In Journey to the West, the Monkey King often turns into a bug and spies on monsters. Today, scientists are trying to turn the story into reality by {#blank#}1{#/blank#} (make) robot bugs. Would you like to know what they {#blank#}2{#/blank#} (be) like?

    Robot bugs are small robots that {#blank#}3{#/blank#} (look) like bugs. People can use them {#blank#}4{#/blank#} (take) pictures in dangerous areas, follow bad guys, or help find survivors (幸存者) in broken buildings.

    Work on robotic bugs {#blank#}5{#/blank#} (start) since World War II. Today they have been greatly improved.

    Harvard University scientists have made a very small robot that looks like a fly. It weighs just 65 milligrams, or a little more than the plastic head of a push pin.

    What gives power for the robot to make it {#blank#}6{#/blank#} (fly)? This is a problem. It can only fly when it is connected to a wire that gives power.

    Scientists {#blank#}7{#/blank#} (try) to turn real bugs into robots in other ways these days. US scientists have put computer chips into moths (飞蛾) so people {#blank#}8{#/blank#} (control) them.

But sometimes these robots {#blank#}9{#/blank#} (be) in danger. They can {#blank#}10{#/blank#} (eat) by birds. Other times they can be caught in spiders' webs.
