After
reading the section How
Insects Eat Their Food, you came across a lot
of infinitives. What is the infinitive? To sneeze, to smash, to cry, to
jump, to run, to read, to eat, to slurp--all of these are infinitives.
What do you notice about all of these?
An
infinitive will almost always begin with to followed by the simple form
of the verb, like this:
TO
+ VERB = infinitive
Because
an infinitive is not a verb, you CANNOT add s, es, ed, or ing to the
end.
Examples: The
ants arrived to
grab the leftovers from the picnic. Insects
have wings to fly
all over the place to catch food. Bees
like to eat
nectar from flowers.
Practice: Complete each sentence by putting the words in
parentheses in the infinitive form.
Example: Derek wants Sarah (learn) Spanish. -->Derek
wants Sarah to
learn
Spanish.
1. It was too late for Tyler
(register) for classes.
2. The teacher told Tim (go) to the principal's
office.
3. Ryan's grandpa promised (buy) him a car for
graduation.
4. Ally went to the office (sign up) for softball.
5. Cristina didn't feel good but we persuaded her (come) to the party.
6. Dylan wanted Brady (help) him with his
homework.
7. I asked her not (call) me so late at
night because I go to bed
early.
Using
the infinitive, write a sentence about how the mouth of a fly,
butterfly, and ant allow them to eat their food. Refer back to the page
How Insects Eat
Their Food if you need to. There are plenty of examples in
the reading that you may use.
For example: The chewing and biting mouthpart of cockroaches allow
them to eat
a variety of foods.
