1. D。根据第二段的“Why can’t we stop the common cold? … the main challenge lies in the many different types of cold viruses that are produced by the rhinoviruses”可知普通感冒难以防治主要是源于鼻病毒所导致的感冒病毒的多样性，所以D为正确答案。
2. A。由文中的“All the viruses were unable to replicate (复制) inside cells without a gene that produces a specific protein called methyltransferase (甲基转移酶) SETD3. Then, they tested genetically (从基因方面) modified mice, which were completely unable to produce the protein. The mice were able to live healthy, normal lives without the protein.”可以推知，这种名叫甲基转移酶SETD3的蛋白质有助于促进病毒在细胞内复制，故答案为A。
3. B。根据“The mice were able to live healthy, normal lives without the protein.”“These mice would always die [without the mutation], but they survived and we saw a very strong reduction in viral replication and very strong protection.”可以推知B为正确答案。
4. B。根据倒数第三段的“Carette said the plan is to find a drug that can temporarily suppress (抑制) the protein, instead of producing genetically modified humans.”可知B为正确答案。

3. A。倒数第二段主要讲述了母亲是如何帮助作者塑造独特的自我身份特征，如夜里给作者读睡前故事，亲自教作者弹钢琴，通过这些方式挖掘了作者的兴趣和潜力，所以答案为A。
