Passenger pigeons(旅鸽)once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群)so large that they darkened the sky for hours.

It was calculated that when its population reach its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant birds in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.

Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.

By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered(驱散)the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.

In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden in September 1, 1914.

Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)-either recorded or real-may even prevent elephants from damaging farmer's crops.

In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.

From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

One night, when I was eight , my mother gently asked me a question I would never forget. “Sweetie, my company wants to me but needs me to work in Brazil. This is like your teacher telling that you’ve done and allowing you to skip a grade(跳级), but you’ll have to your friends. Would you say yes to your teacher?” She gave me a hug and asked me to think about it. I was puzzled. The question kept me for the rest of the night I had said “yes” but for the first time, I realized the decisions adults had to make.

It was then I started to appreciate the tough choices she had to make on family and work. difficult decisions, she used to tell me, you wouldn’t know whether you make the right choice, but you could always make the best out of the situation, with passion and a attitude.

Back home , I myself that what my mother could do, I could, too. If she to live in Rio all by herself, I, too, could learn to be . I learn how to take care of myself and set high but achievable .

My mother is now back with us. But I will never forget what the has really taught me. Sacrifices in the end. The separation between us has proved to be for me.
