Focus on … the suffi xes -ful and -less
You could do this box before or after students read the text. 
Get students to do the exercises. Ask students to suggest 
other words that end in -
ful
and -
less
. Examples include: 
harmful/harmless, hopeful/hopeless, meaningful/meaningless, 
powerful/powerless, useful/useless, childless, cloudless, 
dreadful, tearful
. Alternatively, write the root words, i.e. 
harm
, 
hope
, etc. on the board; students have to decide if you can add 
both suffi xes or only one of them (and which one).

next exercise. Alternatively, allow students to work at their own 
pace.

You could also ask students to scan the text and fi nd the 
word 
jargon
(
jargon-free
is in paragraph 8). Elicit the 
meaning of 
jargon
(special words and phrases which are 
used by particular groups of people, especially in their 
work) and 
jargon-free
(without jargon). Ask students what 
other nouns can be used with -
free
in this way. You could 
encourage them to fi nd out this information and to suggest 
collocations before the next lesson. (Examples include: 
alcohol-free [drink], dairy-free [produce], duty-free [goods], 
fat-free [milk], frost-free [winter], lead-free [petrol], nuclear-
free [zone], rent-free [accommodation], risk-free [venture], 
smoke-free [zone], tax-free [goods].)
 
You could also point 
out that 
carefree
is unhyphenated and means ‘having no 
problems or worries’.
