答案详解

1.[A]【解析】在并列从句中，为避免重复，相同的成分可以省略，原句为：“Nebraska has floods in some years, and Nebraska has drought in other years.”。

2.[B]【解析】that引导主语从句。

3.[D]【解析】that引导的宾语从句中主语中心词为collection，所以应使用动词的被动态，且动作发生在将来，用be to表示按计划或正式安排发生的事。本句中，it为形式宾语。

4.[B]【解析】ensure后需接动名词或宾语从句。receive的动作发生在ensure之后，不能用完成时。

5.[A]【解析】all the more为固定搭配，意为“更加”。
