  Researchers at San Diego Zoo have been studying what has been described as the “secret language” of elephants.They have been monitoring communications between animals that cannot be heard by human ears.

  The elephant's call will be familiar to most people, but the animals also give out growls(低吼).Their growls, however, are only partly audible(听得见的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing.To learn more about the inaudible part of the growl, the team attached(附在……上面)a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo's female elephants.The researchers could then relate the noises the animals were making to what they were doing.Matt Anderson, who led the project, told BBC News, “We’re excited to learn how they interact and contact with one another.”

  The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation(妊娠期)of over two years, in the last 12 days we see the low part of the growl, which we can't hear.This we believe is to announce to the rest of the herd that the baby is upcoming, ” said Dr Anderson.

  The researchers believe that this also warns the elephants to look out for coming danger.“You may think that a baby calf of about 300 pounds would not be as open to predation(捕食)as other species, ” he says.“But packs of hyenas(袋狼)are a big threat in the wild.”

  Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away.

READING COMPREHENSION

  To help the environment, many Americans have made the change from paper and plastic bags to reusable grocery bags.But a report by a Florida newspaper says that reusable grocery bags sold by some supermarkets contain high levels of lead(铅).Lead is a metal that can be harmful to humans, especially young children, Now, Senator Charles Schumer is asking the US government to investigate(调查)the use of lead in reusable shopping bags.

  “When our families go to the grocery store looking for safe and healthy foods to feed their kids, the last thing they should have to worry about is poisonous bags.”Schumer said,“A quick investigation will allow everyone to make informed, timely decisions.”Schumer added.

  Lead in the bags is not likely to rub off(因摩擦而粘在……上面)on food.But over time, paint on the bags can chip and the bags can wear out.When this happens, lead can be released(释放).

  The Tampa Tribune newspaper said certain bags sold at Publix and Winn-Dixie supermarkets had lead levels that were a concern to health officials.The affected bags were found in Florida.But Publix has more than 1,000 stores in Alabama, Florida, Georgia, Sough Carolina and Tennessee.Publix says that all of its bags are under current laws about lead content, but that they have asked the makers of the bags to reduce the lead levels in the product.

  The bags with the highest levels of lead had fancy designs and many pictures.Plain reusable bags without decoration were found to contain little lead.Consumers worried about lead levels in reusable bags can change to cloth or string bags.Paper bags are also a good choice, since paper can be recycled(回收).

  Since 2007, Publix supermarkets have sold more than 13 million reusable bags.The store says because shoppers have made the change to reusable bags, it has saved more than 1 billion paper and plastics bags.

[  ]

A.

reusable bags do little harm to kids' health

people have shown much concern for the reusable bags

C.

people will be informed of the facts about the reusable bags

D.

(3)

It can be inferred from the text that Publix might believe that the bags they sold are ________.

[  ]

A.

dependable

B.

convenient

C.

harmful

D.

popular

(4)
