大全 170

170.Because the financial review covered only the last few fiscal years, and therefore the investigators were unable to determine the extent to possible earlier overpayments.

(A) and therefore the investigators were unable to determine the extent to possible

(B) so therefore the investigators were not capable of determining the possible extent of

(C) therefore the investigators were unable to determine the possible extent of

(D) the investigators were not capable of determining the possible extent of（E）

(E) the investigators were unable to determine the extent of possible

答案是E。我选c

问题1.therefore的用法应该正确，对吗？

2.我觉得the possible extent of earlier overpayments 早期超资可能的范围，比

the extent of possible earlier overpayments可能的早期超资的范围，好。还是这样就改变了原句的意思了？我经常会犹豫在改变句子意思和表述正确上犹豫，请朋友们给予一些指引？

谢谢！

1－therefore在此处错，because从句后的主句不需要加入so/thus/therefore等词，原因是：累赘；

2－形容词和副词的位置不能轻易改动，因为其修饰的对象是被限定的，改动的话就意味着句意有所改变。对于类似问题，遵循两步：1－尽量保持原意；2－如果保持原意的选项有致命错误，再考虑其他修饰词位置改变但却能表达够接近原意的选项。
