请问下偏标准差(lower partial standard deviation)的定义和计算方法?
和计算受益标准差相似，讲标准差中的样本均值换成无风险收益率。可以更有效衡量风险
lower和bottom的区别
1 lower 通常是形容词，搭配是 the lower part (of sth. ) 。2 bottom是名词，解释为“the lower part”。3 在这里， the bottom line 中，bottom是名词做定语/形容词。
These wild flowers are so special that I would do ____I can to save them. A．whatever B．that.
A 考查名词性的引导词。题意是：这些野花太特别了，我想尽我所能拯救它们。句中do后是一个宾语从句，I can 后承前省略了谓语动词do, to save them 是目的状语。可以看出宾语从句I can do 不完整，缺少宾语成分，所以引导词要用关系代词what 或whatever.人们常把 do what/whatever sb can to do sth 当承一个句式，意为“尽力去做某事”。故答案为A.

落落用的是佳能单反,主要还是有P过的成分.

“on”能与“price”搭配吗？ 比如：in a lower price 还是 on a lower price 呢？
in the lower price
show me flower这句话对吗？
这句话不对，应该是show me flowers或者show flowers to me。
I think that it is a flower这句话为什么要加is？
因为that后应该是一句话，如果没有is，后面句子就缺少谓语，就不成宾语从句了。当然你也可以删掉that，这时可不用is。I think it a flower. 这时it是宾语，a flower是宾语补足语。
