In which sentence is the subject understood?

Question

In which sentence is the subject understood?

A.
Your day skiing will be the best fun you'll ever have.

B.
Shake it well before pouring it into the glass.

C.
It is up to you how to decorate your room.

D.
Trying to simplify the clutter was a huge undertaking.

Answer 1

B.  It is implied that the second person is the subject.  Notice that the word "you" is never stated explicitly.

Answer 2

The answer is B: When the question asks about the understood subject, it means that there is not a subject explicitly stated in the sentence (as English grammar requires all sentences to have a subject). The subject of this sentence is the understood "you." This is called the imperative form and is used when giving instructions (Sit down.  Close the window. Wait for me here. . .etc.) This is the only time an English sentence (or clause) does not have a stated subject.

 

 

Answer 3

B is correct, not because we don't know what is being shaken but because no noun or preposition or phrase used as a subject is provided. "It" is the thing being shaken. "You" is the understood subject. Imperatives, commands like "shake it" or "do that", often have understood subjects. The subject "you" is understood; "You, shake it well." Hope this helps!

Answer 4

There is no "subject" in sentence B, given the verbal construction (Command form here).

In sentence C, the subject is the vague, but ubiquitous "it", i.e. the "understood" subject. It is understood to mean something such as "Your choice..."

Answer 5

B       It does not specify what is being shaken, but a reader would understand because of the context.
