Record fires sweeping across the Amazon this month have been grabbing global headlines as scientists and environmental groups are worried that they will aggravate climate change crisis and threaten biodiversity (生物多样性).
As the largest rainforest in the world, the Amazon is often called "the lungs of the world". It is also home to about 3 million species of plants and animals, and 1 million local people. The vast rainforest plays an important role in the world's ecosystem because they absorb heat instead of it being reflected back into the atmosphere. They also store carbon dioxide and produce oxygen, ensuring that less carbon is released, mitigating the effects of climate change.
"Any forest destroyed is a threat to biodiversity and the people who use that biodiversity," Thomas Lovejoy, an ecologist at George Mason University told National Geographic. "The overwhelming threat is that a lot of carbon goes into the atmosphere," he stressed. "In the midst of the global climate crisis, we cannot afford more damage to a major source of oxygen and biodiversity. The Amazon mu:st be protected/5 U.N. Secretary General Antonio Guterres said.
Data from the National Institute for Space Research (INPE) show that the number of forest fires in Brazil quickly increased by 82 percent from January to August this year from a year ago. A total of 71,497 forest fires were registered in the country in the first eight months of 2019, up from 39,194 in the same period in 2018, INPE said. "We estimate that the forest areas in the Brazilian Amazon have decreased something between 20 and 30 percent compared to the last 12 months," Carlos Nobre, a researcher at the University of Sao Paulo, told German broadcaster Deutsche Welle.
Brazil owns about 60 percent of the Amazon rainforest, whose degradation could have severe consequences for global climate and rainfall. The extent of the area ruined by fires has yet to be determined, but the emergency has transcended (超出)Brazil's borders, reaching Peruvian, Paraguayan and Bolivian regions.
1.Which of the following best explains "mitigating” underlined in Paragraph 2?
A.Worsening. B.Causing. C.Easing. D.Benefiting.
2.What can we learn from Thomas's and Antonio's words?
A.The biodiversity makes the rainforest unique.
B.The rainforest fires result in serious consequences.
C.The global climate crisis brings more rainforest fires.
D.The dry weather leads to the rainforest fires.
3.Why does the author list the numbers in Paragraph 4?
A.To present the reduction of rainforest areas.
B.To show the influence of forest fires.
C.To explain the process of the research.
D.To prove the importance of rainforest.
4.Which section of a magazine is this text probably taken from?
A.Sports and music. B.Science and technology.
C..Business and culture. D.Nature and geography.

The Notre Dame (巴黎圣母院) fire has been put out, but its wooden roof have been largely damaged. The terrible accident causes a sudden sharp pain to people around the world, “What a pity that we cannot see the damaged parts of the wonder anymore.”
But the good news is that there is at least one way of seeing them, namely via a video game called Assassin's Creed: Unity. In this game, the player can travel to one city after another and enter the buildings exactly like what they are in reality, and see Notre Dame as it was before the fire. In addition, with VR technology, which is already quite mature, one can even look around the undamaged Notre Dame as if it is still there. Maybe digital technology could help to better protect architectural cultural heritage.
The idea of digitizing ancient buildings, making digital models of them so their data can be saved, dates back to the 1990s and the necessary technology has continued to advance since then. By scanning the ancient buildings with lasers, building 3D models with hundreds of images, as well as measuring everything precisely, engineers can make a copy as “same” as the real one.
As computers and smartphones are hugely popular，the digital replica or digital copy has great pratical value. First, it allows tourists to feel the cultural relics without touching them, which helps protect them. The virtual tour of Dunhuang Grottoes in Gansu Province is a good example of this as tourists can view the paintings without standing near them. Furthermore, it can make the digitized cultural relics more famous by spreading awareness about them via the Internet. In 2000, a virtual tour of the Great Wall became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting it in the following years. Above all, it preserves all the information of the cultural relics. Even if the original ones are damaged one day, people can still know what they were like and can build a replica if desired.
Time is the biggest problem to architectural heritage. Maybe we will have better technologies in the future，but the digital technology offers a practical way to preserve architectural cultural heritage at the moment.
1.Which of the following statement is true?
A.The big fire has damaged the whole Notre Dame.
B.Only people in Paris felt pain for losing Notre Dame.
C.The damaged parts of Notre Dame have already been repaired.
D.A video game can help people see the original look of Notre Dame.
2.What will engineers do to create a digital replica of the ancient buildings?
A.Scan the photos of the buildings B.Build 3D models of full size.
C.Improve the technology needed. D.Measure all the parts exactly.
3.How does the author prove the digital copy has vital practical importance?
A.By comparison. B.By listing data.
C.By giving examples. D.By classification.
4.What is the best title of the passage?
A.The Damage of Notre Dame
B.The Value of Digital Replica
C.VR Technology Helps Repair the Cultural Relics
D.Digital Technology Helps Protect Ancient Buildings

Across the United States, universities and colleges have been looking to become more sustainable (可持续发展的) and more than 600 schools have already planned to become eco-friendly. The EcoDorm, home to 36 students at Warren Wilson College in Swannanoa, was designed to be sustainable from top to bottom, or in this case, from its rainwater-collection system to its garden. The dormitory is bringing new meaning to the concept of living “green” at college.
At Warren Wilson College, a biological science school with fewer than 1,000 students, the sustainability drive came from the student body. The EcoDorm concept was presented ten years ago by two students; a planning committee firstly suggested using building materials like corncob. Although the architects disagreed with the idea, they came up with other creative solutions: Wood siding was taken from the trees grown in the school yard that were suffering from a disease, and rainwater was collected in an old railway car and pumped back into the house to clean the toilets.
All in all, the dorm uses nearly two-thirds less electricity than a similar-sized traditional building would. But even the most sustainable homes need continued efforts from its livers. And in the case of EcoDorm, students live by their words. Most also take advantage of the dorm’s bio-garden, planting and harvesting fruits and vegetables. “I didn’t have to worry about paper towels being wasted or feel bad about drying my clothes outside,” Jeremy Lekich, the dorm’s gardener, said. “Basically, it has made my life easier.”
1. We can learn from the text that the EcoDorm in the US .
A. offers students the chances to have a natural living at college
B. was firstly built by two college students
C. was designed for saving building materials
D. is only applicable in few schools
2. The second paragraph is mainly about .
A. where the EcoDorm was built
B. when the EcoDorm got its name
C. what the EcoDorm is made of
D. how the concept of EcoDorm started
3. What can be inferred from the text?
A. A long-term development calls for students’ efforts.
B. Students’ ideas should be encouraged at college.
C. Green living is a new trend at American colleges.
D. Students can learn to protect the environment through practice.
