[简答题]Time was when the solar system had two watery worlds. 61) Directly next door to the warm, wet, loamy Earth was the warm, wet, loamy Mars, both planets covered with oceans and running with rivers—and both possibly teeming with life.

That is what the prevailing thinking has been. Now, it appears that thinking may be wrong. 62) Recently, NASA released new images from the Mars Global Surveyor spacecraft that suggest water may be flowing up and streaming onto the Martian surface—dramatically increasing the likelihood that at least part of the planet is biologically alive. "If these results prove true," says Ed Weiler, associate administrator of NASA’s Office of Space Science," [they have] profound implications for the possibility of life. "

At that time, Yee was all the way on the other side of the sun and couldn’t hear the wails that rocked Lan through and through. After so long they were together again. Lan was almost afraid to look at Yee, but
