Retired nurse Sue Collins was just beginning the second length of her local pool when her morning swim suddenly became anything but a pleasure.

    Two months ago Sue, 69, who has never suffered from asthma or any other breathing problem in the past, suddenly found herself hard for breath.

    “I felt as if my throat and oesophagus (食道) were closing up,” says Sue.

    Sue is convinced the problem is related to the indoor swimming baths. “I spend half the year in Turkey and swim every day outside in a pool or the sea there and never have this problem,” she says.

    She may be right, because although a trip to the pool is the perfect exercise for many, the chlorine (氯气) used to keep the water free from germs can lead to problems.

    But in most cases it's not the chlorine that causes problems, but the by-products formed when chlorine interacts with other substances — and this is mostly due to people not showering before they enter the pool.

    “This then poisons the water for them and for others,” says Dr. Hull. “The chlorine interacts with sweat and urine(尿素) on the skin and forms by-products called chloramines that float above the surface as a gaseous solution that can be inhaled in.”

    Chloramines are heavier than air so hang over the water where they are easily breathed in. Some believe they may cause lung disorders. A Swedish study in 2013 examining the health of 146 workers at 46 indoor pools found that 17 per cent had airway trouble at work — but no problems at home.

    As Dr. Hull says: ‘People need to remember that showering isn't just for them. It is for the greater good.'

    You may have seen a talking parrot on a TV show, in a movie, or even in someone's home. The parrot has learned to copy sounds that people make. Birds are not the only animals that can copy the noises they hear. Dolphins, bats, and some apes also copy sounds. Now we can add elephants to this list of copycats.

    Dr. Joyce Poole is a zoologist. She studies the sounds of elephants. While she was in Kenya, she would hear strange noises made by Mlaika after sunset. Mlaika was a 10-year-old African elephant.

    Mlaika lived near a highway. Dr. Poole says, “I could not tell the difference between Mlaika's call and the distant truck noise.” She and other scientists studied Mlaika's sounds. It turned out that Mlaika was copying the sounds of the trucks driving by. Why would Mlaika copy trucks that she heard going by on the highway? Animals that are able to copy sounds may enjoy practicing new sounds. When they are kept outside of their natural environment, they may copy unusual sounds. That may be why an elephant would copy the sound of a truck.

    “Mlaika was not the only copycat elephant,” Dr. Poole says. Calimero is a 23-year-old male African elephant. He spent 18 years with two female Asian elephants. Asian elephants make chirping sounds (sounds made by birds) to talk with one another. African elephants usually do not make chirping sounds. But Calimero now does. He is copying his Asian elephant friends. Dr. Poole says that elephants need to form bonds with their family and friends. She says, “They make sounds to communicate with each other. When they are separated, they use sounds to keep in contact.”

    Parrots, dolphins, humans, and elephants show that being a copycat is one way that animals and people make new friends and keep old ones.

    I recently posted a picture on Facebook from the movie Mad Max, a film where two groups race through the desert in steampunk vehicles, and wrote, “Actual picture of my way to work today.” It was meant to be a joke because of the sandstorms in Beijing, but one of my friends from back home thought it was real.

    I couldn't imagine how they could think that is actually what China is like. China has so many more conveniences and advantages than the West, and many of my friends agree. “I don't know how I will be able to deal when I go back home,” said a friend who is about to end her gap year in Beijing. “I've become so spoiled in China.”

    China seems to be leading the way in innovation(创新) and convenience for daily life. Back home I could never shop, pull out my phone and scan a QR code to pay.

    There have been rumors of starting bike sharing in my hometown for years with little success while bike sharing suddenly appeared in Beijing overnight. I just step outside and scan a code, and I am on my way.

    Going out to eat with a group of friends back home was troublesome for both the group and the servers. Splitting bills and swiping(刷) 10 different cards or making change for each person in the group can be a pain. But with China's WeChat, you can quickly send your friends your part of the bill.

    The list goes on…

    When I first arrived in Beijing, I was dead set on leaving in a month. That month has come and gone. Now, when someone asks me when I'm coming back, I think to myself, “Who knows?”

    While my friends think I am riding through the desert on a motorbike, I am actually taking a Didi for what is the equivalent of $5 in the US.

    With all the conveniences and technology here, I may never want to go back.

    God has a way of allowing us to be in the right place at the right time.

    I was walking down a dark street late one evening when I heard screams coming from behind a clump of bushes (灌木). Alarmed, I slowed down to listen and soon realized that what I was hearing was the unmistakable sounds of a struggle: mad fighting and tearing of clothes.

    Only yards from where I stood a girl was being attacked. Should I get involved? I was worried about my own safety, and regretted having suddenly decided to take a new route home that night. What if I became another victim? Shouldn't I just run to the nearest phone and call the police?

    The girl's cries were growing weaker. I knew I had to act at once. How could I walk away from this? I finally made up my mind. I could not turn my back on the fate of this unknown girl, even if it meant risking my own life.

    I am not a brave man, nor am I physically strong. I didn't know where I got the courage and strength, but once I had decided to help the girl, I became strangely different. I ran behind the bushes and pulled the attacker off the girl. Struggling, we fell to the ground, where we wrestled for a few minutes until the attacker jumped up and escaped.

    Out of breath, I stood up and approached the girl, who was behind a tree, sobbing. Not wanting to frighten her further, I at first spoke to her from a distance. "It's okay," I said softly. "The man has run away. You're safe now." There was a long pause and then I heard the words, spoken in wonder, in amazement. "Dad, is that you?" And then, from behind the tree, out stepped my youngest daughter, Katherine.

Time is a valuable resource, especially for those who need to deal with academic demands, personal growth, and social activities at the same time. Effective time management . not only leads to increased productivity, but reduces stress. {#blank#}1{#/blank#} . Here are some strategies to help young adults master the art of time management.

Setting clear and achievable short-term and long-term goals is essential for youth.  {#blank#}2{#/blank#}They'll also distribute time accordingly. Whether it's studying for exams or pursuing personal interests, having well-defined goals provides a sense of direction. Meanwhile, importance levels of tasks can vary. By focusing on key tasks and minimizing time spent on unimportant ones, young adults can perfect their time management.

    {#blank#}3{#/blank#} It makes efficient use of their time. Whether using a planner or a calendar app scheduling specific blocks

of time for different activities, including study time, exercise 、socializing, can lead to better time use.

Furthermore, learning to say no is a valuable skill for youth. With numerous opportunities and interests, it's easy to become overwhelmed. By being selective about commitments, young adults can arrange their time and energy

wisely. Saying notonon-essential activities frees up time for important tasks. {#blank#}4{#/blank#}.

In the pursuit of personal success, young adults often find themselves caught up in a series of responsibilities and

commitments. However, it's essential for them to recognize that life shouldn't be like this. Self-care plays a vital role in time management. {#blank#}5{#/blank#} By ensuring they maintain a healthy work-life balance, young adults can recharge their energy levels, improve focus, and increase productivity. That way, they perfect time usage and pave the way for

success.

A、That actually prevents over-commitment.
B、One should constantly review how time is spent.
C、It creates opportunities for personal development as well.
D、Developing a daily schedule helps young adults stay organized.
E、Putting things off constantly is a common time management project.
F、By knowing what they want to accomplish, they can prioritize their tasks.
G、Youth should value adequate rest and activities that promote their well-being.

Is forgiveness against our human nature? To answer our question, we need to ask a further question: What is the essence of our humanity? For the sake of simplicity, people consider two distinctly different views of humanity. The first view involves dominance and power. In an early paper on the psychology of forgiveness, Droll （1984） made the interesting claim that humans' essential nature is more aggressive than forgiving allows. Those who forgive are against their basic nature, much to their harm. In his opinion, forgivers are compromising their well-being as they offer mercy to others, who might then take advantage of them. 

The second view involves the theme of cooperation, mutual respect, and even love as the basis of who we are as humans. Researchers find that to fully grow as human beings, we need both to receive love from and offer love to others. Without love, our connections with a wide range of individuals in our lives can fall apart. Even common sense strongly suggests that the will to power over others does not make for harmonious interactions. For example, how well has slavery （奴隶制） worked as a mode of social harmony?

From this second viewpoint of who we are as humans, forgiveness plays a key role in the biological and psychological integrity of both individuals and communities because one of the outcomes of forgiveness, shown through scientific studies, is the decreasing of hatred and the restoration of harmony. Forgiveness can break the cycle of anger. At least to the extent the people from whom you are estranged （不和的） 'accept your love and forgiveness and are prepared to make the required adjustments. Forgiveness can heal relationships and reconnect people. 

As an important note, when we take a Classical philosophical perspective, that of Aristotle, we see the distinction between potentiality and actuality. We are not necessarily born with the capacity to forgive, but instead with the potential to learn about it and to grow in our ability to forgive. The actuality of forgiving, its actual appropriation in conflict situations, develops with practice.
