—It's getting late.I really________go now. My daughter is home alone.

2.(2015·安徽黄山第二次质检改编)—I'm afraid I have to leave now, for you see, he is waiting for me.

—Well, if you ________， at least wait till the heavy rain stops.

答案：would/could/should/might　句意为：幸亏我们预订了一个房间，要不然我们现在就无处可呆了。根据语境可知，or后面的句子表示与现在事实相反的情况，此处为含蓄虚拟语气，句子谓语动词用“would/could/should/might+动词原形”结构。

答案：had been　句意为：如果我的车更可靠点儿的话，我去年夏天就会开车去拉萨，而不是坐飞机去了。根据语境可知，此处是对过去事实的虚拟，故if条件句用过去完成时，主句谓语用“would/could/might/should+have+过去分词”。

11.(2015·北京，34改编)If I________(see) it with my own eyes，I wouldn't have believed it.

(2015·广东省六校联考改编)

Drunk driving, a major concern currently, is not a funny thing, __1__ has killed many people and ruined the lives of many others. At present, traffic accidents become “the world's first harm”.

On the road near his home, an old lady was going across the road, __4__ his uncle didn't notice her and he was still moving on under the influence of alcohol. And __5__ old lady didn't see his uncle, either. In the end, the lady died.

__6__ it not been for his uncle's drunkenness, the terrible accident would not have happened. If the lady __7__(die), she would live a happy life with her daughters and sons. And his uncle's home was also destroyed by his uncle. Therefore, two __8__(family) were destroyed.

I wish more people __9__(can) realize the seriousness of drunk driving and obey the traffic regulationsfaithfully.Alwaysremember：refuse __10__(drink) and drive, and give a safe world to you and me!

1.______ 2.______ 3.______ 4.______ 5.______

6.______ 7.______ 8.______ 9.______ 10.______

答案：

1.which　thing后是非限制性定语从句，引导词在从句中作主语，故填which。

2.drinking　after在此是介词，后跟动名词。

3.heavily　修饰was drunk用副词。

4.but　由didn't notice判断，该空所用词表示转折，故填but。

5.the　特指上文提到的lady，故填定冠词。

6.Had　根据主句中的would not have happened判断，逗号前面是一个虚拟语气的条件句，句子的谓语应用had done形式;但是因为省略了if，所以要把had提前到句首，由此可判断出该空填Had。

7.hadn't died　if引导的是一个与过去事实相反的虚拟语气句子，故应用过去完成时，填hadn't died。

8.families　集体名词family在此是被看作整体，此处指“两个家庭”，应用其复数形式families。

9.could　wish后的从句用虚拟语气，此处表示与现在事实相反的情况，所以填could。

10.to drink　refuse后用动词不定式作宾语，refuse to do sth.“拒绝做某事”。　三、语法填空
