我国发射神舟号飞船时，先将飞船发送到一个椭圆轨道上，其近地点M距地面200km，远地点N距地面340km。进入该轨道正常运行时，其周期为T1,通过M、N点时的速率分别是V1,V2。当某次飞船通过N点时，地面指挥部发出指令，点燃飞船上的发动机，使飞船在短时间内加速后进入离地面340km的圆形轨道，开始绕地球做匀速圆周运动,周期为T2,这时飞船的速率为V3。比较飞船在M、N、P三点正常运行时（不包括点火加速阶段）的速率大小和加速度大小，及在两个轨道上运行的周期,下列结论正确的是

A．

B．

C．

D．

An Experiment
Materials: Newspaper, ‘ACE’ hardware ruler (1/8 “think”), a flat table.
Purposes: We’ll show that there is air pressure pushing on us, from every direction while we’re on this Earth.


 
Procedure:

First put a thin ruler on a flat table with a little
less than half of it hanging off the edge of the table
(see the drawing below). Next place a sheet of newspaper
over the ruler flat against the table. Make sure to have
as little air as possible under the paper so that the fold line of the newspaper is at the ruler. Then quickly strike the end of the ruler hanging off the edge of the table. If you strike it quick enough, the ruler will break near the table edge.
What’s going on?
The Earth is covered in a layer of air that is nearly 80 miles thick and at sea level (the bottom) exerts or ‘pushes’ hard almost 15 pounds of pressure per square inch. That means that a full sheet of newspaper laid out flat has nearly 9,300 pounds of air above it.
When you break the ruler above, you are able to break it because of the 'heavy' air pushing down on the paper while you quickly strike the ruler. At first the table is pushing back on the paper, and if you move the ruler quick enough, other air around the edges of the paper can't get under the paper fast enough, so you are trying to lift that 9,300 pounds with the ruler! Some air gets under the paper, but not enough, so the ruler breaks.
1．By doing the experiment, we may realize         .
A．that air exits everywhere
B．why there are directions
C．that we live with air pressure
D．how air helps on the earth
2．How many steps are there in this experiment?          .
A．2      B．3       C．4       D．5
3．The underlined word “exert” probably means       .
A．cover completely            B．advocate actively    
C．influence gradually  D．press heavily
4．The ruler breaks under a quick strike mainly because of          .
A．the air pressure on the newspaper   B．the heavy weight of the newspaper
C．the heavy weight of the flat table    D．the strong power used on the ruler
