The loud continuous noise of the cars or the sound of a plane can force its way into the deepest forest, yet it’s not only humans that are bothered by the noise.
Bioacoustician Bernie Krause has been studying the effect of noise pollution on wildlife, and has come across some interesting behaviors, especially among animals that communicate by vocalization（发声）, like humans. Birds use sound to communicate, but in noisy places, these animals have to shout over the natural noise to be heard.
Krause mentions a study of nightingales to clarify what he means. The birds responded to traffic noise by singing louder and louder until they actually went beyond noise pollution standards in the city. To belt out (sing loudly) their songs, they increased their lung pressure fivefold, but scientists state that this is not dangerous for the birds themselves.
Studies show that sudden noise can cause certain birds to leave their nests, exposing the young to their enemies. One study also showed that songbirds that nested close to busy motorways were much less productive than those that nested farther away. Mammals（哺乳动物）too are affected. A recent study showed that nursing caribou responded to plane noise by not producing enough milk to feed their young.
In some cases noise pollution can actually help some animals while harming others. Toads（蟾蜍）and frogs are known to vocalize in synchrony（同步；同步方式）so that no predator (their enemies) can zero in on them. Krause found that when planes flew overhead and disturbed the toad’s song, they lost their synchronicity, and it took them 45 minutes to get it back again. That gave their natural enemies plenty of time to find and catch individual toads by sound.
According to Kruse, “Not only will noise pollution bother wildlife, but it won’t help our lives either.”
1.How do young caribou suffer from aircraft noise?
A. They receive less food. B. They can’t sleep at night.
C. They are often displaced. D. They can’t hear their mothers.
2.What would happen if toads and frogs failed to sing in union?
A. They might become defenseless.
B. They would stop communicating.
C. They would soon regain their rhythm.
D. They might ne unable to hunt in groups.
3.What is the text mainly about?
A. The effects of noise pollution on wildlife.
B. The causes of noise pollution.
C. Animals’ reaction to noises.
D. The ways animals communicate with each other.

The new wave of plant-based “meat” is going mainstream and straight into one of America’s most iconic chain fast-food burgers, the White Castle Slider. White Castle announced Thursday it is introducing a vegetarian fake-meat version of its famous mini-burgers. The burgers is one of several scientifically engineered products made to make plant ingredients (成分) taste just like beef. Called the Impossible Slider, it will be first sold at 140 White Castle eateries in the New York, New Jersey and greater Chicago areas with the potential for a nationwide promotion.
The White Castle Impossible Slider---made with smoked cheddar cheese, pickles, onions and a bun---features a 2-ounce patty and costs $1.99. That compares to the chains traditional 0.9-ounce mini-cheeseburger at about 94 cents. “Plant-based proteins are growing. We felt it was a good opportunity to test it with our customers,” CEO Lisa Ingram said. “We think it will appeal to a broad range of customers---those that are meat caters who want to try something different and non-meat eaters who want this.” She also said the new sliders might bring in new customers, too.
The Impossible Slider represents what few in the traditional beef industry thought possible---that cowless meat would be a hit in a country known for its meat-and-potatoes diet and love of burgers. Plant-based meat alternatives are growing at rate of about l1% a year, according to the research firm Acosta. The market isn’t just vegetarians: Some 71% of people who buy plant-based meat also eat the real thing.
“Interest in meat alternatives seems to be driven by consumers at large, not just those looking for vegetarian lifestyles, but looking for diversification( HF1c)of tastes and health benefits,” said Billy Roberts, senior food and drink analyst at the global market research firm Mintel. “Our business is a growth business. There’ll be increased demands for products like the Impossible Burger,” Impossible Foods Chief Operating Officer David Lee said. “People are increasingly asking about what impact food has on the environment and our health.”
