198. Although Napoleon’s army entered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days.

(A) they had in their previous campaigns

(B) their previous campaigns had had

(C) they had for any previous campaign

(D) in their previous campaigns（E）

(E) for any previous campaign

If than is followed by a clause referring to army, the subject of that clause must be singular (it). Furthermore, the verb of that clause will need to be in the past perfect form (had had) because it refers to a time before the simple past of entered. Finally, the preposition for is more precise than in because supplies are gathered for an upcoming campaign. Choices A and C incorrectly use the plural they and the simple past had. Moreover, A uses the less precise in. Choices D and E wisely dispense with the full clause and use a simple prepositional phrase. D, however, uses the imprecise in and the plural their. Only E, the best choice, avoids all the errors mentioned above.

最近狂啃og,越看问题越多.请教此题的比较问什么than后不补出those指代supplies呢？印象中好像除了比较的是主语外，其他都应该加代词的？此题这样的结构没有歧义么？

1，those和that只能替代，而且只在that of和those of时用。

2，Although Napoleon’s army entered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days. 这个it决定了A，B，C，D都是错的。

3，than和as在比较时，都有代词的性质，后面可以直接加介词短语。

2，Although Napoleon’s army entered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days. 这个it决定了A，B，C，D都是错的。偶明白，但是og地解释其实也是在强调是supplies for previous campaigns,那为什么不加上supplies或those呢？

可以省略吧。

3，than和as在比较时，都有代词的性质，后面可以直接加介词短语。——请教这是什么意思？

不好意思，才看到。

Although Napoleon’s army entered Russia with far more supplies than （it had had ）for any previous campaign， it had provisions for only twenty-four days.

than有关系代词的性质，在比较分句中作宾语。本题的答案中省略了从句的主谓语。

那什么情况下直接加介词短语，什么情况下要补出从句的主谓语？

than后面不是需要平行吗？我觉得应该补成：

Although Napoleon’s army entered Russia with far more supplies than （it had entered Russia with ）for any previous campaign， it had provisions for only twenty-four days.

不知道是不是？ 但是OG里没有提到另外几个答案用 it had/ it had had的错误。 望指教。

是不是应该改成：

Although Napoleon’s army entered Russia with far more supplies than （it had had suppies ）for any previous campaign， it had provisions for only twenty-four days.

总是不明白than在比较句型中什么时候是代词、什么时候只是比较句型中的连词？

我的看法请大家讨论，

我觉得全部补全应该是这样的

Although Napoleon’s army entered Russia with far more supplies than (supplies that) it had had for any previous campaign， it had provisions for only twenty-four days.

由于than，as 在比较结构中可以引导定语从句，括号中的部分可以省略，这与ＥＴＳ的解释一致：“If than is followed by a clause referring to army, the subject of that clause must be singular (it).

同样这句话这样表达也没错，Although Napoleon’s army entered Russia with far more supplies than (supplies） for any previous campaign， it had provisions for only twenty-four days.

介词短语修饰名词。由于是名词与名词的比较supplies 可以省略。
