Drive through any suburb in the U.S. today,and it's hard to miss the bins that have become companions to America's trash cans.Recycling has become commonplace,as people recognize the need to care for the environment. Yet most people's recycling consciousness extends only as far as paper,bottles,and cans.People seldom find themselves facing the growing problem of e-waste.

E-waste rapidly increases as the techno-fashionable frequently upgrade to the most advanced devices,and the majority of them end up in landfills（垃圾填埋地）.Some people who track such waste say that users throw away nearly 2 million tons of TVs,VCRs,computers,cell phones,and other electronics every year.Unless we can find a safe replacement,this e-waste may get into the ground and poison the water with dangerous toxins（毒素）,such as lead, mercury,and arsenic.Burning the waste also dangerously contaminates the air.

However,e-waste often contains reusable silver.gold.and other electrical materials.Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals,which can destroy ecosystems.

A growing number of states have adopted laws to ban dumping e-waste.Still,less than a quarter of this refuse will reach lawful recycling programs.Some companies advertising safe disposal（处置）in fact merely ship the waste to some developing countries,where it still ends up in landfills.These organizations prevent progress by unsafely disposing of waste in an out-of-sight,out-of-mind location.

However,the small but growing number of cities and corporations that do handle e-waste responsibly represents progress toward making the world a cleaner,better place for us all.

A. Most Americans have realized the dangers of e-waste.

2.What can best replace the underlined word "contaminates" in Paragraph 2?

C. Absorbs. D. Reduces.

3.How does the author feel about burying e-waste m landfills?

C. It's acceptable. D. It's uncommon.

4.What's the author's purpose in writing this text?

Believe it nor not, ancient Chinese people had their own methods of heat preservation in winter.

• “Wen Ding”, ancient rice cooker

The “Wen Ding”, an ancient cooking container, preserved heat by burning fuels like charcoal. The one unearthed in Nanjing in 1989 is thought to be the oldest of its kind discovered in China, dating back to the Stone Age.

• “Ran Lu”, ancient small hot pot

The “Ran Lu” is a small-sized cooking vessel (器皿) made of bronze. A charcoal stove forms the main structure, with a bottom tray to hold charcoal ashes, and a movable cup at the top. Some experts have concluded that the vessel’s structure suggests that these vessels became popular in the Warring States Period (475—221 BC).

• Bronze You, ancient kettle

The Bronze You, one of the most common wine containers during the Shang and Zhou, dynasties, could also be used to warm wine. For example, the Bronze You with beast mask design, unearthed in Jiangxi province, had an opening where charcoals could be placed, allowing people to enjoy a hot drink.

• Bronze Yan, ancient steamer

Although the “Wen Ding” was effective at keeping food warm, ancient Chinese people later found that its burning produced pollution. As a result, the Bronze Van was made with a two-tier (双层的) structure and used to steam rice and other grains. After the Eastern Han Dynasty (AD 25-AD 220), further improvements to the Bronze Yan led to the modern day steamer.

1.When did the “Ran Lu” begin to gain popularity?

A. In the Zhou Dynasty B. In the Warring States Period.

C. In the Eastern Han Dynasty. D. In the Stone Age.

2.One of the main functions of the Bronze You was to .

A. place hot charcoals B. pour hot water

C. keep wine warm D. hold charcoal ashes

3.One advantage the Bronze Yan had over the “Wen Ding” was that .

A. it was useful B. it was convenient

C. it was environment-friendly D. it was warm

4.According to the passage, which of the following may have the longest history?

A. The "Wen Ding”. B. The “Ran Lu”.

C. The Bronze You. D. The Bronze Yan.

My mom was one-eyed. I hated her... She was such an embarrassment. She ran a small shop at a flea market to sell anything for the money we needed.

I remember it was field day, and my mom came. I was so embarrassed. I threw her a hateful look and ran out. The next day at school..., “Your mom only has one eye?!” and they teased me.

I wished my mom would disappear from this world, so I said to her, “Why don’t you have the other eye?! You’re only going to make me a laughing stock. Why don’t you just die?” She didn’t respond. I guess I felt a little bad, but meanwhile, it felt good to think I said what I’d wanted to say.

That night, I woke up, and went to the kitchen to get water. My mom was crying quietly. I looked at her, and turned away. Because of what I had said to her earlier, there was something hurting in my heart. Even so, I hated my mother who was crying from her one eye. So I told myself I would grow up and become successful, because I hated my one-eyed mom and our poverty.

Then I left her and got accepted in the Seoul University. Then, I got married. I bought a house then had kids. Now I’m living happily as a successful man. I like it here because it’s a place that doesn’t remind me of my mom.

This happiness was getting bigger when someone unexpected came to see me. It was my mom... Still with her one eye. My little girl ran away, scared of her eye.

I screamed at her, “How dare you come to my house and scare my daughter! Get out of here now!!” And to this, my mother quietly answered, “Sorry. I may have gotten the wrong address.” and she disappeared. Thank goodness. She doesn’t recognize me. I was relieved. I told myself I wasn’t going to think about this for the rest of my life.

One day, a letter regarding a school reunion came to me. I lied to my wife saying I was going on a business trip. After the reunion, I went down to what I used to call a house. I found my mother fallen on the ground. She had a piece of paper in her hand. It was to me.

My son, I was glad when I heard you were coming for the reunion. But I decided not to go to the school. For you... sorry I only have one eye. When you were little, you lost your eye. As a mother, I couldn’t stand watching you grow up with only one eye, so I gave you mine. I was so proud of my son seeing a whole new world for me with that eye. I was never upset at you for anything you did. You mean the world to me.

My world fell apart. I hated the person who only lived for me. I didn’t know of any way that will make up for my worst deeds.

A. He felt guilty of what he had said to her.

B. He felt good to speak out all he’d wanted to say.

Elizabeth Blackwell was the first woman doctor in the United States. Her success opened the way for other women who wanted to do more than nursing. She was born in England in 1821 and her family moved to America when she was eleven years old.

The Blackwell girls received the same education as their brothers. This was most unusual in those days. Their father died young and they had very little money to live on. Elizabeth and her sisters taught at school. Then a woman dying of cancer urged Elizabeth to study medicine, saying that a woman doctor would have saved her from her worst sufferings. Nearly everyone said a girl should not go to medical school, but she managed to enter Geneva College in New York State. She graduated in 1849 at the head of her class and received the first medical degree ever given to a woman.

Next, Dr. Blackwell went to Paris. Her only chance of training was in a hospital where women came to have their babies. Four months later, while she was working in the French hospital, her left eye became dangerously infected (感染). She lost the eye. She was very disappointed. But she was soon back at work again, this time in London, England. There she met many famous scientists.

In 1859, Elizabeth Blackwell was officially recognized as a doctor in Great Britain — the first woman to be honored. She was the inspiration of Elizabeth Garrett, who began the women’s medical movement in England. Florence Nightingale, founder of the practice of nursing by women, was another of her friends.

Dr. Blackwell died in 1910 at the age of 89.

C. get practical experience D. earn money for their education

2.What made Elizabeth decide to study medicine?

A. The education she received. B. The death of her father.

a. Elizabeth Blackwell lost one eye.

b. Elizabeth Blackwell received a doctor’s degree.

c. Elizabeth Blackwell entered Geneva College.

d. Elizabeth Blackwell was recognized as a doctor.

e. Elizabeth Blackwell went to work in London.

A. cabed B. cbaed

C. acbed D. bcade

4.What can we infer from the last two paragraphs?
