1. 复习现在完成时，一般过去时

三. 具体内容：
（一）1. 现在完成时：

　　They have just finished their voluntary service.
　　也可以描述从过去开始并持续到现在的动作或者描述经历.

　2. 两种时态的区分
　　（1）一般过去时的谓语动词用过去式，
　　而现在完成时的谓语基本构成是“助动词have /has +过去分词“。
　　（2）一般过去时通常与表示过去的时间状语连用。如：yesterday， last week， two years ago， just now， in 20xx等\；而现在完成时则常与just， already， ever， never等副词和these days， this week， since...， for...等表示一段时间的状语连用。

（二）there be 和have/has的使用。
1. there be 表示某地有某物，某处存在某物，不表示所属关系。there be 后的名词是主语，主语后的介词短语为地点状语。
　　There is a ball in my hand.
　　There are some apples in the basket.
　　Is there any water in the glass?
　2. have/has 是拥有，占有的意思。它表示一种所属关系。
　　I have a pen in my hand.
　　I don‘t have any car.
　　Do you have any computer?
　3. 表示单位的组成，构成时，have 和there be 可互换。
　　A week has seven days./ There are seven days in a week.
　　A year has four seasons./ There are four seasons in a year.
