1.今天先跟大家講下交叉使用will,be going to,will have to三種表達法。
首先講一下will have to是have to 的將來式。
I'll have to...=It will be necessary for me to...
i.e.It will be necessary for them to pass a special test.=They will have to pass a special test.
2.won't have to是指“將不必”，“將沒有必要”，是will have to的否定式，如一般說“不必”，則是另外一種形式。請看，下面三句意思一樣：
You don't have to pass the special test.
You needn't pass the special test.
You haven't got to pass the special test.
3.will have to這一表達法，不能只是解釋為“將來不得不”。
have to
had to

don't have to
不必 didn't have to

或：haven't' got to

will have to
還得
would have to

won't have to
將不必
wouldn't have to

4.shall have to大有被will have to代用之勢，這在現代英語中第一人稱不用shall,是不足為怪的事。
例：We will have to help him as much as we can.
我們還得盡可能幫他一把
5.另外還有較深層次的表達。
1)We might have had to do this.
我們說不定還有必要做這件事呢。
2)These last two days I have had to take a rest.
最近兩天，我確實有必要休息一下。
3)We might have to cancel his plan.
我們也許有必要取消他的計劃。

==============*譯文參考*================
1]公共場所汽車司機決定在下周進行罷工。罷工定于星期二開始。誰也不知道罷工會持續多久。司機們聲言罷工要繼續下去，直到達成關于工資和勞動條件的總協議為止。 2]大多數人認為罷工將至少持續一個星期。許多擁有小汽車的人將為一路去上班的人提供“免費乘車”。這將在種程度上減輕對火車的壓力。與此同時，一些大學生已志愿提出在罷工期間駕駛公共汽車。
3]所有這些年青人都是駕駛能手，但是在駕駛不管哪一輛公共汽車之前，他們還得通過一項專門測試。學生們將在兩天之后參加測試。即使如此，人們還是感到上有困難。只有一兩個表示反對，認為大學生會把車子開得太快的！
