答案：A偏二甲肼（CH3-NH-NH-CH3）中C为-2价，N也是-2价，四氧化二氮（N2O4）中N是+4价，二氧化碳中C是+4价，根据化合价的变化，可判断出，偏二甲肼被氧化为氮气和二氧化碳，四氧化二氮被还原为氮气。所以偏二甲...

| 任楠与夏祎都是新时代的年轻人，非常在意享受高品质的生活，并打算过一辈子的两人世界。作为高品质生活的需要，他们要求至少要有高品质的住宅、经济型的私家轿车、体面而舒适的服装、丰富的文化娱乐生活、适量的体育保健活动以及经常的旅游休闲安排。 一、案例成员
1．收入情况 (1)丈夫任楠，月工资5000元，每隔半年度有业务奖金约3万元； (2)太太夏祎，月工资3500元，收入与业绩挂钩，2007年年底夏祎获得奖金5万元。 2．支出情况 (1)住宅开支情况 ①3年前任楠与夏祎还未结婚共同生活时，以每个月3000元的高价在朝阳路一个高档单身公寓租住了一套50平方米的一室一厅。 ②在2007年初任楠与夏祎商量着在海淀区购买了一套68平方米的两室一厅，每平方米13000元，并向银行申请了八成20年期贷款，那次付首期几乎用光了任楠与夏祎的全部积蓄。在还款方式上他们就选择了等额本金还款法。这套新房买了后，由于一时无款装修，房子离工作单位也较远，就一直空置在那里。 (2)交通开支情况 2006年底，任楠就与夏祎向银行申请了一笔五成5年期贷款(也是办理等额本金还贷方式)购买了一台价值16万元的经济型轿车。车贷月还款额一项还不是太大的开支，真正的开支还有用车、养车的日常费用，每年仅养路费、保险费等固定开支就达12000元，汽油费、过路费、停车费、维修保养费等，平均每个月还得花费1000元左右。 (3)基本生活开支情况 ①物业管理费每个月250元，水电煤气费300元，电话通信上网费450元，卫生用品 200元，日常生活饮食用品500元，日常文化体育娱乐开支500元，这样平均每个月的日常生活开支约需2200元。 ②夏祎每年购物、美容、交友还得开支约1万元，任楠每年打球、运动、交友以及泡吧也得花去1万元，每年两人一同外出旅游或者节假日到北京周边休闲旅游大约要支出1万元，加上购买或更新手机、电脑等较大件消费品每年约需1万元。 三、保险状况 1．任楠有很强的风险保障意识，两年前他为自己购买了一份50万元保额的终身寿险，缴费期限20年，每年需缴纳5000元左右； 2．夏祎购买了一份保额30万的终身寿险，缴费期限20年，年缴保费3000元左右； 3．公司每月为任先生缴纳的社保为500元，公司每月为任太太缴纳的社保为350元，拥有一定的医疗保障和养老保障； 4．二人购买了一份保额10万元的健康保险，每人年缴5000元左右，缴费期限20年。 四、家庭资产负债状况 2005年，夏祎所在银行为了鼓励员工买房，为员工提供了一项福利，根据员工的级别、工作年限等标准给予不同额度的内部优惠贷款，只需两位同事担保即可获得贷款，利率只有3.8%。面对这一好政策，夏祎所在行的同事纷纷贷款买房或者用于其他投资，夏祎也根据自己的标准申请了一笔总额20万元的员工贷款，按等额本息法分20年还清。本来，这笔钱夏祎是准备用来买房的，但是任楠却将钱投进了股市，但由于未能掌握投资时机，这笔投资差不多缩水了一半。根据总行最新的文件规定，所有的员工内部贷款自2008年起一律取消优惠利率，执行正常房贷利率5.508%。 现在，任楠与夏祎手中基本上没有什么存款和积蓄，每个月都要为应付来自各个方面的账单而发愁，每个月的房租、管理费、生活费、车贷、房贷、员工贷款、个税、应酬让两人疲于奔命，两人各申请了一张30000元额度的信用卡，经常需要靠信用卡的透支款来应付紧张的资金周转困难。 五、家庭理财目标方面 对于任楠与夏祎来说，当前最紧迫和最重要的理财目标是通过合理的现金规划，在尽量不降低当前生活品质的情况下，首先实现收支平衡，尽快改变目前的“负翁”状态和长期为还款而捉襟见肘、东借西支的窘境。然后再通过科学的投资规划使家庭年度结余从负数到有盈余。 六、假设条件 假设2007年个人所得税扣除标准为每月1600元，2008年个人所得税扣除标准为每月 2000元。 |
2007年任太太共纳税( )元。
A．7375
B．8175
C．8635
D．8935

For Chinese students the end of their senior year is filled with studying and stress as they prepare for
the college entrance exams in June. But for American high school seniors the experience couldn't be more different. The end of senior year is a celebration of their time in high school and involves parties, games
and fun.
Senioritis is a commonly used expression. It means seniors have a disease which makes them unable
to do work. This starts in April when seniors find out where they have been accepted to university.
Unwilling to do school work, seniors have plenty of other activities to focus on. Many schools have
a "Senior Show", in which only seniors are allowed to perform. Some seniors sing or dance but many of
them perform skits (滑稽短剧), where they make fun of their favorite teachers or their friends. For
example, a group of boys may dress up and imitate a group of their girl friends. It is all very light-hearted.
The "Senior Show" is usually a part of Senior Week, which is a week specifically dedicated (专用的)
to seniors. During this week, seniors usually get academic or athletic awards they have won over their
high school careers. The seniors also vote for one of their male and female classmates who they believe is
the best-looking or funniest or most involved, etc. These are then published in the yearbook.
The yearbook is an important part of high school for seniors. It is usually dedicated to them and has all
their pictures and a quote from them in it. Then seniors go around and get it signed by their friends so they can always remember their time together.
Of course during all of this time, seniors are preparing for the Senior Prom, which is an important
moment in American culture. It is the most important dance in a young American's life.
The end of senior year is a truly special and wonderful time for American students. It's something they
will remember for the rest of their lives.
