The climate change in California has caused terrible damage to California's marine ecosystems.Untold billions of sea stars，or starfish，from at least 20 species disappeared from the entire Pacific coast because of the marine heatwaves.In the absence of sunflower sea stars，a major predator for sea urchins （海膽），the urchin populations exploded.They laid waste to kelp forests （海草林） already weakened by high ocean temperatures.
   However，Central California's kelp ecosystems have done somewhat better than those in Northern California.A new study led by Joshua Smith，an ecologist at the University of California，examines the role sea otter （海獺） populations一a natural predator for urchins一play in preserving existing kelp forests in the Monterey Bay.
   The research project spanned three years，during which intensive under-water produced some very interesting data about sea otter behavior.Sea otters have very high metabolisms （新陳代謝） that keep them warm in icy waters and which also make them greedy consumers of shellfish，urchin，and fish一sea otters can eat 25 percent of their body weight in food in a day.At the observed sites，as the urchin population grew，the otter 's diet shifted to become more heavily dependent on urchins.In fact，the otters were eating three times as many urchins as they had been before 2014.As a result，they provided crucial protection from urchins to the kelp forests.
   The fact that otters were able to contribute to the health of the surviving kelp forests by keeping urchin populations in check provides Smith with hope for the forests' continued survival. "The important thing is that the urchins are ultimately reduced，" he says."The sea otters have maintained patches of kelp forest that can then help refill the barren areas to enhance the recovery of forests."

1．When she first started learning about the climate change from one of her elders，F(xiàn)awn Sharp was invited on a helicopter flight over the Olympic Mountains to survey the Mount Anderson glacier.But the glacier was gone，melted by the warming climate.Sharp had a deep sense of loss when she discovered the glacier wasn't there anymore.
   Loss is a growing issue for people working and living on the front lines of climate change.And that gave Jennifer Wren Atkinson，a full-time lecturer at the University of Washington Bothell，US，an idea for a class.
   This term，she taught students on the Bothell campus about the emotional burdens of environmental studies.She used the experiences of Native American tribes（部落），scientists and activists，and asked her 24 students to face the reality that there is no easy fix - that "this is such an intractable problem that they're going to be dealing with it for the rest of their lives"．
   Student Cody Dillon used to be a climate science skeptic （懷疑論者）.Then he did his own reading and research，and changed his mind.Dillon wasn't going into environmental work - he was a computer-science major.Yet，the potential for a worldwide environmental catastrophe seemed so real to him five years ago that he quit his job and became a full-time volunteer for an environmental group that worked on restoration （恢復(fù)） projects.
   Six months into the work，he decided that Atkinson's class was just what he was looking for - a place where he could discuss his concerns about a changing climate.
Atkinson said she hopes the class helped her students prepare themselves for the amount of environmental loss that will happen over their lifetimes.
   "We are already changing the planet - so many species are going to be lost，displaced or massively impacted，" she said. "The future isn't going to be what they imagined."

（1）Why did the author mention the case of Fawn Sharp？

A．To lay a basis for Fawn Sharp's further research.
B．To prove Fawn Sharp's work is similar to Atkinson's.
C．To lead into the issue of loss caused by climate change.
D．To show scientists' concern about the Mount Anderson glacier.
（2）What's the main purpose of Atkinson's class？

A．To explore how different people deal with climate change.
B．To get students more concerned about the environmental issue.
C．To find solutions to the environmental issue of Olympic Mountains.
D．To teach students how to conduct research about the environment.
（3）Which of the following best explains "intractable" underlined in Paragraph 3？

A．Simple.
B．Difficult.
C．Common.
D．Interesting.
（4）How did Atkinson's class influence Dillon？

A．It made him work as a part-time volunteer for restoration projects.
B．It made him realise a planet-wide climate disaster would happen.
C．It encouraged him to be more involved in environmental protection.
D．It discouraged him to work on restoration projects for the environment.

2．Africa Water Week --nearly one billion people around the world have no access to drinking water，that lack of clean water association with un-proper hygiene and shortage of toilets kills 3.3 million a year．And this is a common problem in many parts of the developing world，but its effect is not widely known，according to experts at the Pulitzer Center on Crisis Reporting．
   As part of the World Water Day tradition，the center is screening films about international water issues at the Environmental Film Festival in Washington，D．C．The films describe a variety of conflicts over water．
   "The challenge in presenting these films，" says Peter Sawyer，project coordinator at the Pulitzer Center on Crisis Reporting， "is to share with a wider audience the urgent issues surrounding water．" "Our goal for this screening is to just get these issues out there，" he says． "We don't feel that they attract public attention and we think that they should because they are really important．"
   In Dhaka's Challenge，filmmaker Stephen Sapienza explores one of the fastest growing cities in Asia．He says one-third of the 15 million people in the Bangladeshi capital live in places where safe water is limited．Each year 400，000 newcomers join Dhaka's urban poor．City water from Dhaka's Water and Sewer Authority （WASA） comes at a price，available only to land owners．The film records how a non-profit group helped change the law to give the same equal water rights to the urban poor．
   Diabalok Sing Ha，who is the group's founder，said， "A win-win situation actually occurred because Dhaka WASA wanted their incomes and on the other hand，poor people wanted the service and they immediately see the economic advantage of getting Dhaka WASA water supply because that is cheap，so they immediately buy in．"
   "My story was just trying to point out that these problems are solvable on some level even if you have to start small and it's possible in the long run to save many lives，" says Sapienza．

（1）Which of the following is the main purpose of the films？

A．To show the number of people lacking clean water．
B．To let more people know the serious water problems．
C．To attract people to pay attention to the world conflicts．
D．To get people to have a good knowledge of water．
（2）What does Paragraph 4 mainly talk about？

A．Ways to get cheap water．
B．The film Dhaka's Challenge．
C．Filmmaker Stephen Sapienza．
D．A non-profit group．
（3）Which of the following does Diabalok Sing Ha agree with？

A．Most people can't afford the water supply．
B．Rich people in Dhaka will buy in at once．
C．Poor people in Dhaka need the service of water．
D．Dhaka WAS A will see soon the economic advantage．
（4）What does Sapienza intend to tell us by making the film Dhaka's Challenge？

A．The problem of water can possibly be solved．
B．All the people cannot get city water from WASA．
C．A win-win situation is expected by every filmmaker．
D．Dhaka WASA is very popular with the local people．
