Dear All

I am in the process of completing the CELTA Pre-Interview task, but as I haven't studied grammar/language in detail for a long while I was really hoping if somebody would be really kind and help me a little. I have drafted my answers but would be grateful for any guidance or ideas.

The questions I am considering are as follows:
For each pair of sentences below. firstly state what the difference is, secondly state what method you would use in class to help students understand the difference. Think about different options like using visuals, giving examples, creating a context or scenario, mime, real objects, definitions etc.

1a) When I got there the party started.
b) When I got there the party had started
The difference in meaning is...

To help students understand the difference I would...

2a) to intervene
b) to interfere
The difference in meaning is...

To help students understand this difference I would...

I'd be really grateful for any ideas and would like to thank you in advance.

Very best,
Zara
