1 . The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface. An estimated 97 percent of the world’s water is found in the ocean. Because of this, the ocean has considerable impact on weather, temperature, and the food supply of humans and other organisms. The ocean remains a mystery. More than 80 percent of the ocean has never been mapped, explored, or even seen by humans. A far greater percentage of the surfaces of the moon and the planet Mars has been mapped and studied than of our own ocean floor.
Although there is much more to learn, oceanographers have already made some amazing discoveries. For example, we know that the ocean contains towering mountain ranges and deep valleys, just like those on land. The peak of the world’s tallest mountain—Mount Qomolangma in the Himalaya, measuring 8848. 86 meters high-would not even break the surface of the water if it was placed in the Pacific Ocean’s Mariana Trench or Philippine Trench, two of the deepest parts of the ocean. On the other hand, the Atlantic Ocean is relatively shallow because large parts of its seafloor are made up of continental shelves—parts of the continents that extend far out into the ocean. The average depth of the entire ocean is 3.720 meters.
It is unknown how many different species call the ocean their home. With many ocean ecosystems suffering from rising sea temperatures, pollution, and other problems, some oceanographers believe the number of species is dropping. Still, there may be many positive surprises awaiting oceanographers in the years ahead. It could be that more than 90 percent of the ocean’s species are still undiscovered, with some scientists estimating that there are anywhere between a few hundred thousand and a few million more to be discovered. Currently, scientists know of around 226,000 ocean species. Since the ocean is so vast, there is plenty for future oceanographers from all corners of the globe to explore and discover.

2 . Work starts early on White Gate Farm in East Lyme, Connecticut. By 7 a. m., farm manager Dan Wood was at the East Lyme Post Office dropping off a box of fresh produce that later in the day would be delivered by mail to Chelsea Gubbins, who lives across town.
White Gate Farm is a member of Farmers Post, a pilot programme that enables smallholder farms across eastern Connecticut to ship fresh produce and other farm products to local households through the United States Postal Service (USPS). Farmers Post takes advantage of a USPS programme called Connect Local that allows small businesses to offer same-day and next-day delivery at a fixed low cost.
Food remains in the fields because either market prices are too low or the cost of the workforce is too high, or because the size and shape of the produce make it unattractive to stores. Each year, around 10 million tons of crops never get harvested, causing about 16% of total US food loss and waste.
“Food that is wasted has a much larger influence than just the loss of the food itself,” says Julia Kurnik, senior director of Innovation Start-ups at WWF. “Everything that went into growing it goes out the window as well—the water, the land, and the energy. And as the food breaks down, it produces greenhouse gases. The bad effects amplify greatly.”
Besides reducing food waste, selling farm products directly to local customers cuts down on the cross-country shipping of food grown in California or elsewhere. This reduces the so-called food miles that researchers believe cause about 6% of the world’s greenhouse gases. Fruits and vegetables, which are often transported out of season and require refrigeration, produce lots of greenhouse gases between farms and people’s plates.
Wood understands that Farmers Post can help to end that waste. “Farming is kind of like cooking for a big group.” he says. “This is helping us get right on the money, using almost 100% of what we grow and harvest.”

3 . My kitchen may be the best kitchen on the planet. That is because when I look out of its window can see the west side of Grandeur Peak. Grandeur Peak is one of the most attractive mountains in central Wasatch, with its animals, trees, morning clouds, evening sunset, and the mountain’s paragliders (滑翔伞运动员).
The number of paragliders flying above Grandeur Peak has grown over the past 15 years, so much so that they have become part of the mountain. But during the past year they have largely disappeared. Some paragliders told me that the wind became too strong to fly in. The wind is too strong! Is this another character of our changing climate (气候)? Will paragliding be a sport affected by a warming planet? Utah has been much windier in the past few years. For me, a scientist who studies living things, it is easy to believe that our future will be windier. This year it’s getting super-hot, and the planet is warming faster than scientists expected. I can’t help but worry that the future of paragliding in Utah is not bright.
I’m writing to the brave people who fly from Grandeur Peak with beautiful wings. I want you to join Clean The Dam Air, a group that’ s working hard to fight climate change and air pollution — I’m part of it too. We are introducing a measure, which aims to remove the state sales tax (税) on grocery store food and put a carbon tax on fossil fuels (化石燃料) in its place: gas, electricity produced from fossil fuels, and natural gas. The goal isn’t to make taxes higher. The idea is to encourage everyone to reduce their use of fossil fuels. So, paragliders, join us. Now is the time to take care of our planet. If we succeed, then Utah can be an example to others in fighting climate change.

4 . On November 8th, a tornado, the most powerful in the past 70 years, hit Jersey, causing great damages to the area and leaving the residents in great panic.
“Suddenly, the windows of the waiting room exploded in and dragged everything inside. My cars have been completely destroyed by branches and fences, and my garden is completely gone. There’s no furniture, no fence; everything has been thrown everywhere. At first there was lightning but then a strange noise and strange darkness came over the whole house. It was like being in a scary scene in the movie The Wizard of Oz,” Ashleigh Quail-Charleston, a Jersey resident, told the Bailiwick Express after the tornado that struck overnight on November 1—2 during Storm Ciaran.
The consequence looked like a bomb had gone off: cars hit, roofs with holes, windows broken. “A huge tree leans drunkenly against a block of flats. Piles of branches are piled optionally and pavements are covered with pieces,” said Chris Stone at BBC Radio Jersey. The tornado was powerful and exceptionally rare, caused by a severe thunderstorm that had sent out intense lightning and huge hailstones described as “ice bombs”. The Tornado and Storm Research Organization (Torro) and Jersey Met Office revealed the tornado left a trail of damages 8 km long across the island, and rated its intensity as T6 on an international scale of tornado power.
According to Torro records, this was the most powerful tornado to strike anywhere in the British Isles or Channel Islands since December 7th, 1954 when a tornado struck west London, leaving tremendous devastation, with Gunnersbury railway station torn apart, roofs torn off houses and one car even thrown through the air.
Tornados during Storm Ciaran also hit Sompting in West Sussex and Loders in Dorset. One resident in Loders, Sophie van Hensbergen, described the moment, saying, “The tornado struck with a very, very powerful whistling sound and the windows looked as though we were in a car wash.”

5 . Coming into the town of Santa Catarina Palopó, in the highlands of Lake Atitlan in Guatemala, the first thing you notice is the bright colors. Most of the buildings along the main street are eye-catching, deep blues and greens, dotted with red and yellow to form diverse patterns and designs.
Santa Catarina Palopó was once a sleepy town of 5, 000 people, most of them dependent on agricultural work. But as agriculture began to dry up here, poverty came. To deal with poverty and promote econ on growth through tourism, a small but creative group of laborers, artisans, domestic workers and stay-at-home moms created the Pintando Santa Catarina Palopó project.
The project aimed to paint all 850 homes and buildings in bright colors to change the hillside town into a work of art. “We wanted to paint the houses with colors and figures that represent the community” says the project’s executive director Stephany Blanco. “Families can choose designs for their house that are representative of the family.”
One of the most representative characteristics of the region is the blue huipil, a traditional blouse which has been worn commonly by local women since the 16th century. That deep sky blue was chosen the primary color-for the Pintando project, with secondary colors found in the sunsets and the nearby lake to make the design more attractive. Inspiration was also found in local culture, symbols such as volcanoes, flowers, and the national bird of Guatemala.
Each week, local artists, community members and tourists pick up paintbrushes to make buildings colorful. “At first, the idea of the project was uncertain, but now you can see a considerable difference in the town,” Melissa Whitbeck said. “The color of the buildings is believed to improve the quality-of life of the people. It uplifts the people’s mood and encourages them to be proud of their hometown.”

6 . Should we hide in the “Triangle (三角) of Life” when the earthquake comes?
At 1:39 on June 15, a magnitude (里氏) 3.1 earthquake occurred in Qingpu District, Shanghai, with a focal depth of 8 kilometers. Earthquakes are one of the major natural disasters, so how to avoid danger and self rescue during earthquakes has become a topic of great concern.
There has always been a saying on the Internet that when an earthquake comes, collapsed objects and solid large objects will form a triangular space around them(the “Triangle of Life area”), and hiding in this area will have a greater probability of survival, which many people believe deeply.
In this regard, the China Earthquake Administration said that although observing the ruins after the earthquake, we can find that there are similar triangular spaces in some places.
However, when an earthquake occurs, people cannot know in advance the way of the earthquake, the direction of the collapse of buildings or objects, and it is difficult to know where there will be the so-called “Triangle of Life”.
The “Triangle of Life area” was proposed by an American disaster relief worker named Kupp, who believed that traditional self-help methods such as drilling tables were no longer suitable for people living in modern buildings. The collapsed floor structure would crush the tables or beds for refuge, and only hiding in the triangle area could survive.
Although the “Triangle of Life area” self-help method has been popular for more than ten years. However, the American Red Cross, the California State Emergency Service Office and earthquake experts have all pointed out the irrationality of the “Triangle of Life”. The Chinese Ministry of Emergency Management has also provided a refutation explanation.
In fact, after an earthquake, the internationally recognized most reliable method of self rescue is ‘lying on the ground, blocking, and holding onto your hands’. You should lie down, squat down, or sit down, try to lower the center of gravity of the body, and protect important parts such as the head, neck, eyes, and mouth and nose.
1. What information can we learn about the “Triangle of Life” in the first three paragraphs?| A．The Triangle of Life area is an official definition. |
| B．Many people believe in the “Triangle of Life”. |
| C．The earthquake in Shanghai has caused panic among the masses. |

7 . An owl (猫头鹰) named Flaco escaped New York’s Central Park Zoo last week after his cage was broken. This set off a bird-hunt of police officers and park rangers (护林员). Zoo officials worried that Flaco, who had been kept in his zoo cage for 13 years, may have lost the survival abilities he needed in the wild. They placed some of his favorite treats in the open air to attempt to trap him.
Flaco was not fooled. Instead, he was sighted flying over5th Avenue, and Central Park’s skating rink. A number of New Yorkers came into Central Park to try to catch a glimpse of Flaco, taking photos with excitement.
But this week, zoo officials announced they accepted that Flaco remained in Central Park because he had been seen bringing up bones and fur from the park’s community of rats. “He has been very successful at hunting and consuming lots of rats in the park.” zoo officials told the New York Post.“ And that’s amazing. He’s hunting on his own. He’s flying better. Flaceo really seems to be enjoying himself out there.”
There is a caution attached to this story of an owl who is making it on his own in the city that never sleeps. Owls are nocturnal. They go around searching for food at night. They sleep during the day, or try to, like lots of people who work the overnight shift. Yet some New Yorkers who don’t know proper bird-watching behavior reportedly see Flaco sleep in a tree during the day, and begin to shout at him. It interrupts his sleep. Flaco can’t try to say “shh, shh” with the traditional New York reply. After all, a bird can’t give someone the bird.
1. Why were zoo officials concerned about Flaco’s ability to survive?| A．Because his favourite food was too little. | B．Because he might be attacked by police. |
| C．Because his cage was severely damaged. | D．Because he was kept in his cage for long. |
| A．He has adapted to the wild. | B．He has found his previous home. |
| C．He still faces great challenges. | D．He dislikes the rats in the park. |
| A．Scary-looking. | B．Shy and quiet. |
| C．Active at night. | D．Badly-behaved. |

9 . Steller or Northern Sea Lions are sometimes confused with California Sea Lions but are much larger and lighter in color. Males may grow to 11 feet in length and weigh almost 2,500 pounds.
Stellers are not often seen in bays or rivers. Steller pups are born on offshore islands from mid-May to mid-July and weigh 35—50 pounds.
The current population of Steller Sea Lions is about 40,000 along the entire Pacific coast. There is great concern about this species. The western Aleutian stock has dropped by 80 percent in the last 30 years. In 1997, the western stock in Alaska was listed as endangered.

| B．Reasons for this decline are not known. |
| C．The male has a thick neck and looks like a lion. |
| D．They spend about half their time on land and half in water. |
| E．Mothers stay with pups for one to two weeks before hunting at sea. |
| F．They forbid the killing, harming or disturbance of any sea mammal. |
| G．Females are much smaller, growing to 9 feet in length and weighing up to 1,000 pounds. |
10 . Time is running short to address climate change, but there are possible and effective solutions on the table, according to a new UN climate report released in March.
Only swift, dramatic, and sustained emission (排放) cuts will be enough to meet the world’s climate goals, according to the new report from the Intergovernmental Panel on Climate Change (IPCC), a body of climate experts that regularly summarize the state of this issue.
“We are walking when we should be running fast,” said Hoesung Lee, IPCC chair, in a press conference announcing the report in March. To limit warming to 1.5℃ above preindustrial levels, the target set by international climate agreements, annual greenhouse-gas emission will need to be cut by nearly half between now and 2030, according to the report. It calculates that the results from actions taken now will be clear in global temperature trends within two decades.
“We already have the technology and the know-how to get the job done,” said Inger Andersen, executive director of UN Environment Programme, during the press conference. “Stopping climate change will still be complicated, and long-term emission cuts may largely rely on technologies, like carbon dioxide removal, that are still unproven at scale. In addition to technological advances, cutting emission in industries that are difficult to transform will involve many factors.”
But in the near term, there’s a clear path forward for the emission cuts needed to put the planet on the right track. There are some of the tasks with the lowest cost and highest potential to address climate change during this decade, such as developing wind and solar power, cutting methane (甲烷) emission from fossil-fuel production and waste, protecting natural ecosystems that trap carbon, and using energy efficiently in vehicles, homes, and industries.
