Spoken Bile can emulsify fat into small oil
droplets so that fat can be digested
more efficiently.
Written Emulsification of fat by bile leads to
efficient digestion of fat.
Spoken Villi provide a large surface area to
absorb food rapidly.
Written The large surface area provided by the
villi results in rapid absorption of food.
Example 4
Foregrounding Nominalization
Foregrounding the cause
1.
Owing to the large surface area
provided by the villi, the rate of food
absorption is increased.
2.
Because of the large surface area
provided by the villi, the rate of food
absorption is increased.
Foregrounding the result
1.
The rapid absorption of food is a result
of the large surface area provided by
the villi.
2.
The rapid absorption of food can be
attributed to the large surface area
provided by the villi.
