动词

A) 第三人称单数

当动词是第三人称单数时，动词应该加s，如下：

一) 一般在词后加s

如：comes, spells, waits[weit等待], talks, sees, dances,

trains [trein火车n培训v]

二) 在x, sh, ch, s, tch后加es。

如：watches, washes[wɔʃ, 洗涤], wishes[wiʃ祝愿v], finishes

三)1)以辅音字母加y结尾的变y为i再加es。

如：study-studies, hurry-hurries ['hʌri匆忙], try-tries(尝试)

2)以元音字母加y结尾的直接加s。

如：plays, says, stays(停留、保持),

enjoys(欣赏), buys(购买)

三) 以o结尾加es。

如：does, goes

四) 特殊的有：

are-is, have-has

B) 现在分词

当我们说某人正在做什么事时，动词要使用分词形式，不能用原形，构成如下：

一) 一般在后加ing。

如：spell-spelling, sing-singing, see-seeing, train-training, play-playing, hurry-hurrying, watch-watching, go-going, do-doing

二) 以不发音e的结尾的去掉e再加ing。

如：dance-dancing,

wake-waking(叫醒、醒来),

take-taking(拿、取、接收),

practice ['præktis实习、练习] -practicing,

write-writing, have-having

三) 以重读闭音节结尾且一个元音字母加一个辅音字母

要双写最后的辅音字母再加ing。

如：put-putting, run-running,

There be句型

(1)There be句型主要用以表达“某处(某时)有某人(某物)。”其基本结构为“There be+某物(某人)+某地(某时)”其中there是引导词，没有词义;主语是be后面的名词， be是谓语动词，在一般现在时中be只用is和are两种形式。下面这首歌诀可帮你巧记there be句型结构：

There be放句首，主语跟在后。地、时放句末，强调置前头。There is a book on the desk. 有时为了强调地点，也可把介词短语放在句首。如：On the desk there is a book.

(2)There be句型中的be动词如何确定呢?请先看看下面这首歌诀：

Be动词，有三个，am，is还有are。“There be”真特别，不留am只留俩，那就是is还有are。要用is还是are，须看其后的名词是单数还是复数。若是单数或不可数名词用is，否则就用are。如：

①There is a tree behind the house.

②There is some water(水)in the bottle(瓶子).

③There are some pears in the box.

(3)注意：如果“be”后的`主语是由and连接的两个或两个以上的名词，那么be的形式要遵循“远亲不如近邻”的原则。也就是说，“be”的形式是由与它最近的那个名词来确定的。若那个名词是单数或不可数名词要用is，是复数就用are。如：

①There is a book and some pens on the floor.

②There are some pens and a book on the floor.
