题目:

(共12分)随着人类对温室效应和资源短缺等问题的重视,如何降低大气中CO2的含量及有效地开发利用CO2,引起了各国的普遍重视。

Ⅰ.目前工业上有一种方法是用CO2来生产燃料甲醇。为探究该反应原理,进行如下实验,在体积为1L的密闭容器中,充入1mol CO2和3.25 mol H2,在一定条件下发生反应,测定CO2、CH3OH(g)和H2O(g)的浓度随时间变化如下图所示:

(1)从反应开始到平衡,氢气的平均反应速率          mol/(L·min)

(2)该条件下CO2的转化率为            

(3)下列措施中能使n(CH3OH)/n(CO2)增大的是                   

A.升高温度

B.恒容时充入氮气

C.将水蒸气从体系中分离

D.用更有效的催化剂Ⅱ.下图是一个乙醇燃料电池工作时的示意图,乙池中的两个电极一个是石墨电极,一个是铁电极,工作时M、N两个电极的质量都不减少,请回答下列问题:

(1)M极的电极材料为             

(2)加入乙醇的铂电极的电极反应式为                                 

(3)在此过程中乙池中某一电极析出金属银4.32g时,此时乙池溶液的体积为400mL,则乙池中溶液的pH为           

(4)若在常温常压下,1g C2H5OH燃烧生成CO2和液态H2O时放出29.71kJ热量,表示该反应的热化学方程式为

Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier,have better marriages and have more respectable occupations. Personal consultants give them better advice for finding jobs. Even judges are softer on attractive defendants(被告).But in the executive circle,beauty can become a liability.

While attractiveness is a positive factor for a man on his way up the executive ladder,it is harmful to a woman.

Handsome male executives were thought as having more integrity than plainer men;effort and ability were thought to account for their success.

Attractive female executives were considered to have less integrity than unattractive ones;their success was attributed not to ability but to factors such as luck.

All unattractive women executives were thought to have more integrity and to be more capable than the attractive female executives. Interestingly,though,the rise of the unattractive overnight successes was attributed more to personal relationships and less to ability than that of attractive overnight successes.

Why are attractive women not thought to be able?An attractive woman is thought to be more feminine and an attractive man more masculine(有男子气概的)than the less attractive ones. Thus,an attractive woman has an advantage in traditionally female jobs,but an attractive woman in a traditionally masculine position appears to lack the “masculine” qualities required.

This is true even in politics. “When the only clue is how he or she looks,people treat men and women differently,”says Anne Bowman,who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduate students to rank two groups of photographs,one of men and one of women,in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again,in the order they would vote for them.

The results showed that attractive males utterly defeated unattractive men,but the women who had been ranked most attractive invariably received the fewest votes.

小题1:The underlined word “liability”(in Para.1)most probably means “________”.

A.misfortune

B.instability

C.disadvantage

D.burden小题2:In traditionally female jobs,attractiveness________.

A.reinforces(加强)the feminine qualities required

B.makes women look more honest and capable

D.often enables women to succeed quickly小题3:Bowman's experiment reveals that when it comes to politics,attractiveness________.

A.turns out to be an obstacle to men

B.affects men and women alike

C.has as little effect on men as on women

D.is more of an obstacle than a benefit to women小题4:It can be inferred from the passage that people's views on beauty are often________.

A.practical

B.prejudiced

C.old­fashioned

D.pessimistic小题5:The author writes this passage to________.

A.demand equal rights for women
