Welcome to the Unit 9 Review. This unit looked at how to talk about the environment and the future in English. You learned two ways to talk about the future — will and going to — and a lot of new words for nature, environmental problems, and solutions. In this lesson, you will review all of that and finish with a short blog post writing task.
Let's start with the grammar. We use will for spontaneous decisions, predictions, offers, and promises. The form is will + bare infinitive: 'I'll help you with the bags' (offer), or 'I think it will rain tomorrow' (prediction). We use going to for plans we have already made, or when there is clear evidence now. The form is am/is/are + going to + bare infinitive: 'I'm going to study biology next year' (a plan), or 'Look at those clouds — it's going to rain soon' (evidence).
Here is a quick comparison:
| Use |
Form |
Example |
| Spontaneous decision |
will + infinitive |
'I'll have the soup, please.' |
| Prediction |
will + infinitive |
'She'll be famous one day.' |
| Offer / promise |
will + infinitive |
'I won't tell anyone, I promise.' |
| Plan / intention |
going to + infinitive |
'We're going to travel in July.' |
| Evidence now |
going to + infinitive |
'Watch out! You're going to fall!' |
Will shortens to 'll (I'll, you'll, he'll, she'll, we'll, they'll), and will not becomes won't. With going to, we contract the verb be: I'm, you're, he's, she's, it's, we're, they're. In speaking, going to often sounds like gonna, but only in informal chat — never in writing.
Now the vocabulary. The unit covered words for the natural world — forest, river, mountain, ocean, beach, lake, field, wildlife, habitat — for environmental problems — pollution, litter, waste, smoke, chemicals, climate change, global warming, deforestation, drought — and for solutions — recycle, reuse, reduce, save energy, plant, protect, clean up, turn off, throw away, cut down, use less. Useful adjectives include polluted, clean, green, sustainable, renewable, harmful, environmentally friendly.
The writing task is to write a blog post about how you help the environment. A blog post is a personal, short piece of writing with a title, an introduction, 2-3 short paragraphs, and a conclusion. Use going to for your plans, will for promises and predictions, and the environment vocabulary above. Using capital letters is a simple but important habit in English (UK): the first word of every sentence, the pronoun I (always), names of people and places, days and months, and the first word of a title. Always check your capital letters when you finish writing.
