June 26, 2000 — the Human Genome(基因组) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遗传的) map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延长) human life. But those communities and policy makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.
For the last few years, the genetic advances in the developing field of biotechnologyhave provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic codehave opened a world of possibilities for human health, as well as for the popular imagination.
While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.

A.Because the human genome can destroy many illnesses.
B.Because the human genome's completion can help them get rid of many diseases.

He is only 12 years old but Utkarsh Tripathi brings out a handwritten newspaper every week on matters like the environment. He does all this to satisfy his wish to “serve the country”. A Class 8 student of the Brij Bihari Sahai Inter College in Allahabad, Utkarsh has been bringing out the newspaper Jagriti for the last one year. And for the four-page, black-and-white newspaper, Utkarsh not only takes the role of a reporter, editor and publisher, but also gives it free of charge.
Jagriti has about 150 readers belonging to various age groups in Allahabad, some 200 km from the state capital Lucknow. “Children make up major Jagriti readers ... my school friends, my seniors in school, teachers and also my neighbours,” he said.
According to Utkarsh’s father Hari Prasad, who runs a coaching institute, his son has a gift for writing and wants to serve the country in some way.
“More than two years ago, he began to read articles in Hindi Daily. One day he said that he wanted to start serving society from his school life itself. I then suggested why not work like a journalist and make people know their rights,” he added. Utkarsh took the suggestion seriously and came up with Jagriti. “I try to cover social issues about environment, women foeticide and others in the editorial section, and also information about public welfare plans and important government policies for the betterment of the poor or children.” Utkarsh said.
Jagriti also has successful stories of scientists, political leaders and other outstanding people.But how does he get time from his studies to bring out a weekly newspaper? “I believe if anyone is passionate about something, he or she can take out some time to realize his dream.” Utkarsh replied.
Utkarsh’s efforts are much appreciated by people in Allahabad. Nutan Devi, a local journalist, said, “For me it’s real journalism …It has renewed the objective (宗旨) of journalism that seems to have now got lost somewhere.”
According to the text, Utkarsh Tripathi _____.

A.made the first newspaper about two years ago

How much do you hate waiting for another beer in a crowded bar? Josh Goodman invented a pretty obvious solution —self-service beer taps. Goodman, 36, recalled the exact moment in late 2008 when his frustration boiled over. "I was hanging out with my friends at a Baltimore sports bar before an Orioles(金莺队) game," he said. "We just couldn't get another beer served to us quickly."
Even more than annoyed, Goodman was struck by how much money the bar must be losing. Almost immediately, he got to work on a self-service beer concept. Within a few months, Goodman had launched Pour My Beer in Chicago (where he'd relocated to be with his wife).
He invested (投资)$20,000 of his own funds and partnered with a U.S. manufacturer to make beer tables with two to four self-service taps. In February 2009, Goodman landed his first client(客户): A Baltimore tavern. He spent the next two years growing the business and adding more bars and restaurants. In 2011, Pour My Beer introduced self-service "beer walls," which let people pour their own beer from taps on a wall.
Pour My Beer has expanded to over 200 restaurants and bars in 28 states and Canada. The concept will roll out in Chicago's O'Hare International Airport this week and in Italy and Brazil later this year. The tables start at $4,000 and the beer walls cost as much as $16,000. It generated more than $400,000 in sales in 2013 and doubled that in 2014. Goodman expects to take in close to $2 million in revenue this year(2015) —which would make it the company's first profitable(赚钱的)year. "Our business customers tell us that they've cut down on waste and they're selling twice as much beer on average," said Goodman.
The underlined phrase “boiled over” in Paragraph 1 probably means__________.

A.came to an end B.was extremely unbearable
C.threw up D.was too hot

Josh Goodman decided to invent the self-service beer taps when__________.

A.His friends advised him to do so.
B.He realized the loss in waiting for beers.
C.He set up Pour My Beer in Chicago.
D.His company started to make profits.

What can we infer from the passage?

A.Goodman was a businessman before he invented the self-service beer taps.
B.Pour My Beer has expanded to over 200 restaurants in 28 states and Australia.
C.Goodman did his business all by himself at first.
D.Goodman’s company will make more profits in the future.

Which of the following can best describe Josh Goodman?

A.far-sighted B.strong-willed
C.kind-hearted D.bad-tempered

Last week I was riding my special motorbike and then stopped at a convenience store. As I was getting my wheelchair off the back, a man watched me from his car and I noticed a wheelchair in his back seat. We spoke for a moment and I asked him about the wheelchair. He answered that it was for his daughter. “Well, do you think she would like to go for a ride on my motorbike with me?” I asked. He seemed shocked that a total stranger would ask him this. He thought about it for a second and said, “OK, as long as I can follow you.” He introduced me to Amy and he sat her on my back seat. Her father followed me for a few miles and she talked non-stop about what she wanted for Christmas.
As we came back to the convenience store, she said, “This ride is the best Christmas present I could ever receive. I have been in a wheelchair my whole life and didn’t know I could do this.” I told her about some of the other things I do (ski, travel the world by myself, etc.). As her father was taking her off my bike, she turned to him and said, “Oh Daddy, I’m going to be OK. Mr. Bryant does all kinds of things, and I will too.” Her father turned away as a tear of joy rolled down his cheek. He hugged me and said, “I was sitting here praying for a gift for Amy that would encourage her. She often felt that her life was dull compared to other children. God answered my prayer just now. Now I pray that God will bless you for your gift to Amy today.” I believed what he said. Being kind and thoughtful to others, we can be an answer to prayer.

A.He was happy because his daughter could gain excitement.
B.He felt surprised because he didn’t know the author.

Long ago in a small town, there was a place known as the House of 1,000 Mirrors. A small, happy little dog learned of this place and decided to visit it.
When he arrived, he bounced(跳) happily up the stairs to the doorway of the house. He looked through the doorway with his ears lifted high and his tail wagging as fast as it could. To his great surprise, he found himself staring at 1,000 other happy little dogs with their tails wagging just as his. He smiled a great smile, and was answered with 1,000 great smiles just as warm and friendly. As he left the house, he thought to himself, “ This is a wonderful place. I will come back and visit often.”
In this same village, another little dog, who was not quite as happy as the first one, decided to visit the house. He slowly climbed the stairs and hung his head low as he looked into the door. When he saw the 1,000 unfriendly looking dogs staring back at him, he growled at them and was horrified to see 1,000 little dogs growling back at him.
