A.interesting B.necessary C.bad D.easy 答案：C 解析：从句“我们花太多时间玩电脑游戏”这一行为应对应消极性质的形容词，bad (不好的)符合逻辑，句意为“我们花太多时间玩电脑游戏是不好的”。 2.(2023江苏常州期中，译林版)Itis一that the little boy can speak three languages. A.surprising B.boring C.difficult D.dangerous 答案：A解析：“小男孩会说三种语言”这一情况具有“令人惊讶的”特征，surprising(令 人惊讶的)与从句内容搭配合理。 重难点三：从句的时态及虚拟语气的运用讲解： 当主句形容词为important,.necessary,strange等表示“重要”“必要”“奇怪”等含义时，从句谓语 动词常用“should+动词原形”，should可以省略，这种情况属于虚拟语气的一种用法，强调建议、 要求、惊讶等语气。若形容词不表示此类含义，从句时态根据实际情况使用相应时态。 例句： ·It is important that we(should)study hard.(important表示“重要的”，从句用“should+动词原 形”，should可省略) ·It is true that he went to Beijing yesterday.(tue表示“真的”，从句陈述过去事实，用一般过去 时) 真题再现： 1.(2024江苏扬州月考，译林版)It is necessary that we hands before meals. 2 8下译林版 【寒假专版】 译林版重难点精讲 A.wash B.washed C.will wash D.are washing 答案：A解析：形容词necessary后的从句需用虚拟语气，谓语动词用“should+动词原形”， should省略，因此用wash: 2.(2023江苏镇江期末，译林版)It is strange that she_late again today..
