Recently, a research team in northern Europe announced a bold plan: using gene-editing technology to bring back a cold-resistant variety of wild grass that disappeared from the region fifty years ago. The grass, they argue, could hold the soil together on windy hillsides, slow down erosion, and even capture carbon dioxide from the atmosphere. Yet the proposal has drawn sharp criticism. Ecologists warn that a resurrected plant is not the same as the one that vanished. Its genes have been altered to survive today's climate, and no one can predict how it will interact with insects, fungi, and other plants that have changed in the meantime. Once released, the grass could spread beyond the target area and push out native species that are already struggling. "We are not simply replanting a meadow," says Dr. Elena Marsh. "We are introducing a living experiment into an ecosystem we do not fully understand." Supporters reply that the risks must be weighed against the cost of doing nothing. Eroded hillsides lose thousands of tons of soil every year, and traditional replanting with ordinary grasses has produced poor results. They also point out that the team has proposed a slow, step-by-step release, with each stage closely monitored and a plan ready to halt the project if problems appear. The regional government has not yet made a decision. Whatever it decides, the debate has forced a wider question into the open: how far should we go in engineering nature to repair the damage we have caused? What is the author's attitude towards the gene-edited grass project?

阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 When I was twelve, my grandfather took me to the salt marsh behind our village every summer evening. He never spoke much while we walked; he simply pointed at the herons that stood motionless in the shallow water and waited for me to notice how still they were. "Patience," he would say, "is what the marsh teaches best." At the time I thought the place was dull, dusty and full of mosquitoes. Thirty years later I work in a city where everything moves at once. Last month, however, a new wetland reserve opened on the edge of town, and on its first morning I found myself standing at the reed-lined boardwalk, watching a grey heron lift slowly from the water. The bird did not hurry. For a moment the city behind me seemed to fall silent, and I heard again my grandfather's low voice. I have since learned that the reserve was created after local volunteers spent four years persuading the government to stop a housing project there. Their reports showed that the marsh filters rainwater, shelters migrating birds and stores carbon that would otherwise enter the atmosphere. What struck me most, though, was not the data but the volunteers' patience: they attended meeting after meeting, prepared document after document, and never once raised their voices. My grandfather died before the reserve existed, yet standing there I felt he had somehow been part of its story. The heron, the waiting, the refusal to rush — these were his lessons, now written into the landscape itself. What can we infer about the author's attitude toward the wetland reserve?

阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 When the other children laughed at her torn shoes, Maya did not cry. She lowered her eyes, pressed her lips together, and then bent down to tie her shoelaces again, as if nothing had happened. Her teacher, Ms. Lin, noticed every detail. "I once watched her pick up a plastic bottle from the playground and drop it into the recycling bin," Ms. Lin said. "She never told anyone. That is who she is." Years later, Maya returned to the school as a volunteer, teaching children how to sort waste and protect the river behind the campus. "People ask me why I care so much about rubbish," she told the students, smiling. "I tell them that the earth cannot speak for itself, so we have to speak for it." What can we infer about Maya's character from the description of her actions?

Paragraph 2: When the rescue team finally arrived, they found the baby panda safe in Lin Tao's arms. Lin Tao, a 19-year-old volunteer, was patrolling a mountain nature reserve in Sichuan after a heavy storm. Fallen trees blocked the narrow path, and the river below roared louder than usual. He knew the storm had driven many animals out of their shelters. Suddenly he noticed a series of muddy paw prints leading toward a steep slope. Carefully following them, he discovered a small cave behind a rock. Inside, a baby panda, no bigger than a cat, was shivering and crying weakly. Its mother was nowhere to be seen. Lin Tao reached for his radio, but there was no signal. He remembered the team rule: never leave an injured animal alone, but never put yourself in danger either. The slope was slippery, and darkness was falling fast.
