Present / Past. Read the text. Fill in the blanks in the questions below.

People used to get water mostly from streams, lakes and rivers. Then cities started growing. This brought many people to one place. They needed more water for their homes and factories.
Sometimes it didn’t rain for a long time. Then the rivers had very little water left. People learned to save water for these dry times. They built places in which to store water. They called these places reservoirs.
Reservoirs hold water until people in cities need it. Large pipes carry water from reservoirs to the city. People also get water from wells.
Years ago, people lifted water out of wells in buckets. This was hard work and took a long time. Now they pump the water up. The pump makes it easier for people to get water where they want it.
