1.【答案】B

【解析】Under no circumstances“绝不”，否定短语位于句首，其后句子半倒装。“我们绝不会取消派对”，Under no circumstances中已经包含了“不”的含义，故选B。

2.【答案】D

【解析】非限制性定语从句中，as we had expected“正如我们所料”为固定搭配，故选D。

3.【答案】C

【解析】be likely to do；alike意为“像”，只能作表语，如Great minds think alike.(英雄所见略同）,similar “相似的”，equivalent意为“等价的”，根据句意选C。

4.【答案】B

【解析】在it is desirable/advisable/important/necessary that...结构中，that引导的主语从句的谓语动词要使用“should. +动词原形”形式。

5.【答案】A

【解析】动词increase后使用by表示“增加了”，使用to表示"增加到"。因此本题答案为by。句意为：与去年相比，我们今年的夏季粮食产量增加了10%。
