power failure 表示断电， power shortage 表示电短缺， 蜡烛是断电时用。
districts一般是政治上的区域划分，areas一般是统计计算时用的区域，zones的话应该是指分开的每个独立封闭的区域（封闭的空间），regions这是用来区分天气气候不同的区域。所以说这里regions最适用，因为题目指明了是按照天气来划分区域。
考试没考过是知识有限， 不是材料有限
考察收入来源， 来源是source 。 roof 是屋顶，
and 连接的两个主语， 谓语用复数。
the United States 指的是美国， 其代词用it 。
C 答案 多了个 to . needn't have hurried 才对
应该是 bought 吧， 买表的保修期， 用C.guarantee
anything but unhappy 表示绝不是不高兴， 意思是很高兴。

第九题还是不理解

geographical feature.】 地区

anything but 是根本不， 绝对不的意思

rather than 意思是 而不是
more than unhappy 是非常不高兴的意思
不好意思，打错了，应该是第17题还是不理解，不是19题。
追答17.Having plenty of time,_______.
A.we didn’t need to hurry B.there was no need for us to hurry
C.we needn’t to have hurried D.hurrying was not necessary
句中 Having plenty of time 是分词作状语， 其逻辑主语只能是 we , 我们有足够的时间， 所以排除B 和D ， 另外， need 既可以是情态动词，也可以是行为动词， 情态动词need后应跟动词原形， 其否定式是 needn't do / needn't have done , need 是实意动词 的否定式是 doesn't / didn't need to do ,所以正确答案是 A， C是错答案。
