阅读下面的短文，选择正确答案。

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！

参考译文

你上学时背的书包是否太重了？我敢肯定许多像你这么大的孩子都会说“是的”。不仅是中国的学生存在这种问题，美国的学生也存在书包过重的问题。

医生开始担心，患有背部和颈部疾病的学生年龄越来越小是书包过重造成的。

“我很难背着书包上楼梯，因为太重了。”一位11岁的美国学生里克·哈蒙德说。

里克背的书包属于那种常见的双肩背包，但许多学生选择的是有轮子的书包。

但即使有轮子，上楼梯和公共汽车对孩子来说依然困难。许多学生就是因为书包过重而伤了背部和颈部的。

多重才算过重呢？医生说，学生背的书包重量不应该超过自身体重的10％到15％。

斯科特·鲍奇是研究背部疾病的，他说，4年级以下的孩子所背的书包重量应该不超过自身体重的10％；年龄大一些的孩子不应该超过自身体重的15％，这很重要，因为他们还在长身体。“书包过重，孩子们容易失去平衡并摔倒。”他说。

父母和老师开始告诉孩子，只把那些晚上要读的从图书馆借来的书带回家。有些老师开始让学生只带几张纸或很薄的练习册。

正如有些学生所说，最好的办法之一是根本不布置家庭作业。
