1 . Experts are warning about the risks of extremely picky(挑剔的)eating after a teenager living on a diet of chips and crisps developed lasting sight loss. Eye doctors in Bristol cared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”
The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to the Bristol Eye Hospital because of progressive sight loss.
He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it really arduous to read, watch TV or recognize faces.”
Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too many certain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”

2 . New parents who clean their homes very often to protect their babies from bacteria and other organisms might cut back their efforts.
A new study suggests high levels of contact with cleaning products are linked to an increased risk of the childhood breathing condition known as asthma (气喘).
Researchers asked a group of parents how often they used 26 common household cleaners during their babies’ first three to four months of life. By age three, the children who had come in contact with cleaning products the most were more likely to be diagnosed with asthma. The researchers said children who had a lot of contact with cleaners were 37 percent more likely to have asthma than children with the least contact. The study also found a lot of exposure to cleaning products caused children to be 35 percent more likely to have chronic difficulty breathing. In addition, they were 49 percent more likely to have chronic allergies.
Tim Takaro, who helped lead the study, suggested that parents should question the belief that their home is clean only if it smells like chemical-based cleaning products. He also advised them to look for products free of substances like chemical colors. Besides, they should consider natural cleaning products instead of chemical ones.
The American lung Association recommends avoiding cleaning products that contain volatile (易挥发的) organic substances and other irritants (刺激物). But companies in Canada and the United States are not required to list all the chemicals in cleaning products. Some products labeled as environmentally friendly, or "green", may contain harmful substances.
Elissa Abrams, a doctor with the University of Manitoba, admitted the effects of cleaning products are not well understood. But she believed these products and the chemicals they contain act as irritants to growing children "The take-home message is that parents should be careful with cleaning products they use in the home", she added.

3 . My work started in 2003 at my local animal shelter’s Adoption Department. It seems like such a long time ago. In the 13 years that have passed, more than 50,000 animals have passed the doors of the shelter. Most of them, I do not remember. But occasionally there are animals who stand out. Tabby was one such animal.
Tabby was one of the many homeless dogs. What’s more, she was blind and deaf. Tabby’s chances at adoption seemed remote at best. But one day a woman named Loretta came to the shelter. Her son, Gary, who suffered from epilepsy (癫痫) had seen Tabby’s picture on the shelter’s website. They were interested in meeting her! Most boys would want a puppy, a dog who could grow with him and run through grassy fields on summer days. Tabby would never be able to do that. But as they say, "love is blind". After meeting her, they decided to adopt Tabby!
If Tabby’s story had simply ended with her successful adoption, it would still have been something very special indeed but it was what happened after her adoption that some might label as "magical" or perhaps even miraculous. As Gary and Tabby did everything together, they became so "in tune" with one another that Tabby began to telegraph Gary’s seizures (疾病发作) before they occurred, giving his family a warning that one was about to strike. What’s more, Gary seemed to be having fewer and fewer seizures since Tabby’s arrival.
How could it be? There are some things that happen in this world that challenge all logic and understanding. Sometimes, the best that we can do is to accept a miraculous thing, which we didn’t attempt to explain. Because when you try to explain it, you lose the beauty and wonder of it all.

| A．Amazing. | B．Typical. | C．Interesting. | D．Special. |
| A．Gary learnt about Tabby from a magazine. |
| B．Gary was cured in the company of Tabby. |
| C．Tabby could indicate a seizure before it struck. |
| D．Most boys would have the same decision as Gary. |
| A．Love is Blind: a Miraculous Dog | B．Give Me Food: My Dear Master |
| C．Love is Everywhere: a Poor Dog | D．Take Me Home: My Dear Boy |
4 . An 85-year-old primary school constructed in 1935 in Shanghai has been lifted off the ground in its entirety and relocated using new technology called the “walking machine.” The project marks the first time this “walking machine” method has been used in Shanghai to relocate a historical building.
Urbanization（都市化）has continued to significantly threaten architectural heritage. In the capital Beijing, for instance, more than 1,000 acres of its historic hutongs and traditional courtyard homes were destroyed between 1990 and 2010.
In the early 2000s, cities including Nanjing and Bejjing-due to the critics’ protest about the loss of old neighborhoods-drew up long-term plans to preserve what was left of their historic sites, with protections introduced to safeguard buildings and restrict developers.
These conservation efforts have taken different forms. In Beijing, a near-ruined temple was transformed into a restaurant and gallery, while in Nanjing, a cinema from the 1930s was restored to its original form, with some additions providing it for modern use. In 2019, Shanghai welcomed Tank Shanghai, an arts center built in renovated（重修的）oil tanks.
“Relocation is not the first choice, but better than destroying,” said Lan, the Shanghai primary school’s project supervisor. “I’d rather not touch the historical buildings at all.” Building relocations he said however, are “a workable option.” “The central government is putting more emphasis on the protection of historical buildings. I’m happy to see that progress in recent years.”
Shanghai has arguably been China’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings and 19th-century “shikumen” （or “stone gate”） house have offered examples of how to give old buildings new life.
“We have to preserve the historical building no matter what, ” Lan said. “The relocation has challenges, but in general, it is cheaper than destroying and then rebuilding something in a new location.”

| C．Old Building Torn down for Modern Use | D．Historical Site “Walks” to New Life |
5 . If you're daydreaming of future travels while stuck at home during the Covid-19 outbreak, why fantasize about the beaches of Ball or the canals of Venice when vacationing in space could be in your future?
Back in 2019, Californian company the Gateway Foundation released plans for a hotel that could one day float above the Earth's atmosphere. This futuristic concept was scheduled to be fully operational by 2027.
Now the hotel, Voyager Station, is set to be built by Orbital Assembly Corporation, a new construction company run by former pilot John Blincow, who also heads up the Gateway Foundation.
In a recent interview, Blincow explained there had been some Covid-related delays, but construction on the space hotel is expected to begin in 2026, and a hotel in space could be a reality by 2027.
"We're trying to make the public realize that this golden age of space travel is just around the corner. It's coming. It's coming fast," said Blincow.
Space tourism is becoming an increasingly hot topic, and there are several companies trying to make it happen — from Virgin Galactic to Elon Musk's SpaceX.
The team behind Voyager Station have said they're hoping to eventually make a stay at the hotel equal to "a trip to Disneyland ".
The team are also hoping to build research stations and spark space tourism and commerce opportunities. They imagine the government or private companies might use the space hotel for training crews heading to the moon, Mars and beyond.
The eventual goal, as the team put it in 2019, is "to create a starship culture where people are going to space, and living in space, and working in space. And we believe that there's a demand for that."
1. What can we learn about the space hotel from the text?| A．Its construction has already begun. | B．It has been delayed due to Covid-19. |

6 . Caroline Woodward wakes each morning to the sound of waves crashing onto the rocks that surround her home, Lennard Island, British Columbia, Canada.
This rocky island is home to a bright white lighthouse with a fire engine red top. Lennard Island's lighthouse has been a fixture of the Western Canadian coast since 1904, when the first wooden lighthouse was built to guide sailors navigating the surrounding waters.
There's been a lighthouse keeper on Lennard Island ever since, and today, that job falls to Woodward, who also writes poetry and children's stories, and her husband Jeff George.
"I think many people have romantic, 19th century ideas of lighthouses," says Woodward. Not many of them are correct, she says.
No, she doesn't live in the tower itself — and no, she doesn't have much time to kill. What Woodward does have is a busy, fun, and rewarding role, one she wouldn't trade for the world.
Woodward and George take turns to send a 3:15 a.m. weather report to the local Coast Guard radio. It's the first of seven they deliver each day. They survey the sea and sky from the lookout points. Their routine work also involves maintaining the twelve buildings that make up Lennard Island Lightstation.
The couple work seven days a week — vacations come only when the Coast Guard organizes relief keepers. In between, there's time for tending to the garden, hiking, and keeping watch on the wildlife that populates Lennard Island and its spectacular surrounds.
"We have resident bald eagles, lots of gulls, crows, and water and shorebirds all the year round. We also host Pacific tree frogs and wonderful insects."
There are, fortunately, no bears or wolves, says Woodward.
The wildlife and landscapes provide plenty of inspiration for her writing, too. Woodward has recently finished a novel, which she says was inspired by the stunning surrounds of the North Pacific Ocean.
1. Which of the following is a duty of the lighthouse keepers?| A．Living in the tower of the lighthouse. | B．Sending seven weather reports daily. |
| C．Taking care of the garden. | D．Observing the wildlife on the island. |
| A．She values her job greatly. | B．She finds her job boring. |
| C．Reality disappoints her. | D．She wants to change her job. |
| A．She lives a romantic life there. | B．She secures long vacations. |
| C．Her creativity in writing is inspired. | D．Her physical health is improved. |
| A．Why Woodward becomes a lighthouse keeper. |
| B．What it is like to be a lighthouse keeper. |
| C．How the lighthouse keepers kill the time. |
| D．Where Woodward continues writing. |
