From looking on nckiu I can't find the obvious difference between these two 'to knows' - is there one?

MM.x

My wife insists that my 4-year old only speaks Mandarin with her ("妈妈听不懂.  说中国话！"). Recently, he tries to use German wherever he can.

But often he just cannot comply, because he lacks his core vocab: "Mama, what is Protoceratops in Chinese?"

I had to help out here. Thanks to Wikipedia I could answer my son's (and in turn my wife's) most pressing questions:

Protoceratops: 原角龙

Triceratops: 三角龙

Stegosaur: 剑龙

Ankylosaurus: 甲龙

Tyrannosaurus Rex: 霸王龙

Pterodactylus: 翼手龙

Diplodocus: 梁龙

These are the ones my son wanted to know. I guess he will ask more later (probably all the Chinese ones like the Huangfengosaurus - he will be in Beijing soon).

We definately need a lesson on Dinosaurs.

Hello CP,

            I would like to make a suggestion or two for the vocab manager.  

1) When you add/or remove a label to a word. The list refreshes and takes you back to page one. It would be nice if it left you on the page you were on. 

2) In the "Filtered Lists" section, it would be nice to be able to filter by "No Label"...That way if I remove a label from a filtered list, I do not have to then go through every page of my "All vocab" list to find it and re-allocate it.....Now i'm starting to get more words learnt (thanks to you guys! ;)) it can be a real pain to re-organise! 

Well thats just my 2 pence worth!  

Cheers

I'm having trouble getting my arms around the concept of expressing, "I am thinking...", "I believe...", and "In my opinion...", etc. Is there a difference between "想 xiǎng ", "认为 rèn wéi ", and "认为 rèn wéi ". Also, what would be the best way to express, "In my opinion..."

Thanks.
