Show Answer Key & Explanations Step-by-step solution for: Identify subjects and predicates worksheets | Worsheets library
To solve this worksheet, we need to break down each sentence into two parts: the Subject and the Predicate.

Here is the rule we will follow for every sentence:
* The Subject is the "who" or "what" the sentence is about. It usually comes at the beginning.
* The Predicate tells us what the subject is doing or what is happening to them. It usually starts with the verb (the action word).

Let's go through each sentence one by one:

1. My little brother poured water on my head.
* Who is the sentence about? "My little brother". That is the subject.
* What did he do? "poured water on my head". That is the predicate.

2. The tiny fern will take us to Antarctica.
* Who/what is the sentence about? "The tiny fern". That is the subject.
* What will it do? "will take us to Antarctica". That is the predicate.

3. I think I could eat one million grapes.
* Who is the sentence about? "I". That is the subject.
* What is happening? "think I could eat one million grapes". That is the predicate.

4. The caterpillar is nervous to turn into a butterfly.
* Who/what is the sentence about? "The caterpillar". That is the subject.
* What is the state/action? "is nervous to turn into a butterfly". That is the predicate.

5. The poor man got attacked by a cloud of mosquitoes!
* Who is the sentence about? "The poor man". That is the subject.
* What happened? "got attacked by a cloud of mosquitoes!". That is the predicate.

6. The brave squirrel ran into the bear's den.
* Who is the sentence about? "The brave squirrel". That is the subject.
* What did he do? "ran into the bear's den". That is the predicate.

7. Our science experiment caused a lot of smoke!
* What is the sentence about? "Our science experiment". That is the subject.
* What did it do? "caused a lot of smoke!". That is the predicate.

8. The donkey always thought he was a horse.
* Who is the sentence about? "The donkey". That is the subject.
* What did he do? "always thought he was a horse". That is the predicate.

Final Answer:
1. Subject: My little brother | Predicate: poured water on my head.
2. Subject: The tiny fern | Predicate: will take us to Antarctica.
3. Subject: I | Predicate: think I could eat one million grapes.
4. Subject: The caterpillar | Predicate: is nervous to turn into a butterfly.
5. Subject: The poor man | Predicate: got attacked by a cloud of mosquitoes!
6. Subject: The brave squirrel | Predicate: ran into the bear's den.
7. Subject: Our science experiment | Predicate: caused a lot of smoke!
8. Subject: The donkey | Predicate: always thought he was a horse.
