which 用法
North Korea announced Thursday that it will launch its newest rocket,which many outside the country suspect is a long-range missile that can hit the U.S.mainland,sometime from April 4 to 8,giving other countries three weeks to decide whether to shoot it down or deal with the trouble in another way.
中的
which many outside the country suspect is a long-range missile that can hit the U.S.mainland,
單看這個句子中的which many outside the country suspect 好像是作主語從句
而語法上沒有查到which加一個句子作主語的用法這里怎么解釋?
我就是想問{which many outside the country suspect is a long-range missile that can hit the U.S.mainland,} 這個定語從句再進一步劃分句子成分怎么劃？
