There comes a time when the old must give way to the new, and it is not possible to preserve(preserve) everything from our past as we m

2、ove towards the future. Finding and keeping (keep) the right balance between progress and the protection (protect) of cultural sites can be a big challenge Big challenges, however, can sometimes lead to great solutions (solution). In the 1950s, the Egyptian government wanted to build a new dam acros

3、s the Nile in order to control (control) floods, produce electricity, and supply water to more farmers in the area. But the proposal led to protests (protest). Water from the dam would likely damage a number of temples and destroy cultural relics that were an important part of Egypts cultural herita

4、ge. After listening (listen) to the scientists who had studied (study) the problem, and citizens who lived near the dam, the government turned to the United Nations for help in 1959. A committee was established(establish) to limit damage to the Egyptian buildings and prevent the loss of cultural rel

5、ics. The group asked for contributions (contribute) from different departments and raised funds within the international (internation) community. Experts investigated the issue, conducted several tests, and then made(make) a proposal for how the buildings could be saved (save). Finally, a document w

6、as signed (sign), and the work began in 1960. The project brought (bring) together governments and environmentalists from around the world.

7、961, German engineers moved the first (one) temple. Over the next 20 years, thousands of engineers and workers rescued 22 temples and countless cultural relics. Fifty countries donated nearly $80 million to the project.When the project ended in 1980, it was considered a great success. Not only had t

8、he countries found a path to the future that did not run over the relics of the past, but they had also learnt that it was possible for countries to work together to build a better tomorrow.The spirit of the Aswan Dam project is still alive today. Perhaps the best example is shown (show) by UNESCO,

9、which runs a programme that prevents world cultural heritage sites around the world from disappearing (disappear). If a problem seems too difficult for a single nation, the global (globe) community can sometimes provide a solution. PROMOTING CULTURE THROUGH DIGITAL IMAGES Lanzhou, 9 August 2017. A g

10、roup of researchers and scientists (scientist) from China and other countries are working together to help increase knowledge and appreciation (appreciate) of Chinas ancient cultural heritage.

11、re a key stop along the Silk Road throughout Chinas ancient history. Nearly 500,000 high-quality digital photographs have been produced (produce) since the international project started (start)in 1994.The Mogao Caves have long been a meeting (meet) point for different cultures and are part of the hi

15、. Appreciating the cultural heritage of other countries is very important for international communication and understanding.” Unit2 Wildlife Protection A DAY IN THE CLOUDS The air is thin and we have to rest several times (time)on the short hike from camp. To our left, snow-covered (cover) mountains

16、 disappear into clouds that seem almost close enough to touch (touch). On the plain in front of us, we can just make out a herd of graceful (grace) animals. This is why were hereto observe (observe) Tibetan antelopes. Tibetan antelopes live on the plains (plain) of Tibet, Xinjiang, and Qinghai. Watc

17、hing (watch) them move slowly across the green grass, Im struck (strike) by their beauty (beautiful). Im also reminded of the danger they are in.

18、nation)Nature Reserve. The reserve is a shelter for the animals and plants of northwestern Tibet. To Zhaxi, the land is sacred and protecting (protect)the wildlife is a way of life. “Were not trying to save the animals,” he says. “Actually (actural), were trying to save ourselves (we) The 1980s and

19、1990s were (be)bad times for the Tibetan antelope. The population dropped by more than 50 percent. Hunters were shooting antelopes to make profits (profit).

22、 disappeared. In the evening, I drink a cup of tea and watch the stars. I think about the antelopes and what Zhaxi told me. Much is being done (do)to protect wildlife, but if we really (real) want to save the planet, we must change our way of life. Only when we learn to exist in harmony with nature

23、can we stop being a threat to wildlife and to our planet.
