Landlord, you didn't say the topic, but you received a tutor from Wuyi Family Education Network. If you want to prepare lessons, you can go directly to the lesson preparation center to find electronic textbooks.

First of all, the textbook here in Wuhu is People's Education Edition, so we choose People's Education Edition in the lesson preparation center.

Then, I helped you find the next, fourth grade math catalog:

1 four arithmetic operations 2 position and direction 3 arithmetic and simple calculation The significance and nature of nutritious lunch 4 decimal 5 triangle addition and subtraction 6 decimal 7 statistics 8 mathematics wide-angle housekeeper 9 general comment postscript

As for Chinese and English, there are too many words. You can find them according to my method.

Finally, for the code word, remember to adopt it and reward it!
