请教几道高中英语语法题,说明理由?
1,Would you like a cup of coffee_C___shall we get down to business right away?
A,and B,then C,or D,otherwise
2,They want to know _B___do to help us.
A,what can they
B,what they can
C,how they can
D,how can they

1,选择关系,喝杯咖啡和开始工作是,两者只能选其一。故填or。2从句中用陈述句的顺序,排除A,D.主句中know缺宾语,How为疑问副词,不能作宾语,What为疑问代词,可以作宾语,故排除C,选B

1、A。and:和、并且;B。then:然后;C。or:或者;D。otherwise:另外
句子是,你想要来杯咖啡(或者)马上谈正事。有了right away,个then就不行。
2、句子是陈述句,后面不用倒装;
他们能做什么,而不是怎样做,来帮助我们

1楼的答案是正确的,但是第2题的解释是有问题的,how是疑问副词,但是可以引导宾语从句,此处不能选C的原因是how they can do缺少宾语,就是说从句是不完整的
