The African penguin is expected to go extinct in the wild in just over a decade, given its current population decline. The main reason is a lack of food caused by disturbance to ocean conditions from global heating and     1     (compete) from the commercial fishing industry. According to a study, recently scientists     2     (identify) a possible additional cause, one that is an entirely new threat and that further     3     (prevent) the penguins from finding food: noise pollution from marine ships in a bay.

Flash floods hit Longcaogou of Pengzhou, Southwest China’s Sichuan Province on Saturday. Seven people     1     (kill) and eight others slightly injured. Local authorities announced on Sunday, noting that some tourists     2     were camping in the dried-up river were trapped in the flood after failing     3     (escape) in time.

More than 500     4     (rescuer) are conducting a search of valleys and rivers to find lost tourists over the weekend, said local authorities, adding that at least 15 professional rescue teams,     5     (include) mountain rescue and diving rescue teams, are taking part in the rescue work. The rescue work at the scene     6     (draw)to a close.     7     Longcaogou was hit by floods in 2015 and 2017, it has not stopped tourists from visiting the area.

Meanwhile, Longcaogou has been     8     (wide) recommended on social media platforms     9     a “new Instagram-worthy location” and a “nice holiday resort.” Many bloggers posted pictures of the valley’s beautiful scenery and their trips on     10     lifestyle-sharing platforms with captions recommending that people go there.

Over and over at the UN climate summit in Glasgow, world leaders have stressed the need     1     (limit) global warming to 1. 5 degrees Celsius. Experts have said crossing the 1. 5 ℃threshold(界限）risks     2     （release) far more severe climate change effects on people, wildlife and ecosystems. Preventing it     3     (require) almost halving global CO₂ emissions(排放) by 2030 from 2010 levels and cutting them to net-zero by 2050.

Already, the world has heated to around 1. 1℃ above pre-industrial levels. Each of the last four decades was     4     (hot) than any decade since 1850. “We never had such a global warming in only a few decades,” said climate     5     (science) Daniela Jacob at the Climate Service Center Germany.

More warming to 1. 5 ℃ and beyond will     6     (worse) such impacts. For example, heatwaves would become both more frequent and more severe. A warmer atmosphere can also hold more moisture(水分), resulting in more extreme rainfall     7     raises flood risks. It also increases evaporation, leading to more intense droughts.

“At 1. 5 ℃, there’s     8     good chance that we can keep most of the Greenland and west Antarctic ice sheet     9     collapsing,” said climate expert Michael Mann at Pennsylvania State University. That would help limit sea level rise to a few     10     (foot) by the end of the century.

March 12th is China's annually National Tree-planting Day. On this day, millions of Chinese, from all walks of life, will put their works at hands aside for     1     moment, take shovels and buckets as well as saplings, and trek out to green up their hometowns.

First     2    (create) by the US agriculturist Sterling Morton in 1872, Tree-planting Day was set in order to inspire people's passions for planting and protecting trees, and     3    (protect) and improve the     4    (nature) environment on which people depend on for their living.

China's Tree-planting Day could date back     5     a proposal made by Sun Yat-sen (1866-1925), a great China revolution leader, to Beiyang Government (1915-1927) in 1915 and then regulation was     6    (formal) publicized that Tomb-sweeping Festival (April 5th)     7    (adopt) as Tree-planting Day. However, April 5th was a late time for tree-planting in Southern China and so it was changed to March 12th by the Nanjing National Government (1927-1949) in order to memorize Sun Yat-sen,     8     passed away on March 12th.

In February 1979, the 5th National People's Congress of People Republic of China made a     9    (resolve) that March 12th would be taken as Chinese Tree-Planting Day, requiring the whole country to carry out tree-planting     10    (activity) on this day and support the construction of forestry.
