请问一下
tpo26听力的conversation 2第22题
D选项
The student should explain how bioluminescence benefits
vairous species of jellyfish differently 怎么翻译?
原文 proffesor 说:
"so you may want to look at a particular type of jellyfish
or several types that benefit from bioluminescence in the same way"
这不能解释为D选项吗？
还有
tpo26 lecture 3 第２３题
答案是(A)The orbits of comets
根据原文 professor 一开始说：
"Let’s continue our discussion now by talking about orbits,
especially those of the so-called periodic-orbit comets".
可以看出答案
但他整篇不是都在讲哈雷彗星的特性吗?
为什么Ｂ选项不行?
(B)"Unique characteristics of a famous comet."
请大家帮我解答 谢谢~
