DNA sequencing could help conserve rare carp species
DNA 测序有助于保护珍稀鲤鱼物种
Chinese scientists (1) ______(assemble) successfully the chromosomal-level genome of the Ochetobius elongatus, a (2) ______ (rarely) fish species from the Yangtze River. It's the first time that such a high-quality genome at the chromosomal level and annotation information (3) ______ been obtained for this type of carp, which is a significant step (4) ______ restoring its fish population.
The achievement was made by a research team led by Professor Lu Jianguo from the School of Marine Sciences at Sun Yat-sen University along with researchers from the agricultural science institute of Jiujiang, Jiangxi province. Their research findings were published on Dec 19 in Scientific Data, a scientific journal under Nature.
The Ochetobius elongatus used to be an important freshwater economic fish in China and was (5) ______ distributed in the Yangtze River Basin. However, it has witnessed a sharp decline in population (6) ______ the past three decades because of environmental degradation and human activities, as Liang Xuanguang, co-first author of the research article, (7) ______.
To protect this endangered species, more efforts are needed. Scientists are expected to make (8) ______ use of the genome information to work out better conservation (9) ______ (plan). It's hoped that with these measures, the population of the Ochetobius elongatus will increase(10) ______(gradual) in the future.
答案：
have assembled （考查知识点：时态，根据语境用现在完成时，主语是 “scientists”，复数，所以填 “have”，表示已经完成的动作）
rare（考查知识点：词性转换，修饰名词 “fish species” 用形容词形式，“rare” 表示 “珍稀的”）
has（考查知识点：时态和主谓一致，“it is the first time that...” 从句中常用现在完成时，主语是 “information”，不可数名词，所以用 “has”）
for（考查知识点：固定搭配，“a step for...” 表示 “对于…… 的一步”，此处表示对于恢复鱼类种群来说是重要的一步）
widely（考查知识点：词性转换，修饰动词 “distributed” 用副词形式，“widely” 表示 “广泛地”）

said（考查知识点：时态，根据前文描述的情况，此处用一般过去时，“said” 表示 “说”）
full（考查知识点：固定短语，“make full use of...” 表示 “充分利用……”）
plans（考查知识点：名词单复数，“plan” 是可数名词，前面没有限定词，且根据语境用复数形式表示泛指的计划）
gradually
