shuhe

过去完成时
过去发生的两个动作，有明确的时间先后，用一般过去时和过去完成时加以区分

3.    Althoughvarious eighteenth- and nineteenth-century American poets had professed an interest inNative American poetry and had pretended to imitate Native Americanforms in their own works, it was not until almost 1900 that scholars andcritics seriously beganstudying traditional Native American poetry in native languages.
在began studying之前就已经professed and pretended

6.    Inlate 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza wereclosed to visitors for cleaning and repair because moisture exhaled bytourists had raised thehumidity within them to such level that salt from the stone was crystallizing and fungus was growing onthe walls。

Raised发生在wascrystallizing and funguswas growing之前

36.Dressed as a man and using the name RobertShurtleff, Deborah Sampson, the first woman to draw a soldier's pension, joinedthe Continental Army in 1782 at the age of 22, was injured three times, and was discharged in 1783because she had become too ill to serve.
Had become too ill，然后 was discharged

69. Oncethey had seen thereport from the medical examiner, the investigators had no doubt that the body recovered fromthe river was that of the man who had attempted to escape from the stateprison.
一旦已经看到report 就不会dout

76. Retailersreported moderategains in their November sales, as much because their sales a year earlier had been so bad asbecause shoppers were getting a head start on buying their holiday gifts.

123.Less successful after she emigrated to New York than she had been in hernative Germany, photographer Lotte Jacobi nevertheless earned a small group ofdiscerning admires, and her photographs were eventually exhibited inprestigious galleries across the United States.

139.The company announced that its profits declined much less inthe second quarter than analysts had expected and that its business would improve in thesecond half of the year.

1.     In areview of 2,000 studies of human behavior that date back to the 1940s, twoSwiss psychologists declaredthat since most of the studies had failed to control for variables such as social class andfamily size, none could be taken seriously.


这一句比较特殊，had feared之前没有明确的过去发生的动作做参照点，为什么用过去完成时，是因为earlier in the year，表明了是在“过去”之前的时间点
50. Accordingto some analysts, the gain in the stock market reflect growing confidence thatthe economy will avoid the recession that many had feared earlier in the year and instead come in for a"soft landing", followed by a gradual increase in business activity.

再来看这道题，B选项除了and之后缺少主语之外，语法上是没有错误的，但是除了句意强调“primarily”，还有were planters和supplemented是没有必要放在一条时间线上的，因为were表示的是状态，而不是一个动作，supplement发生在什么时候都不影响他们是planters。所以不一定两个动词出现，就一定要区分先后，还有若出现“after”等明确的表先后的词，可都用一般过去时。
19.  TheIroquois were primarily planters, although they supplemented theircultivation of maize, squash, and beans with fishing and hunting

【B 】 and had supplemented
