1. C
翻译:他是否会出席明天的会议还不是那么确定.
解释:从句意not可以看出,从句有“是否”之意,排除D;
it是形式主语,后面的从句才是真正的主语.而作主语从句的“是否”是不能用if,只能用whether的,排除B;
此句型“it's certain that从句”或“it isn't certain whether从句”中的certain不能用sure来代替,排除A.
2. D
翻译:他以一种友好的方式对待他周围的人们,而不管他是否认识他们.
解释:friendly是形容词,而不是副词,所以它不能做状语,修饰动词treat,排除AB;
此题的whether是连词,引导一个后面加or选择的让步状语从句,好比no matter一样,而if是没有此功能的.
再如:Whether it's summer or autumn, farmers are always busy.
不管/无论是夏天还是秋天,农民们总是很忙.
