grammar 一問

呢句o既結構係點？答案係：錯o既。
如樓上所講，其實句子可分成兩部份：
１．The earth goes around the sun －呢部份係全句o既 subject
２．X is known to everyone －X就係主詞
本句中文意思為「地球繞太陽轉動人所共知」。咁樣o既中文句完全無問題，但直譯為英文，變成：
The earth goes around the sun is known to everyone.
就大有問題，因為正如你所講，本句有兩個 verbs：goes 同 is。問題出於，一句完整句子本身唔可以成為另一句子o既主詞。唯一方法，就係將要變主詞o既句子變成一個 that clause。即係：
That the earth goes around the sun is known to everyone.
咁你睇唔慣，但如果 that clause 做受詞，你又可能好熟悉：
Everyone knows that the earth goes around the sun.
即係話，that clause 可以作為名詞。

The earth goes around the sun 為其中一句的子句; 屬 "主句 " main clause 說出主題.

is 是兩句子句的動詞.

known to everyone是另外的一句子句; 屬 " 述句 " predicate clause.

Re : is known 是被動的語氣 ( passive voice );即前面的一句提及的情況讓每個人知道.

整句文法沒有錯.

I think the verb is actually "IS"
This sentence can be broken down into two parts:
1st: The Earth goes around the Sun <-- this is a complete sentence
2nd: Known to everyone <-- this is NOT a complete sentence
and that they are linked with an "IS"
