Q19:

Possible long-term consequences of the “greenhouse effect,” the gradual warming of the Earth’s climate, may include melting the polar ice caps and a rising sea level.

1. may include melting the polar ice caps and a rising sea level

2. may include the melting of polar ice caps and the rising sea level

3. may include polar ice caps that are melting and sea levels that are rising

4. include melting the polar ice caps and sea levels that are rising

5. include melting of the polar ice caps and a rise in sea level

答案E，可我选了B，E的melting应该是现在分词，怎么能跟名次rise并列？B中天和the melting和the rising sea level都是名词，并列用不对吗？

请高人指点！谢谢！！！

b是绝对不能选的，只能在D和E里面选，D的意思是错的，E还能讲究平行，所以只有E了，句首POSSIBLE决定不能选有MAY的，因为重复了，这是考点之一.

1,句首POSSIBLE决定不能选有MAY

2 may include the melting of polar ice caps and the rising sea level中 melting 和 sea level 不并列。

3 include melting of the polar ice caps and a rise in sea level 中melting rise 两个动作性名词并列。
