Explanations:Phrasal verbs are an essential part of the English language, often used to convey specific meanings that are not immediately apparent from the individual words. In this question, the context is about a washing machine that is not working. The phrasal verb "broken down" is the correct choice because it specifically means that a machine or device has stopped working due to a malfunction or failure.
Let's break down the concept of phrasal verbs and their usage in this context:
1. **Phrasal Verbs**: A phrasal verb is a combination of a verb and a particle (preposition or adverb) that together have a specific meaning. The meaning of the phrasal verb is often different from the meanings of the individual words. For example, "break down" means to stop working, while "break" and "down" individually do not convey this meaning.
2. **Contextual Usage**: In the sentence "I haven't got any clean clothes because my washing machine has broken down," the phrasal verb "broken down" is used to describe the state of the washing machine. The washing machine is not functioning, and it has stopped working due to a malfunction. This is a common usage of "broken down" when referring to machines or devices that are no longer operational.
3. **Other Phrasal Verbs**: The other options provided in the question are also phrasal verbs, but they do not fit the context of a malfunctioning washing machine. "Turned down" means to reject or reduce, "taken down" means to remove or dismantle, and "settled down" means to calm down or become stable. None of these phrasal verbs convey the idea of a machine that has stopped working.
4. **Common Misconceptions**: Students often confuse phrasal verbs with similar-sounding phrases. For example, "turned down" might be mistaken for "broken down" because both involve a negative change in state. However, "turned down" specifically means to reject or reduce, not to stop working. Similarly, "taken down" means to remove or dismantle, and "settled down" means to calm down or become stable, neither of which are appropriate in the context of a malfunctioning washing machine.
5. **Mnemonic**: A helpful mnemonic to remember the correct usage of "broken down" is to think of a machine that is "BROKEN down," meaning it is not working. This can help students recall the specific meaning of the phrasal verb in the context of a malfunctioning device.
In summary, the correct answer is "broken down" because it accurately describes the state of a washing machine that has stopped working due to a malfunction. Understanding the specific meanings of phrasal verbs and their appropriate usage in context is crucial for mastering the English language.
