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 . 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.
1. Which sentence can be used to describe Tabby?| A．She was so lovely that she could be easily adopted. |
| B．She suffered a lot from the disease-epilepsy. |
| C．She was so strong that she could run very fast. |

| 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. |

| C．Love is Everywhere: a Poor Dog | D．Take Me Home: My Dear Boy |
3 . When you think of the Himalayas, you may picture tall, rocky, snow-covered peaks. But that’s not true.
The subnival (亚冰雪的) region is the zone between the treeline and the snowline. It is 5 to 5 times as large as the areas of glaciers and permanent snow, which means studying it is vital to understanding the Himalayas as a whole.
The treeline is the edge of an ecosystem where trees are able to grow, and beyond the treeline environmental conditions become too tough to allow tree growth. Meanwhile, snowlines are the boundaries on mountains that separate areas with permanent snow (where snow is present for the majority of the year) from areas with seasonal or no snow.
Researchers used satellite data from 1993 to 2018 to measure plant cover between 4,150 meters and 6,000 meters above sea level. The scientists discovered that the greatest increase in plant cover was between an altitude of 5,000 meters and 5,500 meters. Subnival plants mostly include small shrubs and grasses.
Even areas once completely occupied by glaciers now hold rocks covered with mosses, lichen, and sometimes even flowers. In addition, the snowline seems to be retreating, while the treeline is expanding. This shows that the region is becoming warmer, causing more melting of snow and allowing vegetation to move up in height.
In the past 40 years, 25% of all Himalayan ice has been lost due to global warming. Himalayan glaciers are reducing by about 0.5 meters each year. The rate of glacier melting has doubled in this decade. The melting of glaciers increases water in the region, making it wetter. Receding snow also forces the snowline to move up, providing a greater amount of area for the warm and moist conditions, which are perfect for vegetation growth.
As of now, we do not know whether vegetation will accelerate or slow down the rate of glacier melting.

4 . I first began to wonder what was doing on a college campus when my parents drove off, leaving me alone in a parking lot, wanting nothing more than to find my way safely to my dorm room. The fact was that no matter how mature I liked to consider myself, I was feeling just a bit first-gradish. Adding to my distress was the impression that everyone on campus was watching me. My plan was to keep my ears open and my mouth shut and hope no one would notice I was a freshman.
With that thought in mind, I raised my head, squared my shoulders, and set out in the direction of my dorm, glancing at the campus map in my hand. And then I spent the afternoon seeking out each of my classrooms so that I could make perfectly timed entrance before each lecture without having to ask silly questions about its whereabouts.
The next morning, I found my first class and marched in. I chose a seat in the first row and to the side. I was in the front, but out of the professor's direct line of vision. Then I opened my anthology（选集）of American literature and looked at the date at the top of a page. "Welcome to Biology 101," the professor began. Cold sweat broke out on the back of my neck. I got out my schedule and checked the room number. I was in the right room. Just the wrong building!
So now what? Get up and leave in the middle of the lecture? Wouldn't the professor be angry? Wouldn't they all stare at me? Forget it, I settled into my chair.

6 . Short and shy, Ben Saunders was the last kid in his class picked for any sports team. “Football, tennis cricket-anything with a round ball, I was useless”, he says now with a laugh. But back then, he was the object of jokes in school gym classes in England’s rural Devonshire.
It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Saunders set his mind building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon.
The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway’s school of Adventure in Scotland, where he learned about the older man’s cold-water exploits (英勇行为). Intrigued, Saunders read all he could about Arctic explorers and North Pole expeditions, then decided that this would be his future.
Journeys to the Pole aren’t the usual holidays for British country boys, and many people dismissed (不予考虑) his dream as fantasy. “John Ridgway was one of the few who didn’t say, ‘You are completely crazy’,” Saunders says.
In 2001, after becoming a skilled skier, Saunders started his first long-distance expedition toward the North Pole. He suffered frostbite, had a closer encounter with a polar bear and pushed his body to the limit.
Saunders has since become the youngest person to ski alone to the North Pole, and he’s skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.
This October, Saunders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, an 1800-mile journey that has never been completed on skis (滑雪板).

7 . The weather is getting hotter and you’ll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you pour down your throat. Something that looks cool may not be good for your health.
There are plenty of so-called energy drinks on the market. Most of them have an attractive color and cool name. Their nutrition lists also contains various things from vitamins to ginseng. Sounds great!
But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.
Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.
There are potential health dangers linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.
Teenagers should be discouraged from taking drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.

8 . Very often, when we see young people sitting there, looking at the screen of a mobile phone and smiling, we may think nothing is wrong. But when we come to the question “how much time do they actually spend on media（传播媒介）daily?”, the answer is surprising: young people spend about nine hours every day using media, and this only includes media used for enjoyment.
Today's young people seem to have become crazy multitaskers. They often use media when doing other activities. Some watch TV when doing homework, some text（发短信）, and some others listen to music. But what do young people think of this? A research showed that two thirds of them believed watching TV or texting had no influence on their schoolwork. Half of them thought using social media made no difference. However, researches have given a different answer: “media multitaskers” did worse in tests.
Scientists did a research among more than 400 students. It shows that those who text a lot have more trouble sleeping and do worse in their study. In another research, students who didn't text during a lesson took down a lot more notes than those who were texting. A similar research also found that students who texted when doing schoolwork had lower overall（总体的）grades.
According to a research, if a kid uses social media a lot, especially at night, he or she will sleep worse and feel more nervous and depressed（消沉的）. On the one hand, young people stay up late to check messages and information. They may also be woken up by messages they receive. On the other hand, even the light from a screen could influence their sleep. Some other researches also show that children who use media at night go to bed later, get fewer hours of sleep each week, and become sleepy more easily during the daytime.

| C．The use of social media has both advantages and disadvantages. |
| D．Mobile phones are the main tools students use for school learning. |
9 . The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.
Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.
Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.
The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business.
To raise money for the idea, he toured the city's private companies which fund new business and found a supporter in the finance group Mint. He introduced his idea to four of Mint's directors and won their support. Mint has committed around £ 500,000 to Myhabs and taken a share of 30 percent in Mr. Dunlop's business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.
Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.
For music events, the cardboard houses will be ordered online and put up at the sites by the Myhabs team before the festivalgoers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior advertising space.
The biggest festivals attract tens of thousands of participants, with Glastonbury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.
1. “Ecofriendly tents” in Paragraph 1 refer to tents ________.| A．economically desirable | B．favorable to the environment |
| C．for holding music performances | D．designed for disaster relief |
| A．independently with an interest free loan from Mint | B．with the approval of the City's administration |
| C．in partnership with a finance group | D．with the help of a Japanese architect |
| A．the weather in the UK is changeable in summer |
| B．most performances at British festivals are given in the open air |
| C．the cardboard tents produced by Mr. Dunlop can be user-tailored |
| D．cardboard tents can be easily put up and removed by users |
10 . Great Barrier Reef Choking on Pollutants
Attempts to protect the Great Barrier Reef are failing. A report released Monday by the government in Australia says water quality in the Great Barrier Reef is far below what it should be. It showed that pollution have decreased, but not enough to reach environmental targets.
Sediment (沉淀物) and chemicals can weaken coral, hurting its ability to feed and grow. Coral are live animals that take root in the ocean floor, but they are not plants. Reefs are the hard skeletons (骨架) left at the bottom of the sea by small marine creatures called polyps (珊瑚虫). The polyps then form the larger structure of a reef. Corals also are some of the most diverse ecosystems on the entire planet. They can make a home for invertebrates, crustaceans, fish, and sea snakes.
Steve Miles is Queensland’s environment minister. He says the research shows the Reef needs more protection. “Over that five-year period, we did see some progress towards our targets. Sediment is down 12 percent and pesticides (杀虫剂) loads are down 30 percent. But what is most disturbing is that these results are far from our targets. Progress towards these targets flat-lined in the period 2013-2014. If one of my kids came home with a report card like this, I would be a bit disappointed. There is more bad news here than good news. ” said Steve Miles.
The report also found that fewer than one-third of Queensland’s sugar plantations used techniques to reduce the use of pesticides. Only 28 percent of land managers managed their land properly. They had reduced harmful water run off to protect the health of the Reef. The official target is a 90 percent reduction in pesticide use within three years.
Scientists at the University of Queensland and the Australian Institute of Marine Sciences published their findings Wednesday, July 18 in the journal Science Advances. It found between 1992 and 2010, the recovery rate dropped by an average of 84 percent. But there is hope. The study also found some corals can recover quickly if “acute and chronic stressors” are lessened.
Meanwhile, the Australian government released its updated reef protection plan Friday. It clearly states global temperatures must be stopped from rising in order to save the world’s largest living structure.
