7 . Are you afraid of sharks, snakes or spiders? Most of us are.     1     Do you know mosquitos have killed many more humans than all wars in history? Mosquitos are the most dangerous creatures on earth to humans by a mile.

Female mosquitos actually need our blood to make eggs. They give us viruses and diseases that are extremely dangerous.     2    Just one mosquito buzzing (发出嗡嗡声) around your bed can keep you awake all night.

Now, there is a great way to stop mosquitos from annoying you ever again — without using any chemicals at all. It's called Mosquitron, a brand new type of bug catcher/killer. It's perfect for clearing your home of all the annoying and dangerous mosquitos!     3    

Instead of trying to keep the mosquitos away, it actually attracts them, then catches and kills them!     4     Next to the UV-PT light is a powerful fan that sucks the mosquitos through a one-way trapdoor (活板门). Once trapped in the drying basket, they are dried to death by the fan in a matter of 2 minutes.

    5     But when you consider that most devices need expensive refills and don't work for more than 10 minutes, this is a pretty good deal. Plus, it actually works! When you look at the rise in mosquito viruses and diseases and the number of deaths, $89 seems like a good deal for peace of mind that you are protected.

8 . They say, “Online retailers (零售商) try to show you things that you wouldn’t have discovered otherwise. But we don’t think it compares to the experience of walking into a store and seeing things you wouldn’t have seen otherwise.”

That’s hardly an old-fashioned view. One of the misunderstandings in retail is that because younger customers are comfortable with digital technologies, they’re less interested in shopping in person. In fact, researchers have found that both millennials (千禧一代) and the generation born after 1995 prefer brick-and-mortar shopping to buying online.

Now in the pandemic age, retailers are working on making ordering online and picking up at the store a seamless (无缝衔接的) process. And that could be just the start. Other mixed models will appear, especially as retailers get rid of delays from the system, says Kirthi Kalyanam, executive director of the Retail Management Institute at Santa Clara University in California. Amazon, which already provides free two-day delivery to prime members, now offers one-day delivery nationwide for a fee and same-day delivery on select items in several cities. Its Amazon Fresh grocery service lets shoppers choose delivery within two to three hours.

Stores will increasingly become places to show products rather than to store inventory (存货), says Mr. Kalyanam. Online retailers will re-create their online image in a real space: Think Apple stores or Lululemon. And consumers will have multiple ways to buy their goods. Stores might not even carry inventory, but promise to deliver your purchase from a nearby warehouse in a half-hour.
