Unit 2 Wildlife Protection
一、阅读理解（本大题共4小题，共8.0分）
A
In both Africa and Asia elephants are being threatened by changes in their natural habitats. People are moving into the elephants' habitats and endangering their survival. In the country of Sri Lanka, there is one place where elephants are not only protected but also respected. It is called Elephant Transit Home(ETH).
Set up in 1995, the ETH aims to protect and care for baby elephants that are found injured or living without their mothers in the wild. Every year about 30 baby elephants in Sri Lanka need help. Many are brought to the ETH. There they are given food, shelter, and medical care. Most importantly, they are given the chance to be with other elephants and become part of a herd.
A day at the ETH begins early in the morning when the baby elephants are given their first feeding of milk. During the day, each baby will drink an average of 13 gallons of milk. Older elephants are fed mostly coconut leaves and other native plants. There are no boundaries in the area for the baby elephants as they have the freedom to walk wherever they want. The cost of caring for the baby elephants is high. The ETH spends about $125,000 each year on powdered milk for the baby elephants.
At the ETH, workers try to reduce human connections with the elephants. They also try to increase bonds(联系) between the elephants. It usually takes three years for a baby elephant to be set free into its natural habitat. The elephants are sent back to the wild together with other orphans with whom they have bonded. This program helps them return to the wild as members of a herd that will communicate with each other and take care of each other.
The ETH is considered as one of the best animal protection sites in the world. Not only are the elephants cared for, but they are treated with respect. Most importantly, they go back to live in the wild, where they belong.

一、阅读理解（本大题共4小题，共8.0分）
A
In both Africa and Asia elephants are being threatened by changes in their natural habitats. People are moving into the elephants' habitats and endangering their survival. In the country of Sri Lanka, there is one place where elephants are not only protected but also respected. It is called Elephant Transit Home(ETH).
Set up in 1995, the ETH aims to protect and care for baby elephants that are found injured or living without their mothers in the wild. Every year about 30 baby elephants in Sri Lanka need help. Many are brought to the ETH. There they are given food, shelter, and medical care. Most importantly, they are given the chance to be with other elephants and become part of a herd.
A day at the ETH begins early in the morning when the baby elephants are given their first feeding of milk. During the day, each baby will drink an average of 13 gallons of milk. Older elephants are fed mostly coconut leaves and other native plants. There are no boundaries in the area for the baby elephants as they have the freedom to walk wherever they want. The cost of caring for the baby elephants is high. The ETH spends about $125,000 each year on powdered milk for the baby elephants.
At the ETH, workers try to reduce human connections with the elephants. They also try to increase bonds(联系) between the elephants. It usually takes three years for a baby elephant to be set free into its natural habitat. The elephants are sent back to the wild together with other orphans with whom they have bonded. This program helps them return to the wild as members of a herd that will communicate with each other and take care of each other.
The ETH is considered as one of the best animal protection sites in the world. Not only are the elephants cared for, but they are treated with respect. Most importantly, they go back to live in the wild, where they belong.
