【题目】Places, People and Property with Strutt & Parker

The world might seem focused on urbanization, but over the past five years of our Housing Futures research, we have seen the emergence of a new trend in housing the desire to move back to rural locations.

With advancements in technology, villages are now more connected than ever. Our Housing Futures research, focusing on The Village Revival, identified that 21% of respondents expressed a desire to move to a village, making it probably the most popular location for buyers. Those looking to move cited neighborhood safety (86%), space between neighbors (58%) and a strong community feel (48%) as key factors to leave cities and settle in rural location.

Figures show that England’s rural economy produces 210 billion of economic output. In fact, a quarter of all registered businesses are based in rural locations. The expansion of broadband and mobile communications has seen a greater rate of working from home in rural locations compared to urban areas. It seems that the same factors that once drove urbanization — improving economic and social conditions-are now inspiring the village revival.

So, if you’re thinking of moving to a more rural location, Strutt & Parker is well placed to help. Our agents take the time to really understand what you’re looking for.

【题目】Directions: Fill in each blank with a proper word chosen from the box. Each word can only be used once. Note that there is one word more than you need.

You're trying your best to enjoy an evening cookout, but a constant swarm of mosquitoes follows you from grill to poolside. The threat? A pierce to your skin, leaving behind an itchy red welt and possibly even a serious illness. As you swat madly at the pests, you notice that others seem completely unbothered. Could it be that mosquitoes prefer to bite some people over others?

The short answer is yes. Mosquitoes do 【1】 blood-sucking preferences, say the experts. "One in 10 people are highly attractive to mosquitoes," reports Jerry Butler, PhD, professor emeritus at the University of Florida. But it's not dinner they're sucking out of you. Female mosquitoes -- males do not bite people -- need human blood to develop 【2】 eggs. And apparently, not just anyone's will do.

Who Mosquitoes Like Best? Although researchers have yet to 【3】 what mosquitoes consider an ideal hunk (大块) of human flesh, the hunt is on. "There's a tremendous amount of research being conducted on what compounds and odors people exude that might be attractive to mosquitoes," says Joe Conlon, PhD, technical advisor to the American Mosquito Control Association. With 400 different compounds to examine, it's an extremely laborious process. "Researchers are just beginning to 【4】 the surface," he says.

Scientists do know that genetics 【5】 for an overwhelming 85% of our susceptibility to mosquito bites. They've also identified certain elements of our body chemistry that, when found in excess on the skin's surface, make mosquitoes swarm closer.

"People with high 【6】 of steroids or cholesterol on their skin surface attract mosquitoes," Butler tells WebMD. That doesn't necessarily mean that mosquitoes prey on people with higher overall levels of cholesterol, Butler explains. These people simply may be more efficient at processing cholesterol, the byproducts of which remain on the skin's surface.

Mosquitoes also 【7】 people who produce excess amounts of certain acids, such as uric acid, explains entomologist John Edman, PhD, spokesman for the Entomological Society of America. These substances can trigger mosquitoes' sense of smell, luring them to land on 【8】victims.

But the process of attraction begins long before the landing. Mosquitoes can smell their dinner from a(n) 【9】 distance of up to 50 meters, explains Edman. This doesn't bode well for people who emit large quantities of carbon dioxide…..Luckily, there are chemical-based mosquito repellents and the soybean oil-based repellent that can help to keep the bite at【10】.
