1. A错. Essential 是形容词

2. C  but引导一个完整的句子, 其他3个成分都不完整.

3. B. 后半句是主句, 前面是If引导的条件状语从句.

4. D 定语从句啊.

1,such other
2,c.they have....unlike lizards是做状语的，插在中间
3,b,if the air is cool.....that are sun-warmed做定语从句
4,d,whose singing.....singing这里是歌唱的意思，whose singing combined powerfully vitality with great dignity做非限制性定于从句，用来描述Mahalia Jackson
