三．阅读理解（每小题2.5分，共10分）
Heidi Tait, co-founder of Tangaroa Blue Foundation, an organization committed to beach cleaning, was puzzled when she and her teammates started finding strange tire-shaped capsules washed ashore along the Cape York coast, near Australia's northeastern tip. But Tait eventually connected with Satlink—a Spanish satellite communications company. Satlink's GPS-enabled buoys（浮标）, the ones the beach cleaners kept finding, help commercial fishers track their nets, lines etc. Tait had a brainwave that would see the buoys not just recycled but reused.
For more than a decade, boat crews working farther west,in Australia's Gulf of Carpentaria, had been telling Tait about how abandoned fishing nets were circling the gulf, hurting sea creatures. These so-called ghost（幽灵）nets had either broken free from commercial fishing boats and gotten lost, or were cut loose by fishers after getting caught on rocks. Weighing a few tonnes each, the nets that boat crews had chanced upon in the gulf were often too big for them to pull out of the water. They'd typically report the finds to the authorities, but by the time anyone with an appropriately equipped boat could head out to get one, the mass of messy rope had often gone from sight.
However,once one of the GPS-enabled buoys is attached,it sends its location every few hours to a website, which lets Tangaroa Blue Foundation monitor the nets' movements and warns the organization of danger. So far, the reused GPS trackers have helped Tangaroa Blue Foundation recover three ghost nets from Australian waters.
Tangaroa Blue Foundation's idea to track ghost nets isn't entirely new; researchers with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia's national science agency, suggested it a decade ago. Taking the idea on board, the authorities tried using battery-powered trackers to monitor a few ghost nets. Tangaroa Blue Foundation's approach differs in that its recycled buoys are solar-powered and require less upkeep.
1. What were the tire-shaped capsules originally used for
A. Removing beach waste. B. Recycling vehicle tires.
C. Locating fishing equipment. D. Strengthening satellite signals.
2. What does the author intend to do in paragraph 2
A. Illustrate a future possibility. B. Describe a technical process.
C.Present a practical solution. D. Frame a problem context.
3. How do Tangaroa Blue Foundation's buoys outperform earlier trackers
A. They need less maintenance. B. They monitor broader regions.
C. They receive government funding. D. They provide precise tracking data.
4. What is the best title for the text
A. Turning Waste into Treasure:A Fix to Ghost Nets
B. Fighting Threats:The Hidden Harm of Ghost Nets
C. Financing Change:Innovative Ocean Cleanup Plans
D. Protecting Seas from Waste:An Activist of Conservation

We need to recognize that it's 13 not to be great at something. Perfection is often 14, and more often than not, we are our toughest critics. The challenge, then, is finding the balance between enjoyment and 15. Embrace imperfection, and enjoy the process, even if you're not "great" at it.
