The Singing Sands Mountain(鸣沙山)is located in Dunhuang in    1     (west)China. Whether you walk through the quicksand    2    slide down a sand mountain, you can hear loud noises from beneath your feet. That’s    3    it is named“The Singing Sands Mountain”. There is a spring lying between the tall sand mountains. This spring, which looks like a crescent moon(月牙),    4    (exist) for thousands of years and has never dried up. The formation and continuous existence of the Crescent Spring are greatly related to its topography (地势).

The flowing water gathers here along the landform and overflows through a porous(可渗透的) geological layer    5    (form) the Crescent Spring. Although its     6    (extreme) dry here, with the annual evaporation being more than 60 times that of the annual precipitation, the stable water source ensures a sustainable water supply to the spring.It’s also due     7    the low-lying terrain(低洼).Whenever there’s a sandstorm, it forms an upward spiral air flow between the surrounding sand mountains, sending the sand at the foot back to    8    top of the sand mountain,and saving the Crescent Spring from    9    (wallow)by quicksand.

The ancient Silk Road once passed by the Crescent Spring. And today, it has become a romantic paradise for    10     (visit).

    1    （see） from outer space, Earth is a blue planet, due to the fact that the ocean covers over 70 percent of its surface. According to a new study published in the journal Science, the ocean plays a great role in     2    （slow）down global warming. It is “    3    important buffer（缓冲物）”,    4    The New York Times put it.

The oceans can absorb 93 percent of the heat trapped by the greenhouse gases     5    humans release into the atmosphere. And the other 7 percent     6    （absorb)by the air, land and ice caps, according to the Guardian.

“If the ocean wasn’t absorbing as much heat, the surface of the land would heat up much     7     （fast） than it is right now,” said professor Malin L. Pinsky at Rutgers University in the US. “In fact, the ocean is saving us from rapid warming right now.”

However, the ocean itself, as Discover Magazine noted, is heating up 40 percent faster on average than the United Nations     8    （believe） five years ago. That means if the ocean temperatures increase     9    this speed, the high water temperatures “will kill off marine ecosystems, raise sea     10     (level) and make hurricanes more destructive （破坏性的）”, the Guardian reported.

Like millions of other people, Mr Griffin, who is head of IT for marketing agency Rise at Seven,     1    (get) his own dog during the pandemic.

With most of us     2     (work) from home at the time of lockdowns, there was    3    sharp increase in pet ownership as people wanted companionship (陪伴). As bosses require staff to return to the office    4    least a few days a week, having a pet dog can become a problem. You have to find a friend or relative     5    (look) after it, or pay for expensive doggie day care. Or even try to get a new job    6    allows you to continue to work from home all the time.

    7    was to help employees such as Mr Griffin more easily return to the office after the pandemic that Rise’s bosses decided to let everyone bring in their dogs. Mia King, one of the firm’s    8     (executive), says that having dogs at work has actually made staff work harder,     9     than being a distraction (使人分心的事物). Dogs make everyone happy, and cheery staff are    10     (productive) anyway.

It is hard for me to practice kindness to people as I live in a very distant area and often go many days without     1     (see) anyone, but I can practice kindness actually, with my husband and     2     (animal). I volunteer at the local animal shelter.

Several months ago, an upper breathing virus was spreading through the cats. One very young cat     3     had been operated on was especially sick. I told the shelter that I would take the cat to the animal hospital and would pay its bills and keep it for some time.

I worked with the cat for over a week, getting it     4     (take) good care of, giving it medicines, worrying about it, and loving it. It was so sick.     5     (frank), I thought it was going to die because the doctor did not give any promises. Later, I went to deal     6     my family business and we didn't go there for     7     long time. But I hoped that it could get better soon.

About a week ago, I found the cat on the side of a road with its two baby cats although it was still just a little cat     8     (it). To my great excitement, the wonder I was expecting has happened. It has overcome the     9     (ill). Well, my husband and I decided that it should     10     (give) a forever home. Now it lives quietly in my house with its two babies.
