(1)小理用天平和量筒测量小石块的密度。他在调节天平时，发现指针偏向分度盘中央刻度线的右侧，如图甲所示。为使天平横梁水平平衡，他应将平衡螺母向端调。然后用调节好的天平测量小石块的质量，天平平衡时右盘中的砝码质量、游码在标尺上的位置如图乙所示，则小石块的质量是 g,用量筒测量小石块的体积如图丙所示，小石块的体积是 cm³,则小石块的密度是 kg/m³。

（2）小想要测薄厚均匀的长方形铜片的厚度，他从物质密度表中查出铜的密度是8.9g/cm³，这个密度值表示的物理意义是。然后，他用天平测量铜片的质量，天平平衡后，右盘所放砝码及游码位置如图所示。之后，他又用刻度尺测出这片铜片的长和宽，分别是20cm、5cm。运用这些数据，可计算铜片厚度为。

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(饱受……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(带子) 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 (作业纸) or    18    workbooks for students to take home.
      One of the best answers is,as some     19     themselves suggested, to have no homework    20    !
