26、Scientists are using robots to study the health of waters in and around Venice，Italy．The robots are designed to act like fish，other underwater creatures and plants．The scientists are working with several universities and research centers as part of a group called subCULTron．The European Union gives money to the project as part of its Horizon 2020 program whose aim is to take great ideas from the lab to the market and support science and innovation(创新)in Europe．The scientists want to use the artificial intelligence of the robots to help humans understand what is happening under the water of the Venice lagoon(潟湖)．
SubCULTron．a collective artificial intelligence project，plans to create the biggest shoal (鱼群)of robot fish in the world．The project’s aim is to improve knowledge of the seabed and try to turn human abilities into hi-tech items．
Alexandre Campo，a computer scientist，says the scientists have looked at the way animals learn to work in groups to understand how robots can learn to work together．The subCULTron project wants its robots to learn to work together so they can watch out for changes and new problems in the water．
One problem the researchers had in the beginning was how the robots would communicate with each other. Wi-Fi and GPS equipment don’t work underwater．Instead，the robots can use sonar(声呐)and an electric field．
Another problem was charging batteries．The robots come up to the water’s surface and stay near a boat or a power station to charge without any electrical cables．Besides，how to be waterproof, especially for some key pads of the robots，was really tough．Fortunately, a special mixture has been created to be pinned on the robot，which successfully stands the test of water．
The health state of the lagoon is pretty good．There are no industrial polluters，and the city now has a modern sewer(污水管) system．It’s not like before when all the waste flushed directly into the water．The robots in Venice will continue their work until 2019. The subCULTron project hopes they develop into “an artificial society underneath the water surface” that serves “a human society above the water”．
【1】What can we learn about the project in Paragraph l?
A. Its researchers are all from universities．
B. The European Union has financially supported it．
C. It uses robots to clean the waters in and around Venice．
D. It is aimed to support science and innovation worldwide．
【2】What can we infer according to Alexandre Campo?
A. Scientists have got an idea for robots from the animals．
B. The robots are working separately to perform their tasks．
C. SubCULTron is to turn human abilities into hi-tech items．
D. The health state of the lagoon has greatly improved recently．
【3】The underlined word “they” in the last paragraph probably refers to“__________”．
A. scientists B. animals
C. robots D. humans
27、Microplastic pollution has been detected in human blood for the first time, with scientists finding the tiny particles(微粒) in almost 80% of the people tested.
The discovery shows the particles can travel around the body and may live in organs.The impact on health is as yet unknown. But researchers are concerned as microplastics cause damage to human cells in the laboratory and air pollution particles are already known to enter the body and cause millions of early deaths a year.
Huge amounts of plastic waste are left in the environment and microplastics now pollute the entire planet, from the top of Mount Everest to the deepest oceans. People were already known to consume the tiny particles via food and water as well as breathing them in, and they have been found in the faeces (排泄物) of babies and adults.
The scientists analysed blood samples from 22 healthy adults and found plastic particles in 17. Half the samples contained PET plastic, which is commonly used in drinks bottles, while a third contained polystyrene, used for packaging food and other products. A quarter of the blood samples contained polyethylene, from which plastic carrier bags are made.
“Our study is the first indication that we have polymer particles(聚合物颗粒) in our blood — it's a breakthrough result,” said Prof Dick Vethaak, an expert at Vrije Universiteit Amsterdam in the Netherlands. “But we have to extend the research and increase the sample sizes, the number of polymers assessed, etc.” Further studies by a number of groups are already under way, he said.
“It is certainly reasonable to be concerned,” Vethaak said. “The particles are there and are transported throughout the body.”He said previous work had shown that microplastics were 10 times higher in the faeces of babies compared with adults and that babies fed with plastic bottles are taking millions of microplastic particles a day.
Vethaak acknowledged that the amount and type of plastic varied considerably between the blood samples. “But this is a pioneering study,”he said, with more work now needed. He said the differences might reflect short-term exposure before the blood samples were taken, such as drinking from a plastic-lined coffee cup, or wearing a plastic face mask. "
The big question is what is happening in our body?" Vethaak said. “Are the particles retained in the body? Are they transported to certain organs, such as getting past the blood-brain barrier? And are these levels sufficiently high to cause disease? We urgently need to fund further research so we can find out. ”
【1】What could be inferred from Paragraph 2?
A．Air Pollution particles can cause death eventually.
B．Microplastics can be deadly to humans.
C．There is no evidence that microplastics harm human cells.
D．Microplastics can travel throughout body and damage organs.
【2】What can we learn about microplastics from Paragraph 4?
A．They are found in most people.
B．Polyethylene found in blood samples might be taken from drinks bottles.
C．A quarter of the blood samples contained PET particles.
D．Half of the microplastics in the blood samples were likely introduced by drinking from plastic containers.
【3】The underlined part “this is a pioneering study”in Paragraph 7 probably means______ .
A．we are the pioneers in the field of plastic research
B．we need more blood examples
C．we are entering a whole new field of research
D．this is an extremely important study
【4】Which section of the newspaper may this article be found in?

28、Last September, British artist Sacha Jafri set the record for creating the world's largest painting. Last week, the painting was sold for $62 million, which will go to charity.
Last year, as the COVID-19 spread and many countries went into lockdown, Mr. Jafri was in Dubai. Rather than feeling stuck, Mr. Jafri decided to take on a huge project that could“make a really big difference”.
He decided to create the world's largest painting. And he wanted to do it in a way that would include people from around the world. He asked children to send him pictures showing how they were feeling during the pandemic(疫情). He got artwork from kids in 140 different countries.
Using the children's ideas as a starting point, Mr. Jafri began to paint in a huge dancing room in a fancy hotel. It took Mr. Jafri seven months to create the painting. He worked long hours every day—often up to 20 hours a day. He hurt his back by bending over so much while he painted. It took over 1,000 paintbrushes and 6,300 liters of paint to create the painting. The painting, which was over 1,600 square meters, was around the size of four basketball courts.
Mr. Jafri hoped that his painting, called “The Journey of Humanity”, would help bring the world together during a difficult time. Since Mr. Jafri’s goal was to raise money to help children suffering from the pandemic, the painting was split up into 70 large parts. Mr. Jafri hoped that by selling the parts separately, he could raise $30 million.
But when the auction(拍卖) ended on March 22, Mr. Jafri did much better than that. A French businessman bought all the pieces. Knowing that the money would go to charity also motivated him to decide to pay more. He says he was poor when he grew up, so he's glad to be helping children around the world by buying the painting.

【2】What can we know about the large painting?
A．It remained complete all the time.
B．It took the artist a lot of efforts.
C．It earned the artist a better living.
D．It was made to set a world record.
【3】Why did Sacha Jafri create the painting?
A．To help fight the pandemic.
B．To develop kid’s love for art.
C．To show pandemic sufferings.
D．To kill time and seek pleasure.
【4】Which of the following words can describe the French businessman?
A．Modest and honest.
B．Brave and determined.
C．Sympathetic and generous.
D．Creative and hardworking,
29、A retired United States soldier named Terry McGlade, who had served in Iraq and Afghanistan, says his dog Major is a hero. He is specially trained to sense when McGlade is about to have a seizure (突然发作), get his phone and dial 911 for help.
When Major had recently sensed an incident about to happen, and McGlade collapsed and hit the floor, Major was able to get to McGlade’s phone, and more or less bite on the phone which is specially set up so that when multiple buttons are pressed and held in, it goes into emergency call mode (模式), and dials 911.
“He was actually able to get my phone out of my pocket,” McGlade said.
The 911 operators who got the call from Major said they never heard him bark or anything. However, they could hear what sounded like a confused man in the background, and did get quite doubtful after quite a few calls from McGlade’s cell phone kept coming in. Quite clearly, Major was using his leg and also stepping on the screen to get the phone to dial for help.
After Major was sure someone would be on their way to help, he then made his way out to the front of the house to wait. When the police and ambulance arrived, he led them into the house and right to McGlade, still in danger.
“I probably would have been in severe trouble if he hadn’t called,” McGlade said.
McGlade was taken to the hospital, where he was kept overnight for observation, but thanks to his best friend, and now hero of the day, Major. He is feeling much better, and will make a full recovery with little risk of lasting damage from this particular incident.
【1】What does the underlined word “collapsed” in paragraph 2 probably mean?

31、Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.
Here is a lesson that we’re going to be taught again and again in the coming years: Most animals are not just animals. They’re also 【1】 of microbes (微生物). If you really want to understand the animal, you also have to understand the world of microbes inside them. In other words, zoology is ecology.
Consider the western corn rootworm---- a beetle that’s a serious pest of corn in the US. The adults have strong preferences for laying eggs in corn fields, so that their underground larvae (幼虫) hatch into a 【2】 of corn roots. This life cycle depends on a continuous year-on-year supply of corn. Farmers can use this dependency against the rootworm, by planting soybean and corn in alternate years. These rotations (轮流) mean that rootworms lay eggs into corn fields but their larvae hatch among soybean, and die.
But the rootworms have 【3】 to this strategy by reducing their strong 【4】 for laying eggs in corn. These “rotation-resistant” females might lay among soybean fields, so their larvae hatch into a crop of corn.
There are almost certainly genetic differences that separate the rotation-resistant rootworms from their normal 【5】. Researchers at the University of Illinois began to study the genes of the bacteria in its gut (肠) and found some answers, after focusing on the rootworm’s own genes and found that the results were mostly inconclusive.
“The bad guy in the story----the western corn rootworm---was actually part of a multi-species plot,” says Joe Spencer, who was part of the study. “No wonder it was hard to figure out what was happening. We were only looking at the most obvious 【6】 of the story.”
If you really want to understand the animal, you also have to understand the microbes. The rootworm’s gut bacteria are effectively another one of its organs, but an 【7】 flexible on that can change dramatically when 【8】 to a new food source. This allows the insects to adapt very quickly to environmental challenges, far more quickly than if they could only rely on mutations (突变) in their own genes.
Spencer says, “Modern agriculture has always underestimated the ability of pests to avoid pest control, and I think the 【9】 that pest insects are not alone in their efforts should give us some 【10】. There is a brand new tiny world out there inside every creature, and we need to start thinking seriously about it.”
