    【题目】【原创】Humans are well-equipped for life on Earth. But in space, it is different. Low or zero gravity changes how the blood flows and causes motion sickness, muscle loss and tiredness. Weightlessness can also cause bone loss. But scientists are experimenting with little worms to better understand how space travel affects astronauts.

    The millimeter-long worm is called C. elegans. The see-through worm is often used in medical studies because its life is only about two weeks long. Seventy percent of its DNA is the same as human DNA.

    Sabanayagam is a scientist, who built a micro-gravity simulator to test how C. elegans would perform in the actual zero gravity of space.

    Scientists put the worms into the simiulator full of water. After a week they take out the worms. They look for changes in the worms' epigenome,which are chemical markers that tell the DNA in the cells how to perform. The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next.

    "When the worms are in a liquid environment, some epigenomic marks remain even when we take the animal out of the liquid environment and put it back into normal ground conditions. So its offspring keeps this epigenomic memory of the parents' liquid environment or microgravity environment."

    The information the scientists have gathered suggests that the epigenomic marks appear during the early part of a worm’s life.

    Mr. Sabanayagam says he thinks scientists can find genes in the human similar to those in the worms that responded to microgravity and scientists could possibly observe those genes closely when astronauts travel in space.

    Sabanayagam expects C. elegans to visit the International Space Station within two years. He says he hopes information gathered from the worm studies can be used to develop simple, low-cost and quick tests to measure an astronaut's health.

    【1】What does the underlined word” zero gravity” mean?

    A. Seasickness B. Muscle loss

    C. Weightlessness D. Tiredness.

    【2】 From the passage we can know C. elegans _____.

    A. has exactly the same DNA as human

    B. is harmful to human

    C. is often used in agricultural research

    D. has a short life period

    【3】Why do scientists experiment with C. elegans?

    A. Because it has strong life power in water.

    B. Because they want to find how space travel affects astronauts

    C. Because the worm will be taken into space.

    D. Because they want to find what its DNA like.

    【4】What is Sabanayagam’s attitude toward the result of the experiment?

    A. Hopeful and satisfied.

    B. Doubtful and unsure.

    C. Sad and disappointed.

    D. Surprised and unbelievable.

    【5】Which section of a newspaper can you find the passage?

    A. Education. B. Science.

    C. Advertisement. D. Entertainment.

    【题目】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.
