In July 2024， a pod of 77 pilot whales washed up on a beach in Orkney， Scotland. It was the largest mass stranding（集體擱淺） of whales in Scotland for decades. Scientists don’t know exactly why whales beach themselves. One theory is that climate change is driving whales’ food closer to the shoreline， where they then get stuck as the tide goes out. If a single animal is found， it is usually because it is sick or has been injured.

In the Orkney stranding， 12 of the whales were still alive when they became beached. When this happens， marine organisations assess whether a whale can be safely refloated. Professionals and members of the community often come together， cover the animal in wet sheets and pour buckets of water over it， though not the blowhole， until the animal drifts back out to the ocean. Though it’s not always a happy ending.

For those that don’t survive， a post-mortem examination is often carried out. Dr Brownlow of the Scottish Marine Animal Stranding Scheme told the BBC that these can reveal a lot about the whale’s life and the reasons why it was beached. In 2024， a very rare species of whale turned up on a beach in New Zealand——a spade-toothed whale. While this is sad， the carcass（尸體） was dissected in order to help researchers acquire new information about the species. “From a scientific and conservation point of view， this is huge”， said Gabe Davies， a Department of Conservation official.

Some beached whales who don’t survive have their skeletons sent to museums， while many others are returned to the water. This ensures the marine environment benefits because whale carcasses give off many nutrients. “When they fall and die and sink to the bottom of the ocean， they form these little nutrient-rich islands that can support a huge diversity of life”， says Dr Brownlow.

The more research that can be done， the better. For now， we can only do what we can to keep our oceans clean and safe.

1. C。解析：推理判斷題。材料第一段的第三句提到“科學(xué)家們不清楚鯨魚(yú)為什么會(huì)自己去海灘”。由此可知，科學(xué)家不知道為什么鯨魚(yú)會(huì)集體擱淺。C選項(xiàng)與材料內(nèi)容相符，故選C。D選項(xiàng)為干擾項(xiàng)，那只是一個(gè)理論上的原因，未得到證實(shí)。

2.A。解析：細(xì)節(jié)理解題。材料第二段的第三句提到 “專(zhuān)業(yè)人士和社區(qū)成員經(jīng)常聚在一起，用濕床單蓋住動(dòng)物，在上面倒上一桶桶的水，但是不是在噴水孔里，直到動(dòng)物漂回大?！薄Ｓ纱丝芍?，專(zhuān)家把水澆在濕床單上，而不是噴水孔上。A選項(xiàng)與材料內(nèi)容相符，故選A。

3.D。解析：推理判斷題。材料第三段主要講述對(duì)死亡的鯨魚(yú)進(jìn)行尸體解剖的益處，材料第四段主要講述死亡的鯨魚(yú)的去處及其帶來(lái)的益處。綜合起來(lái)看，這兩段講述的是死亡的鯨魚(yú)所帶來(lái)的益處。D選項(xiàng)與材料內(nèi)容相符，故選D。

4.B。解析：推理判斷題。材料最后一段的第一句提到“研究越多越好”。這就意味著我們對(duì)海洋的研究還不夠，還須做更多的研究。B選項(xiàng)與材料內(nèi)容相符，故選B。
