1 . Although vaccines are required for entry into school in most places in the United States, the government does allow for exceptions, like religious reasons.
In the last few years, the rates of vaccine-preventable illness have been on the rise. In most cases, these outbreaks began with children who were unvaccinated. To deal with this threat, some schools in New York have been refusing to allow unvaccinated children to attend school. Several parents thought this was unfair and filed lawsuits. Just recently, though, a court ruled in favor of the city schools.
The court made the right decision. Vaccine policy depends not only on the added protection that vaccines provide for those who get shots, but also on the decreased likelihood that anyone will come into contact with the disease. This is known as community immunity. It refers to the fact that when enough people are immunized, then there really can’t be an outbreak. And if there can’t be an outbreak, then everyone is protected.
This is important, because there are people who cannot be given immunizations for various reasons. For example, small babies can’t be given all vaccines.
In 1995, the chicken pox vaccine was introduced in the United States. Over time, more and more children received it. In 2011, a study looked at how the program affected the number of children who died from the disease.
The first thing noted in the paper was that death from chicken pox went down considerably after the vaccine was introduced. From 2001 through 2007, the rates of death remained much lower, with just a few children dying from chicken pox nationally each year.
What’s more from 2004 through 2007, not one child less than 1 year of age died in the United States from chicken pox. This is important, because we cannot give the chicken pox vaccine to babies. In other words, all those babies were saved not because we vaccinated them against this illness, but because older children were.
Therefore, people who refuse to vaccinate their children aren’t just putting themselves at risk — they’re putting everyone else in danger, too.

2 . Having worked for more than a decade in finance in the oil industry in Canada, Tori Fahey found herself wanting more from life. But it wasn't through desperation that her circumstances changed: “I didn't get fed up and storm off, nothing like that; it was curiosity about other interests and wanting to experience something new.”
Fahey left her job and completed an MBA before setting up a move to New York to begin a degree. However, the opportunity of an open year between the MBA and the degree came up, and as a keen touring cyclist, Fahey realised that a much dreamed-about adventure was now becoming a possibility: "The ride in Africa had been on my fantasy list. It was a moment when I realised that I could do anything, so I should."
Fahey rode across Africa, a 7,500-mile trip that took four months. The whole experience had a life-changing impact. Fahey said: “Bicycles provide a literal freedom. You don't allow yourself to feel like that in everyday life because there are so many distractions. But when you' re out on the bike and there's nothing else, you' re really free to experience what life is.”
Post-degree, Fahey worked on projects with the UNDP(United Nations Development Project) in Montenegro with the aim of bringing investment to rural communities.
It was while working on these projects that the seeds were sown for the next new investment. “It was through my trip across Africa that I discovered pannier and rack systems inconvenient and I was never going to use them again.” Little did she know this would lead her to start up her own company.
In 2013, Apidura was born, producing storage solutions for people looking to travel the world by bike, race across continents and carry all they need to do so. It's now a successful global brand, but Fahey remains reflective about what else the company can do for people.

3 . For many years doctors have warned us about the dangers of stress (压力) and have given us advice about how to cut down our stress levels. Everyone agrees that long-term stress, for example having to look after someone who has a chronic (慢性的) illness, or stressful situations where there is nothing we can do, for example being stuck in a traffic jam, should be avoided whenever possible. However, some medical experts now believe that certain kinds of stress may actually be good for us.
Dr Marios Kyriazis, an anti-ageing expert, points out that what he calls "good stress” is beneficial to our health and may, in fact, help us stay young and attractive and even live longer. Dr Kyriazis says that “good stress” can strengthen our natural defences which protect us from illnesses common among older people, such as Alzheimer's and heart problems.
According to Dr Kyriazis, running for a bus or having to work to meet a deadline are examples of “good stress”, that is situations with short-term or low stress. The stress usually makes us react quickly, and gives us a sense of achievement — we did it! However, in both situations, the stress damages the cells(细胞) in our body or brain and they start to break down. But then the cells own repair mechanism “switches on”and it produces proteins which repair the damaged cells and remove harmful chemicals that can gradually cause disease. In fact, the body's response is greater than is needed to repair the damage, so it actually makes the cells stronger than they were before.
“As the body gets older, this self-repair mechanism of the cells starts to slow down,” says Dr Kyriazis.“The best way to keep the process working efficiently is to ‘exercise’ it, in the same way you would exercise your muscles to keep them strong. This means having a certain amount of stress in our lives.”Other stressful activities that Kyriazis suggests as being good stress include redecorating a room in your house over the weekend, packing your suitcase in a hurry to reach the airport on time, or shopping for a dinner party during your lunch break.
So next time your boss tells you that she wants to see the report finished and on her desk in 45 minutes, don't worry; just think of it as “good stress” which will benefit your long-term health!

4 . NOT that long ago, the world wondered whether clean energy could survive without government support. Now the question is how far it can spread. The number of electric vehicles, which was about 1 million in 2015, last year reached 2 million. In electricity generation, too, trend is with the greens. In the first half of this year wind, solar and hydro generated a record 35% of Germany's power.
Greater success is breeding greater ambition. California is proposing to reach 60% renewable energy by 2030. 176 countries have clean-energy goals. Hawaii, America's most oil-dependent state, has promised to be 100% renewable by the middle of the century and so have 48 poor countries vulnerable to climate change. This week the number of multinationals making a commitment to running their operations on 100% renewable energy rose to 100.
But not every target is helpful. To see why, consider that goal of 100% renewable energy. It makes solving climate change seem easy. In fact, though wind and solar can generate the whole country's electricity some day, renewables still account for less than 8% of the world's total power output. Moreover, cleaning up electricity is only part of the battle. Even though gas-fired heating and cooking can be at least as big a source of greenhouse-gas emissions, renewable heating gets little attention. Transport policy is unpredictable, too. Carmakers may hit their goal of annual sales of 10 million electric vehicles in a decade, but battery-powered road transport, shipping and aviation are dreams. A much-quoted claim that America could rely on wind, solar and hydro alone for its electricity has recently been bitterly criticized by a group of respected academics.
Most importantly, a 100% renewables target confuses means with ends. The priority for the planet is to stop net emissions（净排放量）of greenhouse gases, especially carbon dioxide. Putting too much emphasis on wind, solar and other renewables may block off better carbon-reduction paths. New technologies, such as "direct air capture" systems designed to separate carbon dioxide from the air, may in time prove vital. Likewise, greater energy efficiency could reduce emissions by even more than using renewables would.

| D．The target of 100 renewables is too high to reach. |
5 . It is not easy to excite New Yorkers. This is one reason why actors and other famous people move to the city. They can live quieter lives and escape the paparazzi(狗仔队)photographers who would follow then in Hollywood.
But New York has a new media star. And this star is not living so quietly.
The star is a colorful Mandarin duck. The bird first appeared this month in a small body of water in Manhattan's Central Park.
Large crowds have gathered to see the duck. Reporters have been following its every move. The media attention on the duck has earned the name "quackarazzi"-a word combination of paparazzi and the sound a duck makes!
The duck has chosen to live in a costly pan of New York-just off Fifth Avenue, near the historic Plaza Hotel. There, hundreds of people turn up every day, hoping to see the bird show off its extremely colorful feathers.
Many people like the duck because its colors are like "sunsets," says New Yorker Joe Amato. He comes to the park nearly every day with his camera equipment.
Bird expert Paul Sweet heads a large collection of bird species at the New York-based American Museum of Natural History. He says there is nothing special about a Mandarin duck in Central Park. Central Park Zoo has its own Mandarin duck, he says. These ducks are often imported to the United States from Asia for use on private property.
Sometimes they escape, he said. Sweet said he believes this duck is an escapee. If it were wild, he added, traditional bird watchers-often called birders-would be "very excited." And they are not. "A lot of non-birders tend to see colorful birds as more beautiful," Sweet said. "But to me, it's no more beautiful than, say, a sparrow."
In this case, though, common New Yorkers get to decide what is beautiful. And they have clearly chosen this Mandarin duck.

6 . Johnny Cash was born in 1932 in the southern state of Arkansas. His parents were poor cotton farmers. As a school boy, he began writing songs and he performed on radio programs. After high school, he joined the United States Air Force and served as a radio operator in Germany.
He returned to the United States in 1954 and formed a band with two friends and performed at local events. They began recording for Sun Records in Memphis. One of the songs Cash wrote became the first country music hit record for the company. It was “Cry, Cry, Cry.”
Johnny Cash performed all across the United States and Canada. By 1958, Johnny Cash was a successful recording artist, songwriter and singer. He was invited to perform at the Grand Ole Opry in Nashville, Tennessee.
Johnny Cash won many awards, including eleven Grammy Awards and the Kennedy Center Honors. He was elected to both the Country Music Hall of Fame and the Rock and Roll Hall of Fame. He also received a Grammy Lifetime Achievement Award.
He died on September 12, 2003, in Nashville at the age of seventy-one.
Fans say that Johnny Cash's music was important because it told simple stories about life and death. They say he cared about social issues and continued to express support for those who are poor and without political power. One of the last songs he recorded was one made popular by the rock and roll group Nine Inch Nails. It is called “Hurt.”

7 . Many people have their breakfast with a glass of milk. Right now, cows, buffalos, goats and sheep provide most of the world’s milk. But soon, people could get milk from roaches (蟑螂).
That isn’t as crazy as it might sound. New research shows this “milk” is super-nutritious. What’s more, some scientists have already found milk from a lot of insects.
In 2004, Subra Rama started studying milk crystals found inside the roach. At the time, he was teaching biochemistry at the University of Iowa City.
To learn more about the milk crystal from roaches, the scientists used X-rays to look at the atoms in it. The data revealed the chemical secret of the roach crystal. They showed that roach milk is a “complete food”. It contains sugar with a fatty acid stuck to it. Fatty acids are the building blocks of fats. The protein in the milk is also full of essential amino (氨基的) acids, which are the building blocks of proteins. Since our bodies can’t produce the “essential” ones, we need to get them from our food. And so do baby roaches.
Barbara Stay, a biologist at Iowa University, also worked on the new study. She says the new data show that the roach milk is “three times more nutritious than cow’s milk and four times more nutritious than buffalo’s milk”.
Rama would like to see roach milk turned into a protein supplement to feed hungry people. But not everyone is confident that it can be done.
Marcel Dicke studies insects as a potential source of human food at Wageningen University in the Netherlands. Dicke says this is a “sound study”. However, in his opinion, “Extracting (提取) milk from roaches can only likely be done in a destructive way with only small quantities”. That means you’d have to raise and kill many bugs to get very little milk.

8 . Light and bright, cheap and cheerful: IKEA's 400-plus outlets （专营店）in 49 countries all run on the same central principle. Customers do as much of the work as possible, in the belief they are having fun and saving money. You drive to a distant warehouse built on cheap out-of-town land. Inside, you enter a maze （迷宫）---no shortcuts allowed—where every twist reveals new furniture.
Compared with the prices of other outlets, IKEA's are much lower. You load up your trolley （手 推车）with impulse buys—a clock, storage boxes, tools and more chairs than you will ever use. You drag cardboard boxes, cupboards and tables into your car and reward yourself for your economy and good taste. Then you drive home and put your prizes together. You are satisfied with the bargains. IKEA is satisfied with your money.
The company's name was a do-it-yourself job, too. IKEA stands for Ingvar Kamprad, from Elmtaryd―his family's farm—in Agunnaryd. That village is in the Smaland region of southern Sweden. Mr Kamprad founded IKEA aged 17. Well before that, he spotted a principle which would make him one of the richest men in the world that customers like buying goods at wholesale prices （批发价）.First he bought matches in large quantities and sold them by the box. Aged ten, he sold pens in the similar way.
Setbacks inspired him. Facing a price war against his low-cost mail-order furniture business, he defeated competitors by opening a showroom. Dealers tried to crush Mr Kamprad and banned him from their trade fairs. He slipped in, hiding in a friend's car. When they tried to threaten his suppliers, he relied on his own workers, and secretly sold his production to communist Poland. Decades later, east Europeans freed from the planned economy drove hundreds of miles to newly opened outlets in Moscow and Warsaw.
His self-discipline was world-famous. As a child, he removed the "off' button from his alarm clock to stop himself oversleeping. He rarely took a first-class seat. The wine didn't get you there any earlier, he sniffed; having lots of money was no reason to waste it. He bought his clothes in second-hand markets, and for years drove an elderly Volvo until he had to sell it on safety grounds. He had his hair cut in poor countries to save money. Visitors admired the views, but were surprised that his house was so shabby. He worked well into his eighties.
His diligence and simple way of life set a good example to his 194,000 "co-workers". But he was not mean. The point of cutting costs was to make goods affordable, not to compromise quality. He urged his staff to reflect constantly on ways of saving money, time and space. An improved design that allows easier piling means shipping less air—and more profit.
Culture was more important than strategy. He disliked ''exaggerated （夸张的）planning", along with financial markets and banks. Better to make mistakes and learn from them. And use time wisely: "You can do so much in ten minutes. But ten minutes once gone are gone for good." This did not apply to customers. The longer they stayed, the better.
Mr Kamprad's impact on modern life can be compared with that of Henry Ford and the mass-produced motor car. Furniture used to be expensive, dark and heavy. For many people, decorating a home could cost many months' salary. IKEA made furniture not just affordable and functional, but fun. The mission was civilizational, he felt, changing how people lived and thought.
His approach drew some fire. The company values struck some as unpleasant. At IKEA's Corporate Culture Centre, lots of pictures of Mr Kamprad with his mottos can be seen everywhere. What's worse, some parts of the supply chain seemed to have serious problems to overcome.

9 . During the outbreak of novel coronavirus, cities are locked down and borders are closed. Science, on the contrary, is becoming more open. And this "open science" is already making a difference.
Soon after the epidemic started in China, a research team from Fudan University in Shanghai successfully sequenced （测定序列）the DNA of the virus. But they didn't keep the information to themselves. Instead, they placed the sequences on GenBank, an open-access data platform, so researchers around the world could download them for free and start studying the virus.
Due to this openness, pharmaceutical （制药的）companies across the globe are now able to work simultaneously （同时地）to develop a vaccine. “There may be room for multiple different vaccines for different purposes and different age groups,”, Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security in the US, told Al Jazeera. "The bigger menu we have of vaccines, the more resilient （有适应力的）we'll be against coronavirus outbreaks in the future.”
Major drug companies around the world are also sharing their study results. Remdesivir, a drug originally developed by US company Gilead Sciences to treat Ebola, is found to be promising in fighting against the novel coronavirus. Currently, two trials of the drug are already underway in China, and the results might be available as soon as April, according to The Verge.
This openness in science is going to be even more critical in the future. “With climate change, increasing globalization, and population shifts, epidemics will not go away, and might even become more frequent," Dan Barouch, a Harvard Medical School professor, told Harvard Magazine.
He said, "No one group can do everything. It has to be a coordinated （合作的）approach. But I do think that the world has a greater sense of readiness this time to develop knowledge, drugs, and therapeutics （疗法）very rapidly.”
Every epidemic is indeed a crisis, but it can also be a learning opportunity. One redeeming （补偿的）factor of the COVID-19 outbreak is that it is helping science adapt for the better.

10 . A short while ago, I lost access to my WeChat account. I am not sure why it wouldn’t let me log in; perhaps it was my ancient, out-of-date phone. But I wasn’t too upset because it offered me an opportunity to take a break from social media — something more and more people are doing.
In the United States, Twitter is losing millions of users each month and Facebook has seen a 44 percent decline among its younger users. Some of these users may have deserted Twitter and Facebook for other social media platforms, while many others have quit because they felt that social media was having a negative effect on their happiness and overall quality of life.
Stars such as Taylor Swift and Ed Sheeren have taken a break from social media because they were tired of many Internet trolls (网络喷子) leaving negative comments. Ordinary people (like me) are turning away from it because of the feeling that they were spending more time online and enjoying it less.
It is not unusual for people to spend two or three hours a day posing or reading posts, to the point where it becomes an addiction. And it is an addiction. There is a chemical in your brain known as dopamine (多巴胺) which is sometimes called the “reward molecule” and its release gives you a feeling of pleasure. For instance, when you post a photo on WeChat and get a hundred likes, you feel happy. That’s dopamine at work.
In my case, being off WeChat left me with a feeling of anxiety for a few days. No doubt I missed my dopamine. And I got e-mails from friends wondering if I was fine or if I was just being anti-social. But I soon began to feel quite peaceful and started to worry less about what other people were doing and concentrate more on my personal life. And it is an added bonus that I’m getting better sleep at night.
I’m not advocating that all of you quit social media, but spending less time on these platforms does bring you advantages. You could start by leaving your phone at home when you go to school (For some, that’s already a school rule). And it is also a good idea to charge your phone outside of your bedroom at night, as you are unlikely to get a good night’s sleep when the notification (通知) bell keeps ringing.
Someday I may reconnect with my WeChat account, but I’m not in a hurry. Life can be more relaxing and just as interesting without it.
