完形填空。

Are you carrying too much on your back at school? Lots of kids at the same age are as you are.      Not only are students in China     1     from this problem,but kids in the United States are     2     fed up with(飽受……之苦) heavy school bags.       Experts are starting to     3      that more and more young students are having back and neck problems as a result of school bags     4     too heavy for them.      "It's hard for me to get up the     5      with my bag because it's so heavy," said Rick Hammond,     6    ll-year-old student in the US.       Rick is among the students who have      7      backpacks(背包) with two straps(帶子) to carry them,     8      a number of other students choose rolling backpacks.      But even with rolling backpacks,    9    up stairs and buses with them is     10     a problem for kids. Many of them have hurt their knees,backs or necks because of heavy school bags.       But how much is too   11 ? Experts say students should carry     12      more than 10 to 15 percent of their own body weight.       Scott Bautch,a Wisconsin     13     docotor,said kids under4th grade should     14      within 10 percent. But it's also important that older kids don't go     15     15 percent,because their bones are still growing.      Bautch explained that there are other injuries caused by backpacks. "Kids are     16     their balance and falling down with these backpacks,"he said.       Parents and teachers are starting to tell the kids to only take     17      library books they will be reading that night.Some teachers are using worksheets (作業(yè)紙) or    18    workbooks for students to take home.       One of the best answers is,as some     19      themselves suggested, to have no homework    20    !
