4．这些丝绸围巾是手工制作的．
These silk scarves are made by hand．

Answer 1

分析 These silk scarves are made by hand．

解答 答案：These silk scarves are made by hand．
表达的是客观事实用一般现在时，主语These silk scarves是动词make制作的承受者，构成被动关系，故用一般现在时的被动语态am/is/are+过去分词，主语是复数，故are，make的过去分词made，by hand手工的，故答案是These silk scarves are made by hand．
