单选题{{B}}Passage 15{{/B}} Thousands of years ago, in the middle of an ocean, miles from the nearest island, an undersea volcano broke out. The hot liquid piled higher and higher and spread wider and wider. In this way, an island rose up in the sea. {{U}}(15) As time went on, hot sun and cool rains made the rock split and break into pieces, sea waves dashed against the rock.{{/U}} In this way, soil and sand came into being. Nothing lived on the {{U}}naked{{/U}} soil. And then the wind and birds brought plant seeds, spiders and other little creatures there. Only plants could grow first. Only in sunlight could they produce food from the minerals of the soil, water and air. While many animals landed on the island, they could find no food. A spider spun its web in vain, because there were no insects for its web to catch. Insects couldn't stay until there were plants for them to eat. So plants had to be the pioneer life on this new island.

单选题In 1366, sailors on a German ship called Paula threw a bottle with a message into waters hundreds of miles off the western coast of Australia. One hundred and thirty-one years later, (76) the bottle was found on an Australia island. It"s believed to be the oldest-known message in a bottle, in terms of the amount of time that has passed between when it was written and when it was found. Before this discovery, Guinness (吉尼斯)World Records said that the oldest was 108 years old, found in Germany in 2015. Australian and German researchers worked together to check whether the note is real or not. Tonya Illman was walking on the beach in January when she spotted the old bottle. "I picked it up thinking it might look nice on display in my home," Illman says, according to an account on her husband"s website. (77) The bottle was partially filled with wet sand . Shortly after, Illman"s son"s girlfriend poured out the contents and found a tightly rolled note covered in a piece of string. Too damp to open initially, according to the account, the group waited for it to dry and were amazed to see that it was carefully handwritten in German. "The first thing that caught my eye was the year 1366," said Illman"s husband Kym. "It seemed totally unlikely to us that the note and bottle could have lasted that long." The pair reached out to the Western Australia Museum, which set out to study the document. "Extraordinary finds need extraordinary evidence to support them, so we contacted colleagues in Germany for help to find more information," Ross Anderson, who is in charge of works of art in the museum, said in a statement. But this message is no SOS or love letter.
