句子正确.it is said in the passage that“在短文中据说.”china has a population of 1300000000是主语从句,making it the largest country in the world是现在分词作结果状语.
问题补充中的
一、it is said in the passage that,having a population of 1.3 billion,china becomes the largest country in the world.这个句子可以这样说.不过,it is said in the passage that引导的是主语从句,不是强调句.having a population of 1.3 billion为现在分词作原因状语.
二、it has shown that he is so strong that nobody can push him down.也是主语从句.第一个that引导的是主语从句,第二个that是so...that句型,引导状语从句.
三、it is said in the passage that he point out that.也不是强调句,第一个that引导主语从句,第二个that引导宾语从句.
顺便说下,上面的所有that都可以省略,特别是口语中常省略.而强调句中的that是不能省略的.
