1 . As the effects of climate change become more disastrous, well-known research institutions and government agencies are focusing new money and attention on an idea: artificially cooling the planet, in the hopes of buying humanity more time to cut greenhouse gas emissions.
That strategy, called solar climate intervention (干预) or solar geoengineering, involves reflecting more of the sun’s energy back into space — abruptly reducing global temperatures in a way that imitates the effects of ash clouds flowing out from the volcanic eruptions. The idea has been considered as a dangerous and fancied solution, one that would encourage people to keep burning fossil fuels while exposing the planet to unexpected and potentially threatening side effects, producing more destructive hurricanes, wildfires floods and other disasters.
But. as global warming continues, producing more destructive hurricanes, wildfires floods and other disasters, some researchers and policy experts say that concerns about geoengineering should be outweighed by the imperative to better understand it, in case the consequence of climate change become so terrible that the world can’t wait for better solutions.
One way to cool the earth is by injecting aerosols (气溶胶) into the upper layer of the atmosphere. where those particles reflect sunlight away from the earth. That process works, according to Douglas MacMartin, a researcher at Cornell University.
“We know with 100% certainty that we can cool the planet,” he said in an interview. What’s still unclear, he added, is what happens next. Temperature, MacMartin said, is an indicator for a lot of climate effects. “What does it do to the strength of hurricanes?” he asked, “What does it do to agriculture production? What does it do to the risk of forest fires?”
Another institution funded by the National Science Foundation will analyze hundreds of simulations of aerosol injection, testing the effects on weather extremes around the world. One goal of the research is to look for a sweet spot: the amount of artificial cooling that can reduce extreme weather events without causing broader changes in regional rainfall patterns or similar impacts.

2 . The term ''helicopter parents'' refers to ''a style of parents who are over focused on their children''.
Helicopter parents are always making a big effort to provide children with every opportunity to succeed, from baby steps at age I, homework at age 8, college application at age 18, employment issues at age 25 to family problems at age 30, 40 or even older. They constantly (不断地) shadow the child, always directing his behavior, allowing him zero alone time.
Helicopter parenting can develop for a number of reasons. Worries about the economy, the job market, and the world in general can push parents toward taking more control over their children’s life in an attempt to protect them. Adults who felt unloved or ignored as children can overcompensate (对……补偿过多) with their own children. When parents see other over-involved parents, it can cause a similar response. They feel that if they don t involve themselves in their children’s lives, they are bad parents.
The main problem with helicopter parenting is that it can backfire. To give an example, the house where Mary lived with roommates was broken into and things were stolen. Mary called the landlord to install (安装) an alarm system, but before she could finish the negotiations (协商), her mother rushed in and demanded action. ''I felt like my mother ruined my communication with our landlord. We could have gotten it done ourselves. She was well intended but only made me feel annoyed and defeated, '' says Mary.
Obviously, overparenting is motivated with the idea of doing good things but it does the exact opposite. In the long run parents are in fact damaging their child's basic skills to deal with matters independently. It makes the child feel lacking in confidence, less competent in dealing with the stresses of life on their own. They're winning the battle, but in fact losing the war.
