各位大侠,请帮忙翻译下这几句话,多谢了,尤其最好一句!
Many people can't imagine life without their cell phone. But now the World Health Organization is suggesting there might be a link between cell phone use and cancer. And that's causing millions of cell phone users to consider dialing back on usage. 最后这句不知道什么意思 consider dialing back on usage?

答案

试着解释一下本段：Many people can't imagine life without their cell phone.But now the World Health Organization is suggesting there might be a link between cell phone use and cancer.And that's causing millions of cell phone users to consider dialing back on usage.
许多人难以想象没有手机的日子该怎么过.但如今世卫组织建议称使用手机和癌症直接可以存有某种联系.这就让数百万的手机用户考虑起使用回拨来通话了.
dial back就是“回拨回去”,即不接听电话,然后回拨给对方,但是这里应该是使用座机回拨.
on usage（使用/应用）
