【解析】

试题分析：本文属于记叙文，介绍了小岛Virginia Key的生态环境恶化，志愿者在这里种植了很多的红树苗以保护环境。

【1】containing 考查分词用法。本句中动词短语“contain a variety of....”与名词island构成主动关系，所以使用现在分词短语做定语修饰名词a barrier island。

【2】is located 考查形容词短语。短语be located in...位于....；该短语在句中作为谓语。句意：Virginia Key位于Biscayne Bay。

【3】the 考查定冠词。在英语中定冠词“the”通常表示特指。本句中专有名词“the Atlantic Ocean”意为大西洋。

【4】has been 考查时态。本句的时间状语是since the 1970s，since引导的时间状语，通常都和现在完成时连用。所以本句使用has been。

【5】that/which 考查定语从句。本句中关系代词which/that指代先行词，在定语从句中做主语。

【6】Fortunately 考查副词。在英语中副词通常做状语修饰形容词、副词、动词或整个句子，而形容词通常做定语或表语修饰名词。本句中使用副词fortunately做状语修饰这个句子。

【7】by 考查介词。介词“by被....”用于被动语态，表示动作的发出者。句意：幸运的是在过去的五年里，志愿者种植了11,000棵红树苗。

【8】to monitor 考查不定式。本句中不定式在句中做目的状语。句意：志愿者们正在努力监控这块栖息地。

【9】growth 考查名词。横线前面有动词check，说明横线应该使用名词growth作为动词的宾语，且有定冠词the修饰，表示特指。

【10】if 考查连词。句意：如果你想参加，就请在这里签字。上下文之间存在着条件关系，所以使用连词if引导条件状语从句。
