    In the tenth grade，I began working for free at a vet's that was run by a friend. I wanted to get experience for what I thought would be my future job. However，on one particular Saturday morning I learnt something perhaps more important.

    The hospital was in the middle of one of the poorer sections of the city and some people could only pay for the most basic treatments. On this Saturday，a man and his young son，who was probably about 7 years old，walked in with a small cat in a cardboard box. There was something wrong with the cat's left eye. But the man could not afford to pay for the cost of the medicine. He kept quiet for a while，and then he asked where the nearest animal shelter was. Hearing this，his son cried and started to argue with him. All of a sudden，an older woman who was sitting in the waiting room stood up，walked up to the counter，and told the man that she would pay for the cost. The man thanked her and the son got to keep a healthy cat.

    I always thought it was the right thing to help out a needy person，but I only saw people do acts of kindness on TV or in movies. What the woman did made me believe that these things do happen in real life，and quite often.

Now，when I can't decide whether to help someone who is in need，I remember this woman，and then I have the courage to step up to the plate. Sometimes other people follow.

The Handshake

    I don't remember the exact date I met Marty for the first time. Like a lot of people who want to get through a checkout line, I found my thoughts on speed, nothing more. The line I was standing in wasn't moving as quickly as I wanted, and I glanced toward the cashier, who was receiving money from customers.

    He was an old man in his sixties. I thought, well, it probably took him a little longer to get the jobs done. For the next few minutes I watched him. He greeted every customer before he began scanning the goods they were purchasing. Sure, his words were the usual, “How's it going?” But he did something different—he actually listened to people. Then he would respond to what they had said and talk with them briefly.

    I thought it was strange, but I guessed I had grown accustomed to people asking me how I was doing simply out of a conversation without thinking. Usually, after a while, you don't give any thought to the question and just say something back quietly.

    This old cashier seemed sincere about wanting to know how people were feeling. Meanwhile, the high-tech cash register rang up their purchases and he announced what they owed. When customers handed money to him, he pushed the appropriate keys, the cash drawer popped open, and he counted out their change.

    Then magic happened.

    He placed the change in his left hand, walked around the counter to the customers, and extended his right hand in an act of friendship. As their hands met, the old cashier looked the customers in the eyes. “I want to thank you for shopping here today,” he told them. “You have a great day. Bye-bye.” The looks on the faces of the customers were priceless.

    Now it was my turn. I glanced down at the name tag on his red waistcoat, the kind experienced Wal-Mart cashier wore. It read, “Marty.”

    Marty told me how much I owed and I handed him some money. The next thing I knew he was standing beside me, offering his right hand and holding my change in his left hand. His kind eyes locked onto mine. Smiling, and with a firm handshake…

    Should you work out in the gym in the morning instead of in the evening? It all depends. Of course, there are advantages of working out(运动) in the morning.

    You will increase your energy for the rest of the day. “Morning workouts result in better energy levels throughout the day and give you more mental sharpness,” says Dr. Cedrie Byrant, Chief Science Officer of the American Council on Exercise.

    Here is another advantage. In 2017, health researchers found that exercising in the morning helps you sleep better at night. According to the study, in all cases, those who exercised at 7:00am experienced about a 10 percent drop in blood pressure that carried through the rest of the day. They also had about a 25 percent drop in blood pressure at night, slept longer and had more beneficial sleep cycles than when they exercised at other times of the day.

    However, there are disadvantages, too.

    If you are not an early riser, getting out of the bed in the morning can be very difficult. Byran says that if you're not used to exercising in the morning and force yourself to get up, you may not put as much effort into the exercise as you would later in the day. Also, if you aren't careful, you can damage your sleep schedule, which can lead to insufficient sleep.

    Besides, hitting the gym before work can cause a challenge in terms of scheduling. If you work a 9-to-5 job, getting ready for work and going to work can cut your morning workout short, Byrant notes.

    To sum up, it has both advantages and disadvantages. If it suits you better to work out in the morning, you can do so.

    Whenever I talk about personality (个性) in relation to choosing a career, someone always complains like this: those tests are so stupid. When I was in the sixth grade, I took one of them and it said that I should be a farmer. While I don't think I would be a very good farmer, the results are probably a lot more accurate (准确) than I'd like to admit. At the time, it seemed ridiculous­I hated the outdoors and physical work, and was particularly sick of being dirty or sweaty. Now, though, as I think in terms of personality, it might have had something to do with my personality: I like long­term planning, working by myself, and being the master of my own fate.

    Personality tests are various, and some are complete nonsense. Be careful of any personality test that claims to be capable of concluding what your dream job is from your favorite food for breakfast, or by the type of animal you like best. While there are many personality assessments (评估) that are very accurate, I'd love to say that they are a second (and often expensive) step. The best choice is to find out about yourself for yourself.

    Before determining the ways to examine your work preferences, it's important to know the difference between liking a topic and liking the work. I once had a young guy who was a third­year marine (海洋的) biology student at a large state school in Ohio. He applied for and was placed into the Whale Watch program, where he found out that he became terribly seasick on any kind of boat­a big disadvantage for a student who thought he wanted to study whales in the wild.

Lisinopril

    What is lisinopril? Lisinopril is a medicine to treat high blood pressure. This medicine is only available on prescription. It comes as tablets. It also comes as a liquid for people who find it hard to swallow tablets, but this has to be ordered specially by your doctor.

    Important information

    To make sure lisinopril is safe for you, tell your doctor if you have:

    Heart, liver or kidney problems

    Diabetes (糖尿病)

    Higher levels of potassium (钾) in your blood

    Women who are pregnant can't take the medicine. It could harm the unborn baby.

    How should I take lisinopril?

    Take lisinopril exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may sometimes change your dose (剂量) to make sure you get the best results.

    Drink plenty of water each day while you are taking this medicine.

    Lisinopril can be taken with or without food.

    Your blood pressure needs to be checked often, and you may need frequent blood tests.

    What if I forget to take it?

    If you miss a dose of lisinopril, take it as soon as you remember. If you don't remember until the following day, skip the missed dose. Do not take a double dose to make up for a forgotten one. If you forget doses often, it may help to set an alarm to remind you.

    What should I avoid while taking lisinopril?

    Avoid drinking alcohol, because it can further lower your blood pressure and may increase certain side effects of lisinopril.

    Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

So far this winter, a theater in the Alps has staged more than 60 unique concerts. Winter temperatures in the remote mountain village can drop high below zero. Performers wear down jackets and play ice instruments. In fact, almost everything from drums and guitars to horns and harps at the music festival is carved from ice even the stage the musicians play on. The audience sits on ice chairs and benches and claps their hands to listen, both to praise the performers and to keep themselves warm when the air flows through.

The musical instruments used were almost entirely made by an American ice artist, Tim Linhart. Since he created his first musical instrument out of ice more than a decade ago, he has already carved various ice instruments, including violins, violas, timber drum sets, xylophone, double bass, mandolin and cello. He also created his own large wind instrument, which uses the vibration of an ice tube to produce sound when the air flows through.

Linhart makes the different parts of the ice instrument and then uses a liquid mixed with snow to glue them together, with a metal support placed where the strings need to be. A violin can usually be made in two or three weeks, while larger instruments can take more time and efforts, sometimes taking months to make.

An ice instrument has a clearer sound than a wooden instrument. However, ice instruments are more easily broken or damaged than ordinary instruments. The temperature in the ice theater changes depending on the number of people in the audience. This also changes the temperature of the ice instruments, which in turn affects the 1 sound they produce. Musicians need to tune their instruments frequently during performances.

Although playing an ice instrument is not easy, Linhart believes that ice and snow are good materials for making instruments. The only downside is melting when the temperature is above freezing.
