1 . In Canada, you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends.

Before they keep them in their houses, they take them to animal hospitals to give them injections (注射) so that they won’t carry disease. They have special animal food stores, though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people’s houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against killing wild animals. If you killed an animal, you would be punished. If an animal happened to get run over by a car, people would be very sad.

People in Canada have many reasons to like animals. One of them might be: Their family ties are not as close as ours. When children grow up, they leave their parents and start their own life. Then the old will feel lonely. But pets can solve this problem. They can be good friends and never leave them alone.

1. The passage mainly talks about ________.

A．the pets are sick	B．the pets are wild
C．they want to stop them from carrying disease	D．they want them to sleep on the way home

3. This passage shows that Canadians ________.

A．hate animals

B．often kill animals

C．love animals

D．don’t keep pets inside houses

4. In Canada, children leave their parents when they grow up because ________

A．they don’t love their parents any more	B．they can only find jobs far from their parents
C．their parents’ houses are too small	D．they wouldn’t depend on their parents any more

2 . Scientists say baby sharks are at risk of being born smaller and without the energy they need to survive because of warming oceans from climate change.

Scientists studied epaulette sharks, which live off Australia and New Guinea. They found that warmer conditions expedite the sharks’ growing process. That meant the sharks were born earlier and very tired. The findings could be used in the study of other sharks, including those that give birth to live young.

The scientists studied 27 sharks. Some were raised in average summer water temperatures, about27 degrees Celsius. Others were raised in higher temperatures around 29 degrees Celsius and 31 degrees Celsius. They found that the sharks raised in the warmest temperatures weighed much less than those raised in average temperatures. They also showed reduced energy levels.

Epaulette sharks can grow to a length of about one meter. Their name comes from large spots on their bodies that look like decorations on some military clothing.

One study this year found that worldwide numbers of oceanic sharks and rays dropped more than70 percent between 1970 and 2018. Overfishing is a main concern, while climate change and pollution also threaten sharks.

Carolyn Wheeler is a doctoral student at the University of Massachusetts Boston and with the ARC Centre of Excellence for Coral Reef Studies at James Cook University in Australia. She is the lead author of the epaulette shark study. She said that while all the sharks survived, those raised in warmer temperatures were not strong enough to survive for long in the wild.

She added that if the sharks are born smaller than usual, they are probably going to have to start looking for food sooner, and they’re going to have less time to adjust to their surroundings.

The study should serve as a warning to ocean governing agencies that careful management is needed to prevent the loss of more sharks.

5 . In habitats across the planet, animals periodically drop everything to walk, fly or swim to a new place. Some animals such as whales and geese learn migration paths by following their parents. Others, including small songbirds, gain the distance and direction of their migration within their genetic code. And some animals use a combination of genetics and culture to guide their migration.

Another group of migrators does not quite fit either model, and researchers have only recently started to figure out how they find their way. The Cory’s shearwater is an oceangoing seabird that migrates over the Atlantic every year. The young do not migrate with their parents, so culture cannot explain their journeys. And the exact paths vary wildly from individual to individual, making genetics equally unlikely.

Cory’s shearwaters are long-lived, rarely producing young successfully before age nine. This leaves an opening for learning and practice to develop their migration patterns. Researchers call this the “exploration-refinement”, and until now it has been hypothetical (假设的) because of difficulties in tracking migratory animals’ movements.

But a team of researchers has done that by attaching small geolocators to more than 150 of the birds aged four to nine. They found that younger birds traveled longer distances, for longer periods, and had more diverse paths than older birds. “We finally have evidence of the ‘exploration-refinement’ for migratory birds,” says Letizia Campioni, who led the study. Younger Cory’s shearwaters are able to fly just as fast as the adults——but they do not, suggesting that the young do more exploring, which gradually fades as they mature and settle into a preferred course.

“Although it may seem less efficient than other strategies, exploration refinement could be beneficial to birds and other organisms in a rapidly changing world due to unpredictable man-made changes,” says Barbara Frei. “It might be safer to repeat a behavior that was recently successful than to rely on patterns that were perfected long ago but might no longer be safe.”

1. What is the first paragraph mainly about?

A．It describes animals’ habitats.	B．It compares different species.
C．It talks about migration models.	D．It introduces a tracking technology.

2. What does the underlined word “this” in Paragraph 3 refer to?

A．The opening for learning and practice.

B．The unique living habit of Cory’s shearwaters.

C．The process scientists track Cory’s shearwaters’ movements.

D．The way Cory’s shearwaters form their migration patterns.

3. What does Letizia’s study find about the younger Cory’s shearwaters?

A．They travel as much as adult birds.	B．They lower the speed for exploration.
C．They move in a predictable manner.	D．They look for a course with their parents.

4. What can we conclude from the last paragraph?

A．Exploration refinement contributes to birds’ adaptability.

B．Man-made changes make migration easier.

C．Animals make a safer journey via a fixed track.

D．A combination of strategies assures migration success

7 . The success of many North American crops partly depends on ground beetles, small insects that eat pests and weed seeds that could otherwise damage crops. But a new study by researchers in the US and Canada suggests not all of the nearly 2,000 species of ground beetles found in North America will survive climate change. Some could decline. And that could have a far-reaching impact on agriculture, forestry, and conservation.

By studying the data on 136 different ground beetle species across continental   North America, Puerto Rico and Hawaii, the researchers found that a species’ chance of success in a changing climate depends on several important factors, such as its habitat preference, body size, and whether it flies, climbs or runs.

“We found that less mobile, nonflying ground beetles, which are critical pest control agents, are more likely to decline over time in a warmer, dryer climate,”   said Tong Qiu, who led the study.   “That means you’re going to have more pests that can impact agricultural and forest ecosystems.” But there is reason for hope, Qiu added, because the analysis also showed that habitat conservation can lessen these effects and reverse the trends in some areas.

“We hope conservation biologists will use this information and the online map that we created to better manage habitats for insects in general. Ground beetles are very beneficial to ecosystems, but they’re largely invisible to the average person. In this paper we’re showing the broad impacts they have on whole communities in forested and agricultural ecosystems,” said Qiu.

The researchers used ground beetle   count data from the National Science   Foundation’s National Ecological Observatory Network (NEON) and from 11previously published studies to measure and map the beetles’ distribution across   North America. Habitat information, such as the location of gaps in forest canopies and the density of plants on a forest floor, was obtained by using NEON’s imaging instruments to create detailed thrẹe-dimensional images of landscapes. They then entered the data collected into a computer model to simulate (模拟) climate changes to study how the insects would respond.

1. What does the new study in North America show?

A．Pests could des troy many North American crops.

B．Some ground beetles will not survive a climate change.

C．The survival of ground beetles only depends on its habitat.

D．Some ground beetles will destroy crops in a warmer climate.

2. What does Tong Qiu intend to convey in paragraphs 3 and 4?

A．There is no way to stop the decline of ground beetles.

B．Critical pests are more adaptable in a warmer, drier climate.

C．Ground beetles will become less mobile in a warmer climate.

D．The importance of ground beetles should be widely recognized.

3. How did the research team carry out the study?

A．By analyzing data.

B．By assessing statistics.

C．By doing field research.

D．By studying documents.

4. What is the best title for the passage?

A．North American Agriculture Crops at Risk

B．Crop-saving Beetles under Climate Threat

C．A Catastrophic Climate Change on the Way

D．Beetles’ Reaction to simulate Climate Changes

8 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

A Four-legged Guardian Angel

Snow had just melted off the ground that April day at our house in Regina Beach. I had just cleaned up the pool in preparation for selling the house. The year before, I had lost my job, and now our financial situation was depressing. Finally, I had put the home on the market. Even worse, I would have to give up my beloved Great Dane (大丹犬), Brigitte, because I could no longer afford the cost of feeding it. The thought of losing the dog and our beautiful home was almost more than I could bear.

Deep in discouragement, I sat typing up my application letters. Out of the corner of my eye I could see my thirteen-month-old son, Forrest, as he lay on the carpet, playing near our big, gentle Brigitte. It seemed as if Brigitte was always meant to be in this family and she turned out to be a perfect companion.

Brigitte came to our house on Christmas eve when the doorbell rang and I was sure some of my Christmas packages had arrived.   I ran to the door but no one was there. I sensed something and looked down, only to find a beautiful Great Dane sitting there, looking up at me with big, intelligent eyes. Perhaps, someone had found the puppy somewhere and left her there, and then rang the doorbell and ran away. They accurately guessed I would welcome an additional family member and take care of her.

Thinking of these, I couldn’t help sighing and went straight back to work. However, I hadn’t typed more than two sentences when Brigitte began barking and running back and forth to the sliding glass door overlooking our pool.

I raced to see what was happening and noticed that the sliding door was slightly open. Suddenly, I realized Forrest was nowhere to be seen.   In panic, I opened the door and ran outside.

注意：
1. 所续写短文的词数应为150左右；
2. 请按如下格式在答题卡相应位置作答。

There I was surprised to see Brigitte, who was terrified of water, dive into the pool.
