正确答案： C:None of the shipments sent by Comcorp to Truax Construction last week was specially ordered.

答案： C

题干分析：

上周，没有建筑用品的货物是在周五派发的。周四发出了五个特殊定制的货物，

每一个货物装的都是建筑用品。上周寄送了四个货物到 Truax，没有一个是建筑

用品。

选项分析：

A 选项：所有上周的 Comcrop 的建筑用品货物都是特殊定制的。文段中说周四发

出的那五个货物是特殊定制的，并没有说所有上周的货物都是特殊定制的。

B 选项：没有任何一个 Comcrop 在周五的货物是给 Truax 的。周五 Comcorp 没有

发过含建筑用品的货物，又没有说周五没有寄送到 Truax 的其他货物（比如洗漱

用品）。

C 选项：对。 Truax 收到的来自 Comcorp 的货物，没有一个是特殊定制的。五个

特殊定制的货物都是在周四发出的，且都是建筑用品。但是，上周 Truax 没有收

到过任何建筑用品，说明这些特殊定制的货物都不是发给 Truax 的。

D 选项： Comcrop 在周四发出的货物，没有一个是发往 Truax 的。文中只说了

Comcrop 在周四发出了五个特殊定制的货物，且它们都是建筑用品，又没有说

Comcrop 周四只发了这五个定制货物，也许还发了其他类目的货物出去。所以我

们不能确定周四是否有发给 Truax 的货物。（也许上周寄给 Truax 的货物正好是周

四寄的呢）

E 选项：所有 Comcrop 的建筑用品货物都是周四发出的。文中只说周四发出了建

筑用品货物，周五没有发建材的货物，又没有说周一周二周三没有发。
