1 . As ice melts in West Antarctica the ground beneath is quickly rising---a process that could prevent the catastrophic(灾难性的) collapse of ice sheets, according to researchers.
A study published in the journal Science provides a glimmer(一丝;一线) of hope for a region affected by climate change. In recent years, several studies have warned the ice sheet, which contributes to a quarter of melted ice worldwide annually, is very easy to break up. Scientists fear even slightly melting could cause global sea levels to rise by 3 meters.
Researchers at the Technical University of Denmark set out to answer how the bedrock underneath the ice sheet of West Antarctica behaves as the ice melts. To study the land, the team analyzed data collected by high-precision GPS equipment positioned on remote rock formations in West Antarctica, which measured movements of the land down to the millimeter over a 10-year period.
“After a heroic effort to install and maintain the network of sensors in one of the least accessible places on the planet, the team has been rewarded with incredibly valuable data, which tell an incredible story about the Barth,” wrote Valentina Barletta.
The team found that the Earth was pushing the bedrock to rise faster than expected. In 2014, the surface rose by 41 millimeters: four to five times quicker than predicted. In 100 years, the land could be up to 10 meters higher than it is currently.
It is hoped that as the ice melts, the Earth's crust(地壳) will bounce back much faster than previously expected. In turn, this could stabilize what the researchers described as the "catastrophic collapse" of the ice sheet.
Barletta told Newsweek the ice sheet will never be stable if global warming becomes too extreme. “Reducing the greenhouse gas will give the ice sheet a better chance of survival because that would allow some known and unknown feedback(反馈) to create better conditions for the ice,” she said.

3 . Edward Wilson is America’s, if not the world’s, leading naturalist. In The Future of Life, he takes us on a tour of the world’s natural resources. How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity (生物多样性) of our earth.
Wilson begins with an open letter to the pioneer in environment protection, Henry David Thoreau. He compares today’s Walden Pond with that of Thoreau’s day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Can the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?
Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species (物种) are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.
At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may as well read and act on the ideas in this book.

Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five metres above sea level. Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country's days are numbered.
But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24 cm over the past 100 years. Experts say that it will have sunk another 24 cm by 2050. A century ago, St. Mark's Square, the lowest point in the city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, Tuvalu's rising sea level is caused by global warming.
The average global temperature has increased by almost 0. 5 centigrade degrees over the past century, scientists expect it to rise by extra 1.3 degrees over the next 100 years.
Warmer weather makes glaciers(冰川) melt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen 10.25 cm in the last 100 years.
The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century.
Should this come true, the sea will swallow up millions of homes and the world will be flooded with "climate refugees" looking for somewhere to live.

| B．they are both sinking into the mud where they stand |
| C．they will disappear in the future |
| D．their trouble is caused by global warming |
| A．People who are forced away from their homeland by climate. |
| B．Climate changes. |
| C．Rare animals. |
| D．Climate effect. |
| A．Tuvalu's nine little islands are less than five meters above the sea level. |
| B．The average global temperature has risen by 13 centigrade degrees over the past 100 years. |
| C．The warmer temperature causes the sea level to rise. |
| D．There will be huge climate changes unless the warming is stopped. |
