因为 the 是表示特定、特指的,在此句中并没有特指的reservation, 是一般的高尔夫预定.举例子,i am eating an apple.这里有特指是什么苹果、或者哪个苹果吗?没有,所以用an 不用the.
i am eating the apple he gave me yesterday.这里就因为特指了是他给我的那个苹果(the apple he gave me),才用了the.
please confirm the reservation i made yesterday. 跟上面的例子道理一样,这里因为reservation后面有说明是i made yesterday(我昨天做的), 就是特指了.所以用the.
make a reservation、make a cake、take a nap 等等,都用a .
