Part 1. Choose the correct item.

Let's go through each question one by one: 1. **This is Tom's room, ...?** * The correct answer is **a) isn't it**. This is a classic question tag. We use "isn't it" because the main statement is positive ("This is Tom's room"). 2. **I don't know if she ... me about it.** * The correct answer is **b) asks**. The sentence needs a present tense verb to match the tense of "I don't know". 3. **This text ... at the previous lesson.** * The correct answer is **c) was translated**. Since the text is being acted upon, we need the passive voice, and since it's referring to the past (previous lesson), we use "was translated". 4. **He's just built a tower, ...?** * The correct answer is **b) hasn't he**. This is another question tag. The main statement is "He's just built a tower", which is a shortened form of "He has just built a tower". Therefore, the correct tag is "hasn't he?". 5. **He'll ... find the book in the library.** * The correct answer is **b) can**. "He'll be able to" is grammatically correct but sounds too wordy. "He'll must" is grammatically incorrect. Therefore, the most natural and grammatically sound option is "He'll can find". However, that too is incorrect. The correct answer is "He'll be able to". It means that he will have the ability to find the book. 6. **Boys, you'll have to do everything ....** * The correct answer is **b) yourselves**. Since the subject is "Boys", the reflexive pronoun must be plural and refer to "you", hence "yourselves". 7. **If she ... me about it I shall tell her everything.** * The correct answer is **a) ask**. This sentence sets up a conditional. It should be: If she ask me about it, I shall tell her everything. 8. **Look at ... stars. They are beautiful, aren't they?** * The correct answer is **b) these**. The speaker is referring to specific stars that are visible, so "these" is the most appropriate. 9. **The bike belongs to ....** * The correct answer is **b) mine**. This refers to something belonging to the speaker, so "mine" is the correct choice. "My" needs to be followed by a noun (e.g., "my bike"), and "me" is an object pronoun. 10. **Tom is the best pupil. He ... the best pupil in his class.** * The correct answer is **b) has always been**. This means that for all the time he's been in the class, he's been the best. The other options don't really fit the context as well. **Summary in Russian:** 1. Правильный ответ: a) isn't it (разделительный вопрос, подтверждающий утверждение). 2.
