ge. The oldest and most experienced female leads the herd. It’s the leader’s
job to protect the herd.
A female will usually be ready to breed around the age of thirteen. After a twenty-two-month pregnancy, the mother gives birth to a single calf that weighs about 115 kg A female elephant will have a single baby every 4 or 5 years.
Elephants spend up to 16 hours a day eating plants. They are primarily browrs, feeding on the leaves, bark and fruits of trees and shrubs. A baby elephant starts to eat plants during the cond year. All members of the herd watch over the baby. Since the baby is too weak to travel during the first days, the herd will stay with it until it can keep up.
Young elephants are playful and love to wrestle and tumble in the mud. They learn by exploring and imitating members of their herd.
Questions:
1. Who are in charge in elephant society?
2. What’s the role of the oldest and the most experienced females?
3. Which numbers of the herd look over the baby?
4. How many babies does a mother elephant give every 4 or 5 years?
5. At what age can a baby elephant start to eat plants?
Passage 2
Bats have a reputation for being scary, but they actually do a lot of good--especially for farmers. They love to eat incts, the way you probably love cookies or ice cream. One inct that bats will swallow quickly in large quantities is the corn-eating inct,
which costs American corn and cotton growers about $2 billion a year to control and in crop loss.
A team of rearchers in Texas have been studying one kind of bat, called the Mexican free-tailed bat, that has a big appetite. According to them, a million of the bats can eat
nearly 10 tons of incts in just one night.
In early June, billions of corn-eating incts emerge along the border of Texas and Mexico. Some of them feed on cotton after feasting on southern corn, while others travel northward to swallow their way through mid-western corn, cotton, and other field crops.
Cotton and corn farmers are controlling the harmful incts mostly by spraying their crops with inct-killing chemicals. But the rearchers are looking for cheaper and more environmentally friendly ways to control the damaging incts. They think that bats could help farmers reduce the numbers of the incts chewing on their corn crop and their profits.
