PHP最近推出新版本PHP7.0，但是很多开源网站对PHP7.0可能会出现小问题，例如 Wordpress的Slider Revolution不支持php7.0，黑与白科技温馨提示先不要升级PHP，先保持原有的php5.6版本，以免网站出错。

It is a known fact that no matter where you are or where you go, you are likely to encounter a pretty good number of mosquitoes. Sometimes repellents may not work for you, as they are only likely to repel these flying insects for a few hours. It is a wise move to invest on a mosquito trap instead. Traps are advisable for use in your home, especially if it is apparent that these flying insects have already established your lawn as their breeding ground.
