如:little, few, never, nothing, hardly等,其反意疑问句用肯定式(对于第四点大家不要忽视,尤其是列举的这几个词,出题的时候经常遇到,对于下面的两个例子大家要仔细看一下,要把这个知识点彻底搞懂)。 如:He knows little English, does he? They hardly understood it, did they?
5. 反意疑问句的陈述部分含有由un-, im-, in-, dis-, 等否定意义的前缀构成的词语时,陈述部分要视为肯定含义,问句部分用否定形式。如:Your father is unhappy, isn't he?The man is dishonest, isn't he?It is impossible to learn English without remembering more words, isn't it?

3. environmental protection 环境保护
10. avoid doing sth 避免做某事
1. made of 由……制(构)成,后接构成某物质的原料。例:This skirt is made of silk.这件裙子是用丝绸制成的。(1)be made of 表示制成成品后,仍可看出原材料是什么,保留原材料的质和形状,制作过程仅发生物理变化。例:The kite is made of paper.风筝是用纸做的。(2)be made from 表示制成的东西完全失去了原材料的外形或特征,或原材料在制作过程中发生化学变化,在成品中已无法辨认。例:The paper is made from wood.纸是木头做的。Butter is made from milk. 黄油是从牛奶中提炼出来的。(3)be made up of 用……构成或组成的,指人、物皆可,指结构成分。例:Our class is made up of six groups. 我们班是由六个小组组成的。
2. It seems that many people all over the world drink Chinese tea.句型“It seems that…”意为“看起来好像/似乎……”,其中seem是连系动词,意为“似乎;好像”,句型中的it是形式主语,不能用其他代词来替代。例:It seems that he was late for the train. 看来他没赶上火车。
(1)seem to do sth此句型可与“It seems that…”转换。例:They seem to find the way to the cinema. =It seems that they find the way to the cinema.例:My temperature seems (to be) all right. 我的体温看上去正常了。例:That seems not a bad idea. 看上去主意不错。
3. When the leaves are ready, they are picked by hand and then are sent for processing in factory.此句是由when 引导的时间状语从句,are picked, are sent都是一般现在时的被动结构。例:When the fruit are ready, they are picked and are sent to the market for sale.
4. No matter what you may buy, you might think those products were made in those countries.无论你买什么,你都可能认为那些产品是在那些国家生产的。此句为由"no matter +特殊疑问词"引导让步状语从句。意为“无论….”,相当于whatever。例:No matter what I said to her, she still didn’t believe me.
例:The police are trying to find out where the boy got off the train.find,find out和look for都含有“寻找、找到”的意思,但其含义和用法却不同。① find意为“找到、发现”,通常指找到或发现具体的东西,强调的是找的结果。Will you find mea pen? 你替我找支钢笔好吗? ② look for意为“寻找”,是有目的地找,强调“寻找”这一动作。例:I’m looking for my pen everywhere. 我正到处找我的钢笔。He is looking for his shoes. 他在找他的鞋子。③ find out意为“找出、发现、查明”,多指通过调查、寻问、打听、研究之后“搞清楚、弄明白”,通常含有“经过困难曲折”的含义,指找出较难找到的、无形的、抽象的东西。例:Please find out when the train leaves. 请查一下火车什么时候离站。
1. 时态:在英语语言中,时态主要讨论行为动词发生的时间。如:He often helps me with my English. 他经常帮助我学英语。(help这个动作经常发生often;故用一般现在时)
2. 语态:在英语语言中,语态主要讨论句子主语与行为动词的关系。语态有两种:主动语态和被动语态。如:The tall boy often hits his classmates (主语boy是谓语动词hit的发出者)。② 主语是动作的接受者(承受者)为被动语态。汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,而英语用:助动词be + 及物动词的过去分词构成如:Chinese is spoken by the most people in the world(主语Chinese是谓语动词speak的承受者)。
3. 语态与时态的关系:在任何一个英语句子中都同时存在语态和时态,他们是分析一个英语句子的两个主要元素。如:① He is looking after his sister at home. (此句为现在进行时的主动语态结构)② He is being looked after well by his parents. (此句为现在进行时的被动语态结构)
② 被动语态中的谓语动词必须是及物动词;因为被动句中的主语是动作的承受者,某些短语动词如look after, think of, take care of, work out, laugh at等,也可用于被动语态。
1. 当不知道或没有必要指出动作的执行者时,常用被动语态,这时往往不用by 短语。 Mr. White, the cup with mixture was broken after class. (只是告诉老师杯子坏了,不知是谁弄坏的,或不想说出谁弄坏的)。
2. 突出或强调动作的承受者,如果需要说出动作的执行者,用by 短语。如:The cup was broken by Paul.
2. 把主动语态的谓语变成被动语态的be + 过去分词,时态要与原句保持一致。3. 把主动语态的主语变为介词by的宾语,放在被动语态里谓语动词之后,by 短语可以省略。如果原句主语是地点名词,在被动语态中用in + 地点名词作状语。
五、一般现在时的被动语态:am /is/ are +done如:Tea is grown in Hangzhou. 杭州种植茶叶。
Unit6 When was it invented?
2. without doubt 毫无疑问的;的确
7. divide…into… 把……分成......
2. be used for doing 用来做…(是被动语态)(这个短语的考点有两点,一是used for的意思,二是for后面用动名词)Pens are used for writing. 笔是用来写的。
3. 给某人某样东西 give sth. to sb. I gave a pen to him. 我给他一支笔。 I gave him a pen. 我给他一支笔。
5. salty adj. 咸的 salt n. 盐
6. by mistake 错误地(犯错:make mistake,这些常见的短语大家务必要掌握)I took the umbrella by mistake. 我不小心拿错了雨伞。
I met her by accident at bus stop.
I didn't go to bed until I finished my work. 我直到完成我的工作才去睡觉。
according to this article 根据这篇文章
12. leaf n. 叶子 复数形式 leaves
The leaf fell into the river. 叶子落入了河里。She fell down from her bike. 她从她自行车摔倒了。
15. quite 非常 adv. 与冠词a连用时,冠词a必须放在它的后面quite a beautiful girl 一个漂亮的女孩
17. pleased adj. 表示外部因素引起人发自内心的欣慰和愉快
pleasant adj. 愉快,高兴。指天气、时间、旅行令人高兴愉快
18. battery-operated adj. 电池控制的,是名词+动词的运动分词构成的合成形容词
19. in the sixth century 在第6世纪
21. more than == over 超过(相比较,more than更重要)more than 300 == over 300 超过300
22. including 包括,可以与名词和动名词连用Six people, including a baby, were hurt. 6个人包括一个小孩受伤了。
23. have been played 被上演 ,是现在完成时的被动语态,现在完成时的被动语态的结构:have/has been +过去分词。
He was born in Canada. 他在加拿大出生。
25. safety n. 安全 safe adj. 安全的
27. divide sth. into…,将…划分成...,通常指将一个整体分成几个对应相对的部分Let's divide ourselves into 4 groups. 让我们把我们自己划成4组。
28. since then 从那以后,常与完成时态连用
1. 被动语态表示句子的主语是谓语动词所表示的动作承受者。
被动语态中的be 是助动词,有人称、数和时态的变化。一般现在时的被动语态为:am/is/are+过去分词一般过去时的被动语态为:was/were+ 过去分词A lot of trees were planted here last year.
与情态动词连用的被动语态:情态动词+ be + 过去分词(关于被动语态,大家一定要熟悉,这个在中考的时候属于是必考内容,而且是重点内容)
