D 有个地方不爽，就是have to be posted ，感觉就象be able to be done，后者是个必错的表达。

be able/unable to be done. sth having/ having been done肯定错误, 但是没听过说have to be done是不对的呀. 能否举几个ETS的例子???

jnlvo

做过的题目中没有找到相应的said that例子，不过在网上找到一些，如：


Sullivan also said that while increasing enrollment is one factor in the schedule change, it is not the primary factor.


而且感觉日常应用中said that后，在表达某个schedule时，用一般时多于过去式。

我是没找到很好的例子说明have to be done错，不过我在做过的题目中也没找到有这种表达的。我看bryony举的些例子中都没有have to be done，所以我提出这个问题，希望大家找找有无权威的例子含有have to be done，如果有就说明我的推测是错的。

GMAT RC中有很多的have to be done的例子. 我觉得ETS认为这种用法没错

jnlvo

我找了gmat前几个section，没找到。weiyu你能不能举几个例子。最好have to be done的主语是无生命的东西，如schedule。

jnlvo

确实找到了几个have to be done的例子，而且be似乎还可以省。

jnlvo

If, however, physicists could show that the Earth’s gravitational force has decreased with time, expansion would have to be reconsidered and accommodated.fficeffice" />

    

If the “new techniques” mentioned in line 31 were applied in studies of biological classifications other than bacteria, which of the following is most likely?

(A) Some of those classifications will have to be reevaluated.

    

如果选A, 可能到头来还是主客观。以上两个例子来自阅读，从文中感觉，would/will have to be done 是偏客观的，好像是有了个什么条件，sth.不得不怎样。

而本题中said感觉主观成分多些。

对对对Jnlvo.     我每次都将have to 翻译成不得不, 所以感觉这里这个意思很别扭. 但是时态好像又是GMAT中比较有效的判断方式. 所以选择了E. have to是表是客观. 关键就是tianwan兄说must在表达必需时可以和have to换用了.

jnlvo

其实现在，我也不敢完全肯定到底选几，因为没有看到ETS的权威说明。不过，weiyu兄，你的启发和tianwan，bryony兄的博引确实让我受益匪浅。平时自己做一道题那会想那么多，现在却对must和have to有了更进一步的认识，而且对team-work也有了更深的体会。
