Are you carrying too much on your back at school?I'm sure lots of children of your age will say“Yes”.Not only the students in China have this problem,but children in the United States also have heavy school bags.
Doctors are starting to worry that younger and younger students are having back and neck problems as a result of school bags being too heavy for them.
“It's hard for me to go upstairs with my bag because it's so heavy,”said Rick Hammond,an 11-year-old student in the US.
Rick is among students who have common school bags with two straps to carry them,but many other students choose rolling bags.
But even with rolling bags,getting upstairs and buses is still a problem for children.Many of them have hurt their backs and necks because of the heavy school bags.
But how much is too much?Doctors say students should carry no more than 10% to 15% of their own body weight.
Scott Bautch,a back doctor,said children under Grade 4 should stay with 10%.But it is also important that older children don't stay with over 15%,because their bodies are still growing.“Children are losing their balance and falling down with their school bags,”he said.
Parents and teachers are starting to tell children to only take home library books they will be reading that night.Some teachers are using pieces of paper or thin workbooks for students to take home.
One of best answers is,as some children said,to have no homework at all!

參考譯文
你上學時背的書包是否太重了?我敢肯定許多像你這么大的孩子都會說“是的”。不僅是中國的學生存在這種問題,美國的學生也存在書包過重的問題。
醫(yī)生開始擔心,患有背部和頸部疾病的學生年齡越來越小是書包過重造成的。
“我很難背著書包上樓梯,因為太重了?!币晃?1歲的美國學生里克·哈蒙德說。
里克背的書包屬于那種常見的雙肩背包,但許多學生選擇的是有輪子的書包。
但即使有輪子,上樓梯和公共汽車對孩子來說依然困難。許多學生就是因為書包過重而傷了背部和頸部的。
多重才算過重呢?醫(yī)生說,學生背的書包重量不應該超過自身體重的10%到15%。
斯科特·鮑奇是研究背部疾病的,他說,4年級以下的孩子所背的書包重量應該不超過自身體重的10%;年齡大一些的孩子不應該超過自身體重的15%,這很重要,因為他們還在長身體?!皶^重,孩子們?nèi)菀资テ胶獠⑺さ?。”他說。
父母和老師開始告訴孩子,只把那些晚上要讀的從圖書館借來的書帶回家。有些老師開始讓學生只帶幾張紙或很薄的練習冊。
正如有些學生所說,最好的辦法之一是根本不布置家庭作業(yè)。
