英语ofwhat使用句型和语法Of what use is medicine technology that allows the prolongation of life artificially.这种句子的正常语法是怎么样的?还有（）adults,young children find.括号里为什么选unlike,而不选not like?
网友回答
medicine technology is of use that it allows the prolongation of life artificially.主要是be+of+n.表示be + adj .
unlike表示不像,not like前要用be动词的吧
======以下答案可供参考======
供参考答案1:
Medecine technology is of use that it allows... 变问句就成为： Of what use is medicine....?
like 意思为“像”时是介词，它的反义词为unlike, like 意思为“喜欢”时是动词，它的反义词为dislike.
供参考答案2:
1 这是特殊疑问句
陈述句 是 medicine technology is of great use that it allows the prolongation of life artificially.
对great提问
what use is medicine technology of ....?
把 of 提前 就是本句
Of what use is medicine technology。。。？
2unlike adults是介词短语 作状语 一般不用 not like adults介词短语的否定形式
