(D)
The blue whale (鲸) is the largest animal alive today. And one of these whales made a long journey through the South Pacific. The whale named Isabellla was first recorded near the Galapagos Islands, west of Costa Rica. Years later, people saw Isabellla off the coast (海岸) of Chile in South America. The two places are about 5,200 kilometres away.
Blue whales are found in all the world’s oceans (海洋) but live in deep waters. So there are few places where they can be found easily. What’s more, they were almost driven (驱逐) by whaling (捕鲸业) a century ago. Their number is increasing (增加). But because there are so few of the animals, they are still thought endangered (濒危的).
One blue whale may look like any other to most of us. But each animal has special spots (斑点). “We use those spots as the fingerprints (指纹) of blue whales,” Torres Florez says. To make the comparison (对比) job easier, scientists mainly watch the area around a whale’s dorsal fin (鳍), which is on its back. “Comparing those spots, we are able to tell if a whale is the same whale we saw in different places or if the same whale is seen during different years in the same place,” he says.

(1)[1]实验中调节烛焰中心,透镜中心,光屏中心大致在同一高度。目的是使像成在光屏的中央。
[2]实验中平行于凸透镜主光轴的光经过透镜后在主光轴上的交点即为凸透镜的焦点。焦点到透镜光心的距离就是焦距,图甲中光屏到透镜中心的距离是焦距,大小为
(2)[1][2]根据凸透镜的成像规律可知,当时,成倒立、放大的实像,此时,,由乙图可知此时物距小于像距,成像原理与此相同;生活中投影仪是用这一原理工作的。
(3)根据凸透镜成实像时,物远像近像变小的规律,若保持图乙中凸透镜的位置不变,向左移动蜡烛到某一位置,物距变大,成清晰的像的像距变小,应向左适当移动光屏,才能再次得到清晰的像。
(4)若保持图乙中凸透镜位置不变,向右移动蜡烛至45cm刻度线处,物距小于焦距,成正立、放大的虚像,且像、物同侧。这时要观察到像人眼应在图中B处且朝着相应方向看。
(5)若此时用硬纸片挡住凸透镜下半部分,物体表面射向透镜的光被纸片挡住一部分,折射到光屏上会聚成像的光变少,成像变暗,但像的大小、形状不变。
故选D。
