Litter is everywhere, doing great harm
The story began with his 6-year-old daughter. One day they were going on a hike when the girl noticed a broken plastic tub (浴盆) in a river. She said, “Daddy, that doesn't go there.”That took Kirschner by surprise. He, like many adults, had become so used to seeing the rubbish

2 . About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?
Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is !
Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately (微妙地) balanced.
The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.
Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions (限制) to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!

4 . Leading a sustainable(不破坏环境的)lifestyle doesn’t require you to have to make great changes to your home, and this kind of transformation doesn’t have to be an exhausting exercise.
Make changes to your water drinking habits. Have you ever thought about how many single-use plastic bottles you use a year? If you should ever perform such a count, you’d find yourself well into three figures, or maybe even four.
Reduce your transport emission. If you want to be a more sustainable traveler, you should seek to reduce the carbon emissions you produce by avoiding driving. Of course, avoiding motor vehicles entirely isn’t always going to be a practical choice for you. There’re, however, still things you can do to be more sustainable.
You have the power to make a sustainable change to your lifestyle—take the above advice and don’t waste it
A.Turn to solar energy. |
B.Avoid wasting valuable resources. |
C.The best thing you can do is cycle, walk or run. |
D.Two choices you have are sharing cars and taking public transport. |
E.There’re many easy and simple things you can do to be more sustainable. |
F.Another change you can make in this instance is to stop using plastic straws. |
G.Drinking water like this might be quick, easy and convenient but it’s not sustainable. |
5 . On a sunny afternoon, Andreas Fath climbed out of a river in Paducah. A small crowd was on hand to witness his setting a new world record. This man had just finished swimming the entire length of the Tennessee River—1,049 kilometers. And he did it in just 34 days!
As a chemist from Hochshule Furtwangen University, the 52-year-old man had taken on this swim for science. His primary goal was not to get his name into Guinness World Records. What really drove this swim was a desire to make people aware of the seriousness of water pollution.
Fath’s crew included his family. Martin Knoll, who helped organize Fath’s swim, also took par t. Knoll is an environmental scientist at the University of the South. He describes this swim as a vehicle for getting people interested in water quality and how we pollute water without realizing it.
It took Fath 34 days to swim the river’s length. Along the way, his crew took measurements of the water’s temperature and pH. They also recorded weather and the speed of the river’s currents (涌流). As for the Tennessee River, they collected daily water samples. A small plastic device attached to one leg of Fath’s wet suit sampled the chemical pollutants (污染物) through which he swam. Finally, Fath’s goal is to use such data to know what on earth results in water pollution. Then he wants to find ways to keep those chemicals out of the water.
Back in Germany, Fath and his students have finished examining their data. They plan to publish their findings soon. Identifying materials that hide in the river isn’t only important for the animals that live there. “It’s also a way to protect human health,” says Fath.

6 . Jane Goodall, the well-known scientist, is starting Trees for Jane on Tuesday, joining a global campaign to fight climate change by planting a trillion trees by 2030.
Goodall made it clear that planting is just one part of Trees for Jane. “The key is protecting existing forest because those big trees have already stored CO2,” she said in a National Geographic interview. Donations to Trees for Jane will support local groups working to stop destroying trees. And those who plant are asked to agree to care for the trees and monitor them until they’re mature(成熟的).
Of course, tree planting is not a substitute for reducing emissions (排放), said Susan Cook-Patton, senior forest restoration scientist for The Nature Conservancy. “The most important action is to reduce fossil fuel emissions. However, even if we rapidly reduce emissions, we’re still going to need to remove carbon from the atmosphere to prevent catastrophic warming. That’s why carbon removal approaches like re-growing trees remain important.”
Some tree-planting efforts have come under fire from some scientists as being ineffective since many programs don’t plant native species, essentially creating tree farms, not helping forests. And Cook-Patton’s message is clear, “Plant the right trees, in the right places, in the right way.” This means planting native trees where they historically lived.
Goodall said this agrees with the goal of Trees for Jane. She, noting that Trees for Jane encourages people to plant trees themselves or donate to support global efforts, said her love for trees dates back to her childhood. Nearly eight decades later, she is working tirelessly and selflessly to share the gift of trees with the entire world, for the good of the planet.

7 . Nearly 40 years ago, Peter Harrison, a marine ecologist witnessed the first recorded large-scale coral bleaching(珊瑚白化)event. Diving in the Great Barrier Reef(大堡礁), he was shocked by the scene before him. "The reef was made up of healthy corals and badly bleached white corals, like the beginnings of a ghost city," he says. Just months before, the same site was filled with colorful tropical life.
"Many of the hundreds of corals that I'd carefully tagged and monitored finally died," he says. "It was shocking and made me aware of just how weak these corals really are.”
Coral exists together with photosynthetic algae(藻类), which live in its tissues and provide essential nutrition(and coloration). But high temperatures and other stresses can turn algae poisonous. When this occurs, the algae may die or be removed by the coral, a process known as bleaching because the coral's clear tissue and white calcium carbonate skeleton(碳酸钙骨骼)are exposed. If the coral can't reestablish its link with algae, it will starve or become ill.
The widespread destruction Harrison saw in 1982 was repeated on many other Pacific Ocean reefs that year and the next. In 1997 and 1998 the phenomenon went global, killing some 16 percent of the world's corals. With rising temperatures, pollution, disease, increased ocean acidity, invasive species, and other dangers, Harrison's ghost cities are expanding
Scientists suppose that about four decades ago severe bleaching occurred roughly every 25 years, giving corals time to recover. But bleaching events are coming faster now—about every six years—and in some places soon they could begin to happen annually.
"The absolute key is dealing with global warming," says marine biologist Terry Hughes. "No matter how much we clean up the water, the reefs will die." In 2016, a record-hot year in a string of them, 91 percent of the reefs that consist of the Great Barrier Reef bleached.

9 . There are many wetlands(湿地) in China and some of them have become the world’s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng,Jiangsu Province. They are home for many different kinds of birds and animals. The world’s largest Milu Deer Nature Reserve(自然保护区) is in them. More than 700 milu deer live freely there. There are not many red-crowned cranes in the world, but every winter you can see some in the Red-crowned Cranes Nature Reserve in the Yellow Sea Wetlands.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine,too. They are really good places for wildlife(野生生物). Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
Luckily, more and more people are beginning to realize the important of wetlands and wildlife. Every year,on February 2nd,many activities are held to tell people more about wetlands.
1. Usually the weather in the wetlands is ________.A.hot | B.pleasant | C.cold | D.dry |
A.April 22 | B.June 25 | C.February 2 | D.March 22 |
A.they are home for wildlife | B.they can prevent flood |
C.they can offer food to the animals and birds | D.all of the above |
A.China’s Wetlands Have All Entered the World’s List |
B.Wetlands—Home for Wildlife and Human Beings |
C.Special Animals in the Chinese Yellow Sea Wetlands |
