C
The World Trade Organization came into existence in the 1990s. It operates a system of trade rules. It serves as a place for nations to settle disagreements and negotiate agreements to reduce trade barriers. The newest of its 150 members, Vietnam, joined in January.
But the roots of the W.T.O. date back to World War Two and the years that followed. In 1944,   the International Monetary(貨幣的) Conference agreed to create the International Monetary Fund and the World Bank. But they could not agree on an organization to deal with international trade.
Three years later, in 1947, twenty-three nations approved the General Agreement on Tariffs (關(guān)稅)and Trade, or GATT. It was meant to be temporary. Trade negotiations under GATT were carried out in a series of talks called rounds. The first round lowered import taxes on one-fifth of world trade. Later rounds produced additional cuts, and negotiators added more issues.
The sixth round began in 1963. It was called the Kennedy Round after the murder of President John F. Kennedy. The results included an agreement against trade dumping. This is when one country sells a product in another country at an unfairly low price.
The eighth round of talks began in Punta del Este, Uruguay, in 1986. The Uruguay Round lasted almost twice as long as planned. In all, 123 nations took part in seven-and-a-half years of work. They set time limits for future negotiations. They also agreed to create a permanent system to settle trade disagreements.
In April of 1994, most of those 123 nations signed an agreement. It replaced GATT with the World Trade Organization.
The W.T.O. launched a new round on development issues in Doha, Qatar, in November of 2001. These talks were supposed to end by January of 2005. But negotiators could not agree on issues involving agricultural protections. The current round has been suspended since last July.
66. The WTO got this name in the year _____.
A. 1947    B. 1963   C. 1986   D. 1994
67. Which of the following statements about GATT is NOT true?
A. It was set up after World War II.
B. It was first approved by less than 30 countries.
C. It was a branch of the World Bank.
D. It was meant to improve international trade.
68. What does the underlined sentence in the third paragraph mean?
A. The founders wanted GATT to bring in money.
B. The founders didn’t expect GATT to last long.
C. GATT was ready to change its name at the very beginning.
D. GATT was open for more member countries.
69. What is one of the results of the Uruguay Round?
A. A permanent system was agreed on.
B. It lasted almost eight years.
C. More countries took part in it.
D. More disagreements than expected were settled.
70. Which of the following is the best title of the passage?

Andy is the most unreasonable, pigheaded life form in the world, and he makes me so angry I could scream! Of course, I love him like a brother. I have to because he is my brother. More than that, he is my twin! That’s right. Andy and Amy(that’s me) have the same curly(卷曲的) hair and dark eyes and equally stubborn character. Yet, though we may look alike, on most issues(事情)  we usually take completely opposite positions. If I say day, you can count on Andy to say night.

Just this week, the hot topic in school was all about the PTA’S proposal(提議) to adopt a school dress principle. Every student would be required to wear a uniform. Uniforms! Can you imagine? Oh, they would be uniforms in color. The dress style would be sort of loose and free.

I think a dress principle is a good idea. The reason is simple. School is tough enough without worrying about looking cool every single day. The fact is, the less I have to decide first thing in the morning, the better. I also wouldn’t mind not having to see guys wearing oversized jeans and shirts. And I certainly would welcome not seeing kids showing off designer clothes.

Andy is surprised at my opinion. He says he can’t believe that I would be willing to give up my all-American teenage birthright by dressing like — well, like a typical teenager. Last night, he even dragged out Mom and Dad’s high school photo albums. What a couple of peace-loving hippies(嬉皮士) they were!

The vote for or against uniforms took place later that day. The results of the vote and the headmaster’s decision will be announced next week. I wonder what it will be. I know how I voted, and I’m pretty sure I know how Andy voted.

How would you vote—for or against?

1.The story is about___________.

A. a school policy decision that will affect parents and students

B. a personal experience and is told in the first person

C. a historical event and is told in the third person

D. a conflict of opinions between boys and girls

2.Amy’s position on school uniforms is most likely based on________.

A. logical conclusions drawn form her own observation and personal experience

B. an aggressive reaction to what she has been told by people in authority

C. her preference for designer-labeled clothes

D. not liking anything her brother likes

3.Which of the following is the best statement of Andy’s position?

A. School clothing should reflect parents’ values.

B. Teenagers should never follow the latest fashions in dress.

C. How one dresses should be an expression of one’s individuality.

D. Wearing school uniforms means one less decision every morning.

4.What is the best title for the text?

A. A School Dress Principle.

B. My Stubborn Twin Brother

C. Endless Fights with My Brother

D. For or Against?--- That Is the Question

四.任務(wù)型閱讀:

認(rèn)真閱讀下列短文,并根據(jù)所讀內(nèi)容在文章后表格中的空格里填入一個(gè)最恰當(dāng)?shù)膯卧~。

About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table, I couldn’t help overhearing parts of their conversation. At one point the woman asked,“So, how have you been?”And the boy—who could not have been more than seven or eight years old—replied. “Frankly, I’ve been feeling a little depressed lately.”

This incident stuck in my mind because it confirmed my growing belief that children are changing. As far as I can remember, my friends and I didn’t find out we were “depressed” until we were in high school.

The evidence of a change in children has increased steadily in recent years. Children don’t seem childlike anymore. Children speak more like adults, dress more like adults and behave more like adults than they used to.

Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was no longer exists. Why?

Human development is based not only on natural biological states, but also on patterns of access to social knowledge. Movement from one social role to another usually involves learning the secrets of the new situation. Children have always been taught adult secrets, but slowly and in stages: traditionally, we tell sixth graders things we keep hidden from fifth graders.

In the last 30 years, however, a secret-revelation(揭示)machine has been installed in 98 percent of American homes. It is called television. Television passes information, and indiscriminately(不加區(qū)分地), to all viewers alike, whether they are children or adults. Unable to resist the temptation, many children turn their attention from printed texts to the less challenging, more vivid moving pictures.

Communication through print, as a matter of fact, allows for a through print, as a matter of fact, allows for a great deal of control over the social information to which children have access. Reading and writing involve a complex code of symbols that must be memorized and practiced. Children must read simple books before they can read complex materials.

to see 30 or 40 patients in a morning,and just have time to say ‘Hello,how do you feel ?…’”

   In Western countries,people are not afraid to admit that they have depression,but most do not tell it to their boss,because they fear that their boss would fire them.
