More than 11,000 scientists from 153 countries have sounded the alarm on climate change. In a paper     1     (publish) last week in the journal BioScience, they signed a declaration (声明) stating clearly that planet Earth is facing a climate emergency, saying that if no changes     2     (make), the world will face untold suffering. The evidence that the scientists collected reveals an undeniable truth    3     human activities have been causing global warming from the fast rise of fossil fuel consumption    4     the increase in greenhouse gas emissions (排放) over the past 40 years.

The scientists also gave some instructions to fight against global warming,     5     (propose) six actions to prevent further disasters: stabilizing population     6    (grow) by investing into family-planning services and girls’ education, replacing fossil fuels, cutting the emissions of climate pollutants, eating less meat, restoring and protecting ecosystems, and building     7    carbon-free economy.

The scientists say the climate crisis is     8     (close) related to human activities, so they call on people     9     (change) their life styles. But these measures are comparatively abstract.    10    , it is high time for policymakers to figure out more practical measures that can bring down carbon emissions.

I was recently fortunate enough to have the opportunity to travel to Suzhou in Jiangsu Province. As    1    amateur student of history, I have always been fascinated with this incredible city and had    2    (particular) high expectations.

Upon landing and heading to my hotel, I began to wonder what the scenery around my hotel would be like. The following few days    3    (find) me floating down the ancient canals in the “Old Town” district of Suzhou, visiting its gorgeous and historic gardens,    4    (explore) the many markets of the city and taking advantage of every opportunity I could to eat favorable Suzhou cuisine. I found myself    5    (overwhelm) by the infectious energy that surges (涌动) through the city.

This “energy of Suzhou” is represented best by its people. Suzhou people have enormous respect for    6    (they) city’s history, while also having an innovative eye on the future. Suzhou served    7    a key trading hub for much of China’s history, drawing in scholars, engineers    8    merchants from all over the country for thousands of years.

The entirety of Suzhou    9    (be) a true treasure of China that manages the difficult balance of innovation and preservation. I eagerly await what extraordinary    10    (accomplish) it will surely achieve next.

Each city has its own unique cultural symbol,    1    (break) the similarity of cities. The    2    (significance) cultural symbols such as Beijing’s Forbidden City, Hangzhou’s West Lake and suzhou’s gardens have helped form strong cultural confidence.

Qinhuangdao is focusing on fashion tourism. A first-class international tourist city needs wold tourist attractions, and Qinhuangdao seems    3     ( have ) some ,The Great Wall is world-class, and so    4     (be) the Beidaihe wetlands.

Qinhuangdao has successfully transferred the world’s unique cultural symbol，The Classic ofMountains and Seas，into the city’s cultural    5    ( develop). Qinhuangdao is the only city in China    6    (name) after an emperor’s imperial name.The West Port of Qinhuangdao is near the legendary place where Qin Shi Huang    7    ( seek ) immortality(永生) into the sea. At the West Port cruise terminal, the 350-meter-long giant murall The Illustrations of Mountains and Seas reaches far away by the waves of the Bohai Sea. It is presenting the ancient wonder of the book which is rich    8    myths and legends to foreign visitors and sending Eastern culture and philosophical thoughts to a wider stage.

A distinctive and unique city cultural symbol can improve recognition and identity,    9     will help to enhance the city’s attractiveness. With a cultural symbol, there is cultural confidence,and it is    10    deepest power a city has.

The World Health Organization (WHO) has announced a shocking finding about the air we breathe. It has found that almost everyone on Earth breathes unhealthy air. The WHO made     1    (it) air quality update ahead of World Health Day on April 7. The update reported that 99 per cent of the world’s population breathes air     2     goes beyond WHO air quality limits. It looked at data from over 6,000 cities in 117 countries. People     3    (live) in lower- and middle-income countries breathe the poorest-quality air. Millions of people die in these countries because of pollution-related diseases. The WHO said: “After surviving a pandemic, it is unacceptable to still have 7 million preventable deaths due     4     air pollution.”

The WHO said its report highlighted the need to move away from fossil fuels. It asked governments to do more     5     (reduce) levels of air pollution. It said: “Current energy concerns highlight the importance of speeding up the transition to cleaner and     6    (healthy) energy systems.” It added that high gas prices, energy     7    (secure), the dangers of air pollution, and climate change mean the world must be less dependent on fossil fuels. The WHO report     8    (include) many recommendations for change. One of these is     9     use of clean energy for cooking, heating and lighting. Another is to “build safe and affordable public transport systems and pedestrian- and cycle-friendly     10    (network)”.

The Ming City Wall Ruins Park, one of the best parks in Beijing,     1     (locate) in the central area of Beijing from Chongwenmen East Street to Dongbianmen.     2     (cover) a total area of about 15.5 hectares, the park     3     (consist) of 3.3 hectares of city wall ruins and the southeast corner tower, and 12.2 hectares of green space.

The Ming Dynasty City Wall from Dongbianmen to Chongwenmen is one of the only two remaining Ming Dynasty City Walls in Beijing.     4     (historic), the Ming Dynasty City Wall is 25 kilometers long and was first built in the 17th year of the Yongle Period of the Ming Dynasty (1419 AD), and has     5     history of over 580 years. The remaining relic,     6     is about 1.5 kilometers long, used to be part of the inner city wall of Beijing. It is the     7     (long) section of the city wall remains in the city, and an important symbol of Beijing.

Using a simple design, the park highlights the beauty of the     8     (ruin) city walls. The “Old Trees and Ming Walls”, “New Charm of Ancient Buildings” and other sceneries in the park have a long history and rich connotation (含义), showing the profound     9     (culture) accumulation of Chongwenmen, which adds endless imagination     10     people’s mind.
