試題分析：句意：要是沒有電，人類的生活會和今天有很大的差異。本題重在理解without虛擬語氣的用法：
1. 與現(xiàn)在事實相反：Without air, man couldn't exist on the earth.沒有空氣的話，人類將不能在地球上生存。
謂語動詞：would/could/might (not) do sth.
2. 與過去事實相反：Without your help, I would have failed the exam last week.沒有你幫助的話，我上周考試可能就通不過了。
謂語動詞：would/could/might (not) have done sth.
3. 與將來事實相反：Without your ticket, I wouldn't be able to go to the concert tomorrow.要是沒有你的票的話，我明天就不能去聽音樂會了。
謂語動詞：would/could/might (not) do sth.
點評：虛擬語氣是高考每年的必考點，用法較多，平時學習應積累鞏固。
