A.as B.what选哪一个？为什么？

选A

as is usual像往常一样（是固定搭配）

David gets up esrly and takes exercise in the morning,__is usual with him.

David像往常一样早上早起锻炼

B.缺主语嘛，只有B了

选A

首先说明的是这是一个非限制性定语从句，非限制性定语从句只能由两个词引导 which和as 这里面只有后者故 a是正确选项

A,是固定搭配

A

as代表前面的句子，表示对前句的补充说明

David gets up early and takes a walk in the moring,( )is usual with him. ___is always his habit, he gets up early . He will ring you up __ he gets to Beijing. She gets up at six o'ciock. ----David has made great progress up till now. ----____,and_____. He gets up ( ).A.late B.lately 为何不选B？ gets up early 为什么要在"get"后面加"s" he usually gets up at 17o'clock.的否定句 he usually gets up at 17o'clock.变否定句 Lulu always gets up at six o'clock(用at six o'clock)
