大全446，again的位置

446.   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（A）

(E) will again venture to Mars, a planet known now as being

觉得again venture to Mars很怪阿；我觉得应该是 venture to Mars again,如果B后半句known for being 改成known to be是不是更好呢？请指教！

不明白，我就是因为a中again的位置排除a的。D怎么就不好了？

楼上解释的，偶看不懂，能不能再细节一些？

again修饰谁呢？修饰venture吗？（这里venture好像做动词）

got it! found a sample from M-W: we may, and again we may not~  but the meaning of again here is"on the other hand",is it same with initial sentence?

jasnoyang

thanks! can you give me some samples? I did search Longman, but fail to find any samples like this

again is an adverb, which can be used before the verb of a sentence or a clause
