Passage Four

According to the speaker, how does a nerve fibre look

A.Elongated and stringy.

B.Round and compact.

C.Flat and transparent.

D.Flexible and chainlike.

答案

参考答案:A

解析:

[分析]: 隐含事实的找寻和判断。 根据原文These fibres have branched ends可知这些纤维有许多枝权,由此可推测这些纤维是stringy(多纤维的);义根据But one fibre from the nerve cell may stretch as long as three feet可知神经细胞上的一条纤维可以拉长至三英尺长,由此可推断纤维是elongated (可拉长的)。因此A项内容与原文相符,是正确答案。[解题关键] 理解原文中某些词语的替换性表达。
