     One day a person met Socrates and said, “ Do you know what I just heard about your friend?”

"Hold on a minute ,” Socrates replied. “Before telling me anything I'd like you to  pass  the  Filter

(过滤) Test.” “Filter Test?” “Yes.” Socrates continued. “Before you talk to me about my friend, it

might be a good idea to filter what you're going to say. That's why I call it the Filter Test. The first filter

is Truth (事实). Have you made sure that what you are about to tell me is true?” “No, in fact I just

heard about it and...” “ All right,” said Socrates. “So you don't know whether it's true or not. Now let's

try the second filter, the filter of Goodness (好处). Is what you are about to tell me about my friend

something good?” “ No, quite the opposite...” “So," Socrates continued, “you want to tell me something

bad about him, but you're not certain if it's true. Now there's one filter left: the filter of Usefulness

(有用). Will what you want to tell me about my friend be useful to me?” “No, not really. ” “Well,” said

Socrates, “if what you want to tell me is neither true nor good nor even useful, why will you tell it to

me?”

       We can always join in loose talks(闲话). But when it comes to our friends, it's not worth it. Never

talk behindthe back about our near and dear friends.

向盛有硫酸铜水溶液的试管里滴加氨水，首先形成难溶物；继续滴加氨水，难溶物溶解，得到深蓝色的透明溶液。下列对此现象说法正确的是

B．沉淀溶解后，将生成深蓝色的配合离子[Cu（NH₃）₄] ²⁺
