EN： In the UK, household energy costs are closely regulated by Ofgem (the energy regulator), which updates an 'Energy Price Cap' periodically.

中文： 在英國，家庭能源費用受到監管機構 Ofgem 的能源價格上限（Energy Price Cap）定期調控。因此，能源帳單的百分比漲幅常成為英國媒體焦點，因為暖氣與用電開銷是當地民眾生活成本中極為關鍵的負擔。

中文： 在英國房地產市場中，房屋通常習慣以「臥室數量」（如 four-bedroom house）來界定規格與規模，而非像部分亞洲地區以坪數或平方公尺為首要標準。這能讓讀者或買家一眼看出該住宅適合容納多少家庭成員。

中文： 「Will not be billed」為未來式的被動語態（will + not + be + 過去分詞）。動詞 "bill" 表示「向……收費、開帳單給……」。由於主詞（they）是被收費的對象，因此使用被動語態。
You will not be charged any extra fees for this service.
此項服務不會向您收取任何額外費用。

EN： In British English, 'fairly' is a common downtoner used to soften a statement, meaning 'moderately' or 'quite'. Being 'careful with energy' or heating is a very common topic of discussion among British households due to historically high utility tariffs and older, less energy-efficient housing stock.
中文： 在英國英語中，'fairly' 是常用的緩和副詞，表示「相當／還算」。由於英國氣候濕冷、老舊房屋隔熱普遍不佳，加上近年能源費用飆漲，「節省能源（careful with energy）」與限制暖氣使用是英國家庭非常普遍的日常話題。
EN： The combination 'only ever' is used as an emphatic adverbial phrase to mean 'never at any time other than' or 'strictly limited to'. It emphasizes that an action or state never exceeded a particular limit in the past.

He only ever drinks water with his meals.
他用餐時向來只喝水。

她第一次就通過了駕照考試，這讓所有人都很驚訝。
