一道英语语法题———from the number of the car parked,there can't be m

———from the number of the car parked,there can't be many people at the stadium yet . 为什么答案是问题补充：
为什么不是when we judged 呢?
答：这是我搜索到的典型题.答案是A.
8. _____ from the number of the cars, he thought, there weren't many people at the restaurant yet. A. Judging B. Judged C. To judge D. Being judged
析：Judging from/by都可以,Judged 只跟by,不跟from, 排除B.
C.表目的.（实际上有这样的例句,考试英语不承认）,排除C.
D. 结构错误,不用考虑.
你的问题,可能是因为有人改题了.但没有这么改的吧?
如果用When从句,也可以,但时态不对.因为原题句的主句是there can't be 是对现在情况的推测,应改为：when/if we judge from the number of cars parked, .

也可以用句子，不过此句最好用一般现在时态

填judgying
一般的词组是 judge from sth. 从……上判断出来
judge by sth. 通过……判断出来
意思差不多
如果前面是人做主语的话，一般是sb. judge sth.
sb. judge that
sb judge sth. from ……
Judgying from……， ……
或者judgyin...

Judging是吧。judging from可以当做固定搭配来记住。意思是看起来…… 从……判断
