People in the western state of California who are in the United States illegally can now request a driver's license. The law went into effect on January l. California is not the first American state with such a law, but it has the largest number of illegal immigrants. More than a million people began to request licenses shortly after the new state law went into effect. Among them was Christian Alvarado. Mr. Alvarado entered the United States from El Salvador eight years ago without permission from the U.S. government. Some call such people "illegal immigrants." Others call them "undocumented immigrants".

    Mr. Alvarado thinks it so exciting, for he has been waiting for the license for a long time. But some are worried that their personal information will be used to find them and deport them. Armando Botello is a spokesman for the California Department of Motor Vehicles, or DMV. He says people should not be afraid, for such information will not be shared.

    The new licenses are the same as licenses given to citizens except that they have the words "Federal Limits Apply". That means the license cannot be used to travel on an airplane or enter a federal building. Ana Garcia, working at the Central American Resource Center, says some illegal immigrants fear those words will be used to abuse them. Civil rights groups say the police and others will not.

    Dan Schnur, a political scientist at the University of Southern California, said that the main argument against the new law is that it rewards illegal behavior. But Professor Schnur argued that young, white Americans generally support immigration reform, including giving driver's licenses to illegal immigrants

    "It's simply because they grew up in a much more multicultural society than their parents or their grandparents did." Professor Schnur says he believes the changes in beliefs about illegal immigrants that have taken place in California will spread throughout the United States.

    In today's world of smart phones and notebook computers, most people have at least one time-telling thing with them. Since these digital products are so common, is time running out for the 500-year-old watch? According to some consumers, the answer is yes. New Jersey teenager Charlie Wollman says a watch is “an extra piece of equipment with no necessary function.” Many young adults think so and use their smart phones to tell time. It is said that fewer young people wear watches today than ten years ago. As a result, some people say that the watch industry is at a crossroads.

    However, watchmakers optimistically say that watches regain popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality watch that doesn't just keep good time. Fifty years ago, watchmakers took pride in their products' accuracy. But in recent years, the watch industry has changed itself into an accessory(附属的) business. And today, the image a watch communicates has become more important than the time it tells.

    “Complications” — features that go beyond simple timekeeping — are an important part of a watch's image. Today's watches offer lots of features that meet almost any personality. These features include compasses, USB drivers, and even other functions .

    Creativity also plays a key role in designing today's watches. For example, Japanese watchmaker Tokyoflash makes watches that don't even look like watches. The company's popular Shinshoku model uses different color lights to tell time. It looks more like a fashionable bracelet(手镯) than a watch.

    Whether a watch communicates fashion sense, or creative talent of a love sports, consumers want their watches to stand out. Nowadays, everyone has the same kind of gadget(配件) in their bags, so people want to make a statement with what' s on their wrists. Will this interest in wrist fashion last? Only time will tell!

    How the Grand Canyon (大峡谷) was created remains one of the geology's greatest mysteries. Some evidence suggests that the process was a gradual one in which the Colorado River (which runs through the canyon) slowly cut deeper and deeper into the ground over millions of years. But volcanic rock samples taken from the canyon now suggest that the canyon was down-cut instead.

    Down-cutting is when a flood of water rushes over a landscape (地形) with enough force to cut deeply into the ground and leaves behind a canyon. Such a flood is usually released when a natural or man-made dam (堤坝) bursts.

    Robert Webb, a research geologist, says natural dams seem to have formed and broken across the Colorado River several times during the last million years. The dams were built when lava(熔岩) from the eruptions of nearby volcanoes flowed into the river. The lava hardened into hard rocks and blocked the river, causing it to back up and form a lake. Each time the lake grew so huge that it broke the rock dam, releasing a flash flood that furthered the down-cutting process and deepened the canyon.

    Down-cutting is not just an earthly event. Satellite photos sent back from Mars suggest that the process has happened there, too, say many other researchers.

    The photos, taken by the Mars Global Surveyor, indicate that an enormous lake existed on Mars 3.5 billion years ago. The lake spilled into a large nearby hole. One edge of the hole broke, releasing a flash flood that quickly carved out a grand canyon.

    The existence of down-cutting on Mars is just one more piece of evidence that the cold, dry planet was once warm and wet.

    A billionaire has recently made one of the biggest charitable（慈善的）donations to a university in China's history. Chen Tianqiao donated $115 million to the California Institute of Technology (Caltech) to help advanced brain research. The donation will be spent deepening the understanding of how the brain works. Chen has been interested in brain research, believing it can shape the industries such as artificial intelligence and virtual reality. However, this huge donation has caused heated discussions among Chinese scholars and internet users alike.

    Many criticized him for choosing to give money to a foreign university rather than home institutes for brain research, which are developing fast and are on track to catch up with the US in just a few years. Rao Yi, a biologist at Peking University, even said the donation was a typical mistake.

    Others, however, support his choice. They believe Caltech is a more reasonable choice compared with Chinese research institutions. Caltech has a long history and has taken a leading position in biology, and therefore it produces more efficient results. In addition, the results of the research benefit not only the American people, but also the rest of the world.

    A similar controversial case started two years ago when Pan Shiyi, chairman of SOHO China, donated $15 million to Harvard University to help disadvantaged Chinese students.

    Many believe that China is still behind in the management and use of donated money, and that as a result, Chinese charity donators are looking abroad. In comparison, Western countries like the US, which have a long history of donating money, have well-developed systems that use money efficiently. They can also provide full access for donors who want to track the use of the money. To get more donations, Chinese universities should be braver and more honest. They need self-reflection, rather than envy.

    Throughout history, artist, inventors, writers and scientists have solved problems in their dreams. Now, let's have a look together at some of them.

    ⒈Paul McCartney Found Yesterday in a dream

    Paul McCartney is one of the most famous singers/songwriters of all time. According to the Guinness Book of Records, his Beatles song Yesterday(1965) has the most cover（翻唱） versions of any song ever written and, according to record label BMI，was performed over seven million times in the 20^th century.

    The tune for Yesterday came to Paul McCartney in a dream.

“I woke up with a lovely tune in my head. I thought, 'That's great, I wonder what that is?' There was an upright piano next to me, to the right of my bed by the window. I got out of bed, sat at the piano, found G, found F sharp minor—- and that leads you through then to B to E minor, and finally back to E. It all leads forward logically. I liked the melody a lot, but because I'd dreamed it, I couldn't believe I'd written it. I thought, 'No, I've never written anything like this before.' But I had the tune, which was the most magic thing! ”

    ⒉Mary Shelley's Frankentein Inspired by a Dream

    In the summer of 1816, nineteen-year-old Mary Wollstonecraft Godwin and her lover, the poet Percy Shelley (whom she married later that year), visited the poet Lord Byron at his villa beside Lake Geneva in Switzerland. Stormy weather frequently forced them indoors, where they and Byron's other guests sometimes read from a volume of ghost stories. One evening, Byron challenged his guests to each write one themselves.

    Mary's story, inspired by a dream, became Frankentein（科学怪人）.

“When I placed my head upon my pillow, I did not sleep, nor could I be said to think—-My eyes shut ,I saw——with my acute mental vision—-the pale student of unholy arts kneeling beside the thing he had put together. I saw the ugly figure of a man stretch out, and then, on the working of some powerful engine, show signs of life, and tremble with an uneasy motion, extremely frightful. The next morning I announced that I had thought of a story. I began that day with the words, 'It was on a dull night of November', making only a transcript(文字稿) of the cruel terror of my waking dream.”

Dear Max,

It must seem a little odd to get a letter from your own mother who m you see every day, but I hope you will read this and take what I have to say seriously. 

I bought you a phone for your 12th birthday because you wanted one so much, and all your friends have one. I know you love your phone, but I wonder whether you are aware of just how much you use it. 

From my perspective, it seems that you are constantly checking your phone for notifications（通知） or messages. You even do this when we're having a family meal in a restaurant or when I'm talking to you. You may not realise this, but whenever you feel even slightly bored, you check your phone. You never seem to relax. You're constantly on alert, and I don't think this is very good for you. We all need to switch it off every now and then. And if I ask you to leave your phone at home when we go out, you sulk（生气） and get twitchy, almost as if you're suffering withdrawal symptoms（戒断症状）. It's like your phone is a drug.

I have tried to talk to you about this, but whenever I ask you to put down your phone and look at me, you say "in a minute". Unfortunately, "in a minute" never comes, and we never talk. I can't actually remember the last time we had a proper face-to-face conversation. I even have to message you to let you know dinner is on the table! That's why I decided to put my concerns in a letter to you.

Please don't think I am writing this letter to punish you or to nag（唠叨） you. I know you are a good boy. I don't think you want to hurt me or be rude intentionally. However, I recently heard about something called "nomophobia"—the fear of being without a phone. It's a real illness and I'm worried whether you have it. I really think it would be a good idea if we all went to see an addiction expert together so we can all have a discussion about this serious problem. I know you won't want to, but I'm very concerned about you. Please take some time to think about what I have written. Then let's talk.

Mum,
