During summer days, warmer temperatures bring pests like mosquitoes. Mosquitoes can cause lots of trouble for people.. They even can spread many serious diseases.
An easy way to protect yourself against mosquitoes is using repellents (驱虫剂). Joseph Conlon, an advisor of the American Mosquito Control Association, recommends using repellents that are registered with the Environmental Protection Agency, which ensures that they actually do no harm to humans. . But some repellents can provide 4-6 hours of protection if the quality of them is excellent.
Mosquitoes are also very weak. A slight wind from a fan can help keep them away from you. It turns out that many mosquitoes are not very good fliers..
Another way is to clear all the standing water (积水) every five days. Conlon explains that mosquitoes can produce young in water collected in areas as small as bottle caps. But they have a limited flight range, which means they can't travel far. "The best way to avoid them is to not have them around in the first place." he says. If you've got them in your backyard, it's because you're raising them in your backyard.. "If you can't avoid the standing water around your house, I suggest raising fish that will eat mosquito larvae (幼虫)."
. They've experimented with male mosquitoes containing some materials that stop females from producing larvae. "There are not a lot of companies producing new chemicals or treatments that we can use," a researcher of the experiment adds. "We need new technologies and products to get rid of mosquitoes."

Spilling coffee, juice or water on a laptop might seem like the end of the world, {#blank#}1{#/blank#}. Here's a five-step plan to rescue a laptop after a liquid spill.
Switch the laptop off

Remove excess liquid from the laptop
Remove excess liquid with a soft cloth or paper towels. Do not use a wiping motion as that just spreads the liquid further.

With the laptop facing away from you, move it from side to side and from front to back in a gentle rocking motion to help the liquid to escape from all four sides.
Use compressed air to dry the laptop
Make sure that you have removed all excess liquid. Then, if you have one, use a can of compressed air to help dry the laptop. {#blank#}4{#/blank#}. Keep the dryer moving all the time and hold it at least 20cm above the laptop.
Leave laptop to completely dry out
