为什么这两道题PREP的解释认为101题一个可以把what it claims中的it claims认为是插入语，61题却说what it appears is 中what 与it多个主语，appear与is多个谓语，从而排除了A选项呢？
101. (29777-!-item-!-188;#058&004380)
The electronics company has unveiled what it claims to be the world's smallest network digital
camcorder, the length of which is that of a handheld computer, and it weighs less than 11 ounces.
(A) to be the world's smallest network digital camcorder, the length of which is that of a handheld
(B) to be the smallest network digital camcorder in the world, which is as long as a handheld
(C) is the smallest network digital camcorder in the world, which is as long as a handheld computer,
(D) is the world's smallest network digital camcorder, which is as long as a handheld computer and
(E) is the world's smallest network digital camcorder, the length of which is that of a handheld
A. the length of the camcorder (which指代) is the length (that指代) of the a handheld computer，
逻辑不合理。如句子结构部分的分析，is as long as and weighs同修饰camcorder，应同时被which
所引导，在which从句内部。A选项用it而非which指代，导致指代不清，并且使得and it weighs
部分脱离从句笼罩，这样产生了and it weighs属于第一层次，与the company has unveiled并列
的歧义，且在这种情况下，it优先指代company
B. 由于in the world属于核心词camcorder的修饰成分，因此which可以跳跃指代camcorder，
weighing现在分词做伴随状语修饰前句which (camcorder) is as long as…是可以接受的用法。
至于如何排除B选项，请参考D选项和本题补充说明部分的分析
D.正确，Which紧跟在其先行词之后，紧密修饰先行词camcorder；which (camcorder) is … and
E. the length of A is the length of B，错误同A；weighing的逻辑主语为the length of camcorder，
[1] It claims为插入成分，这一现象大多数考生在此处为第一次遇到，因此很多考生会认为claim的正
确搭配为claim to do something，因而排除BCD选项。实际上is和to be在选项中都是正确的表达：
若为is，可理解为it claims是插入成分；若为to be，则可理解成what it claims to be…这一大家都
很熟悉的表达。此题难度确实比较高，这个考点在此题中起到了不小的迷惑考生的作用。但是，
通过以上各选项的分析不难看出，即使不考虑is和to be的区别，通过其他考点，我们也可以排除
掉ACE。在实际考试中，如果考生遇到不熟悉的考点，尽量不要依据这一单一考点作判断，应比
61. (27648-!-item-!-188;#058&003611)
Researchers in Germany have unearthed 400,000-year-old wooden spears from what it appears
was an ancient lakeshore hunting ground as stunning evidence of human ancestors who
systematically hunted big game much earlier than believed.
(A) it appears was an ancient lakeshore hunting ground as stunning evidence of human ancestors
(B) it appears had been an ancient lakeshore hunting ground and is stunning evidence that human
(C) it appears to have been an ancient lakeshore hunting ground and is stunning evidence that
(D) appears to be an ancient lakeshore hunting ground, stunning evidence that human ancestors
(E) appears that it is an ancient lakeshore hunting ground, stunning evidence of human ancestors
A. What从句中出现what和it两个主语，以及appears和was两个谓语，句子结构错误
B. What从句中出现what和it两个主语，以及appears和had been两个谓语，句子结构错误；had been
C. What从句中出现what和it两个主语，句子结构错误；stunning evidence的主语也不清晰；have
D.正确，stunning evidence作为同位语，概括性同位语在句尾对句子进行进一步拓展。
E. What appears that it is…罗嗦笨拙；stunning evidence of human ancestors who…结构中，who
从句为附属结构，核心部分仅为evidence of human ancestors，人类祖先的证据，而人类祖先怎
么样了，证据证明了人类祖先的什么事情这些关键信息，在句子当中都被掩埋了。这种表达方式
谢谢大家了哦
