题目内容：

英语 people are has found
people are(为什么有are,没有不行吗?) has found more than half of adults are so idle（这里可以有that吧 是被省略了吗） they'd catch the lift rather than climb two flights of stairs.
这是“BBC英语教学”里的原句啊。
英语教学错了？还是这是很口语化的表达方式啊？

正确语法不应该用"are",'has' 应该是 ‘have',因为 'people' 是负数 'that' 应该在 ‘found' 后面,’idle‘后面不需要加 'that'或插入 'so...that...'形式.'they'd' 是不正规的缩写,的正确写法是 'they would'.
正确的句子应该是：
"people have found that more than half of adults are so idle they would catch the lift rather than climb two flights of stairs."
