Explanation

To answer the question "How should people wearing spectacles work with a microscope?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Function of a Microscope**:
- A microscope is an optical instrument that magnifies small objects, allowing us to see details that are not visible to the naked eye.

2. **Impact of Spectacles on Microscope Use**:
- People who wear spectacles typically do so to correct vision problems such as nearsightedness or farsightedness. However, when using a microscope, the magnification provided by the microscope can compensate for these vision issues.

3. **Evaluating the Options**:
- **Option 1**: Keep wearing spectacles. This is incorrect because the microscope's magnification can make it unnecessary to wear spectacles.
- **Option 2**: Never use the microscope. This is also incorrect, as people with spectacles can use microscopes effectively.
- **Option 3**: Take off their spectacles. This is correct because the microscope provides sufficient magnification, making spectacles unnecessary.
- **Option 4**: Either wear spectacles or take them off. This is incorrect because it is generally better to take them off for optimal viewing through the microscope.

4. **Conclusion**:
- The best practice for individuals wearing spectacles when using a microscope is to **take off their spectacles**. This allows them to take full advantage of the microscope's magnification capabilities.

### Final Answer:
People wearing spectacles should take off their spectacles when working with a microscope, as the microscope's magnification is sufficient for clear viewing.
