1    (dress) in orthopedic(矫正的) shoes, a penguin from the San Diego Zoo, who could not walk due to illness, got another chance to run like other penguins.

Lucas, the African penguin,     2    (have) trouble walking for more than three years because of the problem in his spine(脊柱), which causes its muscle weakness and pain in the legs.

The penguin looked lonely and different     3     other ones for its limited mobility. Wildlife     4    (researcher) decided to do something.

“I’ve known Lucas for a long time, so being able to provide him with a     5    (possible) to live a normal life brings a smile to my face,” said Dr. Beth, a senior vet at the zoo.

The boots     6    (fit) in place, so they will help Lucas to fully participate in the colony and show behaviors that are more typical for    7     penguin-such as climbing the rocks, swimming, nesting and finding a suitable mate.

With his new boots, Lucas’s walking has improved, which makes his exploration in his rocky habitat     8    (easy) and his posture(姿势) became more natural,     9    (allow) him to gain better balance while standing.

“We were pleasantly surprised at the change the boots bring,” said one animal keeper. “Seeing him move about now gives us hope     10     he may be able to live a full life.”

Scientists exploring the ocean floor in Antarctica have found a larger group of fish nests than ever before. The discovery came     1     a surprise, and it will help scientists develop a more complete idea of the ocean food web in the area.

In the south Weddell Sea, not far from Antarctica’s Filchner Ice Shelf, scientists were    2     (amaze) to discover a group of about 60 million icefish nests on the ocean floor. Before this, the     3     (large) group of icefish nests that had ever been found includes less than 60 nests. Lilian Boehringer, a research student, was the first     4     (discover) the nests. “They were everywhere,” she told The New York Times.

The researchers used a special device called OFOBS to make two more four-hour “dives” ,    5     (try) to discover the limits of the nesting area. The nests scientists found were in the shape of     6     circle. Each nest held about 1,700 eggs. Usually, Weddell seals (海豹)    7     (spot) in the waters above the nesting site. Trackers     8     (fix) on some Weddell seals show that they dive all the way to the sea floor.

The team placed a camera on the sea floor before leaving,     9     will take a picture of the nests in the area     10     (two) a day for the next two years. They hope the pictures from this camera will help them learn more about the lives of the icefish.

The city of Canberra     1     (date) back to 1913 when it was purposefully built to be the capital of the nation of Australia. It has grown over time to not only be the seat of the government of the nation, but also a city with     2     (it) own culture.

It sits on the shores of Lake Burley Griffin and is one of the     3     (good) places to travel to in all of Australia for anyone looking forward to     4     (find) out more about the history of the country and the people. Some of the more interesting things to see in Canberra include Australian National Botanic Gardens and kangaroos in     5     wild, which are exactly fit     6     those nature-lovers.

Visitors can enjoy themselves in Canberra, but they should try to make travel     7     (arrangement), so that they can attend any of the festival activities     8     are interesting and exciting. There are many     9     (office) and folk festivals in Canberra. Canberra Day is     10     (actual) a public holiday to celebrate the naming of Canberra. Canberra also offers the chance to learn a little bit about how Australia was formed, and how it developed.

In the heart of modern Beijing is the Forbidden City. It served as the political center of ancient China between 1420 and 1912 and now it is     1     world famous museum.

The Forbidden City     2     (build) by Emperor Yongle, the third Ming ruler,     3     moved the capital from Nanjing to Beijng in 1403. Sources say it took a million     4     (worker) to build it between 1406 and 1420. Legend has it that the Forbidden City was redesigned to have 9, 9991/2 rooms. Half a room is missing to avoid     5     (upset) the God of Heaven. The maincolors of the Forbidden City are yellow and red. The walls, doors, and windows were     6     (most) painted in red, a symbol of     7     (happy) in Chinese culture.

The English name “Forbidden City” is a translation of the Chinese name Zijincheng. In the past, it was forbidden to ordinary people and that is     8     the Forbidden City is so named. After the Qing Dynasty, it was made a     9     (nation) museum-the Palace Museum and was open to the public. As one of the world’s largest cultural museums, the Palace Museum holds more than a million rare and valuable works of art. So do find a chance     10     (visit) it some day!

The Jiaohe Ancient City Ruins,     1     (locate)10 kilometers west of Turpan, Xinjiang Uygur autonomous region is the largest, oldest and best-preserved earthen architectural site in the world,     2     holds great political, cultural, historical and artistic value.

Guri Bakri, a 39-year-old conservator of the Jiaohe Ruins, starts her daily inspection at the site as usual, ensuring the safety of tourists and     3     (make) photographic records along the way. She is the third generation of Guri’s family who have been working as local cultural conservators,     4     (constant) guarding this historic site since her grandfather     5     (become) the only conservator in Jiaohe in 1961.

After graduating in 2013, Guri returned to her hometown and became one of her father’s     6     (colleague). Talking about Jiaohe, Guri said that she would always remember June 22, 2014, when the Jiaohe Ancient City Ruins     7     (name) the World Heritage Site. She was proud of her participation in the application     8     the title.

In recent years, the state cultural protection department has invested more than 100 million yuan ($ 14.8m) in the     9     (protect) of Jiaohe Ancient City Ruins. This year, Jiaohe Ancient City Ruins will take the fifth round of structural reinforcement (加固).     10     team of conservators has also expanded to 12. This old city of more than 2,000 years is gaining new energy.

A new study shows that     1     two countries with the world’s     2     (large) populations are leading the increase in greening on land. The effect comes     3     (main) from ambitious tree     4     (plant) programs in China and agriculture in both countries.

China alone accounts     5     25% of the global increase in leaf area with only 6.6% of global vegetated (有植物的) area. The greening in China is from forests (42%) and croplands (32%).

China’s outsized     6     (contribute) comes in large part from programs intended           7     (protect) and expand forests, in an effort to reduce the effects of soil erosion (侵蚀), air pollution and climate change.

Taken all together, the greening of the planet represents an increase in leaf area of plants and trees equal to the area     8     is covered by all the Amazon rainforests.

Land area     9     (use) to grow crops is comparable in China and India and     10     (change) very little since the early 2000s. Yet the countries have greatly increased both their annual total green leaf area and their food production.

China has detailed measures to boost its climate change monitoring and risk prevention capabilities, marking a significant step forward in the country’s efforts     1     (enhance) its climate resilience(气候适应性) .

The country will seek to build a climate-resilient society     2     climate change monitoring and early warning capability will reach an advanced level globally and the climate risk management and prevention system will     3     basic mature, according to the national climate change adaptation strategy 2035, jointly     4     (publish) by 17 departments including the Ministry of Ecology and Environment.

The first time China     5     (issue) a national climate change adaptation strategy, China took measures to prevent and control major climate-related disaster risks     6     an effective manner, and greatly improved the technical and standard system for adapting to climate change. Since then, positive results     7     (achieve) in improving adaptation to climate change in key regions and industries.

As the global climate     8     (far) warms, the long-term unfavorable effects and extreme weather events brought about by climate change will pose     9     increasingly serious threat to China’s economic development. The document underlined measures to improve climate change monitoring and forecasting services, enhance assessment of climate change impacts and risks, and     10     (strength) disaster prevention.
