    About three hours after Hurricane Harvey made landfall in Texas as a Category ( 级 别 ) 4 storm, it was downgraded to a Category 3 storm after winds decreased to 125 mph from maximum winds of 130 mph.

    Harvey also made a second landfall on the northeastern shore of Copano Bay around the time it was downgraded.

    The storm is the strongest to hit the state in decades, with serious flooding expected. The last Category 4 storm to hit the U.S. was Charley in 2004 in Florida, while the last Category 4 storm to hit Texas was Carla in 1961.

    Residents staying in the area madly stocked up on(备足) food, water and gas, while others heading out of the storm's path boarded up windows and doors of their homes and businesses.

    Airlines canceled flights, schools were closed while concerts and other planned events in Houston and coastal cities were postponed.

    The hurricane's effects are expected to last for days, with heavy rainfall through next week estimated to be as high as 40 inches in some areas.

    The National Weather Service warned Harvey could bring a potentially destroying storm surges( 风 暴 潮 ), heavy rainfall and wind hazards( 危 害 ) to the Lone Star State's coast. A tornado watch is in effect for areas of southeastern Texas and southwest Louisiana.

    Life-threatening storm surge waters could reach 9 to 13 feet above ground level. Destroying flooding is expected across parts of the area. And rainfall will be heavy, with an estimated 15 to 30 inches of rain falling in many areas and as high as 40 inches in some from today through Wednesday, the National Weather Service said.

    You have probably heard the saying,"When life gives you lemons,make lemonade."Since lemons are considered bitter and lemonade is considered sweet,the saying tells you to make the best out of a bad situation.

    Unfortunately,when something bad happens,it's not uncommon for most people to talk about it to anyone who'll listen,and complain about life,"Why me?"That's like getting a bag of lemons,putting them down,and thinking, "Lemons taste bad!I'd rather have chocolate!"If you don't make anything with the lemons,they will go bad.But what if you did something with them?What if you made lemonade?Isn't it possible to do something similar with a bad situation?

    Here's an example.Let's say you're about to go to the movies,but you discover you have a flat tire（瘪胎）.You consider this a terrible thing. After all,you are really looking forward to spending some time with Ryan Gosling and Emma Stone.Now you're all stressed out,hating the tire,the car,and your life.But what if you called AAA,got your tire fixed or got caught up on things that you'd been meaning to do?What if you did some reading,or had coffee with a friend instead?A negative experience can be turned into something positive.Almost anything can work itself out into something better.You can't change what has happened,right?So make the best of it.I'm not saying it will be easy. The easy thing to do is complain about your bad situation and not consider what it could be turned into.

    Next time when some unfortunate things happen,stop and think,"How can I turn this around?How can I make it a positive experience?You needn't fear difficulties.As long as you keep on changing it,you will see the benefits（好处）at last.

    A psychologist walked around a room while teaching stress management to the audience. As she raised a glass of water, everyone expected they'd be asked the “half empty or half full” question. Instead, with a smile on her face, she inquired. “How heavy is this glass of water?”

    Different answers are called out from the audience.

    She replied, “The absolute weight doesn't matter. It depends on how long I hold it. If I hold it for a minute, it's not a problem. If I hold it for an hour, I'll have an ache in my arm. If I hold it for a day, my arm will feel numb and paralyzed. In each case, the weight of the glass doesn't change, but the longer I hold it, the heavier it becomes.”

    She continued. “The stresses and worries in life are like that glass of water. Think about them for a while and nothing happen. Think about them a bit longer and they begin to hurt you. And if you think about them all day long, you will feel paralyzed and be incapable（无能力的）of doing anything.”

    It's important to remember to let go of your stresses. As early in the evening as you can, put all your burdens down. Don't carry them through the evening and into the night.

    Remember to put the glass down!”

    Short but valuable! It clearly teaches me how to deal with stresses.

    Wow! Thank the author and the one who submitted the article. I am experiencing a challenge when I read this. It gives me peace. What exactly is in the article is what I am doing. My burden actually paralyzes me without my knowing it. I put down the glass of water that I am holding. Thank you so much!

    Gravity signals that race through the ground at the speed of light could help seismologists(地震学家) get a better handle on the size of large, destructive quakes soon after they hit，a study suggests. The tiny changes in Earth's gravitational field, created when the ground shifts, arrive at earthquake monitoring stations well before earthquake waves.

    “The good thing we can do with these signals is have quick information on the magnitude (震级) of the quake,” says Martin Vaillée, a seismologist at the Paris Institute of Earth Physics.

    Earthquake equipment in China and South Korea picked up gravity signals immediately after the magnitude-9. 1 Tohoku earthquake that destroyed parts of Japan in 2011. The signals appear as tiny accelerations on earthquake-recording equipment, more than a minute before the seismic waves show up.

    “We can look before the earthquake waves arrive,” says Vallée. “If we see nothing, we can say that the quake that made these was maybe large, but not huge. If we see the signals, it means we really have a very big quake. ”

    Had seismologists been monitoring for gravity changes, they might have realized sooner just how big the Tohoku earthquake was. A small increase in an earthquake's magnitude means a large change in the energy released by the quake-and the destruction expected. That information is important for emergency responders as they decide what resources to arrange.

    It'll be a major contribution if gravitational waves can beat down the time needed to know that a big earthquake is big. But much work remains before gravity signals can be considered a reliable tool in the vital minutes after a big quake. A few extra minutes of warning can save lives, particularly in coastal areas where people can flee ahead of an incoming tsunami.

    When asked about her childhood in the documentary Alive Inside, a 90-year-old woman with dementia(痴呆) replies, "I've forgotten so much." Filmmaker Michael Rossato-Bennett then plays music from her past for her. “That's Louis Armstrong,” she says. “He's singing When the Saints Go Marching In and it takes me back to my school days.” She then recalls exact details from her life.

Why does it happen? Music tends to accompany events that arouse emotions or otherwise make strong impressions on us — such as weddings and graduations. These kinds of experiences form strong memories, and the music and memories likely become intertwined(紧密相连) in our neural(神经的) networks, according to Julene Johnson, a professor at the University of California. Movements, such as dancing, also often pair with our experience of music, which can help form memories. Even many years later, hearing the music can bring back memories of these long-past events.

    As Alive Inside shows, music has this power even for many people with dementia. Researchers note that the brain areas that process and remember music are typically less damaged by dementia than other areas, and they think it may explain the phenomenon.

    They also pay attention to elderly people with dementia, especially those in nursing homes. "It's possible those long-term memories are still there," Johnson says, “but people just have a harder time accessing them because they're in a strange place and there are not a lot of circumstances in which someone could pull out those memories.”

    Johnson also notes that music is not universally useful for all people with dementia since there are some people with dementia whose brain area that recognizes music is damaged.

    Despite music's apparent benefits, few studies have explored its influence on memory recall in people with dementia. “It's really an untapped area,” Johnson says. Petr Janata is one researcher investigating the topic of music and memory. He says that scientists still do not have the answers for why and how music reawakens memories in people with dementia, but this phenomenon is real and it's just a matter of time before it's fully borne out by scientific research.
