A pond in Hawaii has turned so pink that it could be from the Barbie movie—but it's no cause for a dance party. Drought may be reason for the strange colour, scientists say, and they're warning against entering the water or drinking it.
Workers at the Kealia Pond National Wildlife Refuge (遇难所) on the island of Maui have been watching the situation of the pink water since October 30, 2023, after getting a phone call from somebody who was walking on the beach.
"I just got a report from somebody who was walking on the beach, and they called me up like 'There's something weird going on over here'," said Bret Wolfe, the refuge manager.
Wolfe was concerned the bright pink could be a sign of an event called an algae bloom (绿藻泛地), but lab tests found such algae was not causing the colour. Instead, an organism (微生物) called halobacteria might be the cause.
Halobacteria are a type of organism that lives in bodies of water with high levels of salt. The salinity (盐度) inside the Kealia Pond outlet area is now greater than 70 parts per thousand, which is twice the salinity of seawater. Wolfe said they will need to study the DNA to confirm the organism.
Maui's drought is likely leading to the situation. Normally Waikapu Stream feeds into Kealia Pond and raises water levels there, but Wolfe said that hasn't happened in a long time.
When it rains, the stream will flow into Kealia's main pond and then into the outlet area that's now pink. This will reduce the salinity and potentially change the water's colour.
The refuge has seen an increase in visitors after photos of the pink pond were posted on social media. Wolfe said he would love to have visitors come to learn about local aims to protect nature.
But officials have announced a special warning for people not to enter the water or eat any fish caught there.

答案： 【语篇解读】本文是一篇新闻报道。文章介绍了夏威夷的一个池塘变成了粉红色。科学家说，干旱可能是产生这种奇怪颜色的原因，但事实的真相究竟是什么呢？
28.A 词义猜测题。根据第一段中的A pond in Hawaii has turned so pink that it could be from the Barbie movie...和画线词上文I just got a report from somebody who was walking on the beach，and they called me up like...可知，池塘的水变成粉红色这是非正常现象，这个人打电话就是要汇报这件奇怪的事情。由此推测，画线词意思为非同寻常的。故选A。
29.C 细节理解题。根据第五段中的Halobacteria are a type of organism that lives in bodies of water with high levels of salt. The salinity(盐度)inside the Kealia Pond outlet area is now greater than 70 parts per thousand，which is twice the salinity of seawater.可知，人们是根据这个池塘的异常的含盐度来推测是这种细菌导致水的颜色变化。故选C。
30.B 推理判断题。根据第五段最后一句Wolfe said they will need to study the DNA to confirm the organism.可知，该机构会继续研究这个问题，以确定其真正原因。故选B。
31.D 标题归纳题。根据第一段并综合全文可知，本文主要介绍了夏威夷一个池塘的水突然变成了粉色，这是很离奇的现象，及人们对这一怪异现象的研究。故选D。
