Question

4．Are you concerned about the effect of the haze（雾霾） in Singapore on the health of your children？Then you should read the following passage．
"Young children，especially those with lung or heart illness，should avoid outdoor activity at PSI（Pollution Standards Index---used in Singapore） levels above 100，"says Dr Biju Thomas．
The immune system（免疫系统） of children is not mature．（36）AExposure to the haze can result in symptoms such as a blocked nose，dry throat，breathing difficulty，and so on．
Children who are exposed to the haze and experience any of these symptoms which are not serious should recover on their own in time if they limit their exposure to the haze．（37）CTo keep children safe during the haze in Singapore，parents should keep doors and windows closed at home．Ensure children drink plenty of pure water every day．（38）G
 The answer is that there aren't any N95 masks designed for use by children．That's because these masks are made to create a seal（密封） around the mouth and nose of the adult user so particles（颗粒） can not get in．（39）DSurgical masks may not offer enough protection from the harmful particles in the haze，which is very small （2.5 microns or less）．There is usually some gap between the surgical mask and the face，through which the haze particles may easily get in．（40）FHowever，if it is necessary to take children outdoors during a haze，parents may wish to offer children's surgical mask to their children，if it brings them comfort，such as filtering out the smell from the haze．

A．So during a haze，children are especially at risk．
B．Allow children for regular travels from one building to another．
C．However，if the symptoms continue，they should ask a doctor for help．
D．The available N95 masks may not fit tightly on the face of a child．
E．So you can use a conditioner instead of opening the windows regularly．
F．So it is best to keep children indoors to protect them from the haze when the PSI is high．
G．Are N95 masks and surgical masks suitable for children？

Answer 1

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了雾霾的影响和个人防治雾霾的一些方法．

解答 36．A．推理判断题．根据前文"The immune system（免疫系统） of children is not mature"，儿童的免疫系统是不成熟的，可以推测因果关系，因此在一次阴霾中，孩子们特别有风险；故选A．
37．C．推理判断题．根据前文"which are not serious should recover on their own in time if they limit their exposure to the haze"，如果他们限制暴露在烟雾中，他们没有严重的症状，他们会在自己的时间内恢复，根据前后文转折关系，应选，但是，如果症状继续，他们应该向医生寻求帮助；故选C．
38．G．推理判断题．根据后文The answer is that there aren't any N95 masks designed for use by children可知提出疑问N95口罩和外科口罩适合儿童吗；故选G．
39．D．推理判断题．前一句"That's because these masks are made to create a seal（密封） around the mouth and nose of the adult user so particles（颗粒） can not get in"这些面罩是单独针对大人设计的．故选项D"可买到的N95口罩可能与孩子的脸部贴合不太紧密．"符合语境；故选D．
40．F．推理判断题．根据前文There is usually some gap between the surgical mask and the face，through which the haze particles may easily get in可知最好是让孩子在室内保护他们免受阴霾影响；故选F．

点评 考察学生的推理判断能力和联系上下文的能力，在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．此类的填空题一定要联系上下文，根据上下文的内容加上自己的理解，再作出正确的判断．
