Answer 1

1. A
翻译：你知道是什么阻止他接听我的电话？
解释：考查固定短语区别。
keep sb from doing sth 阻止某人做某事；lead sb to do sth 导致某人做某事；protect sb from sth 保护某人不受...的影响/侵害；没有turn sb to doing sth的短语。

2. A
翻译：警察被调来守卫机场，并检查到达的飞机。
解释：选项用and和keep at the airport并列连接，所以两者都在to之后，所以也用动词原形即inspect.

3. B
翻译：请保持端坐状态，获奖者将会很快被宣布。
解释：remain是一个系动词，所以后面加形容词形成系表结构。
选项中只有B seated可以视为形容词，意思是“就座的”。

Answer 2

1. A
answering是ing形式，前面要接介词；keep him from doing 不让他做某事
2. A
全句补全后是Police were called out to keep at the airport ，and （were called out to）—— the arriving planes. 空白处填动词原形
3. B
remain seated 不要离开座位

Answer 3

1C 后面是answering,所以一定不是to, 只有from, 那么have 要跟kept不是keep, 所以只有protected了
2A 与前面的"keep"时态一致, 即是原型，所以是"inspect"
3B remain后加形容词，Seated是 坐着的

Answer 4

1.A让某人一直做某事2.A and连接两个并列动词3.B保持坐着seat sb因此sb.be seated
