2 . Most plants you see out in nature are leafy and green, at least for some part of their lives. That’s because they use green pigments, which are called chlorophyll (叶绿素), to harvest energy from sunlight. But the plant Hydnora Africana, doesn’t have leaves or chlorophyll at all.

So, how can it survive? Well, it’s a parasite (寄生), and H Africana attaches itself to other plants’ roots, and begins getting sugars, minerals, and water from its host.

At the same time, the parasite grows a root system, living completely underground, until it’s ready to reproduce. At which point, it grows one of the strangest looking flowers in the world. When the flower’s mature, it breaks the soil from beneath and reaches out in order to be pollinated (授粉).

But just as this plant doesn’t look like the normal flower, it doesn’t smell like one either. It gives out a smell like a rotting (腐烂) animal . The smell attracts insects and flies looking for a delicious meal. But when they get inside the flower and find no tasty treat, they can’t get back out again.

There’s a sort of room inside the flower, and the top of the room closes behind the insects. The walls of the flower are also slippery, making escape even more difficult.

Over the course of about a day, the flower’s male organs mature, and the insects get coated in pollen. And at the end of this transformation, the inside of the plant gets less slippery, and the chamber opens, allowing the insects and flies to escape.

At that point, attracted by a new rotting smell, they might just find another H Africana flower and pollinate it as they fall inside.

1. Why is chlorophyll so important to plants?

A．Chlorophyll gives plants green color.

B．Chlorophyll helps leaves to grow.

C．Chlorophyll can harvest energy from sunlight.

D．Plants cannot survive without Chlorophyll .

2. About H Africana, which description is right?

A．It’s a parasite without roots.

B．It gets food through other plants’ root.

C．It never grows out of the ground.

D．Its flowers smell sweet.

3. The insects attracted to pollinate will _____.

A．find tasty treat inside the flower.

B．never get out of the flower again.

C．get little chance to pollinate successfully.

D．escape after being trapped about a day.

4. The passage mainly interprets______.

A．What is a parasite.

B．How a parasite to survive.

C．How H Africana reproduce.

D．Why bad smell is so useful.

Scientists are racing to study the volcano in Tonga that    1     (erupt) just before sundown on January 15,2022.

“Everything so far about this eruption is really strange,” said Janine Krippner,    2     scientist working on Smithsonian’s Global Volcanism Program. “The sound of the explosion, the tsunami(海啸) waves that followed eruption and the huge energy of this explosion,    3    equaled to five to six million tons of TNT, were unlike any seen in recent     4    (year).”

The tsunami waves that followed the eruption    5     (be)even stranger. Tsunami waves usually start from the center of the eruption. Yet this time, waves appeared in other places far earlier than would be expected of a classic tsunami.     6    addition, as tsunami waves travel further, they usually become    7    (weak).While the waves that hit the islands in Tonga were damaging, they weren’t high enough to account for the surprisingly larger waves across the ocean.

Monitoring underwater volcanoes is a complex task. GPS — which is frequently used     8    (track) changes in the surface-doesn’t work on the seafloor. The situation in Tonga shows how well the Tonga Geological Services(TGS)has been applied to    9    (deal) with the latest eruption. “They don’t have a huge amount of money. They don’t have a number of staff, either.” Janine Krippner added. “But     10    (actual) they have done a really nice job to reduce the possible.

7 . 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。

Police Outpost Lake is as far south as you can go in Canada. In fact, next to the lake are the protected wetlands, where songbirds, ducks, and Canada geese glided by on the breeze, touching down briefly on the water’s surface before flapping (振翅) their way back up into the sky.

Standing at the lake’s edge, my cousin, Allan, and I cast our fishing lines separately onto the smooth-as-glass water. Down the shoreline was Allan’s father, my uncle Rick. He liked to fish alone, away from distractions, noise, and other people.

Allan shouted, “Dad, where should I stand?”

Uncle Rick pressed his finger to his lips, pointed to a shady spot by a large rock where he had cast his line and shook his head gently.

“He wants us to be quiet or else we won’t catch any fish.” I whispered.

“Why do I have to be so quiet?” asked Allan. “All those birds are making more noise than I ever could!”

I ignored him, pulling back on my rod gently and squinting into the glare of the sun. Out of the corner of my eye, I caught a glimpse of a few great northern loons (潜鸟) gathering together not far from the shoreline. What were they doing there? Loons usually travel alone, but here were five of them in a cluster. Maybe it was a family? Just then one loon, making a loud painful cry, swam away from the group, toward me.

“Allan! Come here. Now!”

Allan laid his fishing rod down on the dirty sand, darting toward me.

“Come here. Take a look at that loon. It’s swimming toward us, not far away from us. It’s trying to get our attention.”

The loon finally stopped in the shallow water near shore, not ten feet away from us. It was so close that we could see its round red eyes. Strangely, the bird’s wings were held tight against its body.

Wading into the water and getting closer to the loon, we both saw a fishing line wrapped tightly around its neck and a shiny red hook (鱼钩) in its body. Left like this, the loon couldn’t fly or fish or survive. It was asking us to help!

“Go fetch the scissors from the fishing box,” I urged Allan.

8 . The dodo, a Mauritian bird last seen in the 17th century, will be brought back to a semblance (外观) of life if attempts by a gene-editing company are successful. Gene-editing techniques now exist that allow scientists to extract the dodo genome (基因组) that they believe they can then effectively recreate within the body of a living relative.

The scientists in question said their work, beyond providing an insight into the extinct dodo’s existence, could help inform the conservation of rare species that are not yet extinct. However, there is a fierce debate among biologists over whether this sort of research should be pursued.

Beth Shapiro, the lead paleo-geneticist (古遗传学家) at Colossal, told the Guardian she tried to persuade a museum to let her extract DNA from a preserved dodo exhibited there. She said there were hundreds of dodos in collections around the world, so it had been possible to sequence the dead bird’s genome. But she warned that the revived dodo could never replace what has been made extinct. “It would be crazy to think the solution to the world’s biodiversity crisis was to bring back a proxy.” she said.

Ben Lamm, the chief executive of the company, said they were raising a further 150 million dollars to pursue the research on the dodo. He pointed out that it could assist conservation efforts for many other threatened species around the world, as it would develop techniques that could allow scientists to detect and preserve key features in those existing species that could help them adapt in a changing climate.

Prof. Ewan Birney from European Molecular Biology Laboratory, who was not involved with Colossal’s work, said it would be “very, very challenging” to recreate the dodo genome. He added, “I’ve no idea whether the project will work as they claim, but the question is not just ‘can you do this’, but ‘should you do it?’ … I’m not sure what purpose it serves, and whether this is really the best distribution of resources. We should be saving the species that we have before they go extinct.”

1. What can we learn about dodo from the text?

A．It is a bird that is only unique to Mauritius.

B．The research on it has raised conflicting opinions.

C．It has been successfully brought back to life.

D．It could be recreated within the remains of a relative.

2. What does the underlined word “proxy” mean in paragraph 3?

A．fake

B．creature

C．model

D．replacement

3. What’s Prof Ewan Birney’s attitude towards Colossal’s work?

A．Critical
