Answer 1

1、A like to do sth或like doing sth 故排除CD find 是一眼就能发现的，而find out是要经过调查研究思索后才能发现的
2、B A是被动语态，而歌手与唱歌是主动关系，D中的to是不定式符号，后应跟动词原形。题中要表达的意思是这位歌手被听到正在唱一首美妙的歌曲，所以应用进行时态，排除C，选B
3、D A、B的说法不对，故排除，decide to do sth 故排除C
4、reading 每天早上都能听到这个女孩读英语。听到的时候肯定是正在读，所以用进行时
5、to visit 解释one day是指将来的某一天，是还没有发生过的事情，所以用to visit
6、What it 、这个句型和What a beautiful gir she is.有些类似，但是girl是可数名词，而 weather是不可数名词，故把a 去掉。

仅属个人看法！！！

Answer 2

1 A like to do 喜欢做某事，find out 查找出
2 C be heard to sing 或是be heard singing
3 D decide to do 决定做某事，whom 是who的宾格形式。
4 ？
5 to visit (hope to do sth 希望做某事)
6 how it （how+adj/adv+主语+谓语+it is）

Answer 3

1.A 原因：固定短语like to do sth.喜欢做某事，find out发现
2.b 原因：固定短语hear sb. doing听见某人做某事
3.D 原因：固定短语decide to do sth.决定做某事，此句中decide后跟whom引导的宾语从句
4.reading 原因：由语境推测可得
5.to visit 原因：hope to do希望做某事
6.What;it 原因：What+（a/an)+名词+代词+动词
