Fill in the blanks with an appropriate verb form.
1What is copper ...............?
Wrong!
Use the passive question form with "used for" to ask about purpose.
2Paper ............... from wood.
Wrong!
The passive form "is made" shows that something is produced from a material.
3She left without saying goodbye. You seem ............... her.
Wrong!
After "seem," use the perfect infinitive "to have annoyed" for an earlier action.
4She left without saying goodbye. It seems that you ............... her.
Wrong!
After "It seems that," use the finite verb form "have annoyed" with the subject "you" for an earlier action.
5She seems ............... me.
Wrong!
The perfect infinitive "to have forgotten" shows that the forgetting happened before the present impression.
6It seems that she ............... me.
Wrong!
After "It seems that," the present perfect "has forgotten" fits the present evidence about a past action.
7She should have arrived an hour ago. She might ............... the bus.
Wrong!
After "might," use "have missed" to talk about a possible past event.
8She seems ............... the bus.
Wrong!
After "seems," the perfect infinitive "to have missed" expresses a likely past event.
9I had a mechanic ............... the bike.
Wrong!
In the causative structure "have someone do something", use the bare infinitive, so the correct form is "repair".
10When were antibiotics ...............?
Wrong!
After "were" in a passive question, use the past participle "discovered."
11The boat hit a rock and ............... rapidly.
Wrong!
The intransitive past simple verb "sank" describes what the boat did.
12Nobody ............... the crash.
Wrong!
With the singular subject "Nobody," the past simple form "survived" is correct here.
