In every photo from our family vacation to Washington, D.C., I was showing off the souvenir I picked out at the Smithsonian’s National Zoo — a white, oversize, cotton sweatshirt with pandas     1     (dance) on the front.

Nearly 30 years later I found myself among     2     pool of photojournalists and video crews packed into the panda enclosure(围场), covering a small cub(幼兽) named Bei Bei for National Geographic.

After the photographs of Bei Bei     3     (publish), my editor suggested I ask zoo administrators if I could return periodically     4     (document) the first year of the cub’s life. They said yes.

On that first day with Bei Bei, I felt a little thrill as a zoo staffer took me down a quiet path to the back of the panda enclosure     5     the panda’s keepers were waiting. They introduced     6     (they), handed me shoe coverings and a mask, and led me through a series of gates and     7     (eventual) to Bei Bei.

Soon I was making regular     8     (stop) at the zoo to record the baby panda’s transformation. My kids had never been     9     (interested) in my job than when I was on the Bei Bei beat. When I mentioned the project     10     friends and neighbors, they would light up in ways I’d never seen. It turned out that everyone loved pandas.

According to the Food and Agriculture Organization of the United Nations, one third of the world’s fisheries are being pushed beyond     1     (they) natural limits. Overfishing goes hand in hand with bycatch (副渔获物). Bycatch is that unwanted sea life     2    (catch) along with the desired catch and then thrown away. As    3    result, billions of fish along with seabirds, sea turtles and millions of sharks are lost. Bycatch is     4    (probable) the most important threat to sea turtles now.

The Marine Stewardship Council (MSC) (海洋管理委员会) has been working with scientists, fisheries and seafood    5    (producer) for more than 20 years. They     6    (develop) standards for sustainable fishing 20 years ago. Around 15 percent of wild-capture fisheries are now MSC certified. And Fishery Improvement Projects (FIPS) in many countries are working     7    ( increase) that percentage.

What can you do? Look for MSC's bluefish label,     8    appears on over 30, 000 products and menus in almost 100 countries. Buying a product with this label means you’re supporting a fishery that is contributing to a     9    (healthy) ocean than before. And that will help protect both the ocean    10    the fish for years to come.
