【小题1】Look ! Stephen is lying(lie) on the bunk bed.【小题2】Lily, look(look) out of the window.

【小题1】Look ! Stephen is lying (lie) on the bunk bed.
【小题2】Lily, look (look) out of the window. There is a lovely dog.
【小题3】Everyone in our family likes (like) to watch Lucky 52.
【小题4】It’s importantnot to play (not play) with fire.
【小题5】They live a comfortable life and have nothingto worry (worry) about.

解析：【小题1】本句表示现在进行时，故用be+动词现在分词，躺的现在分词为lying，故本句空格处填is lying。【小题2】本题为祈使句，使用动词原形开头，故本句空格处填look。【小题3】本题的含义为在我们家里每个人都喜欢看幸运52，主语为单数第三人称，故本句空格处填likes。【小题4】本题的含义为不玩火是重要的，真正主语位于句尾使用动词不定式，否定形式为not to do，故本句空格处填not to play。【小题5】动词修饰不定代替nothing放在后，使用动词不定式to worry。

这个答案应该是对的
