题目内容：

这个句子正确吗?There is no denying that to be a parent is by on means an easy thing.that .
that 后面可以加 to be 如果句子不正确

优质解答

以下两句都是对的：
1 There is no denying that to be a parent is by no means an easy thing -----to be 是动词不定式做主语
2 There is no denying that being a parent is by no means an easy thing.----doing是动名词作主语
注意,that在这里是连接词.
