Last weekend, I took part in a forest clean-up activity. It was organized by GreenHope,     1     an organization devoted to protecting forests. At first I didn’t want to take part in the forest clean-up activity, but then I thought. What if nobody goes?” our team leader, Joe, took us to a forest outside the city.     2     I was sad to see litter everywhere. There was a “No littering is allowed here” sign at the entrance to the forest,     3     but that didn’t stop people from throwing their rubbish on the ground. Joe divided us into two groups: one group cleaned up the north side of the forest, and the other group cleaned up the south. We worked for several hours and we were happy to see that the forest looked cleaner than it had looked before.     4     这绝对值得我们的努力. There’ll be another clean-up activity in the green belt next Saturday. You can find Joe and sign up if you’re willing to help.     5    每个参加该活动的人都将获得一枚奖章. I’ll join you too if I have time.

After learning the basics of tai chi in those first few classes, I found myself bored and aching from doing the same moves over and over again. Luckily, my coach taught me how to relax my muscles and focus on peace of mind while performing the routine. With these requirements of tai chi in mind, I found to my satisfaction that     1     我的平衡性和柔韧性慢慢有所改善, that I was able to do more difficult moves, and that my love for tai chi returned stronger than ever.

In time, I began to look into the ancient Chinese culture behind tai chi. I discovered that     2     tai chi is deeply rooted in the Chinese philosophy of yin and yang, which are believed to form the unity of opposites. Neither can exist independent of the other; for example, there is no shadow without light. The practice of tai chi aims to maintain the balance of yin and yang in the body through opposite movements. Eventually,     3     tai chi brings about a state of physical balance and mental peace.

A year of practising     4     tai chi has had a positive effect on my everyday life. I sleep better at night, and I am more energetic during the day.     5     我感到更快乐和更自信了. Tai chi has taught me to relax my mind, enabling me to stay cool in stressful situations. I am sure I will continue to practise tai chi and enjoy the benefits it has brought me.

Traditional festivals are a significant part of Chinese culture, which we must protect and maintain.     1     这样做有三个理由.

First of all, traditional festivals teach us a lot about our nation’s history. For example,     2     the Dragon Boat Festival is celebrated in honour of Qu Yuan, a great poet.

    3     Traditional festivals also enable us to learn more about fine Chinese values. Many festivals, such as the Mid-Autumn Festival, have a caring, family-centred message at their heart. The full moon on the festival stands for family togetherness and     4     family members will come back home even if they live very far away.

Last but not least, traditional festivals are a source of national pride and help shape our national identity. That’s why we celebrate the Hanshi Festival and the Laba Festival with unique customs, and these shared experiences bring us together as a people.     5     传统节日告诉我们我们是谁and fill us with pride of being Chinese.

Exercise has a range of health benefits. However, some people believe that     1     if some exercise is good, more is always better, so they tend to exercise for a long time without stopping. For example, some people go jogging for several hours at a time because of the step-counting smartphone apps.     2     还有些人周末连续锻炼数个小时 to make up for their lack of exercise during the weekdays. Habits like these put stress on the body, and if maintained over the long term,     3     they can be a serious health risk.

Generally speaking, aerobic routines that last over 100 minutes have a certain health risk. On the other hand,     4     they should not be shorter than 10 minutes. If you do exercise for only a few minutes, you may not be working out long enough to see any benefits from it. When you exercise, aim for the daily average of 30 to 60 minutes.     5     这将会防止你受伤. Moreover, it will ensure that the exercise you do has a positive effect on your physical health.
