3 . It’s no secret that sleep is important to your overall health, but a lack of sleep could have great effects on your heart, a new study shows. The researchers said people with insomnia(失眠症)are more likely to have a heart attack.
Insomnia is the most common sleep disorder in the US, the researchers wrote in their report, noting that 10% to 15% of people in the US struggle with it. The meta-analysis of previously published research suggests that the potential association between insomnia and heart attack risk is strongest in women.
Dr. Martha Gulati, director of prevention at the Cedars-Sinai Smidt Heart Institute, said that most of her patients are women and that insomnia is a noted risk factor for women who have had any form of ischemic heart disease. “We see it probably in 1 in 10 patients in the United States,” said Gulati, who was not involved in the new research. “It is my impression that almost everyone experiences insomnia at some point in their life. The estimate is that 1 in 2 adults experience it at some point in their life, maybe in the short term because of stressful moments.”
For their analysis, the researchers defined insomnia as a sleep disorder with three main symptoms(症状): Difficulty falling asleep, difficulty staying asleep and waking early and being unable to fall back asleep.
The study also found an association between increased heart attack risk and how long a participant slept each night. Those who slept five hours or less had the highest association with heart attack risk and were 1.56 times more likely to have a heart attack than people who slept seven or eight hours. Longer sleep duration wasn’t always more protective. The study found that people who slept six hours a night had a lower risk of a heart attack than those who slept nine hours or more. “A lot of studies have pointed somewhere between seven and eight hours of sleep being the magic number for us,” another researcher said. “There is obviously variability for everyone, but too much sleep is rarely the issue.”

5 . Today, people use the Internet to shop, play games, make friends and read the news. Many young people can’t imagine life without it.
In 1957, the United States was in the middle of the Cold War. The Soviet Union (苏联) had sent up the first satellite (卫星), named Sputnik, into space. This meant the Soviets were ahead of the U. S. in technology. Americans were afraid.
The biggest change in the way that people use the Internet came in 1992. For the first time, the Internet was opened to the general public, creating what is now known as the World Wide Web.
A.The network took more than ten years to develop. |
B.Soon, people began finding all kinds of different things they could do on the Internet. |
C.Most older people, on the other hand, think the Internet is only 10 or 15 years old. |
D.People began to be fond of the Internet. |
E.They didn’t know what to do. |
F.The Internet then became available to colleges all over the United States and to scientists across Europe. |

8 . With its Victorian charm and windswept beauty, Block Island appeals to both outdoorsy travelers who want to hike, bike, boat and explore and to those who simply want to abandon reality back on the mainland.
See Mohegan Bluffs
As dramatic as any scenery in New England, the Mohegan Bluffs are 150-foot clay cliffs on the south side of Block Island. Unforgettable Atlantic Ocean views await those who descend a wooden staircase more than 140 steps to the sliver of sand below. The only protection you’ll need when you go to this spot is sunscreen.

10 . According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.
Solar developers want to put up panels as quickly and cheaply as possible, so they haven’t given much thought to what they put under them. Often, they’ll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.
“Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE)project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).
Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.
Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that’s going on in the landscape,” says Macknick.
