1:
How
a Canal Lock Works
Talk
with a partner. What would you write for this task?
Cut
up strips and shuffle and have students re-arrange them in order in
groups
When
a boat needs to move to a lower water level, the upper gates are
opened to allow the boat to enter the lock.
|
When
the boat is in place, the upper gates are closed behind it and
paddles in the lower gate are opened to release water.
|
The
boat then drops as the water level falls.
|
When
the water level reaches the same level as the water in the next
section of the canal, the lower gates are opened and the boat
exits the lock.
|
When
a boat needs to enter a higher water level, the procedure is
reversed.

Lastly,
look through the sample writing, and underline all the verbs that are
in the passive voice. The first one is done for you.
Why
are these verbs written in the passive?
A
canal lock is a device, which is
used
to move boats up or downhill in a canal. It consists of gates, which
separate different water levels. The gates have pipes called
‘paddles’, which are used for lowering the water level in the
lock.
When
a boat needs to move to a lower water level, the upper gates are
opened to allow the boat to enter the lock. When the boat is in
place, the upper gates are closed behind it and paddles in the lower
gate are opened to release water. The boat then drops as the water
level falls. When the water level reaches the same level as the water
in the next section of the canal, the lower gates are opened and the
boat exits the lock. When a boat needs to enter a higher water level,
the procedure is reversed.
In
conclusion, a canal lock is a simple system, which enables boats to
move through a canal.
Answers
The passive voice is used here
because the canal lock and gates are being controlled by human
operators, and are not performing the actions. The human operators
are performing the actions, but since the gates and the canal locks
are the subject of the sentence, the verbs are written in the passive
voice.
A canal lock is a device, which
is used to move boats up or downhill in a canal. It
consists of gates, which separate different water levels. The gates have pipes called*
‘paddles’, which are used for lowering the water level in
the lock.
When a boat needs to move to
a lower water level, the upper gates are opened to allow
the boat to enter the lock. When the boat is in place, the upper gates are
closed behind it and paddles in the lower gate are opened
to release water. The boat then drops as the water level falls. When the water level
reaches the same level as the water in the next section of the canal, the lower
gates are opened and the boat exits the lock. When a boat
needs to enter a higher water level, the procedure is reversed.
In conclusion, a canal lock is a simple system,
which enables boats to move through a canal.
* called in the sentence “the gates have pipes called paddles”
is a reduced passive sentence used as a
modifying past-participle clause. The
full meaning is understood to be “the gates have pipes which are
called paddles.”
