Fill in the blanks.
1One day we ............... colonize Mars.
Wrong!
Use "will be able to" to talk about future ability; "can" has no future form, so "will can" is impossible.
2She has no interest ............... politics.
Wrong!
The noun "interest" is followed by "in".
3I was happy ............... my old friends again.
Wrong!
After "happy", we use the to-infinitive "to see" to give the reason.
4Parents must discourage children ............... unhealthy habits.
Wrong!
After "discourage", use "from developing" before the noun phrase.
5She is your neighbor, ...............?
Wrong!
An affirmative sentence with "is" takes the negative tag "isn't she".
6It was ............... that we did not go out.
Wrong!
The correct pattern is "so cold a day" before a that-clause.
7We were prevented ............... the class.
Wrong!
The passive verb phrase "were prevented" is followed by "from entering".
8It is time you ............... home.
Wrong!
After "It is time", use the past form "went" with present meaning.
9The driver was ............... injured in the accident.
Wrong!
The adverb "fatally" correctly modifies "injured".
10I recommend ............... go on a diet.
Wrong!
After "recommend", the correct clause form here is "that you".
11They made me ............... the whole story.
Wrong!
After "make" plus object, use the bare infinitive "repeat".
12If I knew his real motive, I ............... do this.
Wrong!
In the second conditional, the main clause uses "would not" before the base verb.
