问题 It may be another fifteen years before spacecraft from Earth again venture to Mars, a planet now known to be cold, dry, and probably lifeless.
选项 A、again venture to Mars, a planet now known to be
B、venture to Mars again, a planet now known for being
C、will venture to Mars again, a planet now known as being
D、venture again to Mars, a planet that is known now to be
E、will again venture to Mars, a planet known now as being
答案 A
解析 本句逗号之后的部分，是对Mars的补充解释，known for being，known as being中的being均为多余，应改为known to do sth．。而D中：that is属多余，选A。
