Vocabulary

How does a linguist measure the vocabulary size? I tried to check my vocabulary seize on the web for various vocabulary check.. Depending on some tests, my Japanese vocabulary seize was about 65,000, and as for English, it was from 3,000 to 15,500. (English is a foreign language for me.)
  It was strange that the vocabulary seize wasn't fixed at all in English.
 Possibly, I suppose that I remembered several difficult words, though I missed easy ones or spelling.
 I always miss spelling in English very much. So, my score was so low when there are spelling checks in the test.
 By the way, I've not known these following words till now.

BUFFOON
INFLAMMABLE
SCURRY
SPIRITED

These are 13-14 year old level. (SAT native) 
 Whereas,
I answered correctly
MATRIX
PERSONA
SYSTEMIC
MIRAGE
ADJUNCT
SUPINE
These are high school graduated level (This level is too difficult for me.)

I am a man of brave.

My English skill turned out to be equal to 8th grade of middle school in English-speaking regions. Nevertheless ,in English,I write various themes in this blog. HOW BRAVE I AM !

Jobless Society

Whenever I am studying English, U.S social problems annoy me. I can't stop following social issues in U.S. If I could, I would neglect them. I don't live in America.So I don't like learning English. All I can enjoy learning without worry is a word game for kids education.
 Jobless  or working poor issue under free trade system is common problem among developed countries. I am practicing a small business now, but Whenever I have no client, I am almost jobless. I heard Security guard is a typical low waged in U.S, in fact, I had been practicing it. Generally, A high educated like me, seldom does such a job.
 The most serious problem I foresee, is a high educated jobless. High educated jobless, especially the man who has various engineering knowledge and unmarried, will have anti-society thinking or want to upset establishment. Perhaps , I afraid , unprecedentedly, many high educated will loose or miss such a job that deserve their self-confidence in U.S.for long time.  

Learning language is quite tedeous itself.

Why is a language text so tedeous? I am now reinforceing my English skill. I need still studying English now. So I get several texts or materials for learning English.(from intermediate to advanced).
 " How to speak on the telephone?"" Let's Enjoy campus life.""What does a boss command his subordinates?"" Happy Honeymoon travel?"
                     ......So What?

 Social Themes in texts for English learner are, for Example, Global warming, The importance of equal opportunity, and anyway,these have no actual appealing. and often based on the LEFT political views.
So, The more advanced in English skill, the more the learner tend to the liberal unconsciously. In Japan, people who are good at English often say"Democrats are right".
 Because I have already read so many books and got various knowledge about U.S or UK in my first language too, and Almost themes are already known  and considered for me. I am bored with such a sentence.
 As a matter of fact, I have no chance to use English without writing now. It is difficult for me to keep my motivation for study.What is the best way to master language?
