1. 代名詞與先行詞的一致：代名詞與先詞在人稱、性別、單複數、人或物等方面應該要一致。1. 代名詞與先行詞的一致：代名詞與先詞在人稱、性別、單複數、人或物等方面應該要一致。
請將下列劃線部份訂正：
1. Dolphins(海豚) are warm-blooded(暖血的)；that is, its body temperature always stays the same. (指Dolphins，故改為their)
2. No person may enter the hall unless you get permission. (先行詞person為第三人稱單數，故改為he gets)
3. The scientist is busy with its research about how some animals can learn a language. (先行詞為scientist，故改為his或her)
2. 代名詞的累贅：
例：
1. Students should try to study hard. (主詞為students，故they累贅)
2. The train which travels through the forest. (which應去掉)
3. The house which I bought was expensive. (bought的受詞為which，故it要去掉)
