avoid是及物動(dòng)詞,后面可以直接接名詞,代詞,動(dòng)名詞或者是接that從句.沒有avoid sb.to do/doing結(jié)構(gòu).在這個(gè)題中是接的省略引導(dǎo)詞that的從句.
剛剛看到樓上說可以接happening,是不對(duì)的,如果要接的話,it要改為物主代詞its才對(duì).
once you have cured the water pollution,you will have to take steps to avoid it___again.這里填happens,而不是to happen,happenin
once you have cured the water pollution,you will have to take steps to avoid it___again.這里填happens,而不是to happen,happening對(duì)嗎?
