题目

A wave of startups say seaweed is a solution to climate change — able to absorb atmospheric carbon, provide raw materials for bio-fuels, and feed the world no fertilizers (化肥), fresh water, or even land required. Running Tide, a Maine-based company, is working on a system that will eventually sink the buoys(浮标), attached with long locks of seaweed, to the deep ocean floor, where the carbon they contain will remain stored for 800 years or more.Running Tide was founded by Marty Odlin, an engineer and fourth-generation commercial fisherman. The Gulf of Maine is warming faster than nearly every other oceanic region, and Odlin has seen the changes firsthand. About 15 years ago, Odlin heard a talk from Klaus Lackner — the physicist who popularized the idea of removing carbon from the atmosphere. It clicked. "It was like, oh, this is right because there's no way we're going to get off fossil fuels in the next 50 years," he recalls thinking. "We're going to have to pull it down."Using seaweed to draw down carbon would be an elegant solution — if it works. Seaweed forests collectively cover an estimated two million square kilometers and absorb as much carbon as the Amazon rainforest. But much of that storage is short-lived. When the seaweed is harvested, eaten by animals, or washes ashore, its stored carbon is released back into the atmosphere. Running Tide's model, in theory at least, would take that stored carbon and sink it to the ocean floor where it would remain for centuries, breaking down slowly.Some scientists are careful about rushing ahead before fundamental scientific, environmental, and regulatory questions are answered. "Climate change is worsening, and people are panicking," says Kristen Davis, a professor of University of California Irvine, "but the science is not there yet to actually confirm that it's a good idea." （1） What can we learn about Running Tide's system? A . It stores seaweed as food sources. B . It converts seaweed into fertilizers. C . It uses seaweed to absorb carbon. D . It produces buoys for planting seaweed. （2） What inspired Marty Odlin to start Running Tide? A . The overuse of fossil fuels. B . His observation of the rapid climate change. C . His responsibility as a commercial fisherman. D . A talk by Klaus Lackner about removing carbon. （3） What does paragraph 3 mainly talk about? A . The coverage of seaweed forests. B . The carbon absorbing ability of seaweed. C . The advantages of seaweed for carbon storage. D . A possible solution to long-term carbon storage by seaweed. （4） Why does the author quote Kristen Davis? A . To prove Odlin's opinion. B . To present the issue objectively. C . To advocate scientists' cooperation. D . To emphasis the climate crisis. 答案： C D D B
