I’m proud of this and wanted to learn more about our national treasure. Pandas have lived on the earth 1 at least 8 million years. Some people call 2 “living fossils (活化石)”. My chance finally came during last summer vacation. I volunteered at the Chengdu Research Base of Giant Panda Breeding and 3 close contact with pandas. When I first saw a giant panda eating bamboo with its claws, I thought 4 it must be the most lovable thing. It has a round face, big black eye patches, sharp claws and a round body. When I introduced pandas to visitors, I told them that pandas spend nearly 12 hours a day eating and they sleep in the rest of the time. 5 lucky I was! 6 baby panda was born while I was volunteering! It was amazing that the weight of the newborn panda was only 0. 1 percent of its mother’s weight—only 145 grams (克). Taking care of newborns is a very 7 task for mother pandas. As I learned more about pandas, I realized how important it was to protect them. 58 the number of pandas has increased in recent years, pandas are still endangered.

Nowadays, 3 most people still offer their seats to others, we can also find that some young people have excuses 4 offering their seats. Some drivers often call out, “Who can offer the old 5 seat?” It usually 6 work. As teenagers, what can we do? Every time an old man 7 next to me, I’ll stand up to offer my seat. After that I feel good. Perhaps someone will say you alone can’t change the society 8 . That’s right. But I do think a little thing can change the world some day. I often talk about my idea with my classmates, and they all agree with me. They think that a good environment 9 with everyone’s effort.

I’m proud of this and wanted to learn more about our national treasure. Pandas have lived on the earth 1 at least 8 million years. Some people call 2 “living fossils (活化石)”. My chance finally came during last summer vacation. I volunteered at the Chengdu Research Base of Giant Panda Breeding and 3 close contact with pandas. When I first saw a giant panda eating bamboo with its claws, I thought 4 it must be the most lovable thing. It has a round face, big black eye patches, sharp claws and a round body. When I introduced pandas to visitors, I told them that pandas spend nearly 12 hours a day eating and they sleep in the rest of the time. 5 lucky I was! 6 baby panda was born while I was volunteering! It was amazing that the weight of the newborn panda was only 0. 1 percent of its mother’s weight—only 145 grams (克). Taking care of newborns is a very 7 task for mother pandas. As I learned more about pandas, I realized how important it was to protect them. 58 the number of pandas has increased in recent years, pandas are still endangered. Let’s try our best 9 these endangered animals. Chengdu can become better and more popular, too. Then, we can say 10 , “I come from the panda’s hometown.” 1．A．for B．in C．since D．about 2．A．they B．them C．their D．themselves 3．A．have B．had C．are having D．have had 4．A．that B．what C．if D．which 5．A．How B．What C．What a D．How a 6．A．A B．An C．The D．/ 7．A．difficulty B．difficult C．difficultly D．difficulties 8．A．Because B．If C．But D．Though 9．A．help B．to help C．helping D．helps 10．A．proudful B．proudly C．proud D．prouder （7） During the 1950s and 1960s, there was a healthy social environment. If you offered your seat to 1 old or children, everyone would look up to you. At that time, being selfless, honest and serving people were good, and all people learned 2 the hero—Lei Feng. Nowadays, 3 most people still offer their seats to others, we can also find that some young people have excuses 4 offering their seats. Some drivers often call out, “Who can offer the old 5 seat?” It usually 6 work. As teenagers, what can we do? Every time an old man 7 next to me, I’ll stand up to offer my seat. After that I feel good. Perhaps someone will say you alone can’t change the society 8 . That’s right. But I do think a little thing can change the world some day. I often talk about my idea with my classmates, and they all agree with me. They think that a good environment 9 with everyone’s effort. Everyone dreams of changing the world, so let’s take action from simple acts like picking up waste, saving water, using both sides of paper.

In the future, everything 1 again. For example, when an animal dies, it becomes 2 animal’s food. Nothing is wasted. But humans have created things like plastic bags 3 can’t be broken down by nature. Our rubbish kills animals and 4 water and soil. 5 we continue making too much rubbish, the problem will only get worse. If nature can’t reuse the rubbish, we must recycle 6 . We should clean up the rubbish we’ve made because nature can’t. Recycling is also the right thing to do for another reason. The earth is rich in natural materials like water and trees, 7 these materials are not endless. We use up our natural materials much 8 than the earth is able to reproduce them. For example, each year we cut 9 more than 6,000 square miles of forest. But it takes an average of 25 years for a new tree 10 . Recycling can help us save the earth, so let’s take action right now. 1．A．use B．using C．is used D．used 2．A．another B．other C．others D．the other 3．A．who B．which C．how D．where 4．A．pollutes B．polluted C．polluting D．is polluted 5．A．When B．Whether C．Why D．If 6．A．them B．their C．it D．itself 7．A．but B．so C．and D．or 8．A．fastly B．fast C．faster D．fastest 9．A．out B．down C．in D．up 10．A．grows B．growing C．grown D．to grow （9） Australia is the largest island in the world. It is 1 smaller than China. It is in the south of the earth. Australia is big, but its population is small. The population of Australia is nearly as large as 2 of Shanghai. Enough laws (法律) have 3 to fight against pollution. The cities in Australia have got little air or water pollution. The sky is blue and the water is clean. You can clearly see fish 4 in the rivers. Plants grow very well. Last month we visited Perth, 5 city in Western Australia and went to a wild flowers exhibition. There we saw a large number of wild flowers 6 we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. In spring every year, Perth has the wild flowers’ exhibition. 7 visiting Perth, we spent a day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed 8 . Suddenly we heard bells ringing at the top of the hill. What we saw made us pick up all our things and run back to the car as quickly as we could. There were about 9 sheep coming towards us down the path. Australia is famous 10 its sheep and kangaroos. After a short drive from any town, you will find yourself in the middle of white sheep. 1．A．little B．few C．a little D．a few 2．A．that B．one C．it D．its 3．A．be made B．made C．been making D．been made 4．A．swam B．swimming C．to swim D．swims 5．A．bigger B．biggest C．the biggest D．big 6．A．where B．who C．whom D．which 7．A．Before B．Because C．As soon as D．After 8．A．we B．ours C．us D．ourselves 9．A．hundred of B．three hundreds C．three hundred D．three hundreds of 10．A．as B．for C．of D．among （10） It’s very important that we all recycle (再利用). In nature, everything 1 again. For example, when an animal dies, it becomes 2 animal’s food. Nothing is wasted. But humans have created things like plastic bags 3 can’t be broken down by nature.
