Wangdaya: 虚拟条件句主句和从句都必须是虚拟语气。 expect,believe,suspect,dream 等动词用于否定句或者疑问句,其后的宾语从句一般用虚拟语气,用should+动词:He just couldn’t believe that his hometown should have gone through such great changes. is expected to是expect+不定式,和虚拟语气无关,is expected本身也不是虚拟语气。ffice ffice" />
Wangdaya:至于分隔修饰,介词词组,非限定分句,同位语分句,关系分句做后置修饰语都可以被分隔,修饰语本身也可以被分隔。同时,介词词组修饰比关系分句修饰要简洁。
Work has been started on the new system of motorways. 介词词组被分隔
Arrangements have been made to install safety devices on all machines. 非限定分句被分隔
The question sometimes comes to my mind whether it was worth the effort. 同位语分句被分隔
This gave me an opportunity to think out the text of a letter to Vita which she would get the following morning. 关系分句被分隔
comparable facilities to ours= facilities comparable to ours修饰语本身被分隔
ca3ltoys:一般情况下,英语用should do虚拟式时美语用be型虚拟式,即省略should.
Ohayo:they指的是二者合起来。Jnlvo和雪落无声的解释是对的。
这题主要应该考虚拟语气,后面的were to是判断的依据,ETS特意将agreement(单数)提前改成被动,因为如果they做主语,sign可以理解为陈述语气或者是be型虚拟语气。虽然我没有从语法书上直接查到用条件句主句用be型虚拟式的例子,根据虚拟条件句主句和从句都必须是虚拟语气的原则,陈述语气肯定是错的。如果were to改为should, 前面用陈述语气也可以。
大家讨论。毕竟C的句子意思有点古怪。如果不参考语法书,我在考试的时候很可能会选A。ETS可不是好惹的。
