七年级英语选择:“I am sure you can speak English ( ) your sister.”

问题描述:

七年级英语选择:“I am sure you can speak English ( ) your sister.”
(请阐明原因)
a.as good as
b.as well as
c.so well as
d.much better

B.as well as:和.一样;
不能选择D,因为缺少than;因为speak是动词,所以用well,副词来修饰动词,(修饰动词‘SPEAK’用副词,排除A,而C用于否定句,D后应用THAN,即MUCH BETTER THAN,)
