C Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ C Yushu in Qinghai is a home for black-necked cranes(黑颈鹤).These cranes travel very far every year.They spend about 5 months on the Qinghai-Xizang Plateau(高原). In March,black-necked cranes will start flying back to Qinghai.Lakes and marshes(湿地) are perfect for them.Although they may fly to other places like forests sometimes,they always come back to the plateau areas. Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ Life for black-necked cranes is tough as they do not have enough food and the weather changes a lot.Black-necked cranes have a very small population and our country is trying to save them all the time.People in Yushu love these cranes very much.In their tradition,the black-necked cranes are a symbol of good luck.It makes them very popular there. Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ In fact,getting on well with wild animals is not that difficult.We just need to give them a bit more space to live in.People in Yushu are just like that.They are working to help the black-necked cranes live better and make sure these beautiful cranes return to Qinghai every year.

C Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ D Have you ever thought about this?When you sit down and begin to eat a tomato,suddenly,the tomato starts to “scream(尖叫)”!Of course,this thing would never really happen.But a new study shows that plants make sounds when they are in pain(痛苦).Scientists in Israel have done the study.They use ultrasonic microphones(超声波麦克风) to record the sounds of tomato plants in boxes. Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ Scientists listen to three groups of plants.The first two groups make sounds 30 to 50 times every hour.The third group only makes sounds once every hour.“When tomatoes are not in pain at all,they are very quiet,” Lilach Hadany from the study team tells readers.The highest sound humans can hear is about 16 kilohertz(千赫兹).The plants’ sounds are too high for us to hear (about 40-80 kilohertz). Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ Scientists believe that animals and insects may listen to the sounds.For example,the sounds can tell them that the plant is in pain and not good for laying eggs on.When an animal wants to eat plants,it can also use the sounds to choose which one to eat. Scientists also listen to other plants such as wheat and corn.They also make more sounds when they are in pain.Scientists say the study can help farmers in the future.They can better take care of the crops by “hearing” how plants feel. Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ( )66.When may tomatoes make sounds more often? A.When we put them in the sun. B.When we water them. C.When we cut off parts of them.

C.When scientists begin the study. D.Who listens to these sounds. D Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ( )68.Which is the best title for the text? A.Scientists Studying in Fields B.Plants “Crying” in Pain C.Animals Talking with Plants D.Farmers Planting with Science B Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ E The Amazon rainforest is the world’s largest rainforest.But a study shows it may become grassland in a few years.Climate change and human activities make it “sick”.Usually,the rainforest can fix itself.But now,it feels too “tired” to get better. Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ Why is the Amazon rainforest “sick”? The Amazon rainforest is one of the world’s wettest places.Since 2005,there have been three droughts in the rainforest.They were caused by climate change.The trees don’t have enough water to grow.What’s worse,as they become dry,they can easily catch fire. Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ On top of this,people cut down rainforest trees for wood.They burn the forest to make farmland.They clear(清理) trees to find minerals(矿产).All these activities have caused about 17% of the rainforest to disappear. Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ What will happen if we lose it? The Amazon rainforest is like the lungs(肺) of our planet.The rich plants take CO2 out of the air and make O2.They make about 20% of the planet’s O2.If the Amazon rainforest “dies”,there will be more CO2 and our earth will become even hotter. The Amazon rainforest is also home to over 3 million animals and plants.Many of them can’t live anywhere else.Perhaps they would disappear. Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ( )69.What does the study show? A.The Amazon rainforest was once grassland. B.Rainforests can speed up climate change.

A.①② B.②③ C.③④ D.①④ D Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ( )71.Why is the Amazon rainforest called “the lungs of the earth”? A.Because it makes about 20% of the earth’s O2. B.Because it has 17% of the earth’s minerals. C.Because the air there is the freshest and the cleanest. D.Because it’s the coolest place on the earth. A Ⅷ -- Unit 4　单元练习 Ⅰ Ⅱ Ⅲ Ⅳ Ⅴ Ⅵ Ⅶ Ⅷ Ⅸ Ⅹ ( )72.What will happen if the Amazon rainforest “dies”? A.The earth will have more animals and plants. B.The earth will become colder.
