Sound travels very well through water-much better, in fact, than it does through air. So it shouldn't be surprising that many ocean animals make noise. They use sound to communicate and hunt. As biologist Brandon Southall says, “Their whole world is related to sound.”

    Dolphins whistle, organizing hunts. Lovesick whales sing so loudly they can be heard hundreds of miles away. But these days they aren't the only ones sounding off. They have more and more competition from human machines.

    Every day, thousands of huge container ships sail across the world's oceans. On top of the engine noise, the ships' propeller (螺旋桨) make a loud noise all the time. All that can make it hard for ocean animals trying to listen out for friends, or dinner. Animals swimming nearby a ship can be deafened or even killed.

    Underwater construction can also be dangerously loud. When construction machines called pile drivers were used during repairs to the San Francisco-Oakland Bay Bridge, dead fish appeared.

    Geologist (地质学家) pound on the seafloor too, trying to find oil wells and map Earth's surface. The results are useful lo science, but all that hammering probably gives ocean animal a headache.

    As people realize how important sound is to ocean animals, they are looking for ways to reduce human noise. Ships could get quieter just by slowing down. Engineers are also trying to find quieter propeller ships.

    Now some companies are using a simple invention called a bubble curtain, which makes sound waves passing through it lose energy and gel quieter. It seems to work - when bubble curtains were fixed on the San Francisco bridge project fish deaths dropped.

    We still have a lot to learn about sound in the oceans, but together we can help keep the sea a quieter place.

It is OK not to be OK

    This is the simple encouragement people often use for themselves or others. But for professional athletes, this can be the hardest sentence to say.

    On March 6, Cleveland Cavaliers forward Kevin Love posted an article titled “Everyone is Going Through Something” on the website The Players' Tribune. In the article, the 29-year-old showed how he suffered from his first panic attack on Nov 5 in a game against the Atlanta Hawks and why he was so worried about sharing his story with the public.

    Love identified that what keeps people from speaking up about their mental health challenges is the fear that many people see them as a weakness. “Growing up, you figure out really quickly how a boy is supposed to act. You learn what it takes to 'be a man'. It's like a play book: Be strong. Don't talk about your feelings. Get through it on your own,” he wrote.

    And being an NBA player made his situation even more difficult. Love was afraid to share his struggles because he didn't want his Cavaliers teammates to think that he was unreliable.

    However, as it turned out, Love's teammates understood and supported him. Cleveland superstar LeBron James even wrote on social media that Love is “even more powerful now than ever before”.

    For Love, it was a journey of empowerment to accept and address his mental illness and share his experience with millions of people who face the same problems. In fact, he was inspired to talk about his situation by Toronto Raptors shooting guard DeMar DeRozan, who had also opened up about his mental health issues.

    Last month, the 28-year-old told the Toronto Sun that despite being a top-performing and wealthy NBA player, he still deals with constant blues. “It's one of the things that no matter how indestructible (坚不可摧的) we look like we are, we're all human at the end of the day, ”he said. “Sometimes…it gets the best of you, when everything in the whole world's on top of you, ” But other times, by admitting who we are, we can get what we want. As Love told Advance Ohio Media, “You have to let some of that stuff bleed out in order to fully recover from it.”

    With Disney parks recently raising their ticket prices to $89 now is the perfect time to start thinking about smaller, regional theme parks. Here are four theme parks where the daily price of adult admission is under $50.

    Luna Park, Coney Island, NY.

    How much you spend in enjoying Luna Park really depends on which rides you choose to go on. For anyone as indecisive as I am, stick with the $29 four-hour Unlimited Luna Park Ride Wristband or the $39 Ride and Play package, a four-hour unlimited ride wristband that comes with a $20 game card.

    Dorney Park, Allentown, PA.

    Dorney Park is a popular theme park located about an hour outside of Philadelphia. Kids love Planet Snoopy, a fun area with attractions centered around the lovable Snoopy. Adult tickets are available online for $39.99 (or at the gate for $49.99) and kids are $27.99 online or ($29.99 at the gate). You can also buy a Starlight Admission ($27.99 online or at the gate), good for visits between 5 p.m. and 10 p.m. during the summer months when the park is open late, or from 3:30 p.m. to 8 p.m. when the park closes earlier.

    Knotts Berry Farm, Buena Park, CA.

    Home to some of the country's craziest rides, Knotts Berry Farm also has calmer, more family-friendly rides. Ages 12-61 get in for $39.99 when tickets are bought online, while children ages 3-11 and adults over 62 pay $26.99.

    Santa Cruz Boardwalk, Santa Cruz, CA.

    Sitting on the warm beaches of Santa Cruz — about 90 minutes south of San Francisco — the Boardwalk is home to big roller coasters, mini-golf, enough food and games to keep people of all ages busy. The best part? An all-day unlimited rides wristband is only $31.95.

    A newspaper reporter's job can be very interesting. He meets all types of people and lives quite a busy life. He is on the rush for news all the time, then after several years he may get a desk job, and life becomes a bit more settled. Let's look at his work a little more closely. In a day he may have to interview the prime minister of a foreign country, and the next day he may be writing about a football match. Sometimes he may be so busy that he has hardly any time to sleep. And at other times he may go on for days looking out for news materials yet return empty-handed.

    In the beginning, a reporter has to cover a very wide field. After the early years he becomes more specialized in his work. For example, he may finally be asked to write only on court cases or politics or sports. Some reporters may become so specialized that they are asked only to write on a special thing: horse racing, for example. In most newspaper houses there is at least one special racing correspondent. Some newspapers have book reviews. Their job is delightful. They read the latest book and then write reviews on the ones they like. Then there are those who write on films, so they get to see them even before they are shown in the cinema. How lucky, you would say!

    A reporter's job can also be very dangerous. A number of them have died rushing from one assignment to another, and if there is a flood or a riot(暴) they may get hurt or even be killed. Three years ago there was a reporter whose camera was smashed by a group of men, because they were angry with him for taking their picture. Dangerous or not, one thing is certain, and that is, their job is never dull!

Living a healthy lifestyle lies in forming the right eating habits. Here are some of the good habits you can develop when it comes to healthy eating.

Drink plenty of water, you must drink at least 8 glasses of water a day. You may need even more water if you are in a hot environment or if you are exercising.

Eat breakfast. Breakfast is the most important meal of the day. A recent study has shown that those who eat breakfast will use an average of 100 calories less during the day than their colleagues who skip breakfast. They will also be able to concentrate better.

Don't skip lunch. If you do so, your blood sugar level will drop and your metabolism (新陈代谢) will slow down. When you get home you are starving and eat everything you can find.

We all need to snack from time to time, but please choose your snacks carefully. In fact, it's a good idea to eat two healthy snacks besides your three main meals. Choose healthy snacks like fruits, low fat yogurt, cottage cheese with apple sauce.

Eat your fruits and vegetables. We should eat at least 5 servings of fruits and vegetables a day. Take a piece of fruit for a snack, add some bananas and raisins to your favourite breakfast cereal (谷类食物), have a salad of lunch, and eat at least one vegetable at dinner each night.

Do not eat your dinner too late. Try to eat dinner at least 3 hours before you go to bed, this will give your body a chance to digest most of the food before you rest for the next 8 hours. Plan dinner for the week ahead of time and make sure you have everything you need in the house so other family members can get ahead start on dinner if you have a late meeting at the office.

The term "SMART goals" was coined by in 1954. Since then, SMART goals have become popular with business managers, educators and others because they work. The late management guru Peter F. Drucker developed the concept. Drucker shaped many top managers' career. Management by objectives was one of his primary business theories.

In 2002, Drucker received the highest civilian honor in the U.S.—the Medal of Freedom. He died in 2005 at age 95. Drucker's family decided to look forward instead of backward, and they gathered distinguished business people to form The Drucker Institute.

The institute's website states ""Their work is to transform the archival (档案) treasure into a social enterprise whose purpose is to strengthen society by encouraging effective, responsible and joyful management."

If you have been to a business management class, you may likely have learned how to write goals and objectives in Drucker's way: SMART. If you haven't heard about Drucker, you are in for a treat that will help you achieve what you want and be more successful, whether you are a teacher trying to teach well, an adult learner or a person who seeks to achieve your dreams.

SMART goals are: "s" stands for specific. Make your goal or objective as specific as possible Say exactly what you want to achieve in clear, concise words. "M" stands for measurable. Include a unit of measure in your goal. Be objective rather than subjective. When will your goal be achieved?

How will you know it has been achieved? "A" stands for achievable. Ensure that your goal is feasible in terms of the resources available to you. "R" stands for realistic. Focus on the end results you desire rather than the activities necessary to get there. You want to grow personally, so reach for your goal—but be reasonable or you'll set yourself up for disappointment. "T" stands for time-bound. Give yourself a deadline within a year. Include a timeframe such as a week, month or year, and include a specific date if possible.
