Most of the Ming tombs ____south.(face)是要用原型还是过去式啊?

、、、课本后面 不规则动词表~

解题思路：大多数哺乳动物具有全身被毛，体温恒定，胎生哺乳等特征．

犰狳体温恒定，具有胎生、哺乳的特点，因此属于哺乳动物．
故选：D

点评：
本题考点： 哺乳动物的主要特征．

考点点评： 解题的关键是知道哺乳动物的特点．

最基本的原因就是情态动词之后要加动词原形 情态动词有2大功能 表本身的意思 还有就是表推测 当它表推测是 其后加be That's must be him.再有就是被动语态中含有情态动词时 其后必须加be　Trees should be planted by people every year.以满足它加动词原形的需要.

the least--- little,less,least
big,bigger,biggest
the worst,---bad,worse,worst

help sb do这里加不加都可以，make, let后面不用加to.

open 在此是形容词,“营业的”.整句话采用的是：主语+系动词+表语的结构

动词情况

（a-b)^2=a^2-2ab+b^2

got的原型：get
tomato的复数：tomatoes
saw的原型：see
sheep的复数 sheep

（B项“消”应为“销”C项“型”应为“形”D项“必”应为“毕”

swimming
Let's 是要加动词原形的
go已经是动词,不能在go后面加动词原形,所以不能用swim

一般的副词或形容词放在be动词的后面,实意动词的前面,这时动词不一定要用原型,该用什么就用什么,不受影响

make sb./sth.+@(形容词）
也可以make sb./sth.+v（动词）
eg：I made him laugh.

除了 USUAL 外都加ER
usua加 MORE

less healthy
不能用fewer,因为healthy不可数

举一反三，成语。从一件事情类推而知道其它许多事情。比喻善于学习，能够由此及彼。先秦·孔子《论语·述而》：“举一隅，不以三隅反，则不复也。”

eat是动词,eats是eat的单三形式,只有用在现在时并且主语是单数才会用到eats.例如：他吃饭 ：he eats.而 eating是动名词 可以表现有两个意思：1,他正在吃饭,he is eating; 2,吃饭的部分倒是最简单的 The eating part was easy.在疑问句否定句中是否用原型,要考虑到事态.如：1,他喜欢吃么?does he like eating?,2,他吃饭么?（他不是外星人吧?）Does he eat?这又是两个意思了

动词不定式的用法非常多,你们初中学的还比较少,出现最多的是用在结构中和表示目的.
be doing是进行时态的结构
介词后面不能加动词原形,要用ing形式,但请勿一概而论
like to do是一个短语,还可以用like doing,后面是不会用动词原形的,因为一个句子中只能有一个动词.
一个句子中必须有动词.
以上都只是通常情况而言,当然有特例.

没有~
常见的有：肯定：of courseceitainlyOKsureyes...
否定：sorry,I can'tI'm doing...

+do

不是,是因为一般过去时态的一般疑问句.助动词提问后,动词要要用原形的.这是语法规定的.

egin to do sth
开始做某事.动词原形.

是

Title: German fairy tale-like
Disney animation still remember signs? Lovely castle that `it is the prototype of the new Swan
New Swan Castle (Neuschwanstein Castle) also known as "Snow White Castle" is at the top of the myth Boqiang Blue Castle, Fussen is located in the town of Texas, in the Alps, was founded in 1869.
Germany's new Swan Castle (Nueschwanstein) castle is the symbol of Germany, no country in the world like Germany, as with so many of the castle, said there are still 14,000
To achieve his dream world, the Bavarian King Ludwig II built a palace, this is the new Fort Swan
Swan is located in the new Fort hills, towering mountain plateau in the back side of the lake-transparent, Vantage around slowly undulating forests, secluded natural scenery and the new Swan Fort dream-like appearance embraced.
King Ludwig II
Ludwig II of our countrymen known Qianqiangongzhu's cousin, said he has been Qianqiangongzhu Secret Love, he has not been completed in the new castles, Qianqiangongzhu送了一only porcelain swans congratulations, then Ludwig II of this castle on the naming of the new Swan Fort. He loves the arts, do not like politics. Therefore, this is a lonely king. Final Ludwig II and his physician to drown in the starnberger see.
Once something out of the dream world could not survive, therefore, always from the United States. Everyone should have one of their own castle, the castle in time no longer has any meaning to dream, to fly in the castle.

句子里没有任何时态说明 并且陈述一个客观事实

填goes to work.因为它的主语还是he,and表并列

动词后面不能直接跟动词的.was的话有几种可能： 1.是过去进行时,比如He was walking on the street when the accident happened. 2.was是谓语动词,那后面应该是形容词之类的,比如he was very handsome when he was young 3.was表示被动语态,后面应该是动词的过去分词,比如his wallet was stolen when he took the shower. 4.后面跟状语,表示位置时间之类的,比如the book was on the shelf just now. 其他的暂时想不出来了.我还真想不出动词的过去形式后面还跟动词原型的...您有例句的话咱们可以一起分析一下

是的,必须是原型,只要是情态动词都是加动词原形,不仅仅只有must,这里的must have done指的是对过去事件的肯定推断.

如果这个句子要说的是一个常见的固定习惯或情况时,就是原型
但如果你是用过去时,如：it was last month when she travelled to Shanghai.则就是过去时了
这要看情况的

是的,一定是动词原形开头.

动词的完成时

B

原型

感官动词+sb+do sth/doing sth
do sth表示动作全过程都看到或者动作经常发生
doing sth表示动作正在进行
所以，一般句子加了often表示动作常常发生，用do

名词,代词,动词-ing 形式

watch 有两种搭配：
watch sb.do sth.( 强调事实)
watch sb.doing sth.（强调过程）
不过其实我觉得这个句子还是用playing比较恰当

A
这里and是并列连词,连接两个并列句,前后时态一致.都是过去时

这里的mind是非及物动词,if以后就是虚拟语气了,表示尚未发生的动作.

e easy to do 固定短语

这是虚拟语气的一种情况.
在建议,要求,命令,想法后的动词后的从句里,用should + 动词原形,should 可以省略.如 advise,agree,command,decide,demand,determine,grant,indicate,insist,order,prefer,propose,request,require,stipulate,suggest,urge,vote.
例：She had requested that the door to her room be left open.

一个句子里只能有一个谓语
动词要并列的话,只能将第二个动词表示为现在分词作伴随状语

系动词是用于主系表句型当中的词,后面一般跟名词或形容词,系动词包括be动词和感官动词
原型就是它本身的面貌,没有变化,be动词有am,is,are,这就是它们三个单词的原型
Why do you 后面加动原表示为什么不.的意思 也相当于 why not 加动原.

had better do
must/can/may/ do
let ~~do
help~do

太……,如
He is too old to go to work.他太老而不能工作.
