4.7some questions

I’m a beginner and the videos I’ve watched are from the 4.2 textbook, which has a lot of components, I’m using 4.7 but I can’t find them in 4.7, such as the works task component in the work library and so on.
Can anyone help me to find it?

The Works component library is deprecated, so learning it is not very useful and recommendation is to use Process Modeling instead.
However, it is possible to add eCat of older versions to your installation from the eCat sources.
