Adverb Time Clauses

Average: 3.5 (40 votes)

Today's lesson looks at as soon as, while and as. There are three activities for you to try.

As soon as

We use as soon as when the second action happens immediately after the first action.  As soon as is an example of an adverb clause, which is often called a time clause. 

"As soon as I saw her, I knew there was something wrong."w


When two things happen at the same time, we can use the word while, which mean 'during that time'.  We usually use while with the past continuous tense because the meaning of 'during that time' indicate an action in progress.

"I can't talk to anyone while I'm driving."


When two things happen at the same time we can also use words like as and just as. They are both commonly used adverb clauses with time.  When an adverb clause begins the sentence, use a comma to separate the two clauses.  When the adverb finishes the sentence, there is no need for a comma.

"He was shot in the back as he tried to escape."

"The phone rang just as we were leaving."
