1 . From the moment you open your eyes in the morning, you can feel sweat (汗水)running down your body, even if you’re barely moving at all. That’s what most people in China felt like this summer. In fact, the entire northern hemisphere(半球 )saw high temperatures in July. The Arctic Circle(北极圈) was no exception(例外). Temperatures in the city of Norilsk, which is in the Arctic Circle, reached a record high of 32 ℃, The Atlantic reported. Temperatures there are usually just 10 ℃ at this time of the year.
The heat wave in the Arctic is mainly a long-term result of global warming, according to the Chinese Academy of Meteorological Sciences. In fact, while the whole world is getting warmer, the Arctic is warming twice as fast as the rest of the planet. This is called the polar amplification effect(极地放大效应).
The most direct impact(影响) of Arctic warming is the melting of Arctic ice. According to NASA, Arctic sea ice is now disappearing at a rate of 13. 2 percent every 10 years. NASA said that if this continues, the Arctic will have no ice by the year 2040. This has put some Arctic animals, like polar bears, in danger. The ice that the bears live on has shrunk(缩小), the Toronto Star reported.
Melting ice can also cause sea levels to rise in the long term. Since 1993, sea levels have risen at a rate of 3. 2 cm every 10 years, the Guardian reported. Some countries, such as Tuvalu(图瓦卢) in the South Pacific Ocean and Maldives(马尔代夫) in the Indian Ocean, are at risk of disappearing into the sea.

2 . Nearly one in four Americans made money over the last 12 months by using their personal computers or other devices connected to the Internet. The Pew Research Center, an independent research group in Washington, found that people are using the Internet to find extra work. They go online to sell things such as used books and furniture or they offer to provide services such as babysitting, house cleaning or computer repairs.
Pew found that income earned on the Internet can come in many forms. Some said they had jobs that paid a few pennies each to take surveys. In these surveys, people are asked for their opinions of different products or well-known people. About two percent of Americans earned money from ride-sharing companies such as Uber and Lyft. When drivers are ready to pick up passengers, they use their ride-share company’s app. The computer program lets them know when passengers are ready to be picked up and how to reach them. Some people make their homes, apartments, or rooms inside their homes, available for money to people visiting their cities.
About 60 percent of people say the income they earn is important to them. But just one in five people who sell things online say the income is enough to be important to their lives. Only 16 percent believe doing online work will lead to a meaningful career. But 37 percent say the extra income earned from online jobs helps them make up for shortages in money.
The number one reason people gave for taking online jobs was that the work gave them something to do and was fun. What kind of people work online or use online devices to find work?The answer appears to be: mostly people who already have jobs.
