Well my question is which one is the correct, what happens or what happen,. Everything in life, even events that seem insignificant when they occur, happens/happen for a reason. Here is my sentence she wanted to show us something, then this happened/happens.
How the eye works Vision eye, Eyes, Visual
So, i got two question.
We use the future more when talking about a particular situation.
As it happens, as it happened 为惯用语，意为“碰巧、偶然”。用作补充性状语，说明主句描述的状态或事件是碰巧或偶然存在或发生的。对于这种惯用语，一般不需要再去扣语法，知道意思和. She told me the whole story exactly as it happended. As it happens, i went to university there ! Azzahsalem perhaps you could explain what it is you are not sure about in this sentence?
Should i use happen or happens in the following sentence: What happens when you drop a lighted match into a can of petrol? It is also essential for us to understand what you want it to mean, particularly as your. As it happens 和 it happens that…都可以表示“碰巧”，它们在意思上没什么区别，在用法上，as it happens 可用于句首或句末。如： as it happens, i have my notebook with me.
Which i guess means that in my case it happens every time.
Used to say that something happens after a period of time这里的happens 是因为表示习惯而使用了一般现在吗？类似在电影里听. And if i had said it happen to me every time, then that would mean that it. I used grammar checker but it doesn't tell me which one should i use. What happens if/when you mix oil and water?
句1中的it是否可以去掉？为什么？ 是否可以说： as happens, i went to university there !
