问题 It is a great (i)_____ to be able to transfer useful genes with as little extra gene material as possible, because the donor’s genome may contain, in addition to desirable genes, many genes with (ii)_____ effects.
选项 A、misfortune…unpredictable
B、disappointment…superfluous
C、convenience…exquisite
D、accomplishment…profound
E、advantage…deleterious
答案 E
解析 空格(i)：
- 方程等号：is，前后取同。
- 强词和对应：It引导形式主语，真正的主语为to be able to…的内容。transfer useful genes指向空格(i)，根据is取同，体现转移有用的基因是“有用的”，填入一个正向词misfortune不幸，disappointment失望，convenience便利，accomplishment成就，advantage优势。C、D和E三项合适。
空格(ii)：
- 方程等号：in addition to除了…之外还，前后取反。
- 强词和对应：desirable genes根据in additional to取反，所以空格填入一个负向词，unpredictable不可预测的(对)，superfluous多余的(对)，exquisite精致的(错)，profound深刻的(错)，deleterious有害的(对)。综合空格(i)，答案选E。
