"Is there a God?"
"he could barely exist on such a low wage" "Can you live on $2000 a month in New York City?" "Many people in the world have to subsist on $1 a day"
误 The problem has been existed for weeks.
正 The problem has existed for weeks.
析exist是不及物动词,不可用于被动结构。
那样的事是从来没有过的。误 Nothing like that has ever existed in the world.
正 Nothing like that has ever existed.
析exist本身就有“存在于世上”的意思,因此,其后不用再接in the world。
