标题: og 208 & 210 [打印本页] 作者: iamf 时间: 2002-12-2 22:56 标题: og 208 & 210
Teratomas are unusual forms of cancer [U]in that they are composed of tissues such as tooth and bone, tissues[/U] not normally found in the organ in which the tumor appears.
上面的句子，连续用了两个tissue，如果改成下面的样子会不会对呢？
Teratomas are unusual forms of cancer [U]in that composed of tissues such as tooth and bone which are not normally found in the organ in which the tumor appears.
210.Scientists have recently discovered what could be the largest and oldest living organism on Earch,a giant fungus that is an interwoen filigreee of mushrooms and rootlike tenteacles spawned by a single fertilized spre some 10k years ago and [U]extending [/U]for more than 30 acres in the soil of Michigan forest.
源解释说extending和spawned很好的并列！不懂，不知道怎么样理解？
请大虾们指教～作者: princess 时间: 2002-12-2 23:36
1.你的改法有问题
因为in that 引导的原因状语从句中缺少了主语
索性把in that去掉到也对了
Teratomas are unusual forms of cancer [U]in that composed of tissues such as tooth and bone that (which) are not normally found in the organ in which the tumor appears.
不好意思，改动的句子少了两个单词：Teratomas are unusual forms of cancer in that they are composed of tissues such as tooth and bone which are not normally found in the organ in which the tumor appears.
spawned by a single fertilized spre some 10k years ago and extending for more than 30 acres in the soil of Michigan forest.
两个动词表达的时间意思不一样，前一个有10k years ago ，表过去
而后一个表示一直到现在也是这样，所以用现在分词。如果改成过去分词的话，就表示过去是而现在已经不是extend for more than 30 acres in the soil of Michigan forest.作者: tongxun 时间: 2002-12-4 19:26
