课文结构用法分析
In the 1960s and 1970s,the greatest fear was that the human race, and possibly all advanced life forms on the planet, could be wiped out by nuclear missiles, just at the push of a button .Today, however, environmental problems have taken over as the greatest risk to life on Earth. Scientists are thinking of ways to lower this risk, such as replacing coal and oil with forms of renewable energy. But they are also preparing for the worst what can we do if the terrifying scenes in films such as The Day After Tomorrow happen in real life What is our Plan B for Earth

Paragraph 1
wipe out意为“彻底摧毁”
Analyze the key points of the text
One option is to explore other planets to see if we could live on them. The most likely choice is Mars, which is relatively close to Earth and has an environment less hostile than that of other planets. Mars has fascinated people since ancient times, and today our interest in Martain exploration is greater than ever before. Films such as The Martian enjoy worldwide popularity. More governments and organisations are making efforts to educate the public on the Red Planet, for example, the Mars Desert Research Station in the Utah desert of the US and the Mars Village in North-west China’s Qinghai Province.

Paragraph 2
adj.可能的
Since the 1960s, we have been sending unmanned spacecraft to Mars. Our probes have orbited the planet, sending back valuable data and stunning images. Our robots have explored the Martian surface, testing the soil and searching for resources, water and signs of life. Encouraged by discoveries over the years, space agencies of various countries are planning manned missions to Mars that could take place within the next 25 years.

Paragraph 3
There is no doubt that humankind is drawn towards Mars, with dreams of making it our second home. However, sending people there will require all the skill, courage and intelligence of the human race. While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation. And even if the first settlers do reach Mars safely, they may not be able to return to Earth-ever. Staying alive will be a daily challenge, but as proved by the Biosphere 2 experiment, not impossible.

Paragraph 4
As early as the 1980s, scientists were building Biosphere 2 in the Arizona desert. It consisted of a closed space in which people, animals and plants could live together. The closed" concept meant that the space was designed to function with its own oxygen, food and water, needing nothing from the outside world. Although the two-year experiment was not a success, it did provide us with a better understanding of how humans might be able to live on another planet. More recently, scientists have succeeded in growing a variety of plants in an environment similar to that on Mars. That definitely is a big step forward.

For now, human settlement of Mars is still decades away. In the meantime, scientific research shows that the planet Earth is getting warmer. This change is being caused by human activity and is having a terrible effect on the biosphere. Until we are finally able to live on another planet, we need to take much better care of our own. Right now, it's the only one we have!
