1 . Keep a Moon Diary
Grab a notebook and your favorite pen or pencil, and you’re ready to begin your very own Moon Diary. You’ll discover all kinds of fascinating things about how the moon travels and notice the various phases of the moon.
Before you start you can collect together some books about the moon to learn about it.
Start your Moon Diary by looking for the moon one night and recording all the things you notice. Note the date, time, and weather. Is the moon full? Half full? Or maybe gone entirely? What color does it seem to be?
It takes about 28 days for the moon to make one complete orbit around the Earth. So after four weeks, you’ll have completed your very own Moon Diary!
A.Look back over what you wrote and drew. |
B.You could draw a sad face in the box instead. |
C.Write and draw your observations in your notebook. |
D.Every day for a month, look in the sky and find the moon. |
E.Maybe you’ll decide to keep going with your Moon Diary. |
F.Picture books and stories are a great way to introduce a topic. |
G.Predict what shape the moon will be each night for the next month. |
2 . Jeannette Frescas was not concerned about the Thomas Fire until the fire reached her neighborhood in Ventura, California. “At midnight, I woke up with a flashlight in my face,“ Frescas told CNN.“I looked out of my window and there were flames, a hundred feet, all around us.”
Like many residents, Frescas was caught off guard by the fire that had roared across Southern California for 13 days. She’s one of tens of thousands of residents who got into cars and fled as winds drove the third-largest fire in modern state history through Ventura and Santa Barbara counties.
“What was once a paradise (天堂) was like a war zone (地带),” Frescas said of her apartment, which was destroyed by the fire. “It’s the scariest thing I’ve been through in my entire life.” Ventura resident Patricia Rye woke up to her son-in-law pounding on her door. She didn’t get a chance to pack any valuables. “I didn’t have time to take anything,” Rye said. “My wallet, or any of my personal things.”
The fire was so terrible that more than 8,400 firefighters were working around the clock to save lives and contain (控制) it. Twelve thousand people were evacuated (撤离) in Santa Barbara County, with animals at the local zoo threatened as well. Santa Barbara Zoo closed and many animals were placed into cages in case of possible evacuations. The zoo had kept most animals indoors, away from smoke.
Meanwhile, residents who had evacuated their homes in Ventura County-where the fire began-were allowed to return on Saturday. Jim Holden considered himself lucky that firefighters saved his home and items. “They put a water screen between my house and the house next door that was burning in an attempt to save it,“ he said. “They broke in and they saved my family photos and my computer, and things that they thought would be important to me.”

As students, what can we do to prevent natural disasters
We are called South China Tiger, and we are in danger of extinction.
5 . If you look at the dynamic “Global Temperatures” map on NASA’s website, you can see the historic temperature change over time across the planet as the timeline goes from 1880 to the modern day. By 2019, the entire planet is in red, orange, and yellow colors, indicating temperatures much higher than the historical average in every country and human inhabitance.
If the timeline went to 2023, the map would look even worse. That’s because the summer of 2023 was the hottest ever, according to ocean monitors. July was the hottest month in recorded history. Next July could be worse. Unless we do something quickly, we face dealing with more and more dangerous and expensive natural disasters in the future.
Forest fires sent smoke from Canada across the North American continent, causing New York City to have the worst air quality in its recorded history. Heavy rainstorms fell on Vermont and the Northeastern United States in just a couple of days in the middle of July, which exceeded the amount that area would usually receive in two months and caused extreme damage to homes and businesses. Around the same time, flash flooding in Bucks County, Pennsylvania — north of Philadelphia — killed nearly a dozen people.
Erich Fischer, a researcher specializing in climate studies at the Swiss Federal Institute of Technology, is concerned that natural disasters could get much worse in the future—and in ways we cannot predict. He called for a “strike for climate justice,” which actually took place on Sept. 15, 2023. “The strategy needs to be twofold (双重的) . We need to decrease carbon emissions as much as realistically possible. That is already happening with people using electric cars and other green technologies. At the same time, we also need to find ways to predict the risk of natural disasters ahead of time,” said Erich Fischer.

6 . A forest in Staffordshire (in the UK) transformed into a hi-tech laboratory. Researchers here are investigating how the trees use carbon, and it’s difficult to find out. In an unusual experiment, extra carbon dioxide is piped to the trees, to create the kind of atmospheric conditions expected in the middle of the century. And instruments measure how the forest reacts.
The scientist in charge says there’s still a lot to learn. And he worries that governments and companies are rushing to plant trees as an easy answer to climate change. “If you try and use trees to tidy up the mess that we’re making through emissions, you are putting those trees into a very rapidly changing climate and they will struggle to adapt,” said Professor Rob MacKenzie, University of Birmingham.
This device tracks the movement of carbon dioxide. In a healthy forest, the gas is not only absorbed by the trees but some is released as well. What scientists here are finding out is the way carbon flows into a forest and out of it is a lot more complicated than you might think. So, if mass tree planting is meant to be a solution to tackling climate change, the trees are going to have to be monitored and cared for, over not just decades, but may be centuries as well.
Of all the challenges, the task of planting is the simplest. Shelby Barber from Canada can do an amazing 4,000 trees in a day. “People talking about planting millions billions of trees around the world. Is it possible do you think, physically?” asked BBC.
“It’s definitely possible with the right amount of people, the right group of people. I’ve personally, in three years, planted just over half a million trees.” said Professor Rob MacKenzie.
Once planted, the trees need to survive, and experts are mixing different types to minimize the risk of disease. “It’s a bit like making sure you don’t put all your eggs in one basket, you’re spreading out your risk. And then if one part of that woodland fails, for whatever reason, it gets a disease or it can’t tolerate future climatic conditions, there are other parts of the forest that are healthy and able to fill in those gaps.” said Eleanor Tew of Forestry England.
Suddenly there’s momentum to plant trees on a scale never seen before. So what matters is doing it in a way that ensures the forests thrive — so they really do help with climate change.

9 . Sharks have been swimming in the ocean for millions of years. They were on Earth even before dinosaurs! At the top of the world’s ocean’s food chain, sharks help keep the population of other ocean animals in balance. A large drop in the number of sharks can cause serious problems for all ocean animals. Saving sharks makes sense!
Many people are afraid of sharks. But most sharks are harmless. Only a small percentage of sharks are known to attack humans. They adapt well to new habitats and eat whatever is available. However, today, sharks are in trouble. Nearly one third of the 400 shark species are in danger of extinction, largely due to over-fishing. Each year, tens of millions of sharks are caught and killed just for their fins. The fins are used to make shark fin soup.
Humane Society International(HSI) joined with the Jane Goodall Institute’s Roots and Shoots program and Beijing Zoo to protect sharks. An exhibit at the zoo, “The Price Behind the Taste — Protect Sharks. Don’t Eat Shark Fins”, was designed to tell people that shark finning is cruel and unnecessary. It’s hoped that the activity will help put an end to the practice.
Shark fin soup is also eaten in the United States. In fact, the numbers of some shark species in US waters have dropped 90 percent in the last 30 years. To slow the fall, laws against the sale of shark fins have been passed in several states, including Hawaii, Oregon, Washington, and California.

10 . A British company has proposed releasing a GM(genetically modified) strain of the diamondback moth (菱形斑纹蛾), which has been developed to help reduce the population of these vegetable-eating insects.
Male diamondback moths carrying a deadly gene would be released which would cause their off springs (后代) to die almost immediately. Then the fall in their numbers could help to increase crop yields for farmers.
Oxitec, the company which came up with the idea, hopes to begin trials next year but faces opposition from groups who say the untested technology could threaten wildlife and human health.
“Mass releases of GM insects into the British countryside would be impossible to recall if anything went wrong. Changing one part of an ecosystem can have knock-on effects on others in ways that are poorly understood. This could include an increase in different types of pests. Wildlife that feeds on insects could be harmed if there are changes to their food supply” said Dr Helen Wallace, the director of Gene-Watch UK, who has sat on government advisory bodies.
Hadyn Parry, Oxitec’s chief executive, said there was demand from farmers for the technology and that using GM insects to kill the pests that feed on food crops is better for the environment than chemical sprays. The firm, which is supported by grants from the taxpayer, is developing a number of GM insects that would be used in Britain and around the world to protect crops and combat disease in humans.
Oxitec has contacted the Health and Safety Executive (HSE) to ask what controls, if any, should be put in place around GM moth trials. A spokesman said that while its officials and advisers have discussed Oxitec’s plans, there is yet to be a formal application for a trial. Consequently the department has not reached a view on whether it should go ahead.
