IV. Reading Comprehension Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D. Passage 1 This was the challenge Kristin Casper faced when she learned that San Francisco voters would decide on two solar power propositions (提案) last November. This probably meant to Casper, who is a Greenpeace clean-energy organizer, that they were lacking the support they’d need to pass. But she also believed that California, still in its crippling energy crisis, was ripe for solar. So Casper got help, employing five students from Green Corps, a Boston-based field school for environmental campaign organizers. By the end of their second month, Casper’s group had assured the victory of both solar propositions. Proposition B, which won 73 percent of the vote, allows the city to issue $100 million in revenue bonds (债券) to create active-solar facilities for city agencies, without imposing new taxes on its citizens. It opens the potential for San Francisco to nearly double its capacity of power generation. Proposition H allows the city to carry out future clean-energy projects without a citywide vote each time. How did they manage this? “First off,” says Casper, “the five organizers were fresh out of school and full of energy. Second, we focused on city districts we knew would turn out to vote in favor if informed.” They also targeted religious groups, which, in recent years, have increasingly shown a sense of responsibility for protecting the Earth, she says.

In the end, more than 200 volunteers got involved. They impressed more than San Francisco’s voters. Casper says officials of other cities, including Boulder, Colorado, have approached them for guidance, and they’re happy to help. “We hope to g
