Experts say that a big part of the problem is related to food：Less ice means less krill(磷虾), a cornerstone(基石) of the Antarctic ecosystem anda mainstay of a penguin’s diet.“When you look at all penguins they are largely in trouble，” said Oxford University penguinologist Tom Hart, who spends a few months every year observing penguins along the Antarctic coast.“We’re so concerned because we’re seeing great changes to their populations. They’re probably not going to go extinct anytime soon, but the environment is changing very fast.”Emperor penguins, Adelies and chinstraps, for example, live entirely in the Antarctic. According to the International Union for Conservation of Nature(IUCN), both emperor penguins and Adelies are considered “near threatened”. Even populations of chinstraps, not usually considered a vulnerable(易危的) species, have “declined by up to 50 percent in the las t 30 years”， Hart said. “The general public doesn’t realize that penguin populations are declining so fast.”In an interview with the BBC in 2009, Professor Hart warned that emperor penguins could face nearextinction by the end of the century if global warming continued at its present rate.“Regardless of their environmental preferences, we see a connection between climate change and penguin populations through the loss of habitat of their main food source，” Dr. Wayne Trivelpiece, the report’s lead author said. “As warming continues, the loss of krill will have a farreaching effect throughout the Antarctic ecosystem.”Since krill feed on phytoplankton(浮游植物) that grow under ice cover, warming waters and disappearing sea ice have contributed to decreasing Antarctic krill populations. According to Al Jazeera, other recent studies have shown that krill in the Southern Ocean may have declined by about 80 percent since the 1970s.“Simply put, without krill, most of the life forms in the Antarctic would disappear，”National Geographic said.【解题导语】本文是一篇说明文。

Unit 22 Environmental Protection李仕才一、阅读理解。
Following the crowd may not always be in a person's best interest.But new research suggests that teens who get along with their friends may end up healthier as adults.Scientists have known that close friendships help boost health.That's true for both teens and adults.The finding inspired Joseph Allen，a psychologist at the University of Virginia，and his team to study whether experiences during teen years would influence adult health.So they followed 171 teens，starting when the kids were just 13.They interviewed each one every year for five years，and also spoke to these teens' closest friends，who provided additional information about the quality of their friendships.The same 171 people were interviewed again at ages 25,26 and 27.This time, the questions surveyed each person's overall health.When the researchers analyzed the data，they found a strong connection between a teen's behavior and adult health.Teens who had close friends grew up to be the healthier adults.Whether teens held back their feelings or expressed them to close friends also influenced later health.Those who held back their feelings were more likely to be sick as adults.The connection held up even after the scientists accounted for other possible influences on health.Weight，family income and drug use were all examined.So were mental health issues，such as anxiety and depression.And in these people，such other factors did not explain adult health as well as teen friendships did.Getting along with the crowd may have benefits，says Allen，but there are also drawbacks.Teens who are more independent tend to do better at school and work.And peer pressure may lead some kids to engage in risky behavior，such as smoking，drinking or using drugs.Dealing with it is an ongoing challenge，Allen acknowledges.“Finding the right balance is the key.Teens shouldn't lose heart for not finding this easy.”And，he adds，“Parents need to be understanding about the pressures teens face.”1．Where can you probably read this passage?A．Science fiction.B．Health column.C．Fashion magazine.D．Entertainment newspaper.2．We can learn from Allen's study that ________.A．many other factors have a greater influence on adult health than teen friendshipsB．mental health issues have nothing to do with adult healthC．the same 171 teens were interviewed each year from 13 to 27D．the teens who couldn't express themselves grew up to be unhealthy3．According to what Allen said，we can know that ________.A．in order to do better at school，teens should not follow the crowdB．though it's challenging for teens to deal with peer pressure，they should not give upC．teens will engage in smoking，drinking or using drugs when facing peer pressureD．parents should understand their teens and stop them going with friends4．What can be inferred from the passage?A．There is nothing bad for teens to follow the crowd.B．Close friendships are the most important for people's health.C．Teen friendships may help teens become healthier adults.D．Adult health is only influenced by teen friendships.【解题导语】研究表明，与朋友较少或者没有朋友的青少年相比，有朋友的青少年在长大后更健康。

2019-2020年高中英语 Unit22 Environmental Protection难句.剖析.拓展北师大版选修81. In the last few decades, scientists have reached consensus and reported that human beings are causing changes in the Earth’s climate—something previously seen as beyond our control.在过去的几十里, 科学家一致认为, 人类正在造成地球气候的变化——这是一种原来被认为是超出我们控制能力的现象。
剖析：这是一个主从复合句, scientists have reached consensus and reported 是主句, in the last few decades是时间状语, that引导宾语从句human beings are causing changes in the Earth’s climate, something...是changes的同位语。
previously seen 是过去分词作定语, 等于that was previously seen, as“就像……一样”, sth. be seen as“被作为……看待”。
beyond our control“在我们的控制之外”。
拓展：过去分词作定语相当于一个被动语态的定语从句, 前提是当从句的主语和主句的主语相同时, 才能把从句缩略为过去分词, 如果主句的主语和从句主语不相同, 要用介词with 构成with复合结构——with sth. done。

In the freezer,of course.That's what scientists might have thought when they were looking for a safe place to store ice from mountain glaciers(冰川) from around the world.They've decided to store ice in Antarctica(南极) because global warming is causing some of the glaciers in places like the Alps to melt.Jerome Chappellaz of the French National Center for Scientific Research is involved in creating an ice vault(地下室) there.He says,“We are probably the only scientific community whose sample(样本) is in danger of disappearing from the face of the planet.If you work on rocks or on tree rings,the raw material is still here and will be for many centuries.”And why do scientists need to study ice from the Alps for example? Ice formed on the top of a mountain is made of snow accumulated over thousands of years.Trapped air bubbles(气泡) contain samples of the atmosphere that existed when that ice was formed.Ice is a record of climate.By examining ice,we know carbon dioxide in the atmosphere is higher now than in the last three million years.Researchers use this kind of data to build computer models and try to predict what might happen in the future.The ice vault will be housed in a snow cave at the Concordia Research Station,which is operated by scientists from France and Italy.The ice samples will be sealed in bags and placed 10 meters below the surface,at a constant temperature of 50℃.This will put the scientists' minds at rest.Losing the ice samples would be a disaster,and nobody wants to see a mine of scientific knowledge lost forever in a giant pool.语篇导读本文为说明文。
科学家们决定在南极建立地下室储存冰雪样本，以帮助了解和预测全球气候变化。
1．What makes Antarctica a safe place to store ice?A．Its large mountains.B．Its function as a freezer.C．The abundant ice samples there.D．The absence of global warming.解析B细节理解题。
根据第一段可知，科学家们把南极当“冰箱”来储存冰雪样本，故选B项。
2．Why does Jerome compare ice with rocks and tree rings?A．To show it's necessary to store ice.B．To show it's more valuable to study ice.C．To show ice disappears very quickly.D．To show ice should be stored at home.解析A推理判断题。
根据第二段Jerome所说的话可知，相较于研究岩石和树木年轮的科学家(他们的样本可以存在数个世纪),研究气候的科学家是唯一面临研究样本会消失的(由于气候变暖，冰川融化)科研群体，重在说明储存冰雪样本的必要性，故选A项。
3．What is the researchers' purpose of studying ice?A．To learn about climate.B．To learn about the Alps.C．To trap air bubbles.D．To reduce carbon dioxide.解析A细节理解题。
