答案及解析:
1. 【B】平行结构。本句中的谓语部分均是被动语态，为达到平衡与一致应选相同结构的选项。因此只有B正确。

2. 【B】exquisite: extremely beautiful or delicate; finely or skillfully made or done
Extravagant: (in the habit of) using or spending too much; (of actions) showing this tendency
Exotic: introduced from another country; not native
Eccentric: (of people, behaviour) unusual; peculiar; not conventional or normal

3. 【B】bluntly: in a blunt manner
Convincing: making you believe that something is true or right
Emphatically: If you say something emphatically, you say it in a forceful way which shows that you feel very strongly about what you are saying.
Determined: having a strong desire to do something, so that you will not let anyone stop you

4. 【D】非谓语动词用法。本句的谓语动词是 is found，其他动词应以非谓语动词形式出现。Owing to之后应接动名词，故A和B可以排除；主语aluminum与combine构成动宾关系，故应用被动语态，所以本题应选D。

5. 【D】a flash in the pan是固定搭配，表示“昙花一现”。
