Q40:
Since February, the Federal Reserve has raised its short-term interest rate target five times, and because of the economy’s continued strength, analysts have been predicting for weeks that the target will be raised again in November.
- because of the economy’s continued strength, analysts have been predicting for weeks that the target will
- with the economy’s strength continuing, analysts predicted for weeks that the target
- because the economy continues strong, analysts predicted for weeks that the target would
- due to the economy’s continued strength, analysts have been predicting for weeks that the target
- due to the fact of the economy’s continued strength, analysts predicted for weeks that the target will
记得听语法老师讲过完成进行时在gmat中很少是正确的，因为它表达的意思很模糊，是完成了，还是没完成？当然我想只并不能作为排除a的理由，但我想a中的continued strength是不是不好，continue 是表一个持续的动作，根据原文逻辑，显然现在还在增长，是不是用continuing 好一点？
我原来也选c, 但没注意到because 条件句中用的是continues. 条件从句用一般现在时，主句用过去时，这好像是gmat中的大忌呀。
另外这一句话居然出现了三种时态？太狠了吧？
所以关于时态的问题还请nn们多指教。 |
