While vs During
While 和 During二者得区别
Hi! This is Kee from BBC Learning English, and today, I'm going to tell you the differences between while and during.
We can use while and during to say that a shorter event happened within a longer event. They mean the same, but the grammar's different.
After while, we have a clause. A clause is a group of words containing a subject and a verb. So we can say: While I was having lunch, my phone rang. Remember that the verb in the while clause is usually in an ING form.
We can also use while with just an ING form. So we can say: While having lunch, my phone rang. So we remove the subject and the 'be' verb.
However, during is different because it can only be used with a noun phrase. So we can say: During lunch, my phone rang. We cannot use a clause or just the ING form.
So, same meaning, but different grammar!
