4 . Being healthy is important. Often, we’re crazy about articles in health magazines talking about the latest popular diets, or advertisements that offer cures (疗法) for fatness that are often too good to be true. One of the latest crazy phenomena (现象) is intermittent fasting (间歇性禁食).     1    

There are different ways of intermittent fasting.     2     Another common way is choosing a diet that sees people only eating during a limited part of the day, for example, over eight hours.

    3     A study suggests intermittent fasting may help control blood sugar and reduce the possibility of suffering related disease. Other studies have shown intermittent fasting may help slow the ageing process, support brain function, lose weight, etc.

Some people try intermittent fasting for weight management, and others use the method to deal with some conditions such as high cholesterol or arthritis.     4     Fasting might not suit those who are underweight or with a long-term medical condition. Fasting may cause some people to experience symptoms (症状) such as headaches or make them easily suffer from overeating after a reduced calorie intake (热量摄入) day.

As with many diets, it’s always wise to speak to your doctor or weight-loss professional before changing your eating habits. And, at the end of the day, it could just come down to what lifestyle choice suits you.     5     If not, your health may suffer.

5 . Taking exercise in a crowded, noisy gym will improve your muscle but may not make much difference in your stress level. By contrast, hiking improves not only your physical fitness level, but your mental health as well. “I hike with friends every week. Whether I am wandering down a flat path along a river or climbing a rock y mountain in the wilderness, hiking can be beneficial to me because it exposes (使接触) me to outdoor scenes such as mountain s and rivers, which can always offer me good ideas about paintings and music,” Marry Copper, a hiker said.

Experts agree that hiking reduces stress. According to the Anxiety Disorders Association of America (ADAA), hiking increases the body’s production of endorphins, a type of chemical that improves mood (情绪). Endorphins also help you sleep more soundly, which will lower your stress level. However, not all scientists agree that hiking raises your endorphin level. Instead, some researchers believe that hiking causes the release of the chemical norepinephrine, which helps make you less excited or upset.

The controversy (争议) is ongoing, but it is clear that however it happens, hiking is useful when you are feeling anxious. Hiking can also help improve your confidence. Walking down a path is a repetitive motion, which can lead your brain into relaxing; you may “zone out” to the point where you won’t be thinking about anything in particular. Being outside in the open air may also help you exercise better because most people do indoors; getting out from under a roof can lift your spirits.

Hiking may improve your mood more than a gym workout will, but your risks are also greater. People sometimes try to make their own way rather than stick to established paths. They are proud to say they like to have an adventure. However, people who try to do something new could be attacked by wildlife and get hurt and lost. So stick to the known roads and bring a cellphone with you, and always tell someone where and when you are going hiking, even if you have a partner going with you.

7 . This is the last Christmas that Faye and Matthew have spent in their house, which has already been sold. Faye and Matthew Gooding and their five young sons appear to have perfect lives. For the couple themselves, however, this “materially perfect world” was lacking in something—so now they are giving up all their possessions to travel around the world with their children. Most of their belongings have been given to their neighbors. Faye said, “It is a relief to get rid of so many possessions. Thankfully, our parents understand and support us.”

“I hesitated for a while because some friends think Faye and I are mad to give up so much. When we told the older boys, they were so excited that they were going to have so much time as a family. It made me realize the amount of toys or material possessions can’t replace time spent with our children. They’ve had to give away so many toys, bikes and books. My wife Faye was so determined to keep to our plan,” said Matthew.

They will leave this month and plan to start their travels in Sweden where they have friends. Faye said, “My older boys plot where we go next but we hope to see Europe and over two years travel as far as Japan, America, Bali and Thailand. We don’t plan to hire any tour guides. We just depend on a compass and local people to move in the right direction.”

Faye, who posts on Instagram as a mother of five boys, added, “It is a risk because we are giving up so much. I, however, even plan to quit my job after the travel. We can’t wait to spend more time with our sons without the stresses of everyday routines. We don’t know what will happen, but we do know if we didn’t do this we would always regret it.”

10 . Here in eastern Spain, human towers are very popular. The tower sometimes falls because it’s so high. I used to ________ to be up there, but for the past year, I’ve been practicing ________. So today, I finally became a casteller — a castle constructor.

My friend Tomeu was also part of our team. Tomeu had been a casteller before. “What if I’m not ________ for this?” I asked him. Tomeu smiled, “We’re never ready, Jordi. Just trust those below who ________ you up and yourself. Have faith!”

It was our turn. We first made the ________ for our tower. My father and three of the strongest men formed a ________ facing each other as they held each other’s arms tightly. Four more strong men stepped behind, each wrapping his arms around the ________ of a man and giving him a bear hug. Four smaller men climbed onto the backs of the ________ group and stood on their shoulders.

Our base was solid, so my father ________ and we continued building. After the sixth tier (层) was set up, it was my turn.

“Have ________!” Tomeu said to me again. I passed the first two tiers ________ because the people were leaning forward. But the higher I went, the more unstable the tower became. By the time I reached the sixth tier, the tower below me ________ a bit. My heart began a crazy dance in my chest. I took a deep breath to ________ myself. Reaching deep inside to feel my ________, I rose slowly out of my crouch (蹲伏) and straightened my knees. I waved my hand to the judges, meaning our tower was ________.

Far below, I could hear the crowd’s cheering.
