没想到找了半天,发现大家对这道题目的讨论不是很多。偶来再问.
1,a 和d的区别在哪里? d 为什么不对? that is known 有问题吗?
2,a里面,Mars后面的a planet now known to be 是什么结构?同位语?独立主格?还是状语补充?
3,again venture to Mars 和venture again to Mars,个人觉得都可以的。理解错吗?
请大家指点,谢谢啦。 140. 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. (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
