我從網站上得知這雙靴子有男生和女生的尺寸。
一下是將上面句子以英文表達：
I know that this boots have size of two kinds such as men's and women's from website.
I know from websites that this boots has size of two kinds such as men's and women's.
我想請問上面哪一個英文是對的，還是都可以呢？
我第一句的想法是以名詞子句當受詞，
I know (名詞子句) from websites.
但是這樣後面的補語from websites好像又跟前面的名詞子句連成一串，不知道這樣有沒有問題呢？
懇請各位指導，謝謝。

兩者差異不大，但 this boots has size of two kinds such as men's and women's 很中式英文

給您參考 I know there are both sizes of men's andwomen's on the website.

當受格能省略that嗎?

謝謝解惑謝謝解惑

I know from the website that these boots have different sizes, such as a men's size and a women's size.I know from the website that these boots have two different sizes, such as men's and women's.
