Question

Fill in the blank with the most appropriate word
She likes science fiction films, and so _________.
a) am I
b) do I
c) I do
d) I have

Answer 1

Hint: When writing the pronoun at the end of the sentence, we have to see whether the person is the subject or the object of the sentence. If he is the object, the sentence ends with the pronoun and if he is the subject, the sentence does not end with the pronoun.

Complete answer:
The correct answer is option b. Since the “I” is the subject of the sentence, we end the sentence with the pronoun. “So do I” is a popular phrase used.
Option a is wrong because “am” refers to being something and not doing/liking something. She is 16 years old and so am I. So, I am 16 years old. But if I had to use “do I”, the sentence would be, She likes being 16 years old and so do I.
Option c is wrong because I do is used in the beginning of a sentence. It is used in the sense of showing the doing of a thing. Carrying out a task is doing something. I do my homework daily. I do my household chores every day.
Option d is incorrect because “have” is not the correct verb. I have been working for the past 5 hours. I have to reach the airport early in the morning.

Note:
For such questions, the best way is to fill in the blanks with the options one at a time and then see if the sentence is making sense. The subject-object rules are also very important. Please remember that the pronoun is never used before the verb if it is at the end of a sentence.
