as bright as dayan abosolutely fantastic sightred hot lava was fountaining hundreds of metres into the air2).what did the scientists do after the eruption ?answer: put on white protective suits, helmets, big bootsdropped as closed as possible to the craterslowly make our way to the edge of the craterlooked down into the red boiling centerHomeworkSpend some time researching one disaster.

Life in the ClearTransparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch.Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless they’re eating it, or unless something is eating them.”And they are as clear as glass. How does an animal become see-through? It’s trickier than you might think.The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter(散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.But a transparent object doesn’t absorb or scatter light, at least not very much, Light can pass through it without bending o r stopping. That means a transparent object doesn’t look very different from the surrounding air or water. You don’t see it ----you see the things behind it.To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments(色素) that absorb specific colors of light. But a transparent animal doesn’t have pigments, so its tissues won’t absorb light. Ac cording to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.Animals are built of many different materials----skin, fat, and more----and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see—through. Others build a large, clear mass of non-living jelly-lie(果冻状的)material and spread themselves over it .Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they’re doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.63. According to Paragraph 1, transparent animals_______.A. stay in groupsB. can be easily damagedC. appear only in deep oceanD. are beautiful creatures64. The underlined word “dead” in Paragraph 3 means__________.A. silentlyB. graduallyC. regularlyD. completely65. One way for an animal to become transparent is to ________.A. change the direction of light travelB. gather materials to scatter light.C. avoid the absorption of lightD. grow bigger to stop light.66. The last paragraph tells us that larger transparent animals________.A. move more slowly in deep waterB. stay see-through even after deathC. produce more tissues for their survivalD. take effective action to reduce light spreading【解析】文章解释了生活在海洋的透明生物的特点,透明原理,以及形成机制.63.B细节理解题.文章第一段第三行:Most of them are extremely delicate and can be damaged by a simple touch.得知B选项:透明动物是很容易受伤的.故选B. 64D词义猜测题.该词出现在文章第三段第三行.前文提到了:你能看到的物体一种是对光线进行了散射,而另外一种是对光线的吸收.既然吸收了,那在光的传播过程中就完全阻止了,因此这里dead是完全的意思.故选D.65.C推理判断题.根据第五段第一句To become transparent an animal needs to keep its body from absorbing“scattering light.可知,想变透明就要避免散射或吸收光线,因此其中的一个方法是C选项,避免光线吸收.故选C.66.D,推理判断题.根据最后一段第一句中的make all the different tissues in their bodies slow down light exactly as much as water does可以推断出D为正确答案.其中slowdown对应reduce.故选D.【考点定位】科技类说明文【名师点睛】做科技类说明文时,考生应能:理解语篇主旨要义,理解文中具体信息,根据上下文提供的线索推测生词的词义,根据文中事实和线索作出简单的判断和推理。
