Mixed Grammar: Be Able To, Question Tags, Interested In Doing Exercise

February 26, 2015 A2pdf

This exercise tests your understanding of basic grammar rules.

Progress 0 of 10 answered
1One day people will ............... colonize Mars.
Wrong!
After "will", use the base form "be able to" to talk about future ability.
2What have you ............... to find out?
Wrong!
The present perfect form is "been able" after "have".
3I am very much interested in ............... to paint.
Wrong!
After "interested in", use the gerund "learning".
4You don’t look happy ............... me.
Wrong!
After "happy", use the infinitive "to see" to give the reason.
5That dress is new, ...............?
Wrong!
A positive statement usually takes a negative question tag, so the correct tag is "isn't it".
6It was ............... that I didn’t go out.
Wrong!
With "so" before an adjective and a singular countable noun, the correct order is "so warm a day".
7They were ............... in love with each other, so everybody was surprised when they decided to part ways.
Wrong!
The adverb "madly" modifies the expression "in love".
8She was ............... injured in the crash.
Wrong!
The adverb "fatally" modifies the adjective "injured".
9Feel ............... to speak. I won’t tell anyone what you say.
Wrong!
The fixed expression is "Feel free" when giving permission or encouragement.
10I very much enjoy ...............
Wrong!
The verb "enjoy" is followed by the gerund "reading".
