for ...在焦急中等待……的几周。‎ ‎6make one’s way　前往；获得成功 ‎(回归课本P35)It was not easy to walk in these suits，but we slowly made our way to the edge of the crater and looked down into the red，boiling centre.‎

‎8．A great man shows his greatness________the way he treats little men.‎ A．under B．with C．on D．by 解析：选D。本题考查介词的用法。“借助某种方法和手段”‎ 常用by；而with强调使用具体工具。with this method搭配相当于by the way。‎ ‎9．—I think he is taking an active part in social work.‎ ‎—I agree with you________.‎ A．in a way B．on the way C．by the way D．in the way 解析：选A。in a way＝in one way“在某种程度上”。on the way在途中；by the way顺便说；in the way挡道；碍事。句意：我在某种程度上同意你所说的话。‎ ‎7vary from...to...　由……到……不等 ‎(回归课本P39)The land varies in height from 700 metres above sea level to over 2,000 metres and is home to a great diversity of rare plants and

解析：选D。句意：很明显男人和女人，富人和穷人在希望、目标、恐惧和欲望方面有很大的不同。vary between...and...由……到……的情况不等。alter更改；transfer转换；shift转移，替换。‎ 句型梳理 ‎1【教材原句】　 It is said that this boy，who had a great gift for languages and persuasion，is the father of the Manchu people.(P39)‎ 据说这个男孩就是满族人的祖先，他具有语言天赋和很强的说服力。‎ ‎【句法分析】　(1)It is said that...表示“据说……”的意思，实际上it为形式主语，that 引导的为主语从句。相当于people say that...的意思。该结构还可以改变成sb.is said to do...结构。‎ ‎(2)注意根据动词不定式和is ‎ said动作之间的时间关系，使用不定式的一般式、进行式或完成式。‎ ‎①John is said to be one of the best teachers in the school.‎ ‎＝It is said that John is one of the best teachers in the school.‎ 据说约翰是这个学校最好的老师之一。‎ ‎②He is said to have written a new book about workers.‎ ‎＝It is said that he has written a new book about workers.‎ 据说他写了一本有关工人的新书。‎ ‎[归纳拓展]‎ ‎③It was reported that more than 180

in cages in order to have the pleasure of setting them free.‎ A．is said to be buying B．is said to have bought C．had said to buy ‎ D．has said to have bought 解析：选B。本题考查动词不定式及时态的应用。因为say与主语(人)是动宾关系，所以应用被动语态；再由括号中的时间标志可知应用现在完成时。故选B。‎ ‎2【教材原句】　Having collected and evaluated the information，I help other scientists to predict where lava from the volcano will flow next and how fast.(P34)‎ 收集和评估了这些信息之后，我就帮助其他科学家来预测熔岩接着将往何处流去，流速是多少。‎ ‎【句法分析】　having collected and evaluated the information是现在分词的完成式在句中作状语，表明从句动作发生在主句动作之前。‎ ‎①Having answered the teacher’s questions，she sat down and felt much more relaxed.‎ 回答老师的问题后，她坐下来，感到轻松多了。‎ ‎②Having been separated from other continents for millions of years，Australia has many plants and animals not found anywhere else in the world.由于与其他的大洲分离了几百万年了，澳大利亚有许多在世界上其他地方都找不到的动植物。‎ ‎【温馨提示】　过去分词作状语同现在分词作状语时一样，其逻辑上的主语就是主句的主语，但所不同的是，过去分词与主语之间存在被动关系，但有时无被动意味，只是表示一种状态或动作的完成，而现在分词与主语之间存在着主动关系。‎ ‎③Given better attention，the flowers could have grown ‎ better.‎ 要是照看得好一点，这些花会长得更好。‎ ‎④Dressed in white，she looks really pretty.‎ 穿着白衣服，她看起来真美。‎ ‎⑤Seeing the photo，he couldn’t help thinking of his good old days.看到那张照片，他禁不住想起了美好的往昔。‎ ‎[即境活用]‎ ‎12．________in the queue for half an hour，the old man suddenly realized he had left the cheque in the car.‎ A．Waiting　　　　　　　B．To wait C．Having waited D．To have waited 解析：选C。本题考查非谓语动词。根据the old man与wait之间的关系，应该选择v.ing形式，再根据句意得知他是先“wait”后才“realize”。所以先发生的动作应该用完成式Having waited。‎ ‎13．________there for some time，Mr.Johnson knew the place quite well.‎ A．Having lived B．Living C．To live D．Lived 解析：选A。考查非谓语动词。Mr.Johnson与live之间构成逻辑上的主动关系，“先在那儿住一段时间”才能“很熟悉那个地方”，所以应用v.ing形式的完成式作状语。‎ ‎3【教材原句】　The other two climbed down into the crater to ‎ collect some lava for later study，but this being my first experience，I stayed at the top and watched them.(P35)‎ 另外两人攀下火山口去收集供日后研究用的岩浆，我是第一次经历这样的事，所以留在山顶上观察他们。‎ ‎【句法分析】　this being my first experience 是独立主格结构。‎ 独立主格结构的构成方法：‎ n．/pron.＋v.ing/ed/to do/n./adj./adv./prep.phrase。‎ 其中名词或代词起着逻辑主语的作用；另一部分表示状态、状况或动作。‎ 独立主格结构本身不是句子，但在语义上相当于一个句子。在句子中作状语，表示时间、原因、条件、伴随等。独立主格结构一般用逗号与主句分开。‎ ‎①The guide leading the way，we had no trouble getting out of the forest.向导领着路，我们毫不费劲地走出了森林。‎ ‎②Weather permitting，we will go on an outing to the beach tomorrow.如果天气允许的话，我们将在明天组织一次海滨旅游。‎ ‎③He left the office，tears in eyes.‎ 他眼里含着泪水离开了办公室。‎ ‎④He walked into the classroom，his head lowered.‎ 低着头，他走进教室。‎ ‎⑤There being no one else to turn to，I had to come to see you.我没有其他可以求助的人，只能来找你。‎ ‎14．The children went home from the grammar school，their lessons ________for the day.‎ A．finishing　　　　　　　　B．finished C．had finished D．were finished 解析：选B。本题考查名词的独立主格结构。名词短语their lessons和动词finish之间是被动完成关系，故用过去分词finished。‎ ‎[即境活用]‎ ‎15．The car burns more fuel，but ________all things into consideration，it’s still a good car.‎ A．taken B．having taken C．taking D．to take 解析：选C。独立成分作状语。注意有些分词短语的形式是固定的，不受上下文影响，因此被称为独立成分。句意：这辆汽车耗油量较大，但是综合整体情况来看，它仍不失为一部好车。‎ 作文指导 说明文 ‎【体裁导航】‎ 说明文，顾名思义，就是要说清、道明。可见，清晰的描述、不紊的条理、分明的层次和准确的用词，都是说明文最明显的特征。‎ 无论是文字叙述还是图表标识，只要无时间限制，说明文中一般都要用现在时态。‎

time and we may change jobs ‎ several times in our career.‎ ‎②More people will be able to work at home, doing less manual work but more learning and thinking, which will make our brains bigger and bodies smaller.③Besides, transportation will become cleaner, faster, cheaper and not so crowded.④There will be no need to worry about the environment being polluted while traveling, for new fuels and engines will be used.‎ At that time，⑤people will be using the Internet to shop and do business while stores will be more like entertainment parks.⑥People will live in green houses and keep in touch with each other by using advanced videophones which can also be used for shopping and banking.‎ ‎⑦Altogether, compared to the life we live today，the future life will be totally different. ⑧However, no matter what happens in the future, as long as we learn to accept change and appreciate what is new and different，we will be well prepared for whatever the future may have in store and enjoy a happier and healthier life.‎ 点评：‎ ‎①由复合结构“with＋宾语＋宾语补足语”引出话题，自然流畅。‎ ‎②此句准确得体地运用了非谓语动词作状语和非限制性定语从句。‎ ‎③使用过渡词besides，把话题自然引到“交通方式的变化”上。‎ ‎④准确使用There is no need to do...句型，且多处使用非谓语动词，如：to worry，being polluted，traveling。‎ ‎⑤使用while来衔接两个不同的未来变化；前一个分句用将来进行时使举例时语言更生动形象。‎ ‎⑥by引导的方式状语中包含有一个定语从句。‎ ‎⑦用altogether引出对上面两段的猜想的总结。‎ ‎⑧由转折词however衔接两个句子，使句意互相照应，文章连贯流畅。‎ ‎【类题尝试】‎

a reversal of the braindrain since 1978 across the country.___________________________________‎ ‎___________________________________________‎ ‎________________________________________________________________________.‎ One possible version：‎ There has been a reversal of the braindrain since 1978 across the country.Between 1978 and 2007, about 7,000 overseas Chinese ‎ returned to Shanghai after completing their studies abroad.They accounted for about 25% of all returnees nationwide.The year 2008 has witnessed a boom.The number of returnees came up to 15,000.By the end of 2009, a further 22,000 have returned to this city.‎ The reversal of the braindrain mainly arises from three facts.Firstly, our government values overseas Chinese scholars highly, encourages them to return home to start their own careers and has worked out a series of preferential policies.In Shanghai, the famous international city, they can enjoy a modern lifestyle.Secondly, China’s economy has been developing at a high speed, which provides them with a vast space of development.‎ Many returnees have achieved outstanding success in scientific research or in highlevel management.They are playing a more and more important role.Thirdly, the current global financial crisis leaves many overseas out of work or at the edge of being laid off.They feel more secure at home because the economy is more stable.‎ I hope that more overseas Chinese can head home.There is a bright future ahead of them. ‎
