4 a) Read the theory. Find four irregular Past Simple forms in the email.

The four irregular Past Simple forms found in the email are: saw, went, had, face (in the context of 'ready to face', though 'face' itself is not an irregular past simple form, the sentence structure implies a past action contextually, but 'saw', 'went', 'had' are clear irregular past simple forms from the email text. Re-examining the text, 'face' is not an irregular past simple form. The sentence is 'Harry Potter getting ready to face Voldemort'. The irregular past simple forms in the email are: saw, went, had. There are only three clear irregular past simple forms in the email. The theory box provides 'ate' as an example. Let's re-read the email carefully for any other irregular past simple forms. The email states: "I went to the cinema on Saturday night with my friends. We saw Harry Potter and the Half-Blood Prince... I found the film exciting..." 'Found' is also an irregular past simple form. So the four irregular past simple forms are: went, saw, found, had.
