新标准初中英语八年级(下):Unit2 Some animals

[00:01.58]Module 2 THE FUTURE
[00:04.69]Unit 2 Some animals will die.
[00:08.86]1 Listen and read. Then say.
[00:13.09]Greenhouse¹ Gases
[00:15.40]Greenhouse gases come from cars and factories.
[00:20.43]The gases keep the heat from the sun
[00:23.10]on the earth.
[00:24.90]The gases are like a blanket² around the earth.
[00:28.85]They let the heat of the sun come in,
[00:31.88]but they stop some of the heat from leaving.
[00:35.33]So, they increase the temperature of the earth.
[00:39.74]Scientist believe that by 2030,
[00:44.60]temperatures around the world will rise
[00:47.60]by about 1.8 C.
[00:51.31]In hot countries in Africa and India,
[00:55.53]life will become very difficult,
[00:58.33]because the temperatures will be very high.
[01:01.68]More snow and ice will melt³,
[01:04.93]and the sea levels⁴ will go up.
[01:08.16]So, there will be floods,
[01:10.40]and there will be less land for people
[01:12.53]and animals to live on and grow food.
[01:16.35]Some food that people or animals need,
[01:20.13]will not grow in the higher temperatures, too.
[01:23.62]There will be no water in some areas.
[01:27.89]So, some animals will die and people
[01:30.68]will get sick.
[01:32.89]The higher temperatures could also cause fires
[01:36.26]and strong winds.
[01:38.67]We must stop greenhouse gases now!
