Deep under the Pacific Ocean lie coral reefs(珊瑚礁) coloured by some algae(海藻) that live with corals. Corals usually provide nitrogen(氮) for algae，and in return they get carbon(碳)，which gives them energy.
In the early 1980s，a huge heat wave turned more than 90 percent of these corals a pale，lifeless white. And it was believed that about 50 percent of reefs with beautiful corals might disappear by 2030. Heat waves warmed up the same Pacific waters in the late 1990s and again in 2015 and 2016，but scientists noticed that these heat waves didn't influence the reefs as badly as the first. Maybe corals have found a way to adapt(适应).
Swimming to cooler waters is not a good choice for corals，for it makes them easily hurt by the changing climate. But corals are able to adapt. Some turn to those algae that can deal well with heat. Others can use rows of tiny hairs on their bodies to "fan" away too much harmful oxygen (O₂) let out by stressed-out algae. Certain baby corals change their own metabolisms(新陈代谢) in order to fight the warming waters. But all these adaptations can protect themselves only to some degree.
After studying and understanding these adaptations，scientists are trying to find ways to help corals fight. If researchers can make corals accept algae that can deal with heat pressure or if they energize genes(基因) that can deal with heat pressure，it will raise the corals' chance of living through future ocean heat waves.
"When I go down to the sea and see a beautiful healthy reef with these colourful corals，I feel this pleasure of being in this underwater world，" a famous biologist says. "It will be really sad to see it dead. But that does drive you to want to use your skills and your love to help fight."
29. What can we know from Paragraph 1?
A. Corals make algae more colourful.
B. Algae provide room for corals to live in.

A. The heat wave in the early 1980s.
B. The heat wave in the late 1990s.
C. The Pacific waters in 2015 and 2016.
D. The reefs' disappearance by 2030.
31. What can we infer from the last paragraph?
A. It's necessary to live with corals.
B. The ocean has become unhealthy.
C. We should try our best to save corals.
D. Making a study of the ocean is a must.
32. Which would be the best title for the text?

C. Corals break down
D. Corals come into being

Have you ever wondered what else you can do on the train besides sleeping or scrolling through your phone? Actually in China，trains have turned into centres which bring together the public and the nation's intangible cultural heritage (ICH).
Trains go across China and they are becoming ideal places for introducing local traditional culture. A good example is the K7041 train from Harbin to Mohe in North-east China's Heilongjiang Province. On the ICH train，Gulayier，dressed in traditional clothes，sang Oroqen folk songs and his partner played the Oroqen jaw harp，a musical instrument. Tourists on the train，especially those from southern China，sang and danced excitedly with the two performers(表演者) together. Gulayier said the train made it easier to hold tourists' attention to his shows. He thought the train was a good platform for promoting(促进) ICH.
Traditional heritage comes to life on trains. More ICH such as Qinhuai lanterns from Nanjing，Yulin puppet shows，and tea-picking operas in Guangxi has also made appearances on high-speed trains across China. It offers passengers a close-up way to experience traditional culture.
Professor Xiao Fang from Beijing Normal University shares Gulayier's opinion on the new use of ICH trains. He has pointed out another advantage of this. Beyond cultural promotion，it also helps tourism. When passengers enjoy local traditions on board，they often develop a deeper interest in exploring the places they pass through.
However，the ICH train journeys still have challenges，including the narrow space on trains and passengers getting on and off at each station. Therefore，some solutions are coming up—cultural corners show traditional arts，and QR codes connect more digital information. Those help passengers to explore ICH at their own pace and continue learning after their journey ends.
The success of ICH trains provides valuable lessons for cultural protection worldwide，proving that innovation and tradition can work together to keep cultural heritage alive for future generations.
33. What is the fresh experience for passengers on the K7041 train?
A. Travelling farther north.
B. Joining in live shows.
C. Wearing traditional clothes.
D. Having fun on the phone.
34. What do Gulayier and Professor Xiao agree?
A. ICH encourages more local visits.
B. Trains help make ICH more popular.
C. ICH improves the Chinese train journeys.
D. Passengers welcome performers on ICH trains.
35. What does Paragraph 5 mention about the ICH train journeys?
A. Their features and influence.
B. Their reasons and results.
C. Their problems and methods.
D. Their future and improvement.
36. What can be the best title for the passage?
A. Trains push China's cultural heritage further
B. China puts arms around local artists on ICH trains
C. More ICH trains begin running on railways in China
D. Train passengers share different local cultures of China
