1. the/friend/met/cinema/his/Dima/at.

This appears to be a fill-in-the-blank exercise where you need to choose the correct word from the given options to complete the sentence.

Let's break down each option:

• 1. the/friend/met/cinema/his/Dima/at.
• To form a coherent sentence, we need a subject, verb, and object, along with prepositions and articles. Considering the options, a possible sentence structure could be: "My friend met Dima at the cinema." or "His friend met Dima at the cinema." Without the full sentence structure or context, it's hard to definitively pick the best fit. However, if we assume a simple past tense sentence about meeting someone at a place, "at the cinema" is a common phrase.
• 2. last/didn't/Mila/me/week/write.
• This set of words suggests a past tense sentence. A likely sentence could be: "Mila didn't write to me last week."
• 3. Alex/morning/drink/the/milk/in/Did?
• The presence of "Did?" at the end strongly indicates a question. A possible question is: "Did Alex drink the milk in the morning?"
• 4. was/the/class/prettiest/our/girl/Sveta/in.
• This appears to be a sentence describing someone's appearance or evaluation. A possible sentence could be: "Sveta was the prettiest girl in our class."
• 5. the/year/pupil/in/Who/your/best/school/last/was?
• This is likely a question asking about the best student. A possible question is: "Who was the best pupil in your school last year?"
• 6. sister/Zoya/her/shier/is/than.
• This set of words seems to be for a comparative sentence. A possible sentence could be: "Zoya is her sister's shier/than." (Note: "shier" is likely a misspelling of "shyer" or "shier" which is not a standard comparative adjective. If it's meant to be "shyer", then it would be "Zoya is shyer than her sister.")

Since this is a fill-in-the-blank exercise and the full sentences are not provided, I have reconstructed plausible sentences based on the given words. If you provide the complete sentences with blanks, I can give you more precise answers.
