Question

Sandy和她的朋友们 用are还是is?什么情况下用is?什么情况下用are?
如上.
“usually”和“often”后面的be动词是因为人称而变化的吗.如果人称是she/he/it以及人名,那么是不是就用is?那么如果是She and her friends/family ,be动词该如何变化?

Answer 1

Sandy and her friends are ...
说明：Sandy and her friends 是复数（很显然不是一个人）,作主语时,be 动词必须要用复数形式 are 才行.
usually 与 often 是频度副词,对句子的主谓一致原则没有影响.例如：
1、He usually goes to school on foot.
2、Mary often comes to work at seven thirty in the morning.
be动词的用法说明：
be 动词有三种变形,分别是：am,is,are.
第一人称单数：I 用 am ,第一人称复数 we 用 are ,
第二人称单数与复数相同,都是 you ,要用 are ,
第三人称单数 he / she / it 要用 is ,第三人称复数 they 要用 are ,
例句：
1、I am a teacher of English.
2、We are all Chinese.
3、You are a student,aren't you?
4、Are you basketball players?
5、He / she / is a bus driver.
6、It is a book.
7、They are playing soccer on the playground now.
be 动词用法记忆口诀：
“我”用 am “你”用 are ,
is 用于“他 / 她 / 它”；
“单数”全都用 is ,
“复数”全部都用 are .
