Answer 1

分析 本文告诉我们恐高症是一个很正常的现象，在一定程度上它可以保护我们远离危险，但是在一定的安全环境下恐高就需要治疗，文章提到了两者治疗方式：一是要患者认清自己的恐惧，鼓励他们去高一点的建筑上去；二是教他们通过深呼吸等方式去控制恐惧感．

解答 61．exists；考查动词的时态，本文陈述一个事实，要用一般现在时态，主语 the fear 为抽象名词，故动词用第三人称单数exists．  
62．to understand；考查动词不定式，此处不定式作主语，即to understand is easy．
63．the；考查冠词，这里用the放在other前面，与上文的one构成"one…the other…"结构．  
64．from/against；考查介词，protects sb  from/against 是固定搭配，意为"保护某人使不受…的侵害"．
65．which；考查定语从句，分析句子结构知这是一个非限制性定语从句，用which指代上文提到的内容．  
66．Fortunately；考查副词，此处用副词作句子的状语．    
67，be treated；考查动词的语态，此处主语this指代上文提到的 the fear of heights，与动词treat是被动关系，"恐高症是可以被治疗的"，故用被动语态 be treated．   
68．their；考查物主代词，这里用形容词性物主代词放在名词fear前面作定语．     
69．faced；考查省略句，原句应为when they are faced with a threatening situation…．
70 effective；考查形容词，系动词be后面跟形容词形式作表语，构成系表结构．

点评 语法填空题是考查学生对语篇的理解能力和语言知识的应用能力．解题时，要在理解文章的基础上，充分考虑语境和上下文的联系．运用所掌握的词汇，语法等知识进行作答．
