OG151中对if时态用法的疑惑

以下是引用xealot在2004-12-2 19:40:00的发言：

But I don't think you need to stick on the paradigms... Just keep two basic principles in mind:

1. Keep the meanings consistent;

2. Never use any future tense in subordinate clauses.

I see what you mean about that, but the first one, in fact, is difficult to control .

If you can offer an example to describe how to distinguish between if x happens, y will happen and if x happens, y will happen , I will appreciate you a lot.

i want to know this too .

by the way ,i think the explanation of the og146 is contradictory to that of the og151.

the og146's the explanation  said : Choice B incorrectly uses a future-tense verb (will be) in the if clause; the if clause must use the present tense if it is preceded, as here, by a result clause that uses a future-tense verb (e.g., will find).  

I am confused now ,

OG的意思應該是說 if s+V (這裡要用現在式), S+V (這裡才能用will)

if it is preceded 表順序在前的句子吧

我倒是觉得没有必要纠结于虚拟语气. OG中虚拟语气用得极少, 除了那种省略should的

Why does not the sentence use the subjunctive mood of the verb will be?

If Dr．Wade is right，any apparent connection
                between eating highly processed foods and excelling at sports
                is purely coincidental．
