Effects presuppose causes.
一种结果必然会有其原因。

这种药的副作用之一就是容易上瘾。
（2）常用短语：
①in effect：正在实行；实际上

②take effect：开始；实行；开始生效
The medicine quickly took effect. 药很快见效了。
The contract has taken effect since October 1. 本合同从十月一日起已经生效。
③to... effect：大意是…。注意：此处的to为介词，它与effect之间经常有一个表示程度的词。
例如：

④have effect(s) on/upon sb./sth.：对某人某物有影响。

例如：

含酒精的饮料会对你身体有很坏的影响。

（3）effect: 作为动词，它经常用作及物动词，意思是“实现”。

这位新部长希望改变政府的政策。

（3）指“有些；一些”。
例如：

People who smoke cannot travel in certain parts of the train.
吸烟的人不能在火车的某些地方走动。
二、词义辨析
1．effect, consequence, result的区别：
（1）这三个词作为名词在一起比较的一般含义是由某种原因所产生的结果。
effect 和原因的关系是立刻性的，即马上可以看到的
Jasper has put up “No Parking” signs outside his gate, but these have not had any effect.
贾斯珀“把禁止停车”的牌子挂在大门外，但这没产生什么效果。
The idea to have the capital moved so far inland will have a great effect on the future of Brazil.
把首都远迁内地的这一主张对巴西的未来将产生巨大的影响。
The drug has had an immediate effect on the patient.
此药对病人立刻产生了效果。
（2）consequence 和原因的关系没有那么紧密，并非马上可以可见。
You should be responsible for all the consequences.
你应当为这一切后果承担责任。
Do you know what the consequences of your action will be?
你知道你的行为将会产生什么后果吗？
The consequence was that he caught a bad cold.
结果是他得了重感冒。
（3）result 虽然和原因关系密切，却不是立即可见，而是最后才能显示出的。比方某人头部受到沉重的一击，马上产生的脑震荡(此为effect)。脑震荡后他的身体渐渐垮了(即consequence)，最后不能从事正常工作了(即result)
When the first radio messages have been received, the results of the trip will be announced immediately.
当收到第一批无线电信息时，这次太空之行的结果将立即公布出去。
His limp is the result of a car accident last year.
他的跛足是去年一次车祸所致的结果。
注：consequence 和result 都可以用复数形式，而effect 一般常用单数，有时也用复数形式表示“结果”。
2．Produce, product 与production的区别：
（1）produce: 主要作为动词使用，意思是“出产；生产；提出；拿出”等。有时也可以作名词使用，意思是“产物，产品”，多指农产品，为不可数名词。
to produce wheat：出产小麦
That factory produces cars. 那家工厂生产小汽车。
to produce one's ticket：出示票
Can you produce any proof of your nationality? 你能出示有关你国藉的任何证件吗?
The whisky bottle was marked 'Produce of Scotland'. 这瓶威士忌酒上标有'苏格兰出品'的字样。
（2）product意义较为广泛，也是最普通的表示“产品，产物”的词，它可以用来指天然的、人造的产品，也可以用来指农产品，还可以指脑力劳动的结果等。
例如：
Petrol is the most important product of many Middle-East countries.
石油是许多中东国家最重要的产品。
The company sells plastic products. 这家公司出售塑料制品。
Criminals are sometimes the product of less education. 犯罪有时是缺乏教育的结果。
（3）production：意思是“生产，产量”。指“生产”时侧重其行为，而指“产品”时，侧重“产量”，也可以指文学作品。
例如：
the production of wheat：小麦生产
The production of corn has increased. 玉米的产量已增加。
Production of computers has increased double in the last few weeks.
近几周来电脑的产量增加了一倍。
This new theatre is becoming known for its good productions.
这家新剧院因上演节目的质量好而渐渐出名。
This book on education is his latest production.
这本论述教育的书是他的最新作品。
三、重点句型:
1．What affects do you think the changes in eating habits will have on agricultural or nature?
此句中的do you think为插入语，句子的疑问语序由do you think来体现，所以其它成分就用陈述语序。
2．It is on this arable land that farmers produce food for the whole population of China.
此句为强调句型。句中的on this arable land为状语，是被强调的成分，值得注意的是其后的连接词只能用that，而不能用where；同样表示时间的状语被强调时，也只能用that， 不用when。
例如：
It was on the morning of last Monday that I met Dr Johnson on the bus. 我是在上个星期一的早上在公共汽车上遇到的约翰逊博士。
3．Not only is food production important but also taking care of the environment.
Not only…but also…连接的句子中，当not only置于句首时，其后的句子用倒装语序。此句中，but also后的句子为省略句。
再如：
Not only will we have classes in the hall, but also the students of Class 19.
不仅我们要在大厅里上课，19班的学生也会（在大厅里上课）。
4．The temperature is controlled with computers, no matter how the weather is outside.
注意此句中的no matter how引导的是让步状语从句。be controlled with中“with”为介词意思是“用”。
再如：
No matter what I said, they wouldn’t let me in. 无论我说什么，他们也不让我进去。
The movement of the ball is controlled with a stick. 那个球的动作是用一根操作棒进行的。
四、语法复习
-ing形式作定语和宾语补足语：
1．-ing形式作定语：
（1）表示被修饰的名词是分词的动作的发出者。可以放在被修饰的词前，叫做前置定语；也可以放在其后面，叫做后置定语。单个的或者仅仅带有一个副词的分词常作前置定语；而分词短语通常作后置定语。前置定语通常表示一种相对的持久性、一种特征，更象一个形容词；后置定语比较突出分词的动作。
例如：
the weeping girl （哭泣的女孩）
a boring speaker （令人厌倦的演讲者）
freely falling body (自由落体)
the boys playing in the garden（在花园里玩耍的男孩子们）
the man standing behind her（站在她身后的男子）
（2）-ing形式短语作定语时，常常表示一个与谓语动词的动作同时发生的动作。
例如：
Do you know the man speaking to my sister?
你认识和我姐姐说话的那个人吗？
The young man sitting in the third row is a famous doctor.
坐在第三排的那个年轻人是个著名的医生。
（3）-ing形式短语在特指的名词之后作定语时，通常只含有“正在进行”的意思。但当用在一个泛指的名词之后作定语时，可以表示“进行”的意思，也可以表示一般的情况。
例如：
The students working in the factory will go back to school next week. （特指，表示正在进行。）
正在工厂工作的那些学生下周将回学校。
Matter is anything having weight and occupying space. （泛指，表示一般情况。）
凡是物质，都具有重量，并占有空间。
（4）being所引导的-ing短语不能作定语，但是其被动语态“being + v-ed”可以。
例如：
The car being repaired there is our headmaster’s.
那辆正在修理的车是我们校长的。
In Europe there are very few wooden houses being built today.
在欧洲，目前很少有人在建木头房子了。
2．-ing形式作宾语补足语：强调动作的进行。只有几类动词可以用-ing形式作宾语补足语：
表示知觉的：see, watch, notice, observe, find, think, feel, hear, smell, listen to, look at
表示“使役”的：have, make, get等。
表示“愿望”的：want, wish, expect, like等。
表示“致使”的：set, keep, catch, leave等。
表示“认为”的：regard, accept, think等。
His remark left me wondering. 他的话让我惊讶。
I hope I haven’t kept you waiting too long. 我希望我没有让你久等。
I saw her walking alone. 我看到她独自走着。
【考点透视 考例精析】

[考例1] --Is it that Tom often plays computer games ________ makes his parents worry about him?
--Yes, I think so.
A．what B．that C．when D．which
[解析] Ｂ　考查强调句型以及定语从句的混合结构。被强调的部分是that引导的定语从句。而要选的that是强调句中的连接词。
[考点] 可数名词与不可数名词。
[考例2] He is a man with ________ of staying in France for 20 years.

[解析] Ｃ　experience表示“经验”时，为不可数名词；表示“经历”时为可数名词。本句中，“他是一个有…经历的人”，所以应为可数名词，前面加an。
[拓展] experience表示“经验”为不可数名词。例如：
Does he have much experience in teaching?
他教学经验丰富吗？
[考点] 疑问的强调句结构。
[考例3] Why! I have nothing to confess. __________ you want me to say?
A．What is it that B．What it is that
C．How is it that D．How it is that
[解析] Ａ　注意的是：有时被强调的部分是疑问词，这时，除了注意分析疑问词的作用外，还要注意其它成分的语序。
