【題目】 Carol Lee Lindner climbed into the 40-foot boat tied to the Fairmount Boathouse dock, and gave the new members their first lesson in the ancient sport of dragon boating.

The 25 women, aged 29 to 65, watched their coach carefully. All had breast cancer and survived. Their decision to join the Philadelphia Women's Dragon Boat Team was brave and crazy.

Over the months of training, one would be told that cancer had spread to her bones and another would be hospitalized for radiation treatment side effects. But these strong and determined women—each and every one of them—took part in the International Dragon Boat Racing Championship.

In theory, it's a terrible sport for women whose muscles and nerves have been damaged. Doctors generally advised them to avoid hard and repetitive arm exercise. But seven years ago, Canadian Donald Mckenzie, a sports medicine physician, showed dragon boating is good for survivors. “It builds both their physical and mental strength.” Mckenzie said.

Coach Lindner, 60, was inspired by that and included the 25 women in her three-year-old Philadelphia Women's Dragon Boat Team.

The survivors tried hard and did their best. No self-pity.

Renata Whitaker, her hair growing back, began feeling more confident. But she grew tired and easily got out of breath. She had to be in hospital for a week. As she got better she called Lindner, saying she had got well enough to be in the game. Lindner told her if she felt up to it, she would be with the team.

“But you are not going to paddle,” Lindner said, “Remember what I said, “To be strong, fit women for life. I want you by my side for the rest of our lives, not just for one race.”

These women tested their limits. A 500-meter race lasted about three minutes.

As the city darkened in the heat, the team finally paddled toward the Fairmount Boathouse.

Soon, the river was filled with the sounds of painful but happy women singing Merrily We Roll Along.

【1】What do the twenty-five women have in common?

A.They are crazy about dragon boating

B.They are cancer survivors.

C.They were inspired by Donald Mckenzie and have trained together for three years

D.They have broken the record of the International Dragon Boat Racing Championships

【2】Why did Lindner refuse Whitaker's request?

A.Because Whitaker wasn’t really good at paddling.

B.Because Whitaker easily got tired and out of breath.

C.Because Whitaker hadn't recovered completely.

D.Because a new paddler would be in Whitaker's place.

【3】Which of the following will Mckenzie support?

A.Dragon boating will help repair patients' damaged nerves

B.Patients should feel sorry for themselves if they don t take part in dragon boat races

C.Dragon boating will benefit the patients physically and mentally

D.Cancer survivors should avoid hard and repetitive arm exercise

【4】What can we know about Lindner?

A.She enjoys the sport of boat racingB.She is tough with her team members

C.She is also a cancer survivor.D.She is helpful and inspiring.

【題目】 Austin residents and businesses are making efforts to put their leftovers to good use. The city is among a handful of U.S.cities aiming for “zero waste”.

For Austin, there are plenty to go around: it annually wastes more than 190 million pounds of food, worth at least $200 million. Those numbers are big, but they're not out of line with national trends-some 40 percent of food in the nation goes to waste. Put in plain terms, that is enough to fill a 90,000-seat stadium each day.

For many, the answer lies in donation. Austin City Limits, one of the city’s influential festivals, gives all unwanted food to the Central Texas Food Bank. And there are volunteer-driven nonprofits that pick up donated food and deliver it to hungry people.

But the best practice, Austin believes, is to use less, and the city is calling on businesses and households to buy the right amount of food. Full Fridge, a new meal-delivery service, solves this problem. “Full Fridge came about because, basically, we were seeing a lot of people not knowing how to prepare food,” says co-founder Mokshika Sharma. They would buy groceries, but not know what to do with them, and end up throwing away a lot.

Her business hopes to end that problem by offering ready-made meals for only five dollars each. Full Fridge also minimizes waste by stopping sales two days before delivery, so the chef and shopper can plan precisely.

Another satisfactory solution is to compost(將......制成堆肥) it. Austin’s restaurants and grocery stores typically contract with composting companies to deal with much of their food waste, and then sell it as fertilizer. Meanwhile, Compost Pedallers, a company created by Dustin Fedako, is working on bicycle-powered compost collection.

“We play the dot-connecter,” says Fedako, “getting the material from those of us who are making it to the people in the community who use it as a resource to grow more food, and to grow better quality food.”

【1】What do the figures in Paragraph 2 indicate?

A.The urgent need for donated food.B.The rapid growth in food donation.

C.The ambitious goal of “zero waste”.D.The serious problem of food waste.

【2】Paragraph 3 mainly talks about Austin' s efforts to______.

A.feed the hungry.B.make use of leftovers.

C.build more volunteer-driven nonprofits.D.hold festivals to entertain its residents.

【3】Who are Full Fridge's target customers?

A.Those with too little food.B.Those with poor cooking skills.

C.Those with unhealthy eating habits.D.Those with little time to buy groceries.

【4】What does Fedako mean by saying “We play the dot-connecter”?

A.They find it rather easy to collect food waste.

B.They hope people will buy better quality food.

C.They link food waste producers to fertilizer users.

D.They are trying to connect with composting companies.

【題目】 The Great Depression that followed the stock market crash of 1929 saw hundreds of thousands of Americans out of work. In the years of great fear and depression, a lot of American citizens looked desperately to the federal government for assistance. Of all the programs designed by President Roosevelt when he took office in 1932, few were more criticized---or had more lasting impact---than the Work Projects Administration, better known as the WPA.

The intention of the WPA, which functioned from 1935 to 1943, was to design and administer public works projects to help relieve unemployment. The majority of these projects involved historic or artistic attempts. The WPA’s Writers Project, for example, was responsible not only for such practical works as state guidebooks but also for the collection of historically valuable oral histories. Over 2,900 of these records were collected in 24 states. They provide an irreplaceable firsthand account of people’s diets, customs, celebrations, and political and religious beliefs at the time.

The artworks created through the Federal Arts Project are one of the WPA’s most lasting achievements. Out-of-work painters, both famous and unknown, created paintings that beautified schools, libraries, and government buildings, WPA photographers traveled across the country recording the hardships of life on small rural farms. When the United States entered World War Ⅱ in 1941, WPA artists were enlisted to produce posters supporting the war effort. Many WPA artworks, including hundreds of small drawings picturing scenes of everyday life, still exist today.

【1】When did the Work Projects Administration begin to work?

A.In1929.B.In1932.

C.In1935.D.In 1943.

【2】What can be inferred about the WPA?

A.It was made up of several components.

B.It was President Roosevelt’s favorite project.

C.It played an important role during World War Ⅱ.

D.It trained artists before sending them out to work.

【3】How does the author mainly develop this text?

A.By examples.B.By comparison.

C.Through a true story.D.Through a persuasive argument.

【4】What’s the main idea of the text?

A.President Roosevelt designed the WPA.

B.The WPA helped relieve unemployment.

C.WPA artists painted pictures in schools and libraries.

D.The WPA produced many valuable and lasting works.
