As we know, sports activity can make people more energetic and     1     (healthy) physically and mentally. However, everything has two sides. Sports are no exception. If you are not careful or do excessive (过度的) training, you     2     (hurt) yourselves. Thus, make sure that you do sports     3     (regular) and do not overdo it.

Chinese martial arts are famous all around the world. Each year, tens of thousands of people from other     1     (country) come to China to learn Chinese martial arts. Tai Chi,     2     is a martial art with a long history, is usually a popular choice. It involves doing very slow physical exercises     3     (relax) your mind and calm your body.

I agree with Mr. Zhang’s idea     1     sport can help improve health and mood     2     people of all ages. I had a similar experience last year. I quit the basketball team     3     I thought I didn’t have enough time for it. After     4     (quit) I felt sad and had no energy. I quickly lost my     5     (fit) too. I spoke to my parents who agreed I should rejoin the team. Now I play every week and I’m happy and healthy.

Winter is here! Are you also wondering how that happened so quickly? If you are now experiencing the     1     (pleasant) effects of little sunlight, you are not alone.

Many people’s mood goes slightly down as the days are getting shorter. Even if you don’t suffer from SAD (Seasonal Affective Disorder),     2     is also called winter depression, you might feel different than just a few weeks ago.

Does that sound familiar? If so, I hear you and a possible solution can     3     (recommend) to you! That is—laughter!

As Mirthy’s Laughter Yoga Leader, I     4     (strong) believe in the health benefits of laughter, which are indeed impressive. The most obvious gain is that     5     puts people in a good mood. After     6     (assess) mood levels before and after the Laughter Yoga session, we find many participants’ mood goes up by at least two points—and that’s without drugs or pills, just by “a little bit” of laughter.

Dr Madan Katana, who is a medical doctor and created Laughter Yoga,     7     (do) quite a bit of research and found that laughter is a mild antidepressant (抗抑郁药) as it releases endorphins and serotonin. What’s more, laughter can be     8     natural pain killer—and without side effects.

Laughter is also a great stress relief and reduces the levels of stress hormones in our bodies. If you keep in mind that almost 90% of all illnesses are associated with stress and tension     9     (hold) in our body, laughter is an easy remedy, isn’t it? So there is some     10     (true) in the old saying: “Laughter is the best medicine.”—well, at least it’s a start!
