Q.

Tickets to the party cost $24 each and are inclusive of dinner and drinks.

為什麼不能選 inclusion？

A. 2017/11/24

單看一般的句法，are + 形容詞 (inclusive) 或名詞 (inclusion) 都有可能。不過，原句可以從連接詞 and 拆開成兩部分，這兩部分意義都要合理，而且主詞都是 Tickets：

(1) Tickets to the party cost $24 each.

(2a) Tickets to the party are inclusive of dinner and drinks.

慣用詞 [inclusive of X] 意思是包括 X 在內。例如：

The rent is inclusive of water and heating. (牛津字典) 租金內含水費及暖氣費。

Tickets to the party cost $24 each and are inclusive of dinner and drinks.

如果選填 inclusion，會使得 (b) 變得邏輯不通：

(2b) Tickets to the party are inclusion of dinner and drinks. (?)

[Tickets…are inclusion] 意思變成票是包括在內的項目，彷彿有個更大的東西，裡面包含了票啦、飲料啦、食物啦等等。

如果還是想用 inclusion，句子得改寫，例如：

(2c) Dinner and drinks are inclusions in the tickets.
