(Reuters) - The search for missing Malaysia Airlines Flight MH370 is likely to drag on for years, a senior U.S. defense  official told Reuters on Friday, as an underwater search for any trace of the plane off west Australia appeared to have failed.
The official, speaking under condition of anonymity(匿名)because he was not authorized to comment on the search effort, said two weeks of searching the Indian Ocean floor with a U.S. Navy had turned up no wreckage(残骸).
He said the search for the plane, which disappeared on March 8 with 239 people on board, would now enter a much harder phase of searching broader areas of the ocean near where the plane is believed to have crashed.
”We went all-in on this small area and didn't find anything.  Now you’re got to go back to the big area," the official said.  "And now you're talking years.”
On Friday, the undersea drone. Bluefin-21 is expected to finish what may be the last of its 16-hour trips to depths of  more than 4.5 km (2. 8 miles) searching a 10 square km (6.2 square mile) area of the seabed about 2,000 miles northwest of Perth.
Authorities had identified the area as their strongest lead in determining the plane's final resting place after detecting what they suspected was a signal from the plane's black box recorder on April 4.
But the U. S.  official said Malaysia would have to decide how to continue the search, including whether to bring in more underwater drones,  even with the understanding that the search could continue for years without a refined (精确的) search area.
What does the passage mainly talk about?  ( no more than, 12 words)
                                                                            
Where did the recent search for the plane take place? ( no more than, 3 words)
                                                                            
Why didn't the official want others to know his name? ( no more than 11 words)
                                                                            
What led people to determine the plane's final resting place? ( no more than 9 words)
                                                                            
According to the passage, which country is in charge of the arrangement of the search? (1 word)

Have you ever intended to be fully absorbed in your work but found yourself distracted by e-mail, the Internet and other things throughout the day?
"People often lose their concentration when they are bored, of course, but also when they are engaged in challenging tasks," says Peter Bregman. "They sometimes have a feeling to escape from what's difficult or boring, so they jump out," he says. The part of the brain devoted to attention is connected to the brain's emotional center. Any strong emotion—quarrels with colleagues, problems at home—can interrupt our attention. Studies over the last decade have shown that too much work to do at a time can easily lead to distraction.
Refocusing is hard for many people. Robert Epstein suggests the following, "Stop and listen to music for a few minutes. Go for a short walk or take a deep breath, where you breathe in deeply, count to five slowly, hold it and breathe out very slowly." This can "blow out all the tension and the unwanted in your mind to restore your focus."
Take more control by structuring your time and becoming more aware of your behaviors. "Setting the phone alarm to go off every hour is my way of creating awareness," Mr. Bregman says," You have to inform yourself that you've lost focus in order to do something about it." Starting the day with a to-do list is important, such as when to eat, when to go to the gym or take a walk. But if it's overly ambitious, you will put yourself in a state of anxiety, which makes it hard for the brain to concentrate. "Choosing three or four things as your priority for the day allows your brain to settle down and focus," he says.

Society is a web of relationships, requiring all parties(群体) to work together to create something good. What makes society work best are effective(有效的) relationships that are based on mutual(相互的) understanding. If you understand what people want and why they want it, you can usually find a way to make progress together.
High-quality relationships make people happy. Some people living in the poorest communities have almost nothing but turn out to be the happiest because they share a life, together. If effective relationships are working, happiness is always possible.
Here are some simple tips for building effective relationships.
Listen to and try to understand others' positions and feelings. Listening in itself can lead to understanding, and if you understand someone else fully, then you know how to work better with him or her.
Openly express your needs and feeling. Sometimes we expect people particularly those close to us at home or work to understand what we want and to give us what we need intuitively (凭直 觉地). However, people are so complicated and so different that even when they have lived together for 60 years, they can still surprise each other. So we need to say what we need and to express how we feel.
In order to make our relationships more effective, we should treat ourselves and other people with respect. Respect is one of the most important elements of any good relationship.
Finally, learn to face differences correctly. Learning this takes time and can be uncomfortable. However, if we can try to remove differences in an effective way, we are more likely to build exciting and satisfying relationships with others.
By doing these things you may discover that the happiness you long for is much closer than you thought.

Scientists, doctors and mental health professionals have been studying the connection between colors and mood for years. Many now believe that colors can not only bring about emotional reactions, but can also correct mood. Colors behave in three basic ways: active, passive and neutral (中和的).
Active colors are warm colors, including yellow, orange and red. These colors bring confidence. Warm colors can also bring cheerful attitudes. Yellows and golden colors work well in offices, kitchens and study areas. Reds heat up a room. Passive colors or cool colors make people calm, quiet and satisfied. Bedrooms, private areas and bathrooms are great places for blues and greens. Beige, gray and white are thought of as neutral colors. They help to put the focus on other colors or serve to tone down colors that might otherwise be overpowering on their own.
You can easily change the look or feel of a room by making good use of different colors. Mixing and matching colors is an excellent way to balance color and emotion, and provide a welcoming feel for guests.
To create a feeling of warmth and comfort in a room, use bright, warm colors like yellow, orange and red. These colors are good choices for rooms that appear cool due to limited sunlight. Yellow adds cheerfulness to dull rooms. You can add yellows to rooms which are not closely related to happy thoughts, such as kitchens and laundry room. In rooms where there's plenty of sunshine, cool colors can provide a calming environment. Sage greens and sky blues are perfect for bedrooms, playrooms and activity areas. Neutral colors, such as pale gray, white and beige, send a peaceful message to your brain. It's not a coincidence that most doctor's offices, coffee shops and mental health centers are decorated in neutrals.
To make your wall color choices better, pick out furniture that will provide a visual contrast. Cool colors make a room seem larger than it is and warm colors make rooms feel smaller.

A scientist once said that studying the stars from the earth is something like looking up at the sky from the bottom of a swimming pool. Even on the clearest night the earth’s dense atmosphere will dim stars in the sky as it screens out (遮挡) 30 percent of their light. Air turbulence (湍流) causes stars to winkle. Through a telescope, the stars seem to jump around dizzily.
Because the moon has no atmosphere, astronomers are looking forward to setting up an observatory there. On the moon, there will be no clouds to obscure the view. The sky will appear dark at all times, so astronomers can work twenty-four hours a day. Because there is not air turbulence, the stars will steady through a telescope.
Because the moon is relatively near the earth, moon-based astronomers will see the stars in familiar patterns known on earth. They will not need new star maps of the sky. Stars seen from the moon will appear to move very slowly. Because the earth rotates (自转) on its axis once every twenty-four hours, earth-based astronomers see the stars hurry across the sky each night. The moon rotates on its axis only once a month. To astronomers on the moon, the stars will appear to stand almost still. Moon-based astronomers will have much more time to focus their telescopes and take time ---exposure photographs.
On the earth, man-made radio noises jam the airwaves and interfere with the reception of radio signals from certain stars. A radio telescope located on the far side of the moon will be permanently protected from such interference.
It won’t be easy to put telescopes on the moon. However, astronomers are certain the job can be done. They are convinced that the moon is an ideal place to set up an observatory.
