The document provides examples and exercises on describing sequences of events using terms like preceding, simultaneous, and following. It covers sequences in natural processes like the water cycle, heating water, and a plant's lifecycle. Students are asked to order events, complete sentences describing events, and write multi-sentence descriptions of processes like how a refrigerator works. The purpose is to practice using language to accurately sequence and relate events in processes.

2. Section 1
PRECEDING, SIMULTANEOUS, and following
EVENTS
1. Look and read :

4. Each sentence contains two events, X
and Y. Read out the sentence which
means :
 X occurs at the same time as
( simultaneously with Y )
 X occurs at the approximately the
same time as, or soon after , Y.
 X precedes Y.
 X follows Y.
 Y is at the end of X.

5. Answer :
a)Before the sun appears over the horizon
occurs at the same time as the sky begins to
light
b)The light increases occurs at approximately
the same time as or soon after the sky begins
to light.
c)The sky begins to lighten precedes the light
increases.
d)The light increases follows the sky begins to
the sky.
e)The sun climbs up the sky is at the end of the
sky begins to lighten.

6. Now complete these sentences :
…… the sun rises, the air temperature rises.
……the sun reaches the highest point in the sky,
it begins to descend.
……the sun descend, the air temperature falls.
........the sun sets, it approaches the horizon.
.......the sun sets, the sky becomes completely
dark.
…...the sun sets, the day ends.
The night begins ….., the sun sets.
The night continues ……. The sun rises.

7. Answer
when the sun rises, the air temperature rises.
After the sun reaches the highest point in the
sky, it begins to descend.
if the sun descend, the air temperature falls.
At time the sun sets, it approaches the horizon.
When the sun sets, the sky becomes
completely dark.
When the sun sets, the day ends.
The night begins.when the sun sets.
The night continues until The sun rises.

8. 2. Number these events in the order in which they occur when water
is heated. Give simultaneous actions the same number
a) The water becomes hot
b) The gas is lit.
c) Bubbles appear

9. d) Steam appears
e) The gas is turned on
f) Bubbles burst
g) Bubbles rise to the surface

10. h) The water evaporate.
Now look at the two points in the example :
As soon as the gas is turned on, it is lit.
( X follows Y immediately )

12. Answer :
i) As the water evaporates, Bubbles rise to the
surface
j) As soon as the bubbles burst, The water
becomes hot
k) When the bubbles rise to the surface, Bubbles
burst
l) As soon as the gas is turned on, The gas is lit.
m) Before the gas is lit, The gas is turned on.
n) After the water becomes hot, The water
evaporate
o) As soon as the bubbles appear, Steam appears

13. 3. Number these events in the order in which they occur :
a) The water ceaces boiling.
b) The flame is extinguished.
c) The water starts to boil.
d) The water continues

14. f) The gas is turned off.
g) The bubbles is disappear
Now write complete sentences joining these pairs of
events and making any other necessary changes :
d + *b
*c + d
*b + a
*e + b
*a + e
*a + f
*use one of these expressions :
when
before
until
after As soon as

15. Example : as soon as the gas is turned off, the flame is
extinguished.
Answer :
1) The water continues, until the flame is extinguished.
2) after the water starts to boil, the water continues boiling.
3) As soon as the flame is extinguished, the water ceases
boiling
4) After the water starts to boil, the flame is extinguished.
5) Until the water ceases boiling, the gus is turned off.
6) When the water ceases boiling, the bubbles disappear.

The liquid passes through an expransion, until
the pressure is reduced and crossing heat is
taken in evaporation .

pump. As soon the gas is comperessed , until
liquefaction .
When the gas changes Into liquit, heat is given
out to the atmosphere.

32. SECTION 4 STAGES
10. Look again at the life-cycle of a plant and then read
this description :
First, the seed is sown.
Next, it is watered.
Then, the seed begins to swell.
At this stage ; germination begins.
Subsequently, the roots develop.
Meanwhile, the leaves also develop.

33. Later, flowers appear.
Then, pollination take places.
During this process, the stigma receives pollen.
Afterwards, the fruit froms.
Eventually, the plant dies.
Finally, the plant decomposes.

34.  The words in italics mark stages in a process.
Now give the following :

First, the seed is swon.
Finally, the plant decomposes.
Next, it is watered

At this stage, germination begins.
Subsequently, the roots develop.
Meanwhile, the leaves also develop.
Later, flower appear.
During this process, the stigma receives pollen.
After wards, the fruit froms
Eventually, the plant dies.

Afterwards,
the foundation are laid.
Then,
the house is ready to live in.
Later,
the roof is made.
Eventually,
the doors and windows are put in.
Finally,
the electricity and water systems are
installed.
