The number of children experiencing the early onset of puberty has doubled over the past 10 years, according to a survey analyzing children's endocrine diseases by the Women and Children's Hospital of Guangdong Province.
报道中说,据广东省妇幼医院一项有关儿童内分泌疾病的调查显示,早熟儿童的数量在过去十年中翻了一番。
这里的“early onset of puberty”指的就是早熟,即过早进入青春期。“Onset”是“开端,发生”的意思,我们还可以说“the onset of disease”(疾病的发作)、“the onset of old age”(老年的开始)和“the onset of winter”(冬天的来临)等。
