3 . What fisherman Moul Thun from a remote island in the Mekong River, in northern Cambodia, didn’t know was that stingray he hooked would eventually be named the largest recorded freshwater fish. For Zeb Hogan, who’s been documenting large freshwater fishes for almost two decades, the discovery of the stingray, which was released alive back into the river, filled him with hope. “It proves these underwater big fish, which are in critical danger, still exist,’’ says Hogan.
Hogan’s pursuit for big fish, called the Megafishes Project and supported by National Geographic Society , began in 2005 when fishermen in northern Thailand pulled a 646-pound cafish out of the Mekong River. The species is known that it was the largest, that is, the heaviest-ever caught in the area.
Arriving at the island, the team found Thun’s fish, a female that appeared to be in good health. It was more than 13 feet from nose to tail. The researchers were shocked to see her weight at 661 pounds. She set a new world record. The original aim of the Megafishes Project was to find, study, and protect the world’s largest freshwater fishes. The project focused on species that could grow to at least the size of a human and that lived only in freshwater.
Hogan initially drew up a list of roughly 30 species to focus on.
The challenge, as Hogan soon learned, was that many of these fish are hard to find. They live in remote, inaccessible places, and often in deep waters. Early on in the search, there were relatively few scientists studying them.
What was clear was that the river giants were shrinking in number, threatened by a host of factors including overfishing, water pollution, and the presence of dams, which block migrating fish from completing their life cycles. As Hogan’s work progressed, its focus increasingly turned to conservation. “It was never about just finding the biggest fish,” Hogan says, “but looking for ways to protect these extraordinary animals that, in some cases, have been on Earth for hundreds of millions of years but are now drifting out of entities.”

4 . Rainforests provide much of the world’s oxygen. People have been trying to protect them for years. But another type of forest, the cloud forest, is just as important to humans.
These forests are at the tops of mountains, generally near the equator(赤道). These wet, wooded mountaintops are mainly in African and Central and South American countries. They are called “cloud forests” because their height allows for the formation of clouds among the trees. The trees in these forests pull water out of the clouds. The water gathers on the leaves and falls into small rivers below, which flow into towns at the bottom of the mountain. The yearly rainfall in these areas is about 180 centimetres. Cloud forests can pull in up to 60 percent of that. The water is important to the plants and the people in the area. It helps them survive.
These forests are being destroyed at an increasing speed. Trees are being cut down, and roads are being built in their place. Some people have a goal to get government money to protect the forests. But they have had little success so far. Another way is to take the place of the destroyed plants with new ones. That, too, has been difficult because the plants are so special. There’s plenty of work to be done, but saving the cloud forests is still possible with creative solutions.

5 . Many of the vegetables we grow in our gardens produce seeds (种子), which can grow into plants if collected and stored correctly. Late summer is the perfect time to start collecting them.
Make sure the seeds are from plants that you have planted well for many years. These are plants in their normal forms.
Hybridized (杂交) plants usually produce the vegetables sold in big food stores.They are created from two or more different kinds of plants to get the best qualities of each. Trying to grow seeds from these plants will not lead to happy results. This kind of plants will not have the expected results but instead carry the genes (基因) of just one of its parents.
Many plants become cross-pollinated (异花授粉) in the garden. Bees, flies, animals and wind spread pollen (花粉) from one plant to another. To ensure the seeds will grow into plants, give them space.
To avoid cross-pollination surprises, plant only one kind of each vegetable from which you can harvest seeds.
| A．When will the seeds come off the flower? |
| B．It is impossible to tell which parent that will be. |
| C．What should you do if you want to save tomato seeds? |
| D．Their seeds will produce plants as good as their parents. |
| E．Put seeds in a cool, dry place in a covered glass container. |
| F．Place different kinds of the same crop as far apart as possible. |
| G．In areas with cold winters, simply leave plants in the ground over winter. |
6 . A Natural History of the Future
Over the past century, humans have made great technological achievements with which we have found ways to control nature. From river dams (大坝)to huge one-crop fields, we continue to try to change nature for our goals so much that it seems we may be in danger of influencing it seriously.
In A Natural History of the Future, biologist Rob Dunn thinks that nothing could be further from the truth: rather than asking whether nature will let us live, we’d better ask whether we will let nature last. Although we try our best, or worst, to control the biological world, life has its own laws, and no matter what man does, he cannot change them.
Explaining several basic laws of ecology (生态), Dunn shows why life cannot be stopped. We grow one single crop on the field, only to find new life appearing to attack them. We throw away poisonous (有毒的) waste, only to find microbes (微生物) taking it over. And even in the London Tube, we have seen a new type of mosquito appear to take advantage of a place that is clearly not fit to live. Life will not follow our plans. Instead, Dunn shows us the future of living things and the challenges that the next generation may face.
A Natural History of the Future sets a new standard for understanding the different kinds of life and our future as a kind of creature.

9 . African penguins stand only 50 cm tall. Like people, each penguin has its own voice. They live along the southern coast of Africa. Like all the other penguins, they hunt fish in the ocean and lay eggs on land. But they are smaller than their well-known cousins in Antarctica (南极洲) and larger than little penguins in Australia and blue penguins in New Zealand. But the African penguins have a problem—they are endangered.
The African penguins used to nest (筑巢) underground in the bird poop (粪便), which came from the penguins and other seabirds. Over hundreds of years, it had built up to form a thick layer as deep as 3 meters.
However, in the 1860s, people began collecting the poop to use it on farms. Now there’s no more poop to make nests. The penguins have to lay their eggs in the open. As a result, the penguins often get too hot. When the parents leave the eggs to cool themselves down in the water, other animals can easily find the eggs and eat them.
To solve the problem, the scientists set up an artificial nest project in 2016. They came up with criteria for the nest. It had to protect penguin eggs from being eaten. It couldn’t flood in the rain. And it needed to keep penguin families cool. The scientists built 15 kinds of nests to find the perfect one. Finally two of them stood out. Both of them could let air flow through. The scientists plan to build more than 2,500 nests for the African penguins in the future. They hope the new nests can help increase the number of the endangered birds.

It was a lovely spring morning in the mountains of my home. Here was full of natural atmosphere. The sky was blue, the sun was warm, and the air was fresh. As driving along the winding road, I could see thousands of wild flowers in bloom. When I turned round, I slowed down as I saw some volunteers picking up garbage along the side of the road. I just smiled as I saw them doing some cleaning in spring for Mother Earth and my mind suddenly floated back in time to another spring morning long ago.
When my children were younger, I used to walk along a small route around the lake near my home. It was also on a spring morning that I noticed much garbage lying along the route. The next day, I brought a big garbage bag and started to slowly pick up the garbage along my way. All kinds of deserted objects lay all over the floor. There were pop cans, plastic water bottles, wrappers for candy bars, empty chip bags, pieces of broken fishing line and even an old shoe. Every time I stopped, I picked up a piece of garbage. And I even fished some garbage out of the edge of the water. By the time I circled the lake, the garbage bag had been nearly full.
Tired but happy, I put the bag in an empty garbage can. I stopped before I headed home and took one last look at the lake as the sun set. It looked more beautiful than ever and I felt like the angels were looking down upon it with me and sharing my smiles.
I always think that at times this world’s problems can seem overwhelming and you may wonder what you can do to make a difference. But the truth is that every good thing you do matters a lot! I do believe every time I stop to pick up a single piece of garbage, I can make a difference. As my children are adults now, I decide to spend more time protecting the environment.
