Zhangye National Geopark, which    1     (lie) in Northwest China’s Gansu Province, is blessed with a splendid Danxia landform area    2     (cover) about 1,289 square kilometers. The Danxia landforms are    3     masterpiece of nature. The colorful mountain ridges are just like an overturned palette from heaven. Bands of fiery red, creamy orange, rich green and bright yellow streak across the mountain, forming    4    is known as the most beautiful rainbow mountain.   

The beautiful landscapes    5     (create) by sandstone and minerals piling on top of one another over the years due to tectonic plate movements. Wind, rain, and time then carved the rock formations and rolling hills into    6     (vary) extraordinary shapes, including towers, pillars and valleys.   

    7    (declare) a UNESCO World Heritage site in 2010 and a national park in 2011, the landform has become a top tourist    8     (attract). The park features a series of boardwalks that allow visitors to walk around the colorful sandstone landscapes. There are viewing platforms    9     (special) designed, enabling tourists to get close to the hills and feast their eyes on the magnificent sights without damaging the fragile ecosystem. Shuttle bus service is available, making    10     easy for tourists to get around the park.

Regular exercise can increase your body's energy expenditure（能量消耗）and it is also a great way     1    （improve）your productivity and mental focus throughout the day. The increased energy levels that occur as a result of exercise     2    (be) also likely to lead to more active habits throughout the day, such as taking the stairs rather than the lift, or     3    (walk) to speak to workmates instead     4     emailing. This increased activity will then bring physical and mental benefits.

Physical activity can help us to improve the length and the quality（质量）of our sleep,     5    will in turn make further contributions to our health and wellbeing. While there is no absolute figure（绝对数值）we should aim for in terms of sleep time, most people will find that they fall somewhere between 6-9 hours a night. Quality is     6    (certain) more important than quantity.

Regular physical activity can help us to manage life's stress much     7    (well) as a distraction technique.

Monkeys do not like it when others get more food     1     they do, according to a new study.

Researchers from Yale and Harvard universities found Capuchin monkeys punish monkeys     2     get more food. "This sort of, 'If I can't have it, no one can' response is because     3     psychological spite (怨恨), and it was    4     (previous) thought unique to humans," said Kristin Leimgruber of Harvard University. She is a co-author of the research study. The researchers watched as some Capuchin monkeys     5     (give) more food than others. They found that monkeys getting the     6     (small) share pulled a rope to fold up a table holding the other monkey's bigger share.

Another lead researcher, Laurie Santas,     7     (explain) over email, "I think what we can conclude about humans is that some of our more embarrassing tendencies have relatively deep     8     (root)." Santos said the spiteful response was not present with another member of the ape species—chimpanzees(黑猩猩).

An earlier study, she said, showed chimpanzees would fold up the table of other chimpanzees     9     (steal) food from them. But they would not punish chimpanzees who just happened     10     (have) more food, Santos said. In other words, it was fine if another chimpanzee had more food as long as they did not steal it.
