Jellyfish are badly named. They are neither a fish nor made of jelly. Instead, their bodies are made up of 95% water and 5% solid matter. They have been in existence for at least half a billion years. Hence, they are older than dinosaurs. Surprisingly, they don’t have a brain, a heart, or lungs. You may wonder how they can possibly survive without these vital organs, but everything is for the best. They don’t have lungs because their skin is so thin that they can absorb oxygen through it. They don’t need a heart to pump blood because they don’t have any. And they have a nerve net—which is sensitive to touch—below their outer skin. They respond to the changes in their environment using signals from the nerve net, so they don’t need a brain to process complex thoughts.
Their variety is nearly endless. Most of them are umbrella-shaped and have tentacles. Some jellyfish have very long tentacles. However, they never get tangled up or sting themselves. That’s because the tentacles are very slippery and will only sting other animals. Most jellyfish have little or no vision, but they can detect light and ocean currents, which helps them to navigate and move. A few species can also recognize color and have a 360-degree view of their environment.
Jellyfish come in all sizes, from 0.5 millimeters to the giant Nomura’s jellyfish, which can measure up to two meters in diameter and weigh over 200 kilograms. While jellyfish are beautiful, they can also be dangerous. Some jellyfish toxins can be deadly to humans, such as those from the box jellyfish and the Australian Irukandji, but deaths are relatively rare given the number of jellyfish-sting victims every year. In any case, it’s better to stay out of the way of any jellyfish you may see. You can go swimming with dolphins, but you definitely want to think twice before swimming with jellyfish.

電價費率審議會登場，全台連續四年凍漲的電費，在全球燃料價格攀升和烏俄戰爭等因素影響下，將調整電價方案。然而剛進入炎熱的夏季，又是用電的高峰時期，要如何節能省電呢？本次就讓我們來看既環保又省荷包的小撇步，還能學會超實用英文喔！ 1. 在夜晚使用家電 Run appliances that produce heat at night — when it’s cooler. We’re talking appliances like your clothes drier, dishwasher, and oven. (Fox29) （在晚上氣溫較涼爽的時候，使用會產生熱氣的家電用品，例如烘衣機、洗碗機和烤箱。） appliance (n)「電器」是多益測驗的高頻字彙，通常出現在採購、製造、房地產等情境，描述microwave oven「微波爐」、dishwasher「洗碗機」等household appliances 或是 home appliances「家電」，經常搭配動詞install「安裝」。廚房的家電中，較為省電電器應該就是微波爐，或許減少使用瓦斯爐、烤箱對省電將有相當的助益。 According to the advertisement, the apartment is equipped with state-of-the-art appliances.（根據廣告，這間公寓備有最先進的家電。） 2. 拉起窗簾降溫 Simply closing blinds and curtains, which act as a layer of insulation can reduce heat in your home.（拉起窗簾和百葉窗做為絕緣體，可降低家中的熱氣。） insulate (v)「阻隔；隔離」通常用來描述隔絕噪音或氣溫，例如冬天時適當的insulate「隔絕」冷空氣，可以避免家中溫度太低。許多冬天穿的厚外套經常會有insulation「防風層」可以阻擋冷空氣，達到保暖的效果。 You can bring down the energy use and cost if you properly insulate your home. （房子適當的隔熱可以降低能源使用和費用。） 3. 自動調溫器 Programmable thermostats can be set, so that your air conditioner run less when you’re sleeping or when you’re at work. （設定自動調溫器，讓你在睡覺或工作時使用少一點的冷氣。） programmable「可編程的」來自program一詞，當動詞時解釋為「設定；編寫程式」，當名詞時則有許多不同的意思，例如「程式」、「節目、節目單」或「計畫、方案」，因此程式編寫可以用programming，「程式設計師」就是programmer，但是要注意的是programmer 發音時的重音是在第一音節，不要念錯。 The information regarding the newly launched recycling program is

The US Supreme Court has ruled there is no constitutional right to abortion in the US, upending the landmark Roe v Wade case from nearly 50 years ago in a rare reversal of long-settled law that will fracture reproductive rights in America. Since the US Supreme Court’s Roe v. Wade decision legalized abortion nationwide in 1973, the issue has become one of the defining fault lines in US politics, with Democratic politicians firmly supporting abortion rights and Republican lawmakers lining up in opposition. In 1973 the lines were more blurred. Republican and Democratic voters were equally likely to say abortion should be
