Ⅰ.阅读理解(共15小题；每小题2分，满分30分)
A
The professor's house，big and untidy，stood alone at one end of a huge garden.The place was totally uncared for，quite wild and overgrown with all sorts of useless things.I fought my way to the front door and rang the bell.
I was glad that I had found him.In twenty minutes he put me right on all the points that had puzzled me.As I got ready to leave，I looked out of his study window and said，“You're very fond of gardening，I see.”
“No，I'm not，”he said.“But even so，I love this garden.It's as I always wanted it to be.I never touch it at all.”
“It could be made lovely.It seems a pity to let all this ground go to waste.But perhaps you don't see it that way？”
“I don't.I lived here when I was a child，and I had more than enough of gardening then.It was my father's hobby，you see.Unfortunately，he wasn't fit enough to do it himself.My brother and I did all of it between us with a spade(铁锹)and a fork year after year.There was one right way and many wrong ways.Each blade(flat，long leaf)of life was an enemy to be rooted out by hand，not just cut off.I've spent a good part of life at work here.”
“I see.You took a dislike to it，and now you're getting even！”
“I disliked it.Then，of course，I didn't understand the effect it had.It used to worry me.It appeared in my dreams a mistake here，something not quite straight there，the enemy showing its head in a place I was supposed to have cleaned.The work was too much.It seemed endless.The size of taking the place was itself a fight to a boy.
“And now it's yours.You're just letting it go to...”
“Ruin？”he said.“No，I don't agree with that.This garden and I are now the best friends.I like watching it grow in its own way.I make no demands on it.I never interfere with(干扰)it，and it never interferes with me.It has freedom at last，and so have I．”
“But the path is overgrown，It's inconvenient for you，isn't it？”
“That's part of my pleasure，”he laughed.“You can go out the back way.The weeds are shorter there because they don't get the sun.”
【语篇解读】本文是一篇记叙文。叙述了作者去教授家请教问题时，由教授家的花园而引出的话题。

A．He liked his father's wild，overgrown garden.
B．He was glad to be able to help his sick father.
C．He was beginning to like it.
D．He just hated it.
【解析】细节理解题。由文中第七段首句“I disliked it.”可推测。因为教授的父亲让他们兄弟两个每年都整理花园。那工作太多了，而且无休无止。
【答案】 D
2．Which of the following is TRUE according to the passage?
A．The professor usually went through the garden.
B．The writer thought of taking the path as part of his pleasure.
C．The professor's father was fond of gardening.
D．The writer and the professor talked about gardening for twenty minutes.
【解析】细节理解题。由第五段中“It was my father's hobby...”可知。
【答案】 C
3．In what way did the garden have “fr eedom”at last?
A．There was no gardener to control how it grew.
B．The chief way was through friendship with the professor.
C．The professor was free to do what he liked with the garden.
D．Only the front garden，where the sun shone，was free.
【解析】细节理解题。由倒数第三段中“I like watching...and so have I．”我喜欢它(花园)按自己的样子去生长。我对它没有什么要求。我不干扰它，它也不干扰我。它有了自由，我也有了自由可知，选A项。
【答案】 A
4．Why did the writer go to see the professor?
A．To ask for advice on gardening.
B．To seek solution to some problems.
C．To talk about the professor's childhood.
D．To find what a natural garden looked like.
【解析】细节理解题。由文中第二段第二句二十分钟内他就把使我感到迷惑的难点都
纠正了，可知作者是去向教授讨教问题。
【答案】 B
B
Without proper planning，tourism can cause problems.For example，too many tourists can crowd public places that are also enjoyed by the inhabitants of a country.If tourists create too much traffic，the inhabitants become annoyed and unhappy.They began to dislike tourists and to treat them impolitely.They forget how much tourism can help the country's economy.It is important to think about the people of a destination country and how tourism affects them.Tourism should help a country keep the customs and beauty that attract tourists.Tourism should also advance the wealth and happiness of local inhabitants.
Too much tourism can be a problem.If tourism grows too quickly，people must leave other jobs to work in the tourism industry.This means that other parts of the country's economy can suffer.
On the other hand，if there is not enough tourism，people can lose jobs.Business can also lose money.It costs a great deal of money to build large hotels，airports，air terminals，first-class roads，and other support facilities needed by tourist attractions.For example，a major international class tourism hotel can cost as much as 50 thousand dollars per room to build.If this room is not used most of the time，the owner of the hotel lose money.
Building a hotel is just a beginning.There must be many support facilities as well，including roads to get to the hotel，electricity，sewers to handle waste，and water.All of these support facilities cost money.If they are not used because there are not enough tourists，jobs and money are lost.
【语篇解读】这是一篇议论文。主要论述了发展旅游与保护当地居民权益之间会存在一些问题。
5．Which of the following do you think has been discussed in the part before this selection?
A．It is extremely important to develop tourism.
B．Building roads and hotel is essential.
C．Support facilities are highly necessary.
D．Planning is of great importance to tourism.
【解析】推理判断题。文章一开始就讲到了如果没有适当的计划，旅游业可能面临一些问题。与前文从正反两方面来论述。因此可以断定选文前的一段应该是从正面论述的。
【答案】 D
6．Too much tourism can cause all these problems EXCEPT________．
A．a bad effect on other industries
B．a change of tourists' customs
C．over-crowdedness of places of interest
D．pressure on traffic
【解析】细节理解题。文章提到了旅游业应促进旅游地当地人习俗的保持，暗含现在可能是改变或破坏了他们的习俗，但是并未提到会改变游客的习俗问题，因此正确答案为B 项。
【答案】 B
7．It can be inferred from the text that________．
A．the author doesn't like tourism developing so fast
B．local people will benefit from tourist attractions
C．other parts of a country's economy won't benefit from tourism much
D．we can't build too many support facilities
【解析】推理判断题。可利用排除法，也可直接根据“They forget how much tourism can help the country's economy，”一句推断得出结论。
【答案】 B
8．The author thinks it is good for local people to know that tourism will________．
A．waste a lot of money
B．weaken their economy
C．help establish their customs
D．help improve their life
【解析】推理判断题。由全文可知，A、B、C三项明显不符合旅游业的好处，也违背了常理，因此正确答案为D项。
【答案】 D
C
Londoners are great readers.They buy vast numbers of newspapers and magazines and of books－especially paperbacks，which are still comparatively cheap in spite of ever-increasing rises in the costs of printing.They still continue to buy “proper”books，too，printed on good paper and bound(装订)between hard covers.
There are many streets in London containing shops which specialize in book-selling.Perhaps the best known of these is Charring Cross Road in the very heart
of London.Here bookshops of all sorts and sizes are to be found，from the celebrated one which boasts of being “the biggest bookshop in the world”to the tiny，dusty little places which seem to have been left over from Dickens' time.Some of these shops stock，or will obtain，any kind of books，but many of them specialize in second -hand books，in art books，in foreign books，in books on philosophy，politics or any other of the countless subjects about which books may be written.One shop in this area specializes only in books about ballet!
Although it may be the most convenient place for Londoners to buy books，Charring Cross Road is not the cheapest.For the really cheap second-hand books，the collector must venture_off_the_beaten_track，to Farringdon Road，for example，in the East Central district of London.Here there is nothing so impressive as bookshops.The booksellers come along each morning and pour out their sacks of books onto small handcarts.And the collectors，some professionals and some amateurs，have been waiting for them.In places like this they can still，occasionally，pick up for a few pence an old one that may be worth many pounds.
【语篇解读】本文主要讲述了伦敦的书店，从出名的书店到街边小推车书摊等。
9．“Londoners are great readers.”means that________．
A．Londoners are great because they read a lot
B．there are a great number of readers in London
C．Londoners are readers who read only great books
D．Londoners read a lot
【解析】句意猜测题。由第一段可知，伦敦人买大量的报纸、杂志和书籍来阅读，故D项正确。
【答案】 D
10．According to this passage，Charring Cross Road________．
A．is in the suburbs of London
B．in famous for its bookshops
C．contains various kinds of shops
D．is the busiest street in London
【解析】细节理解题。由第二段的“There are many streets in London containing shops which specialize in book-selling.Perhaps the best known of these is Charring Cross Road in the very heart of London.”可知B项正确。
【答案】 B
11．In this passage，what does th e underlined part “venture off the beaten
track”mean?
A．Buy books in a most busy street.
B．Move away from a busy street.
C．Waste time looking for books.
D．Take a risk of losing one's life.
【解析】短语猜测题。由语境可知，要想买便宜的二手书就要离开这些方便的书店去伦敦东部，那儿有人把书放在推车上卖，也就是“从繁忙的街道到僻静的地方”，故B项正确。
【答案】 B
12．On Farringdon Road，________．
A．you can find fine bookshops for the latest books
B．there are only small bookshops for the secondhand books
C．you can see booksellers selling books on handcarts
D．the same books as the ones in the bookshops of Charring Cross Road are sold 【解析】细节理解题。由第三段的“The booksellers come along each morning and pour out their sacks of books onto small han dcarts.”可知C项正确。
【答案】 C

“In my opinion，”the first man said，“the Egyptian pyramids are the world's greatest wonder.Although they were built thousands of years ago，they are still standing.And remember：the people who built them had only simple tools.They did not have the kind of machinery that builders and engineers have today.”

If something that you're doing doesn't challenge you，then it doesn't change you.We all need some normal stress in our lives，after all.__16__So challenge the following limits：
1．Figure out what you're scared of and do it continuously.
If you're a salesman，and you're scared of talking to people personally or over the phone，now，instead of being scared and thinking you'll fail，spend at least five minutes a day to pick up the phone and make a call.__17__But don't stop on the first try！Eventually，you can look at fear in the eyes and say，“Go on，I'm not scared！”
2．__18__

__19__A simple 9-minute run around your neighborhood can do wonders for yourself.Exercise can not only help you maintain your regular weight，but also make you feel better about yourself.
4．Travel and allow yourself to be interested in new people.
Don't just limit yourself to your fellow travelers－try to connect with the service staff.You never know what kind of people they're going to be.Get out of your house or go online right now to book your class.__20__
A．You should do it continuously.
B．Someone may hang up on you.

Last Sunday ，I went sightseeing with my friends in the Fairy Lake Park.The park was full of beauty of spring ，with the sun shining and birds sing.When I was enjoying the fantastic scenery around ，something unpleasant caught their eyes.A young couple in a boat was eating ，talking and laughing loudly as if they were the only people in the world.Which was worse ，they spat and even threw rubbish into the lake ，total ignoring the noticeable sign “No Littering”nearby.What a shame!

So the woman took her trouble to the local magician. She told him her story, full of pity for herself. " Can you give me some magic powers to make him love me again? ” she asked anxiously. The magician thought for a moment and replied,“ I will help you, but first you must bring to me three hairs from a living lion. These! Must have before I can give you my magic powers.” There was indeed a lion that often came near to the village. It was frightening. The woman thought again and again and at last she had an idea. The next morning she took a young sheep and waited anxiously. When she saw the lion approaching, she left the sheep in the path of the lion quickly and went back home. So it happened that, every day early in the morning, the woman would rise and take a young sheep to the lion. Gradually the lion came to know the woman. Seeing the lion's trust in her, the woman carefully pulled three hairs from it and set out for the magicians house “Look, "she said happily as she entered, " here they are!
