1. sweepstake，现在时态的用法？
（一）定义
一般现在时主要用来表示经常性或习惯性的动作，或者是现在的特征或所处的状态。如：
He often goes to school on foot every morning.
She is at work now.
They are primary school students.

（二）基本结构
从谓语动词的分类来看，一般现在时的基本结构主要分三种情况，即：
1、主语+be+其他成分
其中的be，会随着主语的不同，有am/is/are的变化。am的主语是I，is的主语是第三人称单数，are的主语是第一人称复数、第二人称的单数和复数、第三人称的复数。如：
I am ten years old.
He is in the classroom.
They are in the zoo at the moment.
2、主语+do/does+其他成分
其中，动词do的主语为第一人称的单数和复数、第二人称的单数和复数、第三人称的复数，does的主语为第三人称的单数。如：
We always stay up late on Saturday.
You often forget to bring your textbooks with you.
She likes apples very much.
3、主语+情态动词+be/do+其他成分
此时，情态动词采用的是现在形式，后面的动词都采用原形。如：
She can be a good teacher in the future.
I must leave for the party now.

（三）动词的第三人称单数
动词的第三人称单数，简称三单，是在使用一般现在时中最容易出错的地方。这与汉语的主谓成分在数上没有一致性要求有很大关系。
动词三单常见的变化规则有：
1、直接+s
如：works、plays、sweeps。
2、“伤心城市”（即以sh、x、ch、s或ss结尾的单词）加+es
如：washes、fixes、watches、focuses、kisses。
3、以辅音字母+o结尾的+es
如：goes、does、vetoes（否决）。
4、以辅音字母+y结尾的，改y为i，再+es
如：studies、flies、dries。
5、特殊情况
如：have的三单形式为has。

（四）常见用法
1、表主语现在所处的状态
The book is on the desk.
I am very busy.
2、表主语的身份或职业
She is our English teacher.
His father is a doctor.
3、表主语的特征或特点

The train leaves at four tomorrow afternoon.
She comes back home tonight.
11、表将来（在时间和条件状语从句中）
If he comes, I will tell him about it.
When the plane arrives, she will meet him herself.
12、用在格言、警句中
Pride goes before a fall. （骄必败。）
Time is money. （时间就是金钱。）
13、表过去

She tells me Jack will come tomorrow. （她告诉我杰克明天要来。）
I hear that he won the first prize in the competiton last week. （我听说他在上周的比赛中得了第一名。 ）
2）当要陈述一个客观事实时，有时即使有过去时间状语也可用一般现在时。如：

He can drive a car.
He cannot (或can't) drive a car.
She is on the playground.
She is not (或isn't) on the playground.

如果要转换为一般疑问句或对划线部分提问，需要借助助动词do/does，提到句首，原有动词要恢复原形。如：
