Question

4．Are you concerned about the effect of the haze（霧霾） 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（免疫系統(tǒng)） 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（顆粒） 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 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了霧霾的影響和個人防治霧霾的一些方法．

解答 36．A．推理判斷題．根據(jù)前文"The immune system（免疫系統(tǒng)） of children is not mature"，兒童的免疫系統(tǒng)是不成熟的，可以推測因果關系，因此在一次陰霾中，孩子們特別有風險；故選A．
37．C．推理判斷題．根據(jù)前文"which are not serious should recover on their own in time if they limit their exposure to the haze"，如果他們限制暴露在煙霧中，他們沒有嚴重的癥狀，他們會在自己的時間內(nèi)恢復，根據(jù)前后文轉(zhuǎn)折關系，應選，但是，如果癥狀繼續(xù)，他們應該向醫(yī)生尋求幫助；故選C．
38．G．推理判斷題．根據(jù)后文The answer is that there aren't any N95 masks designed for use by children可知提出疑問N95口罩和外科口罩適合兒童嗎；故選G．
39．D．推理判斷題．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（顆粒） can not get in"這些面罩是單獨針對大人設計的．故選項D"可買到的N95口罩可能與孩子的臉部貼合不太緊密．"符合語境；故選D．
40．F．推理判斷題．根據(jù)前文There is usually some gap between the surgical mask and the face，through which the haze particles may easily get in可知最好是讓孩子在室內(nèi)保護他們免受陰霾影響；故選F．

點評 考察學生的推理判斷能力和聯(lián)系上下文的能力，在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．此類的填空題一定要聯(lián)系上下文，根據(jù)上下文的內(nèi)容加上自己的理解，再作出正確的判斷．
