看到很多人对due to和because of的区别都不太清楚，做题的时候不能根据这两个词本身排除，还要找别的因素。其实这两个词是有很大区别的，我是看到了一个鬼佬的解释才彻底明白：
Due to means"cause by". It shoud only be used if it can be substitued with "caused by".
It doed not mean the same thing as "because of ",
Incorrect: The game was postponed due to rain.
Correct: The game was postponed because of rain.
Correct: The game's postponement was due to rain.
以后再遇到due to只要把它换成我们熟悉的caused by就清楚多了。
举例：GWD7-40
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
DE显然无法换成caused by，所以直接排除。当然这两个选项还有其他问题，但是用due to来排除是最快
