【2016模拟题】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
Scientists recently found three animal species living two miles below the surface of the Mediterranean Sea, where the super-salty waters don’t have oxygen(氧). They’re multicellular(多细胞的), which means their bodies have many cells. They each are as small as a large grain of sand. But they are animals.
The most exciting thing about these creatures, say the scientists, is that they obviously don’t need oxygen to live. What biologists know about life so far is that only single-celled living things can live in places that have no oxygen, and that multicellular organisms(有机物) can visit these places, but not live there. These newly found creatures could change that idea.
Finding animals down there was so surprising that the scientists couldn’t believe it. At first, “we thought they were dead bodies,” Roberto Danovaro, a scientist at the Polytechnic University of Marche in Ancona, Italy, told Science News. To find out whether the animals could actually live there Danovaro and his colleagues brought up more samples(样本) from the ocean floor. Studying the animals in the new samples showed that they appeared to be alive.
The researchers did more tests, and found that some of the animals had eggs—which suggests they were reproducing(繁殖). Also in the samples were old skins, suggesting that the animals had lived there long enough to grow. Finally, pictures taken showed that the insides of the animals appear to be adapted to live in an environment that has no oxygen.
