第2022期:Boom in unusual jellyfish spotted in UK waters

Most of these jellyfish sightings reported to the Marine Conservation Society were in Cornwall and off the west coast of Wales. The most commonly seen was the large barrel jellyfish with a bulbous head, which can measure up to a metre wide, and eight frilled legs – it can be shocking to spot at close quarters. 人们向英国海洋环境保护协会报告的目击水母的地点大多是在康沃尔郡以及威尔士西海岸附近。最多见的是巨型桶水母，它的头部呈球茎状，头宽可达一米，还有八条褶边状的触手 —— 在近距离看到这种水母可能会令人感到很震撼。 Jellyfish populations do go through boom-and-bust cycles naturally, but climate change is also changing UK seas. A marine heatwave in June temporarily pushed up temperatures by around four degrees. The Marine Conservation Society and other experts say more research is needed to understand the precise link to climate change. 虽然水母数量本就会经历自然的周期性增长，但气候变化也在改变英国海洋和海洋生物。今年六月的海洋热浪将海水温度暂时性地提升了约四度。英国海洋环境保护协会和一些专家表示还需作进一步研究以了解水母数量增加与气候变化的确切联系。 词汇表sightings 看见，目击off the coast of 在…海岸附近bulbous 球茎状的frilled 褶边的close quarters 近距离boom-and-bust cycles “盛衰周期”，（动物数量的）周期性增长heatwave 高温热浪pushed up 提升了precise 确切的，精准的
