【题目】The Swiss army knife is a popular device that is recognized all over the world. In Switzerland, there is a saying that every good Swiss citizen has one in his or her pocket. But the knife had poor beginnings.

In the late nineteenth century, the Swiss army issued (发给) its soldiers a gun that required a special screwdriver (螺丝刀) to take it apart and clean it. At the same time, canned food was becoming common in the army. Swiss generals decided to issue each soldier a standard knife to serve both as a screwdriver and a can opener.

It was a lifesaver for Swiss knife makers, who were struggling to ask for cheaper German imports. In 1884, Carl Elsener, head of the Swiss knife manufacturer (maker) Victorinox, seized that opportunity with both hands, and designed a soldier’s knife that the army loved .It was a simple knife with one big blade (刀片), a can opener, and a screwdriver.

A few years after the soldier’s knife was issued, the “Schweizer Offizer Messer,” or Swiss Officer’s Knife, came on the market, Interestingly, the Officer’s Knife was never given to those serving in the army. The Swiss army purchasers considered the new model with a corkscrew (瓶塞钻) for opening wine not “essential for survival,” so officers had to buy this new model by themselves. But its special multi-functional design later launched(发行)the knife as a global brand. After the Second World War, a great number of American soldiers were stationed in Europe. And as they could buy the Swiss army knife at shops on army bases, they bought huge quantities of them. However, it seems that “Schweizer Offizer Messer” was too difficult for them to say, so they just called it the Swiss army knife, and that is the name it is now known by all over the world.

【1】What is the main purpose of the passage?

A. To emphasize the importance of the Swiss army knife.

B. To introduce the functions of the Swiss army knife.

C. To explain the origin of Swiss army knife.

D. To tell a story about the designer of the Swiss army knife.

【2】What does “It” in the third paragraph refer to?

A. Canned food was becoming popular in Swiss army.

B. Every good Swiss citizen had a knife in his pocket.

C. The Swiss army needed a knife for every soldier.

D. Swiss knives were competing with imported knives.

【3】Why didn’t the Swiss army purchase the Swiss Officer’s Knife?

A. The new design was not considered necessary for officers to own.

B. The army had no budge to the purchase.

C. The knife was sold out to American soldiers.

D. The design of the knife was too simple.

【题目】Utopia is a perfect place. It is a place without war, hunger, poverty, or crime. It is a place where the people work together and share. There is no money in Utopia because the people do not need money. They do not have personal possessions because everything belongs to everyone. All of the people are equal in Utopia, and the laws are all fair.

Utopia is not a new place. Plato, the ancient Greek philosopher, described a perfect society in his famous dialogue The Republic. In Plato’s Republic, philosophers were the kings, and every person had a place in the society. In 1516, Sir Thomas More wrote about an island in the Pacific Ocean where everything was perfect. He named the island

“ Utopia”. In 1602, Tommaso Campanella wrote The City in the Sun about a perfect community on the island of Ceylon ( now Sri Lanka ) ; and in 1872, Samuel Butler wrote a novel about a perfect country which he named “ Erewhon”. “ Utopia” is a Greek word that means “ not a place”, and “Erewhon” is the English word “ nowhere” spelled backwards.

Utopia is a perfect place, but it is not a real place. Most ‘real’ Utopias last only a short time. This is because everyone wants to live in it, but no one knows how to make it work. As a result, when we say something is ‘ Utopia’ today, we mean that it is a good idea, but it is not realistic.

【1】Which of the following would be the best title for this passage?

A. A place without war B. A Good Idea

C. A Perfect Place D. The Utopian Community

C. Samuel Butler and D. Sir Thomas More

【4】“Utopia”is a word which came from _________

A. English B. Greek C. French D. Chinese

【5】According to the passage, most ‘real’ Utopias last only a short time because _______.

A. no one wants to be a leader

B. no one knows how to make a perfect society

C. it is difficult to collect money

D. everyone wants to live in Utopia

【题目】In my dual（双重的） profession as an educator and health care provider, I have worked with numerous children infected with the virus that causes AIDS. The relationships that I have had with these special kids have been gifts in my life．They have taught me so many things，but I have especially learned that great courage can be found in the smallest of packages．Let me tell you about Tyler．

Tyler was born infected with HIV；his mother was also infected. From the very beginning of his life, he was dependent on medications（药物） to enable him to survive. When he was five, he had a tube surgically inserted in a vein in his chest. This tube was connected to a pump, which he carried in a small backpack on his back．Medications were hooked up to this pump and were continuously supplied through this tube to his bloodstream. At times, he also needed supplemented oxygen to support his breathing．

Tyler wasn't willing to give up one single moment of his childhood to this deadly disease. It was not unusual to find him playing and racing around his backyard，wearing his medicine－laden backpack and dragging his tank of oxygen behind him in his little wagon. All of us who knew Tyler marveled at his pure joy in being alive and the energy it gave him. Tyler's mom often teased him by telling him that he moved so fast she needed to dress him in red. That way, when she peered through the window to check on him playing in the yard，she could quickly spot him．

This dreaded disease eventually wore down even the likes of a little dynamo like Tyler．He grew quite ill and，unfortunately，so did his HIV－infected mother．When it became apparent that he wasn't going to survive，Tyler's mom talked to him about death．She comforted him by telling Tyler that she was dying too，and that s he would be with him soon in heaven．

A few days before his death，Tyler beckoned10) me over to his hospital bed and whispered，“I might die soon．I'm not scared．When I die，please dress me in red．Mom promised she's coming to heaven，too．I'll be playing when she gets there，and I want to make sure she can find me．”

【1】What’s the profession of the writer? (no more than 8 words.)

【2】Why did Tyler carry a small backpack on his back? (no more than 13 words)

【3】Why did Tyler’s mother want to dress Tyler in red? (no more than 14 words)

【4】Try to use at least three words to describe Tyler’s personality. (no more than 4 words)

【题目】The US will seek to expand its own oil production in an attempt to reduce dependence on imported oil and bring down fuel prices, President Obama says. New contracts for exploration will be signed in non-protected areas of Alaska and in the Gulf of Mexico.

In his weekly speech, the President insisted the US could reduce its need for imported oil and improve safety. Using his speech to tell Americans that he understood their concerns about rising prices, President Obama focused particularly on the price of fuel, which has risen in recent months.

US consumers have historically enjoyed cheap fuel, but have seen prices rise in recent months even though US oil production in 2010 reached its highest level for seven years.

Although the oil spill in the Gulf of Mexico in 2010 was serious, Mr. Obama said the Gulf remained a key part of the country’s future energy supply.

The President’s proposals (议案) come after Republicans (共和党人) introduced a series of proposals that would expand and speed up oil and gas production.

The White House has criticized the Republican proposals for safety reasons, but Mr. Obama was clear in his speech that he felt safety and environmental standards could be maintained even though production might rise.

“I believe that we should continue to expand oil production in America — even as we increase safety and environmental standards,” he said.

“As a nation, we should be investing in the clean, renewable sources of energy that are the solution to high gas prices.”

Mr. Obama has previously called for a step-change in energy policy, saying the US must move towards getting 80% of its electricity from clean energy sources by 2035.

【1】Which of the following is NOT included in Mr. Obama’s speech?

A. The dependence on imported oil.

B. Improving safety standards.

C. The reason for the rising oil prices.

D. Expanding oil production.

【2】Mr. Obama thinks the Republican proposals are ______.

A. not safe enough

B. not environmentally friendly

C. practical

D. clear

【3】What can we learn from the text?

A. The US has got most of its electricity from clean energy.

B. US oil production is too small to keep the present low fuel prices.

C. The US produced the most oil in 2010 in its history.

D. The Gulf is still important in energy supply in spite of the oil spill in 2010.

【4】Which of the following can serve as the title?

A. Obama: US will seek oil in Alaska and Gulf of Mexico

B. Obama: US will import less oil to improve safety and environmental standards

C. Obama: the time of high fuel prices will be gone

D. Obama: clean, renewable sources of energy are the solution to high gas price.
