1．The local peasants gave the soldiers clothes and food without which they ________ of cold and hunger. (江西)
A．would die B．will die
C．would be dead D．would have died
答案：D
解析：
当地农民给那些士兵衣服和食物，没有这些东西，他们就会饥寒而死。本题考查虚拟语气中的含蓄条件句用法。形式上看本句是一个含有定语从句的复合句，主句为：The local peasants gave the soldiers clothes and food。定语从句的先行词是clothes and food，将先行词代入定语从句后为：They ________ of cold and hunger without the clothes and food.由主句内容可知说话者介绍的是过去的事情，因此设空处应该是与过去事实相反的虚拟语气，谓语动词应该是would/should/could/might+have+过去分词，故本题答案为D项。
2．Being a parent is not always easy, and being the parent of a child with special needs often carries with _______ extra stress. (北京)
A．it B．them
C．one D．him
答案：A
解析：
作家长不容易，作一个孩子有特殊需求的家长更具有压力。此题考查代词。it指代前面的“being the parent of a child with special needs”。
3．Over the past decades, sea ice ________ in the Arctic as a result of global warming. (浙江)
A．had decreased B．decreased
C．has been decreasing D．is decreasing
答案：C
解析：
在过去几十年里，由于全球变暖，北极的海冰一直在减少。由时间状语Over the past decades可知，主句只能用现在完成时，故选C。
