2、ia in the eastern Pacific Ocean.The researchers say they recognized a local of 67 species (物种) between 2014 and 2016, during what was described as a “marine heatwave”Marine heatwaves were explained in the study as “a period of extreme sea surface temperatures lasting for days to months”The 20142016

3、heatwave is thought to be the largest ever recorded.The warm water later moved southward toward California.The warmer waters were partly a product of El Nio conditions during the same period, researchers noted.El Nio develops when winds off the coast of South America weaken.This enables the warm wat

4、er in the western Pacific to move eastward.El Nio often causes ocean temperatures in the area to rise between 2 to 4 degrees Celsius, the study found.The researchers reported that 37 of the 67 species they studied had never before been observed so far north as California.These creatures are native t

5、o an area hundreds of kilometers to the south, mainly around Baja California in Mexico.A few were even found north of California, off the state of Oregon.The northward travel of so many different sea creatures was considered “unprecedented” (史无前例的) by the researchers.Among the species found in the s

9、g northward.解析：选B细节理解题。由第三段中的El Nio develops when winds off the coast of South America weaken.可知，南美洲减弱的风促使了厄尔尼诺现象的产生。3Why does the author mention the meateating sea slug in Paragraph 4?ATo point out that ocean environment becomes worse.BTo suggest that sea creatures need separate living space.CTo pr

10、ove that many kinds of sea life can adapt to warmer waters.DTo evidence that ocean temperatures along California are higher than before.解析：选D推理判断题。由第四段内容可知，所有研究的67个物种中，有37个在加利福尼亚州北部从未被观察，这是因为加利福尼亚州沿岸的海洋温度比以前高。作者在第四段中提到了食肉海蛞蝓就是为了证明加利福尼亚州沿岸的海洋温度比以前高了。4What can be inferred from the passage?AThe heatwav

12、扰乱了许多海洋生物的生活。BPlastics remain one of the mostused materials for making many things.Things made of plastics can be very strong and last a long time.Plastics are also much lighter than metal and can easily be formed into different shapes.Plastics can take hundreds of years to break down on their own.A

13、nd very few kinds are highly recyclable.A team of researchers working at the US Department of Energy says it has created a kind of plastic that could lead to products that are 100 percent recyclable.It recently reported the discovery in a study in the journal Nature Chemistry.The researchers say the

14、 new material is a plastic polymer (聚合体) called polydiketoenamine, or PDK.The team reports the material can be broken down in parts at the molecular (分子的) level.It can then be built up again to form plastics of different shapes, textures and colors.The researchers say this process can be repeated ov

15、er and over again without the plastic material losing any performance or quality.“Most plastics were never made to be recycled, ” lead researcher Peter Christensen said in a statement.“ But we have discovered a new way to assemble plastics that takes recycling into consideration from a molecular per

16、spective.”Many plastics have different chemicals added to them to make them more useful and powerful.The problem is that these chemicals attach to the monomers (单体)，which remain in plastics even after the material gets processed at a recycling plant.The research team reported that, with the newly di

17、scovered PDK material, the monomers could be recovered and separated from any chemical additives.Next, the researchers plan to develop PDK plastics “with a wide range of thermal and mechanical properties”These plastics could be used for many kinds of cloth, as well as things such as 3D printed mater

18、ials and foams.In addition, the team is trying to include plantbased materials in the process.语篇解读：本文是一篇说明文。文章主要介绍了一个研究团队正在研究一种新型的塑料，这种塑料更容易降解，更耐用且可以循环利用。5What is the first paragraph mainly about?APlastics are never highly recyclable.BPlastics are widely used in our lives.CPlastics have both advanta

19、ges and disadvantages.DPlastics take hundreds of years to break down.解析：选C段落大意题。根据文章第一段的Things made of plastics can be very strong and last a long time .And very few kinds are highly recyclable.可知，塑料结实耐用，更易成型；需要上百年才能降解，且几乎不能循环利用；所以本段既讲了塑料的优点也讲了缺点。故选C。6What does the underlined word “It” in Paragraph

20、3 refer to?AThe new material.BThe research team.CThe molecular level.DThe producing process.解析：选A词义猜测题。根据前句The team reports the material can be broken down in parts at the molecular (分子的)level.和画线词后面的can then be built up again to form plastics of different shapes, textures and colors可知，it指代的是前文提到的新材
