Zadie Smith is a highly esteemed contemporary writer, known for her engaging essays and fiction. She often delves into global themes, tying different media forms together through comparative analysis. Just like Smith, you're encouraged to make connections across different texts in your oral presentations.

Smith doesn't just analyze one text in isolation. She draws comparisons between a film and a nonfiction text, indicating how they resonate on a global theme. This skill of comparative analysis allows for a broader and more profound understanding.

Real-World Example: Think about trying different flavors of ice cream. Tasting them separately gives you a sense of each flavor, but comparing them, their textures, and their ingredients can give you a more comprehensive understanding of ice cream making.

Smith's essay engages with an 'interesting global theme'. Such themes can be about social, cultural, political, or environmental issues that transcend national borders.

Real-World Example: Take climate change, for example. It's a global theme because it impacts everyone, regardless of their location or social status. Similarly, globalization is a theme since it connects economies and cultures worldwide.

Smith's essays are models for the kind of in-depth exploration that an oral presentation should aim to achieve. Like an essay, an oral presentation should be well-structured, analytical, and insightful. It should engage with the texts, their contexts, and their links to broader themes.

Real-World Example: Think of a TED Talk you've enjoyed. It's likely well-structured, insightful, and engaging, much like a good essay or oral presentation.
