1 . Green architecture is designed in an environmentally-friendly way. Many people think interest in green architecture has only begun in recent years.
To make it, much of green architecture focuses on building intelligently. For example, plumbing systems (管道系统) may be designed to use less water while still functioning normally.
Many architects build environmentally to show people that it’s possible. And they want to show the fact that being environmentally-friendly does not have to make a building bad-looking.
The green design can be kept in mind when we build various future buildings, ranging from a private home to a tall office building. Green designs can also be applied to remodeling (改造) and repairing existing buildings.
| A．The goal is to make a building prettier. |
| B．Not many buildings have great green designs. |
| C．A green building’s design need solve many problems. |
| D．In fact, humans have tried green architecture for thousands of years. |
| E．After all, pulling down a building can quite damage the environment. |
| F．Actually, many of the green designs can make a building more beautiful. |
| G．And smart lighting would turn off when people are not around to save energy. |

3 . “Is there going to be a flood?” asked Daniel. He looked nervously at his dad and mom. They both looked worried. Dad was completely wet and dirty. He and some other men in town had spent the morning piling bags of sand on top of the levee (防洪堤) along the river. For years the levee had kept the Mississippi from flooding its banks. After three straight days of rain, though, the water grew higher and higher. If the levee broke, Daniel’s neighborhood would be flooded for sure.
“We’ll be fine,” Dad placed a reassuring hand on Daniel’s shoulder. Outside, lightning flashed, followed by distant thunder. “Just in case,” said Dad. “I think we should start moving some things to Uncle Mike’s house.” Uncle Mike lived farther away from the river on higher ground. “And we’ll take everything we need to cook and eat upstairs,” he said, “like camping out in our own house.”
By nightfall, everything the family needed had been moved upstairs. Dad had taken their new couch and TV to Uncle Mike’s. Daniel helped his dad tie a fishing boat to the front (门廊). “Just in case,” said Dad.
Lying in bed that night, Daniel tossed and turned. He could hear the heavy rain beating on the roof. “Everything will be all right,” he said to himself just before falling asleep.
Several hours later, the sound of sirens (警报器) woke Daniel from a sound sleep. He sat straight up in bed, his heart pounding. In rushed Mom ,“Get dressed, Daniel! The levee just broke! We’ re leaving. We have no other choice.”
A few minutes later they all got into the fishing boat, leaving behind just about everything they owned. Daniel asked, “We’re going to lose everything, aren’t we?”
“No, not everything”, said Mom, pulling him close. We’ll always have each other.”
“That’s right,” said Dad. “We may lose the house, but we can always rebuild it. We can’t ever lose our home, though, because home is us.”

5 . Facing fierce mountain wildfires, a young man from Chongqing stepped forward to join the battle against flames.
When seeing a mountain fire break out in the city’s Fuling district on the evening of Aug 17, Yu Qiupeng, a student from Chongqing Industry and Trade Polytechnic, said: “I just felt a ‘boom’ in my head”. Without giving a second thought, he set out to join the fight against the fire.
Because of traffic restrictions, Yu had to walk to the fire scene. At around 10 pm, Yu arrived at the fire site and started working with other volunteers. When cleaning a water pipe, Yu accidentally burned his hand. “I looked up and saw a fireman next to me pouring water on another fireman who had just rushed out of the fire, and the water immediately vaporized (蒸发) into smoke,” said Yu. “I really wanted to cry at that time.”
After hours of hard efforts by firefighters and volunteers, the fire was extinguished. On the evening of Aug 18, hot embers (余烬) at two sites of the mountain fire began to burn up again. Once again Yu joined the volunteer group to put out the flames. This time, the condition of the land was more difficult. Yu needed to transport supplies on the extremely hot slope (山坡), He carried a backpack full of supplies and went back and forth more than 10 times under the burning sun.
Yu’s deeds won praise online. Video clips spreading online show him running, fighting the fire and digging isolation strips (隔离带) in the fire scenes. While people were trying to recognize the young man, Yu’s hometown also caught fire because of the continuous heat waves. The 18-year-old headed to the fire scene for a third time.
When his teacher asked: “Did you know how dangerous it was?” Yu said: “I didn’t think about it.”

7 . If you’re a fan of hummingbirds(蜂鸟), then you probably know that at night they lower their body temperatures greatly by dropping into an energy-saving state of inactivity called torpor(麻木). A new study finds that the birds have more than one level of torpor. “There have been a few signs that this ability to fine-tune thermoregulation(温度调节)is possible,” said the lead author Anusha Shankar.
Shankar and her colleagues used a special method to track the body temperatures of three hummingbird species in Arizona: the blue-throated mountaingem, Rivoli’s hummingbird, and the black-chinned hummingbird. They measured the temperatures emitted from the skin around the eyes of the birds and found that differences in heat generation at various stages are noticeable
The normal daytime body temperature of a hummingbird is more than 100 ℉, even in cold weather. During shallow torpor, their body temperature drops by about 20 ℉. In deep torpor, the bird keeps a body temperature 50 ℉ below its normal daytime temperature. If human body temperature were to drop mere 3 degrees from the standard 98.6 ℉, we’d be in a state of hypothermia(低体温症)and, unlike hummingbirds, we would need outside help to get warm again.
“In this study, we found that the smallest bird used deep torpor every night,” said Shankar. “The bigger birds sometimes use deep torpor and sometimes shallow torpor, and sometimes no torpor at all.”
Shallow torpor may have developed to balance energy saving with the cost of deep torpor. In deep torpor, a hummingbird is much more likely to be affected by disease because its immune system(免疫系统)shuts down. And what’s more, it would get inadequate sleep and be easily harmed by its enemies.
Torpor is not the same as sleep. Sleep uses much more energy and serves many important functions. Daily torpor also differs from hibernation(冬眠). Hibernating animals enter a low-energy state for weeks or months at a time, while hummingbirds can enter torpor every night. But the researchers say their studies were done under laboratory conditions, not the conditions a bird would encounter in the wild. They say more research is needed to understand thermoregulation in birds.

8 . Since 1958, pandas have almost become China’s “unofficial ambassadors” around the globe. Here are some of the best-known ones.
Chi Chi
Perhaps the most famous panda in history was Chi Chi that ended up in the London Zoo almost by accident in 1958 and lived there until her death in 1972. For that entire time, she was the only panda living in a western country. After she arrived in London, Chi Chi became the original model for the WWF logo (徽标) on the group’s founding in 1961.
Ling Ling and Hsing Hsing
As a state gift from China, the first two pandas arrived at their new home in the US: the Smithsonian’s National Zoo on April 16, 1972. Over the next 20 years, Ling Ling had given birth to five babies. Sadly, none of them survived for more than a few days.
Mei Xiang and Tian Tian
On December 6, 2000, the Smithsonian’s National Zoo got another pair of pandas from China. Unlike Ling Ling and Hsing Hsing, the Zoo’s second pair of pandas are on loan.
Since they came to the Zoo, Mei Xiang and Tian Tian have had four babies: Tai Shan, Bao Bao, Bei Bei and Xiao Qi Ji. The latter was born on August 21, 2020, and is still living with his parents in the Zoo. At age 4, all his brothers and sisters had been returned to China under an agreement.
Jing Jing and Si Hai
On October 19. 2022, China lent Qatar two pandas just one month ahead of the World Cup in the country. Jing Jing, a 4—year—old male, has been given the Arabic name Suhail, and the 3-year-old female Si Hai has been given the Arabic name Thuraya. They will live in Qatar for fifteen years.

10 . In recent years, we have always seen different kinds of new energy vehicles on the road frequently, but do you know anything about them?
In the 21st century, with the increasing shortage of resources such as oil and natural gas, the issue of non-renewable resources has become a major concern. The traditional industry uses mostly oil as a fuel, and the carbon dioxide produced by burning oil hurts the air. The vehicle emissions (排放) contribute to global warming and other poisonous gases cause serious air pollution.
In response to the problem of vehicle pollution, countries and regions worldwide are setting increasingly strict standards for vehicle emissions. To cope with the increasing severity of vehicle emission standards, the major car manufacturers(制造商) are now mainly adopting methods to improve the technology related to the engines of conventional energy vehicles. Although this has improved the quality of emissions, it will be increasingly difficult to upgrade the technology. At this point, the development of new energy vehicles has become a new option for manufacturers, as the production and use of new energy vehicles will fundamentally solve the problem of vehicle emissions. Therefore, the development of new energy vehicles are a necessity and a general trend.
New energy vehicles are proposed as opposed to traditional vehicles, which are mainly fuelled by petrol. A new energy vehicle is a type of vehicle that runs on clean energy sources, using new energy sources as the fuel commonly used to power the car and provide the drive energy for the vehicle. New energy vehicles can be divided into several categories, such-as pure electric vehicles, fuel cell electric vehicles, hybrid (混合动力) vehicles, and so on. In addition, new energy vehicles have the advantage of low energy consumption and low-carbon environmental protection.
However, although new energy vehicles follow the concept of sustainable development, there are still many problems and challenges in the development of new energy vehicle research and production. For instance, many issues require specialist technicians and solutions, and further breakthroughs are needed in key technology areas. In addition, the efficiency of new energy use needs to be further improved, making it difficult to form an industrial-scale operation in a short period.
