【題目】根據(jù)短文內(nèi)容,從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。
We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. __【1】___. It causes the evaporation (蒸發(fā)) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms(生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth’s surface.__ 【2】__. Of the energy that reaches the lower atmosphere,30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, _【3】___, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. ___【4】__ in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. _【5】__. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.
A.It is either reflected or absorbed by the gases in the upper atmosphere.
B.approximately 0.023%
C.These gases act like the glass of a greenhouse
D.greenhouse gases allow heat energy to escape from the Earth's surface
E.The amount reflected depends on the surface.
F.The Sun is the major source of energy for our planet
