(C which pioneered in treating skull fractures (D he was a pioneer in the treatment of skull fractures
分析:空格后面是and, 空格处缺少和developed、supervised平行的谓语动词,因此选择(B。
四、宾语从句结构
宾语从句的引导词在前面的主从复合句中已经提到。这里指出的是填空题中关于宾语从句考的最多的两个结构:state(陈述,表明+that indicate(指明,表明+that
例1:The quantum theory states ___, such as light, is given off and absorbed in tiny definite units called quanta or photons.
(A energy that (B that it is energy (C it is energy (D that energy
分析:空格前的谓语动词states一般接关系连词that引导的宾语从句,故首先排除C。空格后已有谓语动词,空格不应再出现谓语动词,因此(D正确。
例2:Studies of the gravity field of the Earth indicate___yield when unusual weight is placed on them.
(A although its crust and mantle (B its crust and mantle to (C that its crust and mantle (D for its crust and mantle to
分析:空格处显然缺谓语动词indicate的宾语。(A和(D不能作宾语,可首先排除。(B使句子结构混乱、语义不清,因此选择(D,构成宾语从句。

例1:In the United States, a primary election is a method ___voters select the nominees for public office.
(A that (Bby which (Cis that (Dby those
分析:空格前后都是句子,因此缺从句引导词或连接词,首先排除C和D。A能够引导从句,但是根据题意,修饰method是不通的。B是介词+which, 引导定
语从句,(大选是一种方法,根据这个方法,选民怎么….,因此(B正确。
例2: Croquet is a popular lawn game ------ players hit wooden balls through wire arches called wickers.
(A when (B which (C is when (D in which
分析:空格前后都是完整的句子,空格处缺定语从句引导词,由此首先排除(A和(C。但是到底是选择B还是D,则看从句,从句是完整的句子,那么一定
选择(D, 关系代词which 前应该有介词。
六、in that结构
在表示“原因”概念的引导词中,because of +名词,consequently
是副词而“in that”是原因状语的引导词。
例1:Mercury differs from other industrial metals ___ it i
