a reading room = a room which is used for reading 阅览室
②表示所修饰的人或物的动作或状态，在意思上接近一个定语从句，可以表示正在进行的动作，也可表示经常性动作或当时的状态。
developing countries = countries that are developing发展中国家
2 作定语的动词-ing形式如是一个短语，则应放在被修饰词的后面,做后置定语，相当于一个定语从句。
They lived in a house facing south.(=which is facing south) 他们住在一所朝南的房子里。
正在访问日本的那个男人是我的叔叔。

1、动词-ing形式作宾语补足语常放在宾语后面，表示一个正在进行的主动性的动作，强调一个过程或一种状态。
When we returned, we found a stranger standing in front of the house.
2、当主句转换为被动结构时, 原来作宾语补足语的动词-ing形式便转换为主语补足语。
They found the film very exciting. = The film is found very exciting.
3、能用-ing形式作宾语补足语的几类动词:
1) 表示感觉和心理状态的感官动词，（常见的有see, hear, feel, smell, find, notice, observe, look at, listen to等）+ sb + doing sth（作宾补）
I felt somebody standing behind me.
2) 表示指使意义的动词使役动词，（常见的有have, set, keep, get, catch, leave等）+sb/ sth + doing sth (作宾补）
We kept the fire burning all night long.我们让火整夜燃烧着。
I won‘t have you running about in the room. 我不允许你在房间里跑来跑去。
4、see, hear, feel, watch等动词之后用-ing形式和动词不定式作宾语补足语的区别：
We heard the telephone ring. We heard the telephone ringing.
Book 4 UNIT1 1.only+状语（副词、介词短语或从句）位于句首时，句子要部分倒装。 （把be动词/情态动词/助动词提前到主语前面） only+状语+助V+主语+其他 ① I realized that I was wrong only then. ?

高中英语黄金阅读(高一版) 习俗类 (1) In the US, people prefer waiting for a table to sitting with people they don’t know. This means a hostess may not seat a small group until a small table is available, even if a large one is. If you are sitting at a table with people you don’t know, it is impolite to light up a cigarette without asking if it will disturb them. At American restaurants and coffee shops you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill. Most cities and towns have no rules about opening and closing time for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day. Serving in restaurants is often large; too large for many people. If you can’t finish your meal but would like to enjoy the food later, ask your waitress or waiter for a “doggie bag”. It may have a picture of a dog on it, but everybody knows you’re taking the food for yourself. Supper and dinner are both words for the evening meal. Some people have “Sunday dinner”. This is an especially big noon meal. Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change. 1. Which statement is true? A. American people like sitting with people they don’t know. B. A hostess always seats a small group at a large table. C. American people never sit with people they don’t know. D. American people would not light a cigarette if the people who sit at the same table mind their smoking. 2. What is served before you order? A. bread B. butter C. coffee D. cold water 3. What do American people always do when servings are too large for them? A. They take the food home with a doggie bag for their dogs. B. They leave the food on the table and go away. C. They take the food home with a doggie bag and enjoy the food later. D. They ask the waitress or waiter to keep the food for them. 4. Sunday dinner is_______. A. a dinner in the evening B. A big noon meal C. a big lunch on Sunday D. A supper on Sunday 【答案解析】本文介绍了美国人在外就餐时的风俗习惯。 1. D。细节题。根据第一段及关键句…it is impolite to light up a cigarette without asking if it will disturb them 可知 A、B、C 与原文不相符，同时关键句告诉我们“未

But he became inspired when he tho ught about helping ordinary people exposed to cholera. This was the deadly dise ase of its day. Neither its cause nor its cure was understood. So many thousand s of terrified people died every time there was an outbreak. John Snow wanted t o face the challenge and solve this problem. He knew that cholera would never b e controlled until its cause was found. He became interested in two theories that possibly explained how cholera ki lled people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person die d. John Snow suspected that the second theory was correct but he needed eviden ce. So when another outbreak hit London in 1854, he was ready to begin his enqu iry. As the disease spread quickly through poor neighbourhoods, he began to gat her information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why. First he marked on a map the exact places where all the dead people had liv ed. This gave him a valuable clue about the cause of the disease. Many of the d eaths were near the water pump in Broad Street (especially numbers 16, 37, 38 a nd 40). He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths. He had not foreseen this, so he made further investigations. He discovered that these people worked in the pub at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump. It seemed that the water was to blame. Next, John Snow looked into the source of the water for these two streets. He found that it came from the river polluted by the dirty water from London. H e immediately told the astonished people in Broad Street to remove the handle f rom the pump so that it could not be used. Soon afterwards the disease slowed d own. He had shown that cholera was spread by germs and not in a cloud of gas. In another part of London, he found supporting evidence from two other deat hs that were linked to the Broad Street outbreak. A woman, who had moved away f rom Broad Street, liked the water from the pump so much that she had it deliver ed to her house every day. Both she and her daughter died of cholera after drin king the water. With this extra evidence John Snow was able to announce with ce rtainty that polluted water carried the virus.

新人教版高中英语课文译文 必修四 第一单元卓有成就的女性 Reading 非洲野生动物研究者 清晨5点45分，太阳刚从东非的贡贝国家公园的上空升起，我们一行人准备按照简研究黑猩猩的方法去森林里拜访它们。简研究这些黑猩猩家族已经很多年了，她帮助人们了解了黑猩猩跟人类的行为是多么的相似。我们当天的首相任务就是观察黑猩猩一家是如何醒来的。这意味着我们要返回前一天晚上我们离开时黑猩猩睡觉的大树旁。大家坐在树荫下等待着，这时候黑猩猩睡醒了，准备离开。然后这群黑猩猩向森林深处漫步而去，我们尾随其后。在大部分时间里，黑猩猩或互相喂食，或彼此擦身，这在它们的家族里是爱的表达方式。简预先提醒我们，到下午的时候我们就会又脏又累。她说对了，但是到了傍晚时分我们就觉得这一切都是值得的。我们看到黑猩猩妈妈跟她的幼子们在树上玩耍，后来看见它们一起回窝里睡觉了。我们明白了黑猩猩家庭成员之间的联系像人类家庭一样紧密。 在简之前没有人完全了解黑猩猩的行为。她花了多年的时间来观察并记录黑猩猩的日常活动。从孩提时代起，简就想在动物生活的环境中研究它们。但是，这不是一件简单的事。当她1960年最初来到贡贝时。对女性来说，住进大森林还是很稀罕的事情。她母亲头几个月来帮过她的忙，这才使她得以开始自己的计划。她的工作改变了人们对黑猩猩的看法。比方说，她的一个重要发现是黑猩猩猎食动物。而在此之前，人们一直认为黑猩猩只吃水果和坚果。她曾经亲眼看到
过一群黑猩猩捕杀一只猴子，然后把它吃掉。她还发现了黑猩猩是如何交流的，而她对黑猩猩身势语的研究帮助她勾勒出黑猩猩的社会体系。 40年来，简·古道尔一直在呼吁世人了解并尊重这些动物的生活。她主张应该让野生动物留在野外生活，而不是用于娱乐或公告。她还为黑猩猩建起了可以安全生活的专门的保护区，她的生活是忙忙碌碌的，然而，正如她所说的：“我一旦停下来，所有的一切就会涌上心头。我就会想起实验室的黑猩猩，太可怕了。每当我看着野生黑猩猩时，这个念头总是萦绕着我。我会对自己说：…难道它们不幸运吗？?然后我就想起了那些没有如何过错却被关在笼子里的小 黑猩猩。一旦你看到这些，你就永远不会忘记……。” 简已经得到了她想要得到的一切：在动物的栖息地工作：获得博士学位；还向世人证明女人和男人一样也能在森林里生活。她激励着人们为妇女们的成就而喝彩。 Using Language 为什么不继承她的事业？ 上学时我喜欢英语、生物和化学，但是我进大学该选哪门专业呢？直到有一天晚上坐在电脑旁研究中国的伟大女性时，我才有了答案。 很偶然地，我看到了一篇关于林稚巧大夫的文章。她是妇科专家，1901年生，1983年去世。林稚巧似乎一直都在为自己选择的事业而奔忙，去国外留学，写了很多书和文章。其中有一本书引起了我的注意。这是一本小书，介绍如何从妇女怀孕到护理婴儿的过程中降低死亡率，她提出了一些可以遵循的简单的做法，保持婴儿清洁和健康，让他们远离疾病。她为什么要写这些东西呢?林稚巧认为哪些妇女会需要这些忠告呢？我仔细地看了这篇文章，了解到那是为农村妇女写的。也许是她们在遇到紧急情况时找不到医生。

人教版高中英语必修五知识点详解 Units 1-2 1. doubt doubt是高考中的高频考查词汇。doubt可作动词和名词，是新课标重点词汇。其命题角度为：①作动词时， 若为肯定句，后跟宾语从句,通常用if/whether引导，若为否定句，则通常用that引导。 ②doubt作名词时，通常用于There is no doubt that ...(毫无疑问）结构。2010年高考对doubt的考查还将集中 在其后跟从句时连接词的选择上，也有可能将doubt与其他动词或名词放在一起进行词义辨析。 2. expose expose是新课标要求掌握的单词，应重点掌握它的义项及常见用法，特别是be exposed to 句式，其中to为介词，后跟名词、代词和动名词；同时注意exposed to作后置定语和用于句首作状语的用法。另外，being exposed to结构用动名词形式作主语也是重点和难点，极易考查。 预测2010年命题方向为exposed to 作状语和定语的用法。 3. absorb absorb是新课标重点单词，重点掌握其“吸收（液体，热）；吸收，理解（知识）”的词义及其be absorbed in(全神贯注于……)的用法，易考点为该短语位于句首作状语和作后置定语两点，考生应能掌握be absorbed by(为某事物所吸引)；还应联系be engaged in, be devoted to, be involved in和be lost in等常见重点近义短语。 4. apart from apart from是常见介词短语，意为“除……之外”，考生应熟练掌握近义的词和短语：except, besides, in addition (to), other than, except for, except that, except when等。预测2010年高考会在单项填空题中直接考查或者会出现 在阅读理解题中。 5. available available是新课标重点单词，在近几年高考和各地的模拟考试中出现的频率极高，主要考点为：①词义(可得到的，可用的)。命题形式常为形容词词义辨析，如区分accessible, acceptable, sensible, favourite, average, convenient 等。②用法。be available to意为“可利用的”，be available for意为“使……可以享受某物;使……买得起某物”, 要了解二者的区别。 预测2010年高考命题会以考查词义或者形容词短语作后置定语为命题方向。 6. consist of consist of是近几年高考高频考查短语。①理解其词义“组成，构成”。②考查与其他近义词组的用法异同点。 如be made up of, be composed of, constitute, be formed of 等。考生要特别注意consist of要用主动形式表达， 不用系表结构。预测这一考点将成为2010年高考考查的重点，特别是用consisting of 作后置定语。 7. break down 由break构成的动词短语是历年高考命题的重点。考生必须明确break down的几个常见义项，根据不同的语 境加以判断。break down，break up, break off, break away, break in等，都要求考生熟知它们的常见义项，因为 命题时可能会对该短语直接考查，也可在短文中考查对其意义的理解。 8. only+状语（状语从句）位于句首构成部分倒装 这是考生必须熟练掌握的句式之一，以往的高考题中已多次考查到。倒装句式有多种情况，该句式为日常交 际中较常见的一种。特别提示：only只有强调状语或者状语从句才构成部分倒装，强调主语或宾语不用倒装。 预测该句式是2010年高考命题考查的重点。 重要词汇拓展 Unit 1 Great scientists 1. ____ n. 特征；特性 2. _____ vt.&vi. 结束；推断出→______ n. 结论 3. _____ vt. 打败；战胜；使受挫 4. ______ vt. 参加；出席；照顾；护理→_____ n. 参加；出席；侍从；看护 5. _____ vt. 暴露；揭露；使曝光→_____ n. 暴露；揭穿；揭发 6. _____ vt.& n. 治愈；痊愈→______adj.可治愈的 ______ vt.& n. 控制；支配 8. _____ vt. 吸收；吸引；使专心→______adj. 被吸收的；全神贯注的 9. _____ adj. 严重的；严厉的；剧烈的 characteristic 2. conclude；conclusion 3. defeat 4. attend；attendance 5. expose；exposure 6. cure；curable 7. control 8. absorb；absorbed 9. severe 10. _____ vt. 宣布；通告→______n. 宣布；宣告；通知 11. ______ vt. 命令；指示；教导→_____ adj.有教育意义的；有指导意义的→_____n.指导；指示；指令→_____ n. 教师；讲师；指导员 12. _____ vt.&vi. 捐献；贡献；捐助→______n.贡献；奉献 13. _____ adj. 有创造力的；创造性的；独创的→______n.创造；创作 14. _____ adj. 热情的；热心的→______ n. 热心；热情
