答案
1.【答案】C。解析：考查强调句。强调句固定句式it+is/was+强调部分+that，此题中拿掉it+was+that结构，成分完整，故为强调句;且前后两个句子独立完整，需要用时间状从连接词not until来联系，not…until的强调句型结构为：It was not until….that+句子。故选C。
2.【答案】A。解析：考查强调句。not…until的强调句型结构为：It was not until…that+句子。故选A。
3.【答案】A。解析：考查强调句。判断强调句和时间状语从句的区别就是去掉it is/was...that观察原句子是否完整，若完整则为强调句，故本题为强调句，强调时间状语during the Second World War。故选A。
4.【答案】D。解析：考查强调句。强调句固定句式it+is/was+强调部分+that，此题中拿掉it+was+that结构，成分完整，故为强调句,强调句一般疑问句的结构为：Was/Is it+被强调部分+that+剩余部分?故选D。
5.【答案】B。解析：考查强调句。强调句固定句式it+is/was+强调部分+that，此题中拿掉it+was+that结构，成分完整，故为强调句,被强调成分为the ability to do the job。故选B。
