Long-term is about a long stretch of time — either something that lasts a long time, or something that belongs to the far future rather than this week. A long-term plan is about months or years from now. A long-term contract lasts a long time.

Long-term is about講的是 a long stretch of time一長段時間—— either要嘛是 that lasts a long time持續很久的 something東西， or要嘛是 rather than this week不屬於這個星期、 that belongs to the far future而屬於較遠未來的 something東西。 A long-term plan長期計畫 is about講的是 from now從現在算起 months or years幾個月、甚至幾年之後的事。 A long-term contract長期合約 lasts會持續 a long time很長的時間。

Doctors talk about long-term effects: what a medicine, a habit, or an injury does to you over years, not just tomorrow. You will also hear long-term memory, long-term care, and a long-term relationship.

Doctors醫生 talk about會談 long-term effects長期影響： a medicine一種藥、 a habit一個習慣 or an injury或一次受傷， over years經年累月 what does to you對你做了什麼， not just tomorrow而不只是明天。 You will also hear你還會聽到 long-term memory長期記憶、 long-term care長期照護 and a long-term relationship和長期的感情關係。

The opposite is short-term. People use the word in two close ways, and both are normal: 'this will go on for a long time' and 'this is about later, not now.' It can sit before a noun (long-term plans) or after a verb (think long-term). It is the time-scale word.

The opposite相反詞 is是 short-term。 People人們 in two close ways用兩種很接近的方式 use the word用這個字， and both are normal兩種都正常： “this will go on for a long time”「這會持續很久」 and和 “this is about later, not now.”「這講的是以後，不是現在」。 It它 can sit可以放在 before a noun名詞前面 (long-term plans)， or after a verb或動詞後面 (think long-term)。 It它 is是 the time-scale word講時間尺度的那個字。

It is not quite the same as long-time, which more often describes a person who has already been something for years.

It它 as long-time和 long-time is not quite the same不完全一樣： which more often describes long-time 比較常形容 for years已經好幾年 who has already been something一直是某個身分的 a person人。
