(完整版)一般现在时态讲解及练习(精简版,错题版)

一般现在时态

一、一般现在时的用法

1) 表示经常性、习惯性的动作或存在的状态。通常与副词sometimes, often, usually, always, every

day (year, month ), once (twice, three times) a day, 等等频率副词（时间状语）连用。

e.g. They usually go to school by bike.

I take the medicine three times a day. 实义动词表示“动作”

She helps her mother once a week.

Mary’s father is a policeman.

There are 50 students in my class. Be动词表示“状态”

He is very busy now.

be 、do不能放一起，如果非要放一起，do后要加ing, 变成现在进行时。

2) 表示主语的特征、性格、爱好等。

e.g. I work hard.

I like watching TV.

3) 表示客观真理

e.g. There are seven days in a week.

The moon moves round the earth.

The sun rises in the east and sets in the west every day.

Tomorrow is Tuesday.

二、一般现在时的句子转换：

三、一般现在时的结构：“主语+谓语+其它”，有时为了起强调作用，时间状语也可提前.

三单变化：

1）多数在动词后＋s ：

play — plays like — likes ask---asks work---works get---gets stay---stays 2）以字母s, x, ch, sh或o结尾的动词，+-es：

watch---watches wish---wishes fix---fixes do---does go---goes pass---passes 3）以“辅音字母加- y”结尾的动词，要先变y为i+-es.

try---tries study---studies cry---cries fly---flies

不规则变化：be---- is are have----has

做题时常见错误如下：

1）、be动词与行为动词同时出现在句子中

例：We are plant (plant) the trees in spring.

答案：plant

2）、单三人称形式易出错

例：1 He plaies (play) football very well.

2 Danny gos (go) to school at 7:10.

答案：1 plays 2 goes

解析：1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es；

2与名词变复数不同，变单三人称形式以o结尾的词要加es.

3）、在句式变换时易出错

例：1 Does Jenny has (has) a good friend?

2 Brian doesn’t lives (not live) in China.

答案：1 Does have 2 doesn’t live

解析：口诀：“见助动，用原形”。此口诀用于一般过去时态中。e.g. He didn't go home yesterday.

4）、对do的理解易出错

例：We don’t (not do) our homework in the afternoon.

答案：don’t do

解析：do是一个比较难理解的词，它有三个含义:

a)是所有行为动词的总称；b)是助动词，无实义；c)是一个具体的行为动词“做，干”。

此句中给出的do指“做，干”，not指把此句变为否定句，故须在do前加助动词don’t。

5）、对主语的数判断有误

例：Li Ming with me are (be) in Beijing.

答案: is

解析:表面一看是“我和李明两个人在北京”，但with在此做伴随状语，不能做主语，故用is.
