A new study found that    1    (own) a pet— particularly a dog—is good for the owner’s heart health.

The study looked at 1,768 people from Czech Republic and assessed (评估) them on seven kinds of health    2     (behave). Researchers then    3     (compare) the heart health scores of pet owners with those who didn’t own pets.

“In general, people       4     owned any pet were more likely to do more physical activities, better diet and blood sugar at an ideal (理想的) level,” researcher Andrea Maugeri said.“People who owned a dog can get the greatest     5     (beneficial) from having a pet.”

“Keeping a pet could be a    6     (hope) way of improving heart health,” Maugeri added, “because it would make you have a more    7     (physical) active lifestyle.”

In fact, the study is not the first to suggest that dogs can do good    8     our hearts. In 2013, the AHA said that dog owners have a    9     (low) risk of heart disease than people who don’t keep dogs because people with dogs    10     (be) more physically active.

2 . The study ended in 2003, but they were unwilling to return home.     1     So they founded Equus Silvanin, a self-sustaining farm. Here they brought up two daughters while tending to 35 horses. They also kept pigs, chicken, geese and ducks, and grew a large variety of fruits and vegetables.

    2     “Most of the local owners had little economic mind for the land and preferred to sell it, or its resources, to businessmen to make profits,” says Christoph. For the forests, and the animals living in them, the change was catastrophic. Vast areas of woodland, unchanged for thousands of years, were vanishing, eaten up by the biting teeth of power saws as illegal logging swept through the forest.     3     There were no animals because the undergrowth protecting them had been torn away, leaving a scarred, broken landscape.

“It broke my heart to see that someone could do this to such a beautiful place,” says Christoph. “If you care for nature and for the conservation of our environment, you cannot tolerate such scenes.”     4     Thus before Christmas 2009, Foundation Conservation Carpathia was born.

Barbara and Christoph networked tirelessly, tapping into all of their conservation friends and contacts. “We found that more and more people were becoming committed to the idea of forest conservation, says Christoph. It's a struggle to change the perceptions of people to their environment. They have had car tyres slashed, and once had their lives threatened by a man who illegally grazed his cattle on land that was off limits.     5

3 . Migratory birds face numerous threats throughout their annual cycles from both natural and human-caused sources. The U. S Fish& Wildlife Service is working with governments, conservation organizations, industry and the public to reduce threats across the North American landscape to preserve our birds for future generations. There are also many easy ways anyone in the general public can help protect birds around your communities.

Many of the 1,027 species of birds protected under the Migratory Bird Treaty Act are experiencing population declines due to increased threats from both natural and human-caused sources. Millions of acres of bird habitats are lost or degraded every year due to development, agriculture, and forestry practices. These rapidly accelerating impacts can be mitigated only through habitat restoration and protection. In addition, millions of birds are directly killed by human caused sources such as collisions with man-made structures. Death from natural causes is also common sources of mortality(死亡率).

The mission of the Fish& Wildlife Service includes working with others to conserve natural resources. In addition, it provides information and assistance to industry and the public seeking to develop projects in a manner that reduces impacts on birds and their habitats. Some of the resources, the Service provides and is constantly improving upon, are voluntary guidelines, best practice recommendations and information for developers to conduct environmental reviews striving for bird-friendly projects. This information empowers the public to understand potential impacts from various activities and provides recommendations on how to avoid or minimize those impacts.

Migratory birds' conservation is a critical and challenging task for the Fish& Wildlife Service and all who value nature. Everyone can help protect migratory birds. Whether it is taking actions around your home or workplace, designing bird-friendly projects, or just taking actions that reduce resource consumption, every action is one step towards protecting migratory birds for future generations.

Yuan Longping, Father of Hybrid Rice,     1     passed away on Saturday at 91, will be long remembered as one of the most honorable leaders, the World Food Prize Foundation said.

Yuan was a co-winner of the 2004 World Food Prize, the top international honor recognizing the deeds of     2     (individual) who have advanced human development by     3     (improve) the quality, quantity and availability of food in the world. Yuan shared it with Monty Jones, an African rice breeder.

Yuan’s pioneering research has     4     (complete) helped transform China from food shortage to food security within three decades, according to an earlier statement     5    (release) by the WFP.

Barbara Stinson, president of the WFP Foundation, said Yuan was credited not only for hybrid rice, but also for the ability     6    (change) land out of rice production and into other kinds of food production, including fish ponds, other fruits and vegetables, increasing the nutritional content of food in China, and contributing     7     the reduction of hunger and poverty as well.

Yuan started hybrid rice research in 1964 and     8    (succeed) in developing the world’s first high-yield hybrid rice strain in 1973. So far, its annual growth area     9    (reach) 8 million hectares (公顷)in countries including India, Bangladesh, Vietnam) Brazil and the US.

5 . For 30 years, Alaska's northern fur seal population has not increased. But the ocean mammals are appearing in growing numbers in one unlikely place-a small island that forms the tip of an active undersea volcano. Bogoslof Island is distant and unpopulated. It sits in the eastern Bering Sea. Openings on the ground there release mud, steam and sulfurous gases, but northern fur seals find the island to be a good place for giving birth and raising their young.

It is unclear why the seals have chosen to live on an active volcanic island instead of other unpopulated islands in the area. "The surface is covered with these big blocks, some as big as 10 meters in length, which were exploded out of the vent,” said Chris Waythomas, a U.S. Geological Survey research scientist.

Northern fur seals get their name from their extremely thick fur; they have about 60,000 hairs per square centimeter. When Russian Emperor Alexander II needed money and decided to sell Alaska to the United States in 1867, fur was one of the future state's known valuables.

Most of the world's northern fur seals live in the eastern Bering Sea area. They live in the ocean from November to June and return to land in summer, when they breed and nurse pups. Between 1950 and 1988, the northern fur seal population dropped from 2.1 million to 1.1 million. Scientists do not know why they have not made a comeback. Northern fur seals were first seen on Bogoslof in 1980. NOAA researchers have since carried out periodic studies of the population.

Volcanic activity on Bogoslof has remained mostly stable. But Gelatt's crew chose not to camp there during their week-long visit in August. They feared an explosion could shoot up huge rocks. Instead, they made day trips from a secured boat. The crew counted the number of seals and examined whether images taken from above by an unpiloted aircraft could be used in future counts.

1. What's the text mainly about?

A．The scientists are worried about the extinction of seals.

B．The environment protection is crucial to wild animals.

C．The northern fur seals are on the rise on Bogoslof Island.

D．The northern fur seals like distant and unpopulated places.

2. What do Chris Waythomas^’ words mean?

A．The conditions on Bogoslof Island are tough and terrible.

B．An active undersea volcano makes Bogoslof Island livable.

C．Bogoslof Island is suitable for the northern fur seals to live on

D．It's reasonable for the northern fur seals to live on a small island.

3. What can be learned from the paragraph 3 & 4?

A．The northern fur seals breed and nurse pups in winter.

B．The northern fur seals' thick fur is of no value nowadays.

C．There were about 1.1 million northern fur seals on the island.

D．It's not clear why northern fur seal population has not increased.

4. How did researchers guarantee their safety during the study?

A．By observing in the distance.

B．By doing the research inside an aircraft.

C．By taking a boat with protective equipment every day.

D．By using photos shot by an unmanned vehicle to count seals.
