I do hope you won’t need to warn anyone about anything, but in case you do, here is the list of most commonly used phrases:
(F*) If you take my advice, you won’t + inf
(F) Let me warn you against + -ing
(SF) Whatever you do, don’t + inf
(SF) One thing I wouldn’t do is + inf
(I) Beware of + noun / -ing form of the verb (present participle)
(I) Don’t + inf
*F stands for “formal”, SF for “semi-formal” and I for “informal”
EXERCISE 1: Let’s take a look at the following examples and decide whether they are formal, semi-formal or informal:
- Don’t you ever buy things in that shop!
- If you take my advice, you won’t ask him for help.
- Wherever you decide to eat, don’t go to that restaurant!
- Beware of tigers!
- One thing I wouldn’t do is drink more than two bottles of beer!
