Nothing is as precious as one's freedom. Dreams, aspirations and ideals mean nothing if one does not have the freedom to pursue them.

A lot has been done in the name of freedom. A lot has been said and written about freedom. In the past six months, the world witnessed Tunisian uprising, Egyptian revolution and Libyan civil war. Thousands of people fought for freedom; hundreds of people lost their lives (for freedom); people are craving for freedom. But, what exactly is freedom? We are fighting for it, we are ready to die for it, we are craving for it, but, can we really define it?

Albert Camus thinks freedom is a chance to be better. Abraham Lincoln calls it best hope of Earth. Epictetus says it's the right to live as we wish. For Moshe Dayan it's oxygen for soul. According to Urban Dictionary it's everything. And going by Oxford Dictionaries, it's power of self determination attributed to the will.

Everyone has different views about freedom. But somehow I am still not convinced because we can't really be fighting for a chance or hope. And the concept of everything is full of uncertainties. I don't think we are fighting for power of self-determination either. And as for the right to live as we wish, if we have the right to fight, then, how can we be denied the right to live as per our wish?

But the question still remains unanswered, what is freedom?

For me, freedom has a deeper and greater meaning. I think freedom is much more than just a right. It's a responsibility of doing what you think is good, not only for you but even for society. It is a state when one realizes their duties and starts respecting others' freedom.

Freedom is when we realize that we can do absolutely anything except force another person to follow us in our madness or our desire for life. Freedom is when we are no longer slaves to our desires, society, its expectations, luxury or slaves to a life we did not choose.

Freedom is when we have the courage to speak out what we know is true, do what we feel is right, and fight for what we think is unfair. One shouldn't really fight for freedom; rather, they should try to achieve it.

1.How many famous people’s definitions of freedom are mentioned in the passage?

A. 4　　 B. 5　　　 C. 6　　　 D. 7

2.Paragraph 3 mainly tells us that _____________.

A. Everyone longs for freedom

B. Everyone is fighting for freedom

C. People have different views about freedom

D. Famous people have a deeper understanding of freedom

3.Which of the following will the author agree with?

A. Freedom is a chance to live better.

B. Freedom is our best hope in the world.

C. Freedom is the right to live as we wish.

D. Freedom is a responsibility of doing what is good.

4.What is the author’s purpose of writing the passage?

A. To show different views about freedom.

B. To express his understanding of freedom.

C. To encourage us to pursue our dreams and aspirations.

D. To argue against some famous people’s understanding of freedom.

The following is something about extreme sports: Dangerous as they are, extreme sports remain appealing among many Australian young people! Camp extreme sports is the perfect test of your heart.

Kite Surfing

It’s the exciting mixture of kite, board and waves. The idea of using a kite to accelerate speed seems like a new challenge, yet the art of kite flying dates back to the 13th-century Chinese when it was used as a simple means of transport.

Catch a wind and you’re moving — up, down and across the surf. “It’s always exciting. You’d jump 5 feet or 35 feet. You never know if you’re going to go up in the air, and your heart is just going boom, boom, boom.”

Coasteering

It is by far the best activity and the event that everyone is still talking about. This is exploring the coastline without worrying about a coastal path or finding a rocky bay blocking your route. You climb, dive and swim from one place to another. With Coasteering, you don’t have to be able to swim as the wet suit and buoyancy(浮力) aid will keep you floating when you are in the water.

Sky Diving

Traditional parachuting(跳伞) doesn’t sound risky enough. So now sky diving is the name for jumping from a plane and listening to your heart beating heavily as you move fast towards earth before you open your parachute at the last moment.

Mountain Biking

It’s been around so long that bikers are no longer satisfied with just going up and down a mountain. Mountain biking is a sport which consists of riding bicycles off-road, often over rough land, using specially adapted mountain bikes. Mountain bikes share similarities with other bikes, but include features designed to improve strength and performance in rough areas.

Space is a dangerous place, not only because of meteors (流星 ) but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable（可忍受的）. Various kinds of rays come through the air from outer space, but enormous quantities of radiation（辐射） from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

Radiation is the greatest known danger to explorers in space. The unit of radiation is called "rem". Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage - a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will no be discovered until the birth of abnormal children or even grandchildren.

Missions of the Apollo flights have had to cross belts of high amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

1. According to the first paragraph, the atmosphere is essential to man in that ____.

A. it protects him against the harmful rays from space

B. it provides sufficient light for plant growth

C. it supplies the heat necessary for human survival

D. it screens off the falling meteors

2. We know from the passage that ____.

A. exposure to even tiny amounts of radiation is deadly

B. the effect of exposure to radiation is slow in coming

C. radiation is avoidable in space exploration

D. astronauts in spacesuits needn't worry about radiation damage

3. The harm radiation has done to the Apollo crew members ____

A. is significant            B. seems overestimated

C. is enormous             D. remains unknown

4. It can be inferred from the passage that ____.

A. the Apollo mission was very successful

B. protection from space radiation is no easy job

C. astronauts will have deformed children or grandchildren

D. radiation is not a threat to well-protected space explorers

45. The best title for this passage would be ____.

A. The Atmosphere and Our Environment   B. Research on Radiation

C. Effects of Space Radiation             D. Importance of Protection Against Radiation
