这里怎么用 increasingly ？谢谢

Now the ambitious plans to put US astronauts on the moon by 2020 to establish bases for further space exploration to Mars are increasingly in doubt. are 后面加副词increasingly 为什么呢？而increasingly 修饰哪个词呢？

修饰这个in doubt呀。。in doubt想当于doubtful，而increasingly是个副词呀，来修饰形容词。。。就这么回事。。

increasingly是个副词,一般放在系动词之后,表语前面 相当于 more and more的意思 表示"越来越" 比如: China is increasingly prosperous and strong.中国日益繁荣富强.

increasingly放在in doubt后就一目了然了。 increasingly修饰in doubt 可以看成……are in doubt increasingly

increasingly 是修饰 in doubt的 你把 increasingly 放在 in doubt 后面去就可以理解了～ 简单说， people think the ambitious plan is doubtful, increasingly 就可以理解为修饰think这个动词了.

increasely是修饰in doubt的。 再者are 为系动词。 后面可以加名词，形容词和副词做表语。

a growing/increasing number of a mushrooming number of a surging number of increasingly +形容词=more and more +形容词 名词+in mounting numbers=more and more +名词
