单选题Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as long as 3, 000 mil lion years. When we think of the first life on land, we probably think of strange animals coming out of the oceans, but, in fact, no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with food necessary to live, since they are the only form of life that is able to get and store energy. The first plants to exist out of the water were probably certain kinds of algae(海藻) which were followed by other plants that grew close to the ground near water and needed water in which to repro duce. Once the move to land had been made, however, evolution (进化) took place quickly. By the end of 100 million years, plants had developed their roots, and some developed tall tree like forms, since height was very important in competing for sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.

单选题For 20 months the wrecked Costa Concordia has been lying on its side near the coast of Giglio, a small Italian island. But on Tuesday, as part of the largest salvage (打捞) operation ever conducted, the large ship was finally moved to the upright position. The next step is for the vessel to be removed from the area entirely. The Costa Concordia is twice the weight of the Titanic. The ship itself didn"t budge (稍微移动) for the first three hours of the operation, Sergio Girotto told reporters. He and other engineers worked for 19 hours before Concordia was declared completely upright. The Costa Concordia capsized on January 13, 2012, after its captain, Francesco Schettino, brought the ship too close to the shore. The ship hit coastal rocks, which caused serious damage and allowed water to pour in. Most of the 4,200 people on board made it to land safely, but more than 30 people were killed in the disaster. Two people remain missing. The Concordia"s captain is currently on trial for causing a shipwreck and abandoning his ship. The operation to right the ship is called parbuckling. While parbuckling is a standard operation to right capsized ships, it has never before been used on such a large ship. Workers had been waiting for favorable weather conditions to undertake the operation. On Monday, authorities gave the final go-ahead. The process was expected to take no more than 12 hours. But problems with the large system of steel chains caused delays. Engineers worked through the night using cables and metal water tanks to roll the ship onto special platforms. The Concordia is expected to be pulled away from Giglio in the spring of 2014 and turned into scrap metal (废金属). The ship"s owner, Costa Cruises, will pay for the recovery, which has already cost more than ＄800 million.
