问题 单项选择题

一类疫苗是国家根据目前国内疾病流行情况以及我国儿童的普遍身体状况规定的必须接种的疫苗,接种费用由政府支付,而其他不属于一类疫苗并且需要家长自费的疫苗属于二类疫苗。由此,家长们普遍认为,二类疫苗只是预防一类疫苗之外的疾病的。 以下哪项最能反驳家长们的看法?

A.二类疫苗中的五联疫苗可以预防一类疫苗已覆盖的一些疾病,因此可减少接种次数 

B.一类疫苗预防的是可能给孩子带来更大伤害的疾病,二类疫苗则不一定 

C.同一种疫苗在不同的国家和地区可能属于不同类型的疫苗 

D.选择不接种二类疫苗除了经济原因,还有对其安全性的考虑

答案

参考答案:A

解析:

解析

第一步:分析题干找到论点和论据论点是家长的看法:二类疫苗只能预防一类疫苗之外的疫病—二类疫苗预防的疾病与一类疫苗预防的疾病没有交集。论据是:一类疫苗必须接种,政府支付;二类疫苗家长自费接种。

第二步:逐一分析选项A项通过实例证明“二类疫苗中的某种疫苗可以预防一类疫苗已覆盖的一些疾病”即“二类疫苗预防的疾病与一类疫苗预防的疾病有交集”,直接否定了家长的看法。B项中提及到的疫苗的危害性以及D项中经济原因与家长看法没有联系属于无关项,排除。C项是可能选项,削弱力度较小,故A项最能反驳。
