1 he must be helping the old man to water the flowers,----B---?A is he B is not he C must he D must not he 2 ---C---makes his shop different is that it offers more personal services A what B who C whatever D whoever 3 gun control is a subject ---C---
1 he must be helping the old man to water the flowers,----B---?
A is he B is not he C must he D must not he
选择 b 因为must 表示肯定推测的时候,反义疑问句看他后面的be,所以这里面应该是is 又因为前面是肯定的,那么后面的用否定
2 ---C--makes his shop different -is that it offers more personal services
A what B who C whatever D whoever
选择a 你的答案不对 c选项是无论什么的意思,翻译不通
选择第一个 翻译成 使这个商店不同的就是 他提供更多个人服务what makes his shop different 作主语
3 gun control is a subject ---C----Amercians have argued for a long time
Aof which b with which C about which D into which
选择c 这里的argue about 是固定词组 ,介词about可以提前在which前

1.must 在这里表示一定，是猜测的语气，而不是必须的意思
在这种情态动词表猜测语气的句子中，反义疑问句用be动词反问，而不是情态动词
2.……不会，我觉得选A
3.argue about something:争论……
这句话可以改成：
gun control is a subject that/which Americans have argued ab...

1.must 在这里表示一定，是猜测的语气，而不是必须的意思
在这种情态动词表猜测语气的句子中，反义疑问句用be动词反问，而不是情态动词
2.……不会，我觉得选A
3.argue about something:争论……
这句话可以改成：
gun control is a subject that/which Americans have argued about for a long time.
这里就是把介词about提前了

收起

1 .因为有be在句子中，所以反义疑问句应把be提前，又因为主语为he所以用is,只有当be在句子中不存在时，才把must提前，所以选c

1 D
2 C
3 B

1.B
2.A
3.C

1 must表示推测 而句子侧重时态 so 用isn't he
2.A 引导主语从句 what 指物
3.C 短语argue about sth with sb，which是定语从句中的关系代词
