1.[D]事实细节题。本题考查对复合句的理解。本题涉及两个段落，第2段及第3段都提及昆虫大量生长的地方，第3段第3句中的Theoneplace指出了答案。

2.[B]事实细节题。本题考查对复杂句的理解。第4段第1句指出了答案。protect…from…是对resistantto的同义替换。

3.[B]推理判断题。本题考查对长句的理解。最后一段第2句中的nearlyinvisible表明昆虫伪装是为了不被发现，因此B为正确选项。其他选项虽然都是昆虫伪装的目的，但都与伪装成自然物体无关。

4.[D]推理判断题。本题考查对含有分词结构句子的理解。根据第2段倒数第2句中的useful及分词结构pollinating可推断昆虫对植物的生长有益处。选项A、B、C中都有any,过于绝对。由第3段第2、3句可知选项A不对。文章虽在开头指出昆虫存活的年代久远，但全文未提到它是存活时间最长的生物，所以选项B错误。至于昆虫的食物，第3段倒数第2句有提及,但只是awiderangeof,由此可排除选项C。

5.[B]主旨大意题。本文前两段首先描述了昆虫生存了很长的时间，并能在各种地方生长，然后引出文章要讨论的重点，即昆虫为什么能成功存活。第3段第1句为本文的中心句，因此本题正确选项为B。
