The air is thin and we have to rest several     1    (time) on the short hike from camp.    2    our left，snow-covered mountains disappear into clouds that seem almost close enough    3    (touch).On the plain in front of us, we can just make     4    a herd of graceful animals. This is     5    we’re here - to observe Tibetan antelopes.

Tibetan antelopes live on the plains of Tibet, Xinjiang, and Qinghai.     6    (watch) them move slowly across the green grass, I     7    (strike) by their beauty. I’m also reminded     8     the danger they are in. They are being hunted     9    (illegal), for their valuable fur.

My guide is Zhaxi,     10    villager from Changtang. He works at the Changtang National Nature Reserve. To Zhaxi the land is sacred and     11    (protect) the wildlife is a way of life.He says. “Actually,we’re trying to save     12    (we).”

The1980s and 1990s were bad times for the Tibetan antelope. The population dropped     13     more than 50 percent. Their habitats were becoming     14    (small) as new roads and railways were built

In order to save this species from     15    (extinct),the Chinese government placed     16    under national protection Zhaxi and other volunteers watched     17    the antelopes day and night to keep them safe     18    attacks. Bridges and gates were added     19     (let) the antelopes move easily and keep them safe from cars and trains.

The measures were     20    (effect). The antelope population has recovered and in June 2015, the Tibetan antelope     21    (remove) from the endangered species list. The government,however, does not intend to stop the protection programmes,     22     the threats to the Tibetan antelope have not yet disappeared.

I think about the antelopes and     23     Zhaxi told me. Much is being done to protect wildlife, but     24    we really want to save the planet, we must change our way of life. Only when we learn to exist in harmony with nature can we stop being     25     threat to wildlife and to our planet.

7 . In the digital age, we rely on technology such as social media to try to build interesting and varied lives. Social networking sites are designed and promoted to make us believe enthusiastically that they are able to open up new experiences for us. There are constant notifications (通知) and updates, urging us to log in to find out what is new.

But if we do not use the technology wisely, we can end up becoming trapped in a cycle of social media FOMO, a sign of deeper unhappiness. FOMO, or fear of missing out, is the fear that exciting or interesting events are happening somewhere else and that we are not able to take part.

People who experience high levels of FOMO have been found to be more likely to give in to urges to compose and check text messages while driving, as well as to use Weibo, TikTok, etc more often directly after waking, while going to sleep and during meals.

When it comes to lasting happiness, it is best not to give in to FOMO, but rather to deal with the cycle of desires that fuel it. Hard as it is, it is better to work toward facing the fearful reality that we cannot experience everything we might like than to get caught in a cycle of checking behaviors that only cause anxiety.

If we have become used to using social media as part of our attempts at living interesting lives, we must admit that it is not easy to change our approach. But change is almost always worthwhile in the long run.

The fact that FOMO is so common in our digital age is a sign that there is something wrong with the way we are pursuing happiness and that we are not as happy as we might think we are. It should warn us that, in our eagerness to use digital technology to try to make ourselves happier, we may unintentionally bring on exactly the opposite result.

It was a rough week. The price of oil skyrocketed as the temperature dropped sharply in Maine. We were looking at a high of eight degrees that week, and I had missed three days of work so my paycheck was going to be lower than normal. I was stressed, to say the least. I shopped strategically looking for every possible way to cut pennies so I could buy groceries and keep the house warm.

My eight-year-old son didn’t understand when I told him we were struggling that week. He wanted a special kind of yoghurt, but I didn’t have the extra three dollars to buy it for him. It was the kind of yoghurt with a cartoon kid riding a skateboard on the front of the box, and a mere two spoonfuls in each cup. It was the kind of product that wastes a parent’s money and makes me hate advertising.

I felt guilty as a parent when those big eyes looked at me with confusion, as if to say, “It’s just yoghurt. What’s the big deal?” So I found a way. I put something back as single mothers often do. He got his yoghurt.

On the way driving back from the grocery store, I noticed a homeless man holding a sign by the side of the road. My heart hurt, and I tried not to look at him. I watched people stay away from him on the street and walk by without even meeting his eyes. My son didn’t seem to care much, either. I looked at the man closely then - bare hands grasping a piece of cardboard, snot (鼻涕) frozen to his face, a wornout jacket. And there I was struggling because I had to buy oil and groceries. But I decided to help. I pulled over to the man and handed him a five-dollar bill.

Seeing this, my son became confused and surprised. _______________________________________________________________________________ I explained that if we were blind to the poor man’s situation he would be freezing. He didn’t have a home or food to eat after all. We could spare five dollars even if we were financially stressed. ______________________________________________________________________________

On that day, my son performed an act that most adults wouldn’t have done._____________________________________________________________________________ Even if it was just a matter of a few spoonfuls of yoghurt it was all he had, and he gave it to someone who needed it more than he wanted it. He showed me that I am doing well as a mother! _______________________________________________________________________________
