The surprising experiment I am about to describe proves that air is all aroud you and that it proves down upon you．Air pressure is a wonderful force．When you swim underwater, you can feel water push down your body．The air all around you does the same．However, your body is so used to it that you do not notice this ．The pressure is caused by a layer of air called the atmosphere．This layer surrounds the Earth , extending to about five kilometers above the Earth’s surface．
The following experiment is an easy one that you can do at home．But make sure that you are supervised , because you will need to use matches．Now for the experiment！
What you need
·A hard-boiled egg without the shell
·A bottle with a neck slightly smaller than the egg
·A piece of paper
·A match
Metheod
1) Check that the egg will sit firmly on the neck of the bottle．
2) Tear the paper into strips and put the strips into the bottle．
3) Light the paper by dropping a burning match into the bottle．
4) Quickly sit the egg on the neck of the bottle．
Result
Astonishingly,the egg will be sucked into the bottle．Your friends will be amazed when you show them the experiment．But be careful when you handle matches．
Why it happened
As the paper burns,it needs oxyen and uses up the oxygen(air) in the bottle．The egg acts as a seal in the neck of the bottle,so no more air can get inside ．This reduces the air pressure inside the bottle．The air pressure must equalize,so more air from outside must enter the bottle．The outside air pressure against the egg and then the egg is pushed into the bottle!The proves that air is all around and that it is pressing down on it．
53．When you do the experiment, why need you a person beside you?
A．You couldn’t place the egg on the bottle by yourself．
B．The egg needs to be shelled．
C．You need to use matches．
D．The bottle can’t sit firmly on the desk．
54．The purpose of doing this experiment is to prove ______．
A．air pressure is a wonderful force
B．water can push down your body when you swim underwater
C．the air pressure is not equalized around us
D．the earth is surrounded by a layer of air called the atmosphere
55．How did the egg put into the bottle？
A．The oxygen inside the bottle suckde the egg in．
B．It became solt without the shell．
C．The neck of the bottle was wide enough．
D．The outside air pressure forced it into the bottle．
56．The passage is ______．
A．an experiment report            B．a scientific story
C．a research report                 D．an interesting novel

Music died here last spring, or rather, it was killed by members of the school committee who ignored the importance of music and drama as part of the high-school curriculum.
The committee decided that teaching students how to take a standardized test is more important than a curriculum in which students can explore their interests in the arts as well as academics. Because the school system is running out of funding, it needs to make sure that students pass the mastery test or even more money will be lost. If students fail the state standardized test, it is not the fault of drama and music classes— they are failing because the “ academic” classes are not sufficient.
It is painful to think of how many students will be discouraged from singing, acting, and playing instruments because school programs are no longer offered. Many families cannot afford private music lessons, and many potential musicians and artists may not find their calling if they are not exposed to it in school. The fact that the school committee thinks the arts are not worth the investment will certainly make some students believe the arts are not worth their time or support and the cycle will continue.
Teaching for a test does not shape students into complete, well rounded people. It blocks the natural sense to create and express feelings through art— there is more to life than the analytical thinking that math and English provide. What happens after a test? Sure, a student might graduate, but they will have limited knowledge — certainly not a good preparation for the real world.
【小题1】Music and drama are not included in the high-school curriculum mainly because________.
