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

题目

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

答案

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,）
