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. Why does the author say arch bridges can cross wider gaps?
2.Read the text, then answer the questions.
What Roots Do
Roots grow down while the stem grows up. They do two jobs.
First, roots hold the plant in the ground. A tall tree in a storm stays up because its roots spread wide under the soil.
Second, roots drink. Tiny hairs on the roots take in water from the soil. The water travels up the stem to the leaves.
A plant with damaged roots wilts, even if it is watered.
1. The author says a plant with damaged roots wilts. What reason is given?
