Sentence Correction: Subject Verb Agreement Questions - Overview

The following question will help you practice identifying a Verb+ing/to+Verb subject, which is common in Subject Verb Agreement questions. The sentences in the question do not contain mistakes, so don't look for any.

Which of the following sentences contains a V-ing/to V subject?

Correct!

You correctly identified the form to search (for the mysteries of life) as the singular subject of this sentence. The conjugated verb seems, also in the singular, agrees with it in number.

Incorrect.

The singular subject of this sentence is The search. It is matched with the singular verb seems. The form to be (to Verb) is not the subject of the sentence, and has no matching verb. The words to be belong to the part of the sentence that tells us what the search seems like.

Remember, we are not looking for what is grammatically correct here; the question is which V-ing/To + Verb acts as the subject of the sentence?

Incorrect.

The subject of this sentence is it. Although the words to search have the form of to+V, they are not the subject of the sentence. Unending, while similar to the V-ing form, functions as an adjective describing the noun adventure.

Incorrect.

The main subject of this sentence is the search for the mysteries of life. It is matched by the verb is. Although the word unending has the form V-ing it is not the subject of the sentence, but rather is an adjective describing the noun adventure. The second verb seems has as its subject the pronoun it.

This question asks you to look for a word with either the form Verb+ing or to+Verb, which serves as the subject of the sentence.

Examples of these two forms are: watching, bathing, exercising, OR to watch, to bathe, to exercise.

It is not enough to identify the form, you also have to determine whether it acts as the grammatical subject of the sentence.

To search for the mysteries of life seems like an unending adventure.  
The search for the mysteries of life seems to be an unending adventure
Seemingly, it is an unending adventure to search for the mysteries of life.
The search for the mysteries of life, so it seems, is an unending adventure.
