24. _____ halfway between Hawaii and Australia, Tuvalu is threatened by rising sea levels.
(A) Be located
(B) Locating
(C) Has been located
(D) Located
(E) Has locating

locate 和 situate 通常在講「東西或建築物的位置」時會用被動語態：
• The temple is located in Kyoto.
• The hotel is situated near the beach.

這是因為建築物或地點「被放置在某處」，語意上傾向於被動

⸻

如果想改成 主動語態，可以考慮以下幾個替代動詞，依照語境來選：

1. stand
• 表示建築物「矗立、位於」
• 例句：The old castle stands on top of the hill.

2. lie
• 用來描述某個地方或地理位置「位於某處」
• 例句：The village lies to the north of the river.

3. occupy
• 用來強調「占據」某個空間
• 例句：The factory occupies a large area in the industrial zone.

4. extend
• 表示「延伸至某地」，常用於河流、建築、邊界等
• 例句：The Great Wall extends across northern China.
