(vary) based on many things, but it can be such a huge amount that it can bury the bottom of a slope in dozens of feet of snow.
Avalanches 2. be caused by natural things. For example, new snow or rain can cause built-up snow to loosen and fall down the side of a mountain. Artificial triggers（诱发因素）can also cause avalanches. For example, snowmobiles, skiers, and explosives 3. (know) to lead to avalanches.
Avalanches usually occur during the winter and spring, 4. snowfall is greatest. As they are dangerous to any living beings in their path, avalanches have destroyed forests, roads, railroads and even entire towns. Warning signs exist that allow experts to predict -- and often prevent -- avalanches from 5.
(occur). When over a foot of fresh snow falls, experts know to be on the lookout for avalanches. Explosives can be used in places 6. massive snow buildups to trigger much smaller avalanches that don’t pose a danger to persons or property.
When deadly avalanches do occur, the moving snow can quickly reach over 80 miles per hour. Skiers caught in such avalanches can be buried under dozens of feet of snow. 7. it’s possible to dig out of such avalanches, not all are able to escape.
If you get tossed about by an avalanche and find yourself 8. (bury) under many feet of snow, you might not have a true sense of which way is up and which way is down. Some avalanche victims have tried to dig their way out, only to find that they were upside down and digging 9. farther under the snow rather than to the top!
Experts suggest that people caught in an avalanche try to dig around you 10. (create) a space for air, so you can breathe more easily. Then, do your best to figure out which way is up and dig in that direction to reach the surface and signal rescuers.

Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
People choose to become entrepreneurs( 创 业 者 ） for a wide variety of reasons. One important reason is, of course, financial reward. If you own your own business and it becomes successful, you can reap huge financial rewards. And as an entrepreneur, dependent on how much your boss decides to give you; ifs limited only by the success of your business. And speaking of bosses, not having a supervisor is another major advantage of becoming an entrepreneur.
Entrepreneurs are often independent thinkers who want to be in charge of projects, rather than having others tell them what to do. They often have big dreams that that they want to pursue rather than making someone else’s dream come true. For many entrepreneurs, starting a business is a way of solving a problem or helping people receive something they need. It’s a way to change the world for the better.
Being an entrepreneur isn’t easy, however, nor is it always fun. Entrepreneurs often have to work long hours, especially early on when they’re trying to get their businesses off the ground. that’s the reason entrepreneurs need to have a strong work ethic( 伦 理 ).Employees can work 40 hours a week and then stop, but for an entrepreneur, there’s no end in sight.
That’s why another feature of successful entrepreneurs is passion; they have to be excited about what they’re doing to be willing to work hard for it. Entrepreneurs also need good communication skills to pass on that passion to others. That’s important for finding investors, getting people to buy products and attracting employees.
Entrepreneurs also need to be creative people who are able to find solutions to problems they encounter. This is important from the very beginning, when the entrepreneur comes up with an initial concept of a business. But even after that initial step, creative thinking is continually necessary to adapt to changing situations and to solve problems that come up.

Whether you’re on social media or sending a text message, you encounter emoji (表情符号)regularly. 1. While most people’s enthusiasm for emoji increased in the smart- phone era, Japan has been crazy for emoji since 1999. Designer Shigetaka Kurita invented emoji for a Japanese phone company 20 years ago as a way to make it easier to express ideas in a short message. The word emoji can be translated as “picture character” from Japanese. After the release of Kurita’s emoji, rival phone companies in Japan began creating their own emoji. Many emoji on our digital devices today are imported from Kurita’s original set of emoji.
Japan’s love for emoji continued well into the 2000s before the rest of the world discovered them. Apple Inc. officially introduced an emoji function in their software in 2011. Soon, other phone companies from around the world made it easier for their customers to use emoji 2..
As you scroll (滑动）through your phone, you can see the wide selection of available emoji. More than 2,000 emoji are in existence now, with more being released each year. These numbers show the popularity and demand for emoji.
Why? Because words alone can’t convey the complete meaning of a digital message. In digital communication, emoji express a tone or mood. More than 90 percent of people online use emoji especially ones that show emotion like hearts and smileys. 3.. For example, they might send a red heart emoji as a response that they really like something instead of writing, “I love that.”
Some emoji are also abstract enough for people to use in any way they like. You can send an emoji as an inside joke, which is only understood between you and your friend.
4.. Nor do they belong to a specific culture. You and I give emoji meaning, because emoji is a language that belongs to all of us.
A.You may find these colorful symbols unavoidable as they’ve become a language of their own
B.People can send emoji instead of writing words to participate in a conversation
C.No wonder emoji use is becoming more and more popular in various fields
D.Today, emoji use is a standard feature in digital communication
E.But not all the people show interest in emoji especially elder ones
F.Unlike most words, there isn't a certain definition for each emoji
5G, the fifth generation of wireless, promises lightning-fast download speeds and could lay foundation for high-tech advancements like self-driving cars. But like many new technologies, it's causing concern about potential health issues.
The first generation of wireless introduced mobile phones, and 2G brought texting. 3G laid the groundwork for smart-phones, and 4G allowed video streaming and more. 5G is expected to download data 20 times faster than its predessor(前任)，and some experts argue it could be much faster.
Too much of a good thing?
It's not just about streaming data faster, it's about streaming more of it. On a 5G network, a user can download a movie instantly, and data will flow between connected objects without delay. The amount of data people use on mobile devices has gone up 40 times since 2010 and is only expected to increase. 5G networks are wireless companies attempts to satisfy that demand.
Uncertain effects
The untested nature of 5G, and the extensiveness of its infrastructure( 基础设施） has some worried that the increased exposure could have serious health effects. Wireless safety advocates（倡议人士）have called for more studies on the effects of the exposure, and one group is trying to stop the installment of 5G networks in Chicago's neighborhoods.
The federal government has safety rules that wireless companies must obey that limit human exposure to radio waves, including frequencies uses with 5G.
Wireless industry association CTIA says typical exposure to 5G infrastructure is comparable to Bluetooth devices and baby monitors, and there is no scientific evidence of negative health effects.
Still, assurances from government agencies and industry operators are not enough for Chicago resident Judy Blake. Additional studies on 5G’s health impacts likely wouldn’t soothe her either. She said, “People can't choose whether or not to be exposed to this radiation.”
“I don’t need another test. The only test that’s going to happen now is people’s lives,” said Blake, 67.
Only time will tell?
Though little is known about the long-term health impact of the millimeter waves that 5G operates on, some research has shown short-term exposure could be problematic, said Joel Moskowitz, a public health expert at the University of California at Berkeley.
The eyes and sweat glands(腺体）are among several body parts studies have shown could be at risk. Moskowitz said. Insects and plant life could also be affected, he added.
The millimeter waves used in SG are absorbed by the upper layers of skin, potentially causing the temperature of the skin to rise, said Suresh Borkar, senior lecturer in the Department of Electrical and Computer Engineering at the Illinois Institute of Technology. The effects of extended rises in skin temperature “become a big unknown,” he said.
This isn't the first time people will come into contact with millimeter waves: They're also used in airport body scanners, said Lav Varshney, assistant professor of electrical and computer engineering at the University of Illinois at Urbana-Champaign. Still, it's the first time the high- frequency waves will he used on such a scale, and concerns surrounding new technologies are common throughout history.
“When cars first started replacing horse-drawn carriages, people were afraid of what the health impacts of traveling at high speeds would be,” Varshney said. “There has always been occurrence of this fear.”
