Welcome to the Unit 3 Review. Over the last few lessons you have been working with three important areas of English: time vocabulary, the present continuous for future plans, and prepositions of time. This review brings all three areas together and gives you a chance to check what you can remember before you move on to the next unit. By the end of this review you should feel confident using these three areas in writing and speaking.
Let's start with time vocabulary. You can tell the time in English in several ways. You can use numbers, for example 'seven o'clock' or 'ten thirty'. You can also use the expressions 'half past' (30 minutes past the hour), 'quarter past' (15 minutes past) and 'quarter to' (15 minutes before the next hour). It is also useful to know the parts of the day: 'morning' (until about noon), 'afternoon' (until about six o'clock), 'evening' (until bedtime) and 'night' (when you sleep). You should also remember 'noon' (12:00 midday) and 'midnight' (24:00). For days and dates, we say 'today', 'tomorrow', 'yesterday', 'this week', 'next month' and 'last year'.
The present continuous is not only for actions happening now. We also use it for fixed arrangements in the future. The form is simple: subject + be + verb-ing. We use it when we have already made a plan, often with another person, a place and a time. For example: 'I'm meeting my sister at the airport at six o'clock.' 'We're flying to Paris on Friday.' 'She's having dinner with Tom tonight.' The time expression usually comes at the end, but it can also come at the beginning for emphasis: 'Tomorrow I'm starting my new job.' This tense is very common in spoken English and in informal writing such as messages and emails to friends.
Now let's look at prepositions of time. We use at with clock times and parts of the day: 'at seven o'clock', 'at half past nine', 'at noon', 'at night'. We use on with days and dates: 'on Monday', 'on 6 March', 'on my birthday', 'on the weekend'. We use in with longer periods: 'in the morning', 'in July', 'in 2025', 'in summer'. A quick way to remember this is: at = exact time, on = a day or date, in = a period of time.
Finally, you will write a short blog post (60-100 words) about your plans for next week. Use the present continuous to talk about fixed arrangements, and remember the correct prepositions of time. Use capital letters at the start of sentences and for days, months and the word 'I'. Check your work when you finish. Good luck!
