Based on the image, can you identify and transcribe the Chinese characters and their associated pinyin, and then translate the sentences into English?

Here's the transcription of the Chinese characters, their pinyin, and the English translation:

1. 明天是我们 (Míngtiān shì wǒmen): Tomorrow is us. (This is grammatically incorrect.) A better translation based on context might be: Tomorrow it is our turn. Or: Tomorrow, it is us (who are doing something). However, without further context, it is difficult to give a definite translation.
2. 我们去商店 (Wǒmen qù shāngdiàn): We go to the store (shop).
3. 的礼物是书 (De lǐwù shì shū): The gift is a book.
4. 书店 (Shūdiàn): Bookstore.
