关于一句话的英文分析
young children can be negatively affected by too much time spent on the computer every day.这句话我能明白意思,be negatively affected by 是一种习惯用法,后面一般加n.或v-ing,但这句话后面加了一个完整句子?那整个句子不就两个动词了?还是说这里的spent是名词,可以说不通啊

Answer 1

by后面不是一个完整的句子.
中心词是too much time, 后面"spent on the computer everyday"是后置定语解释time.
如果要改成句子的话就是by too much time that is spent on the computer everyday.
举例：the letters written at the back of the book.
