题目解析

24、定位词undesira ble trait;loss;mutation。原文出题句：定位原文Section B第二段：But every time a single plant with a mutation is taken  from  a  larger population for breeding,much genetic diversity is lost.And sometimes the desirable mutations come with less desirable traits.For instance,the tomato strains  grown  for supermarkets have lost much of their flavour.参考译文：但是，每当从更大的种群中抽取一株有突变的植物进行育种时，许多遗传多样性就会丧失。有时，理想的突变会带来不太理想的特性。例如，为超市种植的西红柿品系已经失去了大部分风味。题干解析An undesirable trait such as loss of may be  caused by a mutation in a tomato gene.译文：番茄基因突变可能会导致缺失等不良性状。本题为举例考点，预判空格答案为名词。题干中的undesirable trait对应原文中的less desirable traits; loss of对应lost。答案为flavour flavor。

25、定位词modifying one gene;three times。原文出题句：定位原文C部分第一段第二句：For instance,they tripled the size of fruit by editing a gene called FRUIT WEIGHT,and increased the number of tomatoes per truss by editing another called MULTIFLORA.参考译文：例如，他们通 过编辑一个名为“水果重 量”的基因，将水果的大 小增加了三倍，并通过编 辑另一个名为“多花”的 基因，增加了每个桁架的番茄数量。题干解析：By modifying one gene in a tomato plant,researchers made the tomato three times its original。译文：通过修改番茄植株中的一个基因，研究人员使番茄的产量达到原来的三倍。本题为形容词考点，预判空格答案为名词。题干中的modifying对应原文中的editing;three times对应tripled。答案为size。

26、定位词vitamin C;China。原文出题句：定位原文C部分最后一段最后一句：They also  created another strain that is more salt tolerant -and has higher levels of  vitamin C.参考译文：他们还创造了另一种耐盐性更强、维生素C含量更高的菌株。题干解析：A type of tomato which was not badly affected by     ,and was rich in vitamin C,was produced by a team of researchers in China.译文：中国的一个研究小组生产了一种受影响不严重、富含维生素C的番茄。本题为动词考点，预判空 格答案为名词。题干中的not badly affected by对应 tolerant。答案为salt。
