【 解析】leave sth. +地點“把某物忘在某處”
forget意為“遺忘某物”，指忘記一件具體的東西，但不能有具體的地點。
i left my book on the desk. i forgot my umbrella yesterday .
【辨析】leave 與forget的用法:
(1) leave “ 遺留，落下，忘記帶”，側重指把某物或某人留在某個地方，后常跟地點狀語；
（2）forget “ 忘記”，側重指忘記某件事情，后常跟to do (忘了要去做)或doing (忘了做過)。
【拓展】♦leave → left → left v 離開
(1)leave sth +地點 把某物遺忘在某地 (2)leave for +地點 離開去某地
(3) leave a message 留言 ask for leave 請假 leave school (中學) 畢業
(4)leave one by oneself=leave sb alone 把某人單獨留下
【注意】英語中表示“把某物遺忘在某處”常用 leave + 地點
而不是forget+地點 unluckily, i left my book at home
【延伸】動詞leave 的第三人稱單數形式為leaves; 而名詞leaf的復數也是leaves.
【江蘇無錫】i didn’t realize i __________(leave) the key at home until i got to my car. so i had to go back.
