2.you didn’t reach the required level,______,you faild in the diving test.

选C 请问有没有A项的表达?那改成in other words 是不是对的?

keep .from..
from不能省略,后面加 所要防止发生的动作
如果省略了,就变成keep.,那就是 保持 的意思,保持屋顶掉下来?不对
首先,没有in another word这样的说法
that is to say=in other words=换句话说,也就是说 的意思
that is ,(插入语,)那意为着,也就是说(和上面的一样)
B是错在 两个短语不能连在一起用,太重复了

1. prevent 是 v
2. 可以改成on the other hand

没有IN ANOTHER WORD. 只有IN OTHER WORDS
