高中英语单项选择 求解释

If you live in the country or have ever visited there, ____ are that you have heard birds singing to welcome the new day.
A. situations B. facts C. chances D. Possibilities
答案是C 本题考查名词语意的选择。在此处chances的意思是“有……的可能”。本句句意为“你就有可能听到小鸟歌唱来迎接每一天。”

看不懂解析…想问下“chances are that you have heard birds singing ”是什么结构？

Answer 1

chances主语
are系动词
that you have heard birds singing 表语从句
chances are that...典型的非正式用法，相当于It is likely that..... 意思为“有可能..（发生怎样的事）..”但注意，后面这个句式就是it形式主语+that主语从句了。
用非正式用法来出题，可以看出中国考试变态到何种程度了，西安交大有一个美国留学生，期末考英语不及格................

Answer 2

chances are that......... 是一个固定句型，其中that 是可以被省略的，意思相当于there is a chance that........., 或者It is possible that .........
