The girl is dancing over there. 看!那个女孩在那里跳舞。Can you go and play games with me? 你能和我们一起做游戏吗?Cant you see I am doing my homework? 你没看见我正在做作业吗?6、have/ has的用法：1) 谓语动词have表示“有”，有两种形式：have和has，前者用于第一人称(I, we)，第二人称(you)和第三人称复数(they)，后者用于第三人称单数(he, she, it)或单数名词。I have an apple and he has two bananas. 我有一个苹果，他有两个香蕉。You have a new English teacher. 你们有了一个新的英语老师。It has two big eyes. 它有一双大眼睛。Julie and Jack have a nice car. 朱莉和杰克有一辆好看的车。2) have/has句型与there be句型的比较：两者都表示“有”，但用法不同。前者表示所属关系，即表示“某人或某物有什么”，而后者表示存在，表示“某地有什么”。They have some new books. 他们有一些新书。There are some new books on their desks. 他们桌子上有一些新书。She has a lot of pretty skirts. 她有很多漂亮的裙子。There are a lot of pretty skirts in the shop. 商店里有很多漂亮的裙子。3) have/ has的否定句，一般要加助动词do/ does，再加not构成，即do not have (dont have)/ does not have (doesnt have).
