Owning a Pet Is Good for Your Health

Pets in America are incredibly well loved: according to a 2015 Harris poll, 95% of owners think of their animal as a member of the family. About half buy     1     birthday presents. And it’s a two-way street. People who have pets tend to have lower blood pressure, heart rate and heart-disease risk than those who don’t. Those health benefits may come from the extra exercise that playing and walking     2     (require), and the stress relief of having a steady best friend on hand.

Scientists are now digging up evidence     3     animals can also help improve mental health, even for people with challenging disorders. Small     4     the studies are, the benefits are impressive enough that clinical settings are opening their doors to animal assisted interventions — pet therapy, in other words — used alongside conventional medicine. “    5     (think) of an animal in a hospital used to be one of the great no-no’s,” says Alan Beck, director of the Center for the Human-Animal Bond at Purdue University, citing the fear of causing infection. “Now, I don’t know of any major children’s hospital     6     at least some kind of animal program.”

The rise of animal therapy     7     (back) by increasingly serious science showing that social support — a proven antidote to anxiety and loneliness — can come on four legs, not just two. Animals of many types can help calm stress, fear and anxiety in young children, the elderly and everyone in between.

More research is needed     8     scientists know exactly why it works and how much animal interaction is needed for the best results. But     9     (publish) studies show that paws have a place in medicine and in mental well-being. “The data is strong,” Beck says. “If you look at     10     animals do for people and how we interact with them, it’s not surprising at all.”

Giant panda Ya Ya returned home to Beijing Zoo early on Monday after spending 20 years in the United States.

In 2003, Ya Ya and male giant panda Le Le, traveled to Memphis Zoo in the US state of Tennesse    1    part of a China-US giant panda protection and research program. In 2006, Ya Ya began to shed her fur, a condition that    2    (worse)in 2014. Experts at Memphis Zoo and in China tried various treatments, but were    3    (able)to solve the problem. Then Memphis Zoo announced that it would return the pandas. However, in February, Le Le passed away due to heart disease. On April 8, the zoo hosted a farewell party for Ya Ya, with hundreds of people    4    (attend)the event.

On April 27,giant panda Ya Ya arrived in Shanghai and was then quarantined（检疫） for a month    5    delivered to Beijing. During the quarantine period,    6    (experience) keepers and veterinarians provided round-the-clock care for Ya Ya due to her old age and changed living environment.

Forests give us shade, quiet and one of the harder challenges in the fight against climate change. Even as we humans count on forests to soak up a good share of the carbon dioxide we produce, we    1     (threaten) their ability to do so. The climate change we are hastening could one day leave us with forests that emit more carbon than    2    absorb.

Thankfully, there is a way out of this trap—but it involves striking a subtle balance. Helping forests flourish as valuable “carbon sinks” long into the future    3       require reducing their capacity to absorb carbon now. California is leading the way, as it does on so many climate efforts, in figuring out the details.

The state's proposed Forest Carbon Plan aims to double efforts    4    (thin) out young trees and clear brush in parts of the forest. This temporarily lowers carbon-carrying capacity. But the remaining trees draw a greater share of the available moisture, so they grow and thrive,     5    (restore) the forest's capacity to pull carbon from the air. Healthy trees are also better able to fend off (抵挡) insects. The landscape is considered less easily burnable. Even in the event of a fire, fewer trees    6     (consume).

The need    7    such planning is increasingly urgent. Already, since 20l0, drought and insects have killed over 100 million trees in California, most of them in 2016 alone，and wildfires have burned hundreds of thousands of acres.

California plans to treat 35,000 acres of forest a year by 2020, and 60,000 by 2030—financed from the proceeds of the state's emissions-permit auctions. That's only    8     small share of the total acreage that could benefit, about half a million acres in all, so it will be vital to prioritize areas at greatest risk of fire or drought.

State governments are well accustomed to managing forests,     9     traditionally they've focused on wildlife, watersheds and opportunities for recreation. Only recently have they come to see the vital part forests will have to play in storing carbon. Califomia's plan,     10     is expected to be finalized by the governor next year, should serve as a model.

In my entire life, I have never witnessed an environmental disaster like the     1     (disappear) South Aral Sea in Central Asia. As I drove on the deserted road, away from the town of Moynaq and toward the sea, I felt a deep and     2     (continue) sadness. This area was once home     3     a large and busy fishing community. Over the past 40 years, however, it     4     (become) a ghostly desert. There was no greenery anywhere. The only things I could see on the horizon were the old     5     (abandon) ships sitting on the dry sea floor. I stared at the rusted and rundown structures for what felt like hours. I do not know how long they had been there, but     6     sight of them filled me with sorrow. How could a place that once thrived (繁荣) on fishing and other     7     (activity) become so dry? My guide told me that I would have to walk dozens of kilometers on the cracked soil to     8     (eventual) see the blue water that used to flow to     9     I was standing. I breathed deeply and tasted the salty remains of the ocean. The environmental disaster of the South Aral Sea will stay with     10     (I) forever.
