《昆虫记》是优秀的科普著作,也是公认的文学经典。鲁迅把它奉为“讲昆虫生活”的楷模。在作者(姓名)          笔下,         像个吝啬鬼,身穿一件似乎“缺了布料”的短身燕礼服;          “为它的后代作出无私的奉献,为儿女操碎了心”;而被毒蜘蛛咬伤的         会“愉快的进食,如果我们喂食动作慢了,它甚至会像婴儿般哭闹”。

Fire fighting is a serous matter, knowing what to do during a fire can save people’s lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators.
From the lower floors of building, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury.
The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about twice the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing.
