These sentences describe a process: the process
of taking logs from the forest and making them into timber products.
They use the
passive in the simple present tense
.
We often use the passive when we are talking or writing about a
process
.
In the first sentence, we could say: "Workers take the logs
to the road and load them onto trucks." But we are more interested
in the logs than the people who do the work. So we put "the
logs" at the beginning of the sentence and then use the passive
.
In the second and third sentences the actions - what happens to
the timber (the transporting, the making) - are more important than
who does actions. Here we don't say who does the actions, because
it is not important.
We use the passive when the person or thing acted upon is more important
than who or what did the action. We also use the passive when we
don't know or don't care who did the action.
We can include the person or thing who did the action in a passive
sentence by using
by + a noun
.
For example:
|
|
We form the present simple passive with a form
of
be (is/are) + the past participle
.
|
|
In this sentence who wears the protective clothing
is important.
When we want to talk about the person or thing that does the action,
we don't use the passive, we use the active.

Changing active to passive voice

Highly
is
an adverb. We can use adverbs with verbs in the passive just as
we do with verbs in the active.
