实义动词的一般现在时
一、什么叫实义动词？
实义动词是指表示某种动作行为,有具体意思的动词,也叫行为动词。如:
like,
eat,
live,
have,
run
等等，它们的意思分别是：“喜欢”、“吃”、“居住”、“有”、“跑”等等，这些都是实义动词。实义动词占英语中动词的绝大多数。
我们已学过的be
动词的一般现在时，be动词可译成“是”，有时译成“成为”，有时则没有具体意思如：
“She
is
tall.”
这句译成：
“她很高”。故be
动词不属于实义动词。
二、人称的划分
1.
第一人称:
I,
we
第二人称:
you
第三人称:
he,
she,
it,
they,
Millie…
2.
第三人称单数:第三人称中指一个人或事物的代词或名词,如:
he,
she,
it,
Millie,
his
friend,
the
dog
等。
你能再举出一些第三
人称单数的例子吗？
三、
一般现在时实义动词作谓语时的动词形式：
一般现在时实义动词作谓语时的动词形式有两种:动词原形或第三人称单数动词形式。如:
enjoy叫原形,
enjoys叫第三人称单数形式。
四、实义动词第三人称单数的
动词形式变化规则:
绝大多数动词
+s
walk—walks
辅音字母+y结
尾的动词
将y改为i+es
fly—flies
以s,
x,
ch,
sh
结尾的动词
+es
watch—watches
一些以o结尾的
动词
+es
go—goes
do—does
