听力原文： About 25 million children in developing countries have no homes. So they live on city streets. Another 75 million children live at home but work on the streets. United Nations Children's Fund says most of these children do not receive education or health care. The private organization known as "Child Hope U. S. A." is trying to do something to help these children. The group has many goals. Child Hope U. S. A. wants to halt the spread of AIDS and the use of illegal drugs among children. It wants to protect young girls from being mistreated sexually. It wants to teach children how to protect themselves, how to survive conditions on the streets and how to feel good about themselves. Child Hope U. S. A. is trying to establish educational programs for the children. It is working with local groups to get their help in protecting the rights of street children. And, it is trying to make international development groups more informed about street children. Some children begin living on the streets when they are five years old or younger. Four-year-old can be found selling goods on the street corner or begging for food and money. Some of these children have lost their families because of wars or natural disasters, such as earthquakes and floods. Some are helping their families earn enough money to survive. Studies show that more than one million children live and work on the streets in the Philippines. Seven million children live on the streets in Brazil. About 250 thousand children live on the streets in Mexico. About ten million Mexican children work on the streets. Child Hope U. S. A. works closely with international children's groups, government agencies and other national and local groups. It has offices in Brazil, Guatemala, the Philippines, Britain, Canada and the United States. Child Hope U. S. A. also works to improve child labor laws. In 1992, Pakistan approved new laws to control child labor. The laws make it illegal for companies to lend money to families and let children repay the loan by working in factories. Yet, about eight million children still are working in Pakistan to repay loans. We will talk more about the problems of children in developing countries next week.

听力原文： Why are so few tigers man-eaters？ Why are fewer than three percent likely to be man-eaters？ Why are we off the menu for tigers？
It's widely assumed that tigers keep us off the menu through fear. But what are they afraid of？ Do they know that we may be better armed than they are？ Can they really realize that if they kill just one of us they'll get a whole army after them？ Do they find our smell unpleasant？ Perhaps.
I think the explanation is simpler and, in a way, more interesting. I suspect that a tiger's fear of humans lies in the way he perceives us at the unique moment of contact.
I am 1.8m tall. A tiger is less than lm tall but may be up to 3m long. So when a tiger sees me, it might reasonably assume that I'm 6m long. If I were a huge deer, he'd leap on my back, but he discovers I have no back. From the front I'm huge, but from the side I all but disappear very upset. A hunter has to be confident that it can tackle its prey, and no one's confident when upset.
If I'm correct, the opposite should be tree of a sitting human, who is half the size, presents twice the spread of back and more closely resembles a medium-sized deer. And, indeed, many attacks on people involve villagers sitting or bending over to cut grass.
When that tiger appeared within inches of me on that twilight evening, I know what was going through my mind. But perhaps I should not even try to guess what he was thinking.
