A
TheBest Placeto Camp in Each State
Washington-SecondBeach, Olympic National Park
Campers put up their tents right on the sand of thisPacific Northwestbeach. Make a campfire, photograph sunset over the sea and try to absorb this charming spot with your entire being.
Alaska-Bartlett Cove Campground, Glacier (冰川) Bay National Park
In a state full of natural riches,Glacier Bayis a wonder, home to high peaks, whales, 700 miles of coastline, and light blue glaciers that flow directly into the sea. Set within temperate rainforest along Bartlett Cove, the park's only campground is impressively green and an easy jumping-off point for boat tours.
Arizona-Havasupai Campground, Havasupai Reservation
Getting to Havasupai is a challenge. Permits are snatched (剥夺) up almost instantly, and even if you get one it's a 10-mile hike from the border to reach this rural campground that hugs Havasu Creek. Make the journey, however, and you're rewarded with a series of great waterfalls and natural pools.
Arkansas-BuffaloNationalRiver
America's first national river travels 135 miles through the Ozark Mountains, winding its way over rapids, forming peaceful pools and passing rocky cliffs topped by green forest. Plan a float trip and absorb the scenery at
a leisurely pace, pausing for hikes to visitLostValley's caves or the 200-foot waterfalls.

The climate change is already eating into the output of the world's agricultural systems, with productivity much lower than it would have been if humans hadn't rapidly heated the planet, new research has found.
Advances in technology, fertilizer (化肥)use and global trade have allowed food production to keep pace with an increasing global population since the 1960s. But rising temperatures in this time have acted as a handbrake (手刹) to farming productivity of crops, according to the new research, published in Nature Climate Change. Productivity has actuallyslumpedby 21% since 1961, compared to if the world hadn't been affected by global heating.
With the global population set to rise to more than 9 billion by 205, the UN'S Food and Agriculture Organization has estimated that food production will have to increase by about 70%,with annual crop production increasing by almost 1 billion tons and meat production by more than200mtons a year by this point. Meanwhile, global temperatures are rising at a rate that scientists warn is extremely dangerous for human civilization.
“The impact already is larger than I thought it would be,” said Ariel Ortiz-Bobea, an economist atCornellUniversitywho led the research. “It was a big surprise to me. The worry I have is that research and development in agriculture takes decades to translate into higher productivity. The projected temperature increase is so fast that I don't know if we are going to keep pace with that.”
Weston Anderson, a researcher of food security (安全) and climate at Columbia University who didn't take part in the study, said the new research provides fresh insight into the importance of the impact upon agriculture.
“The regions that this paper highlights as experiencing the largest reductions in agricultural productivity-CentralAmericaand theSahel- contain some of the least food secure countries in the world, which is a real concern,” he said.
4. What does the underlined word “slumped” in paragraph 2 mean?
A. Fallen.
B. Gathered.
C. Approached.
D. Benefited.
5. What is Ariel Ortiz-Bobea worried about?
A. Fertilizer is used in food production.
B. Population will rise to over 9 billion.
C. Global temperatures are rising too fast.
D. Agricultural research needs many years.
6. What can we learn about Weston Anderson?
A. He puts forward a different solution.
B. He proposes carrying on with the research.
C. He pays more attention to food insecure regions.
D. He supports improving agricultural productivity.
7. What is the best title for the text?
A. The Impact of Growth in Farm Productivity
B. Productivity in Agriculture is Growing
C. Causes and Effects of Global Heating
D. Rapid Global Heating is Hurting Farm Productivity
C
When you walk with a backpack, do you know how the things inside move from side to side? Now scientists havefigured out how to tap into that movement to produce electricity.
Picture a pendulum (摆锤) fixed to a backpack frame and stabilized with springs on either side. The pack’s weight is attached to the pendulum, so the pendulum swings side to side as you walk.Then a machine is driven by that swinging movement, and spits out electrical current to charge a battery.
Volunteers carried the pack while walking on a running machine and wore masks to measure the flow of O2and CO2. Walking with the slightly swinging 20-pound load, the device (设备) did not significantly affect the volunteers’ metabolic (新陈代谢的) rate compared to when they carried the same weight fixed in place. In fact, the energy-harvesting pack reduced the forces of acceleration they’d feel in a regular pack, which might mean greater comfort for a long hike. And the device did produce a steady trickle (涓流) of electricity. If you up the load to 45 pounds, the swing of the pack could fully charge a smart phone only after 12 hours. The details are in the journal Royal Society Open Science.
The device produces electricity from human movement and has been identified as a workable solution to providing a renewable energy source for portable electronic devices. It is particularly useful for those who work in remote areas, as these people often carry a lot of weight in a backpack for their exploration.
But here’s a realconundrum: the energy-harvesting device currently weighs five pounds. The researchers say that’s about four pounds too many to be a smart alternative to batteries. So they hope that more research lets them lighten the load, to ensure the pack charges you up without weighing you down.
8. What does Paragraph 2 mainly talk about?
A. How the device works.
B. What the device looks like.
C. Who the device is designed for.
D. Why scientists designed the device.
9. Which of the following describes the device?
A. It greatly affected the volunteers metabolic rate.
B. It harvested energy as the volunteers walk.
C. It failed to produce steady electricity.
D. It was useless for a long walk.
10. What does the underlined word “conundrum” in the last paragraph mean?
A. Problem.
B. Method.
C. Bond.
D. Decision.
11. What will the researchers try to do next?
A. Increase the charging speed of their device.
B. Find smarter alternatives to batteries.
C. Reduce the weight of their device.
D. Put their device on the market.
D
Australia’s Great Barrier Reef has lost 50% of its corals (珊瑚) within 30 years, with climate change a key driver of reef disturbance, a new study has found.
Researchers from the ARC Centre of Excellence for Coral Reef Studies, inQueensland, northeasternAustralia, studied coral communities and theirsize along the length of theGreat Barrier Reefbetween 1995 and 2017, finding all coral populations disappear gradually, they said.
Reefs are important to the health of ocean ecosystems — without them, ecosystems break down and ocean life dies.
Coral population decreases happened in both shallow and deep water coral species, experts found, but branching and table-shaped corals — which provide habitats for fish — were worst affected by mass bleaching (漂白) events in 2016.
Warm ocean temperatures are the main reason of coral bleaching. Bleaching doesn’t kill coral immediately, but if temperatures remain high, eventually the coral will die, destroying a natural habitat for many species of ocean life.
“We used to think the Great Barrier Reef is protected by its huge size — but in fact our results show that even the
world’s largest and ly well-protected reef system is increasingly destroyed and in decline,” Terry Hughes, an outstanding professor at the ARC Centre of Excellence for Coral Reef Studies, said.
“There is no time to lose — we must sharply decrease greenhouse gas emissions as soon as possible,” the reporter warned in the paper, published in the Proceedings of the Royal Society journal.
12. What has mainly influenced the coral populations of theGreat Barrier Reef?
A. Destroyed habitats.
B. Climate change.
C. Lack of seafood.
D. Bleaching events.
13. What can we learn from the passage?
A. Many species has been dying out slowly.
B. The size of reefs contributes to their protection.
C. Ocean ecosystems don’t develop without reefs.
D. Bleaching continually disturbs table-shaped corals.
14. What attitude does the reporter hold to the present situation of theGreat Barrier Reef?
A. Worried.
B. Angry.
C. Hopeful.
D. Surprised.
15. What is probably the best title for the passage?
A. Climate change damages theGreat Barrier Reef
B. The Species of ocean Life Are In Danger
C. Greenhouse Gas Emissions Get Worse
D. Sea Ecosystems Are In Decline
