Look at this text from some research done on improving performance in sports. Look at the verbs in bold

,

Then draw lines between the verb and the

Ever since the early years of the 20
th
century,
when the International Athletics Federation
began
keeping records, there
has been
a
steady improvement in how fast athletes
run
, how high they
jump
and how far they
are able
to throw huge objects of every
description, including themselves, through
space.
The times and distances for the power
events – those that, like the 100 metre
sprint and the long jump,
require
a relatively
brief, explosive release of energy –
have
improved
about 10 to 20 percent. In the
endurance events, the results
have been
even
more dramatic. At the 1908 Olympics in London,
John Hayes of the US team
ran
a marathon in the time
of 2:55:18. In 2008, Ethiopia’s Haile Gebrselassie
set
a new
world record of 2:03:59, almost 30 percent faster.
