一 Although  I live         , I don't feel          .

    My guide dog, Amelia, has been with me for more than three years. She has given me courage to enjoy life.

    My most difficult time was when I knew" I got cancer(癌症). Amelia was there for me all the way. She helped me beat(打败) the illness. For seven weeks, I had to have radiation therapy（放射） five days a week. Each time we arrived in front of the hospital, Amelia knew where we were. All I had to say was: Amelia, take Mommy to the room. After a few trips, honestly, I even didn't need to tell her which room we had to get into. She knew the way. Without Amelia's help, I would not have the courage to go through the hardest time.

    Today our journey still goes on with fun and happiness. In the past few years, we have visited many places and have met many wonderful people. To me, Amelia is not only a dog but a family member. She always brings me happiness and I love her so much.

    To save time, many Americans buy foods which can be （quick）made ready for the table. On holidays, families enjoy （have）delicious meals. For example. On Thanksgiving Day, the （four）Thursday in November, family members get together for a turkey dinner with pumpkin pie.

    The United States is known the world for （it）fast food, such as （hamburger）, sandwiches, pizzas, salad bars, many kinds of ice-cream. People can easily （find）fast food chains（连锁店）, such as McDonalds' and KFC, in most of the big cities in the world. However, many people think that fast food isn't （health）for us although it can help people save （many）time.

In the 1700s, many people believed that space was supernatural. They thought events in the sky happened when gods were unhappy. Some of these events were eclipses (日食). Eclipses result from objects moving in space. These objects may be planets or moons. During an eclipse, one object passes through the shadow of another.

But Wang Zhenyi thought differently. She was a scientist in China. Wang believed in facts and observation (观测). She used experiments to understand difficult ideas. This included eclipses.

Throughout her life, Wang wrote many articles about her research. She shared her findings with scientists and the public. She wanted everyone to understand her work. She thought science should be available to all.

Wang Zhenyi was born in what is now Nanjing, China. She grew up in the late 1700s. Back then, girls were not able to get a formal education. But her father and grandfather were scholars (学者). They pushed her to read and educate herself.

She read about math. She also read about astronomy. That is the scientific study of stars, planets and space. She read medicine books and poetry.

Later, Wang met other female scholars. She decided to focus on studying astronomy and math. She also started writing poetry.

Wang couldn't go into a lab. So she did experiments (实验) at home. In one, she used a round table, a lamp and a mirror. The table was Earth. The lamp was the sun. The mirror was the moon. She moved them around to understand their movements. By doing so, she showed what truly happened during eclipses.

Wang showed that the moon can block our view of the sun. This demonstrated (演示) a solar eclipse. It happens when the moon moves between the sun and Earth. It lasts for a short time. Wang also showed that the Earth can block sunlight from reaching the moon. This demonstrated a lunar eclipse. It happens when Earth gets in the way of the sun. Its light cannot hit the moon. During a lunar eclipse a full moon disappears. The shadow of Earth covers it up.

Wang felt it was not fair that girls could not get an education. It hurt science. Her poems often addressed these inequalities.

In one poem, she wrote, "It's made to believe, Women are the same as Men; Are you not convinced, Daughters can also be heroic?"
