1.tourist have been coming from all parts of the country to see it
2.the tourist have been picking leaves and cutting their names on the tree trunk.
这两句采自新概念二第58课.我想问的是第一句的coming为什么是动名词
第二句的picking.cutting为什么也是动名词?小妹这厢有礼了!^-^

第一句 因为有 been have been doing 在这里表示一种强调状态
第二句 have been doing 表示一直在做某事 从过去一直延续要现在
动词之所以要用 动名词 是因为它们要和前面的 助动词的时态相 配合
have/has been + doing
固定句型!!!
第二句中 and 表并列
所以 picking和cutting都为动名词!!!
have been就是动词了,一个句子中只能有一个动词,其他必须用动名词或者复合句(从句)来代替、
have been是该句动词,一句中只能有一个动词。
