After visiting a Haringey tower block, the Metropolitan Police commissioner Ian Blair claimed that people now feel as safe as they did 25 years ago．
Do you agree with Sir Ian’s rosy view of society?
Do you feel safe enough to leave your doors unlocked where you live?…

I lived in Devon for three years, and can honestly say that in the village where I lived it was safe to leave the front door unlocked．But a London district?What planet is Ian Blair on?What decade is he in?
I’m not one of these people who think that Britain is slipping into a deep hole, but I am realistic enough to understand that wherever you find a large population you will find crime．
The idea that we can measure society’s downfall by how safe it is to leave the door unlocked is misleading, anyhow．It’s a little like the recent announcement that street crime has increased in recent years．Yes, it has, but the majority of people now walk around with half a branch of Dixon’s in their pockets-mobile phones, I-Pods．Of course, street crime is going to increase．
Funnily enough, there was hardly any car theft in the 19th century!!!
The same goes for houses．A hundred years ago your house may have contained a little jewelry, some furniture, and some small cash in a biscuit tin．Now even working class households are equipped with computers, DVD players, wide-screen televisions-all of which can be carried out in a matter of minutes．
I’m not speaking for the scum(渣滓)who choose to break into people’s houses and rob them of their hard-earned belongings, but it does put things into context．
Yes-we have to lock our front doors, and yes, it is a shame that we can’t trust everyone, but if we’re honest with ourselves, those of us living in cities never could trust absolutely everyone．

To extinguish(熄)different kinds of fires, several types of fire extinguishers(灭火器)have been invented．They must be ready for immediate use when fire breaks out．Most portable(手提式的)kinds operate for less than a minute, so they are useful only on small fires．The law requires ships, trains, buses and planes to carry extinguishers．
Since fuel, oxygen(氧气)and heat must be present for fire to exist, one or more of these things must be removed or reduced to extinguish a fire．If the heat is reduced by cooling the material below a certain temperature, the fire goes out．Water is the best cooling material because it is low in cost and easy to get．
Another method of extinguishing fire is by cutting off the oxygen．This is usually done by covering the fire with sand, steam or some other things．A blanket(毯子)may be used to cover a small fire．
A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel．
The method that is used to put out a fire depends on the type of fire．Fires have been divided into three classes．Fires in wood, paper, cloth and the like are called C1ass A fires．These materials usually help keep the fire on．Such fires can be stopped most easily by cooling with water．
