1 . Several years ago, Jason Box, a scientist from Ohio, flew 31 giant rolls of white plastic to a glacier (冰川) in Greenland. He and his team spread them across 10,000 feet of ice, then left. His idea was that the white blanket would reflect back the rays of the sun, keeping the ice cool below. When he came back to check the results, he found it worked. Exposed ice had melted faster than covered ice. He had not only saved two feet of glacier in a short time. No coal plants were shut down, no jobs were lost, and nobody was taxed or fired. Just the sort of fix we’re looking for.
“Thank you, but no thank you.” says Ralph King, a climate scientist. He told Grey Childs. author and commentator, that people think technology can save the planet, “but there are other things we need to deal with, like consumption. They burned $50,000 just for the helicopter” to bring the plastic to the glacier. This experiment, quote-unquote, gives people false hope that climate change can be fixed without changing human behavior. It can’t. Technology won’t give us a free ride.
Individuals respond to climate change differently. Climatologist Kelly Smith is hardly alone in her prediction that someday soon we won’t be climate victims, we will be climate Choosers. More scientists agree with her that if the human race survives. The engineers will get smarter, the tools will get better, and one day we will control the climate. but that then? “Just the mention of us controlling the climate sent a small shiver down my back, Grey writes.” “Something sounded wrong about stopping ice by our own will,” he says.
Me? I like it better when the earth takes care of itself, I guess one day we will have to run the place, but for the moment, sitting at my desk, looking out at the trees bending wildly and the wind howling, I’m happy not to be in charge.

2 . Most of Florida is a flat peninsula (半岛) with water on three sides and houses built as close to the shoreline as possible. For one thing we are more frequently the target of hurricanes than any other state; for another, our geography makes us more easily to be hurt by rising seas.
A news story about climate change in Florida popped up. Historically, scientists believed mangroves (红树林) didn’t live farther north than Cedar Key, in the middle of Florida’s Big Bend. But that’s not the case anymore. Samantha Chapman, a biology professor who’s been studying how Florida’s mangroves have been migrating (迁移), found them up near the St Mary’s River, which forms the border between Florida and Georgia. It seems that they soon be marching through Georgia and becoming a thriving new component of coastal habitats.
But a coastal biologist named Blair Witherington took issue on the matter. The mangroves weren’t spreading into a new territory, he pointed out. They were entering areas that had been classified as saltmarsh (盐沼), where the landscape was dominated by cordgrass. Saltmarsh and mangrove create very different habitats that attract a very different set of animals. “When one community replaces the other, this diversity is lost,” Witherington remarked. Changing the animals’ habitat has the potential to influence the whole food chain, making a widespread difference.
What was driving this? “Mangroves can survive a short freeze, but not a prolonged, hard freeze. By combing through the weather records kept by the state’s orange juice industry, biologists have been able to document that Florida is having fewer prolonged hard freezes than it used to. Then the mangroves have adapted by expanding their range.” Samantha explained.
“They’ve adapted in another way, too. Not only are the mangroves spreading into areas that once were unfriendly to them, but they have also changed their life cycle to speed things up. Normally it takes them about 15 years of growth before they start making seeds. Now, as they get into these marshes, they’re producing seeds when they’ re only a couple of years old,” Samantha said.
The problem with having too many mangroves by the sea is that climate change may overwhelm them. A study by the US Geological Survey said sea level rise could wipe out mangroves all along the Florida coast. So, here’s the question we humans have to consider: Nature is finding ways to adapt to how we’ve changed the climate. What are we doing to adapt to it? Or at least slow it down?

3 . Priscilla Ouchida’s “energy efficient” house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000 three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness.
Experts finally traced the cause of her illness. The level of formaldehyde gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting.
The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. “The indoor environment was dirty long before energy conservation came along,” says Moschandreas, a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.”
The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn’t worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom built up to dangerous levels.

| B．Because energy used to be inexpensive. |
| C．Because environmental protection was given top priority. |
| D．Because they were technically unavoidable. |
| A．Energy Conservation | B．House Building Crisis |

4 . The worldwide 20th century “Green Revolution”, which saw huge year-by-year increases in global grain yields (产量),was fueled by the development in the 1960s of new high-yielding dwarfed (矮小) varieties known as Green Revolution Varieties (GRVs).
These dwarfed GRVs are common all over the world in today’s wheat and rice crops. Because they are dwarfed, with short stems, GRVs devote relatively more resources than tall plants to the growth of grains rather than stems, and are less likely to suffer yield losses from wind and rain damage. However, the growth of GRVs requires farmers to use large amounts of nitrogen fertilizers (氮肥) in their fields. These fertilizers are costly to farmers and cause extensive damage to the natural environment. The development of new GRVs combining high yields with reduced fertilizer requirements is thus a global agricultural goal.
Researchers at the University of Oxford and the Chinese Academy of Science have discovered for the first time a gene that can help reach the goal. Comparing 36 different dwarfed rice varieties, the researchers identified a novel natural gene that helps increase the rate at which plants make use of nitrogen from the soil. This gene, called GRF4, can increase the amount of a protein (蛋白质) in plant cells. GRF4 is actually a promoter that encourages the activity of other genes—genes that promote nitrogen uptake (摄入). Professor Harberd said, “Increasing GRF4 levels could contribute to an increase in the grain yields of GRVs, especially at low fertilizer input levels.”
The researchers say the latest rice variety containing GRVs should now become a major target for farmers in increasing crop yields and fertilizer use efficiency, with the aim of achieving the global grain yield increases necessary to feed a growing world population at a reduced environmental cost. It is very urgent at the moment.
Professor Harberd added, “This study is an example of how studying fundamental science objectives can lead rapidly to potential solutions to global challenges. It shows how the discovery can enable chances for food security and future new green revolutions.”

5 . Bangkok’s Grand Palace is the busiest tourist stop in the city. People keep coming because the Grand Palace could arguably be called the birthplace of Bangkok
How to Get to the Grand Palace
Making your own way to the Grand Palace in Bangkok is more enjoyable and rewarding. Moving around by river taxi is inexpensive. Additionally, you’ll have a good excuse to see the Chao Phraya River up close. Going by boat won’t make you caught in traffic jams. It will let you see beautiful river scenery!
People staying in the Khao San Road area may choose to walk (around 20 — 25 minutes) to the Grand Palace.
Opening Hours
The Grand Palace is open seven days a week from 8:30 a. m. until 3:30 p. m. Occasionally, the Grand Palace does actually close for official visits and state functions. However, this is rare. Don’t believe any driver who states the Grand Palace is closed. If the statement of closure is too convincing, confirm it by calling: +6626235500 ext.3100.
Entrance Fees
Considering that temples in Thailand are often free, the 500 baht (around $16) per person entrance fee at the Grand Palace is relatively expensive. Thai nationals do not have to pay. An audio tour can be rented for an additional 200 baht. Besides, human guides are available for hire. Choose an official guide rather than accepting someone’s offer on the outside.
Dress Standards at the Grand Palace
To show enough respect, you shouldn’t wear sleeveless shirts in any temple or state building in Thailand. But unlike many of the other temples, dress standards are strictly required at the Grand Palace.
Men must wear long trousers, women must cover legs to just above the knee.
Don’t wear shirts with religious themes or symbols of death on them.
You may be told outside that flip-flops (人字拖鞋) are unacceptable footwear.

6 . Pre-school children who spend time together take on one another's personalities, a new research has found. The study shows that environment plays a key role in shaping people's personalities. While genetics still forms the central part of the human psyche (心理), the research finds that personality traits (特征) are "contagious" (传染的) among children. "Our finding flies in the face of common assumptions that personality can't be changed," said Dr. Jennifer Neal, co-author of the study.
The researchers studied the personalities and social networks of two pre-school classes for a full school year. One of the classes was a set of three-year-olds, and the other a set of four-year-olds. Children whose friends were hard-working or outgoing gradually took on these personality traits over time. Psychology expert Dr. Emily Dublin said kids are having a far bigger effect on each other than people may realize.
The new study is not the first to explore the contagious effects of personality traits. A 2015 psychology study found that rudeness at work can be contagious as it travels from person to person "like a disease". The study found that seeing a boss being rude to an employee was enough to cause people to be rude to those around them.
The researchers questioned 6,000 people on the social "climate" in their workplaces, which included offices, hotels and restaurants. They found 75 percent of those who took part said they had been treated rudely at least once in the past year. And the study also suggests that merely seeing other people being subjected to rudeness made it more likely that a person would treat their colleagues in the same way. Rudeness could include leaving someone off an invite to a company event, sending unkind emails, finding fault with others or failing to give praise.
Dr. Torkelson believes companies need to be more aware of the harm that rudeness in the workplace can do as it can damage the working environment. She said better training could help to fight against the problem.

7 . When birds’ habitat is destroyed, some species don’t make it while others survive. But what happens at the very beginning of the process, just as a bird’s habitat starts to change? Research in Argentina’s Monte Desert has provided some answers. There are lots of trees, bushes, grasses and flowering plants in the protected parts of the desert. With so many options, most seed-eating birds choose to focus on large grass seeds. The birds can get all the energy and nutrients they need with minimal effort.
But when cattle show up to graze the desert’s natural landscape, birds face changes in food supply. Some birds are happy to change their diets in response. But others, not so much. And it’s the ones set in their ways that are at the highest risk. Understanding how birds react to grazing can help researchers solve the problem of those species.
Ecologists from the Argentine Arid Zones Research Institute compared soil samples from the desert’s Nacunan biosphere reserve to samples from two neighboring cattle farms. It was discovered that grass seeds — the birds’ favorites — were just one-quarter as likely to be found on the farms compared with the reserve. Next, they caught birds to see what they were eating. The Common Diuca-Finch and the Rufous-Collared Sparrow had adjusted their diets, choosing to eat their less preferred options on the farms, even while they still focused on large grass seeds in the reserve.
Meanwhile, the Many-Colored Chaco Finch and the Ringed Warbling-Finch were apparently unable to change their diets. Even on the farms, they worked hard to find the few grass seeds available. If they burn more energy searching for food than they get from the few grass seeds they find, they could starve. At best, their inflexible dietary could limit their ability to reproduce or to care for their young.
Studies like this can help predict which species are at higher risk and help farmers protect these poor species, even while allowing their livestock to graze. For example, the farmers can plant new species for their cattle that will also be more delicious and nutritious for local seed-eating birds. The cows won’t care about the menu change — but the birds sure will.

10 . Most forest fires are caused by human carelessness or ignorance. Forest fire prevention, therefore, is mainly a problem of creating better understanding of the importance of forests, an awareness of the danger of fire in the woods, and a sense of personal responsibility to safeguard the forests from danger. This is not an easy job.
Careless smokers are responsible for thousands of forest fires each year. Many of these are started when cigarette butts (烟蒂) and matches are thrown from automobiles. Others are caused by hunters, hikers, fishermen, or woods workers who are careless in disposing (处理) of their smoking materials. The Forest Service has posted rules in many of the National Forests that ban smoking except in certain designated (指示) areas. Many of the states have laws against throwing lighted materials from automobiles. The prevention of smoker-caused fires, however, depends upon changing the attitudes and behavior of millions of people who smoke in dangerous area.
The most important natural cause of fire is lightning. This accounts for 11 per cent of forest fires on protected land for the entire nation. In the Western States, lightning causes a much higher percentage of fires than it does in the East.
Advances in knowledge of fire weather are helping forest protection forces to know when to be alert to lightning-caused fires. Adequate and well-equipped forces can control them quickly and hold the damage to a minimum. Experiments in “seeding” thunder clouds to prevent or control the lightning itself have been in process for many years, but new breakthroughs are needed for any significant reduction in the fires lightning starts.
