whether the students' illnesses have been minor because they're young and healthy or because it is a minor
strain（菌株）of the virus,Bloomberg responded,"We don't know."_________(56)
A:number
B:spread
C:size
D:amount答案：A解析：猪流感是swine flu，文中出现过多次。
从上下文得知，患病的学生中没有人住院，有一些已经康复，因此他们的症状应该是比较轻的，所以选B。
学校里的学生有了类似流感的症状，肯定是没能上学。
从上下文可以看出，纽约卫生官员检验了8名学生的血样后认为他们很可能是患上了猪流感。suffer from意为“患……病”。
疾病防控中心对纽约卫生官员的诊断予以证实。diagnosis是“诊断”的意思。
显然此处应为确诊的猪流感患者的数量：the number of confirmed swine flu cases。
从上文和接下来的“no sign”就可以推断出此处应为同样的表达方式。sign意为“迹象”。
其他学校没有暴发猪流感的迹象。
学校的一些学生是在墨西哥度的春假。spring break指春假，“度假”用动词spend。
从上下文可知，当局尚未确定被确诊为猪流感的学生中是否有谁去过墨西哥。
从上下文可知，去墨西哥旅游的人，有的自己可能没有表现出任何流感症状，但却把流感传给了其他人。
恋家的学生在症状消退后，继续在家待48小时。stay home意为“待在家里”。
接下来一句说，如果症状严重，人们应该去医院，因此前面的句子意思应该相反，即没 有必要上医院。There is no need to do sth．意为“没必要做某事”。
as with的意思是“和······一样，正如”。
从后面的“responded”一词可以推断出前面应该是“被问到”，即“Asked”。 -
