Conditionals, Phrasal Verbs and Sentence Transformation: Class 8 Study Guide
Conditionals describe possibilities and consequences. Phrasal verbs and transformations make speech and writing natural and varied.
A conditional sentence has an if clause (the condition) and a main clause (the result). The zero conditional states facts: If you heat ice, it melts. The first conditional is a real possibility: If it rains, we will stay home. The second conditional is unlikely or imaginary: If I won a lottery, I would travel. The third conditional is about the past: If she had studied, she would have passed.
A phrasal verb is a verb with a particle (an adverb or preposition) that gives a new meaning: give up (stop), look after (take care of), put off (postpone), run out of (have no more).
Four conditionals
| Type | If clause | Main clause | Use |
|---|---|---|---|
| Zero | present simple | present simple | facts |
| First | present simple | will + verb | real future possibility |
| Second | past simple | would + verb | imaginary or unlikely |
| Third | past perfect | would have + past participle | imaginary past |
Phrasal verbs
Many have more than one meaning: take off (remove a coat, or an aeroplane leaves the ground). Some can be separated (She turned the offer down / turned down the offer), others cannot (look after the baby). Learn them in sentences, not in lists.
| Phrasal verb | Meaning | Example |
|---|---|---|
| give up | stop trying | Never give up your dreams. |
| look into | investigate | The police will look into it. |
| carry on | continue | Carry on with your work. |
| call off | cancel | The match was called off. |
| come across | find by chance | I came across an old photo. |
Transforming sentences
