Not, especially. 你喜欢吃巧克力吗?不是特别喜欢。 （3）specially与 especially在数量、程度等方面表示“例外、格外、过分”的意思时一般可以互换。口语中，一般用specially, 正式文件中多用especially，特别是在介词或者连词前面尤为多见。例如：Its not specially/especially hot today.今天不算特别热。2 question, problem, trouble, matter的区别：这四个名词都可以翻译成“问题”，question指主观存在的“疑惑、疑问”，所以是需要“回答（answer）的”；problem指客观存在的和遇到的疑难问题，有时指较严重的问题，所以是需要“解决（solve，work out）的”；trouble指遇到的“麻烦、问题”，指存在并有点棘手的问题；matter表示“事情，麻烦”，指具有某种特征的事例。例如：You havent answered my question. 你还没有回答我的问题。His honesty is beyond question. 他的诚实无可怀疑。a key problem： 一个关键问题The problem was how to move the heavy machinery.问题是怎样移动这台沉重的机器。They are discussing how to solve the problem.他们正在讨论如何解决这个问题。The boy caused a lot of trouble to his parents；he was always in trouble.这个男孩给他的父母招来很多麻烦，他甚为苦恼。Students growing up from nursery school to college have trouble dealing with realities.从幼儿园到大学的大学生在如何应付现实生活上都存在困难。Trouble seems to be developing both in the cities and in the villages.城市和农村好象都在酝酿着麻烦的事端。This is a matter of no account. 这是一件无关紧要的事。I cant see the visitors right now. I have an urgent matter to attend to.现在我不能接见客人,因为我有一件急事要办。It is still a serious matter that some people drive after having drunk.一些人酒后驾车仍然是一个严重的问题。3besides, except, except for 与but的区别：这四个介词或者短语都可以表示“除了”的意思。但except仅表示“除了”，排除在外，后面可以接that，what，when等引导的从句；而besides表示“除了还有”的意思，表示包含在内；except for表示“除了”，它引出一个与前面的词相反的原因或者事例；but的意思与except接近，它主要与某些不定代词如nothing，all, anything， no one，anyone连用。例如：Except for one old lady, the bus was empty.公共汽车上要不是坐了一位老太太就是空的。She can do everything except cook.除了做饭之外她什么都会。He had considered everything except the weather.他什么都想过,唯独没考虑到天气。I know nothing about it except what I have read in the papers.除了在报上读到的以外,我对这件事一无所知。Most of the Chinese people usually go to work on the bike except when it rains.除了雨天,大多数中国人一般都骑自行车上班。Besides milk and cheese, we need vegetables.除了牛奶和干酪外，我们还需要蔬菜。Besides football, I like playing basketball and table tennis.除了足球以外，我还喜欢打篮球和乒乓球。No one but me passed the exam yesterday.昨天除了我以外没别人考及格。Nobody but Li Ming talked to Lao Wang today.除了李明，今天没有人给老王说话。三、重点句型1. I dont enjoy singing, nor do I like computers. 此句要注意的是表示否定意义的nor引导一个倒装句。 再如： I dont know how to play computer games, nor do I care. 我不知道怎样打电脑游戏，我也不在乎。 表示上一句的情况也适合下一句时，还可以用“so”表示肯定意义。例如：I work in a very big factory, so does he. 我在一个大工厂上班，他也是。2Despite the fact that they have never met each other, Michael and Xiao Li are best friends.此句中的that引导的是一个同位语从句，that在这类句子中不作成分。同样，that还可以在名词idea, plan, suggestion等词的后面引导同位语从句。再如：The idea that we go there by bus is acceptable because it is very far from here to the city.我们坐车去那里的想法是可以接受的，因为从这里到城里很远。3With so many people communicating in English every day, it will become more and more important to have a good knowledge of English.在英语中，with复合结构是一个常用结构，常用来作定语、状语等等。此句中的with复合结构作状语。再如：The poor girl, with a basket on her back, search all day from the foot of the mountain to the top of it.四、语法复习: 直接引语与间接引语：直接引语变为间接引语时，要从以下几个方面考虑：1句式的转变：当直接引语为陈述句时，间接引语变为由that引导的宾语从句。例如：“I like doing my homework in the evening,” said George.-George said that he liked doing his homework in the evening.当直接引语为一般疑问句时，就将其变为由if/whether引导的宾语从句,动词由say变为ask。例如：“Mary, have you seen Tom this morning?” Peter said to me.-Peter asked me whether/if I had seen Tom that morning.当直接引语为特殊疑问句时，就将其变为以这个特殊疑问词为连接词引导的宾语从句。例如：“What are they doing over there?” asked John.-John asked what they were doing over there.当直接引语为祈使句时，就将其变成动词不定式形式;同时还要注意把say改为可以接动词不定式作宾语补足语的动词，如tell, ask, order, advise等等。例如：“Go there at once,” Father said to me just now.-Father ordered me to go there at once just now.2人称的改变。变成间接引语的句子前后人称要一致。例如：“Your bike is more beautiful than mine.” she said to me.-She said that my bike was more beautiful than hers.3谓语动词时态的改变：当主句的谓语动词为一般现在时态时，从句可以根据需要使用不同的时态，也就是说，原来直接引语的时态大多不需要改变，而当主句用一般过去时态时，从句要用表示过去范畴的时态。例如：“Come here again next month,” he is saying to us.-He is telling us to come here again next month.注意：如果直接引语的谓语动词为一般现在时态，而内容又是客观事实、科学真理、现在的习惯动作以及格言等时，间接引语保持原来的时态不变。例如：The teacher said to us,” The earth goes around the sun.”-The teacher told us that the earth goes around the sun.4根据句子的意思，句中的指示代词、地点以及时间状语等也要作必要的变动。例如：“Come here,” the police officer said to the driver.-The police officer told the driver to go there.【考点透视 考例精析】考点 考查动词的-ing形式与-ed分词的用法。 考例1 The old man felt _ he couldnt say a word but cried with his body shaking at the airport.Aso excited that Bso exciting that Coo excited to Denough exciting to解析 选从对句子的结构分析我们可以看出这是一个复合句，因此用so that连接。Excited表示“某人对某事感到激动”，所以其主语多用指人的词；而exciting表示“某事令某人激动的”，因而主语多用指物的词。本句的意思是“那位老人感到非常激动，他在飞机场颤动着身体大哭起来，一句话都说不出来。”因此答案选A。考点 考查动词need to do与need doing/to be done的用法。考例2The teachers_ change their forms of practice, and sometimes some practice _ as well.Aneed, needs changing Bneed, needs to changeCneed to, need to change Dneed to, needs changing解析选由指人的词作主语，表示“需要做某事”的时候，应该使用句型“need to do something”；如果要表示“某事需要（被）做”，那就一般用指物的词作主语，使用句型“something need doing/to be done”。考点本题考查动词trade的用法以及not at all 与not a little的意义区别。考例3 Mr. Robert doesnt like to _ with Arabs _ just because he used to be hurt five years ago.Atrade, at all Bbusiness, not a bitCtrade, a little Ddo business, not a little解析 选“tradewith 与do business with”意思都是“与某人做买卖、交往”。Not at all 与not a bit都表示“一点也不”；但是，not a little表示“不止一点，非常，相当”的意思，相当于very的意思。所以，根据句子的意思，应该选A。拓展 not a bit与not a little这两个词组的意思要引起特别的重视，因为它们的肯定意思相同，而否定结构意思相差非常大。另外还要注意这两个词组的肯定式后面接名词时也是有区别的。a bit后要先接of再接名词；而a little后可以直接接名词。例如：There is only a little ink in the bottle.There is only a bit of ink in the bottle.考点 need作情态动词与作行为动词的区别。考例4 In fact you _ argue with anyone, just making yourself happy in your office. Aneed not to Bdidnt need to Cmustnt Dcant解析 选need既可以作情态动词也可以作行为动词。作为情态动词使用时，其后面直接接动词原形，否定的结构是直接在其后接not，而且无第三人称单数形式；用作行为动词时，变成否定句和疑问句要遵循其它行为动词的规则，即加上助动词do, does, did等等。【基础演练】一、根据所给首字母或括号中的汉语意思填写句子空格中所缺的单词。1You can spell the word “understand”, but can you p_ it? 2Pardon?

AKnow BKnowing CTo know DKnown【能力拓展】阅读理解： Many American presidents in the 19th century were born in poor families. They spent their childhood in little wooden rooms. They got little education. Washington and Lincoln, for example, never went to school and they taught themselves. Lincoln once did jobs for a worker, shop-keeper and post-master in his early years. A large number of American presidents had experiences in the army. The two best known were Ulysses Grant and Dwight D. Eisenhower. Grant was a general in the American Civil War and Eisenhower was hero in the Second World War. It happened that they graduated from the same school-West Point Military Academy(西点军校).One may be surprised to learn that both of them didnt do well in the school. Eisenhower, for example, was once fined(punished to pay money) because he broke the rules of the school. The jobs of the U.S. presidents are tiring. He must keep an eye on anything important that happens both at home and abroad. Every day, a lot of work waits for him to do and he has to make many important decisions. When Franklin Roosevelt
