Until last year, I was trying to look like the slim girls on TV even though I knew that it was     1     (possible). To lose weight, I tried every new diet I read about online. I tried no-fat, low-fat, 5:2, only bananas, no bananas-I almost     2     (go) mad.

Then an article changed me. It said instead of asking “Am I fat?” I should be asking “Am I fit?” I didn’t know a letter could make such a     3     (different)! Then I started thinking about fitness rather than weight. I didn’t say that I wanted to lose three kilos. Instead, I would say I wanted to run two kilometres in eight     4     (minute) or I wanted to be able to do 30 push-ups. I preferred     5     (add) healthy foods to my meals rather than cut     6    the foods I enjoyed. I still had a burger now     7     then, but I would add a salad or an apple.

Finally, I stopped     8     (compare) myself with actresses and models and looking for things that were wrong with my face or body. Instead, I made a list of the things I liked about     9     (I). I became more positive about myself and my body. As     10     result, I became both happier and healthier.

Economic development is necessary if we want to     1     society. There comes a time     2     the old must give way to the new, and it is not possible to     3     everything from our past as we move towards the future. Finding and keeping the right     4     between progress and the protection of cultural sites     5     be a big challenge.

Big challenges, however, can sometimes lead to great     6    . In the 1950s, the Egyptian government wanted to build a new dam across the Nile in order to control floods, produce electricity, and     7     water to more farmers in the area. But the     8     led to protests. Water from the dam would likely damage a number of temples and destroy cultural relics that were an important part of Egypt’s cultural     9    . After listening to the scientists who had studied the problem, and citizens who lived near the dam, the government     10     to the United Nations for help in 1959.

Tibetan antelopes live on the plains of Tibet, Xinjiang, and Qinghai.    1    them move slowly across the green grass, I’m struck by their    2    . At the same time, I’m also reminded    3    the danger they are in. They are being hunted,    4    , for their valuable fur.

Zhaxi, a villager from Changtang, works at the Changtang National Nature Reserve. “We’re not trying to save the animals,” he says. “    5    , we’re trying to save ourselves.” The 1980s and 1990s were bad times for the Tibetan antelope.    6    population dropped by more than 50 percent. Hunters were shooting Antelopes to make    7    . Their    8    were becoming smaller as new roads and railways were built.

In order to save them, the Chinese government placed them under national protection. The measures were    9    . The antelope population    10    and in June, 2015, the Tibetan antelope was removed from the endangered species list.

Everywhere    1     looked, there was nothing but ruins. Nearly everything in the city was    2    . About 75 percent of the city’s factories and buildings, 90 percent of its homes, and all of its hospitals were gone.     3     covered the ground like red autumn leaves, but no wind could blow them away. Most bridges had fallen or were not safe to cross. The railway tracks were now useless pieces of metal. Tens of thousands of cows, hundreds of thousands of pigs, and millions of chickens were dead. Sand now    4     the wells instead of water. People were in    5    .
