问题      Some call it the Smart Shooter, a new rifle for American infantry troops that is two weapons in one, is accurate up to 1,000 yards and in  【21】______   fires  【22】______   corners. Its message to enemies is that they can run but they can’t hide.
      Still in the development phase, the rifle for 2006 has just been  【23】______   off with great  【24】______   by the Pentagon to members of Congress who will be asked to  【25】______   the money. The makers, Alliant Techsystems,  say that the weapon will revolutionize  【26】______   combat much as the machine gun.
      Pentagon jargon has given the new gun a(an)  【27】______   title: the Objective Individual Combat Weapon.  【28】______   one trigger, the rifle can fire a standard 5.56mm Nato bullet and a 20mm high explosive shell that will burst in the air. It can  【29】______   shrapnel behind,  【30】______   or even from the side of enemy troops who have taken  【31】______   behind a building.  The shell can be  【32】______   to explode after a short delay. The weapon’s 1,000 yard accuracy is twice  【33】______   of other rifles, made possible by a laser system built into the sight. This rangefinder fixes the target, measures the distance and passes it along to a computer chip in the shell.
      The gunsight has an infrared lens for night  【34】______   . It can also have video camera with a zoom lens that is linked to a video display attached to the soldier’s helmet, allowing him to aim  【35】______   without exposing himself to enemy return fire. But there are snags still be  【36】______   out. Two men were  【37】______   when a shell burst in a barrel during firing tests. The rifle weighs more than 18lb. There are questions whether its electronic innards will be rugged enough for rain, snow and difficult  【38】______   .
      Michael Klare, a professor of peace and world security issues and a board member of the Arms Control Association, says that the Pentagon is seeking this combination of firepower and automation to compensate for the uncertain aim of GIs. He said: "Soldiers won’t have to worry about careful steady aim. They’ll just look  【39】______   the viewfinder and  【40】______   the trigger."
