句子结构剖析与正误判断

If anything we can give assistance,you may just speak to me.

这里的anything后面的应该是定从吧？但we can give assistance这句子完整吧，那样不定代词anything在句中充当什么成分？

假如要改应该如何改？

If anything we can give assistance, you may just speak to me.

此句错误。应该让 we can give assistance 和 you may just speak to me，并列起来。改为：

If anything （从句）we can give assistance and you may just speak to me.（主句）

if anything 是习语，意为“要说真有哪些的话”。

【翻译】要说真有哪些事情发生的话，大家可以提供帮助，你尽管跟我说。
