10、mself impressive goals such as running six days in a row in the Sahara desert, which is considered the most tiring race of all ultra-marathons. These days hes exchanged the desert for the roads from Washington, DC, where he lives, to his hometown of Scranton, Pennsylvania. His 98-year-old grandmothe
11、r Ruth lives there and was isolated（隔离）while recovering from CO VID-19.His motivation wasnt just to give his grandmother, who was in a nursing home, a hug from afar. The athlete ran for a cause： to raise awareness of the isolation of the elderly during the pandemic(传染病).He left DCseven days earlier
12、and his race had a specific goal： to raise money to buy smart phones and tablets for elderly people isolated due to COVID-19, so that they could communicate with their loved ones.Ruths grandson, who affectionately calls her Nana, was greeted with cheers by the personnel at the center where his grand
13、mother is staying. From the fourth floor, Ruth greeted him from the window. Dozens of workers from the Allied Services Skilled Nursing and Rehabilitation Center applauded as he crossed the finish line. Breathless but smiling, he pointed to Nana s fourth-floor room, where she was watching him through
14、 the window.Then they talked on their cell phones. Corey had a microphone in his hand so those around him could hear the conversation, in which he thanked the Centers staff, expressed thelove that he and so many other people had for Ruth, and assured her that he had always been confident in her stre

18、 support. DSpiritual comfort. Are you having difficulty falling asleep? Try drinking a glass of warm milk. If that doesnt work, listen to beautiful soft music. Still no luck? Try thinking about sheep jumping over a fence. If you are still awake, take a sleeping pill. But people who take pills often
19、become dependent on the drugs. So you lie awake knowing that the new workday will soon arrive. If you have been in such condition for at least one month, you may have primary insomnia（失眠症）. A new study has found that you might fall asleep more quickly and stay asleep longer if you try cerebral hypot
20、hermia. It is not a complex medical process. It just means cooling down your brain. Eric Nofzinger and Daniel Buysse from the University of Pittsburgh Medical School led the study. They examined twelve people who had sleeping problems. Twelve others had no sleeping problems. Each of them wore a soft
21、 plastic cap on their head at bedtime.The caps had tubes inside filled with water. The researchers moved the water through the tubes and then changed the temperature of the water. Other studies showed that people who had sleeping problems often had more chemical reactions in the front of their brain
22、s. The researchers thought cooling down the brain might help. On the first two nights of testing, the patients wore caps with no water. On the next two nights, the caps were worn, but the water was not cooled. Then the researchers cooled the water a little for another two nights. On the final two ni
23、ghts of the study, the temperature of the water was made much cooler.The researchers found that the water caps didnt help the patients until the temperature was about 14. Most of the patients fell asleep faster and slept better when the coolest water was moving around their heads. Dr. Nofzinger and
24、Dr. Buysse noted that this was only the beginning of the brain temperature study. But they believed they had discovered something important that needed more research.8What is the purpose of Paragraph 1?ATo ask readers a question.

27、0, the fifth generation of wireless technology is expected to be widely used throughout the world. The new network, called 5G, promises to give faster speeds and a higher capacity for the use of more devices. However, while some companies are competing to be the first to deliver 5G to the consumer,
28、the environmental influences of the new network are being overlooked.There is some evidence that the new devices and technologies associated with 5G will be harmful to ecosystems. The main component of the 5G network that will affect the earths ecosystems is the millimeter waves. The millimeter wave
29、s that are being used in developing the 5G network have never been used at such scale(规模)before. Studies have found that there are some harms caused by these new technologies.The millimeter waves, specifically, had a detrimental effect on birds. In a study, researchers observed that after exposure t
30、o radiation from a cell tower for just 530 minutes, the eggs of sparrows were disfigured. The disfiguration of birds exposed for such a short amount of time to these frequencies(频率)is significant considering that the new 5G network will have a much higher density(浓度)of base stations(small cells) thr
31、oughout areas needing connection. The potential dangers of having so many small cells all over areas where birds live could threaten their populations survival.Additionally, it was found that cellular devices were linked to many disturbances in the ecosystems of bees. In this study, beehives exposed
32、 for just ten minutes to 900MHz waves fell victim to colony collapse disorder(蜂群崩坏症候群). Bees are an incredibly important part of the earths ecosystem. Around one-third of the food produced today is dependent on bees for pollination(授粉), making bees are a vital part of the agricultural system.The impact that the cell towers have on birds and bees is important to understand, because all ecosystems of the earth are interconnected. If one c
