     Barbara Morgan's lifelong dream has always been to travel into space.  On August 8,   2007,   her

wish came true.  The former teacher was one of seven crewmembers on the Space Shuttle Endeavour,   which flew into space from NASA's Kennedy Space Station in Florida.  

      Morgan taught at a primary school in Boise from 1975 to 1998 - with some time off for astronaut

training.  In 1985,   she was chosen as a backup for Christa McAuliffe,   who was to be the first teacher

in space.  On January 28,   1986,   the Space Shuttle Challenger exploded just 73 seconds after takeoff

killing McAuliffe and the other six crewmembers.  

      After the Challenger accident,   Morgan continued to teach.  In 1998,   she was asked to become

an astronaut.  Morgan's mission aboard Endeavour includes overseeing the move of 5,   000 pounds of

goods from the shuttle to the International Space Station and operating the shuttle's robotic arm.  

      Morgan gave students an unusual class after she was in space.  Morgan's outofthisworld class was

broadcast live on NASA television.  Her husband Clay Morgan said he couldn't help but smile as he

watched her talk to students.  "I'm just so proud of her and how she's going to do all this and do the

work of an astronaut as well as a teacher,   " he said.  "She just kept telling me how unbelievable it was

to be in space and I think it's much better than she expected. " One student asked Morgan how being a

teacher compared to being an astronaut.  "We explore,   we discover and we share,   " she said.  "The

great thing about being a teacher is you get to do that with students,   and the great thing about being an

astronaut is you get to do it in space.  These are both wonderful jobs. "

      The 25minute questionandanswer meeting also included the astronauts entertaining students by

swallowing floating juice bubbles and playing with PingPong balls.

阅读以下函数说明和C语言函数，将应填入 (n) 处的字句写在对应栏内。
[说明1]
函数void fun(char^*w,char x,int^*n)用来在w数组中插入x，w数组中的数已按由小到大顺序存放，n指存储单元中存放数组中数据的个数，插入后数组中的数仍有序。
[C函数1]
void fun(char^*W,char x,int^*n)
{ int i,P;
p=0;
w[^*n]=x;
while(x＞w[p]) (1) ;
for(i=^*n,i＞p;i--)w[i]= (2) ;
w[p]=x;
++^*n;
}
[说明2]
函数void revstr(char^*s)将字符串s逆置。例如：字符串“abcde”，经过逆置后变为“edcba”。
[C函数2]
void revstr(char^*s)
{ char^*p,c;
if(s==NULL)return;
p= (3) ; /^*p指向字符串s的最后一个有效字符^*/
while(s＜p){ /^*交换并移动指针^*/
C=^*s;
(4) =^*p;
(5) =c;
}
}
