They swim fast!”（它们能，但走得慢，游得快）是对该问题的回答，符合语境。 5. 答案：D 解析：上句询问“海豹有皮毛吗”，选项D“Yes, they have thick fur to keep warm.”（是的，它们有厚皮毛来保暖）是对该一般疑问句的肯定回答，符合语境。 八、【说明文】用所给单词的适当形式填空或根据上下文填入恰当单词。 1. 答案:are 解析：主语“Kingfishers”是复数，一般现在时中be动词用“are”。 2. 答案:countries 解析：“many”后接可数名词复数，“country”的复数形式是“countries”。 3. 答案:in 解析：“in danger”是固定短语，意为“处于危险中”。 4. 答案:dirtier 解析：“than”是比较级的标志词，“dirty”的比较级是“dirtier”。 5. 答案:so 解析：前句“河里没有鱼”是原因，后句“翠鸟没有食物”是结果，“so”表示“所以”，用于引出结果。 6. 答案:their 解析：此处修饰名词“nests”，要用形容词性物主代词，“they”的形容词性物主代词是“their”。 7. 答案:and 解析：“change the rivers”和“build new riverbanks”是并列的动作，用“and”连接。 8. 答案:to make 解析：“for sb. to do sth.”是固定结构，此处用动词不定式“to make”作后置定语，修饰“place”。 拓展练 九、【多模态】阅读理解。 1. 答案: T 解析：文中提到“Snow leopard...has thick gray fur with black spots, helping it hide in snow.”，与题干表述一致，故正确。 2. 答案: F 解析：文中指出“Rhinoceros...Many people kill them to get their horns”，而非为了皮毛，题干表述错误。 3. 答案:F 解析：文中说明“Orangutan...lives in rainforests. It eats fruits, leaves, and insects.”，并非生活在沙漠且吃肉，题干表述错误。 4. 答案:D 解析：文中提到“Snow leopard...living in high mountains”，因此雪豹生活在高山（High mountains），选D。 5. 答案:B 解析：文中指出“Rhinoceros...Many people kill them to get their horns”，犀牛濒危是因为人们为了牛角猎杀它们，选B。 6. 答案:C 解析：文中说明“Orangutan...eats fruits, leaves, and insects”，红毛猩猩吃水果、树叶和昆虫，选C。 7. We can plant more trees to make new homes for animals. We also can clean rivers and lakes to make safe water for animals.
