sat语法题帮我改
Each time Mary turns on her computer,she has (A) to enter a company code,then her initials,and then enters a password (B) before (C) she can begin working (D).怎么改?
答
enter 去掉S，应为and表示并列关系
答
B 将enters改为enter
理由：前有has to enter....接着就应当是and then (she has to) enter......括号里面是省略的内容
has to的后面必须用动词原形。
供参考。
答
应该将B中enters去掉
可以发现本句结构如下
she has to enter （A,B ,and C） 这些A（a company code） B（her initials） C （a password ）是并列一致的,所以D 的enters多余了,破坏了平行结构,应当去掉
