Aruba is an island (around Caribbean 要改為 lies in the southern Caribbean Sea). Look at the pictures, What a beautiful island it is. But now, Aruba (要加 is) also means(用 mean) a sport. As we know, Aruba is a famous sport. People all around the world play it. In Guangzhou ,this sport named(應改用: is called) aluba，IN the north of China ，IT named(is called) cut tree。In Hongkong，it named (is called) X-concern. Its a dangerous sport, but many students love it. Look at this picture, teachers (要加 are) also join(用 joining) in Aluba。In the end of our military training, we also aluba our training officer (officers 範指，要用復數). I think aluba is so dangerous that we should do as few (要用less 運動名詞不可數 ) as possible.
前面用aruba，但後面卻變了aluba，是否打錯?
已替更正好了。
