问题 In virtually all types of tissue in every animal species, dioxin induces the production of enzymes that are the organism’s trying to metabolize, or render harmless, the chemical that is irritating it.
选项 A、trying to metabolize, or render harmless, the chemical that is irritating it
B、trying that it metabolize, or render harmless, the chemical irritant
C、attempt to try to metabolize, or render harmless, such a chemical irritant
D、attempt to try and metabolize, or render harmless, the chemical irritating it
E、attempt to metabolize, or render harmless, the chemical irritant
答案E
解析 首先可排除B，因为try之后从不跟that从句。C、D中attempt to try属于“同义重复”。再进行A、E对比：trying显然不如attempt好，因为trying很少作动名词，更多的是作形容词“困难的”，而且the chemical that is irritating it明显不如the chemical irritant(注：irritant此处是名词)简洁。值得指出的是，or render harmless是插入成分，render之前省略了to，补全即为：to metabolize the chemical irritant，or to render harmless the chemical irritant。在这里harmless的位置前置，译为：使这种化学刺激物无害。
