Question

两个动名词做主语，表单数还是复数

Answer 1

1 表单数：
Turning off the alarm clock and getting up quickly is the first thing he does before he goes out to work.
------这里，turning off the alarm clock and getting up quickly 被认为是一个统一的整体，缺一不可，是哟一是单数。
又如：Teaching and learning is going on well in our school.
------这里，teaching and learning被认为是一个不可分割的整体，所以是单数。

2 表复数：
Teaching and learning are different things.
------这里，teaching and learning属于各自不同的性质，所以是复数。

Answer 2

表复数，楼上答案第一种不是动名词，是分词形式
