1、不论以何种比例混合，将甲和乙两种混合气体同时通入过量的丙溶液中，一定能产生沉淀的组合是
A.①②③④ B．②③④⑤ C．②③④ D．①③④
【知识点】非金属元素的单质及其化合物
【答案】
2、现有X、Y、Z、W、Q五种短周期元素，原子序数依次增大，Y、Z、W、Q形成的简单离子具有相同的电子层结构，YX3、X2Z、X2Z2、W2Z、W2Z2都是常见的化合物，其中，YX3在常温下呈气态，能使酚酞溶液变红色．下列有关推断正确的是（ ）
A． 简单离子半径：Y＞Z＞W＞Q＞X
B． W2Z2与X2Z反应中氧化剂与还原剂物质的量之比为1：2
C． X能分别与Y、Z、W形成共价化合物
D． Y、W、Q的最高价氧化物对应的水化物两两之间一定相互反应
【知识点】物质结构 元素周期律单元测试
【答案】
考点： 原子结构与元素周期律的关系．
专题： 元素周期律与元素周期表专题．
分析： X、Y、Z、W、Q五种短周期元素，原子序数依次增大，Y、Z、W、Q形成的简单离子具有相同的电子层结构，YX3、X2Z、X2Z2、W2Z、W2Z2都是常见的化合物，YX3在常温下呈气态，能使酚酞溶液变红色，则该气体是氨气，所以X是H元素、Y是N元素，X和Z能形成化合物X2Z、X2Z2，则Z是O元素，W和Z能形成化合物W2Z、W2Z2，则W是Na元素，Q和W形成的简单离子具有相同的电子层结构，且原子序数大于W，则Q可能是Mg或Al，再结合题目分析解答．
解答： 解：X、Y、Z、W、Q五种短周期元素，原子序数依次增大，Y、Z、W、Q形成的简单离子具有相同的电子层结构，YX3、X2Z、X2Z2、W2Z、W2Z2都是常见的化合物，YX3在常温下呈气态，能使酚酞溶液变红色，则该气体是氨气，所以X是H元素、Y是N元素，X和Z能形成化合物X2Z、X2Z2，则Z是O元素，W和Z能形成化合物W2Z、W2Z2，则W是Na元素，Q和W形成的简单离子具有相同的电子层结构，且原子序数大于W，则Q可能是Mg或Al，
A．离子的电子层数越少，其离子半径越小，电子层结构相同的离子，离子半径随着原子序数增大而减小，所以离子半径大小顺序是Y＞Z＞W＞Q＞X，故A正确；
B．Na2O2与H2O反应中，氧化剂与还原剂都是过氧化钠，其物质的量之比为1：1，故B错误；
C．H能分别与N、O形成共价化合物，和Na形成离子化合物，故C错误；
D．N、Na的最高价氧化物对应的水化物分别是硝酸、NaOH，Q可能是Mg或Al，Q的最高价氧化物的水化物可能是氢氧化镁或氢氧化铝，氢氧化镁和氢氧化钠不反应，故D错误；
故选A．
点评： 本题考查了原子结构和元素性质，根据原子结构及元素之间形成的化合物特点确定元素，再结合元素周期律、物质结构、物质性质等知识点分析解答，注意Q元素可能是Mg或Al，根据题干不确定，为易错点．
3、下列反应的离子方程式正确的是
A．二氧化硫气体通入过氧化钠： 2SO2＋2Na2O2=== 2Na2SO3＋O2↑
B．金属铝投入NaOH溶液中：Al＋2OH－===AlO
＋H2↑
C．硫酸亚铁与酸性高锰酸钾反应：3Fe2＋＋MnO
＋4H＋ ＝ 3Fe3＋＋MnO2↓＋2H2O
D．碳酸氢钠溶液与少量石灰水反应：2HCO3-+Ca2++2OH-=CaCO3↓+CO32-+2H2O
【知识点】离子反应

3、 Tourism wasn’t as important as it is today. In the past, only people with a good deal of money could travel on holidays to other countries. More people travel today than in the past because there is a growing middle class in many parts of the world; that is to say, people now have more money for travel. Special plane fares(费用) for tourists make travel less expensive and more attractive than ever before. One person doesn’t travel for the same reason as another. But most people enjoy seeing countries that are different from their own. They also like to meet new people and to taste new food.
Tourism causes many changes in a country and in people’s lives. People build new hotels and restaurants and train native men and women as guides to show visitors interesting places. There’re new nightclubs and other amusements. International tourism is clearly a big business.
12. In the old days ______ could travel to other countries.
A. boys and girls, men or women, young or old B. either kings or queens
C. both the poor and the rich D. nobody but those who had money
13. What makes travel more attractive than before?
A. Travel by air to other countries is much cheaper today.
B. More guides are being trained to show beautiful spots.

14. Which of the following statements is true according to the article?
A. Tourism won’t bring any changes in people’s minds.
B. People have some trouble in making journey.
C. With the development of tourism, great changes have taken place in many parts in the world.
D. Tourism causes only some changes in clothing.
