Part III.好句子背诵。
Step1：背诵清单。
There is little doubt that Earth is getting warmer and warmer.毫无疑问，地球正在变得越来越暖。
A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate.海洋和大气的变暖以及冰川融化和海平面上升提供了全球气候急剧变化的证据。
According to the scientists who found its dead body, all that remained of the polar bear was “skin and bones".据发现它尸体的科学家说，这只北极熊只剩下了“皮包骨”。
An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died.一位研究北极熊多年的专家说，从北极熊尸体的位置来看，这只熊似乎是饿死了。
Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food.专家称，气候变化导致的低海冰水平意味着熊不能像以前那样捕食海豹，所以它不得不走更远的距离去寻找食物。
Climate scientists often mention a key climate process called the “greenhouse effect", which has two common meanings: the "natural" greenhouse effect and the "man-made" greenhouse effect.
气候科学家经常提到一个关键的气候过程叫做“温室效应”，它有两个共同的含义:“自然的”温室效应和“人为的”温室效应。
Greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth's surface as short-wave radiation.温室效应是指太阳的热量进入大气层，以短波辐射的形式温暖地球表面。
When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth's surface temperature to rise quickly.
当人们燃烧化石燃料产生大量额外的温室气体时，更多的热能被困在大气中，导致地球表面温度迅速上升。
There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives.有有力而全面的证据表明，气温上升已经导致全球极端天气和自然灾害增加，不仅造成严重的破坏，而且还造成人命损失。
Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions.各国政府需要考虑制定政策并采取适当的行动和措施来减少温室气体排放。
We as individuals can also reduce our “carbon footprint" by restricting the amount of carbon dioxide our lifestyles produce.作为个人，我们也可以通过限制生活方式产生的二氧化碳量来减少我们的“碳足迹”。
It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet.
我们有责任抓住每一个机会，教育每个人关于全球变暖及其原因和影响，因为这是影响我们这个星球上所有人的最严重的问题。
