20、What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage．

Escaping a fire is a serious matter．Knowing what to do during a fire can save your life．It is important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not lifts．

From the lower floors of the buildings, escaping through windows is possible, learn the best way of leaving by windows with the least chance of serious injury．

The second floor window is usually not very high from the ground．An average（平均高度的）person，hanging by the finger—tips will have a drop of about six feet to the ground．It is about the height of an average man．Of course，it is safer to jump a short way than to stay in a burning building．

Windows are also useful when you are waiting for help．Be sure to keep the door closed．Or 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 leaked（渗）into the room．

On a second or third floor，the best windows for escape are those that open onto a roof．From the roof a person can drop to the ground more safely．Dropping onto cement （水泥）might end in injury．Bushes（灌木丛）and grass sail help to break a fall．

19、Waste can be seen everywhere in the school．Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom．They say they can afford these things．But I don’t agree with them．

Waste can bring a lot of problems．Although China is rich in some resources, we are short of others, for example, fresh water．It is reported that we will have no coal or oil to use in 100 years．So if we go on wasting our resources, what can we use in the future and where can we move? Think about it．I think we should say no to the students who waste things every day．Everybody should stop wasting as soon as possible．

In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on．Little by little, everything will be changed．Waste can be stopped one day, if we do our best．
