Have you ever seen a greenhouse? Most greenhouses look like a small glass house.

Greenhouses are used to grow plants，especially in nhouses work by trapping heat from the sun，the glass panels(板) of the greenhouse let light in，but keep heat from causes the greenhouse to heat up，much like the inside of the parked in sunlight，and keeps the plants warm enough to live in winter.

The earth's atmosphere(大气) is all around is the air that we nhouse gases in the atmosphere behave much like the glass panels in a ight enters the Earth's atmosphere，passing through the blanket of greenhouse it reaches the Earth's surface，land，water，and biosphere(生物圈)，they take up the sunlight's the heat is taken up，this energy is sent back into the of the energy passes back into space，but much of it remains trapped in the atmosphere by the greenhouse gases，causing our world to heat up.

The greenhouse effect is out the greenhouse effect，the Earth would not be warm enough for humans to if the greenhouse effect becomes stronger，it could make the earth warmer than a little extra warming may bring problems to humans，plants，and animals.

【回答】

are used for growing plants.*来自第二段的第一句。

2.根据短文第二段中温室效应的工作原理可知，*是 Because the glass panels of the greenhouse can let light in，and keep heat from escaping.

3.根据短文第三段的“much of it remains trapped in the atmosphere by the greenhouse gases”可知，温室塑料板的作用像空中大气层的作用，即*是 Greenhouse gases in the atmosphere.

4.根据最后一段内容可知，如果没有大气层的温室效应，人类就不能生存，即*为 Humans couldn't live because the earth would not be warm enough.

5.根据全文内容可知，主要是温室效应及对人类的影响，所以*为 It mainly tells us what the greenhouse effect is and its influence.
