以下是引用sihua在2004-9-14 18:06:00的发言：

85. The various peoples who developed

   North America have made it a world

   leader economic .

                               D

    为什么不是c

C怎么错了？请注意这里的主语是peoples；make的用法，make sth1 sth2；D选项，这里的sth2应该是“世界经济的主领者”，economic是形容词，修饰名次leader应该前置，D项应该改成economic leader

89. Prehistoric villagers tended to work harder, suffer

   from more diseases, and eat the poorer diet than

   nomadic hunters did.

                                 D

     请问怎么改

去掉the就可以了

93. Copper was the first metal used by

   humans and is second only to iron

   into its utility through the ages.

                                 C

     请问怎么改

into表示一个动作的过程；改成in，表示在什么方面

96. Cyclamates were introduced in the early 1950's

   as alternative sweeteners for use by individuals

   who needed reducing their sugar intake for

   medical reasons.

                               D

     请问怎么改

need在这里用过去式显然是一个实义动词，【need to do】固定词组，改成to reduce

98. The Hopi, descendants of the prehistoric Anasazi

   people, are a Pueblo people who of the southwestern

   United States.

                               D

      Why not c   请问怎么改

这里people指一个民族，而【who+不完整句子】构成从句，显然不适合这里，改成people of
