1 . Both of my parents worked fulltime when I was a little girl，so my grandmother would stay at our house during the day. We would watch game shows in the living room. Our favorite was The Price Is Right. We would call out our answers along with the contestants.
When I got older and started going to school，we couldn’t watch our game shows regularly. That was okay with me，though，because the one thing I liked better than watching game shows with my grandmother was helping her bake cakes. Watching her in the kitchen was amazing：she never seemed to need the recipes（食谱）but everything she made tasted delicious.
At first I would just sit in the kitchen and watch，even though I didn’t understand what she was doing. As I got older，she let me help with the easy parts，such as measuring the sugar. The day she let me separate the eggs，I felt like I had found complete pleasure.
At last，my parents decided that I could take care of myself，and my grandmother stopped coming over every day. The love of baking，however，stayed with me. I started baking by myself，and even if the cookies ended up burnt sometimes，more often they turned out pretty well. I tried out new recipes，and whenever I got to a thorny part，I would call my grandmother for advice. Sometimes I would call her just to talk too. I felt like I could talk to her about anything.
My grandmother passed away ten years ago，but I still think of her every day. Last week，I found a recipe book she made for me. It included her recipes for brownies，cookies，and my favorite，lemon pie. As I looked through the pages，I thought I could hear her voice. She was the one who taught me not just about baking，but about life.

2 . What is a hero? We may think of the fictional characters with supernatural powers or great people who can influence world events. Now, as the nation continues its all-out efforts to fight against the novel coronavirus pneumonia(COVID-19), medical staff have become heroes in the eyes of the public.
As of Feb 19, a total of 32,000 medical staff outside Hubei province have been working to treat patients around the center of the outbreak.
Zhang Dingyu, the president of Wuhan Jinyintan Hospital, is one of these heroes. Since the hospital received the first seven patients in December, Zhang has been so busy that he barely gets any sleep. Even suffering from amyotrophic lateral sclerosis (肌萎缩侧索硬化), the 56-year-old doctor is doing his best to quicken his pace to save precious time for infected patients. “I have to run, racing against time to save more patients from the deadly disease, because I don’t have much time left in my life,” Zhang told Xinhua News Agency.
With the duty of saving lives, many medical professionals like Zhang have been working long hours for days, despite their fear and worries.
Lu Jingjing from Wuhan Children’s Hospital also works at a temporary mobile hospital. She does not let her parents know that she is now working with novel coronavirus-infected patients.
When her parents ask for a video chat, Lu says she is working and lets her husband and children chat with them instead.
“It’s dangerous but we should win the battle with the virus as soon as possible, so that medical staff and patients can go back home,” she told China Daily.
US writer Khalil Gibran (1883-1931) once wrote, “Tenderness and kindness are not signs of weakness and despair, but the manifestations of strength and resolution.” It’s true for the medical workers.
Everyone has fear, especially when it comes to deadly diseases. But for medical staff, saving lives comes first and is enough for them to be brave and stay on the front. They may look like ordinary people in daily life, but in these extraordinary times, they are heroes.

3 . History tells us that footwear was one of the first things ancient people learned to make. Footwear helped them across rocky paths or hot sands without injuring themselves. The earliest footwear we know of was simply a piece of plaited (编织的) grass or leather tied to the feet.
The ancient Egyptians seem to have invented the first footwear with a firm sole (鞋底) — sandals. Egyptian royalty usually wore sandals that had a different style from those with lower status (身份), while slaves were not allowed to wear anything on their feet. The sandal is still the basic form of footwear in many countries, particularly those with a hot climate, whereas in cold climates, an entirely different type of shoe appeared — the moccasin — a slipper-shaped shoe made of soft but strong leather.
The Greeks were the first to develop shoes with heels (鞋跟). Then, in the Middle Ages, shoes with long points at the toe became very chic for the nobility. These shoes were often very difficult to wear. Other trends followed, with square-toed shoes, wide shoes, and even shoes that could make a woman stand two feet taller. Not surprisingly, these sometimes led to accidents. Even today, fashion rather than comfort often leads to the kind of shoes women wear.
Mechanical shoemaking appeared in the 1800s in North America. Until then, shoes had been made with the same kinds of hand tools used by the ancient Egyptians. And in 1858, a machine was invented that could stitch (缝合) the sole of a shoe to the upper part. Now it was possible to make shoes that were shaped to fit either the left or right foot. Toward the end of the 1800s came a new type of shoe that was specifically designed for sports — the sneaker — and it soon become an all-time favorite.

4 . A study of 27,000 men showed those skipping (不吃) breakfast were at a greater risk of heart problems. The British Heart Foundation said breakfast helped people resist (抵制) sugary snacks before lunch.
The men, aged 45-82, were studied for 16 years. During that time there were more than 1,500 heart attacks or cases of deadly heart failure. However, people who skipped breakfast were 27% more likely to have heart problems than those who started the day with a meal. The researchers took into consideration other lifestyle risk factors (因素) such as smoking and exercise.
Researcher Dr Leah Cahill told the BBC: “The take-home message is to eat in the morning when you wake up, preferably within an hour. The results show that something is better than nothing, but it’s always better to have something healthy and balanced.”
She said the timing of the meal seemed to be key and waiting until lunch rather than “having breakfast” may be straining (损伤) the body over time. This could be increasing the risk of high blood pressure and fatness which could in turn damage the heart. “Don’t skip breakfast,” Dr Cahill suggested.
Victoria Taylor, an expert with the British Heart Foundation, said: “These researchers only looked at men aged over 45, so we would need to see further research to prove that breakfast has the same effect on the heart health of other groups of people. What we do know is that a healthy breakfast can make that mid-morning biscuit less tempting, as well as giving you another opportunity to widen the variety of foods in your diet. Cereals (谷类食品) with low fat milk are a good way to start the day. Try a banana or dried fruit on top and you’ll be on your way to a fine day before you’ve even left the house.”

5 . Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates（灵长类）to be cloned. Another one named Tetra was produced in the late 1990s by embryo（胚胎）splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus（原子核）with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer（SCNT）, can create more clones and allows researchers greater control over the edits they make to the DNA.
Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn’t been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers’ pouring water on the idea that the team’s results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.
But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

6 . Macdonald paused a moment in front of the burning car. Flames six feet tall poured from the engine, the smell of melting rubber heavy in the air. For a few seconds, Macdonald thought about whether the car would explode, killing them both. He thought about how lucky he was to have already just survived a head-on collision between his truck and the red Chevy Cobalt now in flames. Was he ready to risk his life to save the man that he believed could have ended his?
The two-vehicle collision happened at 3:44 p.m. on Monday south of New market. Macdonald was heading to work when he says another car swerved into his lane, hitting him head-on. Soon after the collision, the other driver’s car burst into flames with him trapped inside. Macdonald, 25, came to a decision. He would try to save the man’s life. He ran to the car. The driver’s side door was blocked but the passenger’s door was pushed open by the driver, a 64-year-old man now barely conscious. Hardly noticing the heat, Macdonald opened the door and grabbed the shoulder of the driver’s jacket. He dragged the man about 15 feet before two bystanders came to help him pull the man to a safe distance. Moments later the entire car was on fire.
The police confirmed the other driver was charged with careless driving. Macdonald escaped the crash with whiplash, sore muscles and wrists from the airbag release, and a headache. The other driver received serious but non-life threatening injuries, said the police.
Macdonald is just grateful that both of them came out alive. “I’m just glad I stood up when I was needed,” said Macdonald. “You only get a couple of chances in your life to prove what you are made of.”

7 . Nothing could stop Dad. After he was put on disability for a bad back, he bought a small farm in the country, just enough to grow food for the family. He planted vegetables, fruit trees and even kept bees for honey.
And every week he cleaned Old Man McColgin's chicken house in exchange for manure(肥料). The smell really burned the inside of your nose. When we complained about the terrible smell, Dad said the stronger the manure, the healthier the crops, and he was right. For example, just one of his cantaloupes filled the entire house with its sweet smell, and the taste was even sweeter.
As the vegetables started coming in, Dad threw himself into cooking. One day, armed with a basket of vegetables, he announced he was going to make stew(炖菜).Dad pulled out a pressure cooker and filled it up with cabbages, eggplants, potatoes, corns, onions and carrots. For about half an hour, the pressure built and the vegetables cooked. Finally, Dad turned off the stove, the pot began to cool and the pressure relief valve sprayed out a cloud of steam. If we thought Dad's pile of chicken manure was bad, this was 10 times worse. When Dad took off the lid, the smell nearly knocked us out.
Dad carried the pot out and we opened doors and windows to air out the house. Just how bad was it? The neighbors came out of their houses to see if we had a gas leak!
Determined, Dad filled our plates with steaming stew and passed them around. It didn’t look that bad, and after the first wave had shut down my ability to smell, it didn’t offend the nose so much, either. I took a taste. It would never win a prize in a cooking competition, but it was surprisingly edible, and we drank up every last drop of soup!

According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the effect is greater, the younger people learn a second language.
A team led by Dr Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of "early bilinguals" who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.
"Our findings suggest that the structure of the brain is changed by the experience of learning a second language," said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. "Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),"he said. "You are actually going beyond language and have a better understanding of different ideas."
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and 34. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. "Studying a language means you get an entrance to another world," explained the scientists.
