The Earth is facing a climate crisis, but it’s also getting greener. According to a new research, the rise is largely because of China and India. A study by NASA, based on extensive satellite imagery, has revealed that the two countries with the world’s biggest populations are also responsible for the largest increase in green plants.

A third of the leaf increase is attributable to China and India, due to major tree planting projects as well as a vast increase in agriculture. “China and India account for one-third of the greening, but contain only 9% of the planet’s land area covered in vegetation (植被)—a surprising finding, considering the large populations in the countries need much land,” Chi Chen, the study’s lead author said in a statement.

Between 2000 and 2017, a NASA sensor gathered data of the Earth’s surface from aboard two satellites, the Terra and the Aqua. Using the data, researchers discovered that China is the source of a quarter of the increase in green leaf area, despite possessing only 6.6% of the world’s vegetated area. Forests account for 42% of that increase, while croplands make up a further 32%. China’s increase in forest area is the result of forest conservation and expansion programs, established to combat the impacts of climate change and air pollution.

Rama Nemani, a researcher at NASA’s Ames Research Center, said in a statement, “When the greening of the Earth was first observed, we thought it was due to a warmer, wetter climate from the added carbon dioxide in the atmosphere, leading to more leaf growth in northern forests, for instance. Now, with the data, we see that humans are also contributing,” Nemani said. “This will help scientists make better predictions about the behavior of different Earth systems, which will help countries make better decisions about how and when to take action.”

1.What’s the text mainly about?

A.The climate crisis the Earth is facing.

B.A solution to global climate warming.

C.Actions taken to fight against air pollution.

D.China and India’s contributions to global greening.

2.Why is the finding considered surprising for China and India?

A.They need much land for agriculture.

B.They are greatly polluted countries.

C.They are rich in natural resources.

D.They both face a serious food crisis.

3.What percentage does China make up of the total green leaf growth?

A.6.6%. B.25%.

C.33%. D.42%.

4.What did Rama Nemani’s want to emphasize?

A.The scientists made a wrong prediction.

B.Climate is a critical factor in leaf growth.

C.Human efforts cannot be ignored.

D.It is never too late to take actions.

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.

Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock. During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.

People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving.

House building becomes a great challenge to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses.

1.What did people begin to consider as electricity was no longer cheap?

A．The climate of their areas

B．The building materials for their houses

C．The fashions for their houses

D．The energy for their houses

2.People in some areas gain a source of heat by _________.

A．keeping their livestock downstairs

B．protecting their livestock from the cold

C．sharing their houses only with their cows

D．living on the second floor with their livestock

3.The underlined words “natural law” in the third paragraph refer to the fact that ________.

A．heat raises the temperature in the houses

B．heat goes in the upward direction

C．heat goes up if temperature is raised

D．heat increases the temperature of rocks

4.From the passage, we can conclude that _______ .

A．people will no longer consider building materials in the future

B．almost all people will move into the houses heated by large rocks

C．energy-saving buildings will become more popular in the future

D．energy engineers will devote themselves only to modern technology

5.What is the main idea of the passage?

A．Energy-saving house building

B．House building is a great challenge

C．How to live in energy-saving houses

D．Energy-saving houses’ bright future

China has entered the cinematic space race. The Wandering Earth, the country’s first blockbuster sci-fi, is on track to be one of the most successful films in China’s history.

Set in the distant future, the governments of the Earth, faced with destruction from an unstable sun, have strapped thrusters (助推器) onto the planet, carrying it out into the universe in search of a new home. But as the Earth approaches the Jupiter, something goes wrong in the system puts it on course to crash into the planet. Therefore, countless people have come forward to face the challenge and save the Earth.

The film is seen by some as the dawn of Chinese sci-fi—a field that has long been dominated by Hollywood.

China is already home to a thriving science and speculative fiction literary scene. The Wandering earth is based on the work of Liu Cixin, the author of the Three-Body Problem series and the first Chinese author to win a Hugo Award, “The Wandering earth fills the gap in Chinese sci-fi movies. It means that China’s sci-fi movies have officially set sail,” one fan of the film wrote on Douban.

China’s film market is expected to overtake the US as the world’s largest by 2022, but there is still a long way to go. The main difference between Chinese and US audience is trust. “Building trust between producers investors and the audience is the biggest challenge here. Not so many people have faith in a Chinese sci-fi movie.” said Liu. the author of the novel.

Some noted that unlike many Chinese blockbusters, The Wandering earth dials back on the patriotism. Rescue teams from around the world scramble to get the thrusters back up and running. A Russian soldier sacrifices his life to help a Chinese colleague.

“This is not a patriotic film but a film about humans saving themselves,” one reviewer said.

1.What does the second paragraph mainly talk about?

A.The plot of the film. B.The influence of the film.

C.The peak of the film. D.The background of the film.

2.Which is the closest in meaning to the word dominated in Paragraph 3?

A.controlled B.challenged

C.abandoned D.affected

3.What is the biggest challenge for Chinese sci-fi films right now?

A.Chinese sci-fi films are poorly produced.

B.There is not enough money to put into sci-fi films.

C.Chinese movie-goers lack faith in home-made sci-fi films.

D.Chinese sci-fi films don’t have a good atmosphere for creation.

4.Why does the author mention a Russian soldier’s sacrifice in the film?

A.To add more vivid and moving details to the film.

B.To compare the film with Chinese traditional films.

C.To arouse the readers’ interest in watching the film.

D.To prove the film’s theme is far beyond patriotism.

5.Which can be the most suitable title for the text?

The Himalayan Mountains are home to the highest peak in Mount Everest. Now the first complete study of this remote region shows that is glaciers (冰川) lost billions of tons of ice from 2000 to 2016.

This is the first comprehensive look at what’s happened to glaciers in the Himalaya over a 40-year time, said lead author Joshua Masurer.

“Our study shows a strong signal of glacier ice loss linked to rising temperatures from climate change,” Maurer says. As much as quarter of the regions ice has been lost, he said, “Temperatures in the region have risen one degree, and one degree was indeed enough to produce such a great loss of glacier ice.”

The signal showing Himalayan ice loss linked to rising temperatures would not be so clear if it weren’t for the U. S satellites that photographed the region. Declassified photos from those satellites were turned into 3-D models to show what the glaciers’ elevations and sizes were in the 1970s, Maurer said. Those were then compared to more recent complex NASA satellite photos that shows changing elevations of the ice over time.

The ice and snow in the region are the source for Asia’s great rivers. The study did not include the huge neighbouring ranges of high mountains, but other studies suggest that similar melting is under way there as well.

This melting means flooding and the creation of many glacial lakes. In May 2012, one such flood killed over 60 people in villages near Pokhara, Nepal; it also destroyed houses. Some 800 million people depend in part on rivers from Himalayan glaciers for irrigation, making electricity, and drinking water. The more rapid melting appears to increase the river water during warm seasons, but scientists say that will decrease within decades as the glaciers lose mass.

1.Why did the glaciers in the Himalayan Mountains lose much ice?

A.Many people used the ice to make electricity.

B.The climate change increased the temperature.

C.America used satellite to increase one degree Celsius.

D.The flooding and many glacial lakes took much ice away.

2.How did the scientists get the conclusion?

A.By making an interview.

B.By studying the finding of other scientists.

C.By collecting information by means of satellites.

D.By comparing the data collected by U. S. satellites.

3.What can we infer from Paragraph 5?

A.Only the glaciers in Himalayan Mountains lose ice.

B.Many great rivers run to the Himalayan Mountains.

C.Many Asian regions face the problem of ice loss.

D.The melting of ice is nothing serious.

4.What is the purpose of giving the example in the last paragraph?

A.To show the risk of living near mountains.

B.To show the risky consequence of the ice loss.

C.To ask people to take action to use glaciers.

D.To predict the future of the Himalayan Mountains.
