7.I wonder how he_______for what n

1 B.should
should have done 固定搭配, 意为“本应做某事但事实上未做（含有责备等情绪）”，根据后文she changed her mind知Jenny未保持承诺

2 C.worthy
A.worth为介词,而该题所缺的为形容词
B.worthwhile指值得花时间做某事,与语境不符
D.worthy of实为be worthy of,个人未见过用worthy of充当定语的情况

而worthy在此处用做形容词,意为"相称的,配得上的",指奖励配得上Brown的教学

3 B.may
may have done 表示对过去的推测
A.should have done 表示 “本应做某事但事实上未做"
C.can have done 用于肯定句表示"本来有能力做谋事但实际未做"
用于疑问或否定句才表示对过去的推测
D.would have done多用于if 条件句的主句中表对过去的虚拟

4 C.Wouldn't
would rather 固定搭配, 意为“宁愿”，而will(won't)和do(don't)不与rather 搭配使用

5 A.should
if条件句的虚拟语气

在表示对将来的虚拟时，句型之一为
从句 If+主语+should +动词原形
主句 主语+would/could/might/should+动词原形

若省略if ，从句句型变为 Should +主语 +动词原形
主句不变

6 C.should
宾语从句的虚拟语气
当主句的谓语动词为 require ,ask,suggest等时，宾语从句应用虚拟语气should+动词原形,should可以省略

7 D.dared
