Everyone at the North Pole was very excited. There was going to be a show and anyone could be in it.

“I will do skating,” said Arctic Fox. “I’m good at that!”

“I’ll do tumbling (翻跟斗),”said Polar Bear. “No one tumbles quite like me!”

“Then I’ll do diving,” said Whale. “I won a prize for diving at school, you know!”

But Walrus was not good at anything.

They all practised hard for the big show, while Walrus hid behind a snowdrift and watched sadly. He wished he was good at something. Then came the big night. Everyone sat down, waiting for the show to begin. Walrus sat in the front row. excited.

Fox came onto the ice and began to skate elegantly and amazingly! Fox made it look so easy.Walrus was sure he could skate just like Fox. He leapt onto the ice and cries. “Look at me!” But Walrus bumped into Fox, and Fox went flat on her face. Flomp! Fox was very upset. “Walrus has ruined my act,” she wailed(高声数落).

Then Polar Bear rolled out across the ice like a big, white snowball. Everyone clapped wildly. Then he did jumps and spins and somersaults, and stood on his head. Walrus was sure he could tumble just like Polar Bear. Suddenly, Walrus leaped into the ice. But Walrus tripped up Polar Bear, who came down with WALLOP! Polar Bear was very angry. “Walrus has ruined my act!” he waited.

Whale was the last. He leaped high out of the water. Then he fell back with an enormous splash! Walrus wished he could dive like that. He leaped into the water, crying “Look at me!” But just at that moment, Whale was spouting a big jet of water. Whoosh! Whale spouted Walrus high into the air! Everyone was watching Walrus. They clapped and cheered at Walrus landed back in the sea with a splash!

Whale roared angrily. “You have ruined my act. Get out of my sight!” Walrus fled and hid behind a snowdrift, feeling sad and a very sorry.

3 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.

Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.

While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.

In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.

Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.

These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.

2. What is the advantage of Raman microscopy?

B．To be aware of the dangerous particles in daily life.

C．To further measure the types of particles in tap water.

D．To detect the smaller plastic particles in industrial areas.

4. What is Qian’s attitude towards his research?

An Interview about Plastic Pollution

8 . Macquarie Island is a tiny island that’s part of Australia. It’s about halfway between New Zealand and Antarctica. The island’s been made a world heritage area because it’s so untouched, but this unique environment is under threat from some unwanted visitors.

It all started when seal hunters came to the island in the early 1800s. They brought rabbits with them as a source of food for the journey, and also on board the ships were rats and mice, which made their way onto the island too. They’re being blamed for destroying the homes of marine birds, causing soil loss and ripping up plant cover, as these before-and-after photos show.

So what’s being done about the problem? It starts with a team of helicopters that fly across the island carrying these giant containers. Inside them are poisoned pellets (有毒饲料) which are dropped and spread across the island. For any rabbits that survived the baiting (诱饵) , there’s a plan B. This special team of dogs is being put through a final training. It’ll be their job to track down any remaining rabbits. They have to also learn to behave around the island’s native wildlife. The dogs could be here for years or until the task is complete. The dogs don’t actually kill the rabbits. They find them, then the hunters decide to either catch the rabbits or shoot them.

But the program has received a bit of criticism. Some people argue 25 million dollars is a lot of money to be spending on wiping out rabbits and rodents (啮齿目动物), and in the process, some native birds will be killed because of the baiting.

The reality is the problem isn’t going to be solved overnight. The people running the program say that even if one pair of rabbits is left alive, the whole task will be seen as a failure, which means these guys could be here for a long time, trying to ensure that this precious island remains protected from pests.

1. Who are these unwanted visitors?

A．Seal hunters.

B．Marine wildlife.

C．Native birds.

D．Foreign species.

2. What do the underlined words “ripping up” mean in paragraph 2?

A．Advancing.

B．Destroying.

C．Dividing

D．Balancing

3. What is being done to solve the problem of unwanted visitors on Macquarie Island?

A．Poisoned pellets are being dropped on the island from helicopters.

B．A team of hunters is being trained to catch or shoot rabbits.

C．Native birds are being protected from the unwanted visitors.

D．A special team of dogs is being sent to kill the rabbits.

4. What is the goal of the program?

A．To spend as little money as possible.

B．To protect native birds from the unwanted visitors.

C．To ensure that no pair of rabbits survive on the island.

D．To train dogs to track down the rabbits on the island.

9 . 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。

The Voyager Program was conceived as a grand tour of the solar system. It was actually     1     engineer in the Jet Propulsion Laboratory that realized in the late ‘70s there was going to be a     2     (gold) opportunity. And that was     3     the planets were all going to more or less line up on one side of the sun. And that’s really important when you’re trying to explore one planet after another, because of course all the planets in the solar system are orbiting     4     (independent). Sometimes we’re on, say, the same side of the sun as Jupiter is     5     sometimes Jupiter is way on the other side of the sun from us, you know, many, many, many billions of miles away. So, there was this time coming in the late ’70s       6     you could launch a spacecraft and it could actually go to Jupiter, but then onto Saturn, because they were both on the same side of the sun, and you could even possibly get Uranus and Neptune and maybe even Pluto.

The fly-by trips     7     (involve) the four planets became known as the Voyager “Grand Tour.” And this was the Voyager program: Voyager I and Voyager II. NASA officials have said that when first     8     (launch), the Voyager mission was expected to last five years. Both Voyagers are the only spacecraft so far     9     (explore) interstellar (星际的) space. And over the last couple of years, we     10     (follow) them through this transition truly out of the range of our solar system.
