    oil rigs have to be repaired frequently and divers,who often have to work in darkness a hundred feet under water,have been frightened out of their wits by giant fish bumping into them as they work.這里的bumping into為什么要用ing形式呢?而且have been frightened out of their wits這里為什么要用現(xiàn)在完成時(shí)態(tài)呢

    優(yōu)質(zhì)解答
    bumping into them as they work 做fish的ing形式的定語.
    divers ..have been frightened out of...潛水員們被那些巨型大魚嚇的六神無主.是過去發(fā)生的事情,且對(duì)現(xiàn)在的觀點(diǎn)陳述有影響,所以用 現(xiàn)在完成時(shí)態(tài).
