6．For foreigners，entering a public toile t in China can be a horrifying experience．In the 1990s，a third of all complaints to tourism officials in Beijing concerned the design，and the bad smell of public toilets．
China has battled smelly toilets for at least 2，000 years．In the Kingdom of Wei （220-266 A．D．），visitors to the palace bathrooms would find boxes to cover their nose and ward off unpleasant smells．Both flushing （沖水） toilets and toilet paper were invented in China，however，only for the use of the emperor．
Today Chinese scientists have claimed victory in their battle to improve public restrooms，introducing a bacterial spray that can almost get rid of all the bad smell．First，a set of six types of bacteria work to break down the smelly compounds and then a perfume made from orange skin lightly scents （使芳香） the air．The"smellfree toilet"study from the Chinese Academy of Science was declared the"ultimate"cure toan"urgent"national issue．
"Five scientists have worked on this from 2011 to the beginning of this year，"said Dr．Yan Zhiying，a bacteriologist with the academy's Chengdu Institute of Biology，adding that they had spent￡140，000 on the project．
"Some local government officials here visited a sewage （污水） plant and saw that the treatment technology had come from Japan．They wanted a homegrown solution so they asked us to work on it，"he added．"We obtained bacteria from all types of waste from humans，pigs，chicken and duck s，and we tested our compounds one by one，"he said．"The smells coming out of public toilets，or trash cans，are made up of more than 160 different compounds，"he explained，adding that their bacteria spray can change and absorb many of them．
He boasted that the Chinese formula （配方），which costs only around￡5 per liter，has no side effects and can be used to remove any bad smell．

分析 這是一篇說明文，介紹的是中科院成都生物研究所發(fā)明了一種細菌噴灑劑，能夠出去廁所臭味，還能使廁所具有芳香味．
解答 25．D．猜測詞義題．根據(jù)句子visitors to the palace bathrooms would find boxes to cover their nose 從句意來看，游客用紙盒子把鼻子蓋住，顯然是為了把難聞的臭味"擋在外面"，故選A項．
26．A．推理判斷題．全文的焦點是中國公廁的臭味難聞，現(xiàn)在中科院進行"無味廁所"研究，可以推斷出這個全國性的緊急問題就是：廁所的臭味．故選C項．
27．A．細節(jié)理解題．解析：依據(jù)文章最后一段句子He boasted that the Chinese formula （配方），which costs only around￡5 per liter，has no side effects and can be used to remove any bad smell中提到的優(yōu)點只有前三項，而沒有漂亮的設(shè)計這項，故選A．
28．B．推理判斷題．依據(jù)第一段In the 1990s，a third of all complaints to tourism officials in Beijing concerned the design，and the bad smell of public toilets．
可知游客關(guān)于"公廁的臭味問題"的投訴占三分之一，由此可以推斷：這種除臭劑在中國的公廁中噴灑后，游客的投訴抱怨會減少．故選C項．
點評 本篇閱讀測試考生在閱讀基礎(chǔ)上的邏輯推理能力，要求考生根據(jù)文章所述事件的邏輯關(guān)系，對未說明的趨勢或結(jié)局作出合理的推斷；或根據(jù)作者所闡述的觀點理論，對文章未涉及的現(xiàn)象、事例給以解釋．考生首先要仔細閱讀短文，完整了解信息，準確把握作者觀點．
