【題目】If I _____it with my own eyes ,I wouldn’t have believed it.

A. didn’t see B. weren’t seeing

C. wouldn’t see D. hadn’t seen

【答案】D

【解析】

試題分析：句意：如果不是我親眼看到，我不會相信。根據(jù)后半句wouldn’t have believed可以判斷是對過去的虛擬。所以從句是if+主語+ had+done的形式。故選D。條件句中有if引導時,首先要根據(jù)句意和句子結(jié)構(gòu)判斷是真實條件句還是虛擬條件句,如果符合虛擬的結(jié)構(gòu),就可以根據(jù)句子中的時間和語意判斷應該用哪種虛擬語氣。

In most cases, almost everyone visit a café or friend’s house asks for the WiFi password first. The Internet seems have become one of your basic needs. And 60% of the world’s population still didn’t have Internet access. The situation is even more worse in the least developed countries---only one in 10 people have regular access to the Internet. That’s’ why in the recent survey, many people think of Internet access as a privilege instead of a human right.

However, the UN has made it clearly since 2011 that the Internet, that should be accessible to everyone, is a human right.
