答案是D

Answer 1

1.董事会成员通常认为主要的注意力应该被给到会带来最大利益的项目。attention只能用被动语态，所以答案是“应该被给”
2.air conditioning 是温度调节功能，所以排除AC，gas不能做为特征，low gas mileage应该是每公里低油耗的意思
3.我觉得应该选C...
4.在短语像“冻人得冷，烫人得热，或者让人湿透得潮”中，那些-ing的分词是用来强调，冷，热，潮的程度，所以答案是D
5. 在句子“为了泼出去的牛奶哭泣时没有用的”中，写字的部分是作为？斜体的是哪部分啊？crying over the spilit milk？这句话是主语从句，正常语序应该是：Crying over the spilit milk is no use

Answer 2

第一个 前面general understanding 表示普遍共识 后面应当用 should ……

Answer 3

第一个表示普遍共识 用should就好 第二个根据句意车的特色 然后还有单词（专有名词）用法选D 第三个根据句意和单词形式其实就是找一个副词来修饰take a look这个动词短语，根据句意选A 第四个freezing、burning、soaking本身都是形容词 用来修饰后面的cold、hot、wet（三个也是形容词）就是加强效果所以D 最后一题划线部分？
