On my recent trip to Sydney with my parents, we visited the Wildlife Park.
The Wildlife Park has lots of different animals and birds. Some are native (当地的) toAustralia and can only be found there. There are over 600 animals there, including kangaroos,koalas and crocodiles (鳄鱼). They are kept in their natural environment.

There was also a bird show. The keepers showed us different species (种类) they had. I saw an old parrot which could “talk”. It made a great impression on me.

What do the following animals have in common (相同) Pandas, tigers, whales, lions and camels They are all in danger!
Animals are in danger for many reasons. Sadly, humans are behind them! Here are three reasons.
Excessive hunting (过度猎杀): For centuries, humans have hunted elephants for their tusks, killed tigers for their fur, and caught many other animals for meat.
Foreign animals: In 1505, Europeans discovered a beautiful island in the Indian Ocean named Mauritius. They brought dogs, pigs, monkeys, and rats with them. It was bad news for dodo birds. They did not have any natural enemies before. They picked up fruits falling down from trees and built their houses on the ground. Shortly after humans came, however, dodo birds were in big trouble — man killed them for their meat, and those animals broke their homes and ate their eggs. The dodo birds first became rare and then extinct. The last dodo bird was killed in 1681.
Loss of homes: We cut down forest for farming. We cut down trees to build houses. We build dams to make sure that we have enough water to use. When we are trying to make our lives comfortable, the land for animals to live on becomes less and less.

63．(c)hallenge
【详解】句意：我们面对困难的时候应该挑战自我。根据“in the face of difficulties”和首字母可知要挑战自己，challenge动词，“挑战”，should是情态动词，后面用动词原形。故填(c)hallenge。

68．tourists
【详解】句意：北京每年有很多游客。tour意为“旅游”，tourist意为“游客”。分析句子结构可知，本句是there be句型，there be +人或物+地点。表示“某地有某人或某物”。结合句意可知，“tourist游客”符合语境。空前有单词“many许多的”，所以tourist用复数形式tourists。故填tourists。

71．例文：
Dear Jack,
How are you doing Let me tell you something about protecting pandas in China.
Firstly, we choose some places as nature reserves for pandas. We protect pandas in these areas. Then when young pandas grow up, we teach them necessary skills to live in the wild on their own. After they learn as much as possible, we set them free into the forests to live a normal life. We also try to get help from international organizations, such as the WWF. They can give us a lot of knowledge about endangered animals.
Welcome to China to see the pandas.
Best wishes!
Yours,
Li Lei
