Electricity 指一種由電荷流動產生的能量形式，是現代科技與生活的基礎。
物理現象
EN: A form of energy resulting from the existence of charged particles, such as electrons or protons.
翻譯: 一種由帶電粒子（如電子或質子）存在而產生的能量形式。
電力供應
EN: The supply of electric current to power homes, industries, and devices.
翻譯: 為家庭、工業和設備供電的電流供應。
科學領域
EN: The branch of physics that deals with electric phenomena.

判斷 electricity 在句中是主詞或受詞，有助於釐清句子是在描述電的特性，還是在說明人對電的操控。
electricity vs energy
「electricity」專指由電荷流動產生的「電」，是一種具體的能源形式；而「energy」是泛指所有「能量」或「能源」的總稱，概念更廣泛。
electricity vs current
「electricity」是「電」的總稱，指與電荷相關的物理現象；「current」特指電荷的流動，即「電流」。
electricity vs power
「electricity」是「電」這種具體的能源；「power」在工程或物理上常指「功率」（做功的速率），但在日常語境中也常作為「電力」或「能源」的同義詞使用。
在對話中，當引述或轉述他人關於電力或電費的評論時，常會用「electricity」來指代這個概念。 EN: She was complaining, "The electricity bill this month is insane." 翻譯: 她當時在抱怨：「這個月的電費高得離譜。」
EN:He just said, "Make sure you turn off the electricity before you touch those wires."
翻譯:他剛才說：「碰那些電線之前，一定要先把電關掉。」
在口語中，會透過重音或語調來強調「electricity」，以表達驚訝、擔憂或重要性。 EN: We used HOW MUCH electricity last month? 翻譯: 我們上個月用了『多少』電啊？
EN:This whole village runs on solar power; they don't even have electricity.
翻譯:這整個村子都靠太陽能運作；他們甚至連『電』都沒有。
在思考或組織語句時，有時會用「the electricity...」或「electricity, you know...」作為短暫的停頓填充詞。 EN: The problem with the project is... the electricity... the infrastructure just isn't there yet. 翻譯: 這個專案的問題是…那個電力…基礎設施根本還沒到位。
EN:It's all about managing, electricity, you know, consumption and costs.
翻譯:這完全是關於管理，電力，你知道的，消耗和成本。
正式寫作注意：在正式或學術寫作中，應避免將「electricity」用作停頓填充詞，並確保其用法精確且符合上下文。口語中的強調語調也無法在書面文字中直接呈現，需改用其他修辭方式來表達重點。

切斷電力
×I need to buy an electricity.
✓I need to buy electricity.
"electricity" 是不可數名詞，前面不能加不定冠詞 "an"。
×There are many electricities in this circuit.
✓There is a lot of electricity flowing in this circuit.
"electricity" 是不可數名詞，沒有複數形 "electricities"。表示大量時，應使用 "a lot of" 或 "much" 等詞。
×The electricity cut off yesterday.
✓The electricity was cut off yesterday. / There was a power cut yesterday.
表達「停電」時，電力是「被」切斷的，應使用被動語態 "was cut off"，或使用名詞片語 "power cut/outage"。
×I save the electricity by turning off lights.
✓I save electricity by turning off lights.
在表達「節省電力」這個一般概念時，"electricity" 前面通常不加定冠詞 "the"。
×This machine works with electricity.
✓This machine runs on electricity. / This machine is powered by electricity.
雖然 "work with" 語法上沒錯，但描述機器「以電力驅動」時，更地道的搭配是 "run on" 或 "is powered by" electricity。
×The bill for electricity is expensive.
✓The electricity bill is high. / Electricity is expensive.
形容「帳單」金額高用 "high"，形容「電費」貴用 "expensive"。通常直接說 "electricity bill" 更簡潔。
