你,或你的同事可能看到过这个孩子多次。他打嚏,气紧和混身发痒。他接连着感冒。他由于支气管炎,细支气管炎或肺炎等等情况可能曾经住过医院。父母变得忧虑,烦脑和失望。他们甚至可能已经联系好医生,或正进行联系。现在,也许被你想到的这个孩子确实不可能为变应性的,以至可能说出他的症状。 You, or your colleague, may have seen this child many times. He sneezed, gas tight and itchy. He caught the flu. He may have lived in a hospital because of bronchitis, bronchiolitis or pneumonia. Parents become worried, annoyed and disappointed. They may even have contacted a doctor or are in the process of getting in touch. Now it may be impossible for the child, whom you think of, to be allergic and possibly to speak out his symptoms.
