People from all over the world visit Disneyland to have fun, not to get sick. But last week， an outbreak of measles（麻疹）spread from the Southern California theme park. As of Monday, January 19, at least 52 people have got the easily spread illness.

    The majority of the reported cases of measles are from people who visited the park before. According to the California Department of Public Health, these people were exposed to the illness at Disneyland from December 17-20.

    Officials believe the cause is likely someone who caught measles abroad and visited Disneyland, but this has yet to be proved. However, in 2014, California had its highest measles infection rate in nearly twenty years. There were 66 cases of measles reported in the state―23 of them in Orange County, where Disneyland is located.

    Measles spreads very easily. It can be caught from coughing and sneezing. Crowded areas like theme parks are especially suitable for its spread.

    The illness starts with a fever and develops into symptoms including a cough， runny nose, red eyes and so on. About three out of ten people infected with measles will develop another health problem, including an ear infection or pneumonia(肺炎).

    The best way to guard against measles is to get vaccinated(打疫苗). An unvaccinated person is 35 times more likely to catch measles than someone who received a vaccination.

    If you could be anybody in the world, who would it be? Your neighbour or a super star? A few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality（虚拟现实）device. Rikke Wahl, an actress, model and artist, was one of the participants in a body swapping experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She swapped with her partner, an actor, using a machine called The Machine to Be Another and temporarily became a man. "As I looked down, I saw my whole body as a man, dressed in my partner's pants," she said. "That's the picture I remember best."

    The set-up is relatively simple. Both users wear a virtual reality headset with a camera on the top. The video from each camera is sent to the other person, so what you see is the exact view of your partner. If she moves her arm, you see it. If you move your arm, she sees it.

    To get used to seeing another person's body without actually having control of it, participants start by raising their arms and legs very slowly, so that the other can follow along. Eventually, this kind of slow synchronised（同步的）movement becomes comfortable, and participants really start to feel as though they are living in another person's body.

    Using such technology promises to alter people's behaviour afterwards-potentially for the better. Studies have shown that virtual reality can be effective in fighting racism-the bias（偏见）that humans have against those who don't look or sound like them. Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people's associations between, for instance, black people and adjectives such as good, bad, athletic or awkward. Then they asked them to control the body of a dark skinned digital character using virtual reality glasses, before taking the test again. This time, the participants' bias scores were lower. The idea is that once you've "put yourself in another's shoes" you're less likely to think ill of them, because your brain has internalised the feeling of being that person.

    The creators of The Machine to Be Another hope to achieve a similar result. "At the end of body swapping, people feel like holding each other in their arms," says Arthur Pointeau, a programmer with the project. "It's a really nice way to have this kind of experience. I would really, really recommend it to everyone."

    Saving money is a golden rule in everyday life. And in the western countries it is especially obvious. As prices and building costs keep rising, the "do-it-yourself" (DIY) trend in the US continues to grow.

    "We need furniture for our living room", says John Rose, "and we just didn't have enough money to buy it. So we decided to try to making a few tables and chairs."

    John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high. The Roses took a 2-week course for $ 280 at a night school. Now they make all their furniture and repairs around the house.

    Jim Hatfield has three boys and his wife died. He has a full-time job at home as well as in a shoe-making factory. Last month, he received a car repair bill for $420. "I was deeply upset about it. Now I've finished a car repair course, I should be able to fix the car by myself."

    John and Jim are not unusual people. Most families in the country are doing everything they can do to save money so they can fight the high cost of living. If you want to become a DIY, you can go to DIY classes. And for those who didn't have time to take a course, there are books that tell you how you can do things yourself.

    In the near future, daily newspapers and monthly magazines will probably disappear. Electronic media（媒体） can provide the same information faster and cheaper. The Internet, together with laptops and mobile phones, makes it possible that almost everyone can at any time and in almost any place get some news for free or for few fees.

    You'll browse the computer newspapers or magazines just like turning on TV. An electronic voice will tell you stories about the latest events. You'll even get to choose the kind of voice you want to hear. Want more information on the brief story？ A simple touch makes the whole text appear.

    There are the predictions from the experts working on the newspapers of the future. Imagined as part of home media and entertainment systems, computer newspapers and magazines would unite printed and broadcast news, offering information and analyzing video images of news events.

    The continuing loss of readers will lead to a small number of advertisements in newspapers. It makes no sense to spend millions of dollars to print ads.

    With the development of technology, more and more electronic media have been created until now, but replacing the traditional newspapers and magazines has a long way to go, because the resistance to computer newspapers and magazines from journalism（新闻业） may be much stronger. Since it is such a cultural change, it may be not until the present journalists（新闻工作者）, who aren't used to it, die off that the newspaper industry is not considered as an industry any longer. Anyway, technology is making the traditional newspapers and magazines disappear gradually.

    "Hope has proved a powerful predictor of outcome in every study we've done so far," said Dr. Snyder, a psychologist.

    In research with 3,920 college students, Dr. Snyder found that the level of hope among freshmen at the beginning of their first term was a more accurate predictor of their college grades than were their S.A.T. scores or their grade point averages in high school. "Students with high hope set themselves higher goals and know how to work to attain them," Dr. Snyder said. "When you compare students with equal learning ability and past school achievements, what sets them apart is hope."

    In seeking a way to assess hope scientifically, Dr. Snyder went beyond the usual belief that hope is merely the sense that everything will turn out all right. "This idea is not concrete enough; it fails to clarify two key components of hope," Dr. Snyder said.

    "Having hope means believing you have both the will and the way to accomplish your goals, whatever they may be."

    Despite the wisdom in the old saying "where there's a will there's a way," Dr. Snyder has found that the two are not necessarily connected. In a study of people from 18 to 70 years old, Dr. Snyder discovered: only about 40% of people are hopeful in the technical sense of believing they typically have the energy and means to accomplish their goals; about 20% of the people believed in their ability to find the means to attain their goals, but said they had little will to do so; another 20% have the opposite pattern, saying they had the energy to motivate themselves but little confidence that they would find the means; the rest had little hope at all, reporting that they typically had neither the will nor the way.

    "It's not enough just to have the wish for something," said Dr. Snyder. "You need the means, too. On the other hand, all the skills to solve a problem won't help without the willpower to do it."

Yosemite is a national park in California. It is very beautiful and big. The park includes more than 760,000 acres in the California Mountains. Most of the park is wilderness.

The part of Yosemite that everyone likes is Yosemite Valley. It is a tiny valley that is 7 miles long and less than 1 mile wide. It has tall rock walls and streams that splash down in waterfalls. More than two million visitors come to the valley each year.

One ranger (守护人) says the number of visitors is more than the land can handle. The valley has 4,500 camping spots. It has a hotel that can hold 4, 000 families. This is still not enough to handle all of the visitors. The valley has grown so big that it has a lot of traffic and crime.

A worker says the park is trying to keep the beauty of the park and let everyone visit. Some areas have been fenced off from people and planted with seeds to try to keep them beautiful.

A former worker thinks Yosemite should get more money to take better care of the park. He would also like to teach people what the park service is trying to do.

Some people are trying to save Yosemite Valley. A plan has been made to get rid of some buildings. There will be fewer cars allowed inside the park. More buses will help get people around.
