Based on the text provided, I can see the instructions to complete the sentences after reading a letter. However, the letter itself is missing. To accurately complete the sentences, I need the content of the letter.
Here's how I would approach completing the sentences if I had the letter:
- Lucy and her family are... I would look for information in the letter about what Lucy and her family are doing at the present time. For example, they might be 'visiting their grandparents' or 'planning a trip'.
- They are going to see... I would scan the letter for information about someone or something they are planning to visit or meet. For example, 'They are going to see the new museum' or 'They are going to see their cousins'.
Since I don't have the letter, I can't give you the completed sentences. Please provide the letter so I can help you properly!
