问题1
答案：A
思路：
英语分数，基数词表分子，序数词表分母。当分子是一时，分母用单数形式，当分子大于一时，分母要用序数词复数形式。排除BC。
“分数/百分数+of短语”作主语，这时要以of短语中的名词的数而定谓语动词的数。 it 单数含义，故谓语动词用单数，选A 排除 D。
问题2
三者均表：对别人致谢时的回答, "荣幸"。但是语境、语气不同。
My pleasure ！是正式说法，“荣幸之至”。大致是“It has been my pleasure to help you．”的省略。强调情绪,礼貌虔诚客气.
with pleasure 用于帮助行为发生之前（只是答应了，事儿还没办哪）别人致谢时的回答,大致相同于All right, No problem. I’d like to。。。意为“我会怀着荣幸之心去做”,
It's my pleasure用于帮助行为之后，别人致谢时的回答,语气比You are welcome.更重，“能帮助您我很荣幸”。
问题3
句意：——雾霾天气将持续------？——我不知道。没有结束的迹象。
根据句意，三个都不合适。一般用HOW LONG （多久）对应 last （持续）。
题目有问题。也许有个D: how long,
