2．动词ing形式作状语时，前面可以加上连词或介词，但
返回
[考题印证3] 3－1 Sarah pretended to be cheerful,
________ nothing about the argument.
A．says
C．to say
B．said
D．saying
解析：选 D 。考查非谓语动词。say 与其逻辑主语Sarah
构成主动关系，因此使用现在分词，作伴随状语，选择D。
3．湖中央有一岛屿把湖分成两部分，湖的东北部

Sun Moon Lake
①Sun Moon Lake is located in Nantou County, Taiwan Province.②Sun Moon Lake is the largest natural lake as well as the most wellknown scenic spot in Taiwan. ③Do you know how its name came into being？④In
Hale Waihona Puke 返回解析：选 A 。考查非谓语动词。 句意：中国又建了一些高 速公路，这使得人们从一个地方到另一个地方旅行更容易 了。making 是现在分词，在句中作结果状语。不定式表示 偶然性很强或意想不到的结果，所以C项不合题意。
返回
三、使用动词ing形式需注意的几个问题 1．动词ing形式作状语时，其逻辑主语必须与句子的 主语一致。如果不一致，必须用独立主格结构来表示， 也就是在分词前面加上它的逻辑主语。
返回
3．在英语中，有些表示说话人态度的分词结构已成为固定 用语，不遵循其逻辑主语与句子一致的原则。这些短语 常见的有： generally speaking 总的来说
judging from/by ...
speaking of
根据……判断
说到……
talking of
frankly speaking
＝ After he finished the work, he went out to meet his
friends. 完成工作后，他出去会朋友了。 如果强调两个动作同时发生，分词前可加when或while。
返回
Be careful when crossing the street. 过马路时一定要小心。 Don't mention this while talking to him. 与他交谈时不要提这件事。
火车遇上了大雪，因此造成了耽搁。
返回

返回
3－2 ________around the fire, the tourists
danced with the local people.
A．Gather
C．Gathering
B．To gather
D．To be gathering
解析：选 C 。考查非谓语动词。句意：旅游者和当地的居 民围着篝火一起跳舞。主语the tourists和动词gather 是逻辑 上的主动关系，故用现在分词短语作伴随状语，故C项正确。 返回
＝ Because he was ill, he was sent to hospital.
由于生病，他被送往医院。
返回
[考题印证2] Sit down, Emma. You will only make yourself more tired, ________on your feet. A．to keep B．keeping
返回
[考题印证1] Dina, ________ for months to find a job
as a waitress, finally took a position at a local advertising
agency. A．struggling C．having struggled B．struggled D．to struggle
C．having kept
D．to have kept
解析：选 B 。考查非谓语动词。keeping on your feet 表
示“站立”，在句中说明使你疲劳的原因。
返回
3．表伴随或方式 He sent me an email, hoping to get further information. ＝ He sent me an email, and (he) hoped to get further information. 他给我发了封电子邮件，希望得到更多的消息。
是分词短语和句子之间不能用并列连词(如but, and)， 因为并列连词连接的是两个并列成分，而分词短语只是 全句的一个状语部分。分词和主句之间可用逗号。 Having been told many times, but he still couldn't
understand it.(×)
Having been told many times, he still couldn't understand it.(√) 已给他讲了许多遍，但他还是不理解它。
there on time.
她被交通阻塞耽搁了，无法准时到达那里。
返回
二、动词ing形式作状语的种类
现在分词作状语时，表示的动作是主语动作的一部分，
用来修饰谓语动词，常表示动作发生的时间、原因、 条件、结果、方式、伴随、让步等情况，并可以转换 成相应的状语从句或并列句。
返回
1．表时间
Walking in the park, she saw an old friend. ＝ When she was walking in the park, she saw an old friend. 在公园散步时，她看到一个老朋友。 Having finished the work, he went out to meet his friends.
解析：选 C 。考查非谓语动词。struggle与Dina为主动关系， 可排除B项；由句子结构可知，此处应用现在分词作非限制 性定语，补充说明Dina的情况。因为struggle这一动作发生
在谓语动词took之前，故用现在分词的完成式。
返回
2．表原因
Having traveled to many places, he knows a lot. ＝ Since he has traveled to many places，he knows a lot. 到过很多的地方去旅游，他知道的很多。 Being ill, he was sent to hospital.

人教版高二英语选修6_Unit_5_The_power_of_nature_全单元教案
Unit 5 The power of nature1.教材分析本单元以The power of nature 为话题，旨在通过单元教学使学生了解火山爆发、地震、台风、洪水等自然现象，认识到自然的伟大力量，并会用所学词汇描述在经历自然灾害时的感受，思考人类应对自然灾害的态度和方法，提高自我保护意识。
1.1 Warming Up通过对火山爆发示意图的讨论激活学生了解与本单元话题相关的背景知识，而后通过讨论人类应对自然灾害的措施引发学生对本单元话题的思考，激发学生的求知欲，为随后进行的听、说、读、写打下基础。
1.2 Pre-reading通过回答问题测试自己是否适合作火山学家，让学生了解这一陌生职业，为阅读做好准备。
1.3 Reading部分一位火山学家以第一人称的形式讲述了自己的工作及第一次目睹火山爆发时的情景和心情，描写了人与自然的斗争与和谐相处的乐趣，使学生认识到火山是美丽的，但同时极具破坏力，而火山学家的工作可以减少由火山引发的损失。
1.4 Comprehending设计了两种题型：第一题要求学生在阅读后回答相关问题；第二题检测学生对文章细节的理解。
1.5 Learning about Language 分为词汇和语法两部分。

Reading 介绍了旅游胜地 The Lake of Heaven, 培养学生快速获取信息的能力。
Writing 与Reading 属于同一话题，要求根据所给信息写一篇介绍Hot springs的作文。
高中英语Unit5 The power of nature文章 火山类型人教版选修六
火山类型火山是多种多样的，根据它们的活动情况可以分为死火山、休眠火山和活火山三大类。
死火山，指史前曾发生过喷发，但有史以来一直未活动过的火山。
此类火山已丧失了活动能力。
有的火山仍保持着完整的火山形态，有的那么已遭受风化侵蚀，只剩下残缺不全的火山遗迹、我国某某某某火山群在方圆约50平方公里的X 围内，分布着2个孤立的火山锥，其中狼窝山火山锥高将近120米。
休眠火山，指有史以来曾经喷发过．但长期以来处于相对静止状态的火山。
此类火山都保存有完好的火山形态，仍具有火山活动能力，或尚不能断定其已丧失火山活动能力。
如我国白头山天池，曾于1597年和1792年两度喷发，在此之前还有多次活动。
目前虽然没有喷发活动，但从山坡上一些深不可测的喷气孔中不断喷出高温气体，可见该火山目前正处于休眠状态。
活火山，指现代尚在活动或周期性发生喷发活动的火山。
这类火山正处于活动的旺盛时期。
如爪吐岛上的梅拉皮火山，本世纪以来，平均间隔两二年就要持续喷发一个时期、我国近期火山活动以某某岛大屯火山群的主峰七星山最为有名。
大陆上，仅95年在某某昆仑某某段于田的卡尔达西火山群有过火山喷发记录。
火山喷发形成了一个平顶火山锥，锥顶海拔4900米，锥高145米，锥体底直径642米，锥顶直径175米，火山口深56米。
应该说明的是，这三种类型的火山之间没有严格的界限。
休眠火山可以复苏，死火山也可以“复活〞相互间并不是一成不变的。
过去一直认为意大利的维苏威火山是一个死火山，在火山脚下，人们建筑起许多的城镇，在火山坡上开辟了葡萄园，但在公元79年维苏威火山突然爆发，高温的火山喷发物袭占了毫无防备的庞贝和赫拉古农姆两座古城，两座城市及居民全部毁灭和丧生。
火山喷发时，气体、岩浆、固体等物质向外排出的出口叫做火山口。
一般来说，中心喷发每次只有一个火山口，但绝大多数火山都是多次喷发。
以后的喷发有些是从原来的火山口喷出，但更多的是在其侧喷发，从而形成新的火山口，被称做寄生火山口。
