第五单元如何写结论句
5．1结论句
第一单元曾提到，段落由三个部分组成，最后一部分就是结论句（ the
concluding sentence）。结论句通常与主题句一样包含有段落的中心思想，然而所用措辞与主题句不同。
在示范段落 1…1，主题句是： We all know that cigarette
smoking is a dangerous habit because it causes health problems．
结论句是： It is clearly identified as
one of the chief causes of death in our society．
5．2关于写结论句的建议
1）把握主题句的关键词
例如在关于“cigarette smoking”的示范段落 1…1中，中心思想是“the health problems caused
by cigarette smoking，关键词是“health problems”。
2）总结细节，回答主题句中隐含的问题。
在上述示范段落中，隐含的问题是“What are the health
problems caused by cigarette smoking？”结论句作出的回答是 It is identified as one of the chief cause of death in our society．
3）用不同的措辞表达同一中心思想。
在上述段落中，主题句的关键词是“health problems”，而在结论句中，关键词是“causes of death”。
示范段落5…1
Our neighborhood has been greatly changed． When I last visited there， about half the homes had been torn
down to make way for a superhighway． The remaining buildings were plastered with billboards and
surrounded by traffic signs and litter． Now the whole neighborhood has bee dirty， noisy and full of cars．
5．3示范段落分析
主题句： Our neighborhood has been
changed．
主题句关键词： changed
主题句隐含的问题：“How has the neighborhood
changed？
细节： 1． a superhighway built—noisy and full of cars
2． full of
billboards， traffic
signs and litter—dirty
结论句： Now the whole neighborhood has
bee dirty， noisy
andfull of cars．
结论句关键词： dirty，noisy and full of cars
结论句总结了细节并回答了主题句提出的问题。
Exercise 5…1
Directions：Read the following paragraph．Find out the topic sentence and the concluding sentence， and rearrange the details so that
the paragraph will make sense．
① In less than three years the farm
had gone to pieces．②All the windows had been broken out of the big two…story farm house．③In the front of the house the
grass was about three feet tall andthe barn yard was full of weeds instead of
pigs squealing to be fed．④There were no more cows to milk or horses to ride．⑤My grandmother's farm has a lot of
enjoyable memories for me，but after she died， I left home to join the army and when I returned，I was disappointed at the changes
that had taken place．⑥ Paint was peeling off the house and the porch roof was sagging．⑦ Lively as the place had been
before my grandmother died， it seemed to have died with her now．⑧This farm had once been lively with the noise of a tractor plowing
the land and a dog barking whenever someone came up to the house．

Exercise 5…2
Directions： Read the following paragraphs and underline the topic sentence of
each． Then write your
own concluding sentence to plete each paragraph．
（1）
Pollution has caused three major problems in the last decades．First， with the development of industry， more and more factories have been built and have sent out smoke and
poisonous gases．Thus the air
is polluted． The
increasing number of cars adds to the air pollution． Second， farmers use chemical fertilizers
to increase production and insecticide to kill insects． When rain flows with these
poisonous chemicals to rivers， water is polluted． A third formof pollution， noise， is being
more and more serious． Very loud noises can make people sick， and even drive them mad．

（2）
There are three important findings from studies concerned with
notetaking． First，notetaking does not interfere with
listening and prehension； in fact， it helps you listen． Second， students who study their lecture notes remember one and a half
times more after six weeks than students who do not review． Third， students who take no notes， or do not study their notes， forget approximately 80percent of
the lecture by the end of two weeks．From these findings we can conclude that students who take enough
notes and then study them， both directly after the lecture and several additional times before
an examination， stand a good
chance of remembering between90 and 100％ of the material！_______________________________________

第六单元 如何写好一个段落（Ⅰ）
6．1段落的特征
一个好的段落应该具有以下三个特征：1）完整性（pleteness）； 2）统一性（unity）； 3）连贯性（coherence）。
6．2完整性
段落的完整性指的是段落得以充分展开。作者一俟写好主题句，就应该用细节进行推展，细节越充足越好。例如，你认为“Riding motorcycles is dangerous”，你就应该用你所知道的事实证明这一观点是正确的。你可以使用数字（statistics），列举例子（example），进行描绘（descriptions）等等。
示范段落6…1
Ever since the time of the Greeks， drama has played an important role in man's lives． The Greek tragedies and e dies
were a central part of the citizens' lives in ancient Greece． During the Middle Ages， Bible stories were acted out in
churches，and wandering
panies of players performed in the streets． In modern times， drama is brought directly into people's homes through the magic of
television．
6．3示范段落分析
主题句： Ever since the time of the
Greeks， drama has
played animportant role in man's lives．
细节：1． ancient Greece
2． the Middle
Ages
3． modern times
作者根据各个不同历史时期提供细节，举例说明戏剧的重要性。
6．4 统一性
一个好的段落应该具有统一性。统一性就是一个中心思想统领整个段落。每个细节都应支持主题句，不应有无关的细节。为了支持主题，要尽可能多地提供细节，但又要避免滥用细节。
读下面段落，然后找出毛病。
① Innovations， whether practical or aesthetic， are often resisted by the general
population．② When the
early experiments in the field of aviation began their work， there were many who said，“If God had wanted man to fly， he would have given him wings．③The Wright brothers made the first
powered flights in a heavier…than…air craft in 1903 at Kitty Hawk， North Carolina．④Even today there are many who
strongly object to modern art and music as being nothing more than “splashes of paint and honking horns．”⑤The painter Picasso's well…known
masterpiece “The Three
Musicians” is done
primarily in blues and browns．
6．5段落分析
主题句： Innovations， whether practical or aesthetic， are often resisted by the general
population．
推展细节：1． People's objection to the early experiments in the field of
aviation．
2． People's
objection to modern art and music．
无关细节：1． The Wright brothers' experiment in flight．
2．Picasso's
painting．
显然这不是个好的段落，因为并非所有的推展句都支持主题句。应该把无关的细节删去。下图是一个有统一性的段落的结构图。
