Ⅱ.阅读理解
For a while, my neighborhood was taken over by an army of joggers (慢跑者). They were
there all the time: early mornings, noons, and evenings. There were little old ladies in gray
sweats, young couples in Adidas shoes, middleaged men with red faces. “Come on！” My friend
Alex encouraged me to join him as he jogged by my house every evening. “You'll feel great.”
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I
took up jogging seriously and gave it a good two months of my life, and not a day more. Based on
my experience, jogging is the most overvalued form of exercise around, and judging from the
number of the people who left our neighborhood jogging army, I'm not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet take a real pounding running
down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a
nationally famous jogger who died of a heart attack while jogging, and I had something else to
worry about. Jogging doesn't kill hundreds of people, but if you have any physical weaknesses,
jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other
for fortyfive minutes isn't my idea of fun. Jogging is also a lonely pastime. Some joggers say，“I
love being out there with just my thoughts.” Well, my thoughts began to bore me, and most
of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn't just the first week; it
was practically every day for two months. I never got past the pain level, and pain isn't fun. What
a cruel way to do it! So many other exercises, including walking, lead to almost the same results
painlessly, so why jog?
I don't jog any more, and I don't think I ever will. I'm walking two miles three times a week
at a fast pace, and that feels good. I bicycle to work when the weather is good. I'm getting exercise,
and I'm enjoying it at the same time. I could never say the same for jogging, and I've found a lot of
better ways to stay in shape.
1．From the first paragraph, we learn that in the writer's neighborhood ________.
A．jogging became very popular
B．people jogged only during the daytime
C．Alex organized an army of joggers
D．jogging provided a chance to get together
2．The underlined word “them” in Paragraph 3 most probably refers to ________.
A．heart attacks
B．back problems
C．famous joggers
D．physical weaknesses
3．What was the writer's attitude towards jogging in the beginning?
A．He felt it was worth a try.
B．He was very fond of it.
C．He was strongly against it.
D．He thought it must be painful.
4．Why did the writer give up jogging two months later?
A．He disliked doing exercise outside.
B．He found it neither healthy nor interesting.
C．He was afraid of having a heart attack.
D．He was worried about being left alone.
5．From the writer's experience, we can conclude that
________.
A．not everyone enjoys jogging
B．he is the only person who hates jogging
C．nothing other than jogging can help people keep fit
D．jogging makes people feel greater than any other sport
Ⅲ.任务型阅读
The health dangers of smoking have been well reported. For years, doctors have warned
that smoking can cause lung cancer. Studies also have linked smoking to several other kinds of
cancer, heart attacks and other diseases, lung diseases, and a number of other medical problems.
The repeated health warnings have had an effect. Thousands of people have stopped smoking. But
as many people have learned, stopping smoking can be very difficult.
A major problem apparently is the nicotine, a poisonous substance found in tobacco. Small
amounts of nicotine are released as tobacco is burned. And over many years of smoking, a
person's body becomes dependent on the substance. An attempt to stop smoking brings the
problems of nicotine withdrawal (脱瘾过程)．
American medical researchers have found that nicotine withdrawal causes people to become
angry very easily, aggressive, worried and unable to think sharply. Many people who have tried to
stop smoking would confirm those findings.
To help people give up smoking, some tobacco companies have proposed chewing tobacco,
or using snuff as safe substitutes (替代物). Snuff is a tobacco powder that usually is breathed in.
But many people put it between their gum and cheek.
A group of British scientists said recently that many lives could be saved by a major program
to get cigarette smokers to change to snuff. An American scientist, Allan Blum, disagreed. Dr.
Blum argued that snuff, put in the mouth, can cause gum disease, teeth problems and throat
problems that lead to cancer. Dr. Blum also warned against chewing tobacco as a substitute for
smoking. He said chewing tobacco can lead to cancer of the mouth, throat or digestive system.
Medical researchers say another possible substitute for smoking is a special nicotine chewing
gum. The gum is already sold in Europe and Canada. A report says research shows that the
chewing gum will increase the amount of nicotine in a person's blood. This helps satisfy some
people's desire for a cigarette. However, the report says, the chewing gum also leads to some
unpleasant side effects. And it may be dangerous for people with heart problems.
Two other American scientists say they have found that the most effective way to stop
smoking is to do it completely, suddenly, all at once. The report by Saul Shirtman and Dr. Murray
Jogbett says that by stopping all at once, the worst problems of nicotine withdrawal are over in
just a few days. But, they say, by continuing to smoke, even a little less each day, the problems of
withdrawal never end completely.

课下能力提升(七)
Ⅰ.1.解析：选 B may 表示征求对方的许可，will 表示征求许可时，往往与第二人称连
用，故选 B。
2．解析：选 D 句意：了解文化差异是很重要的，这些差异可能会引发一些问题。may
表示推测，意为“可能”。must 表示必要性或是很有把握的推测；dare 用作情态动词时表示
“敢，竟敢”；need 表示必要性，意为“需要，必须”。
3．解析：选 D 先确定问句为一般将来时，因为像 come, go, leave, start 等这类趋向动词
的进行时表示将来含义。答语是就将来的动作作出判断。must not“不准”，与句意不符，故
排除 A 项；cannot 不可分开写，排除 B 项；need not“不必”，与句意不符，排除 C 项；只
有 D 项“可能不，不一定”，正好与后面的 He likes driving his car.相吻合，故选 D 项。
4．解析：选 B shall 在陈述句中用于第二和第三人称时，可以表示警告、命令、允诺、
威胁等语气； might 表示可能性很小； should 表示“应该(义务性)”；would 表示意愿。由
此可知这里选 B 项表示允诺。
5．解析：选 C 句意：你最好还是告诉制造商，男性顾客可能不喜欢家具的图案设计。
might just as well 表示“最好还是”，由此推断后文语气不是很肯定，所以用 may。
6．解析：选 D 句意：尽管我的腿受伤了，我还是游回了河岸。表示过去有能力并成功
做成了某事用 be able to，不用 could。dare“敢”； have to“不得不”。
7．解析：选 A 考查情态动词。句意：“孩子，你上的哪个网站啊？”“噢，妈妈……我
非得告诉你我做的任何事吗？”must 表示“非得，偏偏，硬要”，符合语境。
8．解析：选 D 由答语可知，电脑死机了。后面应该表示“它拒绝工作”。can't 表示“不
可能，没有能力”；mustn't 表示“一定不要，禁止”；needn't 表示“没有必要”；won't 表示
“不肯，就不”。根据句意应该选 D 项。
9．解析：选 D 本题用 should 表示“竟然，居然”之意，符合句意“真奇怪，他们竟
然没向我们道别就走了”。
10．解析：选 D 首先 need 作为情态动词的时候没有过去式的变化；其次在不定式的省
略中，动词可以省略，但不定式符号不能省略。故本题的答案为 D 项。
Ⅱ.
1．解析：选 A 推理判断题。第一段中提到作者所在的街区到处都是形形色色的慢跑者，
由此可推断 A 项正确。B 项与本段第二句内容不符；后两项在文章中没有信息支持。
2．解析：选 D 词义猜测题。本句的前面提到如果你有任何的身体虚弱症状，慢跑都会
让它们显示出来，由此可推断此项正确。文章中没有提到作者患有心脏病，所以 A 项与句
中的 as they did with me 不符；B 项只是身体虚弱的一个方面的表现。
3．解析：选 A 推理判断题。根据第二段的第一句内容可知作者起初认为可以尝试一下
慢跑。
4．解析：选 B 推理判断题。结合第三段的第一句、最后一句和第四段的第一句可推知
此项正确。作者是深受慢跑之害后才决定放弃这种运动的，而且文章的后半部分提到作者喜
欢外出快走和骑自行车去上班，所以 A 项不正确；后两项在文章中没有信息支持。
5．解析：选 A 推理判断题。文章开头部分提到慢跑在作者所在的街区已经蔚然成风，
可作者尝试一段时间后不得不放弃，由此可推断并非每个人都喜欢慢跑。B 项过于绝对；作
者没有推崇慢跑的意思，因此后两项不恰当。
