This can't be a very good way of teaching can it?? First thing in this chapter you get to pair 6 words/expressions with 6 pictures. Only, these words aren't even introduced until later in this chapter?? (Also, notice how no 4 is "friends", which match two pictures and you can only figure out which one by looking ahead at no 6, "Chinese friends"...)

There was a similar thing in the workbook tests for the previous chapter. You were supposed to answer a few relatively simple questions, but the questions contained words the books haven't covered yet, and there were no information on what they meant.

I mean.. this isn't a me-thing, right? This is a terrible way of teaching, yeah?
Come to think of it, doesn't language apps do something similar? Give you a word you don't know and some pictures and you're supposed to guess which one it is. Is this, like, an actually valid teaching strategy after all? If so, it's absolutely terrible (for me at least) :P
They do the same thing in the next chapter's/lesson's exercises too, so this seems to be pretty consistent.. And very demoralising.. ​
@vae it works for some, but definitely not for everyone. I have no idea about Chinese, but some languages and the cultures they evolved in are different enough from ours that there is no easy mapping. You can't simply say "this word in their language is that word in your language" in those situations. Pictures are vague enough to convey that. For some.
