1 . Buck’s first day on the beach was a nightmare. Every hour was filled with shock or surprise. He had been suddenly removed from civilization and thrown into the heart of a primitive world. Here there was neither peace nor rest, nor a moment’s safety. It was essential to be constantly alert, for these dogs and men were not town dogs and men. They were savages, all of them, who knew no law but the law of Club and Tooth.

Buck had never seen dogs fight like these, and his first experience taught him an unforgettable lesson. He was fortunate that it was Curly who was the victim, not himself. Curly, in her friendly way, tried to make friends with a husky dog. The dog was the size of a full-grown wolf, but not half as large as Curly was. There was no warning: only a fast jump, a metallic cut of teeth, and a jump back. Curly’s face was ripped open from eye to mouth.

It was wolf fighting, to strike and jump away, but there was more to it than this. Thirty or forty huskies ran to watch. They surrounded the fighters in a silent, watching circle, all licking their lips. Curly rushed at the husky, who struck again and jumped away. He met her next rush with his chest in a strange way that knocked her over. She never got up again. This was what the watching huskies had waited for. They closed in on her, snarling and yelping. Curly was buried, screaming in pain, under the dogs’ bodies.

4 . A researcher with the Australian Antarctic Division left a camera near a large group of emperor penguins. Then two of the birds walked over to check the camera out. The camera was rolling when the penguins started to look into its lens (镜头), resulting in a very cute penguin "selfie (自拍)". That's according to Amy B. Wang of the Washington Post.

Explorer Eddie Gault placed the camera near the Auster Rookery during his visit to Australia's Mawson research station. The Australian Antarctic Division posted a short video from the camera—happy penguins on its social media pages. They wrote that it offered a "bird's eye view of life in Antarctica"!

At the start of the video, we can only see the feet of a penguin. It appears to kick the camera over so its lens faces the sky. As the penguin looks into the camera, another comes into view. The buddies come towards the lens and cock their heads. Then they straighten up and shake their heads. It is as though they have decided that this strange object is not worth their time.

Penguins are "naturally curious" animals, the Australian Antarctic Division writes on its Facebook page.

Other animals have also been known to get involved in the art of the selfie. An eagle in Western Australia once picked up a camera that was supposed to be recording fresh-water crocodiles. It filmed itself flying and touching at the lens.

Then there is a monkey that accidentally started a year-long lawsuit (诉讼) when it took a funny photo of itself with a camera owned by David Slater. He is a British wildlife photographer. Slater published the image of the monkey in a book, which caused People for the Ethical Treatment of Animals to take him to court for breaking the copyright of the so-called "selfie monkey".

Slater said himself that the monkey had pressed the shutter on his camera, which proved to be the heart of the case against him.

As for the Antarctic penguins, the camera was already rolling when they decided to "strike a pose", so the Australian Antarctic Division should be able to avoid a possible lawsuit. But if you happen to be in the Antarctic and see two penguins taking top-down Instagram shots of their latest meal, you know who is responsible.

1. The underlined word "rolling" in Paragraph 1 probably means _____.

A．flashing

B．moving

C．recording

D．turning

2. According to Paragraph 3, which picture correctly shows the penguins' behavior?

A．	B．
C．	D．

3. David Slater faced a lawsuit because _____.

A．he used the monkey's selfie in a book

B．the monkey pressed the button on his camera

C．the monkey took a photo of him with his camera

D．he published a photo of the monkey on the Internet

4. Where can you probably read the passage?

A．In a law book.	B．In a research report.
C．In a photographer's diary.	D．In a wildlife magazine.

7 . 阅读下面短文，根据题目要求用英文回答问题。请在答题卡指定区域作答。

Balancing Trees and CO₂

Tree planting used to be regarded as an effective means of reducing climate change. Perhaps it’s time for us to rethink this practice. Trees pull CO₂ from the air. This effectively removes CO₂ from the atmosphere. But trees only hold onto CO₂ as long as they’re alive. Once they die, trees decay (腐烂) and release that CO₂ back into the atmosphere.

Recent studies have found that trees around the world are growing faster than ever. The rise of CO₂, mainly due to burning fossil fuels, is probably driving that rapid growth, said Roel Brienen, a forest ecologist at the University of Leeds, UK. High levels of CO₂ are increasing temperatures, which in turn speeds tree growth in those areas, he added.

The faster trees grow, the faster they store carbon. It seems like good news. However, it is known that fast-growing tree species, in general, live shorter lives than their slow-growing relatives.

In order to see whether the growth-lifespan trade-off (生长与寿命之间的权衡) is a universal phenomenon, Brienen and his colleagues analyzed over 210,000 individual tree ring records of 110 tree species from more than 79,000 sites worldwide. They found that, in almost all habitats and all sites, faster-growing tree species died younger than slow-growing species, and even within a species, the trade-off between growth and life span held strong.

The team also created a computer program that modeled a forest and tweaked (微量调整) the growth of the trees in this model. Early on, it showed that “the forest could hold more carbon as the trees grew faster”, Brienen reported. But after 20 years, these trees started dying and losing this extra carbon again. “We must understand that the only solution to bringing down CO₂ levels is to stop emitting (排放) it into the atmosphere,” said Brienen.
