五、回答问题。(★★☆,建议用时: 5分钟)
  China has many rivers, with a total of 45,203 rivers flowing across the country, each covering an area of more than 50 square kilometres.Among them, the Yangtze River and the Yellow River are the most famous, known as the“mother rivers” of Chinese civilization.For thousands of years, they have nurtured generations of Chinese people, making the surrounding areas thrive as “lands of fish and rice” with rich soil and plenty of water.These rivers can be both gentle, quietly irrigating (灌溉) farmlands, and powerful, showcasing their wild energy during the rainy season.
For thousands of years, Chinese people have built irrigation systems and maintained riverbanks to keep rivers healthy.In 2017, a new river protection policy was launched (推出): local government leaders took on the role of “river chiefs”, directly responsible for monitoring water quality, cleaning up pollution, and preventing illegal (非法的) activities that harm rivers.
  Thanks to the hard work, great changes have taken place in recent years.Polluted sections are gradually clearing up, wetlands along the rivers have become homes for various birds, and fish swim freely in the clear water.More and more people are joining in river protection, making it a common goal to live in harmony (和睦) with these rivers.

四、阅读理解。(★★★,建议用时: 6分钟)
It’s a usual scene in movies and cartoons.A man is walking in a desert, looking for water; when up ahead, he sees a land with water.But there is no land—no water at all, not even a small pool.It was just a mirage (海市蜃楼).
How does a mirage happen The light and air play with our eyes.Normally, light travels in a straight line as a rule, but it can bend and change directions depending on what it passes through.This bending is called “refraction (折射)”.
If different layers (层) of air are at different temperatures, light will bend at different angles (角度) when passing through them.This can create a false image of things around.It does not match the actual object’s shape, position, or appearance in reality.
Mirages can be seen not only over water, but anywhere that can take in a lot of heat, for example, on the hot roads.The next time you think you see a pool of water on the road on a hot summer day, you will know it’s just a mirage—an image of the sky caused by bending light.
The mirage is the magic of nature.When you meet it next time, just take a photo of it and enjoy the beautiful moment.
(  )16.What does the writer use the scene to do in Paragraph 1
A.Share the experience in a desert. B.Describe the brave man.
C.Show when a mirage happens. D.Introduce what a mirage is.

(  )18.What does the underlined word “false” mean in Paragraph 3

A.In a dark room. B.Under a stormy sky.
C.Over a blue ocean. D.In an icy forest.

A.Crazy Animals. B.Modern Art.
C.Amazing Nature. D.Healthy Life.

It is hard to imagine a place that’s more dangerous than Death Valley.Death Valley is the hottest and the driest place in North America.
Death Valley isn’t an easy place to live in.It gets less than two feet of rain a year and it’s hot, too.In July, temperature in this place often reaches over 46℃.There is even a lake that has turned into salt crystals (晶体).But it is cold at night.When it gets cold enough, the water on the ground will turn into very thin ice.Then the strong wind—like a large
hand—can move the rocks along the icy ground.That is why the rocks can “walk” on their own in Death Valley.
Although the weather condition in Death Valley is terrible, it is still filled with lives.Nothing can stop plants and animals from making it their home.People find more than 1,000 kinds of plants there.It also has 51 kinds of mammals (哺乳动物), 6 kinds of fishes, and more than 300 kinds of birds.The animals aren’t all small, either.
Finding water is the biggest challenge for anything that lives here.Some plants have roots that go fifty feet under the ground to find water.Kangaroo rats get the water they need from flowers.Death Valley really creates a lot of surprise!
