72. The brightly colored kingfisher that perches
until it sights a fish, then dives into the water
to catch its prey.
看了解释,把B中的THAT去掉,我还有问题,去掉了THAT,两个谓语动词用了THEN(副词)连接,这样可以吗?好象不妥啊,大家帮我解答一下,先谢谢了!

是三个谓语,如黑线所化,两个连词until和then,是对的,谓语数=连词数+1
"then" is a 连词???????????????
对不起,一时大意没说清楚
副词按功用分为句子副词(actually,decidedlly.....),连接副词(therefore,moreover,otherwise,then.....),解释副词(as,for example....),关系副词....
其中连接副词与等立连词(如and,or,but...)的性质相似,可以连接并列的单词,短语,从句或分句等.
