"The Passive is used when it is not known or not important to know exactly who perfroms an action."
As opposed to...
The Active, which is used when the speaker knows who performed the action.
Form of the passive:
BE + PAST PARTICIPLE
Students read and
discuss the following article about a European mummy, Oetzi, found in the 1990s in the
thawing ice of the Alps.
The article uses a
lot of passive voice, primarily in the simple past and present perfect,
although there are a few modal passives as well.
This article has been abridged
from a much longer one, and the web link to the original is included below. (I took this exercise from the website associated with the grammar book I use.
Oetzi
the Iceman
Oetzi the Iceman is the modern nickname of a
well-preserved natural mummy of a man from about 3300 BC. The mummy was found
in 1991 in a glacier of the Otztal Alps, near the border between Austria and Italy. Oetzi
was named after the valley of his discovery. He rivals the Egyptian
"Ginger" as the oldest known human mummy, and he has offered a unique
view of the habits of Copper Age Europeans.
Oetzi was found by two German tourists on September 19, 1991. The
body was at first thought to be a modern corpse, like several others which had
recently been found in the area. It was roughly recovered by the Austrian
authorities and taken to Innsbruck,
where its true age was finally discovered. It is now being displayed at the
South Tyrol Museum of Archaeology in Bozen-Bolzano,
Italy.
The body has been extensively examined,
measured, x-rayed, and dated. Tissues and stomach contents were examined
microscopically. Scientists believe that at the time of his death, Oetzi was a
30-to-45-year old man, approximately 160 cm (5'3") tall.
Analysis of pollen and dust grains on his
clothing, and analysis of Oetzi’s teeth enamel show that his childhood was
spent near the present village
of Feldthurns, north of Bolzano. He later went to
live in valleys about 50 km further north.
The Iceman had 57 tattoos. Some were located on
or near acupuncture points that are used today to treat symptoms of digestive
problems and osteoarthritis. Interestingly, scientists have found that Oetzi
suffered from digestive problems and osteoarthritis. Some scientists believe
that these tattoos indicate an early type of acupuncture.
Oetzi’s clothes include a cloak, vest, and shoes.
They were quite sophisticated. The cloak was woven from grass, and the vest was
made of leather.
The shoes were waterproof and wide. They seemed
to be designed for walking across the snow; they were constructed of bearskin,
deer hide, and tree bark. Soft grass was wrapped around the foot and also placed
in the shoe. The grass functioned like warm socks. Recently, the shoes were
reproduced by experts. They are of such excellent quality, that there are plans
for them to be made commercially.
Other items found with the Iceman include a
copper axe, flint knife, and a bow and quiver of arrows.
Additionally, Oetzi carried two species of mushrooms.
One of these mushrooms is known to have antibacterial properties, and was
likely used for medical purposes.
Researchers believe Oetzi may have been involved
in a fight. Injuries from the fight may have killed him. A DNA analysis
revealed traces of blood from four other people on his gear: one from his
knife, two from the same arrowhead, and a fourth from his coat.
A CAT
scan revealed that an arrowhead was stuck in Oetzi’s shoulder when he died. The
arrow shaft had been removed, but the arrowhead had been left inside his body. He
also had bruises and cuts on his hands, wrists, and chest.
From such evidence, and an examination of his weapons,
molecular biologist Thomas Loy from the University of Queensland
believes that Oetzi and his companions were hunters who fought with a rival
group. At some point, he may have carried (or been carried by) a companion. He
may have been weakened by blood loss. As a result, Oetzi apparently put down
his equipment neatly against a rock, lay down, and died.
His body was covered by thousands of years of
ice and snow until his recent discovery. Pieces of his clothing, his hair, his
skin, and his personal possessions were well-preserved because of the cold
temperatures.
1. Initial grammar discovery: Provide
comprehension questions that elicit a passive response.
2. Identifying the passive: Students read the
article searching for uses of the passive. Remind students to look for forms of
the Be verb, but remind them that not
every Be verb is part of the passive!
3.
Practice: Students discuss why the passive voice is used in various
sentences.
4.
More practice: Make a jigsaw by dividing the article into Part A and B.
One student has the complete Part A with missing information in Part B, and the
other student has the complete Part B with missing information in Part A.
Students must ask and answer each other’s questions to complete the
information.
5. Still
more practice: Students change the passive to active where logical.
6. Just
one more practice! After the article has been thoroughly read and discussed,
the instructor puts key words on the board and the students recreate passive
sentences about Oetzi without referring to the article.
Example:
find -- Oetzi was found in 1991.
Name -- Oetzi was named after a valley in the Alps.
