my sister and l 在句首,为何不用丨and sister？

my sister and me / my sister and i 有什么区别

意思一样! me是宾格 用于介词后面.主格用于陈述句和放在句首.

“there are my family,my parents、my sister and i”为什么用 i 不用me -.

and用于并列句式.前面并列的my family,my parents、my sister 都是主格所以用第一人称的主格形式i而不用宾格

＂They are sister and brother＂sister and brother为什么不用复数?

If there is one brother and one sister,I would say: They are brother and sister.

My sister and I 的谓语要用 is 还是are

are

是 my sisiter and i 还是 my sister and me?还是两者都可以

在句子中做主语 用 my sisiter and i 在句子中做宾语 用 my sister and me

是my sister and me还是ma sister and

my sister and I,主语,把my sister 放前面是礼貌.

My sister and I-----.

C.are doing our homework指的是两个人 用复数希望对你有帮助

my sister and i were at home.为什么用were不是was????

因为主语是复数,复数作主语时,be动词的过去式要用were

I am with my sister等于my sister and I吗

不能说等于,意思上是一样的,但是前者是一个完整的句子,后者是短语作主语.

My sister and I look different.为什么用look

看起来 希望对你有所帮助look 可以作为不及物动词 表示,可以来沪江小Q提问,如果还有英语问题
