China daily is --- a newspaper.It helps us improve our Engli

答案因该是 c
其实应该是 china daily is more than a newspaper as it helps us improve our english.
但是如果是这样的话,C 还是比较好的答案.
如果单单是 china daily is _ a newspaper.
ABCD 都可以.
但应为后面有 it helps us improve our English,
所以 ABD 都不能用.
ABD 的意思=就是
如果 china daily 就是报纸,这么能帮我们提高英语水平?（普通报纸）
所以如果 china daily 比普通报纸还好,这样的话也就能帮我们.
