There will have an important international meeting in New York on July 6th. 单句改错还有computer was only invented decades ago. It is wide usde now and more and more people are interested in it

have错了 改成be
这是there be 结构 表示某地/某时等有某物，跟have/has的用法不一样，have/has表示某人有某物。这个句子中将there be 和have/has混用了。当然这句子中没有某人作主语的话，只能用there be 结构的。

There+be是固定结构，除了be以外不能用任何代替，故have应改为be

have - be

have 改为 be

There will be +后面不用改了

1、have改成：be
2、改正：Computer was only invented decades ago.It is widely used now and more and more people are interestend in it.
