Animal moms are gr ( http: / / www.21cnjy.com )eat moms. You might be surprised at some of these moms.
Octopuses (章鱼)
The mother octopus ( http: / / www.21cnjy.com ) lays about 50,000 eggs. For about 300 days, she stays with the eggs, cleans them and protects them. She does not leave to feed. However, this animal mom dies as soon as the eggs are hatched (孵化).
Crocodiles
A crocodile mother ( http: / / www.21cnjy.com )puts a lot of time and effort into raising her babies. She starts by building a nest (巢), which she guards for over two months! When the eggs are ready to hatch, the young crocs call out to their mother, who digs them out and helps them hatch. She then carries them in her mouth down to the water, where she will guard them for several more weeks or months until they learn to hunt on their own.
Bats
Bats become moms ( http: / / www.21cnjy.com ) by hanging head up in a cave, giving birth. Catching the youngster before it can fall to the ground below, she puts it in a pouch (育儿袋). Bat moms may carry babies with them when feeding for the first few days. As the little bats get bigger and heavier, moms help them hang on the wall of their caves and return often to feed them. It continues for about three weeks, until the babies are grown up and able to fly on their own.
Koalas (考拉)
The animal mom gives birth after a pregnancy (怀孕期) of only 35 days. The hairless baby climbs into its mother’s pouch and lives there for another five months. When the little koala is between five and eight months old, it leaves the pouch for short periods of time but returns for safety. Once it is too big to return to the pouch, it will climb onto its mother’s back and ride there until it is about 12 months old.
1. Which animal moms die when their babies are born
A. Octopuses. B. Crocodiles. C. Bats. D. Koalas.

A. in her mouth ( http: / / www.21cnjy.com ) B. on her back C. in her pouch D. by her tail

3. 提高题（C组题）阅读理解
Elephants might ( http: / / www.21cnjy.com )be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That’s why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.
Years ago, overhu ( http: / / www.21cnjy.com )nting and the ivory trade were the biggest threats to elephants’ survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.
The 21st cen ( http: / / www.21cnjy.com )tury brings a different challenge to elephant conservation — land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.
Successful conservati ( http: / / www.21cnjy.com )on strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.
AWF researchers ar ( http: / / www.21cnjy.com )e searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.
The AWF is helping e ( http: / / www.21cnjy.com )lephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.
1). The first paragraph of the text is mainly to tell readers _____.
A. African elephants are endangered now
B. there remains a lot to do to protect African elephants
C. African elephants are popular animals
D. the number of African elephants has increased over the years
2). What is the bigges ( http: / / www.21cnjy.com )t difficulty in protecting African elephants now
A. They are still b ( http: / / www.21cnjy.com )eing killed. B. Their habitats are being destroyed.
C. They don’ ( http: / / www.21cnjy.com )t have enough food. D. They can’t live in peace with farmers.
3). To protect elep ( http: / / www.21cnjy.com )hants, the AWF does all the following EXCEPT _____.
A. keeping elephants B. protecting elephants’ habitats
C. doing resea ( http: / / www.21cnjy.com )rch on elephants D. helping farmers improve their life

3. 提高题 阅读理解（C组题）
Animal moms are gr ( http: / / www.21cnjy.com )eat moms. You might be surprised at some of these moms.
Octopuses (章鱼)
The mother octopus ( http: / / www.21cnjy.com ) lays about 50,000 eggs. For about 300 days, she stays with the eggs, cleans them and protects them. She does not leave to feed. However, this animal mom dies as soon as the eggs are hatched (孵化).
Crocodiles
A crocodile mother ( http: / / www.21cnjy.com )puts a lot of time and effort into raising her babies. She starts by building a nest (巢), which she guards for over two months! When the eggs are ready to hatch, the young crocs call out to their mother, who digs them out and helps them hatch. She then carries them in her mouth down to the water, where she will guard them for several more weeks or months until they learn to hunt on their own.
Bats
Bats become moms ( http: / / www.21cnjy.com ) by hanging head up in a cave, giving birth. Catching the youngster before it can fall to the ground below, she puts it in a pouch (育儿袋). Bat moms may carry babies with them when feeding for the first few days. As the little bats get bigger and heavier, moms help them hang on the wall of their caves and return often to feed them. It continues for about three weeks, until the babies are grown up and able to fly on their own.
Koalas (考拉)
The animal mom gives birth after a pregnancy (怀孕期) of only 35 days. The hairless baby climbs into its mother’s pouch and lives there for another five months. When the little koala is between five and eight months old, it leaves the pouch for short periods of time but returns for safety. Once it is too big to return to the pouch, it will climb onto its mother’s back and ride there until it is about 12 months old.
1. Which animal moms die when their babies are born

Elephants might ( http: / / www.21cnjy.com )be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That’s why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.
Years ago, overhu ( http: / / www.21cnjy.com )nting and the ivory trade were the biggest threats to elephants’ survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.
The 21st cen ( http: / / www.21cnjy.com )tury brings a different challenge to elephant conservation — land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.
Successful conservati ( http: / / www.21cnjy.com )on strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.
AWF researchers ar ( http: / / www.21cnjy.com )e searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.
