1 . 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式.

Nearly one billion animals died in the Australian bushfires. That number would have been even     1    (large) if it had not been for wombats(袋熊). When the fires started, their underground homes     2    (become) places of shelter for many other lives.

Wombats are small, furry mammals native to Australia. There are three wombat species. Northern and southern wombats have furry noses,     3     common wombats have bare skin on noses. You shouldn’t let the     4    (appear) of wombats fool you, though. Despite their size, they are     5    (unbelievable) fast. They can run at the speed of an Olympic runner, but only for a minute and a half or so.     6     is interesting is their cube-shaped poop(粪便). They often pile up their poop     7     a way to mark their areas. Scientists believe the square shape     8    (form) to stop the poop from rolling away.

Now there are only about 500 northern wombats     9    (survive) in the wild. The species is considered to be critically endangered. Luckily, conservationists are attempting     10    (help). In the 1980s, just 35 northern wombats were left alive — so things are improving!

2 . Yosemite is a national park in California. It is very beautiful and big. The park includes more than 760,000 acres in the California Mountains. Most of the park is wilderness.

The part of Yosemite that everyone likes is Yosemite Valley. It is a tiny valley that is 7 miles long and less than 1 mile wide. It has tall rock walls and streams that splash down in waterfalls. More than two million visitors come to the valley each year.

One ranger (守护人) says the number of visitors is more than the land can handle. The valley has 4,500 camping spots. It has a hotel that can hold 4, 000 families. This is still not enough to handle all of the visitors. The valley has grown so big that it has a lot of traffic and crime.

A worker says the park is trying to keep the beauty of the park and let everyone visit. Some areas have been fenced off from people and planted with seeds to try to keep them beautiful.

A former worker thinks Yosemite should get more money to take better care of the park. He would also like to teach people what the park service is trying to do.

Some people are trying to save Yosemite Valley. A plan has been made to get rid of some buildings. There will be fewer cars allowed inside the park. More buses will help get people around.

3 . My brother belongs to a strange group known as birders. Together with his three friends who are likewise into the hobby of birding, they march on landfills, and hike through the wooded lands, each of them armed with a pair of binoculars (双筒望远镜), a digital camera, biscuits, and water. One of them carries a telescope which comes in handy in case they want to take a look at a bird up close.

Understandably, their clothing is light; their shoes are designed for comfort, and they never fail to bring with them hats. Moving at a slow pace, they go in search of birds. And, yes, they carry a field guide --- a manual for identifying birds.

It is interesting to note how my brother and his co-birders go through their hobby: first, they look for a bird (either with the naked eyes or with the help of their binoculars); when they find one, they identify it; they then write it down. In case they are unable to determine the bird’s identity, they search for it in the field guide. If the bird is not in the handbook, they take down notes, make a rough drawing representing the chief features of the bird, or even take a picture of it to be used as a future reference.

A device, called the National Geographic’s Handheld Birds Personal Digital Assistant, is available for those who plan to take up birding in North America. This handy device is a digital field guide containing more than one thousand five hundred visual representations of birds. It has a searchable database of over eight hundred North American bird species.

For those seriously considering birding as a hobby but having second thoughts for fear of catching the terrible bird flu, it is important to know that you can take up the hobby and be safe from the fatal disease if you strictly observe the slogan of birders worldwide: just watch, don’t catch.

4 . Do dogs understand us?
Be careful what you say around your dog．It might understand more than you think．
A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany．The dog also appears to be able to learn new words as easily as a 3-year-old child．Its word-learning skills are as good as those of a parrot or chimpanzee．
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects．Then the owner told the dog to go and fetch one of the items and bring it back．In four tests, Rico got 37 out of 40 commands right．As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words．
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew．The owner then told Rico to fetch the object, using a word the dog had never heard before．
The correct object was chosen in seven out of ten tests, suggesting that the dog had worked
out the answer by process of elimination（排除法）．A month later, Rico remembered half of the new names, which is even more impressive．
Rico is thought to be smarter than the average dog．For one thing, Rico is a border collie, a breed （品种）known for its mental abilities．In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months．
It's hard to know if all dogs understand at least some of the words we say．Even if they do, they can't talk back．Still, it wouldn't hurt to sweet-talk your dog every now and then．You might just get a big, wet kiss in return!

5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Many people keep small fish    1     pets. They keep them in a tank of water. The tank is made of glass. People can look     2     it. They can see inside the tank and watch the fish.

The fish need room. They mustn't be crowded. They need air     3     (breathe). There must be enough water for all the fish. So the size of the tank is very     4     (importance)．

In the tank people put small plants     5     are good for fish. They give oxygen to the water. Plants help in other ways, too. They can hide behind the plants and sleep, lay     6     (egg) there.

The fish must     7     (keep) in water all the time. Some fish can jump high. So the tank should be covered. This keeps the fish from     8     (jump) out.

The fish need food and should be fed every day. But     9     you give them too much food, it is very bad, for the extra food will fall to the bottom and make the water dirty. So the fish should get just enough food and finish     10     in ten minutes. Nothing should be left.

6 . I've come back to check on a baby. Just after dusk I'm in a car down a muddy road in the rain, past rows of shackled (戴镣的) elephants, their trunks swinging. I was here five hours before, when the sun was high and hot and tourists were on elephants' backs.

Walking now, I can barely see the path in the glow of my phone's flashlight. When the wooden fence post stops me short, I point my light down and follow a current of rainwater across the concrete floor until it washes up against three large, gray feet. A fourth foot twisted above the surface, tied tightly by a short chain and choked by ring of metal spikes(尖刺). When the elephant tires and puts her foot down, the spikes press deeper into her ankle.

Meena is four years and two months old, still a child as elephants go. Khammon Kongkhaw, her caretaker, told me earlier that Meena wears the spiked chain because she tends to kick. Kongkhaw has been responsible for Meena here at Mactaman Elephant Adventure, near Chiang Mai, in northern Thailand, since she was 11 months old. He said he keeps her on the spiked chain only during the day and takes it off at night. But it's night now.

I ask Jin Laoshen, the Mactaman worker accompanying me on this nighttime visit, why her chain is still on. He says he doesn't know.

Mactaman is one of many animal attractions in and around tourist-crowded Chiang Mai. Meena's life is set to follow the same track as many of the roughly 3,800 captive(被捕获的) elephants in Thailand. When Meena is too old or sick to give rides -- maybe at 55, maybe at 75 she'll die. If she's lucky, She will get a few years of retirement. She'll spend most of her life on a chain.

D．to tell the reason why the number of elephants is decreasing

7 . As wildfires continued to sweep across Australia, the loss of life in the area was reaching astonishing numbers. Ecologists (生态学家) at the University of Sydney said that nearly half a billion animals and plants had been wiped out since the fires began several months before. Images and videos from the area showed kangaroos trying to escape from burning forests and charred (烧焦的) bodies of koalas lying on the ground.

Koalas had been already under threat because of significant habitat loss, and they were hit particularly hard compared with other animals. Ecologists said nearly 8,000 koalas—about one-third of the population in their primary habitat—were believed to have died from the big fires. Professor Dieter Hochuli from the University of Sydney said it wasn’t just the well-known species, such as kangaroos, koalas and emus (鸸鹋), that were in danger. Insects also suffered losses. Additionally, many rare plant species might have disappeared completely.

While animal hospitals were taking in as many animals as possible to treat burns and nursed them back to health, services had overall struggled to keep up with the amount of care needed. And the animals that had survived would have trouble finding food and shelters in the ongoing fire, so they were still in a dangerous situation.

“We’re getting a lot of lessons out of this and it’s just showing how unprepared we are,” Dr. Sussan Ley said. “Now Australia is burning and national parks and our native animals are being destroyed. People have lost homes. People have died. Firefighters have been killed defending communities, most recently last night. There’s no plan in place even wildlife carers don’t have plan for when they can go in after fire.

A．To explain why there were so many rare animals in Australia.

B．To show the terrible effect Australian wildfires had on species.

C．To further confirm Professor Dieter Hochuli’s unique opinion.

D．To warn people to take good care of wild animals and plants.

2. Why were the animals still in danger after surviving the fire?

A．They failed to recover from serious burns.	B．They might be hunted by people for food.
C．They were short of food and shelters.	D．They were unable to get nursing services.

3. What is the main idea of the text?

A．Many rare animal species might have disappeared.

B．Measures should be taken to prevent Australian wildfires.

C．Australian wildfires killed nearly half a billion animals and plants.

D．Ecologists have made great efforts to find the causes of wildfires.

8 . Penguins (企鹅) are birds that “fly” underwater. By flapping (拍打) their wings the same way birds do in the air, penguins can move through the water well.

    1    Most birds have hollow (中空的) bones that help make flying easier. But the penguin’s bones are heavy. This helps them stay underwater.

    2    They feed on many different kinds of fish.

    3    Some live in Antarctic, one of the coldest places on Earth. Others live on the Galapagos Islands, a very hot place.     4    People and penguins eat some of the same foods. The more fish people take out of the sea, the fewer there are for the penguins to eat.     5    

A．Penguins are very tough (坚强的) birds.

B．Penguins find it hard to adjust.

C．All penguins hunt for food underwater.

D．Penguins are different from other birds.

E．Ocean pollution is a real problem for penguins.

F．People, though, are the penguin’s biggest problem.

G．Also, penguins sometimes get caught up in fishing nets and die.

9 . It is the year 3000. I come to a place where I can’t see any water, plants or animals but black clouds in the sky and sand everywhere. It’s very dry so I drink some water that I carry with me. A native sees what I do and asks “What is it?” I pour some water and tell him it’s called water. “Oh, I’m so lucky that I can see water!” the man shouts in an excited voice. “You have never seen water? But how can you live without water?” I ask.

“Harry, get up, it is 7 o'clock, or you will be late!” a voice comes to my ears. “Oh! What a strange dream I dreamed just now!”

In class, I always think of that dream. And I also think of the fresh air, clean water, blue sky, green plants and animals in our world nowadays. How beautiful our life is!

But in order to make more money, people have built more and more factories. These factories send out waste smoke and water with chemicals which are harmful to the environment. The pollution is becoming worse and worse, and as a result, some animals and plants die out. With the development of agriculture, farmers spray aerosol (喷雾) and fertilizer, which also pollute the water and air. In the street the cars and buses are sending out heavy smoke which pollutes the air badly. Even tourism is harmful to the environment. When some tourists travel somewhere, they throw the plastic bags and rubbish onto the ground.

These behaviors are polluting the environment and the environment will become the greatest problem of the world. We shouldn’t pollute the environment any more. Otherwise more and more animals and plants will disappear. And maybe my dream will come true in the future.
