[2020·烟台市高考诊断测试]Every year, the brightest young scientists from around the globe come together to participate in the world's largest precollege science competition, the Intel International Science and Engineering Fair (ISEF). They demonstrate their knowledge of science and engineering to improve the way we work and live.
margaret thatcherOne of 2019's winners, Katie Lu, found a method for removing oil from water. This concept can also be applied to the removal of microplastics from our oceans as well.
Here is what Katie told reporters：
My experience at the Intel ISEF was amazing! I remember on judging day, walking the exhibit hall and looking at the people gathered outside waiting to get in. My teacher turned to me and said, “That's the future right there.” It was so amazing to spend time with all of the participants who are going to do amazing things in the future.
My scientific career has taught me not to fear failure and not to be afraid to ask for help. It's really easy to be overwhelmed (击败) and wonder if what you're doing is going to work out, but even if it doesn't work out, it's OK! Always look on the positive side ! A failure now doesn't mean you're a failure forever. Failure makes success feel earned when it comes. Also, asking for help is good when you're struggling. You learn how to do things a lot faster and more efficiently.
I'm shocked that some people are still skeptical about climate change. It is real, it is dang

Additionally, people aren't really worried about their personal impact on the earth in terms of littering, overusing plastic or wasting resources. If we don't curb harmful human activity before it's too late, it will be a problem that affects all humans, not just tho that contribute.

[2020·沈阳市教学质量监测三]While the human world is suffering from the novel coronavirus outbreak, our planet is actually showing certain signs of “recovery” from the damage caud by human activity. According to the BBC, new satellite images relead by the European Space Agency showed that levels of air pollutants and greenhou gas have “fallen sharply”
in major cities in Europe and the ever since the lockdown started.
高三数学补习班This is what happened after recent discoveries in Antarctica. An international team of 89 scientists found that the ice in Greenland and Antarctica melted six times faster in the 2010s than it was in the 1990s. And in February, Argentina's Marambio Ba in Antarctica recorded a record high temperature of 20.75 ℃ on the continent.
So what exactly will happen if the temperature keeps rising and the ice keeps melting? A third study might give you an idea. A team of scientists drilled a hole into the afloor in West Antarctica and extracted (提取) material from underground, in which they found traces of roots, spores and pollen—typical products of a rainforest—that dated back 90 million years. In other words, Antarctica was very likely a rainforest back when the dinosaurs walked on Earth. But given the fact that the South Pole has four months of darkness during winter—even millions of years ago—scientists believe that the rainforest could only exist if the greenhou gas concentrations were extremely high back then to keep the continent warm when there was little or no sunlight.
“We didn't know that this Cretaceous (白垩纪的) greenhou climate was that extreme，” Johann Klages of the Alfred Wegener Institute in Germany and a coauthor of the rearch told the Guardian. “It shows us what carbon dioxide is able to do.”
With ice or no ice, Antarctica will be—and has always been—fine with extreme changes. The human world, however, may not be.
Now, during the coronavirus lockdown, we've en the changes resulting from less huma
n activity. Hopefully, we'll hold on to tho changes—not for Antarctica or the planet, but for ourlves.
5．What does Paragraph 1 mainly tell us?
A．Our planet is returning to its original state due to the novel coronavirus outbreak.
ronB．The lockdown of major cities contributed to the decrea of greenhou gas.
C．The novel coronavirus has no effect on the human beings.
