Answer 1

1. 选C
come true 实现 take off 脱下，起飞 show up 出现
pay off 取得成功，有收获
根据句意：他多年作为探索者的训练终于有了回报。
2. A the moment 引导时间状语从句= as soos as 一...就...
翻译：他一开口，我就知道他不是北京的。
3.选C 强调句
it is / not until + 被强调部分+that
翻译：他回来时还不到八点

Answer 2

C A D
1.pay off在此处为见成效，得到回报的意思。
2.The moment ....是 一....就....的意思
3.not ……until，是直到……才的意思。

Answer 3

1.C pay off 译为 有所回报
2.A the moment = as soon as
3.B 回答译为：是的，他在回到家的时候还没到八点。

Answer 4

1.C pay off,意为：得到回报，其他意思不符语境
2.A The moment有“一……就”的意思，另，虽然Immediately 也有“一……就”的意思，但， speak无被动用法
3. B 固定搭配 It is/was+时间点+when ， eight o'clock 为时间点
