1 . Endangered polar bears are breeding (繁殖) with grizzly bears (灰熊), creating “pizzly” bears, which is being driven by climate change, scientists say.

As the world warms and Arctic sea ice thins, starving polar bears are being forced ever further south, where they meet grizzlies, whose ranges are expanding northwards. And with that growing contact between the two come increasing hybrids (杂交种).

With characteristics that could give the hybrids an advantage in warming northern habitats, some scientists guess that they could be here to stay. “Usually, hybrids aren’t better suited to their environments than their parents, but these hybrids are able to search for a broader range of food sources,” Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, told Live Science.

The rise of “pizzly” bears appears with polar bears’ decline: their numbers are estimated to decrease by more than 30% in the next 30 years. This sudden fall is linked partly to “pizzly” bears taking up polar bears’ ranges, where they outcompete them, but also to polar bears’ highly specialized diets.

“Polar bears mainly consumed soft foods even during the Medieval Warm Period, a previous period of rapid warming,” DeSantis said, referring to fat meals such as seals. “Although all of these starving polar bears are trying to find alternative food sources, like seabird eggs, it could be a tipping point for their survival.” Actually, the calories they gain from these sources do not balance out those they burn from searching for them. This could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.

“We’re having massive impacts with climate change on species,” DeSantis said. “The polar bear is telling us how bad things are. In some sense, “pizzly” bears could be a sad but necessary compromise given current warming trends.”

3 . There are around 100 tribes(部落) that live in isolation(隔绝), mostly in South America and India. The Sentinelese lived on one of the Andaman Islands in Eastern India for 60,000 years. They protect their island by fighting against people from outside. Their language is different from any other known language. Another Andaman tribe is the Jarawa. In the past, they were independent and fought against anybody trying to make contact with them. But in 1998, the Indian government built a road across their land, and since then, they’ve had more contact with the outside world.

Some Amazon tribes avoid contact because of unhappy memories. The Mashco-Piro left their vegetable gardens after rubber companies killed most of their tribe at the beginning of the 20th century. Those who survived became nomadic(游牧的) and started hunting animals in the forest.

The Awa live in the Amazon forests of Brazil. Out of 350 members, 100 have no contact with the outside world. They left their villages and adopted a nomadic lifestyle around 1850 to prevent being attacked by Europeans. In the following years, farmers in nearby communities started cutting the trees to expand their farmland. The Awa lost most of their hunting land. The few Amazon tribes that still exist are fighting to keep their traditional way of life.

Survival, an organization that fights for the rights of tribal people, says that uncontracted tribes are the most vulnerable(弱势的) humans on the planet and that’s why their environment should be closed to the rest of us. After years of pressure, the organization got Brazil’s government to clear non-natives from the Awa land. All non-Awa people are leaving, so the tribe can get their forest back.

But some think it’s impossible for tribes to stay isolated forever in a connected world. Contact will be made one day. So the question is: Whose choice should it be, ours or theirs?

1. What can we learn about the Sentinelese from the first paragraph?

A．They refused contact from the outside world.

B．They speak the same language as the Jarawa.

C．They are crazy about fighting with other tribes.

D．They have got help from the Indian government.

2. Why did the Awa choose a nomadic lifestyle?

A．To protect their hunting land.	B．To search for food sources.
C．To avoid threats from Europeans.	D．To keep their original way of life.

3. Which of the following would Survival probably agree with?

A．The tribes should be left unaffected by the outside world.

B．The tribes should fight for more living space.

C．The tribes should live in harmony with nature.

D．The tribes should follow the connected world.

4. What can be the best title for the text?

A．The Nomadic Tribes in the World.	B．Seeking Survival of Tribes.
C．The Closed Tribal Environment.	D．Protecting the Tribal Forests.

10 . “BANG!” the door caused a reverberation (回声). It was just standing there, with father standing on one side, and I on the other side.
We were both in great anger. “Never set foot in this house again!” stormed father. With tears welling up in my eyes, I rushed out of the flat and ran along the street.
The street lights were shining, causing rather sad-feeling. I wandered aimlessly.
A young father who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and carefree.
But now … I don’t know whether it is because I have grown up or because dad is getting old. We differ in our ways of thinking. He always put his opinions and codes of behavior on me. Whenever I do something wrong, he never admits it. We are just like two people coming from two different worlds. It feels like there is an iron door between us that can never be opened.
I wandered the streets, without a destination in mind. My heart was frozen on this hot summer night. As I walked on there were fewer and fewer people on th e streets, until I had only the street lights to keep me company. When I finally reached the high-rise apartment block in which I lived , I saw that the light was still on.
I thought to myself: “Is father waiting for me, or is he still angry with me?”
In fact, it was nothing. Perhaps, dad was throwing away some of his old stamps. Perhaps he thought they were useless. I never had the courage to tell him that I liked collecting stamps. I can’t stand his outrageous(蛮横的)words: “I can’t throw you away, let alone these old papers?”
All the lights were off except father’s.
Dad was always like this. Maybe he didn’t know how to express himself. After shouting at me, he never showed any mercy or any moments of regret. After an argument he has the habit of creeping up in my sleep and then tucking me underneath the covers.
This was how he always was. He has been a leader for so long that telling everyone else what to do has become his second nature.
The light was still on. “Am I wrong?” I whispered, maybe… With the key in hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door tears ran down my cheeks. I suddenly realized that the iron door that I had imagined between us did not exist(存在) at all. Love—it second to none.
