　　六级仔细阅读专项训练答案

　　1.[the rapid discovery of its cure]

　　[定位]根据题干中的Robert Weinberg和causes查找到第1段第2句。

　　解析：题干warns对应原文cautions，转折词But表明Robert Weinberg认为，这些人的想法是错的，即他并不认为找到了癌症的成因就能很快的找到该癌症的治疗方法(the rapid discovery of its cure)。

　　2.[there are 120 varieties of cancer in existence]

　　[定位]根据题干中的how cancer works查找到第3段第1句。

　　解析：原文中的discovering对应题干中的find out，填入的内容需在句首with...中找, because后接完整的从句，因此需补上there are。

　　3.[cancerous]

　　[定位]根据题干中的oncogenes查找到第3段最后一句。

　　解析：题干中的are at work和原文中的are driven into action属于同义替换，因此照搬原文becomes后的形容词cancerous即可。

　　4.[environmental factors]

　　[定位]根据题干引号内容查找到第4段最后一句。

　　解析：原文该句的前一个分句的内容说，环境因素永远无法彻底消除，而接下来海沃德的话也说明这一点。题干中that从句是对该段末句的后一个分句的近义改写。对比原文与题干，可知environmental factors为本题答案。

　　5.[counteract its action]

　　[定位]末段末句。

　　解析：题干中Provided引导条件句，相当于If;被动句the mechanisms of cancer are found out和原文understand howcancer works表达了相同的意思，在这种假设条件下，原文所说的结果是we can counteract its action，故counteractits action为答案。
