Feeding bread to the ducks is a fond pastime for many of us, reminding us of our happy childhood trips to the local park. But did you know that bread actually poses a danger to birds, as well as the environment? Eating it can cause our feathered friends to develop a condition called Angel Wing, which is when too much bread makes birds’ feathers grow too quickly. This additional weight puts a strain on their muscles, causing their wings to twist and drop open, and if not treated fast, they can lose the ability to fly.
“Angel Wing can be remedied if we reach birds before it has developed too severely,” says Caroline Simpson, a trustee of UK charity Swan Lifeline, which has rescued and treated more than 30,000 birds over the last 20 years. “Otherwise the consequence can be awful—such as amputations(截肢)of the wing.” Adult swans can also develop gut and heart disease, so it’s important we do our bit to prevent this by feeding wild birds with the right kind of food.
Bread can also cause harmful changes to the natural ecosystem. Rotting bread at the bottom of rivers and lakes allows bacteria to breed, spreading disease and attracting rats and other vermin to our waterways. It can result in algal(藻类的)blooms and the presence of a mould(霉菌)called Aspergillus too, which has the potential to kill waterfowl(水禽)and other wildlife if it gets into their lungs.
But this doesn’t mean we have to stop fun trips to feed the ducks. Giving birds the right food-like frozen peas, sweetcorn and lettuce leaves-is good for both them and the environment. So, next time you visit your local park, take a healthier alternative with you and do your bit to protect our precious wildlife.

I’m originally from Orange County, California, where I had the pleasure and honor of serving as a Newport Beach ocean lifeguard. Whenever I could, I got shifts working the Point. The Point was known for its massive rip currents(退潮流).
So, late in a shift, I was working Tower 15. Two blocks to my right was another guard named Mike, working Tower 17. He called me, “Hey, I got a couple of kids. I gotta go and give them a warning. Keep an eye on us.” I said, “Sure.”
And sure enough, as soon as he hung up the phone and grabbed his buoy(航标), a rip was snapped up under these two kids, and they were getting sucked out. All I saw was two small noses bobbing in the water. Mike was dashing toward the ocean.
By now, the mother of the two kids realized what was happening. She was screaming. I started rushing toward her, but before I was even halfway there, Mike reached the kids.
Mike swam sideways out of the rip current into the clear water and started bringing them in. When I reached their mother, Mike was in waist-deep water. The kids were so exhausted, so Mike was carrying them, one under each arm.
I turned to their mom, “Hey, it’s OK. They’re safe.” I saw her terror start to fade.
She glanced back and got her first good look at Mike. He had a number of really scary tattoos( 纹身), and his shaved head showed the scar he got from a broken beer bottle.Then a crazy thing happened. I saw a new kind of panic wash over her as though there was some new, equally dangerous threat on her kids’ lives. She rushed up to Mike and snatched her kids. Not even a thank-you.
Mike just glanced at me, shrugged, and jogged back to his tower.
If any other guard had worked at that night, including me, there would be a very real chance that that mother wasn’t going home with both her kids.

3.What information does the author want to convey in the story?

C.Don’t let fear or prejudice prevent you recognizing a hero.
