There was a blind girl who hated herself because she was blind. In fact, she 41 nobody except her boyfriend, for he was always 42 to help her. She used to tell her boyfriend, “If I could see the 43 , I would marry you. ”

　 One day, someone donated a pair of 44 to her. When the bandages（绷带）came off, she was able to see everything, including her boyfriend, for the 45 time. He asked her, “Now that you can see the world, will you 46 me?” The girl looked at her boyfriend and was greatly surprised to see that he was 　47 . She had never expected that．She would not like to be with a blind husband for the rest of her life，so she 48 to marry him．

Her boyfriend left in tears and a few days later wrote a 49 to her，saying，“My dear，take good care of your eyes． 50 they are yours. They were mine.”

　 This is how the human brain（人脑）often works when our status（地位）changes．Only a very few remember what 51 was like before．And we often ask for more than we need．Life is a gift. Today, before you complain about the 52 of your food，think of someone who has nothing to 53 . Before you complain about life，think of someone who went to heaven（天堂）too early. Before you complain about your old 54 , think of the people who are living in the streets．And when you are tired and complain about your job, think of those who have no jobs．So 55 what you have and don’t forget your past.

Imagine there is a bank that puts $ 86, 400 in your account ( 账户)each morning. It carries over no balance from day to day. Every evening the bank writes off( 注销)the balance that you failed to use during the day. What would you do? Take out every cent,  of course \
Each of us has such a bank. Its name is TIME. Every morning,  it puts in 86, 400 seconds. Every evening it writes off,  as it is lost. There is no balance or overdraft 透支) . If you fail to use the day’s savings,  the lost is yours. There is no going back. There is no taking from " tomorrow". You must make good use of it so as to get more in health,  happiness and success!
The clock is running. Make the most of today. To realize the value of ONE YEAR,  ask a student who failed a grade; To realize the value of ONE MONTH,  ask a mother who gave birth to a premature( 早产)baby; To realize the value of ONE WEEK,  ask the editor of a weekly newspaper; To realize the value of ONE HOUR,  ask the lovers who are waiting to meet; To realize the value of ONE MINUTE,  ask a person who missed the train; To realize the value of ONE SECOND,  ask a person who just avoided(避免)an accident.
Make good use of every moment that you have. Remember that time waits for no one. Yesterday is history. Tomorrow is a mystery. Today is a gift. That’s why it’s called "The Present".
【小题1】The underlined word "balance" in paragraph 1 means_________.

A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce(确保) bedtime. Instead, it may be that biologically(生物学上)these sleepyhead(贪睡者)students aren’t used to the early hour.
　　“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的)sleep at Brown’s School of Medicine.
　　Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level, she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns(方式).
　　Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
　　Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at night and sleep later in the morning. But it’s not just a matter of choice---their bodies are going through a change of sleep patterns.
　　All of this makes the transfer(迁移)from middle school to high school---which may start one hour earlier in the morning----all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescents are up against difficulties when they try to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
