Welcome to the Unit 10 Review of Horizons B2. In this final block you will revisit the three big areas of the unit: the present perfect continuous, the past-habit forms used to and would, and the small toolkit of phrases that speakers use to repair communication when something goes wrong. The aim is not to learn new material but to bring the language together so that it feels automatic in real conversation and in writing.
The present perfect continuous
The present perfect continuous describes an action that started in the past and is still going on, or has only just stopped with visible results. The form is have/has + been + verb-ing, and we use it to emphasise the duration or continuity of an activity rather than the moment it is finished.

Question |
| I have been working all day. |
I haven't been sleeping well. |
Have you been waiting long? |
| She has been studying since 5 a.m. |
He hasn't been feeling well. |
How long have you been learning English? |
Common time expressions are for, since, all morning, all day, recently, lately. Be careful with stative verbs such as know, believe, want, like, own: we keep the simple present perfect for these, not the continuous. Compare I have known him for years (a state) with I have been working with him for years (an activity that continues). Forgetting this contrast is one of the most common B2 mistakes, so the review exercises below give you a chance to check it.
used to and would
Both used to and would describe past habits and routines that are no longer true. They are essential for storytelling and for talking about how your life has changed.
- used to + infinitive covers past habits and past states: I used to live in Cairo. I used to be very shy.
- would + bare infinitive covers only repeated actions, never states: When I was a child, I would read comics every night. (NOT: I would be shy.)
So if the subject is a state (a feeling, a place, a possession), use used to. If it is a repeated activity, both forms are possible, but would sounds more vivid and is especially common in narrative writing, while used to is the safer everyday choice.
Repair language
In real conversation, misunderstandings are normal, and skilled speakers use a small toolkit of phrases to keep communication flowing. The unit grouped these into repair language, and they fall into three families:
- Asking for repetition or clarification — Sorry? Could you say that again? I'm sorry, I didn't catch that. Could you speak a bit more slowly, please?
- Reformulating what you mean — What I mean is … In other words … Or rather … What I'm trying to say is …
- Correcting yourself or someone else politely — Actually, … No, wait — … Sorry, I think I gave you the wrong number. Let me rephrase that.
Notice that several of these contain the small communication verbs catch, repeat, rephrase, clarify, mean. Recognising them helps you understand the phrases even when speakers use them quickly.
Writing task: a short article about change
In the writing steps that follow you will write a short article of around 120–160 words titled "A habit I have left behind". The writing-strategy box below reminds you to mix tenses for effect.
Using contrast — Place used to / would and the present perfect continuous in the same paragraph. Linkers such as however, now, these days, since then will make the shift between then and now clear for the reader.
