你好，我想請(qǐng)教Almost as many boys reported dieting as girls and many of the children surveyed said they were already dissatisfied with their body shape.中as many boys reported dieting as girls是什么成分？還有這里的reported是后置定語(yǔ)還是什么呢？謝謝你！

Almost as many boys reported dieting as girls 這是并列分句之一。

Almost as many boys主語(yǔ) reported謂語(yǔ)動(dòng)詞 dieting賓語(yǔ) as girls 比較狀語(yǔ)從句。

reported為一般過(guò)去時(shí)作謂語(yǔ)。
