Hong Kong gives me an eternal/ a perpetual/ an everlasting memory.
HONG KONG gave me to have eternity 这句话错, 是因为give 不作使动用法, 应该换成let, remember是动词, 不能当名词用.
可改为 Hong Kong lets/let me to have an eternal/ a perpetual/ an everlasting memory.
而用lets/let, 取决于时态, 前者为一般现在时, 后者为一般过去时.
Hong Kong gives me an everlasting memory.
'eternity' 係名詞,'remember' 係動詞
但'everlasting' 係形容'memory'
所以'everlasting' 應該要用形容詞,而'memory' 用名詞
