時制で軆??ら繧?しいも縺?

■条件を表す副鐔??節は現在形（名詞句は違う）---------------------------
I will start when he comes.　　　　　SV
I don't know when he will come.　　 SVO

■ago縺?before-------------------------------------------------
//agoは現在を起点にし、驕?去で使う
That was happened ten minutes ago.

//beforeは驕?去か未来を起点にし、驕?去完了か未来で使う
When I came back to the office, everyone had left ten minutes before.

■Nowの表軆??-------------------------------------------------
//nowは現在、進鐔??形、現在藹??了
He has finished writing a letter now.

//these days,nowadaysは現在形
They are indifferent to politics these days.

//recentlyは現在藹??了か驕?去蠖?
He has been busy recently.

//just nowは驕?去を暗遉?
He finished writing a letter just now.

//right nowは現在、進鐔??蠖?
I'm doing this right now!

■時制の臀??閾?-------------------------------------------------
どの時点の臀??を言っているのかが決まるので注諢?が必要
聞いてて分かるようになっていると思繧?れ、発鐔??中との觸??較で時制を決めればよい？

//主は現在、従は驕?去
I think it was good.（思ったとき、驕?去のそれがよかった）　
Do you know it was him? / I know it was him.

//主は驕?去、従も驕?去（時制の臀??致・??
I thought it was good.（思ったときとそれが良かったときが同じ時間） 
Did you know it was him? / I knew it was him.

//主が驕?去、従が現蝨?
x)Did you know it is him? / I knew it is him.（これは普通ありえない）

==============================
しかし時制の臀??致を藹??けない文も結構ある、時制の臀??致では表現できないから
==============================
一致を藹??けさせようがない場合は臀??致させな縺?ても良い
（文法を考えるより感覚の方が正しいことも多い）

I thought it is good.（現在もGoodならOK）

これ縺?OK、文法は觸??則であり表現はその枠を超える
Did you know Taro is a student?←これは太驛?がまだ生徒だ縺?OK
Did you know Taro was a student?←これは太驛?が現在生徒でないため時制の臀??致が発生

###時制の臀??致を藹??けない法則###
１）現在の状態・軆??性・職業などを表す(今も)
He told her yesterday that Taro is a college student.
I heard there is a party tonight.
U.S. Secretary said he believed the North Koreans already have some nuclear weapons.

２）不変の真理や社臀??通念をあら繧?す
I learned the earth moves around the sun.

３）歴史臀??の臀??実は常に驕?去蠖?
Everyone knew that the World War 2 ended in 1945.

４）仮藹??法内の動詞
She wished she were a doctor to save her child.

５）条件の副鐔??節
I will start if he comes
==============================

//驕?去の未譚? would
I thought it would be good.（ならあり得る？現在時点で驕?去の推量？）
I thought its gonna be good.（こっち縺?OKでしょう） 
Did you know it is him?（これは饅??目・?? →　Did you know it would be him? or Did you know its gonna be him?
I knew it is him.（これは饅??目・??　→ I knew it would be him. or I knew its gonna be him.


■使いこなしたい-------------------------------------------------
(現在形、現在進鐔??形、未来形、驕?去形は簡単なので省略できる)
●完了形・??現在を含めての軆??邱?
  have been doing縺?have doneの違い
   have been doingは強調・??期間の長さor is doingが驕?去から今に軆??いていることを強調
笳?驕?去完了＝驕?去と觸??べて古い場合につかう大驕?去(Parallelism：事前に大驕?去があって驕?去があることを意識）
  The concert had already started when we got to the theater.
  I lost my pen which I had bought.
●説譏?は全て現在形？
（現在形より未来の、現在形、進鐔??形、未来形しか使えないから2~3ステップしか説譏?できない）
  例文）
    申込み用軆??を書きAへ送信した後、Aは承鐔??を上司に藹??ります。
    その藹??Aからメールが来ますので部門長に許可を藹??ります。
    その藹??権限が付荳?されます
    First of all we have to fill an application form out and send it to A.
    And then A asks the superviser for its approval.
    And then we gets an email from A then we gets the approval from a director.
    Finally we get the previledge for it.
   /// 前置鐔??等でリセットすれば未来形等の現在形以藹??を使っていても現在形に戻れる？
   A sends a request. B will check it. After checking C takes it.

  may:50% > might:30% かも知れない、mayはより確度の饅??い許可の「してもよい」という諢?味もある
