ADVERB CLAUSES OF TIME AND REASON

An adverb clause of time answers the question when; an adverb clause of reason answers the question why.

Think about when and why questions as you read the following sentences.

Many people feel depressed when it rains.
When it rains, many people feel depressed.
Many people are depressed because there has been so much rain.
Because there has been so much rain, many people feel depressed.

Punctuation Note: Reread the sentences above, paying close attention to the punctuation. When do we use a comma with a dependent clause? The dependent clause has to come first in the sentence; otherwise, do not use a comma. Another way to remember this is to make sure you never place a comma in front of words like because and when (subordinators). [DC, IC. or IC DC.]

TALKING ABOUT THE WEATHER: THERE vs. IT

When we talk about the weather, we use the filler subjects there and it. These subjects actually have no meaning, but they are followed by very different predicates. Study the examples below.

Filler ubject
Predicate (Rest of sentence)
It
is raining.
It
always rains this time of year.
There
is a lot of rain today.
There
has been a lot of thunder, too.
It
has been hot and humid, too.
There
is a cool breeze coming in.

You have probably noticed that it is followed by a verb. There is followed by a form of the verb be and a noun. The noun functions as the real subject of the sentence. [There is / There are + noun subject]

In the following sentences, note the use of a time clause attached to independent clauses with filler subjects there or it.

There will be rain when the dragonfly flies low.
When the dragonfly flies low, it will rain.
It will rain when the dragonfly flies low.
