　　1.A 本句是虚拟语气和真实语气的混合，逗号前面那句是虚拟语气，后面那句是真实语气，所以选一般过去时。句意：(我要是早知道你在这等我，)我就来早一些了，但是我并不知道你一直在等我。事实上我并没有来早，但是不知道你在等我是真实的。

　　2.A 逗号前那句其实是if从句，用的'是倒装结构，也可以是if she had found it

　　本句是对过去情况的虚拟，从句用过去完成时，主句用would+have done

　　3.A would rather 句后用动词原形表示虚拟

　　4.D it在这里是形式主语，真正的主语是后面的that从句，这也是虚拟语气的一个句型，但是要用过去式表示虚拟,并且be动词一律用were。还有行为动词的比如：Its time you went to bed. 篇7：小升初英语练习题与答案解析

　　二、单选

　　1. B 解析：一般说来，序数词如first,second等前面要加定冠词the，但是，表示“又一”，“再一”时，序数词前加不定冠词(a an),是 a second,a third的形式.本题翻译为，王平很擅长英语，他决定再学一门外语，再一 ，又一，用a second.

　　2.A 解析：many a +可数名词单数，谓语也用单数，但意思翻译为许多的。C选项没有这种用法，D中student要加s，而且如果选D，题干中的.动词用复数，是have而不是has.

　　3.D 解析：价格的提问方法1，what is the price? 2.how much is it ?,两者千万不要混淆。

　　4.B 解析：主从句时态要一致，when后是过去时，排除AC，family这里指的是家人，复数，选B。
