分析 本文介绍了米族中的一员--菰米，菰米原产于北美，和稻米一样，菰米也是水生的，但是 它需要生长在较深的水域中，菰米不容易收割，所以价格较高，菰米对环境比较敏感，在美国随着水坝的增多，菰米的产量不比从前，这对喜欢吃菰米的人来说是个遗憾．
解答 46．actually；考查副词，分析句子结构可知此处用副词 actually在句中作状语．
47．is found；考查被动语态，grain与find之间是被动关系，且此处表示客观情况，故用一般现在时的被动语态is found．
48．deeper；考査形容词的比较级，结合语境分析句意为"和稻米一样，菰米也是水生的，但是 它需要生长在较深的水域中"，故填 比较级形式deeper．
49．that；考查固定结构，这里that与前面的so构成固定短语"so…that…"结构，意为"如此…以致于…"．
50．to harvest；考査固定结构，"It takes…to do sth．"意为"做某事需要…"．
51．from；考查介词，separate…from…是固定搭配，意为"使…与…分离"．
52．going；考查固定搭配，prevent …from doing sth是固定短语，意为"阻止…做某事"．
53．where；考查定语从句，分析句子结构可知这时应定语从句，先行词areas在从句中作地点状语，故用关系副词where．
54．a； 考查不定冠词，pity在此意为"遗 憾的事"，是可数名词，且在此表泛指，故答案为a．
55．production；考查名词，定冠词the后面要跟名词形式，故空格处应填名词production （生产）．
点评 首先要通读全文，了解大意，抓住上下文语境所提供的信息，仔细分析带空格的句子，明确空格所要填的词义，词型和短语搭配，给出所要填的正确形式，然后整体阅读短文，核对答案．
