       American black bears appear in a variety of colors despite(尽管) their name. In the eastern part, most of these bears have shiny black fur, but in the west they grow brown, red, or even yellow coats. To the north, the black bear is actually gray or white in color. Even in the same litter(胎), both brown and black furred bears may be born.
       Black bears are the smallest of all American bears, ranging in length from five to six feet, weighing from three hundred to five hundred pounds. Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears, the black bear is timid and rarely dangerous, but if attacked, most can climb trees or cover ground at great speed. When angry or frightened, they are formidable(可怕的) enemies.
       Black bears feed on leaves, roots, fruit, insects, fish, and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike squirrels and many other woodland animals, bears do not actually sleep through the winter months. Although the bear does not eat during the winter months, sustaining(维持) itself from body fat, its temperature remains almost normal, and it breathes regularly four or five times per minute.
    Most black bears live alone, except during the mating(交配) season. They prefer to live in caves. Baby black bears are born in January or February after a gestation(怀孕) period of six to nine months, and they stay with their mother until they are fully grown or about one and a half years old. Black bears can live as long as thirty years in the wild, and even longer in some nature reserves.

举一反三

   In many high schools，there are strict rules about using mobile phones. If your phone rings in class，for example，the teacher will be very angry.
   Every mobile phone has a ringtone (铃声). It tells you that someone is calling you. Now，there is a ringtone called “mosquitotone (蚊子铃声)”. Using it，students can receive calls and text messages (短信) in class but the teacher will not realize what is happening. How?
   Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older，we are unable to hear some sounds with high frequencies (频率). As a result，a child or teenager can hear the mosquitotone ringtone, but it's_inaudible_to someone 20 or older.
   But sometimes，people over 20 can hear the ringtone. One British student's phone uses mosquitotone. In class，the student's phone rang. The 32yearold teacher looked at the student and became unhappy. “I heard that. You know the rule：no mobile phone in class.”
   Not all the students are interested in mosquitotone. Jerry Jones，a high school student of 17，says，“Using mosquitotone too often is bad for our hearing. I may use it for pleasure，but not in class. It's unfair to the teachers！”
   What do parents think of mosquitotone？“I think it is perfect for places like movie theaters，” says Connie Neeson,44.“Think about it. Yon're watching a film and someone's mobile phone rings. Mosquitotone is good because many people don't hear it. However，it also has a bad influence on their study if students use it in class.”

"I used to be too heavy and have sleeping problems, and as a result I had to visit the doctor from time to time. But amazingly my situation has been greatly improved since I joined the Eating Light Club. In the club, light foods are recommended because they are foods that your body finds easy to take in and get nutrition from. I also learned to make some tasty light meals and have really got into it.

We usually think fish can't talk. But there are a lot of sounds under the ocean. In fact, scientists believe that all sea animals – at least 250,000 kinds – can "speak"! If we stay focused when diving (潜水), "we can hear animals all around us," UK scientist Steve Simpson told the BBC.

In the past years, scientists used sound recorders to hear fish's "voices". There are now thousands of recorders in the ocean. They help scientists match sounds with sea life.

A healthy coral reef (珊瑚礁) is one of the noisiest places in the ocean. Scientists can tell if it's healthy by listening to it. A healthy coral reef should be full of clicks (咔嚓声) made by shrimps (小虾). When some coral reefs died in 2015 and 2016, they became quiet. After people set up the protected areas, scientists heard the animals come back.

By listening to the ocean, scientists start to understand sea animals' languages. Strong clownfish (小丑鱼) make short "chirp(啁啾声)" sounds when going after small clownfish. A damselfish(小热带鱼) can create a pop sound to scare other fish by quickly opening and closing its mouth. Mother dolphins can use a special voice to talk to their babies. They are saying "I'm here" to comfort the baby dolphins.

Scientists are building an online library called the Global Library of Underwater Biological Sounds(全球水下生物声音库). It will collect sounds from all over the world to check sea animals' health. Humans need to understand the sounds made by underwater animals before they die out.
