The terrible E1Niño strikes the globe every 2 to 7 years. As warm waters in the tropical(热带的) Pacific Ocean switch eastward and trade winds weaken the weather pattern stretches through the atmosphere, causing drought in southern Africa, wildfires in South America, and flooding on North America's Pacific coast. Climate scientists have struggled to predict El Niño events more than 1 year in advance, but artificial intelligence (AI) can now extend the latest forecasts to 18 months, according to a new study.
The new research uses a type of AI called a convolutional neural network(卷积神经网络), which is adept in recognizing images. Researchers feed the neural network a large number of training images and the AI becomes skilled at identifying fundamental patterns of those images. For example, the neural network can be trained to recognize cats in photos by identifying characteristics shared by all cats, such as hairs and four legs.
Part of the problem with earlier researches on El Niño forecasts is that they rely on a relatively small set of historical statistics for factors such as ocean temperature. To get around this shortage, the scientists fed the program re-creations of historic ocean conditions produced by a set of reliable climate models, ones frequently used for studies of climate change, says the study’s lead author, Yoo-Geun Ham, a climate scientist in South Korea. As a result, the scientists could show the computer system not just one set of actual historic data, lasting from 1871 to 1973, but several thousand reproductions of that same data by the climate models.
But it’s not clear how much real-world benefit will come from pushing forecasts beyond 1 year, cautions Stephen Zebiak, a climate scientist at Columbia University, “The kind of lead time that is actionable is probably less than a year because decision-makers are unlikely to take action further in advance,” he says.
1.What is the advantage of the latest AI forecasts?
A.Faster response. B.Higher accuracy
C.Wider application. D.Longer time range.
2.What does the underlined word “adept” probably mean?
A.Carefully-chosen. B.Well-trained.
C.Newly-developed. D.Wide-spread.
3.What is paragraph 3 mainly about?
A.Improvement on previous studies. B.Requirements for weather forecast.
C.Procedure for analyzing image data. D.Problems with early climate models.
4.What does Stephen Zebiak think of the new AI prediction?
A.It has unclear impacts. B.It calls for effective action.
C.It may not be of actual help. D.It should be treated with caution.

According to the US Geological Survey, about seven million earthquakes strike worldwide every year—but fortunately, only about 1500 of these are of a magnitude(震级) of 5 or greater on the Richter scale. Certain areas, such as California and Japan, are more prone to earthquakes than others. Although the chance of being caught in “The Big one” is remote, it’s wise to be prepared if you live in a region where earthquakes are common.
Educate your family about earthquakes before a big one strikes. For example, they need to know to take shelter in a doorway or under a strong object if indoors, and never to run outdoors if they are inside. If outside, they need to know to stay away from power lines and buildings where objects could fall.
Teach family members how to turn off gas or water lines or electrical power that may need to be shut off after a quake if severe damage occurs.
Develop a plan. Where will your family meet in the event of a disaster? What if some people are at work or school? How will you know if they are safe? Where will you all meet up?
Pack a preparedness kit(衣物装备) and keep it in a safe location. In a major earthquake, it’s possible that you won’t be able to get into your house. Keep supplies in your car trunk or an outside storage shed if possible. Pack whatever your family is likely to need, enough for three days to a week, including food, water, medication, first aid and personal hygiene supplies, flashlights, a portable radio, blankets, clothes and shoes, cash, or camp stove, candles, matches or lighters, and a whistle.
Consider earthquake insurance for your home if you live in an earthquake-prone area. Regular homeowner’s insurance doesn’t cover earthquake damage.
1.The underlined words “prone to ” in paragraph 1 can be replaced by___________.
A. likely to suffer B. frequent to explore
C. regular to measure D. impossible to experience
2.According to the passage, if you are outside in an earthquake, you should_________.
A. stay where you are B. hide under a big tree
C. avoid power lines D. sit on the ground
3. We can learn from the passage that_________.
A. about 1,500 earthquakes happen every year
B. people should store some clothes in their houses in advance
C. family members should meet in their home after an earthquake
D. people suffering earthquakes often should buy earthquake insurance
4.What would be the best title for the passage?
A. How to Keep Safe in an Earthquake
B. How to Prepare for an Earthquake
C. Who Can Help Us After an Earthquake?
D. Where Is an Earthquake-prone Area?

Every year from March to October, Christian Moullec, also known as “Birdman,” takes to the skies aboard his adapted light aircraft. However, the 58-year-old Frenchman’s daily 30-minute flight is not just to enjoy the impressive views, but to guide flocks (鸟群) of lesser white-fronted geese (小白额雁) through safe migration paths which the birds can teach future generations.
His deed began in 1995 when he noticed their declining population in the wilds of Lapland, Sweden. To prevent their numbers from dropping further, Moullec tried to get the threatened species to follow him along migration routes that would protect them from bird hunters.
However, getting grown geese to follow his lead proved challenging. As young geese imitate and follow whomever they view as their parent, Moullec decided to raise the geese from birth.
To help raise funds and awareness of his job to protect not just the geese but birds worldwide, Moullec often allows paying tourists to join him on the 30-minute-long flights aboard his aircraft. In addition to the trained birds flying alongside them, visitors, who come from as far as a 15-hour plane flight away, are treated to a variety of crane and geese species as well as breathtaking views of castles and cities.
He often brings his camera along for the flights, capturing photos not just for their beauty, but for what they describe. Moullec believes the use of agricultural chemicals has done harm to wild European birds, with more than a third disappearing in the last 30 years. “It's a disaster,” he said. “My beautiful images with flying birds should be used to tell this story. ”
1.Why does “Birdman” always fly to the sky on his aircraft?
A.To observe geese along their migration routes.
B.To follow geese through safe migration paths.
C.To take visitors to operate his adapted aircraft.
D.To guide geese fly safely during the migration.
2.What do we know about “Birdman”?
A.He is a nature lover. B.He is a bird watcher.
C.He is a volunteer pilot. D.He is a bird hunter.
3.What does Moullec often take photos in his flights for?
A.Recording the use of agricultural chemicals.
B.Showing serious damage caused by chemicals.
C.Describing his experiences with flying birds.
D.Capturing the beautiful views of birds and cities.
4.What can be a suitable title for the text?
A.Birdman Guides Flocks to Learn to Fly.
B.Birdman Finds Birds Disappearing.
C.Birdman Helps Flocks Safely Migrate.
D.Birdman Protects Birds From Hunters.

Cancer is a terrible disease. Every year in the UK, more than 330,000 people get cancer, and doctors usually use a kind of therapy called radiotherapy to treat people. This treatment uses high energy X-rays to destroy the disease, but the effects of treatment can be nearly as bad as the cancer. As the X-rays destroy the cancer cells, they also damage healthy cells that are next to them. It’s like using a shotgun to kill an insect. When really important parts of a person’s body are hurt by the X-ray energy, it can have very bad results. It can also make more cancer grow in the damaged places in the future.
A new therapy that uses protons(质子) instead of X-ray energy could be the answer to the problem. In a project called PRaVDA, scientists from the UK and South Africa are working to this. If X-ray energy is like a shotgun, then protons can work more like a laser. Scientists can make protons travel through someone’s body without hurting them, and only damage the cancer.
The PRaVDA scientists use computers to make a 3-D model of the cancer cells to make sure the protons go to the right places. “It’s more accurate,” said Michaela Esposito, PhD, from the University of Lincoln.
Building this technology was very difficult, though. Professor Nigel Allinson from the University of Lincoln, the project leader, has put together a team of many different kinds of scientists with different skills. Those skills were all needed to make what he calls “one of the most complex” medical machines ever. It’s also 10 times more expensive than X-ray radiotherapy. Even so, Allinson believes that most cancer treatment will be done by protons in the future. “I think it will improve the quality of life of many cancer patients,” he says.
1.What point does the first paragraph make?
A. Cancer is a really terrible disease.
B. Lots of people get cancer every year in the UK.
C. Radiotherapy isn’t a perfect way to cure cancer.
D. Radiotherapy is a commonly used therapy against cancer.
2.What can be concluded about the new therapy?
A. It’s much cheaper than X-ray radiotherapy.
B. It depends on protons to locate the cancer cells.
C. Damaging the cancer by replacing X-rays with lasers is much more accurate.
D. It uses protons to damage the cancer cells without damaging healthy cells.
3.According to Professor Allinson, the new therapy ________.
A. will enable cancer patients to enjoy a better life
B. will cure most cancers in the future
C. will ensure that cancer patients live longer
D. will replace radiotherapy completely
4.What can be inferred from the text?
A. Science and technology are a double-edged sword.
B. Not every cancer patient will be able to afford proton therapy.
C. Radiotherapy is completely the wrong way to cure cancer.
D. The complex medical machine mentioned will soon be put into use.

Do people travel to the other side of the globe until a one-year-old baby? Is it a smart idea? I wonder if I was crazy. I had various adventures—hut this trip would be different. This South American adventure would be a unique life experience of mine. I had given up many activities in order to please a little person, because Anders’ needs had to come first. At 30 years old, it was a difficult change for me, and I was occasionally annoyed when I realized that my son had taken away so many things from me.
Argentina is a long way from my home. It was even longer when I was on the plane and sharing a seal with such an active little boy, but Anders and I made it without angering any other passengers or getting any dirty looks. And we look a rest on a regular schedule.
I wanted to do some hikes in Argentina and drive ten hours to the coast to see penguins. However, when I thought about my travel partner, I gave up these ideas. Instead, we just hung out by lakes, picking up stones and throwing them in the water. I took short hikes, running with Anders in die backpack, knowing that I had two hours before his tolerance gave out and the complaining started.
I discovered that traveling with a baby opens new doors that aren’t there for a solo traveler or couple. Anders helped me to slow down and look at the landscape closely. I got to see Argentina through someone else’s eyes. The traveling wasn’t as fast-paced as it would have been if I had been alone, but the details were amazing. Now I just have to absorb that insight into our life back home.

A. Her baby didn’t like them.
B. Her baby’s tolerance gave out.
C. She desired more interesting activities.
D. She wanted to have her baby share the activities.
