【参考答案】

III. 1. B. The national park covers 4,269 square kilometers, or one-seventh of the island. More than 95 percent of the park is virgin (原始状态的) forest and is home to 3,653 species of vascular plants (维管植物) and 540 species of terrestrial vertebrates (陆生脊椎动物).

由第三自然段内容可看出本段是对公园情况的一个介绍，因此答案选B。

2. A. The park is the only habitat (栖息地) of the world’s most endangered primate (灵长类动物) – the Hainan gibbon (长臂猿).

根据the only habitat可以判断海南长臂猿只生活在海南，故选A。

3. C. The number of Hainan gibbons has increased from fewer than 10 in the 1980s to 36 in 2022.

细节题，海南长臂猿在2022年增加到了36只。

4. D.  If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, cycas hainanensis plants over 10 years old blossom (开花) and bear fruit almost every year, thanks to the warm and humid (湿润的) weather.

细节题，由文中可知，海南苏铁在长江流域和中国北方几乎不开花不结果，在海南由于温暖湿润的天气却能开花结果，所以这种植物在温暖湿润的气候中会生长得更好。

因此答案选D。

5. A. This shows China’s achievements in environmental protection.

第四段最后一句表明中国在环境保护上取得了成就，故选A。

IV. A. 1. wonderland 2. concentrating 3. cover 4. endangered 5. destroyed 6. Two-thirds

B. BACED

C. DBABBC
