阅读理解。 At first, Betty and Barney felt comfortable in the alien space station. They were not afraid because the aliens were very friendly. They stood around and looked at them. Some of them pointed at Betty and Barney and spoke to each other in a language they didn't know. After about thirty minutes, the aliens began to feel them and to check them. They were very interested in Betty's and Barney's bodies. Then, some of the aliens cut pieces of hair from Betty's and Barney's heads and took small pieces of skin from their bodies.
