I hope you don't mind @miyaliu666, I pushed some minor fixes. Take a look at the diff to see what I changed, or let me know if you want me to show you.

This looks good. The only concern I had is that the first two task descriptions are the "Practice time" style. Do we want to start with two tasks that don't explain anything and just throw users into it? I'm fine with it, just mentioning it.

@naomi-lgbt I used "Fill in the blanks in the dialogue below" and "Please answer the question below" in Part 9 and 5 after I saw your comments here.

I'll add explanations for words in the first two tasks as @moT01 pointed out. Those words have been taught in previous blocks, but we can review them here because people may not learn the blocks in strict order.

LGTM 🎉
