表示动作发生的时间、原因、结果、方式、条件、伴随状况等等。

3) 分词的否定形式not 位于非谓语动词___ .

3. 动词的 ing 形式(现在分词)作状语必须满足一个条件: 现在分词的逻辑主语必须是句子

的主语。如果不是这样,那么就要在现在分词的前面加上它的逻辑主语,这样就变成了独立主格结构。(选讲)

1) When Tony was waiting for the bus, a bird fell on his head.

=___ , a bird fell on his head.

2) All the tickets had been sold out, so the fans went away disappointedly.

=___ _, the fans went away disappointedly.

3)He guided the blind man, and they walked slowly across the s treet.

=___ , they walked slowly across the street.

4)She looked at the photo silently, and her tears fell down her cheeks.

= She looked at the photo silently, ___ _.

4. 评论性状语: 有些惯用的 V-ing 短语在句中中可以没有逻辑上的主语而独立存在,它们往

往作为句子的独立成分来修饰全句,表面说话者的态度观点等。我们称这种状语为评论性状语或评注性状语。

generally/ strictly/ narrowly speaking ….来说

judging from/ by 由...判断

considering taking everything into consideration/account 考虑到

人教版高中英语必修四(高一版)

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

新人教版高中英语必修四完整课文译文

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。

1.名词性从句在句子中起名词作用的句子叫名词从句(Noun Clauses)。名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。 一、引导名词性从句的连接词 引导名词性从句的连接词可分为三类: 连词:that(无任何词意) whether,if(均表示“是否”表明从句内容的不确定性) as if ,as though(均表示“好像”,“似乎”) 以上在从句中均不充当任何成分 连接代词:what, whatever, who, whoever, whom, whose, which.whichever,whomever 连接副词:when, where, how, why 不可省略的连词: 1. 介词后的连词 2. 引导主语从句和同位语从句的连词不可省略。 That she was chosen made us very happy. We heard the news that our team had won. 比较: whether与if 均为"是否"的意思。但在下列情况下,whether 不能被if 取代: 1. whether引导主语从句并在句首 2. 引导表语从句 3. whether从句作介词宾语 4. 从句后有"or not" Whether he will come is not clear. 大部分连接词引导的主语从句都可以置于句末,用it充当形式主语。 二. 主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that,whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导。that在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。 有时为避免句子头重脚轻,常用形式主语it代替主语从句作形式主语放于句首,而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下: (1)It + be + 名词+ that从句 (2)It + be + 形容词+ that从句 (3)It + be + 动词的过去分词+ that从句 (4)It + 不及物动词+ that 从句 另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should) +do”,常用的句型有: It is necessary (important, natural, strange, etc.) that … It is a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that…

人教版高中英语必修4课文原文Unit1--5

必修4 Unit 1 A STUDENT OF AFRICAN WILDLIFE It is 5:45 am and the sun is just rising over Gombe National Park in East Africa. Following Jane's way of studying chimps, our group are all going to visit them in the forest. Jane has studied these families of chimps for many years and helped people understand how much they behave like humans. Watching a family of chimps wake up is our first activity of the day. This means going back to the place where we left the family sleeping in a tree the night before. Everybody sits and waits in the shade of the trees while the family begins to wake up and move off. Then we follow as they wander into the forest. Most of the time, chimps either feed or clean each other as a way of showing love in their family. Jane warns us that our group is going to be very tired and dirty by the afternoon and she is right. However, the evening makes it all worthwhile. We watch the mother chimp and her babies play in the tree. Then we see them go to sleep together in their nest for the night. We realize that the bond between members of a chimp family is as strong as in a human family. Nobody before Jane fully understood chimp behaviour. She spent years observing and recording their daily activities. Since her childhood she had wanted to work with animals in their own environment. However, this was not easy. When she first arrived in Gombe in 1960, it was unusual for a woman to live in the forest. Only after her mother came to help her for the first few months was she allowed to begin her project. Her work changed the way people think about chimps. For example, one important thing she discovered was that chimps hunt and eat meat. Until then everyone had thought chimps ate only fruit and nuts. She actually observed chimps as a group hunting a monkey and then eating it. She also discovered how chimps communicate with each other, and her study of their body language helped her work out their social system. For forty years Jane Goodall has been outspoken about making the rest of the world understand and respect the life of these animals. She has argued that wild animals should be left in the wild and not used for entertainment or advertisements. She has helped to set up special places where they can live safely. She is leading a busy life but she says: "Once I stop, it all comes crowding in and I remember the chimps in laboratories. It's terrible. It affects me when I watch the wild chimps. I say to myself, 'Aren't they lucky?" And then I think about small chimps in cages
