电动自行车已成为大众化的一种交通工具，在使用时人们经常遇到的问题是：一次充满电后行驶不能达到说明书的里程数．为探明原因，小明用家里的电动自行车进行了测试．他骑车在平直的路面上由静止开始运动，获得如图所示的速度和牵引力随时间变化的关系图象．

（1）由图可知电动自行车的运动特点是：　  　．7～12s它受到的摩擦力是　 　N．电动自行车匀速行驶100m克服摩擦力做功是　 　J．

（2）小明又在不同负重情况下沿同一路面进行了测试，得到了一次充满电的最大行驶里程如下表，由此可以看出负重与最大行驶里程关系是　   　．你认为产生这种现象的原因是　         　．

负重（kg）	60	80	100	120	140
一次充满电连续行驶最大里程（km）	20	16.7	14.3	12.5	11.1

（4）测试过程中，小明还发现随着刹车、启动的次数增加，其能量在变化，通过分析可知（   ）

A．电能利用效率增大，量程增大

B．电能利用效率降低，量程增大

C．电能利用效率增大，里程减小

D．电能利用效率降低，里程减小

（5）除了以上的两个原因外，你认为还有哪些因素会影响电动自行车充满电后的最大行驶里程．　    　．（写出一条）

How is it that siblings （兄弟姐妹） can turn out so differently? One answer is that in fact each sibling grows up in a different family． The firstborn is, for a while, an only child, and therefore has a completely different experience of the parents than those born later． The next child is, for a while, the youngest, until the situation is changed by a new arrival． The mother and father themselves are changing and growing up too． One sibling might live in a stable and close family in the first few years; another might be raised in a family crisis, with a disappointed mother or an angry father．

Sibling competition was identified as an important shaping force as early as in 1918． But more recently, researchers have found many ways in which brothers and sisters are a lasting force in each others’ lives． Dr． Annette Henderson says firstborn children pick up vocabulary more quickly than their siblings． The reason for this might be that the later children aren’t getting the same one-on-one time with parents． But that doesn’t mean that the younger children have problems with language development． Later-borns don’t enjoy that much talking time with parents, but instead they harvest lessons from bigger brothers and sisters, learning entire phrases and getting an understanding of social concepts such as the difference between “I” and “me”． 

A Cambridge University study of 140 children found that siblings created a rich world of play that helped them grow socially． Love-hate relationships were common among the children． Even those siblings who fought the most had just as much positive communication as the other sibling pairs．

One way children seek more attention from parents is by making themselves different from their siblings, particularly if they are close in age． Researchers have found that the first two children in a family are typically more different from each other than the second and third． Girls with brothers show their differences to a maximum degree by being more feminine than girls with sisters． A 2003 research paper studied adolescents from 185 families over two years, finding that those who changed to make themselves different from their siblings were successful in increasing the amount of warmth they gained from their parents．
