73. 

Radiocarbon dating of fossils taken from caves on islands along southeastern Alaska's coast suggest that at least a portion of the area was remaining ice-free during the last ice age.

(A) suggest that at least a portion of the area was remaining

(B) suggest at least a portion of the area remaining

(C) suggests that a least a portion of the area remained

(D) suggests at least a portion of the area that had remained

(E) suggests at least a portion of the area to have remained

答案是C

可是SUGGEST + THAT + V (原型)吗

我因为这个..一下就从C D E里面把C删了....选了E......虽然HAVE REMAINED 这个时态不是很多...但是 我也见过......

第一，看PREP解释，

第二，GOOGLE

第三，查语法书。

偶可以很容易地告诉你这题的答案，但是偶想这个题目你是可能解决的，对不。

试着靠自已做一下。

如果这些都做了，你还找不到，偶帮你解决。但是你得告诉偶你做的这些都找到了些什么，学到了什么。

MM，只有这样，SC才能真正过关，要的是一个提高的过程，而不是某一点答案。

汗，貌似偶还不如打一行字，解决了这个问题还比较快。
