问题 Teratomas are unusual forms of cancer because they are composed of tissues such as tooth and bone not normally found in the organ in which the tumor appears.
选项 A、because they are composed of tissues such as tooth and bone
B、because they are composed of tissues like tooth and bone that are
C、because they are composed of tissues, like tooth and bone, tissues
D、in that their composition, tissues such as tooth and bones, is
E、in that they are composed of tissues such as tooth and bone, tissues
答案 E
解析 B、C中用like进行列举，不符合GMAT中应该用such as举例的要求；B中：that are也属多余；D的表达把句子的主次颠倒，原本属于主要内容are composed of变成了从属部分，而tissue such as tooth and bone这个原本属于次要内容的位于从属地位的过去分词短词却变成了句子的谓语部分，句意发生改变。A、E之间的徘徊在于确认划线部分之后的过去分词短词not normally found是修饰tooth and bone，即A，还是修饰tissue(大的范畴)，即E。由句意分析，本题选E：该过去分词是修饰tissues。一般来说，表某物“区别于其他物体或具有独特性”时，一般用is that，而不用because，E选项正表达了此意(前面是unusual)。
