2008夏季，第29屆奧運會將在北京舉行．為辦好這屆奧運會，北京奧組委提出了“綠色奧運，科技奧運，人文奧運”的理念．“綠色奧運”將成為北京奧運會的一大特色．
①能源環保方面的綠色：
a、北京奧運會火炬燃料選擇了丙烷（C₃H₈），其燃燒過程中不易產生黑煙．符合“綠色奧運”的主題．寫出丙烷燃燒的化學方程式：；
b、三聚氰酸C₃N₃（OH）₃可用于消除汽車尾氣中的氮氧化物（如NO₂）．當加熱至一定溫度時，三聚氰酸將分解生成HNCO（異氰酸，其中N為-3價），HNCO能和NO₂在受熱時能反應生成N₂、CO₂和H₂O．
請完成上述兩個反應的化學方程式：、HNCO+6NO₂?7N₂+CO₂+H₂O（填寫化學計量數，共1分）；
c、在奧運場館周圍，分布著一些奇怪的廁所--便池里面一堆泡沫，不需要水沖洗．這樣的廁所有什么實際意義？；
②運動營養補劑方面的綠色：諾龍是一種常見的興奮劑，化學式是C₁₈H₂₆O₂，它可以起到增加肌肉強度和豐滿度的效果．則：
a、諾龍分子中，C、H、O原子個數比為；
b、g丙烷（C₃H₈）中所含碳元素質量和54.8g諾龍中所含碳元素質量相等．
③人文奧運：
北京奧組委為體操運動員提供了優質的“鎂粉”，以增加摩擦力．已知“鎂粉”是一種含鎂的化合物，且能和鹽酸反應生成CO₂，該“鎂粉”可能是（填化學式）．

第三部分：閱讀理解（共20小題，共40分）
第一節（共15題, 每小題2分，滿分30分）
閱讀下列短文，從每題所給的四個選項（A,B,C和D）中，選出最佳選項。                              
A
What secret force drives us into the arms of one person, while pushing us away from another who might appear equally desirable to any fair observer? Of the many factors influencing our idea of the perfect mate, one of the most telling is our “lovemap” ---- a group of messages formed in our brains that describes our likes and dislikes．It shows our preferences in hair and eye color, in voice, smell, body build．It also records the kind of personality that attracts us, whether it’s the warm and friendly type or the strong silent type．In short, we fall for and go after those people who most clearly fit our lovemap．And this lovemap is determined in childhood．By age eight, the pattern for our ideal mate has already begun to float around in our brains．
The mother has special influence on her sons: she not only gives them clues to what they will find attractive in a mate, but also influences how they feel about women in general．So if she is warm and nice, her sons are going to think that’s the way women are．They will likely grow up warm and responsive lovers and also be helpful around the house．
Just as mothers influence their son’s general feelings toward women, fathers influence their daughter’s general feelings about men．If a father lavishes praise on his daughter and shows that she is a worthwhile person, she’ll feel very good about herself in relation to men．But if the father is cold, critical or absent, the daughter will tend to feel she’s not very lovable or attractive．
While the mother determines in large part what qualities attract us in a mate, it’s the father ----- the first male in our lives ----- who influences how we relate to the opposite sex．Fathers have a great effect on their children’s personalities and chances or marriage happiness．
56．What is the proper title for this passage?
A．Why we love who we love           B．What is a lovemap
C．Different influence from parents        D．Ideal mate in the mind
57．A perfect mate is a person who ____．
A．is fair to everyone               B．is the most desirable
C．fits one’s lovemap               D．is perfect in everything
58．If the husband hardly does any housework, ____．
A．his mother must be warm             B．his father must be critical
C．his mother must be cold               D．his wife can’t be attractive
59．The passage leads to a belief that ____．
A．parents’ personalities decides the children’s lovemap
B．mothers have no influence on daughters’ marriage life
C．fathers care more about children’s marriage happiness
D．mothers influence children’s choices of perfect mates
