文章主要介绍了科学家拯救美国加利福尼亚秃鹰的两种方法：一种是通过对电的感应的训练；另一种是将严重铅中毒的秃鹰送往洛杉矶动物园，用依地酸二钠钙（一种能溶解铅的化学物质）进行治疗。

此外，本文还提到环境对加利福尼亚秃鹰的危害以及加州秃鹰正急剧减少并濒临灭绝的状况。

21.
California condors are North America’s largest birds, with wing-length of up to 3 meters. In the 1980s, electrical lines and lead poisoning (铅中毒) nearly drove them to dying out. Now, electric shock training and medical treatment are helping to save these big birds.
In the late 1980s, the last few condors were taken from the wild to be bred (繁殖). Since 1992, there have been multiple (数量多的) reintroductions to the wild, and there are now more than 150 flying over California and nearby Arizona, Utah and Baja in Mexico.
Electrical lines have been killing them off. “As they go in to rest for the night, they just don’t see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution (电死) if they touch two lines at once.
So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-free birds died of electrocution. This has now dropped to 18%.
Lead poisoning has proved more difficult to deal with. When condors eat dead bodies of other animals containing lead, they take in large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney (肾) failures and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011. Rideout’s team thinks that the California condors’ average survival time in the wild is now just under eight years. “Although these measures are not effective forever, they are important for now,” he says. “They are truly good birds that are worth every effort we put into recovering them.”
1. California condors attract researchers’ interest because they ________.
A．are active at night B．had to be bred in the wild
C．are found on in California D．almost died out in the 1980s
2. Researchers have found electrical lines are ________.
A．blocking condors’ journey home B．big killers of California condors
C．rest places for condors at night D．used to keep condors away
3. According to Paragraph 5, lead poisoning ________.
A．makes condors too nervous to fly
B．has little effect on condors’ kidneys
C．can hardly be gotten rid of from condors’ blood
D．makes it difficult for condors to produce baby birds
4. The passage shows that ________.
A．the average survival time of condors is satisfactory
B．Rideout’s research interest lies in electric engineering
C．the efforts to protect condors have brought good results
D．researchers have found the final answers to the problem
文章大意：这是一篇说明文，文章讲述在南极洲冰块和海洋交汇的地方，生活着一种独特的小鱼。

文章分析了能让这种鱼在其它鱼无法存活的地方生活的秘密。

22. Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod (南极鳕).
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secrets. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear:Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋
白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules (分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein.
1. What is the text mainly about?
A．The ice shelf around Antarctica.
B．Protection of the Antarctic cod.
C．The terrible conditions in Antarctic.
D．A special fish living in freezing waters.
2. Why can the Antarctic cod live at the freezing temperature?
A．It loves to live in the ice-salt mixture.
B．A special protein keeps it from freezing.
C．The seawater has a temperature of -1.88℃.
D．Its blood has a temperature lower than -2.05℃.
3. What does the underlined word “it” in Paragraph 5 refer to?
A．The fish’s blood.
B．The sugar molecule.
C．A newly found protein.
D．A type of ice-salt mixture.
4. What does “glyco” in the underlined word “glycoprotein” in the last paragraph mean?
A．Sugar. B．Ice.
C．Blood. D．Molecule.

文章主要讲了一项新的研究发现，变暖的海洋减少了鱼类和贝类。

23. Finding fish is going to get harder as climate change continues to heat the world’s oceans. A new study finds that warming seas over the past 80 years have reduced the sustainable(可持续) catch of 124 species(物种) of fish and shellfish.
Overfishing（过渡捕捞) has made that decline worse, researchers say. In some parts of the world, such as the heavily fished Sea of Japan, the decrease is as high as 35 percent. That’s a loss of more than one in every three fish.
Researchers examined changes in 235 populations of fish and shellfish between 1930 and 2010. On average, that warming has caused the sustainable catch to drop by 4.1 percent, the study found. About 8 percent of the fish and shellfish populations the team studied saw losses as a result of the ocean warming. However, about 4 percent of some populations increased. That’s because certain species have thrived in warmer waters. One example is a kind of black sea fish. It lives along the northeastern U.S. coast. As warming continues, these fish will reproduce faster until they reach their limit.
About 3.2 billion people worldwide rely on seafood as a source of food. That means it’s urgent for commercial fishing fleets and regulators to consider how climate change is affecting the health of all of those fish in the sea.
1. What does the new study discover?
A．Overfishing is to blame for fish health.
B．Warming seas cause fewer fish and shellfish.
C．Seafood matters to people’s health worldwide.
D．The living regions of fish and shellfish are different.
2. What does t he underlined word “thrived” in paragraph 4 probably mean? A．Survived narrowly. B．Disappeared soon.
C．Decreased sharply. D．Developed quickly.
3. What do we know about species of fish and shellfish?
A．About 8 percent of them suffered from a great loss.
B．About 35 percent of them survived in the Sea of Japan.
C．About 3.2 billion species have been saved up to now.
D．About 80 species have died out because of warming seas.
4. From which is the text probably taken?
A．A cooking guide. B．A science magazine.
C．A news review. D．A health brochure.

文章主要介绍怎么养好宠物鱼方法。

24. How to Care for a Pet Fish
Taking care of a pet is a big responsibility, so you should make sure you learn all about your pet before bringing it home. 1 That's because fish can give them a good idea of whether or not they'll be able to take care of a more complicated (复杂的) pet later on.
First, choose what types of fish. 2 They are easier to raise and give you enough experience to take care of fish and their tanks (水箱). Some kinds of fish do not get along with others, so you'll need to choose what kinds to buy.
Next, make sure you have all of the necessary supplies. Fish need a fish tank. Make sure it is big enough for the number of fish. Fish tanks need a light and some machines to keep the water clean and at a comfortable temperature. 3
Now you can set up your aquarium (水族馆). Wash sand and decorations (装饰物) clean and fill the bottom of the tank with them. 4 Follow the instructions on the heater to heat up the water to the temperature your fish will need. Make sure your light is ready to go, too!
5 The pet store keeper can teach you how to make your fish get comfortable before you put them into your aquarium. Once the fish are in the tank, you have to watch them closely to make sure they don't get sick. Feed them in small amounts a few times a day. You will have to change some of the water at least once a week. A．Then, fill the tank with water.
B．You are ready to pick up your fish.
C．Many kids have fish as their first pet.
D．You need some beautiful tanks to change.
E．Be sure to get food for your fish as well.
F．Freshwater fish are the best fish to start with.
G．Save up your money for fish tank decorations.

trip 8 (special) for Hua Hua,” said a tourist. “We plan to stay at the base all day just to see 9 giant pandas and we plan to continue coming here even tomorrow,” he added.
Panda-related souvenirs such as headbands, dolls, school bags and decorative rings in 10 (store) at the base and in other parts of Chengdu have become popular.
十三、读写任务(书面表达)
26. In the wild, lions tend to pick on the animals that are weak, old, sick or hurt. Even with the strength of their numbers they will go after the easy prey (捕猎). The lions picked their prey of choice for this poor Gazelle. The Gazelle, surrounded by lions, looks as if she were crying when the camera closed up on her face.
The lions were faster than the Gazelle, and my goodness they were smart. When the lions got close enough to the Gazelle, even while running at speed, they would trip the running animal.
This Gazelle was moving. When pressure came from a different angle she changed directions. When she could feel the breath of the lions on her neck she changed direction. When they tried to trip her, stop her, trick her, block her, she changed direction. She ran until they stopped chasing after her. It was pointless to the lions. This Gazelle had purpose. She was running for her life.
I do not care what, who, when, where, or how often life tries to take you down a path you have not intended to go. If you feel the pressure and things are not going the way they should, change direction.
