King Canute couldn’t stop the ocean’s tide from rolling in — can Africa hold back the desert?That’s certainly what the continent is tying to do with its proposed “Great Green Wall”, 800km (almost 500 miles) worth of trees that officials hope will stop the advancement of the Sahara Desert, which has been rapidly expanding southward.

The idea was introduced in the 1970s when the once-rich region turned barren (贫瘠的) due to climate change and intensive land use. But it’s not a new idea; China has its own desert vegetation project to hold back the Gobi Desert! Thanks to the Chinese plan, the African project aims to plant 100 million hectares of trees by 2030 across the entire Africa. The initiative is a decade in, and around 15% completed, and there have already been benefits for many communities and wildlife. It’s bringing life back to the continent’s degraded landscapes at an unprecedented scale, providing not only food security and jobs but a reason to stay for the millions who live along its path.

The creators of the wall hope it will bring an urgently needed solution to the threats facing the African continent, creating 10 million jobs in rural areas, as well as preventing 250 million tons of carbon. The initiative is Africa-driven, which for those on the continent, is vital, and may hold the key to success. “The Great Green Wall…is about ownership, and that has been the failure of development aid because people were never identified with it,” said Elvis Paul Tangam, African Union Commissioner for the Sahara and Sahel Great Green Wall Initiative.“But this time they identify. This is the very thing of us!”

The wall may seem like a moonshot, but all the best ideas usually are. As Thomas Sankara, former president of Burkina Faso said in 1985, “You can not carry out fundamental change without a certain degree of madness. The courage to turn your back on the old formulas, the courage to invent the future.”

1. What does Africa’s “Great Green Wall” aim for?
A.Offering more jobs for locals.B.Stopping the expansion of desert.
C.Creating a harmonious society.D.Improving African landscapes.
2. Where did Africa got the inspiration?
A.From their practices of planting trees.B.From the process of stopping flooding.
C.From China’s success in desert control.D.From Africans’ wisdom and hard work.
3. What does “us” underlined in Paragraph 3 refer to?
A.African Unions.B.All advocates.C.Land owners.D.All Africans.
4. How does Thomas Sankara feel about the initiative?
A.Daring.B.Effortless.C.Critical.D.Doubtful.

【推荐1】The world has a plastic problem—and it is increasing.    1     But in the meantime, here are five things you can do to reduce plastic waste now.

1.Replace plastic bags. People use a lot of plastic bags worldwide every year.About 10 percent are used in the United States alone. That’s almost one bag per American per day.    2     In 1993, Denmark was the first country to place a tax(税) on plastic bags.Today, other countries either make customers pay for plastic bags or have banned them completely.

2.Skip the straw(吸管).Today, around 8.3 billion plastic straws pollute the world’s beaches.    3    In 2018, Seattle became the first major U.S.city to ban plastic straws, and many other cities are set to follow its example.

4.Avoid plastic packaging materials.Don’t buy fruit or vegetables in plastic packaging.In the United Kingdom, leaders are calling for supermarkets to have plastic­free areas.They also want to tax plastic take­out containers.

文章大意:本文是一篇说明文。本文讲述曾经帮助美国实现梦想的哈德逊河流遭受严重的污染,但是现在住在山谷里的梦想家们开始反抗,争取权益保护哈德逊河,开启环保运动。

【推荐2】By the twentieth century, New York City had long since reached its destiny of becoming the most powerful city in America. In less than 300 years it had grown from a tiny Dutch outpost in the wilderness to the business capital of the world. It was a city built on dreams,

But it was made out of bricks and cement that had come from the banks of the Hudson. The river which had fed all those dreams was now fading into the background. New York didn’t seem to need the river anymore, except as a sewer. And that’s what it became.

Industry on the river had made some New Yorkers filthy rich. But it had just made the river filthy. Garbage, factory waste, plant chemicals and the raw sewage of the cities and towns along its banks were dumped directly into the river. The water turned greenish brown, except by the GM plant, where it turned red or yellow or whatever color they were painting the cars that day.

The fishing industry collapsed. The few fish that survived were too poisonous to eat. Smog from the factory smoke and dust from the cement plants blanketed the valley. And it was all legal.

Most people don’t start out which dreams of polluting a river. But it was often the result of people chasing their dreams of wealth with little care of how they reached it. The Hudson Valley had always drawn them.

But now there were other dreamers in the valley, with their own dreams of wealth. They dreamed of the wealth of wildlife in a healthy forest, the abundance of fish in oxygen—rich water, and the great fortune of living in a beautiful river valley.

So perhaps it was a matter of time before the two types of dreamers would meet each other—in court. In 1963, Con Edison, New York City’s power company, proposed a plan for constructing the largest hydroelectric pumping station ever built. The plan called for carving out a gigantic hole in the side of majestic Storm King Mountain on the Hudson River.

But then they met Franny Reese, a longtime valley resident with a simple point to make: the mountain could not speak for itself. If she didn’t speak for it, who would?

Franny and a group of like—minded people founded Scenic Hudson and took on the power company in a landmark court case. Con Ed challenged the right of private citizens to participate, but the court sided with the citizens, in the ruling now known as the Scenic Hudson Decision.

After dragging out the case for seven years, Con Ed finally gave up and Storm King survived unblemished. It was the beginning of the environmental movement in this country, and and again, the Hudson Valley was the birthplace.

1. According to the first two paragraphs, the Hudson River that once helped realize people’s dreams was now ______.
A.disappearing from view
B.losing its importance in people’s minds
C.moving farther and farther away from the city
D.remaining important only to those who want to seek their fortune
2. Which of the following is NOT the factor contributing to the pollution of the river?
A.The automotive plant.B.The raw sewage.
C.The fishing industry.D.The cement plants.
3. What does the underlined word “unblemished” probably mean?
A.Unaware.B.Unknown.C.Unharmed.D.Unstable.
4. What can we infer from the passage?
A.Scenic Hudson may be an environmental organization that protects the Hudson River.
B.Con Ed and Franny Reese settled the case out of court.
C.Two types of dreamers signed an agreement in court.
D.The Hudson Valley, once a magnet for dreamers, is now completely abandoned.
