我国特有的或主要分布在我国的珍稀动物有_________多种。

（8分）如图a是我们教室用的饮水机，它的铭牌上标有：额定电压220W，加热功率550W，架势到85℃﹣95℃．内部电路图可简化图b，把它接在教室的电路中，正常工作时保温状态的电流是0.2A，求：

（1）保温时饮水机的电功率是多少？

（2）当它处于加热状态时，若消耗的电能全部转化为内能被水吸收，它使热水罐中0.5kg，20℃的水的温度升高到90℃，要消耗多少电能？已知水的比热容是4.2×10³J/Kg•℃）．

（3）电阻R₁的值是多少？

（4）若冬季的加热时间与保温时间之比是1：5，求冬季每小时它消耗多少电能？

     [1]Medical research is leading American education officials to consider having high school classes start

later in the morning. The research says that teenagers are more awake later at night than adults are. When

staying up late at night, the teenagers have problems learning early in the morning.

     [2]Researchers in the state of Rhode Island measured the amount of the hormone (荷尔蒙) melatonin

(降黑素) in people's mouths at different times of the day. Melatonin causes people to feel sleepy.

     [3]They found that melatonin levels rise later at night in teenagers than they do in children and adults. It

remains at higher levels in teenagers later in the morning. They said this shows that teenagers have difficulty

learning early in the morning. Yet most school systems in the United States begin high school classes at about

seven o'clock.

     [4]A few school districts have made some changes. In 1996, school officials in Edina, Minnesota, changed

the start of classes from seven thirty to eight thirty. Two years later, the nearby city of Minneapolis did the

same. Teachers there reported that students were no longer sleepy in class and were happier. Staying in school

later in the day did not seem to be a problem for students who had jobs after school either.

     [5]Health experts say that teenagers need between eight and nine hours of sleep a night. Students _____ are

likely to be late for school, fail to do their homework, fall asleep in class and have trouble taking part in class

discussions.

     [6]Some people, however, don't support a later start time because they say that it would limit the time for

practicing sports after school. However, the Minnesota schools found that this did not hurt school sports

competitions.

     [7]More American school districts are discussing the possibility of changing high school start times.

Researchers and teenagers say that they cannot make the change quickly enough.
