Welcome to the Unit 10 review! In this lesson, you will refresh three important areas from the unit: learning vocabulary (words about study and education), conditionals (sentences with if for different situations), and modals (helper verbs like can, should, must). By the end, you will feel more confident using these forms together when you speak and write.
Conditionals recap
Conditionals are sentences with two parts: an if-clause (the condition) and a main clause (the result). Each of the four types talks about a different kind of situation. Study the table carefully:
| Type |
If-clause |
Main clause |
Use |
| Zero |
If + present simple |
present simple |
facts / always true |
| First |
If + present simple |
will + base verb |
real / possible future |
| Second |
If + past simple |
would + base verb |
unreal / unlikely now or in the future |
| Third |
If + had + past participle |
would have + past participle |
unreal past (regret) |
Read the example sentences aloud. If you heat water to 100°C, it boils (zero — a fact). If it rains tomorrow, I will stay at home (first — a real possibility). If I had a year free, I would learn Spanish (second — an imagined situation). If she had revised, she would have passed the test (third — a regret about the past). Notice the verb tenses carefully. Mixing tenses in the wrong way is the most common mistake.
Modals recap
Modals are small helper verbs that come before another verb. They do not change form (no -s, -ing or -ed) and they are always followed by the base form. Here are the main modals and what they mean:
| Modal |
Meaning |
Example |
| can / can't |
ability / permission |
She can speak three languages. |
| could / couldn't |
past ability / polite request |
I couldn't understand the lecture. |
| should / shouldn't |
advice |
You should take more notes. |
| must / mustn't |
strong obligation / prohibition |
Students mustn't use phones in class. |
| may / might |
possibility |
It may rain this afternoon. |
| have to |
external obligation |
I have to wear a uniform. |
Modals are very useful together with conditionals. For example: If you join a study group, you should make faster progress (first conditional + modal of advice).
Learning vocabulary
The unit focused on words about learning and education. These collocations are common in spoken and written English: attend a class / a lecture / a seminar, revise for an exam (British English), take notes during a lesson, memorise facts or vocabulary, concentrate on your work, fail / pass an exam, graduate from university, get a degree in something, drop out of a course, and a subject (e.g. maths, history, biology). Pay attention to the prepositions: we say graduate from university, drop out of a course, and concentrate on your work. Using the right preposition makes your English sound much more natural.
Writing strategy: Using conditionals and modals
For this unit's writing task, you will write a blog post about the best way to learn a language. To make your writing more interesting, combine conditionals with modals to give advice. Use the zero conditional to give general rules: If you read every day, you learn new words. Use the first conditional with a modal to give future advice: If you join a language club, you will speak more fluently. Use modals like should, must or can to make your tips strong and clear: You should speak English every day. Try to include at least two or three conditional sentences with modals in your blog post. This will show what you have learned and make your writing more expressive.
