His sister is name is Lucy改为一般疑问句

Is his sister`s name Lucy

原句应该是His sister’s name is Lucy
Is his sister's name Lucy!
把be动词提前 构成一般疑问句

句子有问题，应该是His sister's name is Lucy.
Is his sister's name lucy?
一般疑问句
这种问句通常用yes ／ no来回答，相当于汉语中的“……吗？”
语序是：系动词be ／ 助动词／ 情态动词＋主语＋其他成分？如：
Are you from Japan？
Yes I am． ／ No I'm not．
Is her sister doing her homework now？
Yes she is． ／ No she isn't．
Does he work in a bank？
Yes he does． ／ No he doesn't．
Do you live near your school？
Yes I do． ／ No I don't．
Can you speak French？
Yes I can． ／ No I can't．
May I go home now？
Yes you may． ／ No you mustn't．
注意：
1．将陈述句变为一般疑问句时，如句中有be 动词（am is are …）时，可直接将它们提至主语前。如主语为第一人称，应将其改为第二人称。如：
I'm in Class 2Grade 1． →
Are you in Class 2Grade 1？
We're watching TV． →
Are you watching TV？
2．陈述句中有情态动词（can may must …）时，也可直接将它们提至主语前，即可成为一般疑问句。如：
He can swim now． →
Can he swim now？
The children may come with us． → May the children come with us？
3．陈述句中只有一个实义动词作谓语且其时态为一般现在时，变为一般疑问句时要在句首加do或does 主语后的实义动词用原形。如：
I like these animals． →
Do you like these animals？
She wants to go to the movies． → Does she want to go to the movies？
4．一般疑问句一般读升调(↑)
5．一般疑问句有时不用yes或 no 回答。如：
Are they in town now？
I think so.
May I sit here？
Certainly．
Does he like soccer？
Sorry I don't know．

Does his sister’s name is Lucy?

Is his sister's name Lucy?

Is his sister'name,Lucy?
才是最标准的。

应该是His sister's name is Lucy.--Is his sister's name Lucy？
