There are some kinds of detectives who do not wear a uniform, like Hausman, solve endless mysteries every year. There is, for example, the dust detective. Tiny bits of dust stick to your clothes, your fingernails, your hair, or your shoes. They catch in your nose and in your ears. They tell where you have been and what you have done lately. The dust detective often helps catch a criminal by proving that he has been on the scene of the crime（罪案）.
Then there is the wood detective. By studying a piece of wood he can tell what kind of tree the piece of wood came from. He can tell where it was grown, and how old it is. He can even tell you what the weather was like at a certain place the year Columbus landed in America. The growth rings on a tree tell him.
64．According to the selection, by studying a piece of wood, a wood detective can tell you________.
A．what the weather was like the year Columbus landed in America.
B．what the weather was like last year in the mountain
C．what the weather was like last month in your hometown
D．what kind of tree the piece of wood came from
65．What does the underlined word “they”(para. 1) mean?
A．Your clothes           B．Your finger-nail
C．Tiny bits of dust        D．Your shoes

    Directions: Reading the following passage. Answer the questions accroding to the information given in the passage and the required words limit.
Xu Hui is very excited. The Senior 1 student in a middle school in Beijing will go to Japan with his parents during the Spring Festival.
“Overseas touring has always been a dream for me,” he said happily.
Nowadays, Chinese people enjoy longer holidays, such as the three “Golden Week Holidays”(the Spring Festival, May Day and National Day). They have more time to travel. Rising incomes also make travelling abroad realistic for ordinary Chinese people.
Nearly 7 million Chinese travelled overseas in 2001, according to the National Tourism Administration(國家旅游局). The most common problem travellers face is how to choose the best routes.
By the end of 2002, Chinese citizens were allowed to travel to 19 foreign countries and regions at their own expense.
The top 10 places included Hong Kong, Macao and Thailand. European countries are also becoming increasingly popular.
“More and more Chinese people have shown interest in travelling to Europe, particularly France and Finland,” said Tan Wen, a general manager of China Youth Travel Service. “Sooner or later, there will be a peak in European tours.”
Another consideration is choosing the right travel agencies and finding the best price. The China Consumers’ Association offered tips to consumers on choosing the right travel agencies to help prevent a relaxing vacation from turning into a costly disaster.
“Price should not be the single most important factor in choosing a travel agency,” said Zhang Yuanchao, CCA vice-secretary general. Consumers are advised to choose large State travel agencies with good reputations and official approval to organize overseas tour groups.
Zhang’s association dealt with more than 5, 000 complaints about travel agencies last year. And the majority of the complaints were about random changes in travel routes, bad tour guides, and forced shopping.
Travellers were warned to look carefully at their contracts with agencies and to buy travel insurance.
81. How many reasons are given in the article as to why ordinary Chinese people are traveling abroad more today? ( No more than 2 words )
82. List two factors Chinese travellers should consider while choosing a travel agency.
( No more than 3 words )
83. What seems to be the most common result of choosing a bad travel agency ?
( No more than 12 words )
84. What would be a good title for this passage ? ( No more than 6 words)

The tradition of birthday parties started a long time ago. There are some traditions that you can find almost anywhere, anytime, such as sending birthday cards, blowing out the candles on a birthday cake and singing the ‘Happy Birthday’ song. Others are only found for certain ages and in certain countries.
In China, on a child’s second birthday, family members put many things on the floor around the child. According to Chinese tradition, the first thing that the child picks up tells you what profession the child will choose later in life.
For Japanese children, the third, fifth and seventh birthdays are especially important. At this age, there is a special celebration Shichi-Go-San (seven, five, three in Japanese) when children go to the temple wearing a new kimono (和服). The priest (僧侶) gives them special sweets, and the parents usually organize a party for their friends in their home.
In Argentina, Mexico and several other Latin American countries, girls have a special birthday celebration when they reach the age of fifteen. After a special ceremony (儀式), the girls dance a waltz with their father and other boys.
Eighteen is the traditional ‘coming of age’— the age when (in many countries) you have the right to vote, join the army and (in Britain) drink alcohol or buy a house.
In many English-speaking countries, a twenty-first birthday cake often has a key on top, or the cake itself is sometimes in the shape of a key. The key means that the young person is now old enough to leave and enter the family home at any time they want to!

SECTION C
Directions: Complete the following passage by filling in each blank with ONE word that best fits the context.
How much paper do you use every year? Probably you can’t answer this question quickly. In 1900,the world’s use of paper was about one kilogram  48  each person in a year. Now some countries use as  49 as 50 kilograms of paper for each person in a year. The amount of paper a country uses shows how far advanced the country is, some people say. It is difficult to say  50  this is true: different people mean different things  51  the word “advanced”. But countries like the United States, England and Sweden certainly use    52   paper than other countries.
Paper, like many other things that we use today, was first made in China. In Egypt and the West, paper was not very commonly used before   53  year 1400.The 54  wrote on papyrus; Europeans used parchment for many hundreds of years. Parchment was very strong ;   55  was made from the skin of a certain young animal. We have learnt some of the most important facts of European history from record that were kept on parchment.

  51  The goal here is to limit carbon dioxide and other green house gases, which are closely associated to the big problem of global-warming．
Strategy 1: Bring your own cup to Starbucks
You’ll get a 10 cent discount, and it’s one less paper cup to end up in a landfill．While you’re there, pick up some free bags of spent coffee grounds to use as  ‘‘green’’  fertilizer in your garden．
The payoff:   52 
Strategy2: Turn off your computer
When in standby mode, your PC is still using energy．  53 
The payoff: Turning off a monitor for 40 hours a week may only save $5 a month, but it reduces CO2 by 750 pounds

The payoff:   54 The amount of oil it would take to make just 14 plastic bags would run your car for one mile．
Strategy4: Use recycled paper in the bathroom

The payoff: If every household replaced one roll of toilet paper with a recycled one, 424000 trees would still be standing．Look for eco paper towels too．
Strategy5: Buy energy-efficient appliances（電器）

Chocolate is good for your heart, skin and brain．Usually, people think that chocolate is bad for their health．They describe chocolate as“something to die for”or say“death by chocolate”．Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of coca’s chemicals, which seem to prevent both cell damage and inflammation（炎癥）．
Better blood pressure
If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3．5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．
Muscle magic
Chocolate milk may help you recover after a hard workout（鍛煉）．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．
Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women’s skin was moister（滑潤的）and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．

We are not born doubting ourselves. We learn to do it. In fact, we are usually taught to doubt ourselves. We can learn some ways that allow us to become more accepting of ourselves. Following are two behaviors that might explain the reasons why you can’t move towards greater self-acceptance.
One thing that might cause you not to accept yourself is over-generalizing about something you've done that you don’t like．For example, if you fail a test you might generalize and say, “I’m really a stupid person.” When you do this you are making a statement about all of you all of the time and not just about this one situation at this time. Instead, you might decide that your grade on this test in this subject at this time was indeed poor, and then go on to decide what you want to do about your poor grade, if anything. Getting stuck in over-generalizing discourages you from taking steps that might allow you to do better on the next exam and to build an expectation of future failure.
Having standards that are impossibly high is a second way you can not accept yourself. It may not come as a surprise to you that most of us are more demanding of ourselves than we are of others. Somehow we can tolerate the fact that other people fail, that they aren’t always kind, that they’ve done things they aren’t proud of, but we have difficulty accepting those very human aspects of ourselves. The need to be perfect is another way to set yourself up for failure and enhance the feeling that you are not acceptable. We all make mistakes. Accepting less than perfection simply means recognizing the limitations natural in being born a human being. Learn to value who you are rather than who you could become. Wouldn’t it be overpowering if we always had to do what we imagine we could do? Nobody has the time and energy to do all of that. We must make choices about what we will pursue and do them the best we can under the circumstances, which aren’t always ideal, by the way.
60．Which of the following is true according to the passage?
A. We can feel that we are perfect when we set ourselves up for success.
B. We can tolerate the fact that we’ve done things we aren’t proud of.
C. Over-generalizing might encourage you to expect the future.
D. Over-generalizing might cause you not to accept yourself.
61．What is the author’s attitude according to the passage?
A. It’s necessary for people to be perfect.
B. It’s acceptable for people to be imperfect.
C. It’s strange for people to be born with limitation.
D. It’s possible for people to do what they imagine.
62．What has caused the lack of self-acceptance?
A. Tolerance and high-level.
B. Limitation and expectation.
C. Over-generalization and high-standard.
D. Extreme difficulty and complete failure.

Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.
After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn't wash her window. It really looks terrible.”
One bright morning I decided to clean my flat, including washing the window on the inside. Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!
Then it dawned on me. I had been criticizing her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?
Since then, whenever I wanted to judge someone, I asked myself first, “Am I looking at him through my own dirty window?”
Then I try to clean the window of my own world so that I may see the world about me more clearly.  
64.The writer couldn't see everything clearly through the window because _______ .
A．the woman's window was dirty    B．the writer's window was dirty

A．the woman was sitting by her window
B．the woman's window was clean
