Why I need to use write() in here

instead of use raw my_servo(pos)

my_servo is the name of your servo object
write() is a function in the Servo library that moves the specified servo to the position given
Hence my_servo.write(pos);

you can see the public API for the Servo class in its .h file

          Servo();
          uint8_t attach(int pin);           // attach the given pin to the next free channel, sets pinMode, returns channel number or INVALID_SERVO if failure
          uint8_t attach(int pin, int min, int max); // as above but also sets min and max values for writes. 
          void detach();
          void write(int value);             // if value is < 200 its treated as an angle, otherwise as pulse width in microseconds 
          void writeMicroseconds(int value); // Write pulse width in microseconds 
          int read();                        // returns current pulse width as an angle between 0 and 180 degrees
          int readMicroseconds();            // returns current pulse width in microseconds for this servo (was read_us() in first release)
          bool attached();                   // return true if this servo is attached, otherwise false

Show us the sketch to do so.
