刚做一套princeton的模拟时遇到的，感觉答案都不对劲。。

In the 1980s junk bonds were regarded             by many investors to be an ingenious way for new companies to raise capital, but in the 1990s it had come to be a symbol of the excessive risks and irresponsible       trading that helped cause the recession.
(下划线怎么都复制不过来。。所以就空格代替啦，请原谅！！）

A. regarded by many investors to be an ingenious way for new companies to raise capital, but in the 1990s it had come to be a symbol of the excessive risks and irresponsible

B. by many investors regarded to be an ingenious way for new companies to raise capital, but in the 1990s it came to symbolize the excessive risk and irresponsible

C. then regarded, by many investors, as being an ingenious way for new companies to raise capital, but in the 1990s they came as a symbol of risking excessively and irresponsibly

D. regarded by many investors as an ingenious way for a new company to raise capital, but in the 1990s they had come to symbolize the excessive risk and irresponsible

E. by many investors regarded as being an ingenious way for new companies to raise capital, but in the 1990s they came to be a symbol of the excessive risk and irresponsible

答案是D, 我原本也想选来着。因为排除了其他代词和regard to be 的错误后就剩DE
但是那个过去完成时实在是太刺眼了所以选了E, 虽然being也扎眼但是时态错的话就绝对不行啊..
所以想问问这里用过去完成时对吗？这不是表示是在过去时之前的状态和句意不符啊。
对完成时真的很头昏。。

谢谢大家啦~~！！！

这就是manhattan没有看仔细的结果了卤煮

仔细回想下manhattan，这就是所谓的用时态来糊弄人最tricky的题目


E选项的being必须是多余的

Also note thatthe later past event does not needto be expressed with a Simple Past tense verb.

You could justuse a date or another time reference.

   Right: By 1945, the United States HAD BEEN at war for several years.

Using thisconstruction, you can even make a trickysentence in which the first clause expresses an early action in Simple Past. Then ,a second clauseexpresses a later action inPast Perfect to indicate continued effect (by a still later past time)

Right: Theband U2 WAS just one of many new groupson the rock music scene in the early 1980’s, but less than ten years later, U2 HAD fully ECLIPSED its early rivals in the pantheon of popular music.

好好再去看看时态的这个章节
