試題分析：句意：要是沒有電，人類的生活會(huì)和今天有很大的差異。本題重在理解without虛擬語(yǔ)氣的用法：
1. 與現(xiàn)在事實(shí)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(yǔ)動(dòng)詞：would/could/might (not) do sth.
2. 與過去事實(shí)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(yǔ)動(dòng)詞：would/could/might (not) have done sth.
3. 與將來事實(shí)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(huì)了。
謂語(yǔ)動(dòng)詞：would/could/might (not) do sth.
點(diǎn)評(píng)：虛擬語(yǔ)氣是高考每年的必考點(diǎn)，用法較多，平時(shí)學(xué)習(xí)應(yīng)積累鞏固。
