The sun is our nearest star, and all of our energy comes from it. The sun sends out very large amounts of energy every day. We call this energy solar energy or radiant energy. With out the sun, life on earth would not exist because our planet would be totally frozen. We use this solar energy in many different ways. The sunlight lets us see and warms us. Plants use the light from the sun to grow. They store it as chemical energy. The energy is stored in their roots, fruits, and leaves. This energy feeds every living thing on the earth. When humans and animals eat plants, and the food made from plants, we store the energy in our bodies, in our muscles and in our brain cells.
1. Which does all of our energy come from?
A. the sun B. the wind C. the water D. nuclear power
2. If we didn’t have the sun, what would happen?

Read the passage, then answer the questions below
Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from the Sun.
At present, most of our electricity comes from the use of coal and gas, oil or nuclear power. This power could be provided by the Sun. One percent of the solar energy that reaches the Earth is enough to provide power for the total population.
Many countries are already using solar energy. Solar panels are placed on the roofs of a house and the Sun's energy is used to heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy, too.
Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar power instead of gas by the year 2015.
How long can the solar energy be stored?
It/ The solar energy can be stored for a number of days.
