但except for 有时也可代替 except,特别是在句首时,因为 except 是不能用于句首的。
【例1】They weren’t a particularly good team, but they refused to give in and ______ defeat.
A. accept B. accepted C. accepting D. have accepted
【分析】考生容易误认为accepted与refused并列,于是选B。其实,accept与give in并列,故答案为A。
【例2】Mother told Jim to watch the milk until it boiled and then ______ off the gas.
A. turn B. turning C. turned D. having turned
【分析】答案为A。turn off the gas与watch the milk until it boiled并列。
【例3】He just does what he pleases and never ______ about anyone else.
A. think B. thinks C. thinking D. thought
【分析】答案为B。thinks与前面的does为并列谓语,同用一般现在时。
【例4】I don’t know whether to stay in teaching or ______ another job.
A. trying getting B. to try to get C. trying to get D. try get
【分析】答案为B。to stay in teaching与to try to get another job为两个并列的选择成分,故同用不定式。另外要注意:try to do sth.表示“努力做某事”,try doing sth.表示“尝试做某事”。
二、强调句
【例1】It was in the small house ______ was built with stones by his father ______ he spent his childhood.
A. which; that B. that; which C. which; which D. that; where
【分析】答案为A。答对此题的关键是要弄清第二空必须填that,因为这是一个强调句,被强调部分为in thesmall house,which was built with stones by his father是修饰它的定语从句。
【例2】It was the boy ______ had been in prison ______ stole the money.
A. who; where B. that; how C. who; that D. that; which
【分析】答案为C。本句中的被强调部分是the boy,who had been in prison是修饰它的定语从句。
【例3】It was just in the room ______ he was born ______ he died.
A. where; which B. that; that C. where; that D. which; that
【分析】答案为C。本句中的被强调部分是in this room。where he was born为修饰the room的定语从句。
三、逗号的陷阱
【例1】 ______ is reported, the project was completed yesterday.
A. It B. As C. This D. What
【分析】考生往往忽略了句子中间的逗号而认为此题是主语从句,把It当作句子的形式主语,况且It is reported...也是一个常用句型,读起来也很有英语语感,于是想当然地选了A。而事实上,答案选错了,因为在主语从句中的连接词that不能省略。正确答案应该为B,构成一个As引导的非限制性定语从句。
【例2】The purpose of new technologies is to make life easier, ______ it more difficult.
A. not make B. not to make . not making D. do not make
【分析】有的考生一看到句子中的逗号就会想到此题是考查非谓语动词作状语的用法,于是将答案误选为C。其实,在此句中,逗号相当于连词and或but。not to make it more difficult与逗号前面的不定式to make it easier相并列,对其进行补充、说明,因此答案为B。(值得一提的是:不定式并列作表语时,若否定的不定式在前而肯定的不定式在后,一般须用but连接,而不用逗号。如:My dream is not to live on the earth but to live on the moon.)
【例3】There were a lot of people in the reading-room, most of ______ with their heads bent down overtheir books.
A. them B. whom C. that D. which
【分析】乍一看题干结构,考生可能认为这是考查非限制性定语从句,从而将答案误选为B。但事实上,逗号后面由于没有谓语动词,不是完整的句子,而是一个with复合结构,故答案为A。

BEIJINGThe National Peoples Congress (NPC), Chinas top legislature, concluded its annual session Wednesday morning.
“The session was successful, with the further accumulation of common understanding,clarification of goals and reinforcement of confidence,” said Wu Bangguo, chairman of the NPC Standing Committee, in a speech delivered at the sessions closing meeting.
The session resulted in a full representation of the will of the people and the main concepts oft he Communist Party of China (CPC), he said.
NPC deputies, with a strong sense of responsibility and commitment to their mission, exercised their duties as entrusted by the Constitution and law, he said.
At the session, the NPC adopted a number of important documents, including the governments work report, central budget and national economic and social development plan for 2012.
While deliberating the governments work report, deputies agreed that the country made progress in economic, political, cultural, social and environmental arenas in 2011, making for agood beginning for the 12th FiveYear Plan period (20112015), Wu said.
This year will be an important year for China, as the 18th CPC National Congress will be heldlater this year, Wu said.
The NPC will work for the steady growth and stability of the country as it welcomes the 18th CPCNational Congress, he said.
The NPC also adopted several decisions on deputy elections for the 12th NPC and methods fort he election of deputies to the 12th NPC from Hong Kong and Macao special administrative regions, as well as work reports for the NPC Standing Committee, the Supreme Peoples Court and the Supreme Peoples Procuratorate.
This year, the country will carry out elections for deputies to the next NPC using the same ratio for rural and urban areas for the first time, Wu said.
He pledged to ensure stable and orderly elections in line with relevant laws.
At the closing meeting, lawmakers adopted an amendment to the Criminal Procedure Law.
The revision embodies the constitutional principle of respecting and protecting human rights and is a key improvement to the current legal system of criminal prosecution and litigation, Wu said.
The NPC will work to educate the public about the revised law and prepare for its implementation, he said.
Since this year marks the last session of the 11th NPC, Wu said the NPC will learn from the experience gained in previous years and improve the quality of its work, he said.
Top CPC and state leaders Hu Jintao, Wen Jiabao, Jia Qinglin, Li Changchun, Xi Jinping, LiKeqiang, He Guoqiang and Zhou Yongkang attended the closing meeting.
Less than half of the free umbrellas taken by commuters on rainy days as part of a Shanghai Metro project have been returned, according to the citys transport agency.
Passengers have been able to borrow the“Umbrellas for Love”since 2008, with all 280 stations initially issued with a stock of 100.
However, as the city is enduring daily deluges, staff at some stations say their stocks have run dry.
At South Huangpi Road Station on Monday, a sign stated that all umbrellas had been loaned out. A passing service center worker said:“Nobody gives them back.”
An employee at Lujiabang Road station gave the same answer, saying they were waiting for anew batch to arrive.
“Due to public demand and the high rate at which the umbrellas disappear, we have had to distribute extra batches at least three times over the past few years,” said Fan Wenjun, a media officer at Shanghai Metro operation management center.
Data provided by the center showed that of the 88,000 umbrellas allocated to stations, less than half are still in circulation. The return rate was 47.5 percent for the entire metro network in February.
Passengers can borrow an umbrella after writing down their name and phone number at the service center. Usually passengers will be reminded to return the umbrellas within a week to where they were borrowed. Each umbrella is numbered and belongs to a specific station.
“But we dont require passengers to show their IDs or verify their contact information. These umbrellas are loaned out of love. We hope people can cooperate with us,” said a subway worker at Lujiabang Road Station.
A metro employee surnamed Fan at Peoples Square Station, the busiest in the city, estimated that at least half of passengers give false information, which they discover when they call to remind them to return the umbrella.
China Daily talked to eight Shanghai residents. All said they would return the umbrellas.
分词是动词的一种非谓语形式,主要起形容词和副词的作用,可以作定语、表语或是状语等。分词有两种,一种是现在分词,一种是过去分词。这两种分词在句子中能担任的成分大体相同,主要是在“意思”上有主动和被动之分。过去分词一般有被动和完成两大特征。
过去分词的定语和表语功能定语表“完成”或“被动”
boiled water开水 fallen leaves落叶
the risen sun升起的太阳 selected apples 精选苹果
spoken English英语口语 iced beer冰镇啤酒
cooked food熟食 fried chips炸土豆条
单个的过去分词作定语时,一般放在被修饰词语之前(如上例),也可以放在所修饰词语的后面。 Hurry up,there is only a little time left.快点,时间不多了。
If you wish everything changed,please say so.
你如果希望改变一切,请说明。
过去分词短语作定语时,须将分词放在被修饰的词语之后,功能相当于一个定语从句。 Near the window,there is a bookshelf filled
with many books(=which is filled with many books).
靠近窗户,有一个装满书的书架。
Her daughter,brought up by me(=who was brought
up by me)has begun to work now.
由我带大的她的女儿现在已经参加工作了。 当“人”作主语时用过去分词作表语,表示主语的状态或思想感情等。 When we heard of it,we were deeply moved.
当我们听到这件事时,被深深地感动了。 He seemed quite delighted at the idea.
听到这个想法,他似乎很高兴。
过去分词作表语不要与被动语态混为一体。分词作表语表示主语的状态,而被动语态则表示被动的动作。 My glasses are broken.我的眼镜碎了。(状态)
My glasses were broken by my son.
我的眼镜被我儿子摔碎了。(动作)
On the earth,70% of the surface is covered with water.地球表面70%是被水覆盖的。(状态)

一、文字运用———逻辑思维
文字运用是语文能力中的基础能力,它是学生文字的书写、组合、选择等综合能力的体现,其考查的知识点通常以词语搭配、句式对应、病句修改、修辞运用等方式呈现。以2014年江苏高考语文试卷为例,在语言文字运用板块,分别考查了形容词与名词的搭配、成语的运用、诗句对仗的工整性、交际用语的得体性、语句排列的顺序性、看图配字的科学性等几个知识要点。对学生来讲,要掌握好文字运用这一技能,就应当关注、培养并不断提高逻辑思维能力。第一,基本词意理解。如“用心”与“匠心”, 前者多是指人对某种事物的投入度高,后者是指创造性的构思。在正确辨别之后,就不难做出正确的选择。这需要学生在复习中提高对词汇的意思、搭配、用法等方面的掌握。第二,生活常识鉴别。比如交际用语的选择,这需要学生加强对文明礼仪、礼貌用语、谦辞等方面知识的了解;比如对句式的排列选择,哪一种会更符合实际,哪一种更加自然等,这些都是学生生活常识的一个表现。第三,语意语感判断。比如选用哪一个更贴切、更符合人们的情感诉求等。总的来讲,在逻辑思维能力的培养与锻炼上,教师在复习时应当从点滴的细节入手,字、词、句、段落、文章这样由小到大,由浅至深地去挖掘知识要点。
二、现代文体———理解剖析
从2014年江苏高考语文试卷中的现代文阅读来看, 其考查的内容大部分是对文体内容的概括、对写作手法的运用理解、对作者思想精神以及文章中心的一个解读等,这些归纳起来都是对现代文体的一种理解与剖析。第一,最基本的内容概括。这是高考复习中最常复习到的一个知识要点,即如何正确地概括文章内容。一般来讲,教师既可以引导学生从每一段的概括到整篇文章的概括, 也可以引导学生通过抓住并围绕文章关键词的方法来概括。这一知识要点基本上可以在每篇文章中得到训练。第二,深层次的中心思想概括。与内容对比起来,中心思想已经上升到对作者的创作背景、所处时代、创作初衷、影响意义、精神状态、思想境界等方面的理解与剖析上;从方法论的角度上理解,教师可以引导学生根据文章的题目、关键词、开头结尾、中心句等加以理解与概括。这需要教师在复习课上教会学生如何去判断并捕捉关键词、如何从开头与结尾来推论作者的创作状态、如何从中心句 来反推假设作者的思想感情等。第三,对文章中某一部分进行重点理解。考虑到每一篇文章都会详略分布,为了更好地把握文章,就需要学生对详细部分进行扩大化理解,而这就是考查学生的细节理解能力。因此,教师在复习时,可以多引导学生关注细节,增强细节解读能力,以更好地提高对整个现代文体的理解与剖析能力。
三、文言文体———句式语意
与现代文体对比起来,文言文体的复习显得更有规律、更为具体,它考查的内容一般是对文言文词汇和句式的理解与用法,特别是与现代文体的差异等。以2014年江苏高考语文试卷中的文言文阅读为例,其中就包括对“益”“责”“攻”“爱”这四个词汇的理解,“其”的一词多义及一词多用;将“若乃名者,方为薄世笑骂,仆脆怯,尤不足当也”与“亟谋于知道者而考诸古,师不乏矣”这两句文言文翻译为现代语;以及对中心思想的解读这几种考查形式。这些都说明了高考语文对文言文体中关于句式、语意方面的要求。因此,为了更好地提高文言文的能力,教师在日常复习时应当抓住以下三个知识要点:第一,一词多用。特别是对于“其”“于”等介词,教师应当在复习高中所有文言文时进行梳理与归纳,并将同一词汇的多种用法以举例的方式各自成册,便于学生理解与吸收。第二,词语活用。特别是名词用作形容词、动词用作名词等灵活用法,教师可以鼓励学生自行进行归纳总结。第三,古今差异。这里指的是同一个词语或是句式, 在现代文与文言文中分别有不同的意思与用法,这也是高考经常考查的考点,它同样需要教师与学生在复习时进行归纳与梳理。
四、古诗文体———感情领悟
这里主要指的是诗词鉴赏,新课标也明确提及“应当培养学生在诗词歌赋等方面的欣赏能力”,而要实现这一目标,教师就应当鼓励学生“从心出发”,以感情领悟的方式去通达古诗文体。对比上文提到的文字运用、现代文体、文言文体而言,古诗文体的复习会显得较为抽象与可变,而为了培养学生对诗歌的感悟与领悟能力, 教师在复习时可以抓住以下两点:第一,题眼鉴别。如2014年江苏高考语文试卷中《休假日访王侍御不遇》中“不遇又空还”等句,它们往往是诗歌中的点睛之笔或浓缩之句,只要学生能够正确鉴别并捕捉,一般就不会偏离中心思想。第二,情感判断。如2014年江苏高考语文试卷中《休假日访王侍御不遇》与《访隐者不遇成二绝》,同样是“不遇”,但两首诗歌的感情却各不相同。要正确判断诗人的情感,教师在日常复习时可以多向学生介绍诗人的生平经历,特别是诗歌体裁上的情感偏向与内容选择等。一般高考所选取的诗歌都出自名家之手,都是学习中经常可以碰到的,只要学生了解并掌握了诗人的写作规律,就可以从共性出发来进行思考。
五、名篇诵读———重在积累
在高考语文复习中,名篇诵读是其中一个很重要的板块,如2014年江苏高考语文试卷中的名句名篇默写部分,基本上是学生必须掌握的章节,答题难度较低,只要学生熟练背诵了要求章节即可完成。但除了教材中对经典文章中的部分章节进行背诵外,教师还应当提醒并鼓励学生加强个人的积累,这既是为了更好地掌握知识的需要,也是培养学生语文素养的一种重要方式。为了最大限度地提高知识的积累量,教师应当利用好课前和课后的几分钟,还有教室正面黑板与背面的黑板报等。教师可以在每节课上课前与学生分享一句话或一小段名篇,在黑板或其他可利用的地方书写经典名言警句等。与此同时,还可以鼓励学生之间进行交流,或是在课堂上或是在其他地方与同学进行分享。总的来讲,在名篇诵读这一板块复习上,教师应当以潜移默化、积少成多、集腋成裘的方式来帮助学生拓展眼界,以更好地提高个人的知识储备量。需要注意的是,教师在推荐的同时应告知学生其基本意思、用法出处等,避免学生机械地背诵。
一、三角函数的定理
三角函数的本质是任意角的集合与一个比值的集合变量之间的映射。在高考中,很多试题主要侧重考查课本上的基本知识,或是与例题或练习题相关的变形题,具体来说主要是三角函数的公式、定理、性质的推导等,这都要求学生必须先掌握课本上知识的精髓,在此基础上理解其内涵,抓住其特点,这样我们才能会应用,会解题,以不变应万变。
例1.(2011陕西卷理18)叙述并证明余弦定理。
解析:要想正确解答此试题,首先清楚余弦定理的内容,然后根据所学的知识进行解答。此题虽然难度不大,考查内容主要是余弦定理的叙述与推导,这也是高考考查的常规方向和考点,目的是引导考生回归课本,因此学生在复习时必须重视基础知识的学习和巩固,尤其是课本上一些重要和经典定理的推导过程等。
二、包含三角函数的求零点问题
另外需要注意的是,高考命题时更注重对學生能力的考查,显著增加了对学生所掌握知识的综合性和应用性的考查,往往会在知识的交汇点设计题型,三角函数知识的特点使其很容易于其他知识点相结合,对于这些变化,在日常学习和复习中应引起重视。
