Show Answer Key & Explanations Step-by-step solution for: Direct Objects Worksheet
To solve this worksheet, we need to find the direct object (DO), indirect object (IO), or object of the preposition (OP) in each sentence.

Here is a quick guide to help you identify them:
* Direct Object (DO): Answers "What?" or "Whom?" after the action verb. (Example: I kicked the *ball*. -> Kicked what? The ball.)
* Indirect Object (IO): Answers "To whom?", "For whom?", "To what?", or "For what?" the action is done. It usually comes before the direct object. (Example: She gave *him* a gift. -> Gave to whom? Him.)
* Object of the Preposition (OP): The noun that follows a preposition (words like *in, on, at, with, by, for, of, about*). (Example: The cat is *on* the *table*. -> OP is table.)

Let's go through each sentence step-by-step:

1. Sentence: The idea of human flight fascinated Leonardo da Vinci.
* Verb: fascinated
* Question: Fascinated whom?
* Answer: Leonardo da Vinci.
* Type: Direct Object (DO)

2. Sentence: Leonardo often purchased live birds and set them free after extensively studying their wing structure.
* Verb: purchased / studying
* Look at the second part: "...studying their wing structure."
* Preposition/Verb phrase: studying acts as a verbal here, but let's look closer. Actually, looking at standard grammar for these worksheets:
* "purchased" -> What? "live birds" (DO). But "birds" isn't underlined.
* Let's look at "set them free". "Them" is DO. Not underlined.
* Let's look at "studying their wing structure". "Structure" is the object of the gerund "studying". Often treated similarly to a direct object in these exercises, OR we look for a preposition.
* Wait, let's re-read carefully. "after extensively studying their wing structure." There is no preposition right before "structure". However, in many elementary grammar contexts, if there is no preposition, it might be asking for the Direct Object of the verbal "studying".
* Let's look at sentence 3 for comparison. "spat out... flights".
* Let's look at sentence 8. "for the most inventive paper airplane". "For" is a preposition. "Airplane" is OP.
* Let's look at sentence 1 again. "of human flight". "Of" is a preposition. "Flight" is OP. But "Leonardo da Vinci" is underlined. That is the DO of "fascinated".
* Back to #2. The underlined word is structure. The word before it is "wing" (adjective/noun adjunct). The word before that is "their". The word before that is "studying". Since "studying" is an -ing verb form acting as a noun (gerund) or part of a phrase, the thing being studied is the direct object of that action. So, structure is the DO of the verbal "studying".

3. Sentence: Jordan wrote a spat about flights birds, including ostriches and kiwis. (Note: The text says "spat about flights birds", which seems like a typo for "book about flightless birds" or similar, but let's stick to the grammar).
* Underlined word: flights (or likely "flightless" in the original source, but here it looks like "flights"). Let's assume the underlined word is flights (or whatever noun is after "about").
* Preposition: about
* Noun after preposition: flights
* Type: Object of the Preposition (OP)

4. Sentence: Kevin enjoys science fiction books about life on other planets.
* Underlined word: planets
* Preposition: on
* Noun after preposition: planets
* Type: Object of the Preposition (OP)

5. Sentence: Miss Duncan showed her students a movie about the history of space exploration.
* Underlined word: students
* Verb: showed
* Question: Showed whom?
* Answer: Her students.
* Check: Did she show the students (IO) a movie (DO)? Yes.
* Type: Indirect Object (IO)

6. Sentence: The astronaut, John Glenn, orbited Earth on February 20, 1962.
* Underlined word: Earth
* Verb: orbited
* Question: Orbited what?
* Answer: Earth.
* Type: Direct Object (DO)

7. Sentence: Logan built his little brother a model of a spaceship.
* Underlined word: brother
* Verb: built
* Question: Built for whom?
* Answer: His little brother.
* Check: He built a model (DO) for his brother (IO).
* Type: Indirect Object (IO)

8. Sentence: Rachel won a prize for the most inventive paper airplane.
* Underlined word: airplane
* Preposition: for
* Noun after preposition: airplane
* Type: Object of the Preposition (OP)

9. Sentence: I sent you some articles about the possibility of extraterrestrial life on Mars.
* Underlined word: you
* Verb: sent
* Question: Sent to whom?
* Answer: You.
* Check: Sent you (IO) some articles (DO).
* Type: Indirect Object (IO)

10. Sentence: A Greek myth tells the story of Icarus flying too close to the sun while wearing wings made of wax and feathers.
* Underlined word: wax
* Preposition: of
* Noun after preposition: wax
* Type: Object of the Preposition (OP)

2. DO
3. OP
4. OP
5. IO
6. DO
