Why Tall Buildings Do Not Fall Over

A tall building needs a wide, deep base. The base is called a foundation. It spreads the weight into the ground. Wind pushes hard on a tall building. Inside, a strong core of concrete runs from the bottom to the top like a spine. The core stops the building bending too far. The tallest buildings sway a little in strong wind. That is meant to happen. A building that could not bend at all would crack.

  1. 1. How is the foundation connected to the ground?
  2. 2. How is this text organised?
  3. 3. Which does the text explain first, the foundation or the core?
2.Read the text, then answer the questions.

How a Bridge Stands Up

A bridge has to hold its own weight and the weight of everything crossing it. The simplest bridge is a beam: a flat piece laid across a gap. A beam bridge cannot be very long, or it sags in the middle. An arch bridge is curved. The curve pushes the weight out to the ends, where the ground is solid. That is why arch bridges can cross wider gaps.

  1. 1. Which bridge does the text describe first?
  2. 2. How is this text organised?
  3. 3. How is the curve of an arch connected to the width it can cross?

  2. 2.1. The beam bridge. 2. It starts with what every bridge must do, then compares two kinds. 3. The curve pushes weight out to the solid ground at the ends, so it can span a wider gap.
