6. 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.
(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
Although an "-ing" verb such as trying can sometimes be used as a noun, the phrase the organism's trying to metabolize in A is unidiomatic because trying is used as the object of organism's. In B, trying that it metabolize is ungrammatical. The noun attempt could follow organism's; also, it would parallel the noun enzymes, and parallelism is needed here because the sentence uses the linking verb are to equate enzymes and attempt. In C and D, however, attempt to try is redundant. Choice E, which says attempt to metabolize, is best. The phrase the chemical irritant is also the most concise and precise conclusion for the sentence because it clearly refers to the dioxin mentioned earlier.
我是個菜鳥,對於SC很弱,想請教:
OG對B選項的解釋,是attemp當名詞可與enzyme平行, 而trying則不行
因為抽象名詞優於動名詞或是分詞的緣故嗎??
