When she was studying to become a scientist, Megan Strauss rode in a small airplane to study giraffes. While a pilot flew over the Serengeti in Tanzania, Africa, the researchers looked down carefully and counted giraffes.
"I am always amazed how easily we can spot warthogs and other small animals, yet we sometimes have trouble seeing giraffes. Giraffes are slender in shape, and they may not throw a good shadow, " says Dr. Strauss, who has since become a wildlife scientist.
The Serengeti is about the size of Vermont, a state in the northeastern US, so the scientists could not study the entire area. Instead, they surveyed three areas where giraffes were studied in the 1970s. As they expected, they saw far fewer of these animals.
To find out if lions had been killing more giraffes in recent years, the team looked at the survival of young giraffes. Lions kill more young giraffes than adults, but the team found no decrease in young giraffes' survival after they are born, compared with the 1970s.
The team then looked at whether too many giraffes were being killed by parasites(寄生虫).The researchers counted parasite eggs in giraffe droppings, and they found too few to harm the giraffe population.
They looked into whether poachers (盗猎者)were killing too many giraffes. Two of the areas they studied are where giraffe meat is sometimes sold in local markets. Poachers catch more adult males than other giraffes. Researchers spotted too few males compared with females in those two areas, a sign of poaching.
When the food supply is short, the environment supports fewer giraffes and the females have fewer young giraffes. A lot of new trees have grown in the Serengeti, but many are a type that giraffes do not like to eat. The researchers found fewer young giraffes today than in the 1970s compared with the number of adult females, a sign that food was in short supply.
Dr. Strauss is working on an environmental education program for Tanzania including books for students. These materials will educate Tanzanians and help them to help giraffes. As knowledge grows and changes are made, they hope the giraffe population will increase.
1.What did Dr. Strauss find while studying giraffes in the Serengeti?
A.It was too costly to study giraffes.
B.It was hard to spot giraffes from the air.
C.The number of giraffes had increased slowly.
D.Giraffes lived in smaller areas than in the 1970s.
2.How did the team study the lion-giraffe relationship?
A.By analyzing giraffe droppings.
B.By comparing young giraffes with adults.
C.By comparing male giraffes and females.
D.By surveying the survival of young giraffes.
3.What is Dr. Strauss doing to help giraffes?
A.She is founding a national park in Tanzania.
B.She is counting giraffes in the entire Serengeti.
C.She is educating students to write about giraffes.
D.She is raising environmental awareness in local people.

When Veronika Scott was a student at the College for Creative Studies in Detroit, Michigan, she received a task to “design to fill a need.” She dreamed up an idea for overcoats that would double as sleeping bags, made 25 of them, and handed them out to people living in shelters on an abandoned city playground. While her efforts were greeted mostly with enthusiasm from those braving Detroit’s cold winters, one woman voiced dissatisfaction. “We don’t need coats; we need jobs,” she told Veronika. Then she had her second inspiration.
After graduating from college in 2012, Veronika founded the Empowerment Plan, a nonprofit organization. She hired two homeless women to sew the coats and paid them with donations she received through her blog. Now, the Empowerment Plan employs about 20 people and has produced more than 10,000 coats and distributed them in 30 states, Canada, and elsewhere abroad.
“We don’t require previous employment,” Veronika says. “We’re looking for people who are motivated.” The Empowerment Plan provides free classes and lends money to those who qualify. Nearly all the employees eventually move into permanent housing, and some go on to jobs in the auto industry and construction.
Veronika has bettered the coat’s design by making its outer layer of a lightweight material that resists air, wind, and water and its inner layer of a material that stores body heat. Still, Veronika is less focused on the coats than on the workers who make them. “At the end of the day,” she says, “the coat is a vehicle for us to employ people.”
1.What was Veronika’s second inspiration?
A. Improving her coat’s design.
B. Founding a nonprofit organization.
C. Profiting from the work of those low-paid people.
D. Producing more coats and distributing them abroad.
2.What is the purpose of the Empowerment Plan?
A. To raise more donations.
B. To design better clothes.
C. To provide help for the homeless.
D. To offer free classes to the motivated.
3.Which of the following best describes Veronika?
A. Traditional but helpful B. Greedy and unsatisfied.
C. Generous but childish. D. Creative and caring.
4.Which is the best title of the passage?
A. Design to Fill a Need. B. The Empowerment Plan.
C. Look for Motivated People. D. How to design a coat.

At the age of 16, Clara Barton was advised to become a teacher, since she was quite shy. She taught in Massachusetts for ten years, and was invited to Bordentown, New Jersey, to teach in a private school. She saw personally that these communities needed free education for their citizens, and she responded by creating a free school, one of the first in her state. Later, officials ignored her and appointed a male as principal instead. She resigned and moved to Washington DC, becoming the first woman employed by the U. S. Patent Office.
Clara Barton was forever changed by her experience with the troops in the Civil War. She saw surgeons dressing wounds with cornhusks（玉米叶）, since they had nothing else. The medical supplies for the Army were well behind the troops, who were moving faster than their medical supply lines. She brought in a wagon of bandages and medical supplies that she had collected personally beforehand. Barton continued to work on the battlefields throughout the war.
She helped in the identification process of 13,000 dead Union soldiers. Afterward, she was an important figure in a campaign to identify missing soldiers from the Civil War. This non-stop work debilitated her, and upon recommendation by her physicians, she traveled to Europe to recover herself.
While in Europe, and still in poor health Miss Barton was moved by the hardship on civilians brought about by the France-Prussia war. She helped in their relief effort, and in that work she was inspired to create the Red Cross, which served all troops and civilians.
Clara Barton returned to America and then began the establishment of the American Red Cross. The US government did not think there would ever be another war, after the horror of the Civil War. But she convinced them that the Red Cross would be valuable to serve in times of natural disasters, as well. This was her lasting legacy（遗产）, an agency that still provides aid to victims today.
1.What does this text mainly tell us about?
A. The establishment of the American Red Cross.
B. A general introduction of Clara Barton’s life.
C. Clara Barton’s contribution to the Red Cross.
D. Clara Barton’s service in the army.
2.Why did Clara give up her job in the free school?
A. Because officials didn’t make her principal.
B. Because she wanted to work in a Patent Office.
C. Because she wanted to serve in the army.
D. Because she was not satisfied with the pay.
3.The underlined word “debilitated” in the third paragraph means .
