How Trees Help Cool Cities

Introduction

New research shows that trees make cities cooler. This is very important for the weather.

Main Body

Trees stop the sun from hitting the ground. They also put water into the air. This makes the city feel cooler. Without trees, cities would be much hotter. But trees work differently in different places. In dry places, trees are great. In wet places, too many trees can make the air feel heavy and hot. Cities need a good plan for where to plant trees. Rich cities have many trees. Poor cities have very few trees. This is not fair. Also, trees alone cannot stop the world from getting hotter. We must also stop pollution.

Conclusion

Trees help a lot, but we need more plans to stop global warming.

🧊 The "Opposites" Pattern

To reach A2, you need to describe how things change. This text uses simple opposite words to show a contrast:

  • Rich (lots of money) β†’\rightarrow Poor (little money)
  • Dry (no rain) β†’\rightarrow Wet (lots of rain)
  • Cooler (less heat) β†’\rightarrow Hotter (more heat)

πŸ’‘ Word Tip: The "-er" ending

When we compare two things, we add -er to the end of the word:

Cool β†’\rightarrow Cooler Hot β†’\rightarrow Hotter

Example: "The city is hotter without trees."


πŸ› οΈ Use it like this:

Instead of saying "This is not cold," you can say "This is warmer." Instead of saying "That is not small," you can say "That is bigger."
