Introduction
The same as in the graph (described above), e.g., ‘The report
describes the….’
Description
Passive Voice
We use passive voice (to be + p.p.) with present simple
(am/is/are + p.p.), e.g., Cows are milked twice a day by the farmers.// e.g.,
Milk from cows is stored in refrigerators.
We DO NOT use passive voice for something natural, e.g., We do NOT
say, ‘Trash is biodegraded’ or ‘Water is evaporated’ or ‘leaves are
turned yellow in Autumn.’ We say, instead, ‘trash biodegrades,’
‘water evaporates,’ ‘leaves turn yellow in Fall/ Autumn.’

a milk machine.’
Process & Procedure example
Example (1): How paper is made
Paper is made of wood
Many of the world’s paper mills (1) are found in countries that have great forests, such as Canada and
the Scandinavian countries
The trees are felled (2)
The branches and leaves are
removed
The trees are transported to the sawmill
The bark is stripped from the trunks
The trunks are sawn into logs (log = a part of the
trunk or a large branch of a tree that has fallen or been cut off)
They are conveyed to the paper mill
They are placed in the shredder
(= a machine or other device for shredding
something, including documents)
They are cut into small chips
They are mixed with water and acid (pronounced ‘æs.ɪd’)
They are heated and crushed
to a heavy pulp
The wood pulp is
cleaned
Then it is chemically
bleached to whiten it
It is passed through rollers to flatten it
Sheets on wet paper are produced
The water is removed from the sheets
Then the sheets are pressed, dried, and
refined until the finished
paper is produced
(1) Mill = a building where grain is crushed into flour.// A factory where a particular substance is produced, e.g., cotton/ paper/ steel mill (*).
Example (2): How chocolate is made
Chocolate is made of the cacao
(1) tree.
When the cacao fruit is ripe
(2), it is harvested.
Then their seeds are removed.
Next, cocoa beans are
fermented in vats (3) for approximately/about a week.
After this, the beans are dried/placed on a trace in the sun to dry
Following this, the cocoa beans are
sent to/are transported
to (here we do not
use the term ‘transferred’) the chocolate factory
There/At the factory, the cocoa beans are turned into chocolate.
Notes:
(1) Cacao (pronounced kəˈkaʊ)
is the tree, while cocoa is the drink. However, it is often
used interchangeably for both the tree and the beverage.
(2) Ripe (pronounced raɪp)= (of fruit or grain) developed to the point of readiness for harvesting and eating.
(3) Vat = large container for mixing or storing liquid substances, especially in a factory (^^).
TIPS for writing the flow-chart (examples)
Example: the diagram shows how carbon dioxide (CO2)
pollutes the oceans. … Billions of tons of carbon dioxide are released into the air from fossil
fuels that are burnt/burned in factories, homes, and vehicles….. These gases eventually pass into the oceans, forming a weak acid (pronounced ‘æs.ɪd’). Scientists predict that the oceans' acid levels will rise considerably
between now and 2080. If this occurs and the
Earth’s seas become too acidic, much of the plankton (1) that lives there will be destroyed.
(1) plankton = the
small and microscopic organisms drifting or floating in the sea or freshwater
(one word), consisting chiefly of diatoms, protozoans, small crustaceans, and the
eggs and larval stages of larger animals. Many animals are adapted to feed on
plankton, especially by filtering the water)
Example: the diagram illustrates
the various stages in the production of plastic items. The raw materials must be initially transported from the
oil refinery to the plant. On arrival, they are poured into
a large drum. From there, they pass into a special oven, which heats the material at
high pressure so that long molecules of a plastic form (My comment: not ‘molecules are formed’ – it is a natural
procedure). The granules are then funneled
(1) into a rectangular molder
with a narrow end. The molder melts the plastic in
order to push it out into a mold. When
the plastic has hardened in the mold, the items can be
removed, and any waste material discarded. Before they can
be packaged (not ‘packed’), the finished products must
be checked for any
faults, so next, they are placed on a
belt and observed by a specialized employee. If they pass the inspection, they can be packaged into boxes and taken to the warehouse for storage.
(1) Funnel (pronounced ˈfʌn(ə)l) = guide or channel something through or as if through a funnel, i.e., a tube or pipe that is wide at the top and narrow at the bottom, used for guiding liquid or powder into a small opening.
Avoiding mistakes on the flow-chart (examples)
Example (1)
Vegetables and fruits
in the greenhouse (1 word) are gathered
and transported to the factory. There, they are laid (not
‘being laid’) on a conveyor belt system (better
than the ‘belt conveyor system’). They enter the
chain of preparation where initially they are sorted
(beware of the typo ‘shorted’) by hand so
that the undesirable vegetables are removed (not ‘to
be removed’). Following this, they are peeled or
polished according to their type. Next, when
is needed (not ‘it is needed’), they are sliced.
After this, they enter the stage of chilling.
Following this, they are placed in a spinning
machine so that they get dried (not ‘so that to get dried’).
Example (2)
Firstly, as can be inferred from the flowchart, the chain begins with the
three main ingredients, water, flour, and yeast, that are poured into
an (do not omit the article ‘an’ here) industrial mixer. Then
dough (1) is mixed, (then) fermented and after this, it
is transferred to a special divider.
There, with the power of a plunger, it enters a rotating cylinder
where it is divided into (not ‘divided in’) pre-specified
weights of (not ‘weights to’) equal proportions. Following this,
it is conveyed on a (do not omit the article ‘a’ here) belt
to the factory (not ‘manufactory’), where it is ready to be baked/
it is ready for use. (
1) Dough (ronounced dəʊ) = a thick, malleable mixture of flour and liquid, used for baking into bread or pastry
Example (3)
As can be seen from the flowchart, refinery oil is transferred by
truck (1), and the
raw (= unprocessed) material
is transported to the plant where it is poured
into (not ‘pour in’) a large vat (2). Next, it passes to a
high-pressure oven where it is heated – a procedure by
which it is (not ‘by with is’) converted into (not
‘converted to’) long molecules consisting of plastic granules. Following
this, plastic granules are funneled (3) into a moulder (or
‘molder’ in North American English), where plastic is melted
and (becomes) molten. After this, the molten product
is released and hardened. Then it is conveyed
on a belt and packaged (not packed).
(1) Beware of the typo ‘track’ – remember ‘music track’ and the phrase ‘follow the track to the farm’ to avoid the typo!
(2) Vat = a large tank or tub used to hold liquid, especially in the industry
(2) Funnel (pronounced ˈfʌn.(ə)l) = guide or channel something through or as if through a funnel, i.e., a tube or pipe that is wide at the top and narrow at the bottom, used for guiding liquid or powder into a small opening.

c) The Diagram (illustration) (IELTS exams)
(Rare, but it may be asked! It is easier than
the graph, which may explain its scarcity!)
It is actually a diagram without process. It consists of a diagram and often a table with figures
related to the diagram. The
key here is to compare. The TIPS have already been given above.
Example:
The diagram and table provide information
on different types of dredgers used to clean up water from mud. Canal and coastal dredgers perform a similar function, but they differ considerably
regarding their size and power. A canal
dredger boat carries a suction pump with rotating blades, which are lowered into the canal by two hydraulic arms. These stir up the slurry (1) on the bottom of the canal, which is sucked up by the
centrifugal (2) pump. From the pump, the mud is
discharged through a large tube
into a shuttle (3) boat behind the
dredging boat. When the shuttle boat is full of mud, it is towed away (4),
and the mud is dumped. Compared to a coastal dredger, a canal dredger is a lot smaller. It
is only 20 meters long, rather than 90 meters, and is also less broad, with
a hull breadth of 7 meters compared to the hull breadth of 14 meters of the coastal dredger. Coastal
dredgers are made to be used
in the sea and can suck up sand
and slurry from a depth of 40 meters, while canal dredgers are made for much shallower waters (1.9 meters). Clearly, dredgers must be designed to suit the environment in which they operate.
(1) Slurry (pronounced
slʌri) = a semi-liquid mixture, typically of fine particles of manure,
cement, or coal and water.
(2) Centrifugal ((pronounced ˌsen.trɪˈfjuː.ɡ(ə)l in British English or senˈtrɪf.jə.ɡ(ə)l in North American English) = (of a turning object) moving away from the point around which it is turning (**))
(2) shuttle = travel regularly between two or more places.
(4) Tow something away = (phrasal verb) To lift a
vehicle that has been parked illegally onto an official truck and take it to a
place from which you have to pay to collect it (^^)].
