    As the school year barely starts in Denver, French teacher Melanie is filled with worry that her students are always absent-minded. Yet, the problem isn’t messaging, enjoying video games or delivering notes. Surprisingly, the problem is about the ongoing heat wave in Denver.

“Today was a little bit hot, so I noticed kids were very sleepy and they were having to get up to drink water quite often.” said Melanie, who works at Denver’s East High School. “If you lose too much water, and you have to keep going to the water fountain, that can take away from their classroom experience.” While nodding off in class on a warm day may seem acceptable for the average teen, Melanie’s observation carries a bigger consequence than dry lips.

“There have been quite a few media reports about teachers noticing that students weren’t able to focus on hotter days,” said R Jisung Park, a researcher, “Does a hotter climate during the school year actually affect the rate of learning?” The drops in academic achievement couldn’t be explained by hotter weekends or hotter summers, but the trend was connected to higher temperatures on school days alone.

The connection between lost learning and a greater number of hot days is one more example of how climate change is already affecting our lives — and it’s an alarm bell for what we stand to lose in the future. Humans still have time to lessen the worst consequences of continued global warming. Without the unlikely important changes in the next 10 years, the globe will be trapped in an unavoidable era of heat waves that were unprecedented (前所未有的) for human beings.

1.What may cause students absent-minded according to the text?

A.Video games. B.Text messages.

C.Heat waves. D.Classroom notes.

2.What can be inferred from the second paragraph?

A.Kids often go to the water fountain for lack of water.

B.Extreme heat may lower a kid’s ability to learn.

3.How does the author feel about dealing with the future global warming?

A.Optimistic. B.Uncertain. C.Worried. D.Indifferent.

4.What does the text mainly talk about?

A.The way that global warming continues.

B.The reasons why kids are absent-minded in class.

C.The hotter it grows, the more focused kids become.

D.The hotter it grows, the harder it will be for kids to learn.

 

1.C 2.B 3.C 4.D 【解析】 这是一篇记叙文。文章讲述的是“热天气”对学习的影响。天气越热,孩子们就越难学习。 1.细节理解题。根据第一段最后一句Surprisingly, the problem is about the ongoing heat wave in Denver.可知,令人惊讶的是,问题出在Denver持续的热浪上。由此可知,Heat waves可能导致学生心不在焉。故选C。 2.推理判断题。根据第二段中“If you lose too much water, and you have to keep going to the water fountain, that can take away from their classroom experience.” While nodding off in class on a warm day may seem acceptable for the average teen, Melanie’s observation carries a bigger consequence than dry lips.可知,“如果你失去了太多的水,你不得不持续喝水,这可能会让他们不能上课。”对于一般的青少年来说,在温暖的天气里在课堂上打瞌睡似乎是可以接受的,但梅兰妮的观察比嘴唇干燥更重要。由此可知,酷暑可能会降低孩子的学习能力。故选B。 3.推理判断题。根据最后一段中Humans still have time to lessen the worst consequences of continued global warming. Without the unlikely important changes in the next 10 years, the globe will be trapped in an unavoidable era of heat waves that were unprecedented (前所未有的) for human beings.可知,人类仍有时间减轻持续的全球变暖带来的最坏后果。如果未来10年没有这些不太可能发生的重大变化,全球将陷入一个不可避免的热浪时代,这对人类来说是前所未有的。由此可知,作者对地球的变暖很“担忧”。故选C。 4.主旨大意题。根据第一段中的Surprisingly, the problem is about the ongoing heat wave in Denver.(令人惊讶的是,问题出在Denver持续的热浪上)和最后一段第一句The connection between lost learning and a greater number of hot days is one more example of how climate change is already affecting our lives — and it’s an alarm bell for what we stand to lose in the future.(失去的学习机会和更多的炎热天气之间的联系是气候变化如何影响我们生活的又一个例子——它为我们在未来可能失去的东西敲响了警钟)可知,天气越热,孩子们就越难学习。故选D。

    Upon first look, the world of business is no place for young women. And many people have told my cofounders and me that in many circumstances. Pessimistic though people are about women’s chances in conducting business, three of us female college students, without any experiences, started our business with a greatly aggressive goal: to set up a seaweed farm in North Carolina and grow as much seaweed as possible to help cut down carbon emissions (排放) and pollution filled with nutrition from agricultural activities.

In the beginning, our ideas were either ignored or mocked by the researchers from whom we sought help and advice. But we carried on with our research–if others wouldn’t provide us with answers, we weren’t afraid to try to work them out by ourselves. We experiment on species which could grow in warmer waters, and we had identified potential markets into which we planned to sell the product. We've spent the last two years setting up the first seaweed farm in NC, applying for a patent (专利) and competing with five final teams in front of the United Nations for 2 million.

Despite all of our efforts, many industry experts remained unwilling to take us seriously. But as often happens in business, the same characteristics we were ignored for were, in reality, our biggest competitive advantage. Our age gave us the strength to learn from failure, and our background as environmental scientists, rather than businesswomen, helped us find new marketing opportunities. For every 10 farmers who claimed nobody would ever want to feed their cows seaweed, we found one who was interested. For every 15 cosmetics producers who refused to answer our cold calls, we stuck to the one with an interesting idea for a seaweed lotion.

Over the course of our early business development efforts, we have had access to a wealth of resources, programs, and individuals who work constantly to help us succeed. By staying focused on bringing our ideas to light, our team has demonstrated that entrepreneurship (创业) is exactly the right place for the hopeful.
