用＂is are＂填空 1.There __ some salad on the floor.2.There __ so

BE动词分为AM,IS,ARE三种,AM用在第一人称,IS用在第三人称,ARE用在第二人称,但后面都加形容词!

it is an apple
he is a student
she is a nurse
this is a ball
that is a cat
they are friends
these are dogs
those are oranges
there are some girls in the house
are you a teache

is,am,are都是be动词,简单的说就是“是”这个意思
is是第3人称单数用的也就是he.she,it他/她/它才用
am是第1人称单数用的也就是我 I,也只有I才用am
are是第2人称和 其他人称复数用的 ,你/你们,我们,他们
只要是复数就用are
She is beautiful.她美丽!
You are so kind.你真好!
They are Chinese .他们是中国人
It is a desk.这是张桌子
I am clever.我聪明

你的题目有点模糊.
我数了一下,总共13出括弧,我按顺序回答一下
1.is 2.what 3- 4.can 5- 6.do 7.not 8.9.10.sounds
11.fruit 12.runs 13.runners
Let us eat more furit every day!
What does your sister need for lunch!(ps;第二题是十个单词吗?）
仅供参考,自己看看适当修改一下

现在分词与be动词连用,构成进行时态,过去式用于过去时态,表示过去某个时间里发生的动作或状态.
哦,这样啊,见到oftenusuallyalwayssometimes通常用一般现在时态,now、at the momentthese days用正在进行时态,yesterday,,two days ago,long long ago,a minute ago,last year(week,month),just now,at that time,in those days.用一般过去时态.其余的时态我就不一一举例了.
反正记住,要根据时间状语来确定时态,不能根据be动词来确定,更不能瞎蒙.

is
注意:凡有单位名词的,以单位名词为准.
例:This box of apples is mine.

第三人称是指he she it 等 am用于第一人称 are用于第二人称
动词用单：主语是单数 不可数名词 复合名词 一个句子

is

what (are )you (doing ) now

Are Mike，s亲，对我的回答满意的话，就给个好评吧。如果还有不清楚的地方，可以跟我继续交流哦。为什么是are，下面是it's 啊是复数那下面是it is 啊，回答是is ，为什么提问是are那你就选is，但我认为是are求采纳为什么啊，我也觉得是are，但是下面那个is是怎么回事啊，给个解释啊因为pant是物体求采纳求采纳pant是物体跟is ，are 有什么关系人才能用a...

what is wrong with you 是对的。

is
为单数

答案是:is,is
因为,前面的"is" 是"a team"(单数）连用的,后面的 "is" 也是和 "a team" 连用．
前面那个"is" 很好选,但选后面的 is 的时候,关键要注意 win 这个单词．
"win" 是赢的意思,谁会赢?当然是 "a team"
这样解释应该能明白吧?

dollar为单数,
dollars为复数 i have two dollars
there is one dollar
The dollar also strengthened.
美元也同时走强
Let me change the dollar bill for coins.
让我把这张美元的纸钞换成硬币
Six dollars for a beer?
一罐啤酒六美元?

are friends
复数,所以都选复数形式

do does 用在没有助动词的地方 来补充的
is are 是系动词 一般用在 主系表的句子

用 is
three pints 三品脱的 其实是指 beer,因此是不可数名词做主语.
同例
Three days is not enough for us to finish the work.
现任高三英语教师,对语法应该说有一定的研究

are因为可数

is
bread是不可数名词,there be句型要遵循就近原则,所以不可数名词用单数is

1. do, does,did 要根据时态. do, does 用于一般现在时,当一般现在时的句子中谓语动词为原形的话,改为疑问加do eg. They like English. ------- Do they like English? Lucy and Lily come from the UK. ------- Do Lucy and Lily come from the UK ?而当一般现在时的句子中谓语动词后加s/es,改为疑问要在句首加does,并且将谓语动词改为原形eg. he likes english. -------does he like english? he teaches us english. -------does he teach us english?did 用于过去时的一般疑问句,同样看谓语动词是否用了过去式,改时放在句首,谓语动词同样改为原形eg. they wanted to go home. -------- did they want to go home? he liked to stay at home before. -------did he like to stay at home before?特别注意的是要仔细掌握不规则的动词过去式,尤其是跟原形一样的,举两例eg. he read the novel last night. -------- did he read the novel last night? the book cost him 30 yuan. -------- did the book cost them 30 yuan.2.is are,was ,were简单的就是看句中有无这些词,有就提前放句首,后面的不变.具体而言is are 在一般现在时中eg. he is a student. -------- is he a student? they are from Class 9 --------Are they from class 9?在一般现在时的被动语态中eg. english is taught in the school --------is english taught in the school在现在进行时中eg. they are watching TV now--Are they watching TV now he is listening to the teacher -------is he listening to the teacher在现在进行时的被动语态中eg. he is washing his car. =his car is being washed by hm ----- is his car being washed by himwas ,were在一般过去时中eg. he was late for school yesterday -------was he late for school yesterday在一般过去时的被动语态中eg. the teacher gave him a pen = a pen was given to him by the teacher --------was a pen given to him by the teacher在过去进行时中eg.he was watching TV at nine yesterday -------was he watching TV at nine yesterday在过去进行时的被动语态中eg.he was doing his homework from 7 to 9 last night.=his homework was being done from 7 to 9 last night by him. ---- was his homework being done from 7 to 9 last night by him被动语态的知识可能你还不了解,若是的话现在可放在一旁,不必急于弄清,等你以后学到便能融会贯通打字很辛苦,盼能被采纳

is
bread and meat属于不可数的食物,应该用第三人称单数
there be句型属固定搭配

3.There _are_ some babies in the room.4.There _are_ some sheep under the tree.

is
bread是不可数的

are（因为是两样东西）

was were

一般助动词后面都接动词原型 另外,情态动词can,will ,have to ,could,would,should,might,had to,was to,were to,must,ought to等在用法上,情态动词和助动词一样,后面接动词原型.只是要注意一些固定短语have to be u...

are the young 统指年轻人用复数

后面接物，如果物是单数用is复数用are，如果是一个苹果和两个香蕉，要看前面第一个是单数还是复数，一个苹果是单数用is了

1.有抓这个动作,所以用助动词,李太太第三人称,所以用does2.这句话隐含完成时,所以have done现在完成时.3.在一般现在时里,你一定要找到句子的谓语部分或表语部分.所谓谓语就是主语所发出的动作；表语就是能说明主语特...

have 是动词原形用于一般现在时.I have a book
has是动词的单数第三人称形式用于主语是第三人称的一般现在时 He has a book.
had是动词have的过去式用于一般过去时.He had an exam yesterday.

can be
情态动词+动词原形

用is

I am Bob.You can see a library.We school is nice.They are a bags.He is my brother.She is my sister.It is a ruler.This is a map.These are two maps. It is an eraser.It is pen.

are are are are
have have has has

there be句型中 be动词由紧接着be动词的名词决定
例：there is an apple on the table.紧接着的是an apple 是单数 所以用is
there is some water in the cup.因为water是不可数的 所以be 动词仍用 is.
there are some computers in the classroom.紧接着的是some computers是复数,所以用are
there is an apple and some oranges in the bag.虽然这里有两样物品 但是紧接着的是an apple 是单数 所以仍用is.
there are many students and a teacher in the music room.紧接着的是many students 是复数 所以用 are.

主语不可数时视作单数,所以用is/has/does.

用is
如 There is a lot of water over there.
The bread is delicious.

你混淆了几个概念.
be严格说,不能叫(am,is are)的原形.
而是说(am,is,are,was,were)都叫做be动词,只不过是不同时态人称下的不同形式.
而只有be才是原形.
这回你能明白了么?
希望可以帮到你.任何问题欢迎追问.英语牛人团祝您天天开心!

不是这样的.我也刚学的.被定语从句说修饰的是先行词,通常位于定语从句之前,而引导从句的是关系代词,如果先行词为人的.关系代词可以用that,who,whom而who,whom的区别是whom在从句中只作宾语.who作主语,
