　　1．convenience　空格中所填单词在句中作介词for的宾语。

　　2．where　此处是非限制性定语从句，修饰先行词Greece，关系副词where在从句中作地点状语。

　　3．using　"using lots of plastic"是动名词短语作主语。

　　4．as　as在此处表示"作为"。

　　5．the　the number of表示"......的数量"，符合语境。

　　6．thrown　宾语"empty plastic bottles"与宾补动作"throw away"之间是被动关系，故用其过去分词形式。

　　7．was recycled　主语"10% of plastic waste"是谓语动词动作recycle的承受者，故用被动语态；时间状语"in 2014"与一般过去时连用。

　　8．and　该句使用了"祈使句＋and＋陈述句"句型。

　　9．more practical　根据空格后的"than the bottles themselves"，可知用形容词比较级。

　　10．it　用it指代一个瓶子，"如果你把空塑料瓶切成两半，就成了花盆"。
