Remember, we use commas in a sentences to separate items in a list and instead of using 'and'. For example, I have a chocolate bar and a lollypop and a bag of sweets. Instead we say: I have a chocolate bar, a lollypop and a bag of sweets.
Here are some sentences that have too many 'ands' in. Change some of them for commas, but remember always leave the last 'and'.
