The population of China is more than 1.3 billion by now.应该是正确的.您说呢?The population of China has been more than 1.3 billion by now.大家都知道是正确的.上一句也应该正确吧?

问题描述:

The population of China is more than 1.3 billion by now.应该是正确的.您说呢?
The population of China has been more than 1.3 billion by now.大家都知道是正确的.上一句也应该正确吧?

第二句是正确的,但第一句就不是很好了,时态不是很好

第一句不对,因为有by now,是现在完成时的标志

完全正确
